C++ :: Delegate Class - Support Void Class Function With No Parameters

I'm trying to write a simple Delegate class with a Bind() and Invoke() function. For now it only needs to support a void class function with no parameters. I've searched around and found quite a few exmaples, though, those class are heavily templated and I lose track trying to simplify it.

So far my code is following:

Code:
#include <windows.h>
class Test {
public:
void DoSomething() {
MessageBox(NULL, L"Test::DoSomething!", NULL, 0);

[Code] ....

The part I am having difficulty with is assigning &Test::DoSomething to the m_Callback variable.

&tObject::DoSomething works, yet _Callback which I pass &Test::DoSomething to does not work.

Also, why does the following line work:

Code:
m_Callback = &Wrapper<tObject, &tObject::DoSomething>;

When wrapper is like:

Code:
template<class tObject, void (tObject::*Func)()>
void Wrapper(void* Object)

Should it not be Wrapper<class-typename, parameter-1>(parameter-2) // This currently creates an error
