If you have Firefox on your computer you should know that right after a new update has been installed, a Firefox Updated tab will automatically pop-up giving you the famous message : “You have been updated to the latest version of Firefox”. This tabs usually comes only once, upon opening Firefox for the first time, right after an update. Anyway, it may happen that this tab keeps opening by itself each time you start Firefox, along with a default Google tab. Let’s see how we can solve this issue.

Usually,  this issue is due when the Preference file doesn’t work properly, preventing Firefox from changing it once you first  saw the Firefox Updated message.  Here are a couple of solutions for you:

1. Visit this page, directly available at Mozilla website and follow the steps to solve the issue.
2. Install Mozbackup in Firefox and backup all of your Bookmark, saved passwords etc. Just do not back up the General Settings since they contain the issue you are trying to solve.
3. Close Firefox
4. Now, on Windows click Start, click Run… type %APPDATA%\Mozilla\Firefox and hit Enter.
5. Rename profiles.ini to  profiles.ini.bak
6. Open Firefox which will recreate a brand new profiles.ini.
7. Restore your stuff by using Mozbackup again.
8. Done!

We made heavy use of the ASP.NET membership and profile system for Video.Show (a Silverlight 1.0 video community website system, available onCodePlex). In addition to storing basic profile information, we created a custom profile with some additional fields. It's a really easy way to add add some additional personalization to your site without having to add a bunch of tables to your database.

This is really simple if you're using a Website Project - you can just add additional properties to the profile section of your web.config, and a custom profile class is generated on the fly when you rebuild your application. That makes things ridiculously easy. First, we'd define the property in web.config:

<!-- In web.config -->
<profile >
  <properties>
    <add name="FavoritePasta" />
  </properties>
</profile>

Profile.FavoritePasta = "Pumpkin Ravioli";

<span id="user-favorite-pasta"><%= Profile.FavoritePasta %></span>

Not so fast, I'm using a Web Application Project

Yeah, here's the catch. If you're using the Web Application Project model, the custom build handling for the profile doesn't kick in, so those custom properties you've lovingly crafted in your web.config aren't going to be compiled into a custom profile class.

There's a Visual Studio 2005 add-in called WebProfile that reads your custom profile and creates a custom class for you. That's handy, but I passed on it. For one thing, I haven't heard that there's a VS 2008 version of this. Additionally, I don't like to require a custom add-in in order to get my code to work in case I want to add a new profile property - especially when I'm working on a project that's going to be distributed on CodePlex.

Fortunately, it's not very hard to implement a custom profile. First, we'll write a class that inherits from System.Web.Profile.ProfileBase. I added a few static accessors, too:

using System.Web.Profile;
using System.Web.Security;

namespace VideoShow
{
    public class UserProfile : ProfileBase
    {
        public static UserProfile GetUserProfile(string username)
        {
            return Create(username) as UserProfile;
        }
        public static UserProfile GetUserProfile()
        {
            return Create(Membership.GetUser().UserName) as UserProfile;
        }

        [SettingsAllowAnonymous(false)]
        public string Description
        {
            get { return base["Description"] as string; }
            set { base["Description"] = value; }
        }

        [SettingsAllowAnonymous(false)]
        public string Location
        {
            get { return base["Location"] as string; }
            set { base["Location"] = value; }
        }

        [SettingsAllowAnonymous(false)]
        public string FavoriteMovie
        {
            get { return base["FavoriteMovie"] as string; }
            set { base["FavoriteMovie"] = value; }
        }
    }
}

<profile inherits="VideoShow.UserProfile">
  <providers>
    <clear />
    <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider"

	connectionStringName="VideoShowConnectionString"/>
  </providers>
</profile>

//Write to a user profile from a textbox value
UserProfile profile = UserProfile.GetUserProfile(currentUser.UserName);
profile.FavoriteMovie = FavoriteMovie.Text;
profile.Save();

Part of the reason for the accessor is to allow display of profile information for users other than the current user - for instance, a public profile page which displays information about other users in the system.

//Write to a user profile from a textbox value
UserProfile profile = UserProfile.GetUserProfile(displayUser.UserName);
Response.Write(profile.FavoriteMovie)

And of course, I can still databind to it as well:

<span id="user-favorite-movie"><%= VideoShow.UserProfile.GetUserProfile().FavoriteMovie %></span>

A few disclaimers:

• This isn't news, it's been out since ASP.NET 2.0 shipped. Still, it's pretty handy to know about, and if you're like me you may have forgotten or never really dug into some of the ASP.NET 2.0 goodies.
• This isn't the ultimate solution in terms of entity modeling. Custom profile information is stored in two columns in the aspnet_Profile table (delimited strings in one column, another column for binary serialized objects). That means that the only real way to read or write custom property values is via the profile API. That's not a real problem unless you need to query or join on information stored in a custom profile setting.

