Create a user login is often necessary in building a web application. Not as alleged, that user login is secure can be made easily. There are several techniques to create a user is logged, among others: * By using the hidden form. This is not flexible, because it requires each page to check the data sent by the form, so if users change the page without pressing the button to submit, will be considered invalid. * By using cookies. This is good enough, because it allows the user flexibility in moving the pages. But the cookies are valid for the browser has not been turned off, so less secure. Imagine if you leave your browser in the circumstances have not closed, then there are others who wear it. * By using the session. This will be discussed. IIS is packed with state management of the facilities is very good, through the concept and application session. To create a user login that this simple, yet still required the use of the global.asa in your ASP file. This application requires a 3...

ASP.NET AJAX is a framework for ASP.NET AJAX 2.0. By using ASP.NET AJAX, we can make web applications more responsive and interactive. To create a web application using the AJAX-enabled ASP.NET AJAX is very easy. Web programmer with limited ability Javascript can make web applications and interactive resonsif using ASP.NET AJAX. ASP.NET AJAX can be downloaded at http://ajax.asp.net . Some of the benefits of web applications using ASP.NET AJAX applications compared with a fully web-based servers, among other: * More efficient because the process is done in the browser. * UI element that is more familiar as indicators of the process, tooltips and pop-up window. * Update Many pages that change only part of a web page (partial rendering). * Integration with client ASP.NET application form for authentication services and user profiles. * Framework is easily tailored to the needs of the server-control. * Support the most popular browsers including Microsoft Internet Explorer, Mozilla Firefox...

You are now in a position to examine the formal structure of an ASP.NET page. The following is a list of the important elements of an ASP.NET page: * Directives * Code declaration blocks * ASP.NET controls * Code render blocks * Server-side comments * Server-side include directives * Literal text and HTML tags Each element is discussed in the following sections. Directives A directive controls how an ASP.NET page is compiled. The beginning of a directive is marked with the characters . A directive can appear anywhere within a page. By convention, however, a directive typically appears at the top of an ASP.NET page. There are several types of directives that you can add to an ASP.NET page. Two of the most useful types are page and import directives. Page Directives You can use a page directive to specify the default programming language for a page. Page directives can also be used to enable tracing and debugging for a page. To change the default programming l...

Windows Vista is released November 2006 appears to be immediately pan. Parties, the new generation replacement has been released in beta version. Windows 7, which was known by the name Blackcomb and Vienna is planned later in 2010 will be outstanding. Currently no certainty that the name will be taken this far because Windows 7, Windows Seven, Vienna, and Blackcomb is the codename Microsoft used for development. Like the Vista and XP, Windows 7 is also a version will be marketed in 32-bit and 64-bit. Although Microsoft has not released the statement about the features that are owned and pointing Windows 7 is, some observers predict that Windows 7 will include IE 8 and Windows Future Storage (WinFS) as one of its components. IE 8 beta 1 is integrated with Windows Server 2008, which yesterday released in February. Meanwhile, WinFS, which originally planned to strengthen the candidate to replace Vista NTFS file system must be delayed because it is still in the project. From some of the si...

ASP.NET : SOME BACKGROUND ON CONTROLS Web custom controls exhibit several advantages over user controls. User controls are not ideal for re-use, as their ASCX and class files must be copied into each project that consumes them. They are also handicapped by a lack of designer support in Visual Studio .NET. Drop one on a Web form and you'll see what I mean; they are represented by a generic, grey box, and the IDE offers no help in determining the control's properties. The main benefit of user controls is that they are very easy to create, and this promotes rapid application development. Web custom controls, on the other hand, can be quite appealing. There is no ASCX file for a Server Control, so they are very easy to re-use. You need only set a project reference to the DLL, and you're off to the races. Web custom controls can also be added to your VS .NET Toolbox for ultra-simple re-use. You can even install a Web custom control in the Global Assembly Cache, but a discussion ...

