RE: Unix Trouble
This is *exactly* why you never run as root unless you absolutely have to (even then you can often get away w/ running only the current command as root using su). First suggestion is restoring from your daily backup. You *do* have a daily backup don't you? :) As far as recovery goes, assuming that the OpenBoot security level is not set to full you should be able to quickly recover with the help of the Solaris CD. Basically it will consist of booting off the CD, mounting the partition that normally contains /etc (and the partion where you think it went), and restoring it to it's proper location. For more exact details on how to do the boot and mount, you should be able to find some FAQ or info on one of the many Solaris sites ( http://directory.google.com/Top/Computers/Software/Operating_Systems/Unix/So laris/ ) or your favourite Solaris book. -Original Message- From: Erika L.

RE: Compromising Security
Code smart. Don't allow input from a form field to ever go directly into a query: Treat all data recieved from a user as tainted. Don't rely on JS or HTML, there's nothing to stop someone doing a direct post to your script. Get rid of detailed error messages, use error templates and try/catch to make them user friendly (and disable in admin). Give CF only the permissions it needs, don't run as a dbms su when select/insert/update permissions are all that's needed for the main site. Use stored procedures, not only do you get the benifit of added speed and lower connection overhead (though portability can be effected) you can more readily control exactly what is being accessed. There are tons of other suggestion, such as always staying on top of security updates (unlike 60%+ of sysadmins out there who don't patch known issues even years after they've been dicovered and documented). It doesn't take much extra coding, and it quickly becomes second nature.

RE: What a task!
Haven't really been following this thread, but at it's highest level your problem seems to break down into these three steps. (If you want quick fixes skip to the bottom.) 1. Render the HTML 2. Convert rendered screen to image 3. Resize image RENDER THE HTML --- You might check out http://www.mozilla.org/ for mozilla's HTML rendering engine if you want something you can bring into your own code. There are some other engines that are open as well, I'll leave them to you to find. Alternately there's closed source such as the popular IE. Which you decide to use counts heavily on the next step. CONVERTING TO AN IMAGE -- The whole purpose of the exercise is to get the render (R) to output to a bitmapped image (I). Theoretically the easiest way would be get R I; somehow I doubt it's going to be as easy as a 'mozilla --url=www.foo.com bar.jpg' though. Given the mozilla source you may be able find where you could redirect the screen display though. I'm not overlly familiar w/ IE but it might have some COM objects accessable to pull the information from. RESIZE IMAGE So many programs and algorithms to accomplish this, choose whichever suites you (http://www.imagemagick.org/ is one of my favourite utils for this). CONCLUSSION --- I realise this isn't exactly detail specific, but if you were floating around wondering how to even begin tackling the problem this might provide some grounding. QUICK FIXES --- http://www.html2jpg.com has a win9x/IE5 specific program to accomplish step 1 and 2 if you're on that platform. http://www.tdb.uu.se/~jan/html2ps.html converts to PS, w/ http://www.imagemagick.org/ it's only a step away from a properly sized jpeg and it's not platform specific.

RE: Array problems

RE: setting values
Mapping values is one option, but I really think you should consider leaving it numeric. update prod set price = 19 where price = 22; Would easily change all prices of one type to another. If it's space you're concerned about (and you use all integer prices) using an unisigned tinyint (8 bits) will give you values from 0 to 255 and take the same space as char(1). Really though even a dec(9,2) isn't bad at all for only a few thousand records. As far as input is concerned, just create a dropdown or the like so you can quicky choose the standard values. This will keep the data w/ the prices relevant and cut out the need for a join table (and application array/struct) as well as the need to work w/ a sting. If you do want to do a mapping, here's a way. CREATE TABLE table_name ( code char(1) not null, price decimal(9,2) not null PRIMARY KEY (code) ); Then just create a relation w/ cascading update to the products table. You can now either enumerate the code w/ a join in the query, or use an application struct so #application.price[query_name.price_code]# fills in the value (after do all the locking etc.). It really doesn't make sense from a complexity and speed view though, when a dropdown on input would solve all your problems. -Original Message- From: Ken Ketsdever [mailto:[EMAIL PROTECTED]] Sent: May 18, 2001 18:32 To: CF-Talk Subject: setting values Friday, May 18, 2001 5:14 PM I have a table that is dynamically populated from a db to show the item number, description, price and image of products.

