SQL Parameter collection problem

[NOTSOSURE]

I have created a form that will upload an image to an sql server

the data stored in the database will be:

pictureTitle
PictureDescription
PictureOwner
pictureData

each time i try and insert the information into the database the following error occures


An unhandled exception of type 'System.IndexOutOfRangeException' occurred in system.data.dll

Additional information: An SqlParameter with ParameterName '@pictureTitle' is not contained by this SqlParameterCollection.


Here is my code.. can u notice the problem please help..

Imports System.IO
Imports System.Data.SqlClient


    Public FileName As String
    Public PictureTitle As String
    Public PictureDescription As String
    Public PictureOwner As String = System.Environment.UserName

Private Sub MenuItem2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem2.Click

        Dim opendialog As New OpenFileDialog


        opendialog.DefaultExt = "*.jpg"
        opendialog.Filter = "Picture files(*.jpg)|*.jpg|Picture files_ (*.jpeg)|*.jpeg|Picture files (*.gif)|*.gif "

        If (opendialog.ShowDialog() = DialogResult.OK) Then
            Me.PictureBox1.Image = New Bitmap(opendialog.FileName)

            FileName = opendialog.FileName

        End If

        PictureTitle = Path.GetFileName(opendialog.FileName)
        TextBox1.Text = PictureTitle

    End Sub


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        SqlConnection1.Open()

        Dim myCommand As New SqlCommand("Insert INTO Pictures(pictureTitle, pictureDescription, pictureOwner, pictureData) values(@pictureTitle, @pitureDescription, @pictureOwner, @pictureData)", SqlConnection1)

        'Read jpg into file stream, and from there into Byte array.
        Dim myFileStream As New FileStream(FileName, FileMode.Open, FileAccess.Read)

        Dim arrayOfBytes(myFileStream.Length) As [Byte]

        myFileStream.Read(arrayOfBytes, 0, arrayOfBytes.Length)

        myFileStream.Close()

        'Copy entered values into parameters
        myCommand.Parameters("@pictureTitle").Value = PictureTitle
        myCommand.Parameters("@pictureDescription").Value = PictureDescription
        myCommand.Parameters("@pictureOwner").Value = PictureOwner

        Dim myParameter As New SqlParameter("@pictureData", SqlDbType.VarBinary, arrayOfBytes.Length, ParameterDirection.Input, False, 0, 0, Nothing, DataRowVersion.Current, arrayOfBytes)
        myCommand.Parameters.Add(myParameter)

        'Create variable for returned value from SQL execution
        Dim SQLreturn As Integer

        'Protect against problems using a Try...Catch block
        Try
            'Execute the command
            SQLreturn = myCommand.ExecuteNonQuery()

        Catch ex As Exception
            MessageBox.Show(ex.Message)

        End Try

        'Report back results
        If SQLreturn <> 1 Then
            MessageBox.Show("Could not execute the INSERT query")
        Else
            MessageBox.Show("INSERT completed successfully")
        End If

        SqlConnection1.Close()

i added the wrong veriable to the @pictureData Parameter it should be arrayOfBytes not pictureData

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click


        'Read Picture into file stream, and from there into Byte array.
        Dim myFileStream As New FileStream(FileName, FileMode.Open, FileAccess.Read)

        Dim arrayOfBytes(myFileStream.Length) As Byte

        myFileStream.Read(arrayOfBytes, 0, arrayOfBytes.Length)

        myFileStream.Close()

        SqlConnection1.Open()

        'Copy entered values into parameters, converting data type where necessary
        SqlCommand1.Parameters("@pictureTitle").Value = PictureTitle
        SqlCommand1.Parameters("@pictureDescription").Value = PictureDescription
        SqlCommand1.Parameters("@pictureOwner").Value = PictureOwner
        SqlCommand1.Parameters("@pictureData").Value = arrayOfBytes
        

        'Create variable for returned value from SQL execution
        Dim SQLreturn As Integer

        'Protect against problems using a Try...Catch block
        Try
            'Execute the command
            SQLreturn = SqlCommand1.ExecuteNonQuery()

        Catch ex As Exception
            MessageBox.Show(ex.Message)

        End Try

        'Report back results
        If SQLreturn <> 1 Then
            MessageBox.Show("Could not execute the INSERT query")
        Else
            MessageBox.Show("INSERT completed successfully")
        End If

        SqlConnection1.Close()

    End Sub
