Hi,
I have a Probleme with the PostMLeaderStyleToDb Method, this make me an error but I can't identify them while the debugger spring.
Here my code:

public void LoadImportedMLeaderStyle()
{
List<AcDataService.MLeaderStyle> mlStyles = new List<AcDataService.MLeaderStyle>();
var doc = AcAp.Application.DocumentManager.MdiActiveDocument;
AcDataService.Database acCurDb = doc.Database;
Dictionary<string, AcDataService.MLeaderStyle> mlStyleDico = new Dictionary<string, AcDataService.MLeaderStyle>();
string dwgFilePath = Symbol.RichtungsPfeileOrSonstigesOrRSADWGPath(Symbol.mLeaderStyleDWGFileName);
if (File.Exists(dwgFilePath))
{
try
{
using (var trans = doc.TransactionManager.StartTransaction())
{
using (AcDataService.Database sourceDb = new AcDataService.Database(false, true))
{
//load MLeaderStyle aus DWG
sourceDb.ReadDwgFile(dwgFilePath, FileShare.Read, false, null);
sourceDb.CloseInput(true);
using (var transsourcedb = sourceDb.TransactionManager.StartOpenCloseTransaction())
{
//Suche die MLeaderStyle
var mlStyleImport = (AcDataService.DBDictionary)transsourcedb.GetObject(sourceDb.MLeaderStyleDictionaryId, AcDataService.OpenMode.ForRead);

                    //Load die aktuell MLeaderStyle aus Current DB
                    AcDataService.DBDictionary mlStylesAktuell = (AcDataService.DBDictionary)trans.GetObject(acCurDb.MLeaderStyleDictionaryId, AcDataService.OpenMode.ForRead);

                    foreach (AcDataService.DBDictionaryEntry entry in mlStyleImport)
                    {
                       AcDataService.MLeaderStyle mls = (AcDataService.MLeaderStyle)transsourcedb.GetObject(entry.Value, AcDataService.OpenMode.ForRead);
                       if (mls != null)
                       {
                          if (!mlStylesAktuell.Contains(mls.Name))
                          {
                             var mlsClone = mls.Clone() as AcDataService.MLeaderStyle;
                             //Gibt den Clone als neue MLeaderStyle an den Current DB
                             mlsClone.PostMLeaderStyleToDb(acCurDb, mls.Name);
                             trans.AddNewlyCreatedDBObject(mlsClone, true);
                          }
                       }
                    }
                    transsourcedb.Commit();
                 }
              }
              trans.Commit();
           }
        }
        catch(Exception ex)
        {

        }
     }

    You cannot insert a cloned object into another database. The object is full of links to another database. It doesn't work that way. Copying between drawings is done only by the WblockCloneObjects method

    just like example:

        private static void DimStylesImport(Database targetDb, string fileName, string[] DimStylesNames, DuplicateRecordCloning behaviour)
    {
      using Database sourceDb = DocExt.GetDocDatabase(fileName);
      if (sourceDb is null) return;
      if (sourceDb == targetDb) return;        // вызов метода из самого файла шаблона
      ObjectIdCollection dimIds = new ObjectIdCollection();
      using (Transaction sourceTr = sourceDb.TransactionManager.StartTransaction())
      {
        DimStyleTable dst = sourceTr.GetObject(sourceDb.DimStyleTableId, OpenMode.ForRead) as DimStyleTable;
        foreach (string dimName in DimStylesNames)
          if (dst.Has(dimName))
            dimIds.Add(dst[dimName]);
        sourceTr.Commit();
      }

      IdMapping mapping = new IdMapping();
      sourceDb.WblockCloneObjects(dimIds, targetDb.DimStyleTableId, mapping, behaviour, false);
    }

    Hi avc,
    thanks for your help.
    With the WBlockCloneObjects it's working perfect.

    Thanks
