How to get key presses on a windows form app?-CodePudding

I'm trying to make a picture move whenever I press "a". I'm using this function:

void Form1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if(e.KeyChar == 65)
            {
                peanut.Location = new System.Drawing.Point(0, 0);
            }
        }

Above the function it says 0 references if that helps. Also "peanut" is the name of the picture box.

When using peanut.Location = new System.Drawing.Point(0, 0); when the form loads, it works. I think the problem has to do with getting the key input, not how I'm moving the picture.

I tried using the KeyPress function, but for some reason it isn't working. This might be because e.KeyChar 65 isn't A, but if it isn't, could somebody show me a list of all the values and keys associated with them?

CodePudding user response：

Try setting the Form's KeyPreview to true in the Form's load event, like this:

private void Form1_Load(object sender, EventArgs e)
{
    this.KeyPreview = true;
}

Also if you want to move the picture box when the letter, a which has the value, 97 is pressed, try this:

void Form1_KeyPress(object sender, KeyPressEventArgs e)
    {
        if(e.KeyChar == 97)
        {
            peanut.Location = new System.Drawing.Point(0, 0);
        }
    }
