 | This is a topic near-and-dear to my heart. Although my day job is development, I supplement my income through writing. Like other people, ads drive my crazy. Yet, in the past ads were what allowed sites to pay me quite nicely to write for them. Now we see sites giving …  |
| | People who know me know that Python has always been one of my favorite languages. And over the years, I've been pleased with the array of development tools that have been created for it, including the different IDEs. I also do a lot of work in .NET, primarily with C#. …  |
| | Every year or so for the past couple of decades I've seen new products appear that claim to let you create software without having to know how to code. And every time the next one comes out, I roll my eyes, because they always fail to deliver as promised. Usually …  |
| | [COLOR="Red"][B]UPDATE: see author's comments after article[/B][/COLOR] When you develop for mobile devices these days, you pretty much have two paths you can take: You can use the OS manufacturer's SDK and develop native apps, or you can create an application that runs in the device's web browser. Developing for the … |
| | [ATTACH=RIGHT]17428[/ATTACH]Almost every programmer knows his name. He's a living legend in computers. His name is Bjarne Stroustrup, and he created the world's most popular programming language, C++. I had a chance to ask him a few questions. The first three of the questions I came up with, and the remainder … |
| | SQL Server is touchy about the names. Depending on how it's configured you may or may not be able to just use an IP address like you're using in the connection string. When I'm faced with this, I first try to make sure I can connect to the server using … |
| | Since you're incrementing by two, you're basically skipping the final \0. Look at when you get to the 'Y'. You print that out, and then you go two more, which puts you one past the \0. So your test (letters[i] != '\0') never sees the \0. It sees the one … |
 | Re: Regexp help Here are two references for learning regular expressions, one site and one book. I recommend you get the book and study it, and also study the site. The site is www.regular-expressions.info. The book is called [Mastering Regular Expressions](http://www.amazon.com/gp/product/0596528124/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=0596528124&linkCode=as2&tag=facebookjmc-20). |
 | Do you know if there's any macro or something that will take a Word doc and convert it to Markdown? When I uploaded my tutorial a couple days ago, it took a really long time to copy and paste from the word processor, especially in places where there was a … |

 | When you have a function in C (or C++), the function gets an area of memory on the stack to use for its local variables. If you create a variable like this: MyStruct X; inside your function, then the X structure will get created on the stack. If you return … |
| | As I spend time in the Daniweb forums, I see some questions that ultimately come down to the issue of manipulating JavaScript data and a user interface on a website. When you build a GUI that lets your user view, add, edit, and delete data, a common approach is to … |
| | Do you want to actually copy the data from one table to another or just display it on the screen that way? If you just want to display it, you might consider creating a view in the database. |
 | Your code almost worked for me, except I had to change line 9 to remove the moveFromTop animation. After that fix, it completely worked: $(".navigation li a").click(function() { var currentId = $(this).attr("href"); $('.current').removeClass('pt-page-moveFromTop').addClass('pt-page-moveToLeftFade').removeClass('current'); $(currentId).addClass('pt-page-moveFromTop').addClass('current'); }); |
| | Are you using jQuery? If so, they have an example that uses the jQueryUI autocomplete and does basically what you're describing: http://jqueryui.com/autocomplete/#multiple-remote |
| | Dani, did you get this worked out? I'm not seeing this error. I'm using chrome, but I am seeing a couple other FB errors. |
| | Hi! The problem is your overflow:hidden is hiding it. Get rid of both of those (lines 38 and 53 of the CSS file). But then your layout will be thrown off, so add a min-height:83px to your body > header. Then it will work. :-) |
 | Yeah, as Pritaes said, use $.ajax and add the option cache:false. What jQuery does in this case is adds a random, unused number on the end of the query string. That effectively changes the URL, and as such the browser performs the request without caching. Something like this: $.ajax({url: 'url', … |
| | A minor update to the 1.6 version of jQuery was just released today. After a big outcry of version 1.6's changes to the way properties work, the jQuery team quickly released version 1.6.1 to make the new techniques more compatible with the older functionality, hopefully preventing sites from breaking. The …  |
| | IE9 is on the horizon, and there has been plenty said about it. But what about its web development aspects? In this article I look at its web developer tools, and decide whether I'll start using it in my own web development. Like most web developers, I abandoned IE several … |
| | Netbeans is a free, open source IDE for developing software in Java. It's been around for almost 15 years, having gotten its start around the time Java began. Version 7.0 is about to be released, and I got my hands on the Beta release of this new version. In the …  |
| | A couple weeks ago, Microsoft Research made available a project that had been under development for a while called Debugger Canvas. This is a visual tool for debugging applications where your functions appear as bubbles, similar to a database diagram or UML diagram. It only works on Visual Studio 2010 …  |
| | Back around 2004 and 2005, I had embarked on a web project that included the ability for my users to draw on a web page—or at least, that was one of the requirements. At the time, most of my web development had been server-side, with very little JavaScript. Long story … |
| | This past Summer, Microsoft announced the beta of a new product called WebMatrix. Two weeks ago, the third beta came out. But before I talk about it, I have to ask: Is this a new product? Or am I having déjà vu?[ATTACH]18093[/ATTACH]WebMatrix (one word) is, in fact, a brand new …  |
