creating single-instance executables using python/py2exe

[Satchidanand Haridas]

Hi,

I have created an application using python/wxPython and py2exe. I have
associated a certain file extension with this application so that when I
double-click the file, my application is launched. The application runs
fine except that a new instance is created when I double click on two
different files. Is there a way in which I can make sure only one
instance is created? Any additional files are opened in the same running
instance? Would appreciate any comments/feedback.

thanks,
Satchit

You could open a listening socket to listen for "open file" commands.
If opening that socket fails (address already in use), connect a
client socket to it, send the appropriate "open file" command, and
exit.

That way, you even have a cross-platform solution.
