VB.Net application listen to command line variable

I have a need to pass a variable from a commandline parameter to a vb.net form in VB.  I have no clue on how to set the vb.net form so that it is actively listening so that when the variable is pass, it would capture what value is pass to the form.

Anyone have any examples or can point me to a website?  Tried googling, but can't seem to find anything.  

An example, would be creating a bat file that pass any value (a parameter) and the form can pop up with a messagebox, indicating what was pass to the form.  The vb.net form will need to be actively open and listening.  When the bat file is run, it will ask for a value, user enter the value and then that value is pass to the form.  Form will pop up with a messagebox indicating what value is pass.

I don't think you can do this exactly as you've outlined.  Your argument needs to be passed when the executable is launched.
However, there may be other ways of accomplishing this.  One method would be to use the filesystemwatcher; when the batch file is run, it passes that variable onto a predescribed filename/extension.  When the trigger for the file creation hits, it could popup the data contained within that file.

See an example here: http://www.techrepublic.com/article/use-the-net-filesystemwatcher-object-to-monitor-directory-changes-in-c/

You can make a single instance application and then handle the StartupNextInstance event to accept the new argument passed in

Thanks for the information.  Looking at the example, might be something that I can use.  Due to year end, I am tied up, but will focus once I'm back.
