tech sectiontech sectionAn XML file may contain a document type declaration (DOCTYPE) reference that helps the user's browsing agent identify what type of document the Web browser is loading. The most common DOCTYPE is HTML. However, occasionally, you may need to create an XSL file that ignores the DOCTYPE reference in your XML files. You can do this by setting up a dummy document type definition (DTD) file that your XSL file leads to, bypassing the XML DOCTYPE.
If your Visual Basic program is getting a "failed to connect to the server" message when you try to access Google's servers, your problem lies with establishing the connection itself and not with any authentication issues. You can start troubleshooting this issue by checking own firewall settings and the arguments you are feeding into your library object.
The Apache JServ Protocol was created by the Apache Software Foundation as a means of communication between Web servers and servlet containers. The Apache JServ Protocol can be used with Apache's Tomcat server interface, as well as other supported container types, such as Jetty.
Apache Nutch is an open-source Web crawler application written in the Java programming language. It was developed by the Apache Software Foundation. To use the Apache-developed crawler, you must have Apache Tomcat and Java 1.4 by Sun or IBM installed on your Linux computer. Once installed, use Apache Nutch as a Web crawler to seed a database with a list of a website addresses, just like Internet giants like Google and Yahoo do with their search engines.
InvisionFree is a free online service that lets users set up their own customizable online forums. Once users have signed up on the site and received their forum, they can then change the look and feel of the forum using an HTML skin. You can skin your InvisionFree forum in the Admin CP section of your forum. Many skins are available in the InvisionFree resource section. Once you have found a skin that you like, you can copy the skin HTML code into the provided areas in your Admin CP area and save the changes to display a new skin…
Typography makes a difference in the usability of your Web pages. This problem is complicated by the variety of font size options available in CSS styles. Instead of defining your fonts in pixels, you might consider converting them to points, or perhaps a more user-friendly measure such as ems or percentages.
The Expect computer scripting language derives its name from the primary function of the language, which is to expect user input from an interactive program and automate the response. Expect is primarily used in systems-administration type activities, where an administrator may need to periodically interact with another system in a formulaic manner. One common keystroke in systems administration is "Ctrl-C," typically used to abort a process. Expect is designed to automate any typical key or combination of keys that a system administrator might enter.
You can use an online conversion tool or download a free utility to convert your HTML table to an XML format for use in a data grid. HTML files often have extraneous coding attached to them, which prevents them from being readable by applications that require XML code. The tools available to perform this conversion, however, are able to strip the unneeded coding from the HTML table, and restructure the document in a format that is useful for projects needing XML code.
You probably won’t need to store an entire dictionary in a single PHP string, but it can be useful to know exactly how much data you can assign to a single variable. Although there’s a practical limit to the amount of data that you can store in a PHP string, you can conveniently alter that limit by editing a particular file.
Adding hypertext markup language (HTML) tags to your signature lets you format the way your signature will be displayed by your contacts' email client. SME Server is an email server application that lets developers create their own webmail portal. Users of this portal can both send and receive emails from within their Internet browser. You can add an HTML signature to the emails you send within the SME Server webmail interface by editing your account's preferences.
Once you learn to perform asynchronous Ajax trigger processing, you can make your ASP.net webpages more interactive and useful. Microsoft Visual Studio contains helpful Ajax controls that allow Web pages to refresh their data without communicating with the Web server. This type of asynchronous communication enables your site visitors to interact with controls that display new data instantly. Create a digital clock, for example, by refreshing a label every second. After setting up Ajax controls, you only need to create a few lines of code to refresh elements on your ASP.NET Web pages.
The Python programming language makes it easy to install and run new software or developer tools, but it won't seem that way if a "header error" is interrupting your installation. If you are getting such a message, it means that the software or library modules you are trying to add to your computer have unmet dependencies. Adding the necessary files to your computer generally resolves the issue.
Just because you have the Java Development Kit (JDK) installed on your system does not mean you will automatically be able to compile Java source code with different development environments or build tools. If these tools are not correctly configured with the location of the JDK, you will get error messages that end with "JAVA_HOME does not point to the JDK." You will need to configure the tool with the JDK's directory address.
Applying borders to your HTML elements, like images or quotes, helps to differentiate the object from the rest of your site similar to how italicizing text draws your reader's eye to a word or phrase. You can use a combination of italics and borders on regular text, lists or links, and these styles should work together. However, improper syntax or organization can cause conflicts, such as a border disappearance.
The genius of a computer programming language, like an idea whose time has not yet come, is often not seen until a need arises that it alone can address. In recent years, both Lisp and JavaScript have been increasingly recognized as languages suitable for developing server and client applications for the Web. You can get the best of both these languages by embedding Lisp functionality into JavaScript.
The PHP scripting language gives the programmer the ability to delete files on a Web server using the “unlink” function. Technically, unlink does not physically delete a file from a storage device; instead, it removes the file's name from the list of files maintained by the operating system. Later, the operating system frees the space held by the file so it can be used by other data. If you are not careful, you could inadvertently delete the wrong file. Avoid problems with the PHP unlink function by using it cautiously and correctly.