RE: HELP: Hierarchy
Sounds like you'd be best be served by a recursive function (or for CF
recursive custom tag).
For performance sake I'd either have a table or application object to store
the full heirchy info of each category; pre-generated on a fixed basis.
You could store it w/ full html formating in a table/array:
| cat_id | generated_data
---
| 5| a href=blah... a href=
Or if you wanted a more flexible approach an array of struct containing the
cat_id and cat_name (wddxed into that field if a db or flatfile).
array[0]-{24} = 'Sevier County'
array[1]-{6} = 'Arkansas'
array[i]-{cat_id} = cat_name
(Alternately a 2D array would accomplish the same thing w/ better
performance but this is for clarity)
I'm using a Perlish notation to show the relation a bit more clearly (I
hope).
Whether you use a temporary table, memory object, or an external file really
depends on your hardware and extent of the data.
Okay, so how exactly do you implement recurision in CF you ask? Well I'm
glad you did, let's go over that.
The first thing you always want to think of w/ recursion is How the hell am
I going to stop it? or you'll introduce all sorts of fun infinite loops
your sysadmin will just love. In this case our stop criteria is when
parent.recordcount in fig. 3 (heh, I feel so official mentioning figure
numbers) becomes 0.
// fig. 3
cfquery name=parent
SELECT cat_id, cat_name
FROM table
WHERE paren_id = attributes.cat_id
/cfquery
Okay, well that defines our stop position and at the same time shows us a
large part of our custom tag. Now let's start our thinking at the root
parent (the absolute last interation of our custom tag) and work backward.
Well we know we want to track the heirarchy, so we need to pass that parent
value to the calling tag.
caller.parent_cat = parent.cat_id;
caller.parent_name = parent.cat_name;
Okay, so that's done.. we're now down one level and we need to pass both the
root parent, and this level is a parent too. Oviously passing tons of
scalars isn't going to go over well w/ untold levels of recursion, so
instead let's move to the more formatted data structure stated before we
began.
So we have an id and name for each level of recursion. Let's save that as a
simple array:
current = listToArray(cat_id, cat_name)
That handles the last level (remeber root parent is the last tag to execute)
but we need to track as we go, so let's store these arrays in another so we
can pass them along and also keep track of the order (which is the whole
purpose). So we'll arrayAppend this (push, pop, etc. are named differently
in CF) array into our tracking one and pass it along to the previous caller.
arrayAppend(tracking, current);
caller.parents = tracking;
**[Okay. it's 5:04am and as fun as the last 10-15min writing this has
been... I have a bad cold and need my sleep. Someone else can probably
finish this off (or suggest a better solution overall). If not I'll continue
where I left off tomorrow sometime and it will probably be a lot more lucid
for it.
2 quick pointers:
1) you have to write a page to loop over every line in a select * type query
to start up the recursion.
2) that page will also deal w/ how you plan to store the info (key being
cat_id, data being the complete lineage of each cat_id
This is the extreme case of normalisation vs. perfomance :)

I agree wholeheartedly. Why log10 and not just len, other than simply the fact it counts +/- and .? Soon as a number reaches float size CF represents it internally in E notation w/ full precision. Eg. foo = 0.0424352353494; writeOutput(val(foo)); I can't say I ever do anything in CF that uses any heavy math. CF just isn't suited for it. I can't wait for CF5.0s UDFs to write function wrappers for CFXs to extend it something akin to Perl's modules for extending it's functions (haven't checked out CF5.0 other than reading a bit of the RC release notes so I could be way off on how powerful UDFs will be).

RE: cfm-resources?
You might want to move to a language such as PHP, Perl, (ick) ASP, etc. Using CF, which is really meant to be an enterprise product and costs min. $1.2k USD, might not be the solution. I realise it's often much more rapid development and has a quicker learning curve overall, but PHP and Perl are free, ASP is in the sense it can be hosted w/ chillisoft bypassing having to pay for the OS... Server such as this have lower operating costs to begin w/ so can often offer much lower rates. I'm almost sure to get flamed for suggesting something other than CF, but it's all about the right tool for the job.

Hi all, I was wondering if anyone else was having problems with free accounts at cfm-resources.com? First my password stopped working, and when I got no response to repeated emails, I gave up and signed up for another account. (Incidently, after a number of errors were thrown in the registration scripts, I ended up with three accounts but that's a different story.) Attempts to FTP in are successful after on average three or four timeouts. Everytime I do actually manage to connect, it timeouts before I can upload any files. The site itself takes ages to load and then I get server errors. The cfm-resources control panel is not even up. Now, before you tell me that you get what you pay for, I totally agree. I'm developing a site for a non-profit organisation with next to zero funding, which promotes science and technology career paths for high school students, girls in particular. The aim is to create a site that they can update and maintain themselves, thereby requiring no more funding for web work. My plan being, if I can get the site running on the free hosting service, and they see how great and easy it is and maybe interest some benefactors, I will get them to move to one of the low cost hosting services. Hell, I was even planning to pay for some of it myself. I'm not expecting great reliability or speed out of a free service. But at the moment *I* can't even view the site, and it's been like that all week. What I would like to know is, what is the reliability like on their paid accounts? I'd be reluctant to risk them after my experiences with the free service. What are the other low cost hosting services out there like? Sorry to bitch but this is driving me insane!

RE: [cold_fusion] Unusual Results, help
I'm jumping into this mid-stream w/o reading through the entire history so
bear w/ me if I'm way out there.
It's a bit of a kludge but I'll often just use a for(init_expr; expr;
post_expr) {} style loop for queries if I need good control of the cursor
over multiple loops. For simplicities sake I'll use CFSCRIPT syntax to
illustrate.
for (i=1; i le outer_query.recordcount; i=i+1) {
for(j=1; j le inner_query.recordcount; j=j+1) {
outer_query.field1[i]; // on way of accesing the element
inner_query[var][j]; // another way
}
}
I'm not fond of how the cursors function (or fails to) w/ anything complex
either. And yes, I too despise silent discarding of empty elements.
As long as we're going for gripes here, valueList() and similar functions
ONLY work w/ queryname.field notation and won't accept any work arounds
inside them. Instead of being able to use queryname[var] when needing
dynamic assignment, you have to use a named var _outside_ the statement and
evaluate the string [evaluate(queryname. var)] then have that variable
interpolated. It's an evil evil slowdown if you're doing lots of things
dynamically. With the new functions of CF5 this will become an even bigger
issue and I really hope it's better in that ver. (Haven't had much time to
check out the rc)

because it doesn't work the way you a) expect it to or b)like you want it to

Subject: RE: [cold_fusion] Unusual Results, help
This has always been the behavior of CF. I can agree that it at first
glances appears to be counter intuitive, but at the same
time, any reference
to queryname.fieldname outside the context of a CFLOOP or CFOUTPUT
results in a reference to the value of the field in the first
row of the
query. The functionality is such that there is no inheritance of
references.
Well, I think you're at risk of sounding like an apologist for Allaire.
There are a couple of things that I feel need fixing in ColdFusion, and
this is one of them (the other one that springs to mind is the inability
to
optionally specify that empty list elements aren't ignored - really useful
if you are populating database tables from delimited lists).
CFOUTPUT QUERY=GetParents
*Crappy CFSET GetParents.ParentID code required here*
CFOUTPUT QUERY=GetChildren
#GetParents.ParentID# doesn't increment properly with each
iteration of the outer loop WHY NOT ALLAIRE?!?!
/CFOUTPUT
/CFOUTPUT
Since CF5 is feature complete and in RC testing, I would
seriously doubt
that a change in behavior is going to happen in this release,
or for that
matter even in NEO.
Unfortunately, I think you might be right.

RE: SELECT * Queries
The warning about wildcards (*) is due to users wanting specific fields yet returning a whole record b/c it's easier to type (which is a huge waste). If you truely do want every piece of information (and will continue to do so in the future ie. even if fields are added) then by all means that's what a wildcard is for. One thing to consider with large queries is the overhead of transmitting the statement itself, if you're getting a small record set with many fields (or a single record) your sql statement can be almost as large as the returned set. This is where stored procedures come in, Access doesn't support them but you can store the query server side and use it's views to mimic very basic sps. I never use Access if I have any choice in the matter, so for the exact syntax to do so you might want to check SWYNK out (http://www.swynk.com) whenver you have to do anything even remotely related to M$ it's a great place to start, so is MSDN (http://msdn.microsoft.com). Even with small queries executed thousands of times daily the transmission of the query can account for a large part of traffice. Without going into a lot of detail, other DBMSs (I use the term loosely in regards to Access ;) with varying degrees of sp support will also optimise/compile the query for added performance benefit. -Original Message- From: Bud [mailto:[EMAIL PROTECTED]] Sent: March 31, 2001 07:07 To: CF-Talk Subject: RE: SELECT * Queries On 3/31/01, Jonathan Lim penned: Hi Bud, My DBA told me that the * will mean more data has to be transferred from the DB server to your CF server.

I understand that if I only needed data for 10 out of 100 fields, then yes it would be quicker to name the fields. But what about when I need the entire record?

Yep, using the application scope just set a var in a struct (their id as
key, now() as value) then clean it up for all entries
dateAdd('n', -session
timeout, now()) and you'll have a pretty good idea of who's logged in
(w/in
the session timeout limit). Just make sure to lock the scope properly, you
can also do this db in the client vars if you want.

is it possible to read variables from one application from another...

thusly a separate application name, but you wanted to see who was on...
could you actually read the mainsite.appliaction.user struct from the admin

so far, i have used 5-10 min cached database queries to do this... but
wonder about the above... could have other value as well...

RE: Back-referencing after a REFind to set a variable?
Heh, you're not going to get anything so nice as Perl string handling.
cfscript
str = "foo123bar" ;
found = reFind("foo([[:digit:]]+)bar", str, 1, true) ;
sub_str = mid(str, found.pos[2], found.len[2]) ;
/cfscript
The last argument of the reFind() is 'return sub expressions', in this case
it's true. When true, the var 'found' is a struct containing two arrays: POS
is a return of all the starting positions of the expression (1 is full
string match), and LEN is an array of lenghts of the substrings matching the
POS.
Backreferencing is avail. in reReplace() though for when you want to replace
substrings.

RE: Finding the CF Administrator password
Go to the CF Admin, under 'Basic Security' is a list of tags you can disable. That's of course just the first step towards securing the server. If you're running a shared environ make sure to grab the Allaire path to disable the CF Admin undocumented tags/functions as you can do all sorts of fun stuff w/ them. There are of course thousands of other things to be done, so have fun. Just a note on template encrypting: It's scarcly worth it as the server obviously needs a fixed key (as shown below) to make it portable and has to be an easy scheme to make the template run w/o much decryption overhead.

RE: Progress bar
Expedia uses the IE specific document.readyState and a timer calling the function (Javascript). Both the initial search criteria and the "Please wait" section are on the same page. When you begin the search it hides the one part and displays the "Please wait" part. A timer is started and it periodically changes the image (for the "status bar" look) and checks the document.readyState of the loading page. When the document.readyState == 'completed' it switches over to it. It's not technically a progress bar as much as a "Please wait" page, the movement of the image is in no way tied into how far along the search is. HTML overall isn't well suited to the task, the basic premise of HTML stops any server involvement once the page is sent. Java applets, Flash, or anything else that can either maintain a persistant connection to the server or change content without a page reload are much more suited; these of course have their own drawbacks. I can think of a few work arounds that are a bit more cross-browser compliant but none of them are pretty. -Original Message- From: John Anderson [mailto:[EMAIL PROTECTED]] Sent: January 31, 2001 18:00 To: CF-Talk Subject: Progress bar Has anyone here implemented a progress bar.

