[python-win32] Passing arguments/values back and forth between separate executables at/during runtime

[Jacob Kruger]

Cool - will check it out.

Could you possibly test the following for me though, in meantime, just to make sure the separate/external app will in fact do what I want/need it to?

If you hit enter on tryMe.exe, it should just play back the MP3 file included in that zip file, but anyway.

Thanks

    Alternatively, what would maybe be a better method for passing string/numeric values back and forth between two separate executables in this style/sense?

    Something like peek/poke back in ooooold days, or something like writing values to windows registry?  Don't think that it should really be necessary, and think something as simple as either just passing values back and forth in temporary text files, or sqlite database files, or even just pickled python objects could do the trick, but, what do you guys think?

  The Google search term you want is "interprocess communication."  There are a number of ways to do this, although many of them tend to be system-dependent.

  Windows has the concept of a memory-mapped files -- essentially a chunk of memory pages that can be shared between multiple processes.  That's awfully easy, but I don't know if there is a Python mapping.  You'd be responsible for wrapping a communication scheme around that.

  Windows and Linux both have the concept of named pipes, which are very much like network sockets that don't happen to travel across a network.

  Heck, even a traditional TCP socket would work for your purpose.  They are very easy to handle in Python, and it would even let you split your work across several computers.
