How do you use both Keys and Buttons in Visual Studio (C#)

Question

When I write a code that is supposed to move a picturebox in visual studio using keys (left & right) it looks like:

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
int j = pictureBox1.Location.X;
if (e.KeyCode == Keys.Right)
{
j += 5;
pictureBox1.Location = new Point(j, 130);
}
if (e.KeyCode == Keys.Left)
{
j -= 5;
pictureBox1.Location = new Point(j, 130);
}
}
and it works.
However, when I add button in my program this does not work anymore.
Why and how do you make a program that can use both keys and buttons?

Answer 1

You can use instead :

    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        int j = pictureBox1.Location.X;
        if (keyData == Keys.Right)
        {
            j += 5;
            pictureBox1.Location = new Point(j, 130);
        }
        if (keyData == Keys.Left)
        {
            j -= 5;
            pictureBox1.Location = new Point(j, 130);
        }
        return base.ProcessCmdKey(ref msg, keyData);
    }

You can use the tag : dotnet-csharp" for this question.
Please remove the tag "small-basic" ,That is another programming language.
