Question

I have this textbox I use to capture keyboard shortcuts for a preferences config. I use a low-level keyboard hook to capture keys and also prevent them from taking action, e.g. the Windows key, but the Alt key still comes through and makes my textbox lose focus.

How can I block the Alt key, so the focus is kept unaltered at my textbox?

Answer 1

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Alt)
    {
        e.Handled = true;
    }
}
