Why CPropertySheetImpl::Domodal() return -1?

Question

4.00/5 (1 vote)

See more:

There is a class inherits from CPropertySheetImpl, when I do something like bellowing:

CMyPropertySheet sheet( _T("My Sheet") );
if ( IDOK == sheet.DoModal() ) {
//...
}

It works well on English Windows XP, but when it runs on a German Windows XP VM, sheet.DoModal() returns -1.
I have no idea what might cause this, anyone can help?

See the doc for PropertySheet Function[^], and notice:
For modal property sheets, the return value is as follows:
>=1 Changes were saved by the user.
0 No changes were saved by the user.
-1 An error occurred
To retrieve extended error information, call GetLastError.
