I am using forms databinding to show an image in the database in a
pictureBox.  To do this I am handling the Format event to convert the byte
[] to a bitmap:

Binding bind = new System.Windows.Forms.Binding("Image", this.dataSet1,
"Employee.Image");
bind.Format += new ConvertEventHandler(Image_Format);

private void Image_Format(object sender, ConvertEventArgs e)
{
    if (e.Value is System.DBNull)
    {

              ///   How do we handle the DBNull???
        return;
    }

    // e.Value is the original value
    Byte[] img = (Byte[]) e.Value;

    MemoryStream ms = new MemoryStream();
    ms.Write(img, 0, img.Length);
       Bitmap bmp = new Bitmap(ms);
    ms.Close();

       // Writes the new value back
    e.Value = bmp;
}

My problem occurs when the value in the database is NULL.    if I don't do
anything then I get an Invalid cast from System.DBNull to
System.Drawing.Image.   I also tried :

e.Value = (Bitmap) null;

but i get a memory exception

Thanks
