Solution 1

Why on earth are you checking (e.KeyCode + 1)?

To do this, you have to keep track of the last key pressed. Then, in the KeyDown event, you check to see if the last key pressed is a space and the current key pressed is a space. If they are both true, then you set the e.Handled and e.SuppressKeyPress properties to true.

Now, if the current key pressed is not a space, put that key in the tracking variable.
