I need to get the file to open though the common Open File dialog box, so I have
the following with my headers:
#pragma comment(lib, "comdlg32")
Then theres a function called from WM_COMMAND in WndProc like this:
if(LOWORD(wParam)==1003) { openExistingFile(hwnd); }
And the function looks like this:
int openExistingFile(HWND hwnd) {
OPENFILENAME ofn;

ofn.lStructSize = sizeof(OPENFILENAME);
ofn.hInstance = hMainInstance;
ofn.hwndOwner = hwnd;
ofn.Flags = OFN_FILEMUSTEXIST;
if(GetOpenFileName(&ofn)) { return 1; };

return 0;
}
hwnd is of course the hwnd parameter for WndProc, and hMainInstance is the
hIstance with which the main window was created.  It all compiles fine, but when
I select the appropriate item from the menu the programme closes.  There are no
error messages or such.  Any suggestions?

memset ( &ofn, 0, sizeof ( ofn ) );  // Might solve the problem.

maybe you should do something more than a return otherwise it is normal that it does nothing
