Update only a part of a View with OnUpdateAllViews 2nd !

CrocodileBuck

Hi, i programmed a little app (SDI + RichCtrl). In this app. text is printed to the view when the program is started. When the user pushes the Button the ChangeText() fnct. in the doc will be called which only updates the rect with a new text. For a better understanding here is a pic: http://filehosting.at/images/download.php?file=585bdf52f01deea892f9e8b46fb652aa I tried with the UpdateAllViews() in the doc and OnUpdate() in the view.cpp. But it will not work ! To avoid posting too much code i coded a small sample which the same problem, perhaps you could have a look in the code ??? :-\ I really couldn't get it to work :(( :confused: http://www.filehosting.at/files/download.php?file=3e48616e695e66ed38f382a4c91fb3bc Many thanx for your help and best regards ;) Coc

This is the code from the doc:

CString CON_UPDATE_DEMODoc::ChangeText()
{
CRect MyRect(0,0, 100, 100);
CObject* pHint = (CObject*)&MyRect;

m\_cstrAusgabe  = " BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER \\r\\n\\ BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER";
m\_cstrAusgabe += " BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER \\r\\n\\ BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER";
m\_cstrAusgabe += " BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER \\r\\n\\ BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER";
m\_cstrAusgabe += " BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER \\r\\n\\ BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER";
m\_cstrAusgabe += " BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER \\r\\n\\ BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER BLUBBER";


UpdateAllViews(NULL, 1, pHint);
return m\_cstrAusgabe;

}

and this from the view:

void CON_UPDATE_DEMOView::OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint)
{
CMainFrame *pMF = DYNAMIC_DOWNCAST(CMainFrame, AfxGetMainWnd());
CON_UPDATE_DEMODoc *pDoc = DYNAMIC_DOWNCAST(CON_UPDATE_DEMODoc, pMF->GetActiveDocument()); //

m\_Rich.SetWindowText(pDoc->m\_cstrAusgabe);
if (pHint != 0)
{	
	InvalidateRect((CRect\*)pHint, TRUE);

	m\_Rich.SetWindowText(pDoc->m\_cstrAusgabe);
	return;

}
m\_Rich.SetModify(TRUE);	
CView::OnUpdate(pSender, lHint, pHint);

}

Since m_Rich is a CRichEditCtrl, why not just derive your view from CRichEditView? Or, you can derive it from CFormView and add a CRichEditCtrl to it. Otherwise, the way you rare going about this is all wrong.
