[Dev-C++] Subclass inside a class problem

[Brian B. <bcb...@ya...>]

Hi,
When trying to subclass an richedit control within a
class, I ran accross a problem. When I include a
subclass procedure in a class (the code shown below),
I get the error (Generated by Dev-C++): "aggregate
value used where an integer was expected", yet when I
include the subclass procedure outside the class, it
runs fine. How can I solve this?

class akorichedit{
private:
//...
WNDPROC wpOrigRichEditProc;
LRESULT CALLBACK RichEditSubclassProc(HWND hwnd, UINT
uMsg, WPARAM wParam, LPARAM lParam);
//...
public:
void create();
//...
};

void akorichedit::create(){
//... ERROR BELOW
wpOrigRichEditProc =(WNDPROC) SetWindowLong(
    (HWND)_hwnd,	// handle of window
    (int)GWL_WNDPROC,	// offset of value to set
  (LONG)RichEditSubclassProc
   );	// LINE 130
//... ERROR ABOVE
}

//...

LRESULT CALLBACK
akorichedit::RichEditSubclassProc(HWND hwnd, UINT
uMsg, WPARAM wParam, LPARAM lParam){
//...
}

Respectfully,
Brian
