如果是基于对话框的程序在APP类的InitInstance函数中的:
CDialogTestDlg dlg;
m_pMainWnd = &dlg;
////在这里Create另一个对话框。
int nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
// TODO: Place code here to handle when the dialog is
// dismissed with OK
}
else if (nResponse == IDCANCEL)
{
// TODO: Place code here to handle when the dialog is
// dismissed with Cancel
}
// Since the dialog has been closed, return FALSE so that we exit the
// application, rather than start the application's message pump.
return FALSE;
