Choosing The Right HDTV

Choosing The Right HDTVLooking to replace your old TV? Then you may might to invest in the new HD technology. Unlike regular standard televisions, HDTV sets are much lighter, occupy less space, offer more features and provide better image quality. However, the search for a new HDTV can be a daunting one, especially for new customers who are unfamiliar with the many HDTV technologies. Hence, in this article we will examine the various types of HDTVs and their benefits.HDTV CRTHDTV CRT is based upon on the old Cathode Ray technology which is found in regular TVs. Some of the benefits of this technology is its proven reliability (50+ years), picture quality and low price point. However, with this technology you have to deal with bulky, heavy TV sets, screen glare problems and limited widescreen choices. The biggest wide screen you can get for a HDTV CRT is only 34-inches.Rear Projecting HDTVCurrently there are two types of Rear Projection HDTVs. The older Rear Projection HDTV is based on the CRT technology while the newer one is based on the LCD/DLP/LCoS Projection technology. Like HDTV CRT, Rear Projection CRT offers large wide screens at a very low price point. However, you have to deal with poor picture quality from non digital signals, expensive maintenance, bulky cabinet enclosures and narrow viewing angles. The newer LCD/DLP/LCoS Projection technology offer larger screen sizes, good black levels, larger viewing angle, and great picture quality. However, with this technology you have to deal with expensive bulbs that have to be replaced every 5,000-7,000 hours.Plasma HDTVThe Plasma HDTV is a mainstream technology for viewing high definition channels. Plasma HDTV displays offer amazing color definitions, large viewing angle, good black levels and they occupy less space. However, with this technology you have to deal with the possibility of screen burn-in problems and screen glares.LCD Flat Panel HDTVThe LCD Flat Panel HDTV is the other mainstream technology for viewing high definition channels. LCD HDTVs offer wider range of screen sizes (7 to 65), greater image resolutions, are very bright, no burn-in problems and last very long (60,000+ hours). However, with this technology you have to deal with poor black levels, small viewing angle and a high entry price point.

How To Compare HTML Online

How To Compare HTML Online

If you're a webmaster to the Internet, and you want to create a slick and well built website, you might be at a loss as to how to go about it. Well, first and foremost you will need some type of basic HTML skills. While you don't actually have to be able to write HTML or get really in depth with JavaScript or any of that, you at least have to understand the nature of and be able to compare HTML tags and what each tag means and what they represent. This understanding can only be achieved by in-depth study, but there is a simple way to skip all the hullabaloo that is associated with learning to code and compare HTML and write webpages on the Internet. The user can simply go to the website of their choice that they believe is elegant and aesthetically pleasing or is otherwise well-written, such as the websites where the proper search terms and keywords are well-placed or what ever other details the user is seeking out are present when they compare HTML. Once the suitable website has been located the user can simply click on the view button at the top of the screen in their web browser and go to view > source and see the raw HTML that the website has been written in. Whatever content that the user sees on the website that he likes, it's easy enough to compare HTML and modify webpages, providing that the user knows something about how to compare HTML and the nature of the encoding.By following these simple steps, even a novice webmaster can compare HTML from assorted sites and cut and paste into a simple program such as Notepad or WordPad and doctor up all the HTML to create the effect that they hope to achieve in their webpage and coding. A unique trick with using the compare HTML technique is to take bits and pieces of different websites and combine them into a new and unique website of your own design. This takes very little effort other then the cut and paste that is included in the user's text editor software. In this way you can take advantage of the work that has preceded you and was conducted by other people by simply cutting and pasting the best bits that you enjoy when you compare HTML from other users and webmasters.It is always important to remember that webmasters should always be careful of copyright law on the Internet, as plagiarism is illegal and can be prosecuted for extreme punishments. While very few would say that stealing HTML could be construed as copyright infringement, the content and text written on the webpage itself is covered under copyright law no matter how you may translate the HTML. Using the compare HTML technique is safe and effective when used in small amounts and the technique of swiping bits and pieces from different websites and combining them is utilized. Providing that the webmaster does not steal any copyrighted material, there should be nothing but positive effects from the compare HTML technique.

