Re: Can't get MyView::OnUpdate to Trigger

Hi,
This is a continuation of a post from yesterday.
I have a serialized document. It stores data properly and
recreates the object ok when loading from a file.
Here is my CAstroCalc6Doc::OnOpenDocument fx which is called but
the CAstroCalc6View::OnUpdate() fx never gets called in the view
class. Or the OnPaint method for that matter.
--However I traced the code and a CView::OnUpdate object does get
called (the base class?) - but it bypasses my CAstroCalc6View class.
BOOL CAstroCalc6Doc::OnOpenDocument(LPCTSTR lpszPathName)
{
if(!CDocument::OnOpenDocument(lpszPathName))
return FALSE;
UpdateAllViews(NULL);
return TRUE;
}
How do I get it to call my CAStroCalc6View::OnUpdate Function??
-- Then I can reload my form data from the file...
I thought UpdateAllViews(NULL); was supposed to do it...
Tony:
It should be called. Are you sure it is not? Did you override OnUpdate() and put
a breakpoint in it? If you added it manually, check that it has the correct
signature:
virtual void OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint);
Note in particular that if your view has a different base class from CView, you
should *not* change the CView* in this declaration.
