I am trying to connect to Oracle in a 32-bit Console Application. I am getting the following erorr. The code (with the exception of host, username, and password change) is below. It is a simple two function project.
Any help will be appreciated.
I am using C# in Visual Studion 2010 Premium and Oracle 10g. I can connect to the database with Oracle SQL Developer with the information set in the connection string.
