            End With
            Try
                SQLConnection.Open()
                sqlCommand.ExecuteNonQuery()
                iReturn = True

            Catch ex As MySqlException
                MsgBox(ex.Message.ToString)
                iReturn = False
            Finally
                SQLConnection.Close()

您的SQL更新语法显示不正确。

更改：

.CommandText = "UPDATE user" & "SET FirstName = @FirstName" & "From user" & "WHERE Username = @Username;"

要

.CommandText = "UPDATE user SET FirstName = @FirstName WHERE Username = @Username;"

命令执行期间更新语句错误