Partial Page Rendering Using Hidden Iframe

Partial Page Rendering Using Hidden Iframe

Partial-page rendering removes the need for the whole web page to be refreshed as the result of a postback. Instead, only individual regions of the page that have changed are updated. As a result, users do not see the whole page reload with every postback, which makes user interaction with the Web page more seamless. Developers that want to add such behaviors to their web pages are often faced with a difficult decision. All of these actions can be implemented using a very simple solution: by refreshing the entire page in response to the user interaction. However this solution is easy but not always desirable. The full page refresh can be slow, giving the user the impression that the application is unresponsive. Another option is to implement such actions using JavaScript (or other client-side scripting technologies). This results in faster response times, at the expense of more complex, less portable code. JavaScript may be a good choice for simple actions, such as updating an image. However, for more complicated actions, such as scrolling through data in a table, writing custom JavaScript code can be a very challenging undertaking.This paper provides a solution which avoids the drawbacks of the full page refresh and custom JavaScript solutions. In this paper partial page rendering functionality provides the ability to re-render a limited portion of a page. As in the full page render solution, partial page rendering sends a request back to the application on the middle-tier to fetch the new contents. However, when partial page rendering is used to update the page, only the modified contents are sent back to the browser. This paper gives the solution using a hidden Iframe and simple JavaScript to merge the new contents back into the web page. The end result is that the page is updated without custom JavaScript code, and without the loss of context that typically occurs with a full page refresh. Introduction: Web pages typically support a variety of actions, such as entering and submitting form data and navigating to different pages. Many web pages also support another type of action, which is to allow the user to make modifications to the contents of the web page itself without actually navigating to a different page. Some examples of such actions include. Clicking on a link could update an image on the same page. For example, an automobile configuration application might update an image of a car as the user chooses different options, such as the preferred color. Selecting an item from a choice box might result in modifications to other fields on the same page. For example, selecting a car make might update the set of available car models that are displayed. Clicking a link or selecting an item from a choice could be used to scroll to a new page of data in a table. Clicking a button in a table might add a new row to the table. All of these actions are similar in that they result in the same page being re-rendered in a slightly different state. Ideally, these changes should be implemented as seamlessly as possible, so that the user does not experience a loss of context which could distract from the task at hand. Partial page rendering can be implemented with very simple solution using a hidden Iframe and minimal JavaScript. Any part of the page can be partially rendered with using a div or table tags in HTML. Page Elements That May Change During PPR: Re-Render Data: The same fields are redrawn but their data is updated. Examples include the Refresh Data action button, or recalculate totals in a table. Re-render Dependent Fields: Fields may be added, removed, or change sequence, and data may be updated. Examples include the Country choice list, which may display different address fields, and toggling between Simple and Advanced Search. Hide/Show Content: Both fields and data toggle in and out of view. Page Elements That Do Not Change During PPR: Some page elements are always associated with a page, regardless of the content displayed on the page. As a general rule of thumb, elements above the page title (except message boxes) remain constant and do not change position, whereas elements in footer constant but may move up or down the page to accommodate changes to page content. The following elements never change when PPR is initiated: Branding Global buttons Tabs, Horizontal Navigation, SubTabs Locator elements: Breadcrumbs, Train, Next/Back Locator Quick links Page titles (first level header) Page footer Separator lines between the Tabs and Page Title In most cases the following elements will also not change, other than moving up or down the page to accommodate changed elements. Nevertheless, in certain cases actions on the page may require them to be redrawn: Side Navigation, unless it contains a Hide/Show control. Subtabs Contextual information Page-level action/navigation buttons Page-level Instruction text Page-level Page stamps Page-level Key Notation In all above scenarios this solution can be used to achieve the good performance and user interaction of the web pages. Contexts in Which PPR Should Not Be Used: When PPR is implemented correctly, it significantly improves application performance. When performance improvement is not possible with PPR, it should not be implemented, thus avoiding unnecessary code bloat, PPR can't be used when navigating to another page (with a different title). Partial Page Rendering Solution: Solution provided to the Partial Page Rendering using simple hidden iframe and JavaScript, this can be used as a generalized solution to all the Partial Page Rendering scenarios. Below is the main html (Table 1.1), which will have two buttons one is to show a simple table which will be generated by the server, and another button to remove the table. [html][head][title] Main Document [/title][script language="JavaScript"][!--function showTable() {hiframe.location="./table.htm";}function removeTable() {document.getElementById("tableId").innerHTML="";}//--][/script][/head][body][iframe id="hiframe" style="visibility:hidden;display:none"][/iframe][table][tr][td]Table::[/td][td][/td][/tr][tr][td colspan="2"][div id="tableId"][/div][/td][/tr][tr] [td][input type="button" value="Show Table" onclick="showTable()"][/td] [td][input type="button" value="Remove Table" onclick="removeTable()"][/td][/tr][/table][/body][/html]Table 1.1[iframe id="hiframe" style="visibility:hidden;display:none"][/iframe]This iframe tag is used as target to the Partial Page Rendering Request. The tag [input type="button" value="Show Table" onclick="showTable()"] gives the user action to get the contents of a table from the server, in this solution sample html is provided to render the table, which supposed to be generated by the server. The tag [input type="button" value="Remove Table" onclick="removeTable()"] gives the user to remove the table from the user interface.The JavaScriptfunction showTable() {hiframe.location="./table.htm";}Is used to get the contents from the server, the line hiframe.location="./table.htm"; sends the GET request to the server, and as a response iframe gets the HTML. If the requirement insists to send a POST request for Partial Page rendering Response, that can be achieved by setting the html form element target attribute as the name of hidden iframe. The code for the post request looks like [form method="post" action="/myaction" target="hiframe"] Partial Page Rendering Server Response: Table 1.2 shows the sample response from the server for Partial Page Rendering. This response has the JavaScript code to transfer the HTML from hidden iframe to main page. [html][head][script language="JavaScript"][!--function iframeLoad() {parent.document.getElementById("tableId").innerHTML = document.getElementById("tableId").innerHTML;}//--][/script][/head][body onload="iframeLoad()"][div id="tableId"][table][tr][td]1[/td][td]One[/td][/tr][tr][td]2[/td][td]Two[/td][/tr][/table][/div][/body][/html]Table 1.2The tag [div id="tableId"] encloses the content to transfer from hidden iframe to main page.[table][tr][td]1[/td][td]One[/td][/tr][tr][td]2[/td][td]Two[/td][/tr][/table]This is the content to show the table to user.The code [body onload="iframeLoad()"] is used for triggering the action to transfer the content.function iframeLoad() {parent.document.getElementById("tableId").innerHTML = document.getElementById("tableId").innerHTML;}This JavaScript function does the transferring data from the hidden iframe to main page. parent.document.getElementById("tableId").innerHTML This part refers to tag div html id in main page and this part document.getElementById("tableId").innerHTML refers the HTML of the Partial Page Response. Conclusion: Improve the user experience with Web pages that are richer, that are more responsive to user actions, and that behave like traditional client applications. Reduce full-page refreshes and avoid page flicker. Partial page rendering using iframe is a very simple solution.

