Programming Tips - Why is my MFC program asserting at line 246 of winocc.cpp ?

Date: 2010jan18 Language: C/C++ Framework: MFC OS: Windows Q. Why is my MFC program asserting at line 246 of winocc.cpp ? A. You probably forgot to call:
CDialog::OnInitDialog();
at the start of your class's OnInitDialog() method. It should look like this:
BOOL CMyDlg::OnInitDialog() { CDialog::OnInitDialog(); // ... Do your stuff ... return TRUE; }
Declared in the .h file as:
virtual BOOL OnInitDialog();
