Trying to use OpenThread [modified]

[capricious_001]

Hey guys, I'm trying to use OpenThread however I get errors that its an undeclared identifier. I have included windows.h. I know OpenThread is defined in winbase.h however when looking within the header file I can see that the only close resembelence to this is OpenThreadToken which is not what I need. I am also using VC++ 6.0 btw. Does that mean I would have to update my header files? If thats the case would anyone know where the most recent version If I dont have to update my files, would anyone know a way to implement a function similar to OpenThread? Thanks, Robbie -- modified at 0:50 Monday 3rd July, 2006

Oh its a DLL Injector. It injects a DLL into an Open process. Here is a piece of the code for the DLL Injector. If there are some functions that appear unfamiliar like GetProcessThreads its because they are ones that creator defined.

bool DLLInject(DWORD pid, const char *path)
{
	//this will go through all TIDs of a process
	//and get one we can use
    DWORD tid[20];
	int inbytes = 20;
	GetProcessThreads(pid, &tid[0], &inbytes);

	if(pid == GetCurrentProcessId())
	{
        NumOut("Process will suspend itself and lock");
		return 0;
	}

	DWORD tiduse=0;
	for(int i=0; i 0x400000)
			{
				tiduse = tid[i];
				break; //one thread is good, break the loop
			}
			//NumOut("%d %X", tid[i], ctx.Eip);
		}
	}

	//do we have a good tid?
	if(!tiduse)
	{
		NumOut("No usable tid found");
		return 0;
	}

	//found a good tid already, now patch
	//excelent patching method

	HANDLE proc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pid);
	if(!proc)
		proc = OpenProcess(PROCESS_VM_READ | PROCESS_VM_WRITE, FALSE, pid);

	HANDLE thread = OpenThread(THREAD_ALL_ACCESS, FALSE, tiduse);

	bool ret = WriteMemPatch(proc, thread, path);
	CloseHandle(proc);
	CloseHandle(thread);
	return ret;
}

Im not sure its good for you but maybe it is some helpful to you i dont have vc6 ////header file typedef HANDLE (WINAPI *OPENTHREAD)(DWORD ,BOOL,DWORD); OPENTHREAD m_OpenThread ; HMODULE kernel32; kernel32=LoadLibrary(_T("kernel32.dll")); m_OpenThread =(OPENTHREAD)GetProcAddress(kernel32, "OpenThread"); HANDLE h=m_OpenThread(THREAD_ALL_ACCESS,false,GetCurrentThreadId());_**

2.2 I'm trying to call a Windows API, but the compiler gives an undeclared identifier error (C2065). Why?[^]
