Ann: CFEclipse 1.1.17 released
Hi all, The CFE team is pleased to announce the release of CFEclipse 1.1.17. Announcement: CFEclipse version 1.1.17 released 12th November, 2004 : 1000 Installation & Update Installation & update procedures are availble on the CFEclipse project website (http://cfeclipse.tigris.org) . All current non-CVS users of CFEclipse should hopefully be notified by Eclipse that there is a new release available. If not, follow the update procedures and mention it to us on the CFE lists. What's new: Around two weeks ago the CFEclipse Development team closed a feature vote, where registered users were able to vote for the features they'd like to see most. We're happy to report that due to a large amount of work by the team, 7 out of the top-ten most-voted-for features have been implemented. They are: * 11 Selected text drag 'n' drop * 138 Bracket highlighting * 17 Block indent/unindent enhancement * 183 Code folding * 21 Ctrl + Double click selects tag * 175 CFML comments * 97 CFC Browser enhancement Thanks go to Matt Cristantello for the implementation of Bracket Highlighting. For more on the new features and how to access them please visit: http://www.spike.org.uk/cfeclipse/space/start/2004-11-12/1 New features: * 201 Get the partition scanner working properly. * 174 Undo Steps * 105 Enhance code insight * --- Standard text editor prefs now in CFE page * --- Trim trailing spaces on save option available (via prefs) Bugs fixed: * 49 CFEclipse pref window resizes to fit snips directory... * 65 specifiy any attribute * 95 cfinvoke can have any argument, not reflected * 108 New CFC's are created with blank attributes * 144 syntax coluring error with <= in cfquery * 152 Error generated if CFINVOKE doesn't have closing tag * 180 Adds empty extends attribute in CFC wizard * 181 cfqueryparam (and others) breaking file parser * 182 Attribute name is not required for cfquery * 199 Content assist fails when there is a non-enclosing tag. * 200 Syntax colouring slightly off. * 205 Something preventing the closing of chevrons * 207 Tasks are being deleted by cfeclipse. * 208 CFC Methods view broken * 210 Scope insight pops up at the wrong time * 216 Error occurs when coping a large block of text * 219 Comment instide comment block renders does not show code as "commented out" The zip version of the plugin is not yet available if you wish to update manually.

Hmm, AFAIK Tortoise CVS only integrates with the Windows shell, not via the SCC API that's compatible with Visual Studio. If you want integration with HomeSite, then you'll need the Igloo CVS plugin that you can find here: http://www.jalindi.com/igloo/ Alternatively switch over to CFEclipse with Eclipse's built-in CVS support ;) I hope that helps. -- Oliver Tupman Key Systems Geotechnical [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings]
Re: new version of cfeclipse (1.1.3) the eclipse plug-in
Hello to all you CF users, If you're using CFEclipse then perhaps you might be interested in signing up at Tigris? Signing up as an observer sticks you on the CFEclipse users mailing list to join any discussion that takes place with relevance to CFEclipse. Another added benefit is that you can report bugs and make feature requests via the website which provides you with the ability to make a request and track it through all its stages of progress (so you can harass us developers when a bug isn't being fixed ;D). So if that interests you, to sign up go here: http://www.tigris.org/servlets/Join and to request to sign up as an observer then go here: http://cfeclipse.tigris.org/servlets/ProjectMembershipRequest If you're interested in doing some coding yourself, sign yourself up and then send either Rob or I an e-mail or discuss it on the CFEclipse mailing list.

Re: ColdFusion IDEs
At the moment Homesite... But I'm soon to change to Eclipse with the cfeclipse plugin once Rob or someone else (perhaps me) gets it's to maintain the function infopop until the user closes the matching ')'. Of course the advantage of using Eclipse is that you've get Rob and others that work on the plugin who will listen to your requests. Unfortunately my boss might not be impressed with this switch... he bought Homesite for me a little while ago. Oh well. Oliver Tupman.

