Hello~~

I stick CExtPPVW CExtGridWnd on Dialog.

When I do Dialog-Create by a program, I seem to have to appoint GetDesktopWindow in pParentWnd.

Unless I go through such a procedure.
"Assert" appears by a print preview.

Why?

We failed to reproduce this problem with the ProfUIS_Controls sample. Could you provide us with a small test project demonstrating the problem?

We are recoding the printing and print preview at the moment. We will notify you later about this.

Hi

I cannot make a reproduction program.
Assert appears first of all at the following points.

-----------------------------------------------
int CView::OnMouseActivate(CWnd* pDesktopWnd, UINT nHitTest, UINT message)
{
int nResult = CWnd::OnMouseActivate(pDesktopWnd, nHitTest, message);
if (nResult == MA_NOACTIVATE || nResult == MA_NOACTIVATEANDEAT)
return nResult; // frame does not want to activate

CFrameWnd* pParentFrame = GetParentFrame();
if (pParentFrame != NULL)
{
// eat it if this will cause activation
>>>>>>>>ASSERT(pParentFrame == pDesktopWnd || pDesktopWnd->IsChild(pParentFrame));
-----------------------------------------------

Please answer it if I seem to understand a cause.
It moves commonly if I do normal how to make.

Thank You

Please contact us via email at support@prof-uis.com. We have a solution that should fix this problem.

Hi

When I am for "Debug", this Assert occurs.
Please move to a print preview screen.
With a mouse, please click a preview screen
Assert occurs. (-o-;)

[ A cause of an error ]
In SDI Frame, I make a dialog.
It seems to be not good when I set up a preview in the dialog.

We are sorry for the delay with this reply. Thank you for reporting the problem. You can fix it by updating the source code of the CExtPPVW_HostWnd::OnMouseActivate() method:

int CExtPPVW_HostWnd::OnMouseActivate(CWnd* pDesktopWnd, UINT nHitTest, UINT message)
{
      ASSERT_VALID( this );
int nResult = CWnd::OnMouseActivate( pDesktopWnd, nHitTest, message );
      if( nResult == MA_NOACTIVATE || nResult == MA_NOACTIVATEANDEAT )
            return nResult;
CFrameWnd * pParentFrame = NULL;
CWnd * pParentWnd = GetParent();
      for( ; pParentWnd != NULL; pParentWnd = pParentWnd->GetParent() )
      {
            if( pParentWnd->IsFrameWnd() )
            {
                  pParentFrame = STATIC_DOWNCAST( CFrameWnd, pParentWnd );
                  break;
            }
            if( ( pParentWnd->GetStyle() & WS_CHILD ) == 0 )
                  break;
      }
      if( pParentFrame != NULL )
      {
            CView * pView = pParentFrame->GetActiveView();
            HWND hWndFocus = ::GetFocus();
            if(         pView == this
                  &&    m_hWnd != hWndFocus
                  &&    ( ! ::IsChild( m_hWnd, hWndFocus ) )
                  )
                  OnActivateView( TRUE, this, this );
            else
                  pParentFrame->SetActiveView( this );
      }
      return nResult;
}

Hi

Were you able to reproduce the Assert situation?

Thank
