Hi I have a problem when creating a CPropertySheet and CPropertyPage.When I run my program both debug or release mode I get an error First-chance exception at 0x773d7901 in PYDVR.exe: 0xC0000005: Access violation writing location 0x004739ec the error is generated after i call DoModal() and is generated in the file dlgprob.cpp line 931 HWND hWnd = (HWND)::AfxPropertySheet(&m_psh); The strange thing is it dosnt cause the application to fail and the property pages work fine even if i run the release version there is no crash. I tried the three ms samples CmnCtrl1 and Cmnctrl2 both do not cause the same error but running Cmnctrl3 example the same error happens I am using vs2010. Has anyone come accross this error? I don't think its my code as I have basically copyied the ms sample.

Hi nchannon,

first-chance exception may occur in some cases without being caused by a bug - here's a short article about what first-chance exceptions are: http://support.microsoft.com/kb/105675/en-us

In short words a first-chance exception is shown by the debugger as soon as the exception occurs but before the program probably handled it. The second-chance exception is thrown if such a first-chance exception isn't handled by the application.

Of course it would be good to know the reason because it could be an indication for an error in your code - check the debug output if there's someting strange. Maybe going through the code with the debugger may even give you a hint what's the cause.

Hope that helps,

ZOPPO

Thanks Zoppo at least I can ignore the first-chance exception as it only happens the once still I think it must be a bug between XP and WIN7 as it is fine when you debug under WIN7 only throws the exception under XP.
