Hi Mark,

>Could you give me an idea how would a VFP window look like in order to process it from .Net?

The VFP form would just be a regular, but invisible form that has a unique caption. In .NET you would use something like this to find the window

		[System.Runtime.InteropServices.DllImport("user32.dll")]
		public static extern IntPtr FindWindow(string strClassName, string strWindowName);

		static void Main(string[] args)
		{
			Console.Write(FindWindow(null,"my unique id, for instance, a guid"));
			Console.ReadKey();
		}
