me.hWnd valid at program shut down?

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

Thanks again

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
