SW_HIDE and CScrollView

Hallo,I have created a class derived from CStatic, and I have added a member to this class, a CScrollView.
I have created this CScrollView (m_scroll) without showing it until it is necessary.
I show it with m_scroll.ShowWindow(SW_SHOW).
After this, I have had to not show the scroll, so I have done
m_scroll.ShowWindow(SW_HIDE), but this doens't work, the scroll remains visible, although not active.
I also have tried to change the m_scroll zorder, but nothing.
I don't understand what's the problem.
Is there anyone who could help me?
Thank's

Re: SW_HIDE and CScrollView

Have you tried to update the window using UpdateWindow method? If not try invoking UpdateWindow after ShowWindow

Thanks,

Re: SW_HIDE and CScrollView

Are you trying to hide ScrollView or scrollbar in ScrollView?

Try calling ShowScrollBar() method.

Re: SW_HIDE and CScrollView

From starting, you are on a wrong path.
A scroll view (implemented by CScrollView), like any other type of view, is designed to sit in a frame window, with the respect of SDI/MDI architecture and NOT in a static control (implemented by CStatic).

What you really want to accomplish? It seems, you have added that scroll view in a static control in order to "manage scroll bars". Am I right?

That sounds like a very odd thing to do. Did you add some kind of frame for the view?

Is it so much time between having that problem and posting this topic, or we are just shooting in the dark? :rolleyes:
Well, not even putting a scrollbar control in a static contol is a brillant ideea.

A scrollbar control (implemented by CScrollBar) is designed, like most of other controls, to sit in a dialog.

If you want to manage scrollbars in the static contol, you have to derive from CStatic, use scrollbar-related functions and handle WM_HSCROLL and/or WM_VSCROLL messages.
