First-chance exception in <program.exe> (Comctl32.

   Hi XTP programers
If I select customize (ribbon bar) than everytime I get a first chance exception.

During analysation the problem, I found this article:
http://support.microsoft.com/kb/158552/en-us

A look into MSDN for PROPSHEETPAGE Structure confirme the problem.

pResource
Pointer to a dialog box template in memory. The PropertySheet function assumes that the template is not write-protected. A read-only template will cause an exception in some versions of Windows.

The exception doesn't raised if the current font (CDialogTemplate) and the actual font of the property sheet dialog is not equal. So the function
_AfxChangePropPageFont(pTemplate, bWizard);
in method CPropertyPage::PreProcessPageTemplate(PROPSHEETPAGE& psp, BOOL bWizard) makes a writeable copy of the dialog resource.

This class also free the global memory object at termination.

To resolve the problem I would like to subclass CXTPRibbonCustomizeQuickAccessPage and overwrite the method PreProcessPageTemplate
to create always a copy. But the problem is, that
a) this work have to do for every page
b) 2 pages/objects already created in CXTPCustomizeSheet

Make it sense to modify your classes and create a copy at default?

Best regards
Michael Sabo

	That's right. But it would be nice if no exception is raised and it is possible to suppress the exception. So the exception don't confuse for someone who don't know about this problem (as I before). Michael
