Topic: LispFunction and signaling an error

Glenn;

Are you doing a library functions to be use from AutoLisp?

[Glenn R]

Luis,

Of course.

Cheers,
Glenn.

Cool,
I think I’m going try the ‘(nil . exception.message) for a while and
see how it works. Here is a sample output

Command: (ADO:Tools "C:\\NewMDB.mdb" "CREATE DATABASE")
(nil . "Database already exists.")

Command: (ADO:Tools "C:\\NewMDB.mdb" "CREATE TABLE Table1 (Name VARCHAR,
Address VARCHAR, Num INTEGE)")
(nil . "Syntax error in field definition.")

Command: (ADO:Tools "C:\\NewMDB.mdb" "CREATE TABLE Table1 (Name VARCHAR,
Address VARCHAR, Num INTEGER)")
(nil . "Table 'Table1' already exists.")

Code: [Select]

catch (System.Exception ex)
      {
        result.Add(new TypedValue((int)LispDataType.Nil));
        result.Add(new TypedValue((int)LispDataType.DottedPair));
        result.Add(new TypedValue((int)LispDataType.Text,ex.Message));
      }
      return result;

Daniel, with the apparent inability to use the 'out' keyword methodology, that seems to be an acceptable way to handle it.
Thanks for the conversation guys ... I'm looking forward to making time to play again.

Sorry to resurrect something so long dead, but have there been any new discoveries in this field?

[Glenn R]

Not by me Chuck...I gave up in disgust. Someone else might though.
Do you have something to share?

[Chuck Gabriel]

Do you have something to share?

Sorry, but no.  I'm just dipping my toes in for the first time and immediately ran into this problem.  If I do come up with something, I'll certainly share it, though.

The water's fine...jump in!
