Implant a callback inside a class

I'm not sure how to put a callback inside a class. What I have right now doesn't work.

Code:

---

class Listbox
{
        private:
                void Create();

                LRESULT CALLBACK WindowProcedure(HWND, UINT, WPARAM, LPARAM);
};




/////////////////////////////////////////////////////////////////////
///// Create /////
/////////////////////////////////////////////////////////////////////
void Listbox::Create()
{
    winc.hInstance = NULL;
        winc.hInstance = NULL;
    winc.lpszClassName = "Listbox";
        winc.lpfnWndProc = WindowProcedure;
    winc.style = CS_DBLCLKS;
    winc.cbSize = sizeof(WNDCLASSEX);

   
    winc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
    winc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
    winc.hCursor = LoadCursor(NULL, IDC_ARROW);
    winc.lpszMenuName = NULL;
    winc.cbClsExtra = 0;
    winc.cbWndExtra = 0;
    winc.hbrBackground = (HBRUSH)COLOR_BACKGROUND;
}

/////////////////////////////////////////////////////////////////////
///// Windows Proc Callback /////
/////////////////////////////////////////////////////////////////////
LRESULT CALLBACK Listbox::WindowProcedure(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch (message)
    {
                case WM_COMMAND:
                        break;

        case WM_DESTROY:
            break;

        default:
            return DefWindowProc(hwnd, message, wParam, lParam);
    }
   
    return 0;
}

The errors I get are:

error C3867: 'Listbox::WindowProcedure': function call missing argument list; use '&Listbox::WindowProcedure' to create a pointer to member
error C2440: '=' : cannot convert from 'LRESULT (__stdcall Listbox::* )(HWND,UINT,WPARAM,LPARAM)' to 'WNDPROC'


I am not too worried about the first error cause if I do what it says I get the second error and the first one disapears.

Without classes (like a ragular windows app) it works fine, but if it is in a class like this it gives those errors.

I sucseded in doing that. the LRESULT CALLBACK definitions should be the same, and maybe public?

This question has been asked, answered and discussed a lot in the past in the windows board, like here and here.

I'm sure a board search will turn up more information if the discussions in those threads I've linked to do not suffice.

ok I sucesfully implanted the windows thunk. But now I have a new question.

from msdn:

An application sends the LBN_DBLCLK notification message when the user double-clicks a string in a list box. The parent window of the list box receives this notification message through the WM_COMMAND message.

---

The question is, is the LBN_DBLCLK (and alike notifications) always sent to the parent. My thunk doesn't seem to catch any WM_COMMAND.
