Simple Memory Editing Tutorial in C++ Using WinAPI

I am trying to get this code to work out and test it, can someone tweak it a little bit to get it to work on something in WoW so that I can see visible results and
know it is working?

Code:

#include <iostream>
#include <windows.h>

#define WPMAddr  0x98765   
#define RPMAddr   0x12345 

using namespace std; 


int main()
{
DWORD pid;
const short WPMValue = 0;
short RPMValue = 0; 

HWND hwnd = FindWindowA(NULL, "World of Warcraft"); 
GetWindowThreadProcessId(hwnd, &pid);  
HANDLE phandle = OpenProcess(PROCESS_VM_OPERATION | PROCESS_VM_WRITE | PROCESS_VM_READ, 0, pid); 

WriteProcessMemory(phandle, (LPVOID)WPMAddr, &WPMValue, sizeof(WPMValue), 0); 
ReadProcessMemory(phandle, (LPCVOID)RPMAddr,  &RPMValue, sizeof(RPMValue), 0); 

return 0;
}
