change image in a picturebox on scroll in C++/CLI - scroll

I have a form application in C++ CLI. It has a scroll bar. I have a panel inside form and a number of picture boxes in it. The panel has auto scroll set. Is it possible that I can hide the panel auto scroll bar and control its scrolling by the form scroll bar.
The form screen shot is attached here
I tried changing the VerticalScroll.Visible property of the panel. But it doesn't help.
regards,

Xcode - Hide View Controller Scene Panel

I am completely new to Xcode. I would like to hide the View Controller Scene panel, so that I can follow on with a tutorial, and have more screen real estate. I understand that I can hide the left and right panels, but it's the panel I have highlighted in red which I want to hide. Many thanks.
There's a small icon representing that panel at the bottom of the storyboard view. It's just to the left of the spot that says "View as: iPhone 8..." in your image. Click that icon to toggle the visibility of the storyboard outline view.
There's also a menu command: Editor->Hide Document Outline that does the same thing.
Press the highlighted icon to hide the side panel.
For xcode 11.3 you may hide the preview by
Editor->Preview
make sure it is not checked.

How to disable markup option on images in NSTextView?

I have an NSTextView, which has graphics enabled so that users can drag images into it. The problem is that it has an arrow on the image, which opens a dropdown menu. Is there a way to disable this menu, because it causes problems within my app.
How about NSTextView's allowsImageEditing property?
Set it to "false".

Scroll View and Toolbar

In Xcode 6, I am designing an app whose view has a scroll view and a toolbar. However, when I run my app in iOS Simulator, the toolbar stays where it was placed in interface builder and does not stay directly at the bottom as I scroll. How can I fix this?
Thanks for your help.
Have you placed the toolbar inside the scroll view? If so, you will want to move it outside of the scroll view and anchor it instead at the bottom of the parent view. Then you will want to reduce the size of your scroll view so that it does not get cut off by the toolbar.
