I have created a form with mmPictureBox.

Following an example at Akadia.com, I have created a databinding as such in the constructor method of an instance of mmMaintenanceForm:


InitializeComponent();

// this is essentially the code from Akadia.com, with only a minor
// change of my own dataset.
this.dsEmployeePhotos = this.oEmployeePhotosBiz.GetEmployeePhotos();
Binding bdPhoto = new Binding("Image", this.dsEmployeePhotos, "Photo");
bdPhoto.Format += new ConvertEventHandler(this.PictureFormat);
mmPictureBox1.DataBinding.Add(bdPhoto);
// the constructor method ends here
....
private void PictureFormat(object sender, ConvertEventArgs e)
{
// e.Value is the original value
Byte[] img = (Byte[])e.value;
MemoryStream ms = new MemoryStream();
// I have also tried int offset = 0
int offset = 78;
ms.Write(img, offset, imgLength - offset);
Bitmap bmp = new Bitmap(ms);
ms.Close();

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

The exception message I receive is "Cannot bind to property or column Photo on DataSource. Parameter name: dataMember". I have checked the that the column is included in my SELECT statement and have not misspelled it.

Any help is appreciated.

Thanks,
