Assert error when using CFileDialog Constructor

[torbjorn]

Hi,

I have the following line in one of my C++ functions:

CFileDialog fileDlg( FALSE, "prg", "program.prg", OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, "Program (*.prg)|*.prg||", NULL);

I get the error message as seen in the attached file.

I include the following files:
#include "afxwin.h"
#include "afxdlgs.h"
#include "atlbase.h"

and everything compiles and runs fine, except for the fact that I get an assert error when getting to the line using CFileDialog.

What might be the problem?

Thanks,
Torbjørn

Are you creating the CFileDialog on the stack or heap? It should be created on the heap as all MFC Classes should except for those like CString, because CString does not represend a window in anyway.

That line of code by itself isn't causing the assertion (thrown by AfxGetResourceHandle()). It has to be caused by something else that happens before you create the file dialog object. At least that's the way it looks to me.

Did you jump into the debugger ? What did it tell you ?
