Question

I want to move a Diamond Shape in the form(for example 2 pixels every 200ms) horizantally.
I used the following code in From_Paint Event.

private void Form1_Paint(object sender, PaintEventArgs e)
{
    Graphics g = e.Graphics;
    Point p1 = new Point(5,0);
    Point p2 = new Point(10, 5);
    Point p3 = new Point(5, 10);
    Point p4 = new Point(0, 5);
    Point[] ps = { p1, p2, p3, p4, p1 };
    g.DrawLines(Pens.Black, ps);
}

I know how to move a picturebox but how to do with shape.

Thanks,
Ani

You’ll need to track your current location in a form level variable. If you do this, your Form1_Paint event can change the X pixel location each time it draws.

Just add a Timer to your form, and set it’s interval to 200ms. Each 200ms, add 2 to your current X pixel, and invalidate your control (so it redraws).

Edit: Add this to your form:

int xOffset = 0;

Then, in your timer_Tick:

private void timer1_Tick(object sender, EventArgs e)
{
    if (xOffset < 500)
        xOffset += 2;
    else
        timer1.Enabled = false; // This will make it only move 500 pixels before stopping.... Change as desired.

    this.Invalidate(); // Forces repaint
}

Change your paint event to:

private void Form1_Paint(object sender, PaintEventArgs e)
{
    Graphics g = e.Graphics;
    Point p1 = new Point(5 + xOffset,0);
    Point p2 = new Point(10 + xOffset, 5);
    Point p3 = new Point(5 + xOffset, 10);
    Point p4 = new Point(0 + xOffset, 5);
    Point[] ps = { p1, p2, p3, p4, p1 };
    g.DrawLines(Pens.Black, ps);
}
