What is the system variable for displaying scroll bar in drawing?

[Anonymous]

Hey,

Anyone know?

I'm asking about this:

Thanks.

Not everything is controlled by system variables.

For this aspect, you need to access the display preferences.  Look at the ActiveX  Object Model (ActiveX) http://help.autodesk.com/cloudhelp/2016/ENU/AutoCAD-ActiveX/files/GUID-A809CD71-4655-44E2-B674-1FE20...

There are helper functions to work with the activex object properties and methods.  These will gain control over many parts of AutoCAD

For example:

(setq displaypref
		   (vla-get-display
		     (vla-get-preferences
		       (vlax-get-acad-object))))

(vla-get-displayscrollbars displaypref)

(vla-put-displayscrollbars displaypref :vlax-true)

;Alternatively you can use :vlax-false to turn them off.

I've found the solution with your help 🙂

AcadPreferences Preferences = (AcadPreferences)Autodesk.AutoCAD.ApplicationServices.Application.Preferences;

Preferences.Display.DisplayScrollBars = false;

Do you know why I'm getting an error when I want to set Taskbar = 0;

Autodesk.AutoCAD.ApplicationServices.Core.Application.SetSystemVariable("TASKBAR", 0);

"An exception of type 'Autodesk.AutoCAD.Runtime.Exception' occurred in accoremgd.dll but was not handled in user code"

Please note: This is a visual lisp newsgroup.  When you ask a question without specifying the customization language, you will get Visual Lisp as a response.  There is a VBA newsgroup that you can post VBA questions on.  I do not have the visual basic plug-in for AutoCAD at my current location so cannot answer your question.  If it remains unanswered tonight, I will let you know.

This code works. Your code snippet looked a bit weird unless I am mistaken about it being VBA. If you need .NET code, visit the .NET newsgroup.  Hope this helps.

Option Explicit
Sub nobars()
Dim dpref As AcadPreferencesDisplay
Set dpref = Application.Preferences.Display
dpref.DisplayScrollBars = False
End Sub

Sub bars()
Dim dpref As AcadPreferencesDisplay
Set dpref = Application.Preferences.Display
dpref.DisplayScrollBars = True
End Sub

Thank you very much for help. I've made a mistake and choose wrong category 🙂

In case of TASKBAR - this is not system variable, just want to write if something will search for it.

OK, glad to help.

Taskbar is not a system variable.  It is a command.  It should not have any relevance however in Window 8 or higher and should not have any relevance in the CORE console because that is a background process that would not have a taskbar presence anyway.  The core console if a non-interactive environment for creating/editing drawings.
