Manipulate the DPI with cfimage?
Hello, i use a Linux Server with CF8 an want to read out or manipulate the dpi of pictures with cfimage. I have found it only in the function ImageGetEXIFMetaData, but not every picture have the Exif Data. Is it right, that this function is not supported in CF8? Thanks!

RE: Manipulate the DPI with cfimage?
When you're dealing with images for display on computer screens, there's really no such thing as dpi. It all has to do with the pixel dimensions. If you have a 1600x1200 image, then it would be 22in x 16in at 72dpi (on a monitor) or 5in x 4in at 300dpi. -Original Message- From: Carsten Klement [mailto:[EMAIL PROTECTED] Sent: Thursday, January 03, 2008 8:02 AM To: CF-Talk Subject: Manipulate the DPI with cfimage?

RE: mssql pagination
Jonathon, Here's a stored procedure you can use in MSSQL 2k for pagination: http://blog.pengoworks.com/index.cfm/2006/6/19/MSSQL-2k-Stored-Procedure-for -Pagination It doesn't use #temp tables and it will only return the pages of data you're after. I've used it on tables with several millions of records and had great success with it. Also, in SQL Server 2005 you can solve this problem with Common Table Expressions (CTE) -Dan -Original Message- From: Jonathon Stierman [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 02, 2008 6:01 PM To: CF-Talk Subject: mssql pagination I can't imagine I'm the first person to try to do something like this, so hopefully you guys can give me some insight! I know this isn't strictly CF-related -- but I'm hoping some of you have tried to do something like this in the past. I'm trying to produce a paginated list of records. The query I'm working with has about 2 rows, and I'd rather not force the user to sift through all those pages in a single page request. So I'd like to break it up, maybe display 50 records per page. I'd also prefer not to have the full query sitting in memory every request. If I'm only displaying rows 50-100, I only want rows 50-100 in the query object. Using cfloop with startrow and maxrows won't cut it this time. Apparently this is super easy in MYSQL using the LIMIT (records), (offset) clause. Turns in MSSQL makes things difficult. A couple sites I hit up showed examples of using of subqueries and the TOP filter, or (ugh) temporary tables. I went with the subquery/TOP approach. For example, ordering by dateAdded and wanting to show rows 20-30: SELECT TOP 10 sampleID FROM Samples WHERE 0=0 AND sampleID NOT IN ( SELECT TOP 20 sampleID FROM Samples ORDER BY Samples.dateAdded ) ORDER BY Samples.dateAdded Grab the first 10 records after eliminating the first 20 records, always sorting by dateAdded. But I found it worked sporadically. Pages 1 and 2 worked fine, displaying the 1-10 and 11-20 records respectively. But page 3 gave me some strange results. It showed records 14-23 or some other mismatch. Obviously not what I was looking for! After some investigation, I found out my subquery was not returning the right samples to exlude. What I haven't been able to figure out is *why* they are not returning the right subset. As far as I can tell, the SQL looks good to me. So my question to you guys is -- 1. Can you see anything wrong with how I've set up my Query? 2. How have you dealt with pagination in the past? Is there an easier route than what I'm taking now? PS -- I am running on MSSQL Server 2000 (I have heard they offer an OFFSET clause in 2005, but sadly, I do not have access to that). If anyone is interested in seeing some sample data of what I'm working on, I put up this HTML page: http://www.vimm.com/developerTools/sampledata.html You can see in the All Samples section that records 20-30 should be: [147, 148, 149, 150, 63, 36, 40, 382, 383, 384]. But the Total Wrapper query returns: [146, 147, 148, 149, 150, 63, 382, 383, 384, 440]. What happened to record 40? It's row #27 in the All Samples query, but it's included in the exclude Nested Subquery that should only be pulling the top 20 results. How does that happen?

