Hi,
I have created a .net control and I have made it com visible and I am
consuming it from within Visual Objects code. But i get the following
error when calling the CreateDisplay() method:
COM object that has been seperated from it's underlying RCW cannot be
used.
It seems to happen when i try to change some viewable element of the
control. In this case I am trying to change the background colour.
Anyone have any ideas to try?

public class CurrentPhotoDisplay : Control,ICurrentPhotoDisplay
{
private PhotoDisplay CurrentPhoto;
public CurrentPhotoDisplay()
{
InitializeComponent();
}
private void InitializeComponent()
{

}
public void CreateDisplay(int ID)
{
MessageBox.Show(ID.ToString());
BackColor = Color.Black; ///ERROR HAPPENS HERE
}
