Google Chrome Review - My first impressions

Google Chrome is the latest web browser released by internet Search giant Google just a few days back with whom Google tried to bring the best of the existing browsers at a single place . You can download Google Chrome here.

The installation will be very smooth. Just Click the big blue button in the link above and you can download and install chrome in no time. It does migration just like as it used to happen with Firefox . It will import all your bookmarks, default search , your usernames and passwords... from IE and Firefox smoothly. Now you are ready to run the browser.

The browser loads pretty quickly compared to Firefox. But the amount of speed with which the page loads will be almost same as Firefox. The omnibar (Adress bar cum Search bar ) is what I like the most in Google Chrome ( I dont have to open Google everytime when I have to search).
There is no title bar in Google Chrome unlike IE and Firefox. And the home page in Google Chrome is a history of the pages you visited the most . This is pretty good feature for those who access some sites regularly and wants to access them in a click.

Most of the things like gears which we had to install separately earlier comes inbuilt with Chrome . The disadvantage for Chrome at this moment is that it don't offer extension capabilities unlike Firefox . I shifted to Firefox because of the Extensions and the tabbing feature both which are not offered by IE those days.Without them Chrome looks to me as a casual browser.

Chrome uses one process for each tab it opens . So even if a page crashes, only that page will closed not the browser.When you close a tab , the process of that tab is closed and the memory allocated is released. If you want to know more , you can check the Google Chrome Book .The DOM ( Document Object Model ) inspector in Chrome reminders me of Firebug through which you can inspect each and every element and, at the same time, traverse though the objects and see the styles aplied to each element. Just Right click on something in page and select ' inspect element ' and it shows CSS/HTML details. For achieving this we had to install Firebug Extension in Firefox.

The task Manager in Chrome is one more chilling feature.It displays plugins and each tab's network , CPU and Memory Usage.The inbuilt spell checker is also quite Helpful .Unlike Firefox where we have annoying popup for downloads , Downloads in Chrome happen in its taskbar with a cool animation in the start (A blue button pointing to the taskbar ).

Finally Chrome looks to me not so Special but as a effort by Google to unify the good features of the rest of browsers. I don't think many of the users might shift from Firefox and IE to chrome at this moment. May be if Google offers something extra ordinary , People might give it a try.

Required Entries in web.config file for ASP.NET AJAX applications to run properly.

Before you start this , I recommending you reading ‘ How to remove 'Sys' is undefined ? ’

Following are the required entries in your web.config file for the ASP.NET AJAX applications to work with out errors. If you are integrating AJAX in your ASP.NET 2.0 application , then only you need to check this .If you are creating from AJAX Enabled website template in Visual Studio , these will be added automatically .

1.CONFIG Sections : For registering the system.web.extensions namespace, assembly and the various handlers that are used in handling AJAX requests.

<configSections>

<sectionGroupname="system.web.extensions"
type="System.Web.Configuration.SystemWebExtensionsSectionGroup,
System.Web.Extensions, Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35">

allowDefinition="MachineToApplication"/>

<sectionGroupname="webServices"type=

"System.Web.Configuration.ScriptingWebServicesSectionGroup,
System.Web.Extensions, Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35">

<sectionname="jsonSerialization"type=

"System.Web.Configuration.ScriptingJsonSerializationSection,
System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"requirePermission="false"
allowDefinition="Everywhere"/>

<sectionname="profileService"type=

"System.Web.Configuration.ScriptingProfileServiceSection,
System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"requirePermission="false"
allowDefinition="MachineToApplication"/>

<sectionname="authenticationService"type=

System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"requirePermission="false"
allowDefinition="MachineToApplication"/>

</sectionGroup>

</sectionGroup>

</sectionGroup>

</configSections>

2. In your system.web Node , Make sure you have these entries so that we can register the " asp " tag prefix to AJAX Controls .

<pages>

<controls>

<addtagPrefix="asp"namespace="System.Web.UI"assembly=

"System.Web.Extensions, Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"/>

</controls>

</pages>

3. Now find <compilationdebug="false> and add the following.This enables compilation of your website by referring to the following assemblies.

<compilationdebug="true">

<assemblies>

<addassembly="System.Web.Extensions, Version=1.0.61025.0,
Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

<addassembly="System.Web.Extensions.Design,
Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=31BF3856AD364E35"/>

</assemblies>

</compilation>

4.Now to ensure that that your HTTP handler is registered and to specify that webservices might be handled by Async Callbacks (from JavaScript) Check for following lines or add them.

<httpHandlers>

<removeverb="*"path="*.asmx"/>

<addverb="*"path="*.asmx"validate="false"
type="System.Web.Script.Services.ScriptHandlerFactory,
System.Web.Extensions, Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"/>

<addverb="*"path="*_AppService.axd"validate="false"type=

"System.Web.Script.Services.ScriptHandlerFactory,
System.Web.Extensions, Version=1.0.61025.0,
Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

<addverb="GET,HEAD"path="ScriptResource.axd"type=

"System.Web.Handlers.ScriptResourceHandler,
System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"validate="false"/>

</httpHandlers>

<httpModules>

<addname="ScriptModule"type=

"System.Web.Handlers.ScriptModule, System.Web.Extensions,
Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"/>

</httpModules>

5.Now add the following after </system.web> tag.We add these lines to enable Json Serialisation or, authentication settings and some profile settings.Check for these lines or add them.

