Whenever you click on a window, it will get focus automatically.

I really cant understand your requirement. In this case, you will never get focus on dialog in your question.

Dear, Dear,
I understand the problem now.
Refer your original code,
You are comparing window with focus with parent window of view, which will be child frame.
You need to modify your original code to this,

int CImageView::OnMouseActivate(CWnd* pDesktopWnd, UINT nHitTest, UINT message)
{
if((*GetFocus())!= (*this))
SetFocus()->RedrawWindow();
return CWnd::OnMouseActivate(pDesktopWnd, nHitTest, message);
}

hi I have written this

int status = CView::OnMouseActivate(pDesktopWnd, nHitTest, message);
if(GetFocus()!=GetParent())
GetParentFrame()->SetFocus()->RedrawWindow();
return status;

what i want is it will not redraw window when foucs is on the same window and i clicked.

but in this code it always go in if condition.

Thanks ,

Handle WM_QUERYENDSESSION message is your application. return FALSE to stop the shutdown of logoff process.

if (message == WM_QUERYENDSESSION)  
{
if(allow)
{
return TRUE;
} 
else
{
return FALSE;
}
}

overide the WM_QUERYENDSESSION message and return 0. And after you have done your time interval call ExitWindows() to shutdown.

Hello,

I have a tricky problem and I hope anyone can point me a solution. I have an C++ Unicode application that received a parameter form the browser. If the parameter is a Greek word for example, I get something like this &u=%u03C5%u03B2%u03AD& (html entities). Does anyone know an efficient method to convert the html entity into the Greek character?

Thanks.
