Because the button which is used to close the Diaolg is created by myself.


There's rarely a need to override WindowProc(). If you're using MFC,
why not just use MFC's message handling instead of doing it the Win32 way?


Regardless, your code snip is incomplete so it's not much help.

The WM_CLOSE message should be posted, not sent from your window proc.
BEGIN_MESSAGE_MAP(CSettingDlg, CDialog)
	ON_BN_CLICKED(IDC_Btn_SetEsc, &CSettingDlg::OnBnClickedBtn_SetEsc)
	ON_WM_CLOSE()
END_MESSAGE_MAP()


LRESULT CSettingDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
//	switch(message)
//	{
//		case WM_COMMAND:
//
//			//I use the button to exit the dialog,which is static create by me!
//			if(wID==IDC_Btn_SetEsc) //static create the button
//			{
//				this->SendMessage(WM_CLOSE,NULL,NULL);
//				return TRUE;
//		
//				//break;
//			}
//
//		case WM_CLOSE:
//			// case WM_DESTROY://2008--4--24 xqh_xg
//			DeleteObjects(); //free the used object
//			break;
//
//	}//switch(message)

	return CDialog::WindowProc(message, wParam, lParam);
} 


void CSettingDlg::OnBnClickedBtn_SetEsc()
{
	PostMessage(WM_CLOSE);
}

void CSettingDlg::OnClose()
{
	DeleteObjects(); //free the used object

	CDialog::OnClose();
}
