Install AjaxControlToolkit for VS 2008

Install AjaxControlToolkit for VS 2008
I am crying to develop ASP.NET using VS 2008 because that have limited control.
after download ajaxcontrol from http://asp.net I am happy because i get control for development.
1. Download for framework 3.5 ajaxcontrol from http://asp.net
2. Extract this file to C:\Program Files\Microsoft ASP.NET Ajax Extention.
3. Open your Visual Studio 2008.
4. Add tab in your toolbox and give toolbox name "AJAX Toolkits".
5. Choose Item and browse to your folder.
example : "C:\Program Files\Microsoft ASP.NET Ajax Extention\SampleWebSite\Bin\AjaxControlToolkit.dll"
6. Now you can see new component in "AJAX Toolkits"

Now you can use new component for your web application like datepicker, cascading dropdwon and more.
dot forget use this tag in your code.

Example using Calender Extender:

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>

<ajaxToolkit:ToolkitScriptManager runat="Server" EnableScriptGlobalization="true" EnableScriptLocalization="true" ID="ScriptManager1" />

<asp:TextBox ID="TxtUntil" runat="server" MaxLength="10" Width="80px"></asp:TextBox>
<asp:ImageButton ID="ImgUntil" runat="server" ImageUrl="~/images/Calendar_scheduleHS.png" AlternateText="Click to show calendar" />
<ajaxToolkit:CalendarExtender ID="CalExUntil" Format="dd-MM-yyyy" runat="server" PopupButtonID="ImgUntil" TargetControlID="TxtUntil"> </ajaxToolkit:CalendarExtender>

Memilih bahasa pemograman di .NET

Banyak pertanyaan yang muncul ketika saya mau memulai dengan pemograman .NET.
Bahasa pemograman apaan yang akan dipakai VB.NET atau C# sudah gitu mau desktop
atau web base.

Pertimbangan yang saya ambil yaitu :
1. Saya memilih C# kenapa?, ya karena itu baru buat saya walaupun bahasanya mirip dengan PHP. Trus kenapa gak pake VB.NET? Udah terlalu lama saya menggunakan VB rasa pengen yang baru biar gak terlalu jenuh waktu programming.

2. Pilih deksctop atau web base nah kalau yang ini bukan pilihan tetapi saya akan pilih dua-duanya. Kenapa? Programmer itu pada dasarnya tidak dibatasi oleh dekstop atau web base application.
Dia harus bisa mengimplentasikan suatu bisnis logic sesuai kebutahan sekarang dan nanti.

3. Visual Studio .NET versi berapa yang diapakai? Saya sarankan versi 2008 karena disitu ada technologi baru yaitu LINQ.

Sekian saja mudah-mudahan yang lagi bingung memilih tambah bingung lagi.
