Add A Reference So That Oracle Database Can Connect To Program
Apr 25, 2011
Well for some reason when i try to add a reference so that the oracle database can connect to the VB.NET 2010 program.In other words it shouldn't highlight certain code as if the database is not connected.Here is a clear summery as best as i can say what the problem is.
1. Connection from Visual Studio 2010 to Oracle plus server
2. Adding References will not be allowed for some reason.
3. The code (See example below on what it might be) is still highlighted even when i added the references several times.
I'll show just a small snip of the code coz it's more or less the same on most of the forms if i want to either update, delete, add or amend to the database. I'll show a few screenshots so to be clearer.I've tried by even looking over the notes and followed step by step and nothing works.Since i am not registered in this module this time i can't seek help of the lecturer so don't bother telling me to go and ask my teacher I've pestered the supervisor that i'd have to present this project to and she hasn't replied to my email at all so i have no clue what else to do in the matter.

I have some deprecated code in visual basic when connecting to an oracle database. I am using a OracleDataAdapter but it says that this has been deprecated. Does anyone know what the new supported code is to connect to a database?

I have a vb.net application that will not connect to an oracle database on the PC that I publish the app too. It works fine under my pc both in design and when I publish it to myself. But it will not connect under the pc I publish it too. I do have oracle installed on the pc and have the connection setup exactly as I have on my own pc. I am sure it is a file path issue, or at least I believe it to be that.

I have two small VB.NET applications that connect to the same Oracle database. One uses the OLEDB provider, and the other uses Oracle's ODP.NET. Should I expect to see problems with the OLEDB provider, as it's less 'native' to Oracle?

Is it possible to use a JDBC connection in a VB.net application? I am unable to find any example code in order to connect to an Oracle Database using JDBC within .net without the need to use Oracles .net drivers (they seem to not work without the Oracle client being installed and thats a licence problem)

I have installed Oracle 10g in one of my office's computer. I want to keep this as database server.

OraConn.Provider = "OraOLEDB.Oracle"

i am trying to redistribute my app that uses Oracle 11g:
Imports Oracle.DataAccess.Client
The problem i am having is that it will not run on a machine that doesnt seem to have the correct drivers that its looking for. When i install ODAC 11.2 Release 3 (11.2.0.2.1) with Oracle Developer Tools for Visual Studio on the test VM it works just fine but thats a 230+mb file to download and install! Not to mention that if the user already has Oracle 10/11g on their machine that it may mess up their current connections/etc by installing that setup file.Is there another setup package that i can install that only has the Oracle Data Provider for .NET 2.0 11.2.0.2.0 or whatever its needing from that ODAC 11.2 Release 3 file.

I'm working on a program tthat will connect to a database and display some data. But everytime i press a button to connect my program to the database i keep getting this error message Cannot open database "Northwind" requested by the login. The login failed. Login failed for user 'Aron-PCAron'. Now the reason why i'm so stumped about this is because when i connect to SQL Server 2005 manually, the login works just fine! This is the connect string i've got running in my prgoram
