Hi
I am a newbie of Visual Basic.
And i am a student from Hong Kong.
My english is quite bad...so please don't use so difficult words
thanks...Orz

my problem:
i want to make a sudoku program with VB.
but i think just read the sudoku in the textbox is so easy...
i want to "GEN" a sudoku when the user press the button...

but when i work fews days ... i feel that is so hard for me
Hope someone can give me some hints of "GEN" sudoku. Crying or Very sad

Hi,

if you already wrote a program that solves Sudokus, it is not so hard to write one that generates them.

All you have to do is to fill random numbers into an empty grid, and check if the generated sudoku is uniq. If not, you enter more numbers.
If it is not solveable at all, you just start again with an empty grid.

I have a more detailed description as well as a few thoughts on speed here:

Hope that helped,
