Title: Closed filled arrowhead bug
Post by: samideqlqpart on December 25, 2016, 02:31:04 AM

Hello and happy new year
when i ran my program i got this message

eInvalidInput
at
Autodesk.AutoCAD.ApplicationServices.Core.Application.SetSystemVariable(String name, Object value)
at this line
Autodesk.AutoCAD.ApplicationServices.Application.SetSystemVariable("DIMBLK", "_Closedfilled")

but it's happened only with the closed filled arrow and works well with ALL other types of the arrowhead
like  _Dot, _Closedblank,.......

here is the code


                ' Make the arrow head as _Closedfilled.

                Dim mldstyle As New MLeaderStyle()

                Dim blockTable As BlockTable = tr.GetObject(db.BlockTableId, OpenMode.ForRead)
                If (Not blockTable.Has("_Closedfilled")) Then
                    ' load the "_DOT" block definition
                    Autodesk.AutoCAD.ApplicationServices.Application.SetSystemVariable("DIMBLK", "_Closedfilled")
                End If

                mldstyle.ArrowSymbolId = blockTable("_Closedfilled")

How to fix it?
and if the answer is to load it at the begin, then how to do it?
i'm needing helps

thank you

What does this do for you ?

Code: [Select]

Command:
DIMBLK
Enter new value for DIMBLK, or . for default <"">:



and the matching instruction in code
something like :

Code - C#: [Select]

1.  
2.             arrowName = (string)AcadApp.GetSystemVariable("DIMBLK");
3.             ed.WriteMessage($"\nDIMBLK is: {arrowName} \nID is: {db.Dimblk}\n");
4.  
5.             // Set to default 'Closed filled'
6.             db.Dimblk = ObjectId.Null;
7.  
8.             arrowName = (string)AcadApp.GetSystemVariable("DIMBLK");
9.             ed.WriteMessage($"\nDIMBLK is: {arrowName} \nID is: {db.Dimblk}\n");
10.  
11.
