I have two questions, the first of which is simple but I can't think of what the answer is:

<code deleted and saved as attachment>

lol sorry...

I get the following complier error:

<errors deleted and saved as attachment>

why is 'string' undeclared? Where do I declare it? It is just that I have never designed a "Windows Form Application" (GUI) app before I know with the command based one you just include the declaration at the top followed by "using namespace std;" but I am unsure of where the declaration goes in this circumstance.
***
Secondly, in my declaration of the "mainarray"... there must be an easier way to do this... I know you can do a loop like so:

int arr[3][3];
for (int x=0; x<3; x++)
   for (int y=0; y<3; y++)
      arr[x][y] = 0;

but you can't use a loop with the textboxes as you can't say:

arr[x][y] = textboxxy;

so there must be an easier way of doing this?
***
Apologies for the long post... I am aware it probably isn't necessary to include all the code that I did.

Thanks in advance,

Dan

One problem is that you included <string> but failed to specify std namespace. line 975: std::string blabla

I'm aware of that,

the declaration at the top followed by "using namespace std;" but I am unsure of where the declaration goes in this circumstance.

If I add it in above line 974 I get the following error:
