Code:

---

//==============================//
//Project: Send Keys            //
//==============================//

// Define
#define IsKeyDown(Key) GetAsyncKeyState(Key) & 0x8000 //Used to check if a key is down.


// Include headers
#include <windows.h>
#include <iostream>
#include <tchar.h>
#pragma comment(lib,"User32.lib")

///////std
using namespace std;

// Global Vars //
DWORD dwGameExe = NULL;
bool bFire = false;
bool on1 = true;
//thread - key send and ****.. for checks
DWORD WINAPI dwMainThread(LPVOID)
{
        //Check for the game
        for(;dwGameExe == NULL; Sleep(250)); // if exe is still null.. Sleep until game is found
        {
                dwGameExe = (DWORD)GetModuleHandle("TESV.exe");// Retrieves the module of "BFBC2Game.exe"
                //dwGameExe = (DWORD)GetModuleHandle("notepad.exe")
        }               
        // Do key checks etc.

//if (IsKeyDown(VK_LBUTTON))
if (IsKeyDown(VK_F2))
//if (IsKeyDown(MOUSEEVENTF_LEFTDOWN))
                on1 = !on1;

        if(on1 == true)
{
       
Sleep(100);


mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
Sleep(100);
mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
//Sleep(80);


Sleep(100);



mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
Sleep(100);
        mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
//Sleep(80);



//        mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
//        Sleep(10);
//        mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);

return 1;

}



        if(GetAsyncKeyState(VK_UP)&1) // F1 Hot keey to enable.. then let it see if it fires.
                bFire = !bFire;

        if(bFire == true)
        {
                mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
                Sleep(2500);
                mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);

MessageBox(NULL,"Project1.dll detached to Process!", "Successful Injection" ,NULL);

        }

        return 1;
}

BOOL WINAPI DllMain(HANDLE hModule, DWORD dwReason, LPVOID lpReserved)
{
    switch (dwReason)
    {
        case DLL_PROCESS_ATTACH:
            // Call thread
                        CreateThread(0,0,dwMainThread,0,0,0);
                        MessageBox(NULL,"Project1.dll detached to Process!", "Successful Injection" ,NULL);
            break;

        case DLL_PROCESS_DETACH:
            // Code to run when the DLL is freed
            break;
    }
    return TRUE;
}
