BLOB & MySQL problem

[nhunter98]

I am recieving an error when I am trying to write a blob file to MySQL. Can anyone help me figure out what I am doing wrong.

Here is my code:

Dim ScreenFileSize As UInt32 = 0
            Dim ScreenFile() As Byte
            Dim ScreenStream As FileStream

            ScreenStream = New FileStream(ScreenImageLocation, FileMode.Open, FileAccess.Read)
            ScreenFileSize = ScreenStream.Length
            ScreenFile = New Byte(ScreenFileSize) {}
            ScreenStream.Read(ScreenFile, 0, ScreenFileSize)
            ScreenStream.Close()

            Try
                MySQLQuery = "UPDATE " & MySQLDatabase & ".btt (ScreenShot) VALUES(?FileUpload) WHERE Ticket='" & strTicketNo & "'"
                MySQLCommand = New MySql.Data.MySqlClient.MySqlCommand(MySQLQuery, MySQLConnection)

                MySQLConnection.Open()
                MySQLCommand.CommandText = MySQLQuery
                MySQLCommand.Prepare()
                MySQLCommand.Parameters.Clear()

                MySQLCommand.Parameters.Add("?FileUpload", ScreenFile) 

                MySQLCommand.ExecuteNonQuery()
                MySQLConnection.Close()

            Catch ex As Exception

            End Try
        End If

Here is the first part of the error I recieve:
MySql.Data.MySqlClient.MySqlException was caught