Autodesk's Maya modeling and animation software provides users with a number of powerful tools for 3D scene creation and character animation. To enhance the user experience further, Maya allows users to create automated scripts to perform a number of program functions. Unfortunately, improper syntax and other problems in some scripted expressions occasionally cause errors and result in crashes when the script is run.
The Perl programming language has been in continuous development since its initial release in 1987. Each new release adds additional features, bugs fixes and interpreter performance enhancements. Some changes, though, mean that scripts written for older releases may no longer work as intended. Nevertheless, the corrections and syntax changes introduced in the transition from Perl 5.8.8 to version 5.10 also bring the language closer to the next major release: Perl 6.
Prompt loading of your WordPress blog not only improves your readers' browsing experience, it can also boost your blog's ranking in Google search results. Two popular caching plugins, DB Cache Reloaded and WP Super Cache, offer different approaches to speeding up WordPress sites. Used together, they may further improve your site speed.
JavaScript programming for websites relies heavily on the use of objects in the coding language. Improperly coded objects, or objects that are incompatible with a Web browser, can cause issues for website visitors trying to access information contained in the object. In Internet Explorer 8, the error message "invalid pointer error" typically indicates that a problem exists within the JavaScript code.
Hyperlinks in an HTML page are normally written as plain text, which creates a one-to-one connection between displayed text on the page and the resulting link. Some pages may instead require a randomized link, which causes displayed text to link to a random page. This can be accomplished using JavaScript or an alternative Web programming language.
XML, an acronym for eXtensible Markup Language, may appear simple at first glance, but well-formed XML must adhere to a number of strict rules. When these rules are violated, XML parsers such as MSXML and XERXES report errors that often confuse beginning coders. For those who encounter “duplicate attribute” error messages, understanding a few basic coding concepts will help illustrate the differences between elements and attributes.
Login pages provide an easy way to identify and verify access to websites, but the code to validate and manage users, passwords and credentials can quickly add up to several hundred lines of code. User profiles also require database storage and server side scripting using PHP or some language other than HTML or JavaScript. Fortunately, there are a variety of open source packages that implement these features. Here are a few tips to find the best multiple user login package for your site.
Microsoft unveiled the eighth version of its Web browser Internet Explorer, or IE8, in March of 2009. Earlier test versions of IE8 hit the market nearly a year earlier. Since this initial beta release, users have complained of several compatibility problems between IE8 and the programming language JavaScript. You have multiple options to resolve these problems.
Some especially tech-savvy users of Android phones are aware of the power of the OS at the core of these devices and seek to use it to its maximum potential. One of the ways to do this involves gaining administrative access to the phone and installing applications such as GScript. GScript allows you to write Linux shell scripts directly to the phone.
Many websites and online services use JavaScript code to deliver interactive features, including prompts that require users to input text and number characters into an online form, or password and username input fields. Some websites configure the JavaScript prompt’s text field with a maximum character limit.
Parsing a string means analyzing it for specific occurrences of characters or words. You can parse a string in Java by creating a delimiter -- a set of characters called "tokens" that identify where to break up the string -- and then calling the Java "split" function as a parser. This function uses the delimiter to break up the string and save the results in a string array. The split function lets you break the string at every occurrence of a delimiter, or, alternatively, you can specify a maximum number of breaks. Learn the ins and out of the syntax,…
An auto-blog helps you show the latest news on your blog by importing and displaying data from a feed. You use the Ajax language within your HTML pages to retrieve the data and display the content on the Web page. You can parse parts of the content or display the complete content on your pages.
Hibernate is a free tool you can use for programming in Java that allows you to map from an object-oriented domain model to a relational database. What this means is that Hibernate serves as a query and retrieval tool that allows you to move information from one type of database to another. You can also use Hibernate in conjunction with Java's scroll function -- allowing you to scroll through the mountains of data to find exactly what you're looking for.
Java is a component that is installed on many computers and is required for some applications or websites to run correctly, including the streaming-video service from Netflix. Errors like this can occur and are often resolved when you update Java or disable any proxies that may block Java from deploying on your system.
Your website is an online point of contact between you and your readers, whether they are potential customers or viewers looking for specific information. If your website readers have questions, concerns or want to contact you, mailto forms created in Adobe Dreamweaver provide an alternative to the standard email link. While a mailto form is a good tool to use when obtaining specific information from readers, it also has a few faults to consider.
Visual basic is a common programming language used in a variety of applications. The language can be used in Lego Mindstorms robotics kits to create various applications. These kits come with programmable computers known as "bricks" that control the robots. The software for these kits can be programmed to create a power-up or start-up program for the robot.
Before the Unicode standard, using special characters or letters from foreign languages meant switching between several different character sets. The convenience, however, is of little use to you if your PHP scripts won't correctly display text that is formatted with Unicode or your mySQL database won't accept Unicode text. Changing your formatting configurations will resolve these issues.
