OK, basically I want to test if the shift key is pressed.
The method i've tried (unsuccessfully) is

private bool shiftPressed = false;
        private void CheckKeys(object sender, KeyPressEventArgs e)
        {
            //If enter is pressed and shift isn't
            //This allows for line breaks in a message by pressing shift & enter at the same time
            if (e.KeyChar == (char)13 && !shiftPressed)
            {
                //remove the line break caused by the enter key
                rtbInput.Text = rtbInput.Text.Substring(0, rtbInput.Text.Length - 1);
                Send();
            }

            //Else if shift is pressed
            else if (e.KeyChar == (char)15)
            {
                shiftPressed = true;
            }

            //Else if shift is depressed
            else if (e.KeyChar == (char)14)
            {
                shiftPressed = false;
            }
        }

This is run every time a key is pressed in the rich text box. Unfortunately, shift doesnt appear to trigger the KeyPressEventHandler

Can anybody show me an alternate method that i can use to test for the shift key?

Thanks,
Josh.

You need to use the KeyUp and KeyDown events. The shift key doesnt fire the KeyPress event.
The KeyUp and KeyDown events have an e.KeyData property which will hold a value you can check against the Keys enumeration:

if(e.KeyData== Keys.ShiftKey)

Edited 6 Years Ago by Geekitygeek: n/a

Thanks Ryshad!

Just a note to anyone else who sees this in the future, the KeyData of KeyDown for shift is equal to:
Keys.ShiftKey | Keys.Shift
whereas for KeyUp it's equal to:
Keys.ShiftKey

^^The above gave me a 10 minute debigging headache - Not really sure why MS has done this, but all the same - works now.
