HTTP handlers problems

I'm a newbie when it comes to HTTP handlers and i'm struggling to work out what the problemis with my current code

I seem to be getting this error

Class 'Handler' must implement 'Sub ProcessRequest(context As HttpContext)' for interface 'System.Web.IHttpHandler'.

When using this code

    <%@ WebHandler Language="VB" Class="Handler" %>

Imports System
Imports System.Web
Imports System.Configuration
Imports System.Data.SqlClient

Public Class Handler

    Implements IHttpHandler

Public Sub ProcessRequest(ByVal context As HttpContext)
Dim connStr As String = ConfigurationManager.ConnectionStrings("myConnectionString").ConnectionString
Dim con As New SqlConnection(connStr)

        ' Create SQL Command 

        Dim cmd As New SqlCommand()
        cmd.CommandText = "Select * from My_Images" +
                          " where id =@id"
        cmd.CommandType = System.Data.CommandType.Text
        cmd.Connection = con

        Dim ImageID As New SqlParameter("@investor", System.Data.SqlDbType.Int)
        ImageID.Value = context.Request.QueryString("id")
        cmd.Parameters.Add(ImageID)
        con.Open()
        Dim dReader As SqlDataReader = cmd.ExecuteReader()
        dReader.Read()
 开发者_如何学运维       context.Response.BinaryWrite(DirectCast(dReader("Image"), Byte()))
        dReader.Close()
        con.Close()
    End Sub
    Public ReadOnly Property IsReusable As Boolean _
        Implements IHttpHandler.IsReusable

            Get
                Return True
            End Get
        End Property

End Class

Has anyone got any ideas?

Thanks in advance

The method declaration

Public Sub ProcessRequest(ByVal context As HttpContext)

should be

Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

your method declaration is wrong. This should do it:

Public Sub ProcessRequest(context As HttpContext) 

MSDN link: http://msdn.microsoft.com/de-de/library/system.web.ihttphandler.isreusable.aspx

Cheers :)

Try:

Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

You will also need implements on the IsReusable property.
