I'm loading information from DB into DataTable with the following code:

data = new DataTable();
if (connection.State != ConnectionState.Open) connection.Open();
da = new MySqlDataAdapter(query, connection);
cb = new MySqlCommandBuilder(da);
try
{
    da.Fill(data);
}
catch(Exception)
{
    return;
}

After doing an update

C#

da.Update(data);

adapter read only columns. This went fine until a Windows update (don't know wich). Do you know why?

I think you are missing the assigning the update command from the commandbuilder to the dataadapter.

C#

da.UpdateCommand = cb.GetUpdateCommand();

at least that is how I recall it needing to be done, you would think it would assign it automatically since your passing the dataadapter as a parameter, but if my memory serves me correctly you have to apply any of the commands you want from the commandbuilder.
