AutoCAD Drawing Tables

Question

I am trying to get my C # .NET Plugin to draw a table in AutoCAD with .NET-based information that users fill out. The code I use for this is based on this page . By changing it for my plan, the code looks like this:

using System; using System.Collections.Generic; using System.Linq; using System.Text; using Autodesk.AutoCAD.ApplicationServices; using Autodesk.AutoCAD.DatabaseServices; using Autodesk.AutoCAD.EditorInput; using Autodesk.AutoCAD.Geometry; using Autodesk.AutoCAD.Runtime; namespace WindowsDoors.NET { class OpeningDataTable : Table { private int rowCount = 0; private static Document doc = Application.DocumentManager.MdiActiveDocument; //Current drawing private static Database db = doc.Database; //subclass of Document, private static Editor ed = doc.Editor; //Editor object to ask user where table goes, subclass of Document public OpeningDataTable(bool isWindow) { PromptPointResult pr = ed.GetPoint("\nEnter table insertion point: "); if (pr.Status == PromptStatus.OK) { //Setting information about the table TableStyle = db.Tablestyle; SetSize(2, 5); SetRowHeight(3); SetColumnWidth(15); Position = pr.Value; //Creating titles to add String[] columnTitles = new String[5]; columnTitles[0] = "Mark"; columnTitles[1] = "Width"; columnTitles[2] = "Height"; columnTitles[3] = "Header\nMaterial"; columnTitles[4] = "Packers\n(Each Side)"; //Adding titles to table addRow(columnTitles); } } public void addRow(String[] data) { // Use a nested loop to format each cell for (int i = 0; i < data.Length; i++) { ParseOption s = new ParseOption(); Cells[rowCount, i].TextHeight = 1; Cells[rowCount, i].SetValue(data[i], s); } GenerateLayout(); Transaction tr = doc.TransactionManager.StartTransaction(); using (tr) { BlockTable bt = (BlockTable)tr.GetObject(doc.Database.BlockTableId, OpenMode.ForRead); BlockTableRecord btr = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite); btr.AppendEntity(this); tr.AddNewlyCreatedDBObject(this, true); tr.Commit(); } } } } 

This problem occurs at the bottom of this line.

 (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite); 

It says that BlockTableRecord does not have a ModelSpace extension, although I accepted this right in the example below. I need to know if there is a way to fix this, or if it has been replaced with something else.

Answer 1

I get it. Since I am extending the Table class that has a BlockTableRecord field, I had to be more specific

 BlockTableRecord btr = (BlockTableRecord)tr.GetObject(bt[Autodesk.AutoCAD.DatabaseServices.BlockTableRecord.ModelSpace], OpenMode.ForWrite);
