[HELP] Injectable DLL, without function calling.

I use this code the specifie the function when I want to call the DLL

Code:

---

void MainThread()
{
again:
    SystemProcessesScan();
    Sleep(350);
    goto again;
}

extern  "C"  __declspec(dllexport) void Main() {
        CreateThread(NULL,NULL,LPTHREAD_START_ROUTINE(Main  Thread),NULL,0,0);
}

BOOL h = false;
BOOL APIENTRY DllMain( HANDLE hModule,
                      DWORD  ul_reason_for_call,
                      LPVOID lpReserved
                                          )
{

        if(!h) {
                CreateThread(NULL,NULL,LPTHREAD_START_ROUTINE(Main  Thread),NULL,0,0);
                h = true;
        }
    return TRUE;
}

---

I would like to make it injectable and the MainThread is executed when the dll is injected with a simple injector. Without calling any function.


Thank you :)
