Ok i finished porting the VB code to c++ but ive hit a wall, it had 49 errors and i solved as many as i could but now im stuck

I hope someone out there can help :O

You have a bracket misalignment. The function

void GenerateKey(int iLower, int iUpper)
{

doesn't have a closing bracket. (or perhaps the for-loop inside that function).

If you're using Visual studio press:
ctrl-a , ctrl-k , ctrl-f to auto-format your code. That way you can see it yourself.

There are alot of additional errors, missing semi-colons, wrong return types etc.
I suggest taking a break, drink something and then tackle it one problem at a time :)

You have obviously gotten confused about the syntax of returning a value in VB, e.g.

Instead of doing

GetRandomNumberInRange = szS + Lower;

you should return the resulting value at that point. And change the GetRandomNumberInRange() 's signature too, so that it returns int.

oh ok thanks guys, ive had a good nights sleep so im going to tackle this again :(
