Win32 SDK dialog program problems ...

If CreateDialog itself is creating the main window of the program, how to set its third parameter?

MSDN says that this parameter is the handle of the parent window. For the main window, how should it be written?

Obviously I'm making a dialog program. This dialog is the main window. How do I set the third parameter of the CreateDialog function?

If it is the main window, only NULL is required.

Moreover, you can:
DialogBox (g_hInst, (LPCTSTR) IDD_DLGTREE, NULL, DlgTreeProc);
