How to save binary data to SQL-Server using VB.NET

I'm having following problem: In my SQL-Server DB I have a table that has only one column "BytesPassWord" of type varbinary(24). Now, in my VB.NET app (WinForm) I'll create an array of type Byte,  bytPassWord() as Byte with 24 bytes in the array,
after creating the array I'll fill it with some byte values.

How I can save this binary data into my table in SQL-Server ??

Here ya go:

<form runat="server" enctype="multipart/form-data" ID="Form2">
  <P>
    <input type="file" id="file1" runat="server" NAME="file1">
  </P>
  <P>
    <asp:Button id="btn1" runat="server" text="Upload" onclick="upload" />
  </P>
</form>

--------------------------------------------------------------------------------------

Imports System.Data
Imports System.Data.SqlClient

Public Sub Upload(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim b(file1.PostedFile.InputStream.Length - 1) As Byte

        file1.PostedFile.InputStream.Read(b, 0, file1.PostedFile.InputStream.Length)

        Dim con As New SqlConnection(ConfigurationSettings.AppSettings("ConnectionStringSQL"))

        Dim sql As String = "INSERT INTO MY_TABLE(MyID, DATABLOB) VALUES(1,@BlobData) "
        Dim cmd As New SqlCommand(sql, con)

        Dim parmBlob As New SqlParameter("@BlobData", SqlDbType.Image, _
                     b.Length, ParameterDirection.Input, False, 0, _
                     0, Nothing, DataRowVersion.Current, b)
                     
        cmd.Parameters.Add(parmBlob)

        con.Open()
        cmd.ExecuteNonQuery()
        con.Close()
End Sub

Thats for ASP.NET/VB.NET obviously, but the vb should be the same for forms

you should really use SqlDbType.VarBinary instead of SqlDbType.Image in the sqlparameter thou, since you said it was a varbinary. Won't make much difference either way, just me being picky :)
