SendMessage(error with integers)

[SteveCRM]

I keep getting pretty bad errors on this...like protection faults.

here is the code in my button:

int thenumber;
                char * pc;
                itoa(thenumber, pc, thenumber);
                
                srand(time(NULL));
                num1 = 1 + rand() % 3;
                num2 = 1 + rand() % 3;
                num3 = 1 + rand() % 3;
                
                SendMessage(ghWnd_Slot1, WM_SETTEXT, 0, (LPARAM) (LPCTSTR) itoa(num1, pc, 10));
                SendMessage(ghWnd_Slot2, WM_SETTEXT, 0, (LPARAM) (LPCTSTR) itoa(num2, pc, 10));
                SendMessage(ghWnd_Slot3, WM_SETTEXT, 0, (LPARAM) (LPCTSTR) itoa(num3, pc, 10));
