      GetActiveDocument() does that!

        Use: AfxGetApp()->m_pDocManager Here is an modified example that may help:

        void MyApp::InvalidateAllViews()
        {

        // Get position of first document template
        POSITION pos = m\_pDocManager->GetFirstDocTemplatePosition();
        while( pos )
        {
            // Get pointer to document template
            CDocTemplate\* pTemplate = m\_pDocManager->GetNextDocTemplate(pos);
            // Get position of first document using template
            POSITION pos2 = pTemplate->GetFirstDocPosition();
            while( pos2 )
            {
                // Get pointer to document
                CMyDoc\* pDoc = (CMysDoc\*)(pTemplate->GetNextDoc(pos2));
                if( pDoc )
                {
                    // Get position of first view
                    POSITION pos3 = pDoc->GetFirstViewPosition();
                    while( pos3 )
                    {
                        // Get pointer of next view
                        CMyView\* pView = (CVMyView\*)(pDoc->GetNextView(pos3));
                        pView->Invalidate();
                    }
                }
            }
        }
        

        }
