Launching a Windows Forms App from a web browser with parameters

Question

I'm trying to launch an application with parameters, I can get the app to succesfully launch without parameters. But when I try to launch the app with a parameter I get no response. The current address I'm using to launch my Windows Form app from a URL is http://localhost/scheduler.exe?"10101" I've tried putting in a simple message box that displays the passed parameter but that doesnt work either.
