Topic: What’s the best way to import a text style from a dwt in the support path?

What’s the best way to import a text style from a dwt in the support path into the active drawing?

I’ve got a dwt template in my dll directory that has layers, blocks, textstyles, etc that I would like to use in my app. This allows users to modify the blocks, etc to customize their drawings. It also keeps me from hardcoding the blocks, styles, etc. The dwt file is in the support path.

Is WblockCloneObjects the best way to do this for textstyles too?

Right now I import blocks with the following:

Code - C: [Select]

1. /// <summary>
2. /// Gets the block from specified drawing and adds it to the blocktable of the active drawing..
3. /// </summary>
4. /// <param name="blockName">The blockname.</param>
5. /// <param name="path">The path to dwg/dwt to extract block from.</param>
6. private static bool GetBlockFromDWG(string blockName, string path)
7. {
8.    using (Database openDb = new Database(false, true))
9.    {
10.       openDb.ReadDwgFile(path,
11.          System.IO.FileShare.ReadWrite, true, "");
12.  
13.       ObjectIdCollection ids = new ObjectIdCollection();
14.       using (Transaction tr = openDb.TransactionManager.StartTransaction())
15.       {
16.          var bt = (BlockTable)tr.GetObject(openDb.BlockTableId, OpenMode.ForRead);
17.  
18.          if (bt.Has(blockName))
19.          {
20.             ids.Add(bt[blockName]);
21.          }
22.          tr.Commit();
23.       }
24.  
25.       //if found, add the block
26.       if (ids.Count != 0)
27.       {
28.          //get the current drawing database
29.          Active.Document.LockDocument(DocumentLockMode.ProtectedAutoWrite, null, null, true);
30.          IdMapping iMap = new IdMapping();
31.          Active.Database.WblockCloneObjects(ids, Active.Database.BlockTableId
32.             , iMap, DuplicateRecordCloning.Ignore, false);
33.          return true;
34.       }
35.       else
36.       {
37.          return false;
38.       }
39.    }
40. }
41.

Yes,
good for any TableRecord imports.

Don't forget to post your code when you're done.

Thanks for the feedback Kerry. I ended up using WblockCloneObjects. Worked a treat.

Here's my code. I have something similar for blocks.

Code - C: [Select]

1. /// <summary>
2. /// Checks if the style definition is in the active drawing, if not, pull it from the template and add it
3. /// </summary>
4. /// <param name="styleName">Name of the style.</param>
5. /// <returns>ObjectID of Textstyle, ObjectId.Null on error</returns>
6. public static ObjectId GetStyleId(String styleName)
7. {
8.     ObjectId styleId = ObjectId.Null; ;
9.     ObjectIdCollection ids = new ObjectIdCollection();
10.     using (Transaction acTr = Active.TransactionManager.StartTransaction())
11.     {
12.         TextStyleTable styleTable = (TextStyleTable)acTr.GetObject(Active.Database.TextStyleTableId, OpenMode.ForRead);
13.         if (styleTable.Has(styleName))
14.         {
15.             styleId = acTr.GetObject(styleTable[styleName], OpenMode.ForRead).ObjectId;
16.             acTr.Commit();
17.             return styleId;
18.         }
19.         acTr.Commit();
20.     }
21.     // it's not in active drawing, try to pull it from the template dwt
22.     string dllPath = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
23.     String dwtPath = dllPath + AID_Default.TemplatePath;
