getting an argument from Main

Does any one know of a way I can send arguments to a VB app. Example: By double clicking on a .doc it will open MsWord with the doc file loaded. I have made the association in Windows but I don't know how to get the argument or file name from system. I have tried the getcommandstring() api and I guess I could make that work but it would take alot of programming.

Command$ returns the command line in VB

ShellExecuteEx is what opens associated files. I'm assuming you have associated a file type with your VB app. When you double-click on the file, and your VB app opens, right?

On double-click the shell places the filename as the first commandline parm in a call to your code.