I've argued many times myself (as author of ImageCFC) that DPI is not a function of the image itself, but the meta-data of the image, as the DPI is *ONLY* used for print. So unless you're using Coldfusion to send a file to the printer after manipulating the dpi, there's no point. that being said.. if you've got a jpeg that has the meta data for DPI, you could theoretically change the metadata to say that the image is 300 dpi, and when you open it in photoshop, it would be 300 dpi. But as was said, the DPI has nothing to do with the image itself, so if you've got an image with no meta data, you'd have to first convert it to a format that supported image metadata, add thei mage metadata and set the DPI. -- Rick Root Coldfusion/Flex Developer needed in Durham, full-time, no telecommuters.

it should only return enteries with a trailing space..

create table testtbl ( name varchar2(10));
insert into testtbl values ('Greg ');
insert into testtbl values ('Greg M');
insert into testtbl values ('Greg Mo');
insert into testtbl values ('Gary ');
insert into testtbl values ('Ghetto Fab');
commit;
select * from testtbl where name like '% '
returns only
NAME
'Greg '
'Gary '
(I added quotes so you can see the trailing space)

Re: sql question: contains space' '
You may need to get into database character functions. I believe they all have them, but they all implement them slightly differently. You will need to consult appropriate documentation for you database management system. But you should be able to do something like this concept. SELECT fields FROM aTable WHERE right(aField, 1) = ' ' I.E. Select records where the last character of a field is a space. The purpose of the LIKE operator is to search the entire field for a match, and that is not really what you want.

Well, I'm content chair for cf.Objective() so I may be a little biased (but I'm also on the advisory board for CFUNITED)... cf.Objective() is designed to be different from CFUNITED. CFUNITED has long established itself as the biggest ColdFusion-focused event in the world. It has the most attendees (over 900 in 2007), the most speakers, the most tracks, the most sessions and covers the broadest possible range of topics that might interest CFers. It has a lot of sponsors and exhibitors. It has something for everyone, from a full-on bootcamp to frameworks and advanced stuff and it even has non-CF topics that CFers might find interesting such as a track on management stuff. CFUNITED has also traditionally had New Atlanta and Microsoft as sponsors - and speakers - adding to the variety. http://cfunited.com/go/topics cf.Objective() is smaller (100 attendees in 2006, 200 attendees in 2007 and we're hoping for 400 in 2008 - a number we probably won't exceed in future years in order to maintain the small conference feel and the ease of networking). cf.Objective() has always been focused just on advanced ColdFusion topics and frameworks, with an emphasis on Adobe ColdFusion. For example, in 2007 it was *the* conference to learn about the new features in ColdFusion 8 before its release. This year cf.Objective() has formal tracks, including an RIA track (that is still mostly focused on ColdFusion). There are also some two hour in-depth sessions, three of which are going to be hands on (Advanced ColdBox, Advanced ColdSpring, Agile Development). http://cfobjective.com/sessions.cfm Is there overlap between the two conferences?

RE: 2008 conferences of interest
Thanks for the feedback Shawn. I've put in my request for either WebManiacs or CFObjective. CFObjective because it does have a lot to offer for more advanced developers. WebManiacs because what it offers for the price is too good to pass up. andy -Original Message- From: Sean Corfield [mailto:[EMAIL PROTECTED] Sent: Thursday, January 03, 2008 10:29 AM To: CF-Talk Subject: Re: 2008 conferences of interest On Jan 2, 2008 6:27 AM, Andy Matthews [EMAIL PROTECTED] wrote: I'm really leaning towards this one. I've heard that it's a little more in-depth than CFUnited is. Can anyone confirm this? Well, I'm content chair for cf.Objective() so I may be a little biased (but I'm also on the advisory board for CFUNITED)... cf.Objective() is designed to be different from CFUNITED. CFUNITED has long established itself as the biggest ColdFusion-focused event in the world. It has the most attendees (over 900 in 2007), the most speakers, the most tracks, the most sessions and covers the broadest possible range of topics that might interest CFers. It has a lot of sponsors and exhibitors. It has something for everyone, from a full-on bootcamp to frameworks and advanced stuff and it even has non-CF topics that CFers might find interesting such as a track on management stuff. CFUNITED has also traditionally had New Atlanta and Microsoft as sponsors - and speakers - adding to the variety. http://cfunited.com/go/topics cf.Objective() is smaller (100 attendees in 2006, 200 attendees in 2007 and we're hoping for 400 in 2008 - a number we probably won't exceed in future years in order to maintain the small conference feel and the ease of networking). cf.Objective() has always been focused just on advanced ColdFusion topics and frameworks, with an emphasis on Adobe ColdFusion. For example, in 2007 it was *the* conference to learn about the new features in ColdFusion 8 before its release. This year cf.Objective() has formal tracks, including an RIA track (that is still mostly focused on ColdFusion). There are also some two hour in-depth sessions, three of which are going to be hands on (Advanced ColdBox, Advanced ColdSpring, Agile Development). http://cfobjective.com/sessions.cfm Is there overlap between the two conferences?

