Hi,

I have to perform an action on all my MDI child views at times. The
amount of code copying is growing and growing - is it possible to write
some wrapper function that will perform an action on all views, by
passing a function pointer perhaps? This is what I have right now:

void CChildFrame::ApplyActionToAllViews_1()
{
    POSITION pos =
theApp.m_mDocTemplates["ImageViewports"]->GetFirstDocPosition();
    if (pos != NULL) {
        CMyDoc *pDoc = (CMyDoc
*)theApp.m_mDocTemplates["ImageViewports"]->GetNextDoc(pos);
        POSITION posView = pDoc->GetFirstViewPosition();
        while (posView != NULL) {
            CView *pView = pDoc->GetNextView(posView);

/******************************************************************
                finally in here perform the specific action using
pView.

*******************************************************************/
        }
    }
}

So I have to reproduce that whole block everytime I need to do a
different action on all my views. Anyway to make that more efficient?

Thanks
