Advance Steel 2019 API Selection method

[NinovSM]

This simple C# code returns null for "ASobject" variable in AS2019. In previous AS versions works correctly.

Autodesk.AdvanceSteel.CADLink.Database.ObjectId objId = UserInteraction.SelectObject();
AtomicElement ASobject = DatabaseManager.Open(objId) as AtomicElement;

 What is the reason?

Hi,

startoing in AS 2019 you need to start a transaction and access objects inside of a transaction. Before AS2019 with the calling of an Advance Steel API command implicitly a transaction was started at command start and committed at command and. That is now up to you. So use code like

    Public Shared Sub GetReprType()

        Dim tObjId As ObjectId = UserInteraction.SelectObject
        If tObjId IsNot Nothing Then
            DocumentManager.LockCurrentDocument()
            Using tTrans As Transaction = TransactionManager.StartTransaction
                Try
                    Dim tFilerObj As FilerObject = DatabaseManager.Open(tObjId)
                    Dim tReprObjId As ObjectId = DatabaseManager.GetReprId(tFilerObj)
                    Dim tAcObjId As New DatabaseServices.ObjectId(tReprObjId.AsOldId)
                    Dim tReprName As String = tAcObjId.ObjectClass.Name
                    Debug.Print("")
                    MsgBox(tReprName)
                Catch ex As Exception
                Finally
                    tTrans.Commit()
                End Try
            End Using
            DocumentManager.UnlockCurrentDocument()
        End If
    End Sub

By the way: If you select Acad entities with userinteraction metrhod, their ADVS ObjectId will be null.

Hi, Christian

Thanks for answer.

But as I know your code for VB.NET. My question about C#

Hi,

there are code translators, that you can find in the net that help to translate between VB and C#.

• https://www.carlosag.net/tools/codetranslator
• http://converter.telerik.com/

The code inC# would be like

    class Test
    {
        public static void GetAtom()
        {
            ObjectId tObjId = UserInteraction.SelectObject();
            if (tObjId.IsNull()== false)
            {
                DocumentManager.LockCurrentDocument();
                using  (Transaction tTrans = TransactionManager.StartTransaction())
                {
                    try
                    {
                        FilerObject tFilerObj = DatabaseManager.Open(tObjId);
                        if (tFilerObj.IsKindOf(FilerObject.eObjectType.kAtomicElem))
                        {
                            AtomicElement tAtom = (AtomicElement)tFilerObj;
                        }
                    }
                    catch (Exception ex)
                    {
                    }
                    finally
                    {
                        tTrans.Commit();
                    }
                }
                DocumentManager.UnlockCurrentDocument();
            }
        }
    }

Yeah, problem in Transaction. With transaction works good.
