I'm trying to delete a bunch of records in mysql. The record info to delete (userid, name) is stored in an arraylist. It seems to only delete the first record and gives an error ("Transaction has already been rolled back or is not pending.") afterwards. I have the transaction commit inside the loop which I think is the issue but not sure how to go further if I bring it outside of the loop. Here's the relevant bits of the code.
try
{
ArrayList alist = new ArrayList();
//alist gets populated with data like (12345,robot)(23456,car) here.
MySqlConnection conn2 = new MySqlConnection(query_connection);
conn2.Open();
MySqlCommand command2 = conn2.CreateCommand();
MySqlTransaction mytransaction;
mytransaction = conn2.BeginTransaction();
command2.Transaction = mytransaction;
for (int i = 0; i < alist.Count; i++)
{
string[] s = alist[i].ToString().Split(',');
try
{
command2.CommandText = "DELETE from users_settings WHERE UserID=" + s[0].ToString();
command2.ExecuteNonQuery();
command2.CommandText = "DELETE from users WHERE ID=" + s[0].ToString();
command2.ExecuteNonQuery();
mytransaction.Commit();
}
catch (Exception e){
mytransaction.Rollback();
}
}
}
catch(Exception e){
}

Although the below connection string works for Select, Insert and Delete functions I can't get to work with Update.
Returns error 'unable to connect to MySQL hosts'
Sub Edit (sender As Object, e As EventArgs)
Dim myConnection As MySqlConnection[code]...

Im hosting my site over at some ISP, and when i try to use INSERT or UPDATE procedure, i get this error : "SELECT command denied to user 'KidumMac'@'localhost' for table 'proc' "Which is really wired for two reasons:
A. In my code i don't reference whatsoever to the MySql databse, nor the "proc" table
B. In the myPHPadmin program the queries work just fine. Any insights?
the second problem is that when i try to import my database, the tables import fine, but when it gets to import the stored procedure, it tells me that the user needs SUPER PRIVILEGES for that. what is it ?

Before I get too far down the road I just want some advice. I'm building a web app using VWD2008 and MySQL 5. I've got the membership provider stuff working fine and have an odbc connection setup which works "fine". what I've noticed is that when I configure a new sqldatasource (that will be used to provide data to a listview or something) the Advanced -> generate Insert,Update..... option is disabled. I'm assuming its because of the sql syntax difference of the square brackets issue between MS SQL Server and MySQL.
Before I start writing all my own insert and update statements does anyone know if there is a way to get MySQL and VWD to talk the same language, maybe a different connector or something. I'm using mysql-connector-odbc-3.51.15

I have used ASD.NET code using SQL Database for Transaction operation successfully. By changing the Database Code to interface with MYSQL an Error occurs. If I remove the Transaction Code from within the the application, it works OK by displaying the MYSQL data (Read Only) in the layout of the application. I am using Mysql Essential-4.1.22-win32 and MYSQL Connector ODBC-3.51.2. My objective is to EDIT the MYSQL Data.

//Create a connection to the database
MySqlConnection conn = new MySqlConnection("Database=kid07025;Data Source=195.178.228.254;User Id=kid07025;Password=********");

conn.Open();
//MySQL Query which updates the row where Anvandarnamn = Anvandarnamn (recieved from a cookie)

I don't know what I am doing wrong here, but the database doesn't get updated when I press the button.

I developed a web site more then a year ago with .net2.0/c#/mssql 2005. it works fine but i was asked to replace mssql with mysql.
I wrote a class to complete data access works (unfortunately, I didnt use nhibernate or other data access tools :((
I edited the class to use System.Data.Odbc objects rather than System.Data.SqlClient.
It works fine in selecting data but not manipulating data. when i try to insert new data it adds null data for all fields in the table.
in debug mode, i noticed that it might be caused by OdbcParameter but not sure.

I have been stuck on this for a while and I can't seem to get it to work despite looking for answers in books and all over the web, so I hope perhaps you all can help me figure this out...
Here's what I'm trying to do....
I have some information in a simple product database displaying in a gridview table. One of the columns is a row of checkboxes indicating whether the item has been discontinued or not. When the row gets updated, it needs to update the checkbox value in the database.
1. It needs to be disabled until the row is getting edited.
2. Send the string value of 0 or 1 to the database when the row is updated.
Here's the code for the sql datasource and the gridview part in question...
<asp:SqlDataSource ID="SqlDataSource1" runat="server"

I just moved to a new 2008 64 Bit Server. We are using MySQL, now also the 64 Bit version. Now I found out that there is a 64 Bit ODCB Driver, but not an 64 Bit Net/Connector.
Is that an issue or is the .NET Connector by default 32 and 64 Bit?

I did all the instructions which are in the following link: [URL] in order to do a connection between MySQL database and ASP.NET but I did not successed. Sometimes, it told me that I have a mistake in the <asp: button> and sometimes it told me that I did a mistake in calling (addImage) method. And this is my whole code:-
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="HW5._Default" %>
<script>
public class DataAccess
{
private string _strConn =
@"Driver= {MySQLODBC 3.51 Driver};SERVER=localhost;DATABASE=test1;";
private OdbcConnection _objConn;
public DataAccess()
{
this._objConn = new OdbcConnection(this._strConn);
}
// This function adds the Images to database
public string addImage(timestamp id, byte [] data,string extension)
{
string strSql = "SELECT * FROM File";
DataSet ds = new DataSet("Image");
OdbcDataAdapter tempAP = new OdbcDataAdapter(strSql,this._objConn);
OdbcCommandBuilder objCommand = new OdbcCommandBuilder(tempAP);
tempAP.Fill(ds,"Table");
try
{
this._objConn.Open();
DataRow objNewRow = ds.Tables["Table"].NewRow();
objNewRow["Extension"] = extension;
objNewRow["Data"] = buffer;
objNewRow["ID"] = id;
ds.Tables["Table"].Rows.Add(objNewRow);
// trying to update the table to add the image