RE: Manipulate the DPI with cfimage?
Mark... You're also confusing image quality (compression) with DPI (or pixel dimensions). At it's heart, a bitmapped (or raster) image, is simply a series of 1 pixels blocks with specific color assignments. An image doesn't know what quality (compression) it is. It also doesn't know what resolution it is. The only thing an image knows about itself, is how many pixels it is comprised of, and what specific color each of those pixels are. I think Claude's usage of the term density is an excellent choice. DPI simply indicates how many pixels are crammed into your unit of measure. If you REALLY want to start bending your head you'd start talking LPI (lines per inch), or linescreen. That's usually a better measure of print quality than is DPI. Bit depth simply refers to the total number of colors available to an image. -Original Message- From: Mark Kruger [mailto:[EMAIL PROTECTED] Sent: Thursday, January 03, 2008 11:06 AM To: CF-Talk Subject: RE: Manipulate the DPI with cfimage?

Re: Manipulate the DPI with cfimage?
Visually DPI represents dots per inch - it's a measure of density in printing. The higher the DPI the better the quality of printing - right? Exact. It's a density. The definition of a resolution is the size of the smallest element the instrument can measure, -- if the instrument sees or measures things -- or generate, if the instrument creates things. It is closely related to the density, of course, but it is not formerly the same thing. Thus, the unit of resolution for instruments like printers, monitors or scanners would be in inches, or 1/1000 In. For instance, a printer with a density of 1000 DPI has a density of 1/1000 In. Note that on some optical instruments like cameras, or human eye, the resolution is measured in angle units. The human eye has a resolution of about 1 minute angle. On a monitor the pixel is in one way a measurement of size - as in how many pixels can I get on the screen. Ok, now how many pixels, this is called the definition. This is the maximum number of different elements the instrument can measure or genrate (ie: lines in TV transmission) Of course, the more pixels you have to represent an image, the better the quality will be. Note that: density = definition / size of the working area resolution = size of the working area / definition then density = 1 / resolution When I look at an image in Fireworks I get a measurement of pixels at the bottom - 800 by 600 for example - 96 pixels per inch. That's a size measurement. For the pixels, yes, but one should never should forget that it is a virtual image. Normally, a virtual object has no size. Now, if you make a physical representation of your virtual image, it becomes a real image, and its size will be nb.pixels * resolution of the printer, or nb.pixels / density of the printer. Talking of pixels per inch in a virtual image just does not make sense. Where are the inches we are talking about ? This setting (as I understand it) is really related to the lossy compression that is used and dictates how aggressively the file is to be compressed. Exact, and it has nothing to do with pixels, or density. But this is where non-imagy folks like me get confused. I DPI is not the same as resolution what is the proper term? In my book it is density. Is it bit depth or the number of colors used or what. Yes, it is the numbers of bits used to express color, thus the magnitude of the numbers that can be used to express the color. Then one should finally call it the color definition. How do you reference the quality of the image on the screen without using the word resolution? And if resolution IS the proper term for the quality of an image, then doesn't it have at least some correlation to DPI? You cannot express the quality in DPI or any other kind of unit. The quality depends on many factors like the pixel definition, the color definition, the compression level the precision and fidelity of the display or printing equipment, and finally, the quality of your own eye ! The overall quality is a chain of elements, DPI is only one of them. I need education on this point. What is the proper way of referring to the quality of a digital image? There is no really a unit to measure quality, one only can take in account the quality of each element in the chain. Just like in a old analogic sound equipment, the overall quality depends on many element, from the musical instrument to the auditor's ear, including the recording system, the vinyl record pressing, the piezzo pick-up, the speaker system, etc. -- ___ REUSE CODE!

I think Claude's usage of the term density is an excellent choice. Humbly, it's not really my choice, this is the way I learned it when I was student in physics.

Re: Manipulate the DPI with cfimage?
Ok So compression is the best measure of quality? except that it is a reverse measure: the higher the compression is, the lower the quality. Some softwares use % compression, some others % in quality. A 10% compressed image is equivalent to a 90% quality, etc. -- ___ REUSE CODE!

