RE:CFX_IMageInfo leaving directory in use?

Hello.

Been rather busy of late so didn't seen your post till now. Sorry. But that's also the thing I love most about open source -- sometimes problems can fix themselves (sort of).

Anyway, will fix the bug in the version downloadable on this site and add you the credits (like I do everyone that posts a bug fix.)

Thanks. Sorry about the hassle though.

CFX_IMageInfo leaving directory in use?

From: Steve Hammonds

I have a template that loops over a directory structure and uses CFX_IMageInfo to retrieve information for the images in the directory. If the image height is greater than the width I cfexecute to irfanview and rotate the image. Then I move the file using cffile and delete the directory.

The problem is that I can`t delete the directory after it has been emptied, even manually. I get a sharing violation and I am told that the directory is in use. I have commented out portions of my code and am left to conclude that CFX_ImageINfo is somehow causing Cold Fusion to leave the directory in use. Restarting CF releases the directory and I can delete it. I checked CF administrator and I am am NOT keeping the CFX_IMageInfo library loaded.

We are running CF 4.5 and the server is Windows 2000 with IIS.

Any tips, comments??

Here`s some code that can reproduce the problem:

Code:

<cfset rootdir=`d:cfusiontemplatecfproequipmentdrawingstestroot2`>
<cfset movedir=`d:cfusiontemplatecfproequipmentdrawingstestdest`>
<cfdirectory action=`list` name=`thefolders` directory=`#rootdir#`>
<cfdump var=`#thefolders#`>
<cfloop query=`thefolders`>
<cfif not comparenocase(type,`dir`) and comparenocase(name,`.`) and comparenocase(name,`..`)>

<CFX_ImageInfo folder=`#rootdir##name#` filter=`*.tif`>
<cfdump var=`#imageinfo#`>
<cfif len(imageinfoerror) is 0>
<cfset dirname=name>
<cfloop query=`imageinfo`>
<cffile action=`MOVE` source=`#rootdir##dirname##file#` destination=`#movedir##file#`>
</cfloop>
<cfdirectory action=`delete` directory=`#rootdir##name#`>
</cfif>
</cfif>
</cfloop>

Fixed it!

The source code was graciously included with the custom tag. In the request.cpp file you make a call to ImageInfo. ImageInfo declares a HANDLE called hFolder that never gets released. I added `FindClose(hFolder);` to the end of ImageInfo function and recompiled. I had to restart the cold Fusion server for it to recognize the new dll file but the problem is solved!
