c++ injection does not work on windows 8.1

[mindjos]

Good morning ,

Here is the situation now, i did try using the Debugger inside the Visual Studio IDE and when i created my DLL and called it inside another program, it gave the following output.

'ViewCppDLL.exe': Loaded 'C:\Users\Emi\Documents\Visual Studio 2012\Projects\EmefoBankApp\ViewCppDLL\Debug\ViewCppDLL.exe', Symbols loaded.
'ViewCppDLL.exe': Loaded 'C:\Windows\SysWOW64\ntdll.dll', Cannot find or open the PDB file.

Welcome To C++ Dll
First-chance exception at 0x77e8e0b2 in ViewCppDLL.exe: 0xC0000142: DLL Initialization Failed.
Unhandled exception at 0x77e8e0b2 in ViewCppDLL.exe: 0xC0000142: DLL Initialization Failed.
The program '[5940] ViewCppDLL.exe: Native' has exited with code -1 (0xffffffff).

it loaded this sucessfully , the source code of the DLL

#include <stdio.h>
#include "hellodll.h"
#include <stdlib.h>
#include <windows.h>

extern "C" _declspec(dllexport)void sayHello()
{
	OutputDebugString("Welcome To C++ Dll\n");
}

BOOL DllMain(HINSTANCE hInstDLL, DWORD ul_reason_for_call, LPVOID lpReserved)
{
	switch (ul_reason_for_call)
	{
	case DLL_PROCESS_ATTACH:
		sayHello();
		break;
	case DLL_PROCESS_DETACH:
		break;
	case DLL_THREAD_ATTACH:
		sayHello();
		break;
	case DLL_THREAD_DETACH:
		break;
	default:
		break;
	}
}

As you can see , No worries. Now here is what, i injected the code into another Exe using the Injector source code i showed on here when i tried using Ollydbg to reverse the program to see if the code was injected i didnt see the string. i decided to use Debugview, to see if i can debug the application, i havent seen this 'Welcome to C++' inside the debugger.

Am i getting the process correctly or is there something i am missing, kindly let me know

No, you are not.
As you see there was

First-chance exception at 0x77e8e0b2 in ViewCppDLL.exe: 0xC0000142: DLL Initialization Failed.

I also get your point, but see what am trying to do.

I absolutely understood what you're trying to do, and that's why I recommended what I recommended. So far your dll is not prepared for being injected. Please read this twice. Until you get it realy ready for injection, there is no point to fumble with injection. I don't know how to make this simple thought be more clear. When you craft a spaceship, you test it on earth first, only then you launch it.

By the way, there is much more easy way to make sure your dll is successfully injected. The way is called Process Explorer. So you just get rid of all the odd stuff in dll, and inject it with your injector, and inspect your victim with Process Explorer.

Guess I still need to learn a lot then. Suppose I saw a video, maybe it would be more clearer.
Been battling with this all night haven't even slept peacefully lol

I see what I can come up with by tomorrow and get back to you, maybe other examples or tutorials you could render could be helpful

Thanking you again @igor most grateful

Afraid your DllMain does not return TRUE which makes Windows believe the loading has failed.
