you need to read a VERY basic book on ASP.NET, because it's clear you have no idea what it is, or what it does. An ASP.NET application can only run on a web server that has ASP.NET. It gets to users via the web, that's what ASP.NET is for,

Hi im using VS2008 to upload and display images.
I have a control with an <asp:Image control in it... if i save the image to a file on the server and specify the ImageUrl of the control it works fine.
however i want to avoid writing the image to a file before displaying it.
first of all, can I use the <asp:Image control to display the output of a httphandler or do i need to use something like
<img alt=""httpHandler"" src=""../App_Code/ImageHandler.ashx?productid={0}"">
secondly, what if anything do i need to add to the web config? - under HttpHandlers if I add
<add verb="*" path="*" type="ImageHandler"/>
then the actual pages are not loaded - just the results of the http handler as soon as the page loads
(I guess this tells me the actual HttpHandler works as the image is displayed)
the control that wants to use the HttpHandler is in a 'Controls' directory, the HttpHandler is in the 'App_Code' directory
the ImageHandler.ashx file is:
<%@ WebHandler Language="C#" Class="ImageHandler" CodeBehind="ImageHandler.cs" %>
the ImageHandler.cs file is:
using System;
using System.Web;
using DataLinq;
using BLL = BusinesLogic;
public class ImageHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
int _productID;
if (context.Request.QueryString["productid"] != null)
{
_productID = Convert.ToInt32(context.Request.QueryString["productid"]);
}
else
{
throw new ArgumentException("No parameter specified");
}
Product product = BLL.ProductBLL.GetByID(_productID);
if (product != null)
{
context.Response.ContentType = "image/jpeg";
context.Response.BinaryWrite(product.Image.ToArray());
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
Thanks,
Chas

ok managed to get this working...
The HttpHandler ashx and cs files didnt need to be seperated and the ashx file needed to be in a different directory to App_Code
I put it in a new directory called HttpHandlers...
I couldnt figure out how to use the handler with an asp:Image control (if anyone has the answer to this that would be great) so i used the img control specifying the src (wrapped in a div specifying the innerHtml)
Cheers,
Chas

The typical way to do this, is to write a page that takes an id on the URL, and returns the bytes of the image from the db. Then your image source url will be something like myhandler.aspx?id=23

You can tell the width and height of the screen, as someone said, but there is no way you can enumerate monitors with js

I think you can try wtih the Table width. That may restrict your page width.

You can't use that in ASP.NET. ASP.NET is stateless and got a different architecture than the rich-client applications.

Define any web form, then you established connection with any provider after this create command for
accessing query and finaly define datareader class.
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.OleDb;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
OleDbConnection con = new OleDbConnection("Provider=Microsoft.Jet.OleDb.4.0;Data Source=c:/db1.mdb;");
con.Open();
OleDbCommand cmd = new OleDbCommand("select *from login", con);
OleDbDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
if (TextBox1.Text == dr.GetString(0))
if (TextBox2.Text == dr.GetString(1))
Response.Redirect("default2.aspx");
else
lbl.Text="check the username and password";
CheckBox1.Text = "check the username and password";
}
//con.Close();
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
}

Its means your connection string is not valid. Do you have the database on web server or any different system ? What your connectionString contains?

Hi,
I am having a requirement like 'Scheduling Jobs' in a ASP.Net web site. Each user can create 'N' number of projects & schedule each project to run in a particular interval (Daily/ Weekly/ Monthly/ etc). Similarly we have 'N' number of users.
Each user needs to Edit/ Delelte the scheduled jobs & View the status.
One of my colleague suggested the below. Does any one of you have used this open source framework?
http://quartznet.sourceforge.net/[^]
Can you please suggest on this?
