Hello,

I have the version 2.0 of framework.
And i have an error message on a developpment who work on 1.1 :

Exception Details: System.Data.OleDb.OleDbException: Erreur non spécifiée
Source Error:
Line 25: DataSet myDataSet = new DataSet("Entreprise");
Line 26:
Line 27: myDataAdapter.Fill(myDataSet,"Entreprises");


Here is my code :
string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +
(Server.MapPath("/data/planning.mdb"));
OleDbConnection conn = new OleDbConnection(connectionString);
OleDbDataAdapter myDataAdapter = new OleDbDataAdapter("Select * from
Entreprises",conn);
DataSet myDataSet = new DataSet("Entreprise");
myDataAdapter.Fill(myDataSet,"Entreprises");
....

This method still work on asp.net 2.0 ?
 
It would help to know what exception is thrown.

Yes it would help. But the message of the server is :
"Exception Details: System.Data.OleDb.OleDbException: Erreur non spécifiée"
Erreur non spécifiée = error no specify
 
Did you setup a try/catch exception handler to trap the exception display
the message?
