    I need to store a array() of byte to a mysql field. I created a field in
    mysql of type varbinary. But storing and retrieving gives problems.

    Please help.

    strTemp = EnDeCrypt(txt, psw)

    Label1.Text = strTemp

    encData = System.Text.Encoding.UTF8.GetBytes(strTemp)

    Dim myconnstring As String = "host=vmge1; "

    Dim conn As New MySql.Data.MySqlClient.MySqlConnection

    Dim cmd As New MySql.Data.MySqlClient.MySqlCommand

    Dim myDataReader As

    Dim oParameter As New MySql.Data.MySqlClient.MySqlParameter

    conn.ConnectionString = myconnstring

    Dim strQuery As String = "UPDATE klanten SET secret=?ArrayParameter"



    cmd.Connection = conn

    cmd.CommandType = CommandType.Text

    cmd.CommandText = strQuery

    oParameter.ParameterName = "?ArrayParameter"

    oParameter.DbType = DbType.Binary

    oParameter.Value = strTemp

    Label1.Text = strTemp



    Catch ex As MySql.Data.MySqlClient.MySqlException

    Label1.Text = "Error " & ex.Number & " " & ex.Message

    End Try

    Dim strQuery2 As String = "SELECT secret from klanten"

    cmd.CommandText = strQuery2

    myDataReader = cmd.ExecuteReader()

    If myDataReader.Read Then

    Dim T As String = myDataReader.GetString(0)

    Label2.Text = T

    End If

    If Label1.Text = Label2.Text Then Label3.Text = "GELIJK" Else Label3.Text =
