I have an application that allows only one instance of itself to run. I'd like to pass in the command line args from a second instance that's trying to start up, then dismiss the second instance before it comes up. Is there any easy way to do this?

hi

there is no direct way to send cmd parameter, b'cas u r not controling the application. The easiest way to pass parameter is  using file, whenever u start your appliction write some signeture in the file ( temp file ). & delete on exit. Using this file on start of your application always check the signeture. if signeture exits return false. This is what i did in my project.

OK, this is interesting. Is the idea that you write the command line params to the temp file? Then send the first instance of the app, say, WM_ACTIVATEAPP - when the first instance receives the message, it could then check the temp file for params and handle accordingly. Seems this could be done with the registry as well.
