Hi,
I have this problem with http handler where i can't use the javascript on the page that the handler is associated with, for example the handler writes an image to an aspx page and i have a javascipt that disable the right click on that page when i run the page without the handler the javascript works but when i run it with the handler it stops working
Here are all the codes:
Handler Code:
First Page:
Page associated with handler html Code:
Web.config for handler:
I think that handler clears all of that page content because i tried to add some code to debug it but it didn't run in the debugger when i associated the page with the handler
Can anyone help me with it?
Thanks in adavance

Here are all the codes:
Handler Code:
VB.NET:
Imports Microsoft.VisualBasic
Imports System.Drawing
Public Class ImageHandler
Implements IHttpHandler
Public ReadOnly Property IsReusable As Boolean Implements System.Web.IHttpHandler.IsReusable
Get
Return False
End Get
End Property
Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest
Dim request As HttpRequest = context.Request
Dim id = request("id")
Dim path As String = "D:\" + id + ".jpg"
Dim i As Image = Image.FromFile(path)
context.Response.Write("hello")
context.Response.Clear()
context.Response.ContentType = "image/jpeg"
i.Save(context.Response.OutputStream, Imaging.ImageFormat.Jpeg)
End Sub
End ClassFirst Page:
VB.NET:
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Button1.Attributes.Add("onclick", "window.open('Image.aspx?id=08052010195','','toolbar=no,location=no')")
End Sub
End ClassPage associated with handler html Code:
VB.NET:
