Title: Is it safe to use Database in the Initialize() method?
Post by: Andrey Bushman on May 15, 2015, 09:56:04 AM
When I do it, then my code looks something like this:
Code - C#: [Select]
  1. public void Initialize() {
  2.   Document doc = cad.DocumentManager.MdiActiveDocument;
  3.   if (null == doc)
  4.     return;
  5.  
  6.   Database db = doc.Database;
  7.   Editor ed = doc.Editor;
  8.  
  9.   using (doc.LockDocument()) {
  10.     using (Transaction tr = db.TransactionManager.StartTransaction()) {
  11.       ed.WriteMessage("\nThe \"{0}\" assembly successfully loaded.\n",
  12.         this.GetType().Assembly.Location);      
  13.       // TODO: Here is my code of working with Database...
  14.       tr.Commit();
  15.     }
  16.   }
  17. }
Assembly can be registered for autoloading (through the registry record or BUNDLE engine). I hadn't problems with such approach, but I remember - Alexander Rivilis wrote he had. He wrote what the Document (or Database) can be initialized not completely at the time of operation of this code. Ok, how can I check initialization of these objects was finished?

P.S. The "Spell Chek" button in the edition mode doesn't work, I see an empty window.

I do mine in a static constructor of class with PerDocData attribute and not had a problem

PerDocData attribute
What is it? I can't find info about it in ObjectARX SDK and MSDN.

But this attribute was introduced only in AutoCAD 2015.
