Question

I have a bit of code which is meant to show a form for a period of time and play a sound.
However the Form stays open.

    static void Main(string[] args)
    {
        SoundPlayer sp = new SoundPlayer();
        ShowImage(@"Resources\Fish.png", "Fish", 256, 256, 1000);
        sp.SoundLocation = @"Resources\fish.wav";
        sp.Play();

    }


    public static void ShowImage(string img, string title, int width, int height, int timeout)
    {
        ImageContainer ic = new ImageContainer();
        ic.imgView.Image = Image.FromFile(img);
        ic.Text = title;
        ic.Size = ic.imgView.Image.Size;
        ic.Height = height;
        ic.Width = width;
        ic.ShowDialog();
        Thread.Sleep(timeout);
        ic.Hide();
        ic.Opacity = 0;
        ic.Dispose();
    }

It just stays with the form open doesn’t close or hide.
ImageContainer is a Form with a PictureBox called imgView in it.
I need it to time out for 1 second before it closes.

Answer 1

The line:

ic.ShowDialog();

Causes the form to show in a modal fashion, so that method blocks and prevents everything else from running until the form closes.

Change that line to:

ic.Show();

This is non-modal, and the rest of the method will complete.
