碰到个郁闷的事,主窗体重载WNDPROC想截获WM_KEYDOWN消息怎么截获不了?
procedure TFmain.WndProc(var Msg: TMessage);
begin
inherited;
if (Msg.Msg = WM_KEYDOWN) and (Msg.wParam = VK_ESCAPE) then
begin
ShowMessage( '截获了 ');
end;
end;

KEYDOWN事件截获不了?我尝试别的WINDOWS消息,都能正常截获,为什么这个就截获不了,帮忙~~~~~~~~~~~~~~~~~

[解决办法]
if Msg.Msg=CN_KEYDOWN then
begin
if Msg.CharCode=VK_RETURN then
ShowMessage( 'OK ');
end;
