I keep getting a LNK2001 error (unresolved external
symbol "symbol") when calling AccessibleObjectFromWindow
() . I'm including the right libraries and it's
implemented correctly, what could be the problem?
Here's my code:

#include <windows.h>
//Active Accessibility Header Files
#include <winable.h>
#include <oleacc.h>

int FAR PASCAL WinMain(HINSTANCE hInstance, HINSTANCE
hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
{
   HRESULT hr;
   IAccessible * paccMainWindow = NULL;
   HWND hWndMainWindow = FindWindow(NULL,"Untitled -
Notepad");
   if(hWndMainWindow!=NULL)
   {
       SetForegroundWindow(hWndMainWindow);
       hr=AccessibleObjectFromWindow
(hWndMainWindow,OBJID_WINDOW, IID_IAccessible,(void**)
&paccMainWindow);  //error at this function call
   }
    return 0;
}

Please help,