Struct Issue
I have a CFC which returns a query based listing of error messages. Here
is the CFC:
cffunction name=getMessage access=public description=Returns
either a structure containing all system messages, or an array
containing one or more messages corresponding to the messageID passed in
from the system messages structure
cfargument name=messageID type=string required=false
default=
!--- Return all messages ---
cfif messageID eq or messageID eq all
cfreturn session.systemMessageStruct
cfelse
!--- Return messages based on incoming argument ---
cfquery name=variables.qMessages dbtype=query
select * from session.systemMessageStruct where
message_id = '#arguments.messageID#'
/cfquery
cfreturn variables.qMessages
/cfif
/cffunction
Here is the call to the getMessages function: (Yes it is set as an
object)
cfset messageStruct =
application.msgMgr.getMessage(attributes.messageId)
Now I can check it this way but at times it returns an error on the
initial startup:
cfif messageStruct.recordcount
... blah blah
/cfif
Here is the error returned:
---
You have attempted to dereference a scalar variable of type class
java.lang.String as a structure with members.
TO clarify somethings:
Yes the basic structure is created as a query (dynamic query)
onApplicationStart:
cfset variables.systemMessageStruct =
queryNew('message_id,message,messageType,IconSize')
!--- Copy Dynamic Query to Session Scope ---
cfset session.systemMessageStruct = variables.systemMessageStruct
Any idea why it would return the error or a way I can prevent it? I can
not use IsStruct since it is a query rather than a true structure?

CF 4.5 MS Access Data Source Name
Flash from the past. On a CF 4.5 (Hopefully soon to be replaced) server does one need to do something special to set up an Access data source name? I'm looking at the data sources panels in the Administrator and I do not see any options for Access. I see Merant drives for dBase/FoxPro, IBM DB2/6000 Informix 7.x/9/x, Sybase 11, OpenIngres 1.s, OpenIngres 2.x Oracle 7, Oracle 8, Text and MS SQL Server. It have been a very long time since I have had to work with this version and I do not recall what has to be done to create a DSN. Is it mandatory to create a Windows ODBC entry first. I am hoping not, since I do not have access to the box, just to CF administrator through from a remote client browser session. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295774 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: CF 4.5 MS Access Data Source Name
Now that I wake up a bit and realize that this 4.5 server I am looking it is a Unix box. I probably figured out why I am not seeing the built in Microsoft Access database driver as well as that no matter how much access I have to the box, I am unlikely to find a Microsoft ODBC administration tool. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295775 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Thanks. Sometimes the query will have multiple messages to be displayed
with different messageIDs. Thus the reason I considered the dynamic
query method :-)
I will try isQuery but I think I have found that for some reason the
initial call is not creating the dynamic query itself.

Re: Struct Issue
Just a note that your method does not return a struct or an array, which is what your description attribute says. It returns a struct or a query. Also, you might want to consider refactoring this into two methods, because having it sometimes return a query and other times return a struct will probably end up causing you big headaches. Either that, or refactor it so that it always returns the same type of value (or example, an array of one or more messages).

Re: onApplicationStart
No, not really. I put all my initialization logic in a separate method of Application.cfc, and then invoke that method from onRequestStart if certain conditions are met (usually the presence of a reloadApplication URL param that is set to a specific value). Note that this doesn't expire the application, it just reinitializes it. So any pre-existing application variables will continue to exist unless your initialization explicitly overwrites or deletes them. cheers, barneyb On Jan 3, 2008 12:01 PM, Adkins, Randy [EMAIL PROTECTED] wrote: Question: When using the onApplicationStart within an Application.cfc, lets say I wanted to restart the Application to pickup some changes.

Re: onApplicationStart
You can try putting most of your OnApplicationStart code into cfinclude files and call those cfinclude file in some other reload page. This has an advantage over calling OnApplicationStart again if there are some things that OnApplicationStart does that you don't want to do a second time, such as reinitializing a list of logged-in users. If you just want to reload some application-scope variables or some cached functions, calling the entire OnApplicationStart again might be overkill. Another way to do this is to put conditionals in the OnApplicationStart block that only reinitializes certain sections depending on the input variables (commonly a URL variable). My guess is that you don't actually want to expire the application in order to reload a few variables. If you do want to expire the application, there are ways to do this. Setting the application timeout = 0 is one way. -Mike Chabot On Jan 3, 2008 3:06 PM, Brian Kotek [EMAIL PROTECTED] wrote: You can just call onApplicationStart() again, but be aware that it won't be thread safe as it is when the application starts up.

