Sudoku creation ActiveX

I need an ActiveX, to be used in a VB program, which will generate random Sudoku puzzles (and of course their solution). See Sudoku rules here: <[login to view URL]> And a generator/solver written in Java here: <[login to view URL]> The ActiveX will only create numerical matrices (will not output anything to the screen); it will accept difficulty as an input value (see above Java example) and return two text strings: *Puzzle* and *Solution.* Each one will be 81 characters long and represent the sequence of numbers starting from the left-topmost cell. *Puzzle* will be mostly filled with spaces (or any other character representing empty cells), while *Solution* will be filled with the complete solution. It must be fast enough to generate an average of 1 puzzle in 1 second (again, see Java example above) on a "medium" PC. ActiveX will be preferably written in VB 6 (please state which language you are going to use and why). Any working example will be more than welcome (and taken into account when choosing coder). ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
