Everyone knows Excel, it is a very useful and smart software. It can help us to do lot of things, especially in financial affairs, personal budget, etc. It is very very easy to use it!

But to use it on an advanced application developpement, is really difficult! Maybe that’s because my level is not high enough, maybe I’m not clever enough, maybe many reasons. Anyway, I spent too much time on it that I have no more time for my site, for this blog!

Luckly, today I’ve just finished it in this afternoon! So I come back !

Hope I will have a good note!
