   1: public static string foo()

   2: {

   3: return foo;

   4: }

i use below ajax function below that works with almost all new mobile phones to create better user experience on my mobile sites.

function toggleBox(divId, DivState) // 1 visible, 0 hidden
{
var objToggle = document.layers ? document.layers[divId] : document.getElementById ? document.getElementById(divId).style : document.all[divId].style;
objToggle.display = document.layers ? (DivState ? "show" : "hide") : (DivState ? "block" : "none");
}
/************************************************************\

\************************************************************/
function ajaxRequest(mydiv, myloadingdiv, url)
{
var ajaxRequestObject = false;
try
{
ajaxRequestObject = new XMLHttpRequest();
}
catch(err1)
{
try
{
ajaxRequestObject = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(err2)
{
try
{
ajaxRequestObject = new ActiveXObject("Microsoft.XMLHTTP");
}
catch(err3)
{
document.getElementById(mydiv).innerHTML = 'No ajax support';
}
}
}
ajaxRequestObject.open('GET', url, true);
ajaxRequestObject.setRequestHeader('Content-Type', 'text/html');
ajaxRequestObject.onreadystatechange = function()
{
if(ajaxRequestObject.readyState == 4)
{
if(ajaxRequestObject.status==200)
{
toggleBox(myloadingdiv, 0);
document.getElementById(mydiv).innerHTML = ajaxRequestObject.responseText;
}
else
{
document.getElementById(mydiv).innerHTML = 'Could not retrieve data';
}
}
else
{
toggleBox(myloadingdiv, 1);

}
};

ajaxRequestObject.send();
}

you call the function like:

<a href="javascript:ajaxRequest('idofresultdiv','idofloadingindicatordiv','url.asp')">ajax</a>

For my new project i needed to protect actual location of files on my server and send them to visitor via download page/handler. Below code is a collection of sources found on the internet.

It is a class with 3 different methods. All does same job with a different approach.

using System;
using System.IO;
using System.Web;

public class Download
{


public static void SmallFile(string filename, string filepath, string contentType)
{
try
{
FileStream MyFileStream = new FileStream(filepath, FileMode.Open, FileAccess.Read, FileShare.Read);

byte[] Buffer = new byte[(int)FileSize];

HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(filename, System.Text.Encoding.UTF8));

Setup is very simple:

Open web.config file remove default domains and add your own domains . Rest of the settings pretty self explanatory such as allowed file types for upload and allowed file limit.

You need to setup wild card dns setup on your domain(s) in order to get sub domain system working.

You also need to setup a web site on iis without host headers if you will use more than one domain to serve sites. If you are using iis7 app needs to be on classic app pool due to limitation of URLRewriter

For caching rss feeds and flicker search results you need to have write access to apps root folder.

App uses 2 sql server databases, one is for content and user info the other is to host binary files. I have used sql server to store binary uploads for easy file management. It doesn't affect the performance as current setup gives only 5 mb space to each user.

I have provided full database script in /AppData/Db scripts folder. If you change name of PHNfileStore.mdf database make sure you alter trigger in users table of PHN.mdf . Trigger there deletes files of user when user removed from database

Once site up and running create to create your global admin account just register a user and set its isGlobalAdmin status to true from your sql database. This is required to manage global settings such as database cleanup,backup,setting up paid user status,checking/removing illegal sites

Please keep in mind that i am beginner to .net and there could be place for many improvements in the code
