Dynamically change an image in a Crystal Report at runtime

Question

I\'m using the Crystal Reports included with VisualStudio 2005. I would like to change the image that is displayed on the report at runtime ideally by building a path to the ima

I finally reached a solution using the byte[] tip posted here by Josh.

This solution applies if you are using a plain old C# Object to populate your Crystal Reports (see http://www.aspfree.com/c/a/C-Sharp/Crystal-Reports-for-Visual-Studio-2005-in-CSharp/ for info on this approach).

In your C# class, insert the following code:

private static byte[] m_Bitmap = null;

public byte[] Bitmap
{
   get
   {
      FileStream fs = new FileStream(bitmapPath, FileMode.Open);
      BinaryReader br = new BinaryReader(fs);
      int length = (int)br.BaseStream.Length;
      m_Bitmap = new byte[length];
      m_Bitmap = br.ReadBytes(length);
      br.Close();
      fs.Close();
      return m_Bitmap;
   }
}

Now, update your C# Object Mapping in CR using the "Verify Database" option. You should then see the Bitmap property as a CR field. Just drag it onto the form. It will be of type IBlobFieldObject. When you run, you should see your image.
