Well, the international (computer) language is English. So, if you want to make a global program, used by people all over the world, you will have much more users if you make your program (and the support for it) in English. Also if you post in English, you will get your problem solved much quicker because almost everybody here can understand english...
Though, I can understand that it is frustrating that you can't get help in your own mothertongue. Though, this forum consists of people from all over the world, and some do speak French, so they could help you (like Millenium_edition did) or help in translating.
In short, don't be afraid if you can speak English to post your question. Mostlikely there is always somebody who can help you or at least translate it for you
EDIT: and what Fraisie said also