RE: Windows 2000 Professional and CF Server 4.0.1
Well, I'm not much of an win person... but doesn't the installer keep a log of all system changes made? I mean, an installer can't do anything you can't do by hand. Try exporting the applicable registry tree from the NT4 system, copying any dlls required into the system directory on the 2k system, then do a straight file copy (if you need to make any reg changes for differing drives do so). I'm not sure exactly what's changed between the NT versions that would effect CF, but the system libraries may be newer and slightly (or completely) incompatible versions that effect the functionality of certain tags. If your time and lack of newer features is worth the money you might save, might as well give it a try. -Original Message- From: Jim McAtee [mailto:[EMAIL PROTECTED]] Sent: January 31, 2001 14:12 To: CF-Talk Subject: Re: Windows 2000 Professional and CF Server 4.0.1 Zac, Thanks.

For this type of interaction a java applet is the best way to go. CF is server side parser, to use it as a chat interface would require constant posting and reloading of a page... not exactly ideal. There are a whole bunch of commercial 'live rep' chat applets available and some free ones as well. http://www.humanclick.com/ -- Popular one (though I'm not overly fond of it myself) I can't find my other bookmarks for it, but a few searches should yield some good results. For some nice GPLed ones check on SourceForge.

RE: CFSCRIPT performance
CFSCRIPT gains about a 10% performance advantage (I wish I still had the source for this number, but I can't seem to find it anymore... it was a good article) and generally cleaner code if you're doing a lot of page logic; obviously it loses out on the ease of screen display to tag based though. "The problem I have with CFSCRIPT and if() is that there is no elseif()..." Actually there is, just use 'else if (expr)' with a space. The above comment is in the right vein though, CFSCRIPT just isn't very powerful. In going w/ the tag based for display they seem to have left out anything more than a meek gesture towards scripting. It's missing many tags that would be beneficial, such as; cflock, cfthrow, etc. As well, common short form syntax like 'var = (expr) ? true : false ;' or simple operators like ++, --, +=, etc. (x=x+1 gets rather annoying :) are missing. Overall though, if you're doing more than three or four lines of non-display coding, you might want to switch over to cfscript for speed and easier reading. And if you plan to work w/ objects or complex structures staying tag based is for the masochists. ;P -Original Message- From: Philip Arnold - ASP [mailto:[EMAIL PROTECTED]] Sent: January 27, 2001 11:07 To: CF-Talk Subject: RE: CFSCRIPT performance I have a question on CFSCRIPT performance. I know that it is quicker to use CFSCRIPT than to use CFSET. Is it likewise quicker to use the CFSCRIPT if() over CFIF? I have a CFIF checking that one of 14 empressions are met (13 ORs). Would it be better to use CFSCRIPT for this? This is for the security on a web site, so it needs to be efficient. CFScript is more efficient as long as you aren't just doing just a couple CFSET or CFIF The problem I have with CFSCRIPT and if() is that there is no elseif(), you have to embed things in the else part of the code, which gets very deep if you want to check loads of variations (and can't use switch, such as ranges) CF4.5.2 has faster looping in CFSCRIPT than in CFML, so that's an advantage Also, as Robert pointed out, no white-space!

RE: The real distance formula
Well, it's been quite a while since I last delved into GIS and trig but here goes. The earth does not lend itself well to simple calculations, all the below (except the last) assume a spherical earth and ignore any diffences in the terrain, elevation, roadways, etc. That said, let's look at some formulas. The formula given in the previous post [below] is a VERY UNRELIABLE way to calculate distances (and the last lat_A, lat_B should be longitude). It's based on the law of cosines for spherical trigonometry: Mathmatically it's all there but for small distances the inverse cosine gives huge room for roundoff error. In short there are much better solutions. The haversine formula is probably most used. latd = lat1 - lat2 ; lond = lon1 - lon2 ; a = (sin(latd/2)^2 + cos(lat1) * cos(lat2) * (sin(londd/2))^2 ; c = 2 * atan(sqr(a)/sqr(1-a)) ; R = 6367 ; d = R * c ; I broke the formula up into quit a few parts so you could better see what's happening: - 'land' and 'lond' are the differences in latitude and longitude respecitively - 'a' is the chord length between the points - 'R' is the accepted radius of the earth (spherical model) 6367km Feel free to make it all one line, just sub in for the variables. There are of course some caveats with this, as with any other equation. As stated before, the earth is assumed to be spherical: If your application requires greater accuracy you can vary R in respect to latitude using the eccentricity (0.08108) of the ellipsoid (earth), the equatorial radius (6379km), and the polar radius (6357km). I won't get into that, as I really don't remeber how it's done... my notes from school seem to indicate I was more interested in the brunette sitting infront of me in that class at that point... heh. Ohh.. and this equation doesn't deal well with antipodal points (ie. exact oposite side of the earth) seems it can be off by a few kilometers. If you're dealing with very local distances you might want to consider treating the earth as flat; it can actually yield more acurate results over short distances due to the assumed R. Again, not going to bother explaining this as I'm sure you can work out the math relatively easily for asimple polar coordinate system. Anyways, neat question... I've been meaning to brush up on my trig and this gave me an excuse.