You can also temporiarly set the session timeout to 0 or some other really short time, let the application expire, then return the timeout to the desired value. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295788 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
onApplicationStart
Question: When using the onApplicationStart within an Application.cfc, lets say I wanted to restart the Application to pickup some changes. Now I know you can cycle the CF Services but I do not have that access to the server. What is another way besides creating a temp file to explicitly reset those variables?

RE: Manipulate the DPI with cfimage?
Claude, Thanks for an enlightening foray into the world of graphics. I especially like the part about a virtual object having no size..fascinating. It made me think to myself... If a virtual tree falls in the woods... (ha). In any case, excellent stuff. I feel edicated enough to be able to say now with certainty that I know next to nothing about working with graphics :) -Mark -Original Message- From: Claude Schneegans [mailto:[EMAIL PROTECTED] Visually DPI represents dots per inch - it's a measure of density in printing. The higher the DPI the better the quality of printing - right? Exact. It's a density. The definition of a resolution is the size of the smallest element the instrument can measure, -- if the instrument sees or measures things -- or generate, if the instrument creates things. It is closely related to the density, of course, but it is not formerly the same thing. Thus, the unit of resolution for instruments like printers, monitors or scanners would be in inches, or 1/1000 In. For instance, a printer with a density of 1000 DPI has a density of 1/1000 In. Note that on some optical instruments like cameras, or human eye, the resolution is measured in angle units. The human eye has a resolution of about 1 minute angle. On a monitor the pixel is in one way a measurement of size - as in how many pixels can I get on the screen. Ok, now how many pixels, this is called the definition. This is the maximum number of different elements the instrument can measure or genrate (ie: lines in TV transmission) Of course, the more pixels you have to represent an image, the better the quality will be. Note that: density = definition / size of the working area resolution = size of the working area / definition then density = 1 / resolution When I look at an image in Fireworks I get a measurement of pixels at the bottom - 800 by 600 for example - 96 pixels per inch. That's a size measurement. For the pixels, yes, but one should never should forget that it is a virtual image. Normally, a virtual object has no size. Now, if you make a physical representation of your virtual image, it becomes a real image, and its size will be nb.pixels * resolution of the printer, or nb.pixels / density of the printer. Talking of pixels per inch in a virtual image just does not make sense. Where are the inches we are talking about ? This setting (as I understand it) is really related to the lossy compression that is used and dictates how aggressively the file is to be compressed. Exact, and it has nothing to do with pixels, or density. But this is where non-imagy folks like me get confused. I DPI is not the same as resolution what is the proper term? In my book it is density. Is it bit depth or the number of colors used or what. Yes, it is the numbers of bits used to express color, thus the magnitude of the numbers that can be used to express the color. Then one should finally call it the color definition. How do you reference the quality of the image on the screen without using the word resolution? And if resolution IS the proper term for the quality of an image, then doesn't it have at least some correlation to DPI? You cannot express the quality in DPI or any other kind of unit. The quality depends on many factors like the pixel definition, the color definition, the compression level the precision and fidelity of the display or printing equipment, and finally, the quality of your own eye ! The overall quality is a chain of elements, DPI is only one of them. I need education on this point. What is the proper way of referring to the quality of a digital image? There is no really a unit to measure quality, one only can take in account the quality of each element in the chain. Just like in a old analogic sound equipment, the overall quality depends on many element, from the musical instrument to the auditor's ear, including the recording system, the vinyl record pressing, the piezzo pick-up, the speaker system, etc. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295791 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Re: PDF merge works once, then fails
Okay, I think there is a bug using cfpdfparam nested within cfpdf
action=merge. I pulled the cfpdfparams out, opting instead for a
comma-separated list in the Source attribute, and it works.
This works:
cfpdf action=merge
source=#expandPath('.')#\pdf\tmpStub.pdf,#expandPath('.')#\pdf\tmpACH.pdf
destination=#expandPath('.')#\pdf\tmpCombined.pdf overwrite=yes
Null pointer after a single iteration:
cfpdf action=merge destination=#expandPath('.')#\pdf\tmpCombined.pdf
overwrite=yes

