    While trying to open the connection from VB.NET2008 application, system throws an error message like ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.

    By using toad application, I am able to access the DB.

    Can any please guide me to solve this issue

    For VB use same connection string & TNSNAMES.ORA data as TOAD uses.
    Oracle & listener work, as proven by TOAD; so fix VB's problem
    You can lead some folks to knowledge, but you can not make them think.
    The average person thinks he's above average!
    For most folks, they don't know, what they don't know.
    Good judgement comes from experience. Experience comes from bad judgement.
