Strings Not Working

Okay Im making a checkers (no parksie, not "draughts", CHECKERS) game, but I'm having some trouble. All I need to do is check the board, if there is an X, then put an X onto the end of another string. I've been using sprintf but its not working, the string always comes up empty :confused:

Heres The Bulk Of The Code Thats Not Working

PHP Code:

---

        for(i=1; i<=3; i++)  {
            for(a=1; a<=8; a++)  {
                if(a%2 == 0)  {
                    board[i][a] = 'X';
                }
                if(a%2 != 0)  {
                    board[i][a] = '_';
                }
            }
        }

        for(i=1; i<=8; i++)  {
            for(a=1; a<=8; a++) {
                if(board[i][a] == '_')  {
                    sprintf(FinalBoard, "_");
                }
                if(board[i][a]=='X')  {
                    sprintf(FinalBoard, "X");
                }
                sprintf(FinalBoard, "  ");
            }
        }

    SendMessage(GameBoard, WM_SETTEXT, 0, (LPARAM) (LPCSTR) FinalBoard);

board is the board with x and y coordinates. FinalBoard is the string I want to put the X in if there is an X....if not it puts an underscore.


If it helps. here's the cpp file

Never mind I got it. It worked using strcat :confused:
