making a custom cursor in an MDI app

[fun-kelly]

Hi guys,

Okay, i have another question. in my MDI app i would like to have a custom cursor when the mouse is over a view window.

I have made the appropriate .cur file with the cursor's bitmap,
and have an IDC_CURSOR1.

I was hoping to tell Windows to switch cursors when it received
the ON_WM_SETCURSOR() message.

i tried first putting this in the view object, then in the child frame object.

both times, it gave me this kind of error:

ChildFrm.cpp(18) : error C2440: 'static_cast' : cannot convert from 'bool (__thiscall CChildFrame::* )(CWnd *,UINT,UINT)' to 'BOOL (__thiscall CWnd::* )(CWnd *,UINT,UINT)'

and pointed to ON_WM_SETCURSOR(). It seems that ON_WM_SETCURSOR should be in a CWnd object. But isn't CChildFrame derived from CWnd?

how can i use ON_WM_SETCURSOR() in my app? where should i catch this message so that i can switch to my custom cursor?

i am trying to follow the example of Prosise's MFC book p. 140:

ON_WM_SETCURSOR()
.
.
.

BOOL CMainWindow::OnSetCursor(CWnd *pWnd, UINT nHitTest, UINT message) {
     if (nHitTest == HTCLIENT) {
           ::SetCursor(my_cursor);
           return TRUE;
     }
    
     return CFrameWnd::OnSetCursor(pWnd, nHitTest, message);
}

thanx!
