This is a plea for help!! I am trying to subclass a modeless dialog box with a private window class in the aim of giving an icon when minimising the dialog box. Everything compiles, and the Window function for the dialog box is called with a WM_NCCREATE message but crashes with an Unrecoverable Application Error when executing the DefDlgProc function. Does anyone have any suggestions as I am fresh out of ideas. I have checked the obvious possibilities - the Dialog function is exported - the dialog template has the correct CLASS line - hInst and hWnd parameters to CreateDialog are initialised If noone has any guesses as to the problem, is there another way in which I can give the dialog box an icon ? Thanks in advance, Gary Hill, gjh87@uk.ac.soton.ecs

OK, ignore the previous message, I've fixed the problem.
For anyone whose interested, the cbWndExtra field in the
WNDCLASS structure should be set to DLGWINDOWEXTRA for window classes
designed for dialog boxes.
Sorry if I wasted anyones time.