Try this:

I may have the double quotes wrong, but that should work. MySQL receives
the date/time from Now() as an ODBC date/time string (the ones that go
{blah blah}). MySQL doesn't accept those at present, so you have to
manually format (I could be wrong, if so, someone tell me 'cos it'll
make my life easier!).
By the way, if your 'update' field is simply the time when the field is
last update (which it appears to be) and you'll never want to insert
something different, MySQL has a custom datetime type that is updated
whenever you perform an UPDATE or INSERT. Copied from the MySQL manual
is this:

Re: MySQL Aggergate
If the last post hasn't solved your problem and you're using MySQL version 4.0.2 or above, then try using the CAST() or CONVERT() function on the _expression_ that's failing. Usage I think you're looking for is: SELECT TL.T_id, CAST(MAX(dPosted) AS CHAR) as LastDaySeen You can find the MySQL manual page here: http://www.mysql.com/doc/en/Cast_Functions.html -- Oliver Tupman Key Systems Geotechnical [Todays Threads] [This Message] [Subscription] [Fast Unsubscribe] [User Settings]

If one or two queries, are you using a GROUP_CONCAT() function? If so, GROUP_CONCAT causes the server to crash or just go a tad gaga if your query returns 0 rows. Any chance of seeing the queries? Alternatively, as mentioned previously, bear in mind it's alpha software and your milage may vary.

Re: Programatically Adding Custom Tag Paths

I can't do cfmodule (I think...) because the reason I wish to do this is
to include CFCs.
For example a CFC component might live here:
oliver.fred.project.People.Present
Now I have a function New() that is simply a shortened version of
CreateComponent() that takes one argument: the component name.
I'd like to create a function called Using() that - for the duration of
the request - appends whatever is passed to it to the custom tag path.
So instead of doing this:
New("oliver.fred.project.People.Present");
New("oliver.fred.project.Car.Somethingelse");
... and so on
I could do this:
Using("oliver.fred.project");
New("People.Present");
New("Car.Somethingelse");
One way is to simply define a string that has "oliver.fred.project" and do :
New("#defStr#.People.Present");
But I'm lazy.

Programatically Adding Custom Tag Paths
Hi all, Firstly please excuse any spelling mistakes - it's nigh-on freezing here in the UK, so having ridden to work my hands are icicles. Anyway, does anyone know of a way to programmatically add/remove/modify custom tag paths. What I'm interested in doing is creating a Using() function to work in the same lines as the C#'s and Java's keyword of the same name. Ideally I'd like to update the custom tag paths for the duration of a request and no longer.

I'm assuming you're not getting the variable 'delete' set, in this case it's probably IE doing what you don't expect.

Took a look and the auth structure was present in all three pages. Tested in both IE 6 and Mozilla 1.5b. I've had an interestingly similiar on a intranet box we install recently running IIS and CF MX 6.1. When using the name of the box provided via WINS IE _always_ lost the session variables.

Re: Uniquely identifying a function
Hi all, Just thought I'd throw in a couple of thoughts into the discussion - Firstly you don't need to do 'myFuncRef.toString()' to get the java class name, just get myFuncRef, for example: Don't know if anyone's done it already, but an interesting benefit of this is that you can use them as a sort of pointers to functions. Another point is that the string you get from the function itself (i.e. [EMAIL PROTECTED]) changes with every change of that file because CF recompiles it. So if you changed the function that you're caching the data from, you'd end up with a new copy of the data for every change. If I were you, I'd use the location to the function and the function name because as mentioned earlier, it's probably going to be unique.

