CoD4 NoRecoil help

[yge3d]

Yo guys... im new to game hacking, so i need help with a norecoil code....

#include <string>
#include <ctime>

using namespace std;

int main()
{
	HWND hWnd = FindWindow(0, "Call of Duty 4");
		if(hWnd == 0)
		{
			cout << "Could Not Find CoD4";
			system("CLS");
		}
			else
			{
				cout << "CoD4 Found!";
				cin.get();
				DWORD proccess_ID;
				GetWindowThreadProcessId(hWnd, &proccess_ID);
				HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, proccess_ID);
				if(!hProcess)
				{
					cout << "Could not open the process!";
				}
				else
				{
					BYTE newdata[] = {0x90};
					DWORD newdatasize = sizeof(newdata);
					if(WriteProcessMemory(hProcess, (LPVOID)0x00457C79, &newdata, newdatasize, NULL))
					{
						MessageBox(NULL, "Worked", "Success", MB_OK);
					}
					else
					{
						MessageBox(NULL, "Error cannot WriteProcessMemory!", "Error", MB_OK);
					}
					CloseHandle(hProcess);
				}
		}
		return 0;
}

Okay, so im pretty much sure D that the code works... but when i open the hack, IW3MP NOT RESPONDING... it worked perfect in ollydbg.. so whats the problem? can someone more experienced coder help me? I know that this way is 100% PB Detected... but just wanted to test it in bots.

-Thank you

Are you sure it's a 1 byte nop?
