Instead using CFormView::OnMouseActivate(...), I type the code like

"CWnd::OnMouseActivate(...)", then debug assertion failed message box does not poped up :)

 

but still I don't know correct reason of that...

 

emmm...anyway, thank you again.

 

In our sample we catch WM_MOUSEACTIVATE and don't call base maethod:

 

...

 ON_WM_MOUSEACTIVATE()
...

 

int CTabbedViewView::OnMouseActivate(CWnd* pDesktopWnd, UINT nHitTest, UINT message)
{
 return CWnd::OnMouseActivate(pDesktopWnd, nHitTest, message);
}

 

Hi~,

 

My dialog have CXTTabCtrl in it, and three formview attatched to that

CXTTabCtrl. (Formviews have several controls like checkbox, etc...)

 

I think it's very simple code...but it has problem with TabCtrl.

 

Active the dialog, it displayed with no problem, but when I click a formview

in tabctrl, "debug assertion failed" has occured...omg...

 

How can I get rid of that debug assertion failed message?

 

Ofcourse, in release mode, debug assertion failed message do

not poped up but still have problem with themes.

 

Debug break activate below line...

 

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

 

  //this line!!!!
  ASSERT(pParentFrame == pDesktopWnd || pDesktopWnd->IsChild(pParentFrame));

  // either re-activate the current view, or set this view to be active
  CView* pView = pParentFrame->GetActiveView();

  ....

  ...
}

 

 

void CFrameWnd::SetActiveView(CView* pViewNew, BOOL bNotify)
{
#ifdef _DEBUG
 if (pViewNew != NULL)
 {
  ASSERT(IsChild(pViewNew));
  ASSERT_KINDOF(CView, pViewNew);  <- this line!!!
 }

 

....

....

 

 

What problem do I have?

 

thank you.
