System.NullReferenceException

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   When I have modify the property of the object I get the following error: system.nullreferenceexception 'object reference not set to an instance of an object.'

The properties are:
CommandBars.ActiveMenuBar.Closeable = True
CommandBars.ActiveMenuBar.ShowGripper = False
CommandBars.ActiveMenuBar.ShowExpandButton = False
CommandBars.ActiveMenuBar.Customizable = False
CommandBars.ActiveMenuBar.EnableAnimation = True
Etc...

Another error occurs in the DockingPane component. When I have modify the property of the object I get the following error: system.accessviolationexception 'attempted to read or write protected memory.

The properties are:
DockingPane .PaintManager.CaptionFont.Name = "Segoe UI"
DockingPane .PaintManager.SplitterSize = 5
DockingPane .TabPaintManager.ButtonMargin.Bottom = 3

Etc...

I'm using VB.NET (VS 2019). Is it an incompatibility with .net framework? Can someone help me?
