I am trying to connect a simple VB program (Form, button and label) to my local oracle 10g XE and keep getting errors. The most recent errors is the TNS listener
"Oracle.DataAccess.Client.OracleException ORA-12154: TNS:could not resolve the connect identifier specified "
Here is what I have done:
Went to control panel > odbc and created a connection to 10g XE and called it:
oraconn (this was from other tutorial so it is not used in code but still resides)
Copied tutorial about connecting to oracle and have the following code:
Imports System.Data
Imports Oracle.DataAccess.Client
Imports Oracle.DataAccess.Types

View 1 RepliesI have installed Visual Studio 2010 and Oracle 11g in my Window 7. Oracle seem to be fine because i can connect to System user, Create user and create database. But the problem is that I can not connect the Oracle to my VB.net project and there is no System.Data.OracleClient Namespace. Do I need to install Oracle Client in my computer even though i have installed Oracle Server?

View 1 RepliesI've been viewing the tutorial at [URL]...08-088541.html but I'm still having issues creating my connection to our Oracle database. Here's my code, which uses the same connection string as one of my VB6 programs (no password required for database--Oracle picks up windows name) :
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Create connection object
Dim OraDB As String = "Data Source=databaseneme;Persist Security Info=False"
Dim conn As New OracleConnection(OraDB)
conn.ConnectionString = OraDB
conn.Open()
Me.Show()
End Sub
I've been using .NET for all of 10 mins so the error may be painfully obvious!
I am creating a Reporting program in VB 2008. The first issue that I want to correct is in VB 2008 there is a Database Explorer. But whenever I try to create a new Data Connection in the Database Explorer it does not give me the option to connect to Oracle. How do I get my Oracle Database in the Database Explorer tab. All it gives my options for are Microsoft based database applications.

I am reading a csv file in to a datatable in vb.net and making a few checks and appending an extra column. I then want to perform a bulk insert using microsofts Oracle.DataAccess (no choice in this) to an Oracle database. what would be the best way to perform this as there is no bulkImport like in SQLserver.

View 2 RepliesI have written a rather complex dll for processing a large volume of data (~4,000,000 records) from an Oracle database. It works well, but takes about 23 hours to run.Since I wrote the code fairly compartmentalized I realized that there are 6 routines that should be able to run concurrently, and I have a multi core processor,I decided to try my first multi-threaded implementation.
In the routine I am working on I am doing no I/O everything is in memory in variables. My data is already in dataTables and hashTables. Most of the data is defined as private in the class scope, but no conflicting updates should happen because the code segments works very distinct portions of the dataTables.The concept is simple, I have 2 routines that need to complete before launching my threads, and one routine that needs to run after all of the threads have completed. Here is what I am trying;
ProcessDXDate()
ProcessHistology()
aryThreads(0) = New Threading.Thread(AddressOf ProcessLaterality)[code].....
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.
Im writing a simple VB program that connects to an oracle DB which retreives and inserts data to a table I created.[code].....
I want to be able to search through a table I have created to store all the information.Rather than just searching for one variable which would be easy to do, I want to give the user the option to filter out the search from the form.So say the user hits "Find", they would be given access to 10 comboboxes, they would select the information they want to search for (They do not have to select every box) and then click "Do Find".Then the form would display all the results of the query in the form.

A VB.net program reads the queue and calls a stored proc in SQL Server that processes and then inserts the message into another SQL Server table and then deletes the record from the oracle table.
We use a DataReader to read the records from Oracle and then call the stored proc for each of the records. The program seems to be a little slow. The stored procedure itself isn't slow. The SP by itself when called in a loop can process about 2000 records in 20 seconds. But when called from the .Net program, the execution time is about 5 records per second.I have seen that most of the time consumed is in calling the stored procedure and waiting for it to return.[code]...
I am trying to open an Oracle database connection in vb.net 2008 in order to issue a Select statement and the populate a listbox with it.

Obviously, I am doing something wrong, but I can't figure out what.
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.
View 5 RepliesI've been trying to display some information from an Oracle Database(10G) in a VB.NET program. Some of this information is in french and I need to display the french accents correctly. The e with an accent chr(233) is my test case, and it keeps coming back as either an inverted question mark (with Ole DB), a question mark (with the System.Data.OracleClient) or an 'i' (with ODBC and DSN)..
