I have tried everything I can to get beyond this error which shows below as <<<<< error here. It is trying to fill a dataset from a data adapter. If I change the SELECT statement to just SELECT * FROM xTable I get the correct number of records in each table. But anytime I try with a more complex statement I get the error message shown below which indicates System.Data.Common.DbDataAdapter.Fill(DataSet dataSet. I've completely erased all data and entered a new set of test data so I know there is no problem with relationships. Each table has primary key which is foreign key in other table. IS there something wrong with the Imports section: Imports System

I have a web site that I developed on Vista using Vb.net9. It makes a connection to Oracle. for the connection I use System.Data.OracleClient. It works fine on my machine, and our test server, but it does not work on the production server. We installed the Oracle Client 11 on the server. The error is System.Data.OracleClient requires Oracle client software version 8.1.7
We've tried, making a console app that opens the connection, connection runs fine, opens, displays a message and all is well there.Then we make a simple web form, put it in the directory of the program, just a button, opens the connection, try..catch, grabs error, same error.The console app was running under an Administrator, web site running under iwam. Is it possible that iwam has a different path?
I am using VS 2008 with frame work 2.0. On my development machine I am using Oracle 9 as database. When I deploy my application where Oracle 9 is installed it works properly. but it gives error on oracle8 NT installed machine as follow.
"System.Data.OracleClient requires Oracle client software version 8.1.7 or greater "I can get rid from this error.
i was under the impression that using the System.Data.OracleClient namespace will allow me to deploy my application without having the client machine install any OracleClient software besides the .Net Framework 2.0 which if i'm not mistaken, contains the System.Data.OracleClient.dll.
but after creating a WinForm application and then publishing it thru ClickOnce , i found myself getting this error when running the application on the client machine. is this a normal behavior or did i do something wrong in the process?
Converting from usind Micorsofts Syste.Data.OracleClient to what I believe is called Oracles ODT (Oracle.DataAccess 10.2.0.100). When I try and send a date I get this error "ORA-1858: a non-numeric character was found where a numeric was expected". This code worked great using System.Data.OracleClient.
cmd.Parameters.Add(New OracleParameter("I_FIRST_LOSS_EVENT_DATE", OracleDbType.Date)).Value = .LossEventsMessages(0).LossEventTime

I need to fill a datatable(in data set) row by row by providing the the data by variables in VB.Net. The variables assigns its value by loop.. so the datatable row should be filled row by row until the loop ends. There are three columns in the table. so the table should fill with different kind of datatype variables.

It appears that there is a 32K limit if I use a stored procedure. I read online that this does not apply if you are doing a direct insert, but I do not know how to create the insert string for a Byte Array. This is a thick client running on the server so not worried about SQL Injection attacks.

I am trying to perform a simple bound connection between an Access database and a text box on a form. This is actually Chapter 18 of the "Microsoft Visual Basic 2008" book.I get the same error message when trying to create my own project "MY ADO Form" or the "ADO Form" project supplied from the DVD provided with the book. I am running the 90 Day Trial Version of Visual Studio 2008 with SP1 and Net 3.5 SP1.
My operating system is the 64 bit Version of Vista with all updates.The error when I try to run the application in the debug mode is:"A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll"and as a result no data shows up in the text box from the database and the data selection bar is grayed out in the form. The underlying database "Students Data Set" appears to be fine as I have seen the correct data for the fields "Instructor" and "PhoneNumber" prior to running the program and when connecting with the database.
I need to pick all data in my application from my database and use it in my form
my question : how to pick all data in my application then i use it

It is a rather large table and takes a LONG time to load the form. I was thinking of loading the auto-generated "Fill" statement in a Backgroundworker, but it doesn't seem to be doing anything. I have the Fill statement in the DoWork event, but it never "finishes" it seems. My BindingNavigator stays at 0.
I looked at jmc's sig link and everywhere I look, it seems like I'm going to have to iterate one at a time, but how can I do this for a bound datasource?
