Hi! I really like your sudoku solver.
In fact, i have been working on one myself. But i am facing some issues which i believe you go through. Your solving code has to be separate from the code under solve button. right? now how do you transfer the char / integer arrays of user input to a matrix. also how do you put the char / integer 2-d arrays (the solved sudoku) back into text boxes which accept only System:: String?
Would be nice if you could give some code snippets
