 i get the error in line in red

please help me.



Public Sub InsertDrawing(ByVal dwgName As String, ByVal insPt As AcGe1.Point3d, ByVal s3d As AcGe1.Scale3d, ByVal rot As Double)
        Dim blkName As String = Path.GetFileNameWithoutExtension(dwgName)
        Using db As Database = AcDb1.HostApplicationServices.WorkingDatabase()
            Using tr As Transaction = db.TransactionManager.StartTransaction
                    Dim id As ObjectId = Nothing
                    Using bt As BlockTable = tr.GetObject(db.BlockTableId, OpenMode.ForRead, True)
                        If Not bt.Has(blkName) Then
                            Using sourceDb As Database = New Autodesk.AutoCAD.DatabaseServices.Database(False, True)
                                sourceDb.ReadDwgFile(dwgName, FileOpenMode.OpenForReadAndAllShare, True, "")
                                id = db.Insert(dwgName, sourceDb, False)
                                Dim blk As BlockTableRecord = tr.GetObject(id, OpenMode.ForWrite, False, True)
                                blk.Name = blkName
                            End Using
                            id = bt.Item(blkName)
                        End If
                    End Using
                    Dim btr As BlockTableRecord = tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite, True)
                    Dim bref As BlockReference = New BlockReference(insPt, id)
                    bref.ScaleFactors = s3d
                    bref.Rotation = rot
                    Dim ObjColl As DBObjectCollection = New DBObjectCollection()
                    For Each acEnt As Entity In ObjColl
                        tr.AddNewlyCreatedDBObject(acEnt, True)

My guess is that the blkname it's not a valid block name, because it has "\" in the name. try getting just the blockname from dwgname without the file path in it.

This should not change because the VB version, maybe between AutoCAD versions or the file permission.


Can you quick try the last parameter as TRUE? Use as FALSE is not a easy way, check out the help file.

Dim id As ObjectId = Nothing is it true in VB.NET. because in C# ObjectId is a struct thus a ValueType descendant so must be initialized like

ObjectId id = ObjectId.Null;

 i am just asking because i am not very good at VB.NET.


and did you try the overload of ReadDwgFile like this