Do they handle the fact that two sets of positions, with identical longitudes (east-west, right?) but different latitu des, would be a different distance? For example, two sets of positions - both the same longitude, but latitudes of several hundred miles difference - and two other positions, also the same longitude, and the same distance apart north-south as the other two. The northern set of positions would be a shorter distance apart than the southern set... does the formula deal with that? --Scott - Original Message - From: "Dylan Bromby" [EMAIL PROTECTED] To: "CF-Talk" [EMAIL PROTECTED] Sent: Saturday, January 27, 2001 4:36 PM Subject: The real distance formula A week or more ago, someone posted a formula for calculating the distance between two points using latitude/longitude.

If you want miles, do the calculation after the fact, or change the value of 6378 - the earth's radius in KM - to a value in miles. --Dylan ~~ Structure your ColdFusion code with Fusebox.

The scope="" is optional as you can use the same locking syntax as in 4.0, ie. named locks (scope and name are mutually exclusive though, so don't try both). I'm running 4.5.2 ENT (and a 4.5 Pro) (so if it's a 4.5.1 bug I wouldn't know) w/ strict attribute validation and it's working fine. I don't think Allaire would cut their own throats by being that backwards incompatible; I mean they provide deprecated functions like parameterExists() still, which is a pre 4.x function. So a cflock like this: cflock name="foobar" timeout="5" Should work the exact same in CF4.0x and 4.5.x, if it isn't I think I'd contact Allaire on the issue. Hope it helps, Raymond B.

RE: Adam, you got to be kidding?
I don't know about Adam, but you don't have to forfeit anything you mentioned: You develop w/ browser degradation in mind. So you don't use the img w/ an onclick, as it doesn't degrade (unless you use another option in addition) but the input can be used by all. Whenever you offer a fancy menu, you make sure it doesn't even show up in older browsers (unless it degrades well) and have a low profile text nav at the bottom of the page, etc. You don't have to forfeit client-side data validation at all, as if the browser doesn't have it enabled (as many embedded devices, etc.) it just isn't there to them... but the (figurative) 98% still get the benefits: and you add in server-side validation as well for those who don't (among other reasons). This of course partially depends on your target market, but the "screw those w/ old equipment or non-standard setup" mindset should be used w/ care. Now if you're doing some high profile game site, by all means go w/ only the coolest tricks as you know the platform and general computer specs of your market.

RE: ASP Code within CF Code? WAS (RE: retreiving datatypes)
Yes it looks a lot like ASP b/c it's using an ADO (ActiveX Data Object? - I
never remember that TLA... it's a COM object by another name) which is what ASP
commonly uses. So you are using the same object, and the syntax looks
superficially similar... but it is very much CF: You could do the same tag based
if you desired (though it would be much harder to read IMO). Bear in mind though
that accessing dbs in this way is much slower in both dev time and execution
time (in almost all cases) than using CFs native functions such as CFQUERY,
CFSTOREDPROC, etc.
I very rarely use M$ Access so if you have a better solution for retrieving
field design info from that dbms (I use the term loosely) then I'm all ears
(well... eyes). ;)
So while it looks a lot like ASP, it is actually CFSCRIPT code.
P.S. I'd also like to ask: When using an OLEDB connection to Access instead of
ODBC there are certain functions you can perform b/c of the interface? I'm not
much into the NT environ but, I've heard that Access dbs perform much better
under an OLEDB connection and that there is a command set that's part of the
interface?

Subject: RE: retreiving datatypes
Unlike most dbms's Access doesn't have the system tables that allow you to
retrieve table and field info though SQL statements; to my knowledge (I
avoid Access like the plague so there may be easier ways than
what follows).
Under win you can the ADODB.Connection class object and retrieve them this
way (where dsn, username, pass are vars):
cfscript
// initalise the DB object and open a connection to the desired db
dbo = createObject("COM", "ADODB.Connection") ;
dbo.Open("DSN=" dsn, username, password, -1) ;
// get schema (schema 4 is field info, 20 table info) recordset
recordset = dbo.OpenSchema(4) ;
// assign fields to "Fields" collection from returned schema
fields = recordset.Fields ;
...
The fields collection contains all the info you'll need, and can
be accessed
like this:
table_name = fields.Item("TABLE_NAME") ;
// display table current field belongs too
writeOutput(table_name.value) ;
Other valid fields in the schema recordset are; COLUMN_NAME, DATA_TYPE,
CHARACTER_MAXIMUM_LENGTH, IS_NULLABLE, COLUMN_DEFAULT, COLUMN_FLAGS, etc.
// move the cursor to the next record
recordset.MoveNext() ;
In the way above you can loop through all the data in the schema, to keep
track of it all I'd suggest using a struct. This may lots more
info than you
need, but it's the only way I know to get datatypes and other design info
from an Access table. Much, much, more difficult than simply
querying the db
as in other dbms's.

