灵异的OpenProcess

[BORLANDSUN]

最近在搞安全U盘的事情,今天写了一段DLL注入代码,在本机运行正常,拷到别的机子上时,OpenProcess返回目标进程的句柄,但后继调用不成功.后来发现,居然OpenProcess虽然操作成功,但GetLastError居然返回87(无效参数值).现在把代码贴出来,大家研究研究:

//	HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcessId);
	HANDLE hProcess = OpenProcess(PROCESS_CREATE_THREAD | PROCESS_VM_OPERATION | PROCESS_VM_WRITE, FALSE, dwProcessId);
	if(hProcess == NULL)
	{
		ShowMessage("失败");
	}
	else
	{
		ShowMessage("成功");
		ShowMessage(GetLastError());    	// 真灵异!!!!!
	}

	LPVOID pBuffer = VirtualAllocEx(hProcess, NULL, MAX_PATH, MEM_COMMIT, PAGE_READWRITE);
	BOOL Ret = WriteProcessMemory(hProcess, pBuffer, (LPVOID)lpszLibName, strlen(DLLPath)+1, NULL);
	PTHREAD_START_ROUTINE pfnThreadRtn = (PTHREAD_START_ROUTINE)GetProcAddress(GetModuleHandle("Kernel32"), "LoadLibraryA");
	HANDLE hThread = CreateRemoteThread(hProcess, NULL, 0, pfnThreadRtn, pBuffer, 8192, NULL);

	WaitForSingleObject(hThread, INFINITE);
	VirtualFreeEx(hProcess, pBuffer, 0, MEM_RELEASE);
	CloseHandle(hThread);
	CloseHandle(hProcess);

事实上,后面的几个API返回值都是表明操作成功的,但GetLastError()的值都是87.太怪异了.
我的成功的环境是Win7,失败的环境是XP和2003.我没有更多的电脑做测试了.
这几个电脑上装的都有360.难到那两台电脑上的OpenProcess都被HOOK了?

与OpenProcess无关

是的，是我的问题。我少拷了一个DLL所需的库。