How to Creating a Slightly More Complex Control ? For this example, we will create a login screen that consists of two labels, two text-box server controls, two required field-validation server controls, and a button server control. We will also expose a property or two to make it a little more versatile. After we have created a blank user control in our project, add the following. In the code-behind, add the following code. The first thing to notice is that a user-control class is abstract. It must be inherited to implement its functionality. This is done by the parent page, which treats the user controls as a child object. Also, notice that the class inherits from System.Web.UI.UserControl. This gives the control the internal plumbing it needs to render itself. Most of the events and properties can be specified and overridden in your code-behind. After the control declarations, we declare two global variables. These contain the values set in the public property get and set routines....

How to Creating a Simple User Control ? Follow this capture : In this article, we will build two user controls. To cover the very basics, our first example will be an extremely simple calendar control. The control builds on the functionality of the existing ASP.NET calendar control by adding a text box to store the value selected. The calendar visibility will be toggled by a button. The user control could then be useful on a form that requires a date to be entered, but page real estate is a concern. For clarity, both examples are written in C#, and the full source code is available for download. To create our first user control, we need to add a user-control file to a project. First, create a new C# ASP.NET Web application. Right click on the project in the Project Explorer and click Add - Add New Item and select a Web User Control item. This adds a file with the extension .ascx to the project. This is the file that the user control will use to expose its interface. An .ASCX file cann...

User Controls vs. Other Controls in ASP.NET One source of confusion when working with ASP.NET is knowing the difference between the many different types of controls out there and what they should be called. Microsoft has attempted to distinguish this variety, but myriad names still exist for elements that have only subtle differences. For instance, an ASP.NET control (sometimes called a server control) is a server-side component that is shipped with .NET Framework. A server control is a compiled DLL file and cannot be edited. It can, however, be manipulated through its public properties at design-time or runtime. It is possible to build a custom server control (sometimes called a custom control or composite control). (We will build these in part 2 of this article.) In contrast, a user control will consist of previously built server controls (called constituent controls when used within a user control). It has an interface that can be completely edited and changed. It can be manipulat...

What Is an ASP.NET User CONTROL ? If you have been dabbling in ASP.NET for any time, you have probably heard myriad definitions for a "user control." Why not add one more to the list? An ASP.NET user control is a group of one or more server controls or static HTML elements that encapsulate a piece of functionality. A user control could simply be an extension of the functionality of an existing server control(s) (such as an image control that can be rotated or a calendar control that stores the date in a text box). Or, it could consist of several elements that work and interact together to get a job done (such as several controls grouped together that gather information about a user's previous work experience). ASP NET CONTROL In either case, a user control typically resides on a page with other elements. This breakup of functionality could be the basis of an entire application built with independent and reusable user controls. The controls could then be dynamically loaded...

Components of checking the Class Components In a program usually make it clear inputan form before the latest data on inputs. This is normally done to help the user distinguish between the input data with new data input koreks. When we use the components so TEdit we often use the command edit1.text :=''; means edit1 column blank value. sebgai example we will menginput student data before the new data submitted, we will clear the form input fields with the first. eNim.text:=''; eNama.text:=''; eAlamat.text:=''; and so forth. techniques such as this is not why, but sometimes make when we use saturated many tedit in a form inputan. so that the necessary rigor in order to provide one by one. There may be a function can overcome this problem. so we do not need to give commands on a component Tedit to clear the value. We undertake sufficient component of the class, if the component is Tedit then we fill with the value''or empty The following functions ...

