I added an event on the Windows right click menu for the .DOC extension. I have this function calling a VB.NET program and passing the filename/path of the selected file. If multiple files are selected, it calls the application as many times as you have files selected but I want one instance of the application to receive all of the filenames.
So I was thinking if the application would detect if another one is running, send that application the filename and close itself. Maybe someone has a better idea how to handle this as well?
