Detecting multiple keypresses in c# : <p>This is my program:</p>

<pre><code> private void Form1_KeyDown(object sender, KeyEventArgs e)
    {
        points++;
        textbox1.Text = points.ToString();
        textbox1.Refresh();
    }
</code></pre>

<p>I want the program to increase a variable everytime a key is pressed, it doesn't matter which one.</p>

<p>Right now my progam doesn't even start the event when i press a key, so i don't know what to do.</p>
