    I have a project that is due tomorrow @ 11:59P.M. I have a 4X4 board, broken down into four regions, each button is allowed to have a number from one to four. A button can not have a duplicate number in it's row column or region. This criteria must be met to generate a valid board. I was able to generate the random number for each of the sixteen buttons, but I am unable to find a way to check the buttons against each other. I tried to use IF THEN statements and a DO LOOP and it still does not work. If anyone can give me some directions or helpful tips it will be greatly appreciated.

    The reason why it's not working is because you haven't told your program what is a 'row' and what is a 'column'. Conditionals are there to confirm that a state is valid, which is not the same as an implementation of the state - so that's where your program falls apart.

    I'm not a VB guru in the slightest, so hopefully someone who is can give you an idea of the implementation for what I have described above.

    Good luck!

    Well thats because you need to design an algorithm, you could try a brute force or monte carlo type algorithm. A better approach would be to find constraints that limit the problem space.

    A gird can be implemented using a multidimensional array. You then prob want some functions like, check row and check column and check region. You'd probably be better off using a semi inteligent placing algorithm rather than placing the numbers randomly. As the grid fills up the problem space diminishes...

    For more on algorithms look at Robert Sedgewick his stuffs a bit more accessible than Donald Knuths.

    I'd agree with dmarsh - building the board while checking would seem a better way than placing the buttons randomly then trying to adjust them.

    If I understand the requirements correctly then the 'unique in block' requirement degenerates to checking the opposite corner of the block.
