I got here to ask this question because none of the solutions I've found satisfied me or even worked. My problem is pretty straightforward.
I have a CListCtrl in C++ with a lot of columns. They don't fit to the width of the list, so I have to add a horizontal scroll bar.
I tried with EnableScrollbar, ShowScrollBar, SetScrollPos, but none of them worked. How do I create a horizontal scrollbar and show it properly?
If you are using the LVS_REPORT style it should just add the scrollbar for you (as long as the columns exceed the width of the ListCtrl). No special trickery needed.
Is it possible that your CListCtrl is sized bigger than it's container window and therefore not adding a scrollbar? If it's still not working please add a screenshot to your question.

I am using MVC for my project. And I have few views in View. However, I want to know how to add a scrollbar to one view and only make that part can be scrolled vertically.
I have tried using CreateWindowW() for adding WM_VSCROLL parameter, but it does not work.
This is a TUI application, so I think the professor try to make us using a cell as bar, so you can scroll the cell up and down
In PreCreateWindow(CREATESTRUCT& cs), set cs.style |= WS_VSCROLL;.
You may have to respond to WM_VSCROLL to process scroll messages.
Sorry for the confusing. I am resisted to use TUI only. And I misunderstood what the professor needed. So he wanted us to move a color cell so you can scroll up and down for checking player's moves. I am making a Gomoku Game by using C++. So I figure it out, right now my move list view can move up and down for viewing full moves. Thanks for all the answers

My app needs to be small in nature so I make it 500 x 100 px in size.
The problem is the ComboBox selection items are also squeezed into that small window size. Of course, I can scroll it, but it doesn't feel right this way.
Here is the picture:
Is it possible to expand the ComboBox selection list so that it exceeds the parent window? Preferably in XAML if possible
Is it possible to expand the ComboBox selection list so that it exceeds the parent window?
No, this is impossible in UWP apps. While using ComboBox class, it displays the drop-down list in PopupRoot, which is a layer has the same view port as its parent window. Anything outside this view port will be clipped, users can't see them. For example, following is a normal ComboBox:
After I give a Margin="-20,-30,0,0" to the drop-down list, it looks like
The part outside the window is clipped.
Besides, The implementation of ComboBox will also make sure the ComboBox's selection list won't exceeds the parent window. The selection list's max height is calculated at runtime, it will be always less than the parent window's height and we can't change its value manually, so it is not possible to expand the ComboBox's selection list.
It's not possible, but you can extend your page to the title bar to have at least some additional space using CoreApplicationViewTitleBar.ExtendViewIntoTitleBar property.
Take a look here and here. (I know the examples are written in C# but it should be similar in C++)
I have a window structured in the following manner:
Window>VBox>Scrolled Window>Tree View>Columns
My issue arises when I label the last column (it must be a dynamic assignment). If the label winds up being too long, the containing window gets stretched horizontally. Instead, I would like a scroll bar to appear at the bottom of the Scrolled Window to deal with it, leaving the window at its original width.
However, it looks like the closest I can come is fixing the height of the Tree View. Surely there's a way to fix the width?
Do you have some code to look at? I have done this many times in python and never had any trouble. Also, you link to the fixed height property of the Tree View rows, you actually need the requested width property of the scrolled window. That link also has a link to set the size of the window.
I'm trying to make a questionnaire with Qt, using Qt Designer to design the forms.
I want to display each question and the possible answers on a line, one question under the previous one. The problem is that I've got too many question to fit in my window.
I tried using qtscrollarea but I can't manage to get the scroll bars....
I am using QtDesigner, I put a qtscrollarea, with a vertical layout in it, adding the QWidgets containing question and answers in the vertical layout. I tried to force the vertical layout to be bigger than the qtscrollarea, tried to change somme Qwidget to horiontal layout, taking off the vertical layout... But still no way to have a scroll bar.
Any advice on a way of doing it through QtDesigner?
Try this:
place a qtscrollarea
place in qtscrollarea widgets containing question and answers
right click on qtscrollarea and select layout, vertical in your case
I have a member of CWnd class name mywindow

mywindow.EnableScrollBar(SB_BOTH,ESB_ENABLE_BOTH);
and it change nothing.
can someone could show me a simple example how to add scroll-bar to this member?
thanks a lot,

Enabling the scroll bars isn't enough. You have to react to the window messages WM_HSCROLLand WM_VSCROLL. Using the GetScrollInfo method you get the position (value) of the scroll bars and then you draw your window content according to this position.
Look up some scroll bar tutorials such as http://www.codeproject.com/KB/dialog/scrolling_support.aspx . In essence, dwo's comment above is what you need to do - handle those messages and set the virtual client area size.
There must be some 'overflow' before scroll bars became active.
Write some 'sufficiently long' data in your view and the scrollbars will become active (at least, that was my experience time ago).
Usually scroll bars get handled 'automatically' from MFC components like (for instance) text editor or form view. I.e. will became visible when needed also without explicit call EnableScrollBarCtrl ...
