I am working on creating a small app that will allow a user to right click on one (or more) files in a directory and click on "Create PDF's" or "Combine All Into 1 PDF".

I am using PDF Creators COM interface and I have all of that programming done. What I need to do is be able to read in multiple file names. So whether the user right clicks on one file or multiples, I will be able to read all of the file names into variables and then perform the requested action.

So I guess I just need help reading command line arguments and determining how many were passed.

Thanks,

Ryan

If you're staring up a form directly, you need to use a module instead.  Create a new module with a public sub named "Main" like this:
Module MainModule
    Public Sub Main(ByVal CmdArgs() As String)
        '...
    End Sub
End Module

Then to use that sub go to the project's properties page, make sure "Enable Application Framework" is NOT checked, and you should be able to choos "Sub Main" as a start up object.  Now if you need to show a form you can do so from the sub, and the command line arguments are available in the CmdArgs parameter for the sub.

Okay I got that part, but I don't know how to break out the different file names.

So if someone right clicks on like 4 files, and then selects my application in the context menu, those 4 file names will be sent as command line arguments to my application. So I need to know how to seperate those file names out, probably using an array.

Just can't find the right code.

CmdArgs is already an array, and should hold one file name at each index.

Okay so I just need to check the length of CmdArgs and then loop through it to get all the file names that were passed to it?
