how could I disable Escape the dialog

[lonely_life]

how could I disable the function when I click escape, dialog auto close. just like overwrite OnOk() function? but it seems there's no OnEscape()

The function you are looking for is OnCancel. Add a button with the ID IDCANCEL if you don't already have one, double click it to create a handler (in MSVC++ 6.0). Remove the call to the base class OnCancel and - finally - remove the button if you don't need it (although of course not the handler :-))

hmmm, if I overwrite OnCancel function, Esc key terminating the application is disabled, but I also can't terminate the application by click the top right cross button. What I want is just disable the key meanwhile the cross button still works.

Then you might want to kill the keypress as early as possible, adding the virtual function PreTranslateMessage:

BOOL CSomeDlg::PreTranslateMessage(MSG* pMsg)
{

BOOL result = FALSE:
if( pMsg->message == WM\_KEYDOWN && pMsg->wParam == VK\_ESCAPE )
	result = TRUE;
else
	result = CDialog::PreTranslateMessage(pMsg);

return result;

}
