Hello @all,

i found the article http://support.microsoft.com/kb/146916 !

This code i used for creating an modeless Propertysheet!

This works fine under VS6 but now i converted my code to VS10 and now the Application crashes.

I got "Unhandled exception at 0x77863f44 in ntc250.exe: 0xC000001D: Illegal Instruction." @ the function ::CallWindowProc with nMsg 295!

I also had to change the winver from 0x0400 to 0x0501 to get my code running under VS10!

Does anyone have an idea?
