Updating a view based on dialog input

My app has a check list box (in a dialog) in which the user indicates which list items he'd like to see in the main list view.  When the user presses the OK button, the code correctly updates the data structure indicating which items to display.  And the CListView::OnUpdate() method correctly accesses this display data, to figure out which items to actually display.  But I don't know how to force the View to re-draw itself when the user presses OK.  I can't call CListView::OnUpdate() directly, since MVC++'s Class Wizard makes OnUpdate() a protected method..  How do I get the view to re-draw?

In the handler of the command, in which you open the dialog call your document's UpdateAllViews(NULL) after the user has hit the Ok button.
For example:

void CMyApp::OnLstDlg()
{
  CListDlg dlg;
  dlg.SetDisplayedItems(m_pMyDocument->GetDisplayedItems());
  if(dlg.DoModal() == IDOK)
  {
    // The following will call the OnUpdate() of all
    // the views of the document which will get redrawn
    m_pMyDocument->SetModifiedFlag();
    m_pMyDocument->UpdateAllViews(NULL);
  }
}