First the kind of project:
The project is a Quality Assurance system (bug tracking, development
requests, yadda yadda yadda) for which we are using CFCs extensively,
hence a lot of my discontent comes from dealing CFCs.
This project is 'my baby', as it were, and will remain so for the rest
of my stay at this company. It will be extended to well beyond the
current spec therefore I will have to use CF a lot.
The choice of language was not left to me so I have not looked forward
to developing the system, which only serves to exacerbate the annoyances
experienced with the language.
Now the areas. It's a long set of areas, so you may wish to skim or
avoid them at all. Once again I state that this is my own personal
opinion derived from many long hours of CF.

it. If you can help solve one or more of my problems it makes my time
with CF more pleasurable, tolerable and makes me less likely to consider
putting my hands through a cheese grater.
Problem Areas:
Object orientation (or lack thereof) and the implementation of it in CF,
performance of CFCs (found it can take 3ms to call a method!),
functions, general CFML syntax, lack of commands that are in CFML that
aren't in CFScript, sessions doing weird things (may be my fault), lack
of control (see the 'control freak').
Errrm, what else... Ah, if you put an object into the SESSION variable
it not only stores the data, but the methods associated with it as well.
Therefore change the class and it doesn't change in memory. If I could
work out how to serialize the data at the end of a request I'd do that,
but I've no idea. Instantiating an object can take ages. If CFMODULE'ing
a template that includes, say common.cfm, and the CFMODULE'ing template
also includes the same file and in that file are funcitons, then a
'function cannot be declared twice' error is raised and I can find no
way around it.
Oh, there are no equivalents to C's "#include" nor PHP's "Define()".
CFSWITCH can only take constants in it's cfcase's, therefore as you can
apparently define nothing how done one test for return values from a
CFC? By hard coding the values (though perhaps I should return strings
for error codes). Errm, CFCASE's cannot fall through to the next CFCASE
and therefore not the the DEFAULTCASE but you can do it in CFSCRIPT. One
cannot 'break out' of CFSCRIPT to CFML in the middle of a control block
(i.e. if(){}else{}).
No constructors, no true private/protected variables, CF compiles the
CFC not to a class by to a series of .class files, one for each method,
no getter/setter, you cannot define a method as fully as you can in
CFML. Oh, and you cannot call a parent method without creating an
instance of the parent class, copying over the relevant properties and
then calling the method on the parent instance and then copying back the
properties.
output="false" from a calling function applies to the called function
even if the called function does output="true".
One may say that as CFCs are a new feature then it should be
understandable that they are not well implemented and I did hope that
with 6.1 it would be somewhat solved. Nope. Being a PHP-head, I say that
objects were well implemented from 4.0 (though I would love being able
to raise exceptions like you can in CFC, oh hold on, that's in PHP 5).

Re: CF or .DotNet what do you think?
Hi Eric, Just thought I'd throw in my two pennies worth about this. I'm using CF having come from a software engineering start via PHP (which I loved). Before anyone yells at me I can see the benefits that CF gives, and two of our directors have made huge, highly reliable websites with it. [soapbox] But I do hate CF. The reason is that I'm used to the power that PHP generally gives me and I don't like the syntax. And that's just for starters. This is purely a personal opinion from a programmer, just like an opinion about your next door neighbour's new car, or the state of one's government. [/soapbox] If you decide to go the CF way, understand that quite a few of your developers may spend hours banging their heads against CF. I spend about 2 hours a day doing that. Could be because most programmers are control freaks and so like to be able to control every last detail of their application. CF takes some of that away from you of course many argue this is a good thing. Personally I'd think that VB developer could make the switch to CF relatively easily, but what one might call a 'hard-core' programmer may well have problems with the switch. In that case I'd seriously think about doing the CF + Java route, but I'd say that about the same as going a PHP + Smarty route. -- Oliver Tupman Key Systems Geotechnical ~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq This list and all House of Fusion resources hosted by CFHosting.com.

Hi all, Got a weird one: a CFM file called test.cfm gives the message: Error casting an object of type jrunx.resource.ResourceURLClassLoader to an incompatible type.

