Greetings to all:
I have a little problem. Earlier, in a web environment, I programmed an application in visual basic 6 that allowed Internet Explorer to execute an exe file, which check whether there was a 9.3 ArcMap session open, and can pass some parameters such as the layer to load, zoom, etc . Now with arcgis 10 this system is broken. The application generates an error "ClassFactory." How to develop the same thing with VB.NET? Any ideas? Thank you very much for your time.
