Title: eLockViolation of blocktable
Post by: mohnston on January 08, 2007, 08:08:43 PM

Why would I get an error that says eLockViolation on the line "BlockTable bt = (BlockTable)thisDB.BlockTableId.GetObject(OpenMode.ForWrite);"
???

Code: [Select]

private void StampDrawing(string fullDwgPath, string stampString, bool FullSize)
{
   Document ThisDrawing = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.Open(fullDwgPath);
   Database thisDB = ThisDrawing.Database;
   Autodesk.AutoCAD.ApplicationServices.TransactionManager tm = ThisDrawing.TransactionManager;
   using (Transaction trans = tm.StartTransaction())
   {
      BlockTable bt = (BlockTable)thisDB.BlockTableId.GetObject(OpenMode.ForWrite);
      BlockTableRecord modelsp = (BlockTableRecord)trans.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);
      DBText stampText = new DBText();
      stampText.TextString = stampString;
      stampText.Height = 12;
      stampText.HorizontalMode = TextHorizontalMode.TextRight;
      stampText.Rotation = 0;
      modelsp.AppendEntity(stampText);
      trans.TransactionManager.AddNewlyCreatedDBObject(stampText, true);
      trans.Commit();
   }
   tm.Dispose();
   ThisDrawing.CloseAndSave(fullDwgPath);
   thisDB.Dispose();
}

The file opens fine but I am unable to get the blocktable.

What is your
[CommandMethod(..... CommandFlags.XXXX

.. is it set to .Session ??    IE Application context

changing the database in Session mode without locking the database may be the issue

You are correct. The code was being launched from a dialog button.

I added the Document.LockDocument() and the error went away.

Thank you!

Sadly, my text does not appear on that drawing.
