This is my code:

C#

private void Form2_KeyDown(object sender, KeyEventArgs e)
{
  if (e.KeyCode == Keys.Up)
  {
    picturebox1.Location = new Point(100, 100);
  }
}

I'm getting no errors att all, and for some reason it's not doing anything, it's just not moving. Can anyone please help, what did I do wrong?

I think one problem is location. Imaging you hit this key twice. On the second click picturebox1 will be exactly at the same location as after the first hit, right? It's possible it was at the same location even after the click.

The second problem is the Form. If you have any focusable controls on the form, one of them will grab the focus (a Form cannot have the focus) and consume the keyboard events. To work around, you need "preview" the event on the form.

Another way is using Form.ProcessKeyCmd, you can override it.

Please see the property Form.KeyPreview. First thing, it can be true. For further detail, please hit F1 on this property and locate the Microsoft sample code — it will explain everything and show how to resolve your problem.
