Hi,

I'm not very cumfortable with VB but this line hurts me:

openFile1.InitialDirectory = "C\"

If this is not the source of the error, could you say which line throws the "invalid input error" error.

[yoitsarun]

error message is from here:

Try
     bDwg.Database.BindXrefs(XrefIds, False)
     Catch ex As Exception
     MsgBox("Error: " & ex.Message)
End Try

[yoitsarun]

one more thing this code is working if i run individually (not as batch).

[_gile]

To know the line the error occured, you can try replacing the Catch block with this:

Try
     bDwg.Database.BindXrefs(XrefIds, False)
     Catch ex As Exception
     MsgBox("Error: " & ex.Message & vbCr & ex.StackTrace)
End Try

[yoitsarun]

error is:

 

[_gile]

The error is due to line 183 in the file BatchXrefBind.vb.

[yoitsarun]

yes, but i dont know what is the error in this code

bDwg.Database.BindXrefs(XrefIds, False)

[_gile]

The error is probably due the the contents of XrefIds.

Pay attention to what's said i the documentation for the BindXrefs method:

"The object IDs in xrefIds must all be from the database and they must all be resolved."

It seems to me bDwg is the active document (i.e. the document where the command was launched) and XrefIds contains objectIds from the opened in memory database.

[yoitsarun]

something wrong in active document ?

I am new to this, but I did xref bind program in editor using same code and it works.

How it will work in memory database, if you know something please help me.

If you are in familiar in c# it is ok. I can convert.

[_gile]

"The object IDs in xrefIds must all be from the database" i.e., the database you create 'in memory' (db). 

Try:

db.BindXrefs(XrefIds, False)

[yoitsarun]

I tried this, but no luck, same "error: invalid input"

[_gile]

Try like this (not tested)

using System.Windows.Forms;

using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.Runtime;

using AcCoreAp = Autodesk.AutoCAD.ApplicationServices.Core.Application;

namespace BindXrefsSample
{
    public class Commands
    {
        [CommandMethod("TEST1")]
        public static void BindXrefsInCurrentDrawing()
        {
            BindXrefs(HostApplicationServices.WorkingDatabase);
        }

        [CommandMethod("TEST2")]
        public static void BindXrefsInDwgFiles()
        {
            var ofd = new OpenFileDialog{
                InitialDirectory = "C:\\",
                Filter = "Drawing files|*.dwg",
                Multiselect = true};
            if (ofd.ShowDialog() == DialogResult.OK)
            {
                foreach (string fileName in ofd.FileNames)
                {
                    using (var db = new Database(false, true))
                    {
                        db.ReadDwgFile(fileName, FileOpenMode.OpenForReadAndAllShare, false, null);
                        BindXrefs(db);
                        db.SaveAs(fileName, true, db.OriginalFileVersion, db.SecurityParameters);
                    }
                }
            }
        }

        private static void BindXrefs(Database db)
        {
            try
            {
                var xrefIds = new ObjectIdCollection();
                using (var tr = new OpenCloseTransaction())
                {
                    var bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
                    foreach (ObjectId id in bt)
                    {
                        var btr = (BlockTableRecord)tr.GetObject(id, OpenMode.ForRead);
                        if (btr.IsFromExternalReference && btr.IsResolved)
                            xrefIds.Add(id);
                    }
                }
                db.BindXrefs(xrefIds, false);
            }
            catch (System.Exception ex)
            {
                AcCoreAp.ShowAlertDialog("Error: " + ex.Message);
            }
        }
    }
}

[_gile · Accepted solution]

This version of the BindXrefs() method resolves the xrefs in the database before binding them.

        private static void BindXrefs(Database db)
        {
            var workingDb = HostApplicationServices.WorkingDatabase;
            HostApplicationServices.WorkingDatabase = db;
            try
            {
                db.ResolveXrefs(true, false);
                var xrefIds = new ObjectIdCollection();
                using (var tr = new OpenCloseTransaction())
                {
                    var bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
                    foreach (ObjectId id in bt)
                    {
                        var btr = (BlockTableRecord)tr.GetObject(id, OpenMode.ForRead);
                        if (btr.IsFromExternalReference && btr.IsResolved)
                            xrefIds.Add(id);
                    }
                }
                db.BindXrefs(xrefIds, false);
            }
            catch (System.Exception ex)
            {
                AcCoreAp.ShowAlertDialog("Error: " + ex.Message);
            }
            finally
            {
                HostApplicationServices.WorkingDatabase = workingDb;
            }
        }
