News/release from Cheff:

Hello, voila after a surprisingly small piece of time is spent on the project, here is the 1st version montrable ().
Basically the program displays a blank grid, you can add numbers by touching the box manner.
The OK button solves the grid you entered, the X button is used to erase everything.
For the moment, what he faudrai change it is the "graphics", and yet it is a great word.
Otherwise, the resolution algorithm used is a method of backtracking, which explains a little slow applicability in a grid resolve difficult [for a 5sec Until I found].

The Roma, as well as the sources are in the attached file.

In any case a big thank you to members of the forum who help me
