sendmessage

I can successfully send any single key message to an application, but don't know how to send combinations of keys (like Ctrl+F12, Shift+F1, Ctrl+R, etc..)

Tired doing this that way:

SendMessage(handle, WM_KEYDOWN, Keys.Control, 0);
SendMessage(handle, WM_KEYDOWN, Keys.F12, 0);
SendMessage(handle, WM_KEYUP, Keys.F12, 0);
SendMessage(handle, WM_KEYUP, Keys.Control, 0);

but this doen not seems to work.. (application act like only F12 is pressed, not Ctrl+F12)..

Any ideas how to make this work?