Tutorials for creating Java classes for CF
Hi all, Can anyone point me in the direction of a good tutorial of two on the creation of Java classes for use in Cold Fusion via the CreateObject() function?

Re: CFC's and how they work.
Quick note on speeding up the performance of CFCs... On a 2GHz P4 the creation of a component with CreateObject() takes (upto) 15ms. If you're using a _lot_ of objects - i.e. you're representing your system in a highly OO way - then your page times start to get realy huge. At this point you have, I think, three options - 1) Write 'em in Java. CF apparently creates Java objects with CreateObject in nigh-on 0ms. 2) Manually cache an instance of each object in the Application scope. Implement your own function - say CreateComponent() - that will get a copy of the component out of the App scope. Of course a problem with item 2 is that if you change your component then the cached copy would be out of date. I'm currently looking into a way of getting around this by using the individual IDs assigned to a class' functions. 3) If you have to make a number of instances of an object during a request, then you can implement item (2) for each request therefore eliminating the problem in item (2). -- Oliver Tupman Key Systems Geotechnical Rich Z wrote: > Thanks for the insight.

Re: Throwing exceptions from CFCs
Raymond, I still think we're not quite on the same level here. That or my MX is acting weird. I do indeed get the context, but it still comes from the , not the Throw() function. Try the following component and just call test() without any exception handling around it: SELECT * FROM table WHERE 1 Exception thrown... Notice that the error message is centered around the , not the ThrowObj() function. Also note that the message displayed has not been changed, despite the fact that I object.RootCause.Message and object.Message. It is this object I wish to modify while retaining the context.

I noticed that too, while it may partly fulfill part (b) of my original

it does not fulfill part (a)

I may of course be after too much, and expecting too much of Cold Fusion
hence my idea that I may need to delve into Java.

Throwing exceptions from CFCs
Hi all,
I'm writing a whole bunch of CFCs for our company Intranet and I've come
up on this problem time and time again:
I code a lot of my CFCs in near-pure CFScript. For some reason in CFMX,
Macromedia have provided us with the try and catch statements, but not a
throw statement/function.
As one cannot break out from the CFScript, do some CFML and then go back
into CFScript like this:
function SomeFunc(param1)
{
}
we are forced to create a Throw function that is coded in CFML so we can
do our .
This solution has problems, the biggest (for me) is the apparent fact
that any exception that occurs appears to CF to occur in our Throw()
function. This is of course due to the fact that the CFTHROW is in the
Throw() function.
If we pass an object from another exception to the CFTHROW via Throw()
the exception is displayed as having come from the correct place. This
is due to the fact that (all?) the exception(s) have an 'Exception
Context' which I think is a file/line/stack trace.
The questions are
a) how do I either modify a thrown exception that I wish to rethrow (but
with extra data)
b) how do I throw my own exceptions with an exception context?
If anyone can help here I would be very grateful. It could be a funky
Java solution, but my Java knowledge is not very great.
Cheers all,
Oliver Tupman

Re: Looping to find ONLY specific XML Children
Hey Shawn, It's just 9am here so my apologies for a short answer (or rather, the short hint) - try looking into XPath. Either do a search on Google or take a look at the XPath spec http://www.w3.org/TR/xpath A demo of the XML you're using would've been useful, but from what you've said I'm assuming it's something like this: fred http://www.somewhere.com From what I can see, get the XML into a variable then construct your XPath var, perhaps something like Then this: That should throw all of the elements that match your XPath expression into headerlinks, which will be an array. Best to read through some articles on XPath 'cos I'm sure that the above expression won't do exactly what you're after. The W3C spec is, as usual, hefty and complicated (especially at 9am!) hence the reason why I think my expression won't work properly but it should give you a pointer on where to start looking. Hope that helps somewhat, Oliver Tupman Key Systems Geotechnical. Shawn Contreras wrote: > Hello, > > I am having a problem that I desperately need help with.

Append that result with the number before the decimal point and you've got it.
