Hi, Here is a shorter code example since the last message I posted got
truncated. So the problem is I created a simple VB.NET 2003 application
through Visual Studio that connects to a MySQL database and loads a
table into a Dataset, and then displays that table information in a
DataGrid on a form for editing. The table fill works fine, the delete
function works fine, but when I try to update a row, the application
fails with the following error message:
An unhandled exception of type 'System.Data.Od bc.OdbcExceptio n' occurred
in system.data.dll
Additional information: System error.

The majority of the code was generated by Visual Studio and based on the

Hi Cor,
I had to install the MySQL ODBC driver to be able to access the MySQL
database, so that was why I opted to use ODBC. Thoughts?

Mikey,
I wrote this because ODBC gives sometimes trouble because there is not all
supported as with OleDb, SQLclient and OracleClient (The last two you
cannot use)
I have asked this to you it in a asking way because my expirience with MySQL
is nothing, however I would try in your situation OleDb. And when you have
trouble is, because it is MySql, certainly a better place to ask for help
for this the newsgroup

Hi Cor,
I will try the OLE DB approach and see if that makes a difference. I
will also post the question to the other newsgroups. Thanks for the
