Hi, Here is a shorter code example since the last message I posted was
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.Odbc.OdbcException' occurred
in system.data.dll

Additional information: System error.

'Data Access VB App.exe': Loaded
'c:\windows\assembly\gac\microsoft.visualbasic\7.0 .5000.0__b03f5f7f11d50
a3a\microsoft.visualbasic.dll', No symbols loaded.

Unhandled Exception: System.Data.Odbc.OdbcException: ERROR [07002]

e) in C:\Documents and Settings\System Admin\My Documents\Visual Studio
Projects\Data Access VB App\Form1.vb:line 225

The majority of the code was generated by Visual Studio and based on the
error message it would seem that I have to add SQLBindParameter
statements, but I am not sure the syntax that I should be using. I am
new to VB.NET (coming from Java/J2EE) and haven't been able to come up
with a workable solution after pouring over the MSDN manuals. Here is
some of the generated code:

That's the long and short of it! Appreciate any help.
