Injecting another DLL with injected DLL

Hey guys, I need someone to help me fix this code
The "while(1)" freeze the application when I injected the dll , any idea??

Code:

void Inject()
{
	while(1)
	{
		if(GetAsyncKeyState(VK_DELETE))
		{
     LPTSTR  strDLLPath1 = new TCHAR[_MAX_PATH];// get dll directory
     ::GetModuleFileName((HINSTANCE)&__ImageBase, strDLLPath1, _MAX_PATH);
     strDLLPath1[strrchr(strDLLPath1, '\\') - strDLLPath1 + 1] = '\0';
     strcat(strDLLPath1,"Something.dll");
     
     HINSTANCE load = LoadLibrary(strDLLPath1);
		}
	}
}

BOOL WINAPI DllMain(HINSTANCE hinstModule, DWORD dwReason, LPVOID lpvReserved)
{  
     DisableThreadLibraryCalls(hinstModule);

     if(dwReason == DLL_PROCESS_ATTACH)
  {
	  
	  Inject();
	  
        return true;
  }
  
  return false;
}

Code:

void Inject()
{
  while(1)
  {
	if(GetAsyncKeyState(VK_DELETE))
          {
           LPTSTR  strDLLPath1 = new TCHAR[_MAX_PATH];// get dll directory
           ::GetModuleFileName((HINSTANCE)&__ImageBase, strDLLPath1, _MAX_PATH);
           strDLLPath1[strrchr(strDLLPath1, '\\') - strDLLPath1 + 1] = '\0';
           strcat(strDLLPath1,"Something.dll");
     
           HINSTANCE load = LoadLibrary(strDLLPath1);
           break; // exit the loop	
           }
   }
//will break to here;
}

Maybe you should add a Sleep in the loop?

}

What I mean is...
there's two DLLS
DLL A and DLL B
I want to inject DLL A in game , then after that when I hit the key, then only inject DLL B
But the problem is, when I inject DLL A , the game freeze .... wait until I hit the key, then only the game loads....
So is there any method not to let the game freeze when I inject DLL A and when in game I can use the trigger?

Code:

DWORD WINAPI Inject(LPVOID parblock)
{
	while(1)
	{
		if(GetAsyncKeyState(VK_DELETE))
		{
     LPTSTR  strDLLPath1 = new TCHAR[_MAX_PATH];// get dll directory
     ::GetModuleFileName((HINSTANCE)&__ImageBase, strDLLPath1, _MAX_PATH);
     strDLLPath1[strrchr(strDLLPath1, '\\') - strDLLPath1 + 1] = '\0';
     strcat(strDLLPath1,"Something.dll");
     
     HINSTANCE load = LoadLibrary(strDLLPath1);
                     if(load != NULL)
                          break;
		}
                Sleep(15); // The sleep is not needed, but I recommend it so you don't get 100% CPU usage
	}
        ExitThread(0); //safely end the thread
        return 0; //and really end it just in case
}

BOOL WINAPI DllMain(HINSTANCE hinstModule, DWORD dwReason, LPVOID lpvReserved)
{  
     DisableThreadLibraryCalls(hinstModule);

     if(dwReason == DLL_PROCESS_ATTACH)
  {
	  
	  CreateThread(NULL,4096,Inject,NULL,0,NULL);
	  
        return true;
  }
  
  return false;
}

I added a CreateThread function in the attach code. I also put a Sleep to prevent 100% CPU usage along with ExitThread + Check DLL.

I didn't test it, but I think it's

Happy hacking~ @justintics