RE: Validate against a mask
You're not mistaken, it's quite far from PCREs. Generally you'll be using
posix expressions instead of the \char notation; so \d becomes [[:digits:]], \w
becomes [[:alpha:]], etc. Substrings are also quite different in the handling
(read: not nearly so nice). If you're on a dedicated server there is a CFX tag
for PCREs in CF that makes life so much easier for string parsing and data
validation. (http://www.rixsoft.com/ColdFusion/CFX/PCRegEx/cfx_pcregex.html)
Here's a link from the old CF4 manual:
http://www.allaire.com/documents/cf4/Advanced_ColdFusion_Development/04_Regular_
Expressions/adv04.htm
Also read the reFind(), and reReplace() reference carefully (not the clearest of
tech writing I know):
http://www.allaire.com/cfdocs/CFML_Language_Reference/3_ColdFusion_Functions/lr3
_200.htm
http://www.allaire.com/cfdocs/CFML_Language_Reference/3_ColdFusion_Functions/lr3
_207.htm
From the venerable Fig Leaf archives g:
(only time I've ever seen back refferencing used properly in a tutorial on CF
regexps)
http://www.figleaf.com/figleafhome/cfug/CFUGDec99/regexp/
Print refferences:
Ben Forta's "Advanced Web Application Development" by Que
List of posix character classes:
alnum - alpha-numeric characters
alpha - alphabetic characters
blank - tab and space
cntrl - control characters
digit - decimal digits
graph - all printable characters except space
lower - lower case letters
print - "printable" characters
punct - punctuation
space - whitespace characters
upper - upper case letters
xdigit- hexidecimal digits
All the standard control characters work w/in the mask, so ^ $ ? * {num,num}
etc. Sub expressions (if you set return sub expressions to true) are returned as
start postion and length in an array, and the mid() function has to be used to
retrieve them. So for basic validation CF is okay, but complex string handling
gets long and tricky compared to Perl (but nothing so annoying as string
handling in C was).
If you don't get the more advanced stuff (ie. back referencing, substring
manipulation, etc.) from the docs, I can send over some production code examples
that might help.

RE: dynamic form vars
I like using WDDX for multipart forms. You can easily serialise the entire form struct and pass it in a single hidden field (also means you're not relying on cookies or session vars). As long as every field name is unique across the multi-part form it's fast and easy. I stole a lot of this processing techinque from an article in CFDJ (Vol. 2 Issue 2 - Feb. 2000); while the article a little too gui/M$ infantile naming schemes for my taste (No offence to the author here at all, just a personal taste preference) some of its underlying principles are great. If you need it really quick and don't care much about code reuse for the moment, post directly to the second form in the series, serialise the data at the top of that form, and shove it in a hidden field. On the final page you'll then have to just WDDX the first pages results. Anyways, play w/ the concept it's very flexible and doesn't require things like cookies and sessions. -Original Message- From: Kay Smoljak [mailto:[EMAIL PROTECTED]] Sent: January 22, 2001 03:17 To: CF-Talk Subject: dynamic form vars Hi all, I'm not sure how to go about doing this.

When you do this, CF should automatically escape all single quotes. The

If you find for some reason this is not the case, you can use the replace()

RE: Selecting on dates
If you use createODBCDateTime() it will create a timestamp, which is generally the format you should use all throughout the application (or datestamp -- createODBCDate() ): Only going to other formats for display. This solves all sorts of date/time issues as it's a distinct standard format... not variable w/ peoples prefference and locale like 'dd-mm-yy', etc. I'd suggest you not use GT and the like as ANSI SQL calls for the =, , =, , =, operators, so while it may work in your current db it's not very portable. If you're worrying about the field having more precision than the passed date, don't. If you pass it in datestamp or timestamp version the dbms will work w/ it. If you create a timestamp using only .mm.dd then the time will read 00:00:00 of that day (24h clock); if you passed a datestamp and the db field had the precision of seconds, the dbms will handle it the same. In conclusion, dateFormat() should only be used when outputting to a user (or log file w/ set format). Instantly convert all date/times to a timestamp or datestamp object and use that format exclusively inside your application. You shouldn't have any date/time problems again. -Original Message- From: Paige Chandler [mailto:[EMAIL PROTECTED]] Sent: January 21, 2001 00:09 To: CF-Talk Subject: Re: Selecting on dates Hi Jim, I've used 'GT' in other Select statements successfully - but I'm not married to it.

RE: Studio and PHP?
You want killer internal PHP help support in studio? - The PHP website (http://www.php.net) supports function look-ups using a simple url get line - Studio supports internal scripting using it's object model The result should be obvious :). It's easy to add F1 support alá CF tags for PHP functions and keywords. Also you should download the HTML version of the PHP language reference and throw it into your Studio docs dir: A little bit of parsing/renaming based on the manual.html and you can quickly make it into a nicer heading style. If you like toolbars (I find moving the mouse always takes to long, so don't use them) there might be some out there for standard functions. Add in the colour coding for PHP (mentioned below), and all the other functions in Studio that make it an uber text editor and PHP support is almost as good as native CF support. Even though I work in a *nix environ, I run win4lin for Studio b/c it's such a great scripting tool (db viewer, etc. which for any interested work fine as you just setup DSNs on the local machine [emulation] for all your datasources in *nix) for web based stuff. -Original Message- From: DeVoil, Nick [mailto:[EMAIL PROTECTED]] Sent: January 19, 2001 04:22 To: CF-Talk Subject: RE: Studio and PHP?