Your browser has to know it is looking at HTML code before it can parse it appropriately. If people visiting your sever see HTML source code or random characters instead of a properly parsed page, then you have a configuration issue that is preventing your server from attaching the correct formatting data to HTML pages.
Python's "urllib" and "httplib" modules simplify the process of establishing connections to remote servers but, like any tool, they will only work when you use them correctly. If your Python code is giving you a "nonnumeric port error" then you are either trying to pass nonintegers as port numbers, or are using the wrong method to pass authentication data.
JavaServer Faces (JSF) built upon Oracle's earlier JavaServer Pages (JSP) technology. Whereas JSP focused on using Java code to create Web-based interfaces, JSF takes a more modular approach to mirror cascading style sheet (CSS) syntax. JSF is a newer framework than JSP, but it still grew out of the JSP project. Consequently, you can execute JSF code segments through the JSP framework by including the code in a JSP Fragment (JSPF) file and importing it into your main JSP source code with an "include" directive.
A look book is a collection of photographs or sketches that are compiled to give a depiction of visual products or ideas, such as a fashion line or a photographer's, model's or artist's work. You can create a digital look book using Dreamweaver to add photos and descriptions to a Web page. By creating a digital look book, you can make it easy to access over the Internet; viewers can simply go to the Web page and scroll down the page to view the digital look-book contents.
In the course of regular use, operating systems and software create a surplus of unnecessary files, which can slow down your computer. If you encounter scripts that say they can tidy up files from particular types of software, you are right to be concerned that the script may be malware in disguise. You can take steps, however, to confirm the safety of a tidy script.
Website programming code must be optimized to work with many different Web browsing programs, such as Firefox or Safari. Sometimes, coding incompatibilities will affect the settings of one browser so that users don't have the same level of access as users of another Web browser. PHP code intended to create user sessions for shopping carts or profiles saved on a website is sometimes incompatible with certain security features included on Internet Explorer 8.
If you want to develop for the Android platform using a dynamic, interpreted, open source programming language, you must use Ruby. However, Ruby does not work on Android devices by default. To utilize Ruby on the Android platform, you must use Ruboto, the common language that brings them together. Before you can use Ruboto, however, you must install Android NDK, Android SDK, Ant and Java JDK.
PHP and JSP are server-side scripting languages. While it is difficult to determine the exact percentage of websites that use each of these languages, it is clear that one is used much more widely than the other is. One reason for this disparity is that the two languages are used by two different groups of website developers.
With the Vim text editor for UNIX and Linux, you can write PHP code from the command line. This is useful if you are trying to change code on a website from a remote location. You can configure Vim to automatically indent your PHP code by using a script.
A script, or a collection of instructions stored on a server, can't expire on its own. A script is capable only of behaviors that it's programmed to exhibit, and won't perform other behaviors, such as disappearing from a server. When you understand how scripts are essential for functional dynamic Web pages, you understand why it's undesirable for scripts to expire on an arbitrary date.
You can create customized shell scripts in Linux to order the operating system to perform specific commands. You can load these commands into the list of startup programs to force the OS system to perform the scripted function each time Linux starts. If you want to alter the volume level at startup or swap out the existing startup sound and replace it with a different one, you can configure these options in your own volume script in gedit, the default text editor. Alternatively, you can use any editor of your choice, such as Komodo or Bluefish.
Unlike Java's more specialized input objects, an InputStream object lets you work with byte-level data from a given resource. It is, however, only capable of reading in a static file of data. If you want to use data from another running Java project in an InputStream object, you have to use a network framework to retrieve the data before storing it in the InputStream.
Small programs are fine for teaching students the basics of the Java programming language, but are not representative of real programming work. This is why students who are getting ready to graduate from computer science programs have to complete mega projects: large scale projects that produce something that is both novel and genuinely useful.
Mobile Web browsers require different HTML and CSS presentation to accommodate the smaller screens used on handheld devices. This is frequently accomplished by using Web redirect instructions that detect the browser making the request, then return an alternate Web page with a design for that application and device. This can be done with CSS styles, Web server URL rewriting or with a Web programming language.
IWeb is a Web development application that comes with many distributions of Apple's iLife productivity application suite. Unlike designing in most other Web development programs, designing in iWeb is done using a graphical user interface. Once the website is designed to your liking, iWeb generates the HTML code for the website. If you want to create the HTML code for a Go Daddy website, you can do so directly in iWeb '08 just as you would in any other version of iWeb.
Drupal is a content-management system based on the PHP scripting language and databases that can help you to operate a dynamic website or blog. By default, Drupal allows you to use free themes but if you're converting a website from plain HTML to Drupal you can insert PHP snippets into your existing pages to create your own custom theme.
HTML code offers methods for inserting external objects as well as white space. To insert an object, you'd insert a "src" attribute into an appropriate tag, while to add space between characters of text, you'd insert an "nbsp" entity. Working together with the rest of your code, they're both important elements for Web design.
