problem with keypress function

[MehmetKocc]

Hi What i need to do is to get keyboard letters and "letter combinations" which is the core of my problem for ex: when i press alt + f4 i wnat to see alt f4 in the label i have the code snippet

protected override void OnKeyDown(KeyEventArgs keyEvent)
{

        label1.Text = "";
        
        label1.Text=keyEvent.KeyCode.ToString();

        //while(?)         i wanted to write a while loop for while the key is still pressed(down)
        //label1.Text=keyEvent.KeyCode.ToString()+"+"+label1.Text;
        
    }

Can anyone show me a way to do it please? Thanks...

hmmmm seems suspicious... but I think KeyEventArgs has something to detect if buttons like alt, shift, ctrl are currently pressed.

Life goes very fast. Tomorrow, today is already yesterday.

forget the loop, loops seldom belong in an event handler. Create one method that is used for both KeyDown and KeyUp events. :)

Check the value of keyEvent.Alt, it will be true if the alt key is held down.

Hi, You can override the ProcessCmdKey() function in Control class like this : protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { if (keyData == (Keys.Alt | Keys.F4)) { //Your Code } return base.ProcessCmdKey(ref msg, keyData); } Hope this helps, ramz_g :-)