RE: Validate against a mask
You're not mistaken, it's quite far from PCREs. Generally you'll be using
posix expressions instead of the \char notation; so \d becomes [[:digits:]],
\w becomes [[:alpha:]], etc. Substrings are also quite different in the
handling (read: not nearly so nice). If you're on a dedicated server there
is a CFX tag for PCREs in CF that makes life so much easier for string
parsing and data validation.
(http://www.rixsoft.com/ColdFusion/CFX/PCRegEx/cfx_pcregex.html)
Here's a link from the old CF4 manual:
http://www.allaire.com/documents/cf4/Advanced_ColdFusion_Development/04_Regu
lar_Expressions/adv04.htm
Also read the reFind(), and reReplace() reference carefully (not the
clearest of tech writing I know):
http://www.allaire.com/cfdocs/CFML_Language_Reference/3_ColdFusion_Functions
/lr3_200.htm
http://www.allaire.com/cfdocs/CFML_Language_Reference/3_ColdFusion_Functions
/lr3_207.htm
From the venerable Fig Leaf archives g:
(only time I've ever seen back refferencing used properly in a tutorial on
CF regexps)
http://www.figleaf.com/figleafhome/cfug/CFUGDec99/regexp/
Print refferences:
Ben Forta's "Advanced Web Application Development" by Que
List of posix character classes:
alnum - alpha-numeric characters
alpha - alphabetic characters
blank - tab and space
cntrl - control characters
digit - decimal digits
graph - all printable characters except space
lower - lower case letters
print - "printable" characters
punct - punctuation
space - whitespace characters
upper - upper case letters
xdigit- hexidecimal digits
All the standard control characters work w/in the mask, so ^ $ ? *
{num,num} etc. Sub expressions (if you set return sub expressions to true)
are returned as start postion and length in an array, and the mid() function
has to be used to retrieve them. So for basic validation CF is okay, but
complex string handling gets long and tricky compared to Perl (but nothing
so annoying as string handling in C was).
If you don't get the more advanced stuff (ie. back referencing, substring
manipulation, etc.) from the docs, I can send over some production code
examples that might help.

RE: Studio and PHP? (OT)
I don't want to start a PHP vs. CF war, so first I'll direct you to the
documentation.
CF: http://www.allaire.com/cfdocs/dochome.htm
PHP: http://www.php.net/manual/en/
What follows are opinions, please don't take offence:
I too would prefer to work in PHP, but the job market says otherwise
(unless I wanted to take a huge paycut). It's more feature plentiful in
areas such as; type casting, call by refference, call by value, better db
cursor control, objects, user functions, tons more internal functions, etc.
But because it's more feature plentiful, it suffers from higher development
times: The very fact of having more granular control, means that you _have_
to control the small details.
CFs tag based system (and not so hot cfscript) is much easier on the
display side, where PHP leans more to the scripting and display becomes
harder. Now the alternate control structure syntax in PHP can mimic the tag
based idea to a point, but overall dev times are still higher.
As always, it's pick the proper tool for the job. In no way am I banging
CF, it's great for what it is... same can be said of PHP.
(BTW if anyone doesn't know the alternate syntax and how you can sort of
mimic the CF tag based display, feel free to email outside me outside the
list or read the control structure section of the PHP manual. I find that
using the alternate syntax speeds dev time incredibly, as you're not
constantly dealing w/ printf ("vertias %s/n", $foobar): There is of course a
caveat to it.)

If you're client needs to know the exact algorythm used to generate the random method, you'll probably have to ask an Allaire programmer. CF doesn't validate the CFTOKEN anymore (as of 4.5 I think, not sure) so you can use any value you want for it; as it's just to stop people hijacking sessions by entering in a sequential CFID. If you want, you can have a UUID appended to CFTOKEN by changing the UUIDToken key in the registry to 1 (I've never done this on a system w/o a registry before so not sure where it would be stored). [HKEY_LOCAL_MACHINE\Software\Allaire\ColdFusion\CurrentVersion\Clients\] So if you're really uptight about someone guessing a 10 digit random number, either use your own algorythm to generate the CFTOKEN or concat the UUID on to the end.

I have had to write this kind of code over and over, and was wondering if
there is a better way like in c++, where it does lazy evaluation.
This is what I want:
CFIF isDefined("somevar") AND somevar IS "something"
do something
/CFIF
Of course this fails, since if the variable is not defined, CF stil
checks
the second condition. In languages like C++, it did lazy
evaluation, so if
the first condition was false, it didn't bother checking the second
condition. This let people write things like
open(FILE,"file") || die "Can't open file";
So in CF I have to rewrite my above IF statement as 2 statements
CFIF isDefined("somevar")
CFIF somevar IS "something"
do something
/CFIF
/CFIF

RE: any ideas?
IIF in an Inline IF statement, so only has boolean TRUE and FALSE (ie.
two states). If you want to vary between more use a switch/case setup again
dependent on the mod and rowcount. The nicest thing about the iif() is it's
inline and clean looking in your code; any type of if/elseif or switch
statments are either going to be slightly removed from the line or not look
as nice... but they work.
cfscript
// determine row colour based on mod of current query row
switch (DirList.CurrentRow mod 3) {
case 0:
colour = "e7" ;
break;
case 1:
colour = "fafafa" ;
break;
case 2:
colour = "a1a1a1" ;
break;
}
/cfscript
tr bgcolor="#colour#"
If you want gradients of a single colour you could also use mod to
generate it mathmatically, instead of a sub type operation.
tr bgcolor="0909#evaluate((DirList.CurrentRow mod 3) * 3)#9"

RE: Session age?
You could always set a session var w/ the current date and have a not
isDefined() making sure it isn't overwritten.
cfif not isDefined("session.created_at")
cflock scope="session" type="exclusive" timeout=2
cfset session.created_at = now()
/cflock
/cfif
If this was thrown into the Application.cfm you'd have a created_at var
initialised w/ the session and valid until it expires. I'm not aware that CF
tracks the absolute creation time, but it might be some undocumented var
(it's not in the session scope if you loop through the struct though).

