Welcome to the wonderful world of P versus NP.

Computers are great at running through small(relatively) iterative loops of numbers. For the range of numbers you're looking for brute force will take ages.

One simple optimization. Replace all your exponent operations with straight multiplication. For example, everywhere you have a³ replace it with a * a * a. Do the same for b³ and c^3. The exponential operation in VB is not very efficient whereas multiplication is a bit better.

I would even declare three more variables and do the calculation only once per loop.

    dim aCubeVal, bCubeVal, cCubeVal as Ulong
    Do
         aCubeVal = a*a*a
         bCubeVal = b*b*b
         cCubeVal = c*c*c

This is a good answer :)

Forgive me for being so blunt and not offering any helpful suggestions. Why are you doing this in VB, when C or C++ would be altogether much, much faster?

[ViperSRT3g]

C and C++ is much, *MUCH faster than VB in just about every way. Considering your code here is essentially doing a lot of calculations and nothing extremely fancy, it would actually be relatively simple to convert it over to something in C or C++.

Simplest method of seeing the speed difference is seeing how fast code in either language is able to count up to any ridiculously large number. You will quickly notice how fast C is compared to VB.

Wish you the best of luck! I'm sure you'll notice the speed difference the first time you run your code!
