Exception on command db.database.saveas(filename,dwgcurrent.curent)

[Anonymous]

my code :

...

InfoFichier = New FileInfo(Txt)
 'enregistrement
dwg.Database.SaveAs(Txt, DwgVersion.Current)

'vérification si fichier existe bien !
If InfoFichier.Exists = True Then
    dwg.CloseAndDiscard()

   ....

i have buid with framework 3.5.

This code work fine with Autocad v2010 but i have a exception with Autocad v2009. (same .dll)

exception DwgVersion.current

I have try another DwgVersion.AC1014 and other  but it  crash always on the SaveAS.

Can you explain this  ?

Thx

PS : I need to have the same .DLL. (At work, i have computers on Autocad 2009 and v2010). And i dont know how to programm ths VS project for multi buid.)
