Question

i have made a cool progressbar with text in the middle of it. Here is my code:

private void timer2_Tick(object sender, EventArgs e)
{
    progressBar1.Increment(+1);
    int percent = progressBar1.Value;
    progressBar1
        .CreateGraphics()
        .DrawString(
            percent.ToString() + "%", 
            new Font("Arial", (float)8.25, FontStyle.Regular), 
            Brushes.Black, 
            new PointF(progressBar1.Width / 2 - 10, 
            progressBar1.Height / 2 - 7)
        );
    if (progressBar1.Value >= 99)
    {
        timer2.Stop();
        this.Close();
    }
}

For some reason, the text shows up then disappears and other weird stuff. Why is that, and how do i fix it?

Try moving the drawing code into the Paint event, you are basically modifying the control’s visuals, so you need to handle this instead of the default painting behaviour.