HOW TO ADD SCROLLBAR IN LISTBOX In the default condition, ListBox not have horizontal scrollbar. If you want to add horizontal scrollbar in a ListBox component, can use the following procedure procedure SetHorizontalScrollBar(lb : TListBox) ; var j, MaxWidth: integer; begin MaxWidth := 0; for j := 0 to lb.Items.Count - 1 do if MaxWidth MaxWidth := lb.Canvas.TextWidth(lb.Items[j]) ; SendMessage(lb.Handle, LB_SETHORIZONTALEXTENT, MaxWidth + 5, 0) ; end; See ListBox

Array types defines the list of elements with a certain type. You can usually use the index in square brackets to access one of the elements array. Angle brackets are also used to determine the value of the index when possible to define arrays. For example, you can specify a group that consists of 24 integer with the code as follows type DayTemperatures = array [1..24] of Integer; In the array definition, you must spend a subrange type in square brackets, or define a subrange type that uses two new constant with Ordinal type. Subrange this will determine the array index is valid. Because you determine the value of the index up and down from the array, the index does not need to be based from the value 0, such as that required in C, C + +, Java, and other programming languages. Because the index is based on the array subrange, Delphi can check their range as we have seen before. A constant subrange invalid will generate an error during the compilation, and when we use an index that ex...

what the asp sintax ? If you have experience with PHP, Javascript, or ASP programming, the asp sintax almost the same with the other. However, if you only have experience with web technologies such as HTML and CSS, the ASP will be more of a challenge. How to use HTML tags to create a web page, ASP requires the tag to become a dynamic web site. This tag is used in a typical HTML tags, so make sure you see the difference between the tag and used for ASP tag that is used for HTML. Below is our ASP scripts used in previous studies. what the asp sintax ? Response.Write("Hello Me") %> These special tags will always encapsulate your ASP code. Some things about the ASP tag that sets it apart from normal HTML tags: 1. An opening ASP tag is 2. A closing ASP tag looks like %> while an HTML tag normally looks like 3. ASP code can occurr anywhere, even within an HTML tag opening tag like this: code asp: ">Home the explorer will display Home what the asp sintax ?

First ASP Script Before we learn more about programming ASP, we run the ASP script is very simple to check whether the installation of IIS and ASP, which is functioning properly. Open a text editor and write the following ASP code and save with the name "firstscript.asp." Be sure to save this file to the directory "tizagASP" as was mentioned in the previous lesson, Running ASP. Launch Internet Explorer and type the following into the address bar: Internet Explorer will Display: Hello Me ...then you've got all the file saving and running mumbo jumbo figured out and you can start focusing on learning ASP! Now let's continue! First ASP Script

If you do not know where to save the file and how asp files from your ASP pages, this lesson will guide you through the process to run asp the first time. After IIS is installed correctly, the next step is complete and you must save your ASP files in a special location on your hard drive: Inetpub directory that is specific. Follow these steps to navigate to this directory: 1. Open up "My Computer" or "Windows Explorer" so that you can view your system's files and directories. 2. Select and Open the C drive (C:) 3. Double click the Inetpub folder 4. Double click the wwwroot folder - The full path to this location is "C:\Inetpub\wwwroot" for you advanced users 5. Within the wwwroot directory locate the "localstart.asp" file. This is the same file you saw after completing the installation in the previous lesson. Your ASP files will have to go into this wwwroot directory or a contained sub-directory to run properly. This tutorial will refer to th...

Collection of articles asp Tricks of Writing ASP Scripts Running ASP First ASP Script asp sintax User Login Using the ASP Session Convert an ASP application to Perl

The following are tricks to write the good script ASP, so the application can be run properly. Trik #1 : Response.Buffer = TRUE This will lead to an ASP script will be stored in a buffer in the server and processed, if all processes have been completed, the new data will be sent to a client. This is to accelerate the execution of the overall ASP script. Trik #2 : @ENABLESESSIONSTATE = FALSE Do not use if the session is not necessary. Most web applications are rarely session requires. The use of web session will be slow because the process requires memory and a larger than if no session. By default, IIS provides session on each script executed. To turn them off, writing in the first line of each script. Trik #3 : Use adovbs.inc or adojavas.inc adequate File adovbs.inc and adojavas.inc amount of about 14 Kb. If the file is in the script include in each, will slow server, although the difference is small. Take meant only as needed, you do included if not needed. Usually that is needed in...
