Cannot resolve overloaded function

I'm getting the following error:

Code:

cannot resolve overloaded function `CtrlProc' based on conversion to type `long int'

My problem is that, as far as I know my function CtrlProc isn't overloaded to my understanding of it.

Code:

class MCCBase{
    public:
    EnableSubClass(BOOL cmd,BOOL create,BOOL size,BOOL move,BOOL draw,BOOL paint);
    LRESULT CALLBACK CtrlProc(HWND,UINT,WPARAM,LPARAM);
...

Code:

void MCCBase::EnableSubClass(BOOL cmd,BOOL create,BOOL size,BOOL move,BOOL draw,BOOL paint)
{
    if(cmd == TRUE)  SetWindowLong(ctrl,GWL_WNDPROC,CtrlProc);
}

I see no reason why it is happening.

Could you give the piece of code where you are getting the error?

You posted the correct definiton of EnableSubClass, but forgot to post the possibly incorrect definition of CtrlProc

Oops, I've edited the above to show the line where the error is occuring...

Also I haven't actually defined CtrlProc beyond the prototype, could that be the problem?

> Also I haven't actually defined CtrlProc beyond the prototype, could that be the problem?
Yes, that's a problem
Especially if you're already trying to call it from somewhere

Ok well I defined it and still I get the same error.

I'm tired, and my ability to read your mind is a little off at the moment.
Care to share what you actually wrote with the group?

lol, sorry.
It's probably easier if I post everything as it might be something else (although I don't see how) doing it..

Controls.h

Code:

#include <windows.h>

class MCCBase{
    public:
     MCCBase();
     ~MCCBase();
     void SetMetrics(int,int,int,int);
     void SetMetrics(LPRECT);
     void SetCaption(LPSTR);
     void GetMetrics(LPRECT);
     void SetParentWnd(HWND*);
     void EnableSubClass(BOOL,BOOL,BOOL,BOOL,BOOL,BOOL);
     void OnCreate(LPCREATESTRUCT);
     void OnSize(int,int);
     void OnMove(int,int);
     void OnPaint(HDC);
     void OnDraw(UINT,LPDRAWITEMSTRUCT);
     LRESULT CALLBACK CtrlProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam);
    private:
     int x,y,cx,cy,create,size,move,paint,draw;
     DWORD style,exStyle;
     char *className,label;
     HWND ctrl,parent;

};

Controls.cpp

Code:

#include "controls.h"

MCCBase::MCCBase()
{
  int x=0,y=0,cx=0,cy=0;
  DWORD style=0,exStyle=0;
  char *className="",*label="";
  HWND ctrl=NULL,parent=NULL;
}

MCCBase::~MCCBase()
{

}

LRESULT CALLBACK MCCBase::CtrlProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
    switch(message)
    {
    case WM_CREATE
    default:
     return DefWindowProc(hwnd,message,wParam,lParam);
    }
    return 0;
}

void MCCBase::EnableSubClass(BOOL cmd,BOOL create,BOOL size,BOOL move,BOOL draw,BOOL paint)
{
    if(cmd == TRUE)
      SetWindowLong(ctrl,GWL_WNDPROC,CtrlProc);
}

Just a guess....


SetWindowLong(ctrl,GWL_WNDPROC,MCCBase::CtrlProc);

Same error.

Code:

cannot resolve overloaded function `CtrlProc' based on conversion to type `long int'

I don't think this is going to be a very flexible so it doesn't matter now..
I'll find a better way.

Thanks anyway!
