Re: isDefined Equivalent for an Array
what about using: test_index lte arraylen(myarray) - Original Message - From: Raymond Camden [EMAIL PROTECTED] Date: Wed, 4 Aug 2004 13:42:39 -0500 Subject: Re: isDefined Equivalent for an Array To: CF-Talk [EMAIL PROTECTED] Um, no. The second attribute to isArray checks to see if the variable is an array in that particular dimension. There is no built-in way to see if an array element is defined. You can , however, use a simple UDF. CFLib has one.

RE: cftry cfcatch/cfcatch/cftry (the solution)
Ok, you wanted a hint, here's big a hint. Obviously, the advantage to using a global CFTRY/CFCATCH is that variables are still scoped in the exception block, unlike the global exception handler. The open and close cftry (as you said) must be in the same template, the solutions is surprisingly simple. I've implemented the following code in pre 4.5 systems, and it's worked great: In the Application.cfm: cftry cfinclude template="#cgi.script_name#" cfabort cfcatch type="ALL" cfinclude tempalte="myexceptionhandler.cfm" /cfcatch /cftry This code includes the requested template, so you turn the normal execution thread a little inside-out. But it works. The only thing I've found that doesn't work with it (since you actually NEVER leave the Application.cfm), is ColdFusion's built in server-side form handling (where you do HIDDEN Name="FORMFIELD_REQUIRED"). The nice thing is that it's global and retrofits to any existing code. -Original Message- From: Neil H. [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 13, 2000 8:38 AM To: CF-Talk Subject: cftry cfcatch/cfcatch/cftry I just found, disappointingly enough that you can't have a cftry at the top of a document via a CFinclude and the rest in another include at the bottom? Is there a work around. I don't want to use a handler, and I want the same error checking code on every page. Please advise or throw ideas (even bones will do) Thanks, Neil p.s.

We just use CF to pass the parameters to Crystal, and the CR Web Server to display the reports. That works well for us.

help returning record sets from PL/SQL
Can Anyone give me guidance on how to return record sets (ideally multiple) from PL/SQL using CFSTOREDPROC. I've got no problem using CFSTOREDPROC, it's the PL/SQL syntax I haven't found documentation on. It's real simple in SQL Server, but I haven't been able to do it in Oracle. Any help is appreciated.

RE: cfscript rules of thumb: loop performance
On a performance note, the loop constructs in CFSCRIPT are considerably
slower (take 5 times longer in some cases) than the CFLOOP counterpart.
This is due to increased flexibility with the cfscript versions. If you're,
for example, doing a standard for loop, it's usually much faster to use a
CFLOOP with a CFSCRIPT tag within it.
You can test different scenarios by using gettickcount() and doing very
large loops. Try this code for fun:
cfscript
time = gettickcount();
for(i=1; i lt 10; i=i+1)
{
WriteOutput("");
}
time = gettickcount() - time;
writeoutput(time);
/cfscript
cfset time = gettickcount()
cfloop from="1" to="10" index="i"
cfoutput/cfoutput
/cfloop
cfset time = gettickcount() - time
cfoutput: #time#/cfoutput

Subject: cfscript rules of thumb
Ok, I went ahead and have started using CFSCRIPT and I'm loving it so far.
I was wondering if anybody could give me some CFSCRIPT tips, rule of thumb,
best practice type advice. I've got alot of old code that I want to go back
and trim up, but I want to make sure that I use CFSCRIPT in the best place,
and take advantage of it.
