Calling a pointer from a static member

In my class i have a pointer to point to different functions and i want to use that pointer to call the functions from a static member of the class.

I thought something like this would work...

Code:

---

(pPARENT.*m_pInputOnCharProc)(&wParam);

---

But it doesnt. I get these errors...

Code:

---

cdlgmain.cpp(192) : error C2597: illegal reference to data member 'CDlgMain::m_p InputOnCharProc' in a static member function
cdlgmain.cpp(192) : error C2568: '.*' : unable to resolve function overload

---

pPARENT is the variable thats holding the "this" of the class.

Any ideas?

You cant use any dynamic function or data in a static member. You could make the pPARENT variable static, and assign this to it every time you want to call the static function, but that seems a bit awkward. What are you trying to accomplish?

What do you mean by dynamic? If you mean any of the non-static functions and variables, then your wrong. I just need the pointer, which i have.

pParent is a pointer, so do:
(pPARENT->*m_pInputOnCharProc)(&wParam);

But the pointer is not static, so you cannot access it inside of a static function. Think of it this way. There is only one instance of each static member function and variable for ALL classes. Dynamic functions (non-static) can easily use these functions and variables, because they know where they are stored, etc. But think about it the other way. How does a static function know where a dynamic variable is stored? Which one should it use? If I have 15 instances of some class, which one's pPARENT should I look at? So, you cannot access non-static members from a static member. It is impossible, unless you pass in a this pointer to the function (in which case, it shouldnt be a static function).

I guess pPARENT is maybe a static member (bad idea) or a function parameter (also bad idea, like Zaei said, function should be normal method then).
Or it is a pointer casted to the base class...
Or this is a windows callback and pPARENT is casted from the lparam. (Actually the most probable, the name of the function pointer member indicates a WNDPROC)
