The user would give out the number of buttons.

void CreateButtons(int num)

    Button[] button = new Button[num];
    for (int i = 0; i < num; i++)

        // Anything that cocoonwls said.

Every button should have its own working onclick code

    Button b = sender as Button;
    switch (b.Name)

if(e.KeyChar==37)<br />
                txtStatus.Text = "You've pressed the left arrow key.";<br />
