Problem getting contacts from Exchange

When I attempt to use ADO to get data from any "Contacts" folder I always get...

System.AccessViolationException was unhandled

connection.Open();

OleDbCommand command = new OleDbCommand("Select * from [Staff]",connection);

using (OleDbDataReader dataReader = command.ExecuteReader(CommandBehavior.CloseConnection)) // EXCEPTION HERE

{

while (dataReader.Read())

{

}

}

I've tried the same code against my local stores and I get the same result. However, it works fine for every other folder type, Tasks, notes, inbox, etc. Any ideas?

Problem creating folder through package

hi !

I am creating a directory folder inside the package. At first attempt while running the package it creates without any errors but when i run it second time it throws up warning message : Directory already exists. but the package succeeds.

When i try running it from another server through command line it fails. saying that Device it not Ready.

What is the proble here !!!!!!! Any help please

Jas

Guess you should be getting some error like the following - "Error: 0xC002F304 at File System Task, File System Task: An error occurred with the following error message: "The device is not ready."

Please check whether the drive and the path to the folder which you are trying to create exist in the Server.

Thanks,
Loonysan

yes it does!!!!!

When i tried duplicating this problem from my machine accecssing a drive which was not there i got the same error SO i could understand that the drive and path should be correct to create the directory. When i tried the correct drive and path it work.

what are the methods to find what else the probelm could be? Permissions etc.

Thanks,

Jasmine
