You did use the code from his WM_CREATE case just above that didn't you?  If
not, you're problem is that you haven't done a MakeProcInstance() on the
function that you intend to call.

Here's a function that I usually use to do all the dialog box stuff
encapsulated into one function.

// dialog.cpp
// tab_size: 4
#include <windows.h>

#include "winsupp.h"	// Just a prototype...

BOOL Dialog(HWND hWnd, char *szDialogName, FARPROC fpDialogProc) {
	BOOL bDBReturn;
	HANDLE hInst;
	FARPROC fpProc;
			
	hInst = GetWindowWord(hWnd, GWW_HINSTANCE);
	fpProc = MakeProcInstance(fpDialogProc, hInst);
	bDBReturn = DialogBox(hInst, szDialogName, hWnd, fpProc);
	FreeProcInstance(fpProc);
	return (bDBReturn);
}
