Hi Mark,

>Will I need an infinite loop in .Net in order to constantly pull data from that window?

In .NET you create a simple form and then override the WndProc method:

protected override void WndProc(ref System.Windows.Forms.Message m)
{
  switch (m.Msg)
  {  
  case WM_COPYDATA:
    // do something
    break;
  }
base.WndProc(ref m);
}

This method is automatically called when the VFP application sends data. You don't need an infinite loop if you call Application.Run(form).
