How to associate an Extension with my program ?

[Guest]

Hi,
Is it possible to write a code in C++ to associate a given file extension
with our application? So that if user double click on the file on Windows
Explorer, our application will be launched.

Thanks

Yes. The shell's file associations are stored in the registry:

You certainly can manipulate the registry with code. Details are here:
