Well, that is fine for the source code I write myself. I did write a class to avoid using the faulty one. But, Stingray (Roguewave) uses the bad class in their customize toolbar dialog. I could mess with their source code, but I'd like to avoid doing so.
Thank you for the info !

That explains it All
I was just wondering what Stingray was about to do to your code\n

Hi,
i want to update only a part of a view with UpdateAllViews().
I read that the simpliest way is to call UpdateAllViews() from the doc and pass a CRect to the view's OnUpdate().
The rect which is passed to the view's OnUpdate() ist the part which is updated.
But it wont work  , I tried it for some hours now, could you helpme? 
Perhaps you know a tut which covers this problem i only found the simple UpdateAllViews(NULL)samples ?
Here is some source from me which updates the whole view doc.cpp:
CString CMyDoc::LoadFile(CString cstrSearchString, CString *ptrArrFileNames, CString cstrFileExtension, int iZaehler)
{
m_iZaehler = iZaehler;
ptrMlf->loadmyfile (cstrSearchString + m_ptrArrFileNames[iZaehler],cstrFileExtension);
m_cstrText = ptrMlf->lf_cstrText;
UpdateAllViews(NULL);
return m_cstrAusgabe;
}
Here the code from the view.cpp:
void CMyView::OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint)
{
CTheReaderDoc *pDoc = GetDocument ();
CRichEditCtrl &rCtrl = GetRichEditCtrl();
rCtrl.SetWindowText (pDoc->m_cstrAusgabe);
rCtrl.SetFont(pDoc->m_ptrFont);
rCtrl.SetModify(TRUE);
}
Many thanx & best regards

UpdateAllViews() gives you TWO parameters that get passed to all the
CView::OnUpdate() calls.
What about passing a pointer to a CRect in one of those paramters?

The code you posted is not trying to use a CRect so how are we supposed to know what you are trying that is not working?

Thx for yor quick replies,
here the code which tries to pass a pointer to CRect:
Doc.cpp:
CString CMyDoc::LoadFile(CString cstrSearchString, CString *ptrArrFileNames, CString cstrFileExtension, int iZaehler)
{
m_iZaehler = iZaehler;
ptrMlf->loadmyfile (cstrSearchString + m_ptrArrFileNames[iZaehler],cstrFileExtension);
m_cstrAusgabe = ptrMlf->lf_cstrAusgabe;
CRect *MyRect;
MyRect(100, 100, 100, 100);
CObject* pHint = NULL;
pHint = reinterpret_cast<cobject*>(MyRect);
UpdateAllViews(NULL, 1, pHint);
return m_cstrAusgabe;
}
Many many thanx and best regards

That code compiles?
Maybe try something simpler:
CRect MyRect(100, 100, 100, 100);
CObject* pHint = (CObject*)&MyRect;
UpdateAllViews(NULL, 1, pHint);

Thanx,
it will work, i could now pass the CRect!
Simple is Simply the best way
But do you know what i have to do in the OnUpdate of the viw.cpp ?
The view will not automatically update only the rect area ?
I men when i print text in my view and then load new text my version of UpdateAllViews should only update the rect ???
But how?
Sorry for my stupid question  but i m really confused !
Many thanx
Croc

A simple call to InvalidateRect() in your OnUpdate() overrides should do it.
void CMyView::OnUpdate(CView* pSender, LPARAM , CObject* pHint)
{
InvalidateRect((CRect*)pHint, TRUE);
}

Hi Mr. Salsbery,
i tried
InvalidateRect((LPCRECT)pHint, TRUE);
but it won't work 
Thanx for all your help

What does "won't work" mean?
If you're using a rect of (100,100,100,100) then nothing will
happen, since the rect has no dimensions (width and height are 0).
Try a valid rect!

Hi,
yes thats right but i tried it with
CRect MyRect(0,0, 200, 150);
CObject* pHint = (CObject*)&MyRect;
and this fails too!
Manx thanx and best regards

What does "fails" mean?
Doesn't compile? Crashes at runtime? Nothing happens?
It marks the area for updating. The next WM_PAINT message will
update that area. If the same exact data is drawn as on the last WM_PAINT,
you're not going to see a difference.

You need to change something between calls to UpdateAllViews() if
you want to see something different in the view. What are your views
drawing? Something from the document? If so, change the document.

Only you know what's going on in your views.
The text data must be coming from somewhere...
Change it and update the views!
And make sure changing it doesn't already cause an update implicitly,
or you still won't see anything.
If the view is a window not in your control (where you don't do the painting,
like an edit control), then you may not have control over updating regions of
the window.
If you are doing the painting in your view, look at the invalid rect in the WM_PAINT
handler - you should see that your update rect is there. What you do with that info in
your painting code is up to you.

You are in deep deep sh*t at this point dude. Maybe you should just treat the buck to a Filet-O-Fish and call it a day. 
I'm outta here, have a great weekend! ![Beer | [beer]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/beer.gif)

And you're using SetWindowText()? I've not ever tried that, but it just seems odd.
