I'm having some really annoying issue using ADO.NET connector.
I've added reference to my project- the file "MySQL.data.dll"
Actually, i've copied the file from "MySQL Connector Net 6.2.2Assemblies" to "MyWebSitein" and then added reference.
Then, typed "using MySQL.data" and as you can guess, i've got that message:
Namespace or type specified in the Imports 'MySql.Data.MySqlClient' cannot be found.
so i have a content page that load some content into repeater one of the repeater items is UserControl, when the page is load for the first time everything is perfect, but if i try to do postback and reload the repeater i get this error:
Code:
Exception Details: MySql.Data.MySqlClient.MySqlException: Invalid attempt to Read when reader is closed.
this error is raised in the repeater databind event.
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.

View 3 RepliesI 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 know that this sounds like a simple referencing problem from the title this is becoming a nightmare!I have a code class that uses the "iAnywhere.Data.AsaClient.dll". This Dll is referenced in the project and in the code class I have added this dll in the Using section.Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0246: The type or namespace name 'iAnywhere' could not be found (are you missing a using directive or an assembly reference?)The line that the Error points to this line in the class:using iAnywhere.Data.AsaClient;I have set the dll to copy local and it makes no difference, the Dll is installed on my PC so is in the GAC, I use this Dll with many other C# projects and have no problems.I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem.

I get this error message when I connect to the data source on localhostERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specifiedthe connection string is
connectionString="Data Source=DRIVER={MySQL ODBC 3.51 Driver};SERVER=localhost;PORT=3306; DATABASE=database;UID=xxx;PWD=xxx;OPTION=3;pooling=false;"
providerName="System.Data.SqlClient"
it must be some kind of problem in the environment since the connection string works on a remote server. I downloaded the driver and added it with the Data source (ODBC) application in the control panel.