A safer way to do that initialization is: var someVar = createObject(component,MyThing); someVar.someMethod(42); application.someVar = someVar; i.e., fully initialize the component before placing it in application scope. -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ If you're not annoying somebody, you're not really alive. -- Margaret Atwood ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295800 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Re: CF 5 and DAO
I am so use to using MX and CFCs that now I have to work on a CF5 server for a client and Is there a good way of setting up a DAO in CF5 so I can reuse SQL code and not have to retype the CFQueryies each time I need them? Should I use CFModule? CFInclude? A custom tag CF_ProductDAO? Before I offer my thoughts on the actual question, I just wanted to stop real briefly and mention, because it seemed like you got a couple responses from folks who may not have been using ColdFusion since as far back as ColdFusion 5 (or were distracted and didn't notice this was a CF5 question or remember offhand what CF5 supported). The cffunction tag was added in ColdFusion version 6. Prior to 6, versions 5 and 5.5 (iirc), UDFs couldn't include any tags because they had to be declared entirely in cfscript and there's never been any way to embed tags in cfscript. So the suggestion of using UDF's is moot (although I remember really *wanting* to do that in CF5). :) I actually had at the time created the first version of the SQL abstraction layer that's in the onTap framework on ColdFusion 5 using cfmodule. Though it was way more complicated than you likely need for your purposes. That being said, you may find it easier to use custom tags if you have access to the custom tags directory -- which in the past I had always avoided like the plague, but given that if/when you upgrade it will probably be to ColdFusion 8 where you can assign the custom tag diretory in-application, the upgrade plan then makes that transition easier. Using cf_productDAO for example would be a bit easier to find if you needed to perform a multi-file search in your code, than would be cf_module template=../productDAO.cfm. It's also fewer keystrokes, which is another bonus. If/when you upgrade, you can then rewrite the custom tags internally to use CFC-based DAO's, but in the interrim, the custom tag syntax should make your work a bit less tedious and give you a bit of flexibility to do things like sub-tags if you found yourself in a situation where you were having difficulty creating an elegant way of getting argument data into a method. I might do something like this internally within the DAO tag: cfparam name=attributes.method type=string cfset here = getDirectoryFromPath(getCurrentTemplatePath()) cfif fileExists(here productdao/ attributes.method .cfm cfinclude template=#attributes.method#.cfm /cfif cfif structKeyExists(variables,result) cfparam name=attributes.return type=string default= cfif len(trim(attributes.return)) cfset caller[attributes.return] = variables.result /cfif /cfif The idea behind this structure is to give you a consistent interface for the methods. Each method has its own template and you'll know that whatever it is you need to return goes in the variables.result variable within that template and will then be returned by the custom tag, so you don't have to keep rewriting the code that returns the result variable. anyway, that's my take, hth, ike -- s. isaac dealey ^ new epoch isn't it time for a change? ph: 503.236.3691 http://onTap.riaforge.org/blog ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295802 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Pete, I wrote a blog post a while back with a way to do this: http://jeremiahx.com/2007/08/12/how-to-email-bounce-management/ Basically you put an ID of your user inside of the failto so it would be failto=[EMAIL PROTECTED] Create a catchall on the bounces.mydomain.com domain and then parse the email address.

Re: Using message bounces to manage email list?
i do that on a site. first thing is that a lot of crystaltech's servers are on spam lists so I would check your server to see. just set up the failto address and run a scheduled task to check it and run cfpoop to check it but you need to be sure to check the header and body content for the bounces because some providers do different things. What I do is just check for email addresses and there should be 2, the one that bounced and the one that is the failto. I grab those and put them in a temp table and loop through the emails, when its done looping i compare the bounced ones with the mailing list and if there is a match it deletes it. The big problem with this though is that cfpop takes FOREVER to do this and it can time out. This site gets about 10,000 bounces every broadcast and it takes weeks to get through them, this summer we are changing it up and bought an email checker that grabs all the email addresses from that email acount and spits them out into a list then they can take the list and upload it and it will run and delete all the matches and only takes about a minutes to do it all.