Techniques For Integrating Hibernate Into Legacy Java Code Part 1

Techniques For Integrating Hibernate Into Legacy Java Code  Part 1

If you're like me, you spend a lot of time dealing with legacy code that, for whatever reason, does not take advantage of modern methodologies and libraries. I've taken over Java projects that contain hundreds of thousands of lines of code and not a single third-party jar other than a JDBC driver! One of the most common examples of this is the implementation of the data access layer. These days, the de facto methodology involves Hibernate and DAOs, usually managed by Spring.This article will detail the steps I recently took to covert a large application from custom-written data access to Hibernate and Spring using the refactoring facilities in Eclipse. The key with this refactorization is to get the existing business logic code (Struts Actions, JSPs, Delegate classes, Business Service classes, etc.) to access the datastore using Hibernate, managed by Spring, without manually changing any of that code directly. Part 1 will include creating the Hibernate data object classes, DAOs, and refactoring the existing code to work with these newly created types. Part 2 will conclude the project with integration of the Hibernate DAOs and wiring everything up with Spring.First of all, we need to create our Hibernate model and DAO classes. Obviously, since we're dealing with a legacy application and data structure, we will want to use a bottom-up approach to building our data access layer. This just means that we're going to generate the Java code and appropriate Hibernate config files from the existing database. There are many tools freely available to make this process very painless. I recommend an Eclipse Plugin for creating and maintaining the Hibernate artifacts (Google Hibernate Eclipse Plugin to get started). The structure and requirements for creating Hibernate classes and config files are well documented elsewhere, so I won't go into detail here. However, in this particular project, the Hibernate DAO lifecycles are managed by Spring, so the DAO classes should all extend HibernateDAOSupport.Now we have java classes (POJOs) which map to our database tables, but none of the existing code uses these new data object classes. This is where the refactoring tools of Eclipse comes in really handy. For example, say we have a legacy class called AccountInfo which corresponds to the ACCOUNT database table. Right-click the class and select Refactor -> Extract Interface. On the dialogue box, call the new interface IAccount and make sure you select Use the extracted interface type where possible. Choose the other options according to your preferences. Click OK and kick back while Eclipse changes every occurence of AccountInfo references to IAccount references and recompiles. Of course, do this with each object model class.If you never realized why OOP languages are so great, you're about to. Now we're going to refactor the code so that all of the existing legacy can be hooked into the new Hibernate model classes instead of the legacy ones. Continuing with the AccountInfo example, create a new class you'll probably want to create a new package for this step called Account that extends the Hibernate POJO for Account and implements the new IAccount interface.This next part is the most time-consuming, but really isn't that bad. At this point, the newly created class will probably contain a bunch of empty methods containing only TODO comments. This is because the IAccount interface most likely defies a bunch of methods that are not implemented in the Hibernate Account POJO. To deal with these, we basically want the new Account class to delegate to its generated superclass whenever necessary to satisfy its contract as an IAccount type. As a real world example from the application I was working on, the legacy AccountInfo class defined a getter/setter pair for a property called username, whereas the corresponding column in the ACCOUNT table was actually LOGIN_NAME. To deal with this, you would simply implement the get/setUsername methods in Account to delegate to get/setLoginName (from its superclass). I also had to translate between various data types quite a bit. For example, the legacy code would define many properties as Strings even though the corresponding piece of data in the database was defined as an INT or TIMESTAMP. Again, do this with each object model class.To finish up the data model layer, edit the appropriate Hibernate and Spring configuration files to refer to these new object model classes. The application now has the ability to map database records to Java objects via Hibernate, and the legacy code which refers to these classes has not required any editing by hand. To finish up this refactorization project, we need to hook in the Spring-supported Hibernate DAOs in a similar way. In Part 2 of this article, I will discuss refactoring the legacy code to read, write, and update data using Hibernate and Spring.

