You want to use the Command function - here's what the docs have to say on it...
*******************************

Returns theargument portion of thecommand line used to launch Microsoft Visual Basic or an executable program developed with Visual Basic.
Syntax
Command
Remarks
When Visual Basic is launched from the command line, any portion of the command line that follows /cmd is passed to the program as the command-line argument. In the following example, cmdlineargs represents the argument information returned by the Command function.
VB /cmd cmdlineargs
For applications developed with Visual Basic and compiled to an .exe file, Command returns any arguments that appear after the name of the application on the command line. For example:
MyApp cmdlineargs
To find how command line arguments can be changed in the user interface of the application you're using, search Help for "command line arguments."
