示例1: PreTranslateMessage
BOOL CProgressDlg::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_KEYDOWN)
{
if (pMsg->wParam == VK_ESCAPE)
{
// pressing the ESC key should close the dialog. But since we disabled the escape
// key (so the user doesn't get the idea that he could simply undo an e.g. update)
// this won't work.
// So if the user presses the ESC key, change it to VK_RETURN so the dialog gets
// the impression that the OK button was pressed.
if ((!GetDlgItem(IDCANCEL)->IsWindowEnabled())
&&(GetDlgItem(IDOK)->IsWindowEnabled())&&(GetDlgItem(IDOK)->IsWindowVisible()))
{
// since we convert ESC to RETURN, make sure the OK button has the focus.
GetDlgItem(IDOK)->SetFocus();
pMsg->wParam = VK_RETURN;
}
}