A Crash Course On Myspace For Parents

It is easy to lose track of what your kids are doing online without being overly snoopy about their growing independence. Independence is a good thing when the child has demonstrated that they can make responsible decisions and good choices. Part of your responsibility as a parent is to provide the tools which will help them along this pathway. A good way to open communications with your child is to discuss the MySpace internet area with them. MySpace is a web site where teens and preteens can journal thoughts, add pictures, chat with others about their interest, and discuss events and problems which affect their daily lives. A great deal of controversy lately has surfaced around the site, because of the potential for unwelcome elements of discussion, pedophiles who may use the site as a springboard for meeting youngsters face to face or other unhealthy aspects. By understanding the mechanics of how MySpace works, parents are enabled to sit down with a preteen child and dialogue about the positive aspects of the web site as well as opening discussion about the dangers which can be found. Obviously, no parent is going to be able to totally block off any areas of the internet which might be perceived as unhealthy for the child. Often such actions will either be resented as overly controlling, or will create an interest where none existed previously. Some important tips to use with your youngster is how to set privacy and profile options for security online. You can also explain to your child the importance of not lying about your age, or giving out the real name of your school or other identifying information. The important part of this exercise is that it is done jointly with the child, so they learn not only how to use guidelines in making decisions, but that there are good reasons for the guidelines.

Keeping Management Membership Site Software Your Business Alive On The Web

In the vast competition on the internet money-making industry, keeping your website with a membership site running is the most popular way to keep you alive in the business. A membership site will somehow increase your chances on the web to make it big, and if by luck, will continue being so for the coming, long years. However, a membership site will not stay long in the industry if you don't have the membership site software to run the organization properly. The membership site software is a way to keep your members glued on their commitments with your organization, so it is essential that you largely consider it as your primary tool in keeping your website. If you are just staring with your membership site and you are hoping to make it really big in the industry, make sure you choose the most appropriate membership software that can manage well your organization in tracking your members. The following should be considered in selecting your own membership website software:1.Reliability this tackles about how the software is going to be effective with your website. It should not only focus on the reliability of the software alone but on the company that supplied the membership website software as well. You have to look for a company which will offer the best services such as being available 24 hours a day and will always provide you solutions.2.Actual features you have to learn of these things before picking the software. There are many software programs you can choose on the web but they are not the same. A "membership software" website may have features that are unnecessary with your website while the other may lack some that you need. Check them all and get one with features that will largely compensate on your needs. 3.Compatibility some membership software runs on PHP on the server, while others run on ASP. In this aspect, check one that would be compatible with the web host account that you have. 4.Price of course, this is the most indispensable factor that you must take into consideration. Membership site software programs can be quite expensive. If you do not want to waste even a cent, do not spend on an overly expensive software which features a lot of things but you have no need for in the end. On the other hand, you do not have to spend on cheap software if it lacks the necessary features you need for your organization. If you have analyzed these factors, you will find a membership software program that will surprisingly meet your needs but without spending exaggeratingly. For a starter, you will find a program which costs at a very reasonable rate. If you have stepped further in the business, then you can upgrade the software so you will be able to manage the membership you have collected. Membership management software is the most ideal program which most organizations and associations employ. It allows you to keep track of your members even without you supervising it on hand. Most membership management software applications are available with features that will keep track of the details and information of your members by sending them regular emails to the account they have provided. Membership management software is very accurate in the sense that it can keep the status of your members updated. It will help you keep your members; thus a steady flow of the traffic.
