Question

I am working on a Windows Forms application in VS 2008, and I want to display one image over the top of another, with the top image being a gif or something with transparent parts.

Basically I have a big image and I want to put a little image on top if it, so that they kinda appear as one image to the user.

I’ve been trying to use a picturebox, but this doesn’t seem to have worked, any suggestions?

I was in a similar situation a couple of days ago. You can create a transparent control to host your image.

using System; using System.Windows.Forms; using System.Drawing;  public class TransparentControl : Control {     private readonly Timer refresher;     private Image _image;      public TransparentControl()     {         SetStyle(ControlStyles.SupportsTransparentBackColor, true);         BackColor = Color.Transparent;         refresher = new Timer();         refresher.Tick += TimerOnTick;         refresher.Interval = 50;         refresher.Enabled = true;         refresher.Start();     }      protected override CreateParams CreateParams     {         get         {             CreateParams cp = base.CreateParams;             cp.ExStyle |= 0x20;             return cp;         }     }      protected override void OnMove(EventArgs e)     {         RecreateHandle();     }       protected override void OnPaint(PaintEventArgs e)     {         if (_image != null)         {             e.Graphics.DrawImage(_image, (Width / 2) - (_image.Width / 2), (Height / 2) - (_image.Height / 2));         }     }      protected override void OnPaintBackground(PaintEventArgs e)     {        //Do not paint background     }      //Hack     public void Redraw()     {         RecreateHandle();     }      private void TimerOnTick(object source, EventArgs e)     {         RecreateHandle();         refresher.Stop();     }      public Image Image     {         get         {             return _image;         }         set         {             _image = value;             RecreateHandle();         }     } }
