Command line parameters can be handled in one of two ways:
1) You can access then in your Main function.
2) You can access them in your windows forms classes via the Application object.
If this is a console app, then use the first, otherwise use the second.
For console apps, find your Main function (it should be in the first file you created):
Sub Main(Byval args() As String)
Dim data As String = args(0)
Console.Writeline("Argument: {0}", data)
Console.Write("Press Enter to exit")
Console.Read()
End Sub
For winforms, all you need to do is access Application object:
For Each arg As String In My.Application.CommandLineArgs
Console.WriteLine(arg);
