Additional info:
Fixed in 1.0.8 by properly supporting new unsigned MySqlDbType enum values.
Description: the MySQLCommandBuilder Object always sets SByte für Byte, Int32 for UInt32 (and so on) in the MySQLParameter.DbType and the IsUnsigned flag always is False; so if e.g. in a Byte column a value > 127 should be set, .NET crashes with an OverFlowException How to repeat: - create a table with unsigned Column(s) (e.g. 'size') - create code: Sub test Dim da As New MySqlDataAdapter("SELECT size FROM test",conn) Dim cb As New MySqlCommandBuilder(da) Dim dt As New DataTable da.Fill(dt) Dim dv As New DataView(dt) Dim row as DataRowView row=dv.AddNew row("size")=120 row.EndEdit da.Update(dv.Table) '<= works, because value < 127 row=dv.AddNew row("size")=135 row.EndEdit da.Update(dv.Table) '<= crashes with System.OverflowException End Sub Suggested fix: Set IsUnsigned and DbType Properties correctly.