| | I've been using jQuery for a few years now, and the more I use it, the more I like and appreciate it. It seems like I'm always finding new ways to use it, and usually those new techniques result in me writing less code and ultimately being more productive. On … |
 | There were other options besides just the paper clip. There was this pretty cool Albert Einstein character. |
| | When I first started working on this article, I was originally planning on reviewing a different product, a new project from Eclipse called Orion. However, it turns out that project just isn't ready for prime time. It's still in a very early stage, and I don't feel I would do … |
| | Last week, I took a look at Node.js, a powerful server-side implementation of JavaScript. But one thing I found lacking was the way to easily create a web server. Essentially, Node is an implementation of CommonJS, which adds operating systems features to JavaScript. But Node is not a web application … |
| | [ATTACH=RIGHT]19350[/ATTACH]In the past, the word "JavaScript" usually triggered notions of buttons changing when you float your mouse over them, and images flashing, and silly animations happening in the web browser. Today, however, most programmers recognize that JavaScript is actually much more than that; it's a powerful language that runs in … |
| | When I was studying computer programming in college many years ago, I didn't imagine that our work could impact lives, particularly in a negative way. We've heard reports (mostly true) of death, dying, and destruction as a result of software problems, such as the time a plane flew right into … |
| | Last week, Microsoft released a set of tools for developing software for the new Windows Phone 7 using Visual Basic. In order to use the tools, you have to have Visual Studio 2010 Professional or better (right now the Express versions don't work, although I've heard that will change). But … |
| | [ATTACH=left]17212[/ATTACH]In the past, the word [I]embedded[/I] was limited to specialty devices that a lot of us used, but few programmers really cared about. Embedded devices meant things like the controllers on your microwave oven or the computer that ran your car's fuel injection system. There are certainly a lot of … |
| | The other day Google announced a new API console to simplify working with their various APIs. These APIs are basically REST-based calls into the Google servers where you connect through a URL, passing different parameters in the URL itself, and get back a response. The response comes back as either … |
| | [ATTACH=RIGHT]16929[/ATTACH]In a blog posting August 26, Microsoft announced that it is revising the licensing terms of its Security Development Lifecycle, moving parts of it to a Creative Commons license. Security Development Lifecycle is a methodology that Microsoft developed that incorporates best security practices at every level of the development lifecycle … |
| | [ATTACH=RIGHT]17677[/ATTACH]Here at DaniWeb, we've talked a lot about [URL="http://www.daniweb.com/reviews/review313227.html"]Intel Parallel Studio[/URL]. I recently had the chance to sit down with Intel's James Reinders, and find out more about his take on [URL="http://software.intel.com/en-us/intel-parallel-studio-home/"]Parallel Studio 2011[/URL]. Mr. Reinders (pronounced Rhine-ders) is a senior engineer at Intel and has been with the company … |
| | [ATTACH=left]17191[/ATTACH]Today at Intel's IDF 2010 was the official launch of the 2011 version of Intel Parallel Studio. Parallel Studio is a set of tools that enhance Visual Studio to support full parallel programming. This is more than just a simple plug-in for Visual Studio. It's an entire set of tools … |
| | [ATTACH=RIGHT]17350[/ATTACH]Since the release of the second edition of Parallel Studio this month, I've spent a good amount of time with it, trying out the new features. First, what's Parallel Studio? It's an add-in for Microsoft Visual Studio that gives you a large set of features for writing parallel code that … |
| | [ATTACH=RIGHT]17189[/ATTACH]I'm here at the Intel Developer Forum 2010 in San Francisco, and this has been a great opportunity for a programmer such as myself. While most programmers might think of Intel as a hardware manufacturer and look to other companies (such as Microsoft) for their development tools, in fact that …  |
| | I'm still here at the Intel Developer Forum (IDF) 2010, and just had the chance to try out something cool. The Intel Atom processors are lightweight x86 processors for use in a whole range of small devices. And being x86-based, they can run modern desktop operating sytesms. At the beginning … |
| | I'm here at the IDF 2010 conference in San Francisco, and during this morning's keynote session, I had to the opportunity to see some pretty cool technology. One of the things that they demonstrated was essentially the next generation of handheld game controllers. Think of the Wii remotes, but with … |

| | Rapid Application Development has come a long way since the early days of Delphi and Visual Basic in the mid 1990s. I remember those days well, as I immersed myself in Pascal development with the original Delphi back in 1995 and even wrote a couple of books about it. Delphi … |
| | Hi Sridhar, can you post your code so we can take a look at it? In general, if you use the AJAX XMLHttpRequest object (or a library that encapsulates the AJAX functionality), you should be fine. The object should make the call and return the results in a function, instead … |
| | With the recent release of Visual Studio 2010, Microsoft has updated.NET and the C# language, both now at version 4. One of the new features of C# is the ability to handle dynamic types. But what exactly does that mean? Essentially, if you're very careful, you can use C# in … |
| | Do you mean global.asax? If so, you can do URL rewriting inside the Application_BeginRequest function. Look up on the Microsoft MSDN site the function Context.RewritePath. |
| | I had this same situation, and if you're willing to use some JavaScript, you can write some AJAX code that will request a page. You could create a page with nothing on it, maybe call it ping.aspx. And then set a JavaScript timer to go off every couple minutes and … |
The End.
