Agreed, that is the method I was using to find the message. The results are message box that shows the following text:
"The type initializer for 'GMap.NET.MapProviders.GMapProviders' threw an exception."
Looking further, it looks like I'll need to add my new source to GmapProviders. If I initialize to my map source (not in GmapProvders) I encounter an exception upon attempting to change map types.
Otherwise, is it possible to set a Control.MapProvider property to something other than an element in the GmapProviders enum?
Thank you for your time.
