GeoMedia C# code snippet to connect to a WMS server
Recently I was asked to look at some C# code to connect and display a feature from a Web Mapping Service (WMS) server. I wrote some driving GeoMedia code to test out the connection.

Please! Do you have an example using WFS with username and password?
I got an error in the 2nd Line that 'mapWindow" is doesnot exist in the current context. Can somebody tell me the solution ?
Thank You!
