Compiler error C2440, and pretty strange and uncomprehensible text in it !

[Amn]

Now that i have caought your attention, i will show you that as a matter of fact there is something strange MSVC++ 7.0 tells me, but first the code:

I have a class that dispatches threads, in such a fashion, that it is possible for a thread to run a foreign object's member function. For example you have a thread object "thread obj1" and an object "datafeed obj2". "thread" class has a constructor which runs any member function (void parameters) of any other class, here "datafeed" asynchroniously (in context of parallel thread). Practically i am having problems here:

class thread
{

	template<class T, DWORD (T::*pMember)()> friend DWORD WINAPI callFunctor(LPVOID pObj)
	{
		return (((T*)pObj)->*pMember)();
	}		

	HANDLE	hThread;
	DWORD	threadID;
		
public:

	class createThreadFailed {};

	template<class T> thread(T* pObj, DWORD (T::*pMember)())
	{
		DWORD (WINAPI *pThreadProc)(LPVOID pParam) = callFunctor<T, pMember>;

		hThread = CreateThread(NULL, 0, pThreadProc, pObj, 0, &threadID);

		if(!hThread) throw createThreadFailed();
	}

};

THe code is extracted from a valid C++ header, but in order for it to be readable i changed it a bit, thrown out unneded functions etc. So please take it with a grain of salt, however, the precise structure of the idea is present in it.

Basically thread object constructor receives parameters of an object, and a member, which together form a callable entity (member) which the new thread will run.

The problem is, that i get this compiler error:
"error C2440: 'initializing' : cannot convert from 'DWORD (__stdcall *)(LPVOID)' to 'DWORD (__stdcall *)(LPVOID)'
None of the functions with this name in scope match the target type
example.cpp(27) : see reference to function template instantiation 'thread::thread(T *,DWORD (__thiscall dataFeed::* )(void))' being compiled
with
[
T=dataFeed
]"

Isn't it funny how compiler cant convert from the same type to the same type ?

I am not one who gives up easily, so I actually had tried some options. For instance, since templates are instantiated at compile time, a constant template parameter is required, and hence passing a function parameter further as a template parameter wouldn't work. So i actually tried to use member pointer as a 'const' in the constructor, but then other kind of errors show up. I also tried to make member address a template parameter instead of constructor parameter, but then MSVC++ doesn't welcome template constructors in non-template classes. The last option that i DONT WANT TO TRY is substiting thread parameter with a functor instead of a sole object pointer, and thus avoiding to pass member function address all together. This is all i got on my hands. Could you help me with the first two options ? I dont want to choose other solution, because if it is possible to get either of the two to work, they seem a very elegant way.

Thanks in advance !
