Hi esperts,

  I had been trying many differents ways with this:

        I have Visual Studio 2003,2005 And 2008.
        I work at Visual Basic, In the company they have a Remote server with Oracle 8i.
        I have downloaded and installed Oracle for .Net providers 9,10g and 11g without any solutions.

       What i need is nomatter how is to connect Visual Studio to open a databse throu an SQL query in oracle to obtain a recordset in a datareader or to execute a SQL without any return.

     Any help or onyone experienced on this issue.

    The points will be assigned once the conneciton is made.
Thanks in advance for your help
 

Something like this:
 
        Dim oradb As String = "Data Source=Server IP ;User Id=MyId;Password=MyPassword;"
        Dim con As New Oracle.DataAccess.Client.OracleConnection
        con.ConnectionString = oradb
        con.Open()