Merry Meet Jon,
The way that I understand session variables to work you can't tell when the
var was originally set on the users machine because that time stamp is reset
everytime they access a new page. If it wasn't updated with the current
time then the user would timeout even if they weren't done with your site.
Blessed Be,

RE: retreiving datatypes
Unlike most dbms's Access doesn't have the system tables that allow you to
retrieve table and field info though SQL statements; to my knowledge (I
avoid Access like the plague so there may be easier ways than what follows).
Under win you can the ADODB.Connection class object and retrieve them this
way (where dsn, username, pass are vars):
cfscript
// initalise the DB object and open a connection to the desired db
dbo = createObject("COM", "ADODB.Connection") ;
dbo.Open("DSN=" dsn, username, password, -1) ;
// get schema (schema 4 is field info, 20 table info) recordset
recordset = dbo.OpenSchema(4) ;
// assign fields to "Fields" collection from returned schema
fields = recordset.Fields ;
...
The fields collection contains all the info you'll need, and can be accessed
like this:
table_name = fields.Item("TABLE_NAME") ;
// display table current field belongs too
writeOutput(table_name.value) ;
Other valid fields in the schema recordset are; COLUMN_NAME, DATA_TYPE,
CHARACTER_MAXIMUM_LENGTH, IS_NULLABLE, COLUMN_DEFAULT, COLUMN_FLAGS, etc.
// move the cursor to the next record
recordset.MoveNext() ;
In the way above you can loop through all the data in the schema, to keep
track of it all I'd suggest using a struct. This may lots more info than you
need, but it's the only way I know to get datatypes and other design info
from an Access table. Much, much, more difficult than simply querying the db
as in other dbms's.

Subject: retreiving datatypes
I know that I can build a list of column names in an Accrss table with the
columnlist variable, but is there also a way I can do the same thing in
order to retrieve the corresponding datatypes for all the fields in an
Access table?

RE: Validate against a mask
Not sure if you've ever used regexps, but that is what you want. Check out
reFind() and the other regexp functions.

Is there a way to validate against a mask like lets say in MS Access. Is
there a CF function that does this?
Something like
ConformsToMask("mm-dd-","01-17-2001")
or
ConformsToMask("###-###-","111-111-")

RE: Validate against a mask
Oh just to tack on an added note, you'll probably want to do it client side
first in JS (which has even better regexp support). Netscape Dev area and
others have great articles on JS regexps wether you're coming over from Perl
and just need the differences outlined, or completely new to the entire
concept.

RE: Dynamic Variable Names
You're trouble is you're not using the evaluate() function (and you're
using # gratuitously :).
cfset varname = evaluate("form.id" x)
This will now be the value of from.id1 instead of the string "form.id1"
(through whatever). There are other ways to handle this as well.
One thing of note is instead of using the for style cfloop, use a while
(conditional) loop and you won't have to pass the number along, just add a
counter.
cfset x = 1
cfloop condition="isDefined('form.id' x)"
cfset varname = evaluate("form.id" x)
cfif varname is "Custom"
!--- do this if custom ---
cfelse
!--- do this if NOT ---
/cfif
cfset x = x + 1
/cfloop
This will now run from x to the first break in the ints up from it; so 1
until whatever you decide w/o you having to pass a number.
Alternately, if it's all logic you might want to use cfscript.
cfscript
x = 1;
while (isDefined("form.id" x)) {
field = evaluate("form.id" x) ;
if (field eq "Custom") {
// do this is custom
} else {
// do this if not
}
x = x + 1 ;
}
cfscript

Subject: Dynamic Variable Names
Hi,
In this example I have two pages...with a form post inbetween.
The first page has a lot of text boxes called ID1 to ID16 (so, 16 in total
;) ).these boxes are in a database loop (thus the number to
differentiate them). Also over time the number may change from 16 to 18
etc..so there may be more text boxes.
I also pass this total number (16) to the second page in a hidden field.
On the second page I want to evaluate the value for each one..but as the
total number is not a constant I need to do a loop.
The following code is what I have come up with :
cfoutput
cfloop from="1" to="#Form.TotalEvents#" index="i"
#I#
cfset varname ="Form.ID#i#"
cfif #varname# eq "Custom"#varname# = Custom/cfifbr
/cfloop
/cfoutput
..end code.
What this is SUPPOSED to be doing is checking if the passed VALUE for
Form.ID1 (through 16) equals "Custom", and if so it does something, else
something else...
.but what it is doing is a literal comparison, so there are NEVER any
true
results to the if statement, when infact with my current code 11 out of 12
should return true.
Can someone help me with this...it may be trivial to some of you..but I need
to get around this ASAP.
Thanks heaps!!!