This is my first time posting an IT solution. Hopefully someone will google this and find it helpful. It's really a simple solution but I wished someone posted this and save me 2 days of headache. For a while I had a dillema on how to show ad on a 100% ajax web site. It's totally unfair to show only 1 impression of ads while the user is browsing your site. Currently, I'm using Google's Adsense and they don't give any help on Ajax Web thus I had to come w/ my own solution. Of course there was some help on the web to do this but it was a combination of results + my own solution that made it work.

Ok~ so let see what is fair use of this adsense. In my opinion (yours may differ..even Google), if there's a content change in your web site then it's fair to show a new ads on your page. Since I'm using AJAX, the best place to refresh the ad would be where you're making your HTTP request to the server. Example!

var oXmlHttp = createXMLHttp();

oXmlHttp.onreadystatechange = function() { 
     if (oXmlHttp.readyState == 4) {
          var storyDiv = document.getElementById(layerName); 
          storyDiv.innerHTML = oXmlHttp.responseText; 

           refreshAd(); 
      }
};

refreshAd() will refreash the ad. No better place then here. Do not put this under any onClick/onChange/onAnything behavior as it will only complicate your page like onClick="doSomething();refreshAd();" 

// Need to pass unique URI each time to make sure that your browser does not cache the result! This is needed for Firefox specifically!
function refreshAd() {
      var currentTime = new Date(); 
      googlead.location = "pages/ad.jsp?s=" + currentTime.getTime(); 
}

That's right! I'm using IFRAME.. I can already see you're not surprised as if you already know the solution. There's really no other option since any other solutions will be breaking Google's TOS. 
<iframe id="googlead" name="googlead" href="" src="" width="100%" height="100" scrolling="no" frameborder="0" marginwidth="0" marginheight="0"/> 

Create a globally access IFRAME named "googlead" or whatever you desired. To make sure that this page does not get cache, always pass a unique parameter. In this case I used client's system time. You could use other algorithm to create unique random characters but for lazy people like me will use what I did.

Great! I got my IFRAME to refresh on every HTTP/AJAX request.. but what the hell! it only shows Public Service Ad. I want to show ads that's related to my site!
Now in order for Google to content search your page... the content has to be inside wherever you put your google adsense script. For now this is what I had.

--ad.jsp-- 
<script type="text/javascript">
<!-- 
google_ad_client = "googleID";
google_ad_width = 728; 
google_ad_height = 90; 
google_ad_format = "728x90_as"; 
google_ad_type = "text"; 
google_ad_channel =""; //-->
</script> 
<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script> 

No wonder I'm getting PSA, there's no content!! now if I put a content then it shows litterally on your page.. which becomes stupid. Showing Ad and showing key word contents to the user will quickly condemn your site to hell. Now how can I put the content that's not visible to the audience? By pure stupid dumb luck, I found out that you can write invisible contents in your IFRAME by setting absolute height (that's right it took 2 days..my other solutions were too complicated and all failed).
<iframe id="googlead" name="googlead" href="" src="" width="100%" height="100" scrolling="no" frameborder="0" marginwidth="0" marginheight="0"/> 
For my ad I only need height of 100, so if I write anything below then it's invisible to the user and visible to the google content search engine! beautiful!! I just love dumb simple solution!

Ok~ now I put
<script type="text/javascript">
<!-- 
google_ad_client = "googleID";
google_ad_width = 728; 
google_ad_height = 90; 
google_ad_format = "728x90_as"; 
google_ad_type = "text"; 
google_ad_channel =""; //-->
</script> 
<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script> 
<br/><br/><br/><br/> 
<% if (yourKeyWord != null) { 
           print your key words here!
      } else { 
          print your general key words in case you don't have any. Example "Vacation Money Dating" better than PSA's!      
} %> 

Voila! Now I have total control of the content key words for google engine! In this case I used JSP where I save the content in my session and display on this page. But, I'm sure this techinque will work on whatever programming language.

Window.onload() is a workhorse of traditional javascript code. It’s been used by coders for years to kick start the client side magic as soon as everything on the page loads up.

But sometimes waiting for a page to load just isn’t quick enough.

A few large image files will quickly reveal that window.onload() can be painfully slow. So when I was creating a web app for internet marketers recently, I had to have something faster.

Some quick research into possible workarounds for the window.onload() issue brought me to some code by Brother Cake. If all you need is a fast way to kick start your javascript then their code might be something to try.

But if you’re going to be doing some DOM (Document Object Model) javascript coding then why not use jQuery and have your cake and eat it too (horrible pun - sorry).

jQuery has a handy little function that launches your javascript as soon as the Document Object Model is ready… which happens before the page has finished loading.

$(document).ready(function(){
  // Your code here...
});

You can use it to launch any kind of javascript you like. It doesn’t have to be reserved for jQuery style coding. And there’s nothing wrong with telling jQuery to launch several different functions at once.

Similar to many init() functions you may have seen before… just a lot faster.

You’ll see this code used again and again in the examples I give you on 15 Days of jQuery.
