I want to run a Python shell from a DllMain() function.
This is what I came up with so far:

BOOL APIENTRY DllMain(HANDLE hModule,DWORD ul_reason_for_call,LPVOID
lpReserved)
{
	//----
	switch(ul_reason_for_call)
	{
	case DLL_PROCESS_ATTACH:
	{
	if (!Py_IsInitialized())
	{				
	BOOL res = AllocConsole();
				
	//I was going to use the handles but I heard its not the way to do
that
	//HANDLE OutHand = GetStdHandle(STD_OUTPUT_HANDLE);
	//HANDLE InHand = GetStdHandle(STD_INPUT_HANDLE);
	//HANDLE ErrHand = GetStdHandle(STD_ERROR_HANDLE);

	//Redirecting console
	freopen("CONOUT$","w",stdout);
	freopen("CONIN$","w",stdin);
	freopen("CONERR$","w",stderr);
	
	//Another way to redirect console
	//std::ofstream console_out("CONOUT$");
	//std::ifstream console_in("CONIN$");	
	//std::ofstream console_err("CONOUT$");

	//the printf prints on the new console after redirection
	printf("test");
	
	//opening stdout and stdin files to pass to python for redirection
	FILE* afile = fopen("CONOUT$", "w+");
	FILE* bfile = fopen("CONIN$", "w+");
				

	Py_Initialize();
	if (!Py_IsInitialized()) return(FALSE);

	//the bellow lines , instead of redirecting python crashes the dll
	PySys_SetObject("stdout", PyFile_FromFile(afile, "test","wb",
fclose)); 
	PySys_SetObject("stdin", PyFile_FromFile(bfile, "CONIN$","wb",
fclose));				
				
	//these lines produces no output
	PyRun_SimpleString("print 'hello'\n");
	PyRun_SimpleString("from IPython.Shell import IPShellEmbed\n");
	PyRun_SimpleString("ipshell = IPShellEmbed()\n");
	PyRun_SimpleString("ipshell()\n");
	}
	break;
	}
		
	case DLL_THREAD_ATTACH:
		break;
	case DLL_THREAD_DETACH:		 
		break;
	case DLL_PROCESS_DETACH:
		{
	FreeConsole();
	Py_Finalize();
	break;
		}
	}
	//----
	return(TRUE);
}

As you said all I was able to accomplish with AllocConsole was to redirect
the printf not the python

If it's not clear please don't hesitate to ask.
