Newbie: Problems updating data from VB.NET

[Guillermo Najar]

Hi,

I'm beginner on VS2005 and MySQL; I have previous experience in PostgreSQL and Delphi 6.
I began developing some stuff using ASP.NET, VB.NET and SQL Server 2005 Express. I see that components like SQLDataSource (ASP.NET), DataSets, TableAdapters work perfectly under MS SQL; yet trying to use MySQL with MySQLConnector 5.1.1 there are some work arounds that I had to do to make it work with ASP.NET. Now I had to develop a quick and short app using VB.NET, and I'm facing more problems. One of my sure errors was to download MySQLConnector and not reading properly the documentation; when I saw I could connect to the MySQL database, I just started to work thinking I would get the same functionality as with SQL Server for components like DataSet, TableAdapter, BindingSource. I saw that SQL Commands for delete and update where not generated and I typed them in with "?" parameters. Yet I have not been able to update any single record. Trying to insert or update, the database is not updated, and I get no error messages. Trying to delete records I get an error: "concurrency error: delete command affected 0 of 1 expected records". Is there anything I missed to have it working? Its just a small app with 2 tables and basic insert/delete/update commands. In SQL Server 2005 works fine. I choose MySQL for being a popular open source DB, to offer my clients not to pay expensive MS licenses.

I have read some posts here regarding fixed problems on related issues like TableAdapter commands in DataSet generation (http://forums.mysql.com/read.php?38,149000,160639#msg-160639), indicating that in 5.1 GA would be fixed. What GA stands for? If I have 5.1.1, are these problems would be supposed to be fixed?

Thank you,
Guillermo
