Handling ALT Key on Controls
-
Hello, I want to create control(s) that would act like MS office 2007, so that when you press ALT key all controls that have hotkey will be repainted with hotkey drawn on itself. I dont want to use KeyDown, KeyPress, KeyUp events. Could it be all done trought some kind of extending of controls or so ? overriding WndProc or so ? Thanks.

You could override the control classes, or you could use CreateGraphics to draw your keys direct to the screen, then call Invalidate in the key up, so the form gets repainted.

Why on earth not ? You can use a WndProc to catch these events earlier, but you really have no option but to use them, you want to catch when a key is down, and when it's raised again.

Hello You can set a property called
KeyPreviewtotruein your form itself. Then handleKeyDownevent in the Form level. It will catch any KeyDown events in any control in that form before it is sent to that control.Regards:rose:

Try adding & in front of the letter that will be the hot key
