Re: Handle / detect <Alt> key combinations

I have a custom panel component that derives from TCustomPanel. In its implementation, I have message handler for WM_KEYDOWN. The handler just posts the message to the application that hosts the panel in its form.

Two of the key combinations that I am interested in detecting are <Alt><Ctrl>F, and also <Ctrl>F. Here's the handler code;

procedure TAppPanel.WMKeyDown(var Message : TWMKeyDown);
begin
if (hwndApp <> 0) then
PostMessage(hwndApp, Message.Msg, Message.CharCode, Message.KeyData);
end;

The handler just posts the message to the application that handles it.

What happens is that when the <Alt><Ctrl>F combination is pressed, the application (whose handle is hwndApp) only receives <Ctrl>F combination, and processes it. Somehow the <Alt> key combination is never received by it. How can I make sure that it also receives <Alt><Ctrl>F combination as well?

GetKeyState, look it up in the win help.
using it to look at other interesting keys when an event takes place.
