Ithink you need to create an association between a file extension and your application. Therefore every time someone clicks on a file with your extension a new instance of your application is created.

In order to that to happen you need to modify some registry keys, to make the registry look like this:

 .myextension = MyApp
      MyApp = My Application
        |
         -- Shell
              |
               -- open
                    |
                     -- command = c:\directory\myapp.exe %1

Find this Microsoft Link to a VB sample code. Hopefully it is esay to change to C code.
