Problem when I try to touch ObjectData twice in a row in the same C3D session with C#.Net

[m.chavet7MJRB]

Hello,

I created a post a few months ago at this location: https://forums.autodesk.com/t5/net/bug-when-successively-launching-a-function-i-ve-created/m-p/12340... , which I validated too quickly by mistake... As it happens, the problem still persists.

In the same project session, when I try again to touch ObjectData (by importing them, or if I want to reread the "records" a second time), I always get the error :

Application does not support just-in-time (JIT)
debugging. See the end of this message for details.

Here is the first code to import shapefile:

[CommandMethod("SHP2")]
static public void SHP2()
{
      Autodesk.AutoCAD.Windows.OpenFileDialog ofd = new Autodesk.AutoCAD.Windows.OpenFileDialog(
          "Select SHP File", null, "shp", "Select shp", Autodesk.AutoCAD.Windows.OpenFileDialog.OpenFileDialogFlags.AllowAnyExtension);
      if (ofd.ShowDialog() == DialogResult.OK)
      {
          string shpname = ofd.Filename;
          Import2(shpname);
      }// 
}//acad command - SHP2

private static void Import2(string shpname)

    MapApplication mapApp = HostMapApplicationServices.Application;
    Importer importer = mapApp.Importer;
    try

        importer.Init("SHP", shpname);
        foreach (InputLayer il in importer)
        {
            il.SetLayerName(LayerNameType.LayerNameDirect, fname);
            il.SetDataMapping(ImportDataMapping.NewObjectDataOnly, fname);
        }// foreach shp layer

        ImportResults ir = importer.Import(true);
    }
    catch { }
    finally { };
}// Import2

Problem is at : 

il.SetDataMapping(ImportDataMapping.NewObjectDataOnly, fname);

And for the second :

Problem is at the last line

                return profileObjectIdMap;
            }
    }            

}

"Records" can be opened several times in a row when I run a function with a loop.

However, if a function is run a second time, independently of the first time, I get the error mentioned above.

It seems that this is due to the fact that the "records" extracted from the "tables" are empty during the second independent execution. I don't understand why, in the same session, the "records" become "empty" after being opened the first time, whereas if I run the same function in a new 3D civil session, everything works.

I hope my problem is clear to anyone reading this...

[fieldguy]

You can't run the importer on the same file more than once. My guess is a duplicate records problem. If you use "mapimport" from the command line, acad happily creates duplicates. The managedmap api import does not (again - my guess is the "NewObjectDataOnly" property).

In the second "records" issue, you need to check that records.Count > 0 before the foreach. Again - my guess is an entity in the selection does not return any records.

In the future, include complete code samples and data if you can (you may have your own small set of test data?), with what you are trying to achieve - before and after. 

[m.chavet7MJRB]

Thank you for your reply

I can't even import different files (not necessarily the same) in the session C3D session..

Yes, indeed, records are empty in the next launch although OD of all the geometries are still present in C3D after a first launch. But with the same geometries selected, the read of OD work the first time.  I tried to (re)add and update record/records in the table/tables :

tables.UpdateTable(table.Name, table.FieldDefinitions);
table.AddRecord(record,so.ObjectId);

records.UpdateRecord(record);

tables.Add(table.Name, table.FieldDefinitions, "blabla", true);

it doesn't work and the error is the same than mentionned before

And: 

il.SetDataMapping(ImportDataMapping.ExistingObjectDataOnly, fname);

Here is some data in shapefile: https://we.tl/t-v5CpnAEEc1

So, the idea may be to duplicate and register "records" somewhere else?

[fieldguy]

Check the following against yours - or just try mine.  You can import multiple shp files as long as the data does not exist.  I don't understand why you would want to import the same data again. 

Also - List<ObjectId> should just be ObjectId - no list required (1 to 1 relationship entity to OD record)

[fieldguy]

That code isn't %100 correct.  It is using the field definitions to determine if the field name is "Profil".  You are not guaranteed that field name doesn't exist in some other table.  IMO you should check the table name first, before getting the field definitions.

[m.chavet7MJRB]

Hello,

Thank you!

But with the "if records.Count>0", I will be not allowed to launch successvely my function in C3D, it will never work, because I get this error, this problem of records empties in all cases

[m.chavet7MJRB]

If there are no others solutions, I will create a function that create an excel file with all the values of each field for each alignement, instead of directly with the OD, somewhere in the pc root. Then, my others functions that manage with  all the profiles will find the required values there. Because it what I need, and it seems I'm not allowed to call these records two times, nobody has the answer...

[fieldguy]

You should post your entire solution - there is no reason for " Because it what I need, and it seems I'm not allowed to call these records two times".  My code will call your data as many times as necessary.
