Hello
I run into a strange problem (using VB6/SP6 under WindowsVISTA, no problem under Win2000 and XP):
To retrieve special folder locations I use SHGetSpecialFolderPath(me.hwnd,...) during program execution (e.g. for the init folder of a common dialog control).
If I set a skin - all works as expected. Then I close my app - no problem. Then I restart the app - OK. Now the program part using SHGetSpecialFolder was called - and the program hung. Only rebooting the PC helps (shuting down via task manager do not cure the situation!)
If I do not use a skin it works. I think the problem has something to do with me.hwnd...
(I can not use 0 as a hwnd because - since I use IE7 - the returned path was empty and it works only using me.hwnd under XP...)
Thanks a lot for any idea

Hello
I made somed more experiments. The problem has nothing to do with setting the init directory.
As soon as we use Skins and open the open file dialog, the app hangs
If we do not use Skins, all works as expected
The problem occures only under Windows Vista (Admin, XP compatibility... doesn't matter)
The CJ SDI skin sample WORKS on all plattforms
Any idea, a solution is rel. urgent
Thanks in advance

Is it possible to remove skinning only for common controls (open file dialog)? This would be better than a crash...
Thanks again

Hi Oleg
Thats the problem. Our app is relatively large and I don't find a code snippet that shows this behaviour per se.
Our App was compiled as a ActiveX-EXE. Apart from CJ controls we use SaxBasic, Metadraw, Imageman and a few others.
It doesn't matter if the common controls ActiveX was hosted on the main form or not.
If we try to open a file open/save dialog (no problem with color dialog) and click on a file/folder the app hang. Sometimes we can choose some files but next time opening the dialog - hang. If the PC hangs it shows always the hourglass corsor.
Shuting down the app with the task manager - it is not possible to restart our app (no message - nothing); we have to reboot the PC.
Now I have set AutoApplyNewWindows to false and after opening the file open/save dialog we reset it to True. That works, but dialogs ar not skinned...
All problems where only present on the WinVista machine.
If I can try something, let me know
Thanks for any Idea

Hello Oleg
I found the problem. We use the SaxBasic ActiveX. As soon we place it on a form (without any coding) the app hang as soon as we call FileOpen of the common dialog controls (under Vista only and obly if skinned).
If it helps, I can send you the OCX (give me a mail address please). The product was discontinued by Sax, so they will not help
