Arguments

I want to use the argument %1 (file directory) to open a file in my program. This argument is passed to the program when an associated file is opened. How do I access the information from the argument so that the file is opened? So far I have gotten my program to open when an associated file is opened.

Thanks in advance.

How is it being passed to your program - through a command line? Can you explain the process you're attempting in more detail

Yes, it is being passed through a command line.

You can retrieve the program command line (which includes the executable file name) as a string, or get an array of strings, where each element is an item on the command string:

Code:

' the command line passed to this program...
MessageBox.Show(Environment.CommandLine)

' the list of all the command line arguments 
' (first element is the executable name)...
Dim arg as String
For Each arg in Environment.GetCommandLineArgs
     MessageBox.Show(arg)
Next