<system.web.extensions>

<scripting>

<webServices>

<!-- Uncomment this line to customize maxJsonLength
and add a custom converter -->

<!--

<jsonSerialization maxJsonLength="500">

<converters>

<add name="ConvertMe" type=
"Acme.SubAcme.ConvertMeTypeConverter"/>

</converters>

</jsonSerialization>

-->

<!-- Uncomment this line to enable the
authentication service. Include requireSSL="true" if appropriate. -->

<!--

<authenticationService enabled="true" requireSSL = "truefalse"/>

-->

<!-- Uncomment these lines to enable the profile service.
To allow profile properties to be retrieved and modified in
ASP.NET AJAX applications, you need to add each property
name to the readAccessProperties and

writeAccessProperties attributes. -->

<!-- <profileService enabled="true" readAccessProperties=
"propertyname1,propertyname2"

writeAccessProperties="propertyname1,propertyname2" />

-->

</webServices>

<!--

<scriptResourceHandler enableCompression="true" enableCaching="true" />

-->

</scripting>

</system.web.extensions>

6.Finally you have to register the script handler factory which will be done by the following lines.Check for them or add them to your web.config

<system.webServer>

<validationvalidateIntegratedModeConfiguration="false"/>

<modules>

<addname="ScriptModule"preCondition="integratedMode"
type="System.Web.Handlers.ScriptModule, System.Web.Extensions,
Version=1.0.61025.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"/>

</modules>

<handlers>

<removename="WebServiceHandlerFactory-Integrated"/>

<addname="ScriptHandlerFactory"verb="*"path="*.asmx"
preCondition="integratedMode"type=

"System.Web.Script.Services.ScriptHandlerFactory,
System.Web.Extensions, Version=1.0.61025.0,
Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

<addname="ScriptHandlerFactoryAppServices"verb="*"
path="*_AppService.axd"preCondition="integratedMode"
type="System.Web.Script.Services.ScriptHandlerFactory,

System.Web.Extensions, Version=1.0.61025.0,

How to remove 'Sys' is undefined ?

Many of my Co – developers who are trying to integrate ASP.NET AJAX into their applications are getting this error. Even newbies who start using ASP.NET AJAX run into this error. So before we start on How to remove ‘ Sys is undefined ‘ , let me throw a light on the possible outcomes which might result in this error ?

You might had observed the ASP.NET AJAX requires to have atleast one script manager on the page where you want to use it. The script manager will render various script tags from the AJAX libraries so as to initialize and run the AJAX scripts. If you try to view source code rendered by the browser , you will find something like this .

Sys.WebForms.PageRequestManager._initialize('ScriptManager1', document.getElementById('aspnetform'));
Sys.WebForms.PageRequestManager.getInstance()._updateControls(‘UpdatepanelControlsArray ’);

Note : Aspnetform, UpdatepanelControlsArray will be replaced by your page form ID and Update panelID’s separated by comma , you have on your page.

When the browser runs this code, it will expect Sys.WebForms.PageRequestManager to be defined somewhere already which happens to be in the AJAX library scripts that are loaded by the script manager.
If the browser fails to load those scripts, the script engine can’t find the definition for Sys, Sys.WebForms, Sys.WebFormsPageRequestManager, and returns the error ‘Sys’ is undefined .

Removing ‘ Sys ’ is undefined :

1.If the error is coming only in IE6 and not in other browsers ,There may be issue in compression of the scripts which will be handled by the Script resource handler. So make sure you have the latest version of AJAX Extensions and try turning off Compression in your web.config file as shown below .

<system.web.extensions>
<scripting>
<scriptResourceHandler enableCompression="false" enableCaching="true" />
</scripting>
</system.web.extensions>

2. Required Entries in web.config missing : Make sure your web.config contains the all the required entries for the AJAX to work. If you want to know required web.config entries for AJAX , Click here.

3. The virtual directory you are using for your web, may not be marked correctly as an application. Make sure you are using a web application and not just a IIS directory. In your IIS Manager right click on the virtual directory and click Convert to Application and you are done.

4. ScriptResource.axd requests return 404 :This happens as a result improper installation of ASP.NET. On a default installation of ASP.NET, any web request to a resource ending in .axd is passed from IIS to ASP.NET via an isapi mapping. Additionally the mapping is configured to not check if the file exists. If that mapping does not exist, or the check if file exists isn't disabled, then IIS will attempt to find the physical file ScriptResource.axd which if it is not able to find returns 404 error.

You can check to see if this is the problem by copy/pasting the full URL to ScriptResource.axd from the source which will be something like below and running it.

<script src="/YourWebApplication/ScriptResource.axd?[Some query string]" type="text/javascript"></script>

To fix this run "aspnet_regiis.exe" in Visual Studio command line tool to fix it up.You can run "aspnet_regiis -i -enable", which does the full registration of ASP.NET with IIS and makes sure the ISAPI is enabled in IIS6. You can also run "aspnet_regiis -s w3svc/1/root/ YourWebApplication " to fix registration of your web application.
