More free stuff from DevExpress…
In a previous post I had mentioned about 60 free .NET components available at no cost at all. These are high quality controls and I still have to try many of them. Well, looking for a Silverlight Datagrid, I came across Devexpress again and noticed they are offering these two compoent sets for free, including their source code. Silverlight Datagrid Control – here Silverlight Menu – Toolbar controls – here I used to love Xceed andComponentOne controls, but they are expensive and Devexpress has become one of my favourites since they make it nearly impossible not to try/use their components and become a fan of them… I just thought I’d post this, because there aren’t many Silverlight Datagrid controls and this one is free. I will likely be doing some experiments with these controls, as soon as I am done with another Silverlight experiment I am working...

What is the Windows Key for…?
I don’t know…it is just a key that doesn’t seem to do anything when pressed and it is just in the way. So many years staring at it and wondering what it was good for. Well, it appears this little key is actually quite useful, as I have recently learned. By combining the Windows Key with other key, it allows you to perform frequently used task with hardly any effort. For example, to launch Windows Explorer, you may go to Start > Accessories, etc or maybe rightclick the Start button and select Explore or…… you could just hit Windows Key + E. That simple. Check out this list of shortcuts that I am sure you will start using, if you didn’t know them already. [Windows Key] + L: Locks the workstation [Windows Key] + E: Launch Windows Explorer [Windows Key] + Tab: Cycle through the buttons in the Task Bar. [Windows Key] + R: Launch the Run dialog box [Windows Key] + Pause/Break: Launch System Properties dialog box [Windows...

Silverlight Error when adding objects
I have done a couple of Silverlight experiments where I programmatically generate objects on the fly and then attempt to add them to the Canvas. In one scenario, I was trying to generate 10 circles, give them some properties and then add them to the parent object, a Canvas, in this case. However, when I did this, I got the following runtime error: “{System.ArgumentException: Value does not fall within the expected range.” right when I try to add the instances to the parent (Children.Add()). I wasn’t able to find out exactly why this is happening, but after some digging, I figured that this happens because the newly created object instances have not been given a name and therefore the runtime cannot dynamically add two instances with the same name, or no names, for that matter… So, to avoid this run time exception, all you have to do is to give your newly created instances a name, thus, in our case, simply add: e.SetValue(Canvas.NameProperty, <name>); to your loop… for (int...

Microsoft Silverlight 2.0 Progress…
Although it is undeniable that Silverlight has made quite an impact and, apparently been embraced without much resistance, it still has a long road ahead to catch up to its rival: Flash. As Scott Gu points out in his blog, more and more Rich Internet (and non-Internet as well) Applications are being written in Silverlight and the technology is becoming mainstream with the big names. On the other hand, Flash has clearly the upper hand. More than 10 years in the business and a platform that can be embraced by non developers, gave them a long early start. Just looking at the demand for developers in either realm on Monster.com gives you the picture: Flash (2241) vs. Silverlight (178). A few good articles comparing these two platforms can be found here, here, here and here. So, as a developer familiar with both technologies, on which one would you...

Free physics textbook
How does a rainbow form? Is levitation possible? Do time machines exist? What does 'quantum' mean? What is the maximum force value found in nature? Is 'empty space' really empty? Is the universe a set? Which problems in physics are still unsolved? Motion Mountain publishes a free, online, physics textbook that tells the story of how it became possible, after 2500 years of exploration, to answer such questions. The book is written to be entertaining, surprising and challenging on every page. With little mathematics, the text explores the most fascinating parts of mechanics, thermodynamics, special and general relativity, electrodynamics, quantum theory and modern attempts at unification. The essence of these fields is summarized in the most simple terms: it is shown how they are based on the notions of minimum entropy, maximum speed, maximum force, minimum change of charge and minimum action. The text explores the limits of time and space, and the wonders that can be discovered there. Written in English, its over 1200 pages are provided for...

Windows XP useful shortcuts
I thought I knew most of the keyboard shortcuts that my operating system provides me. What other shortcuts are there besides control-X (cut), control-C (copy) and control-V(paste)? Yes, there is control-Z (undo) and a few others, but that is pretty much it (so I thought…). It appears there is a long, long list of quite useful keyboard shortcuts that I will now have to remember. This article describes them in detail. Read more:...

FTP Add-in for Visual Studio 2003
One of the deficiencies I have found in Visual Studio, when writing ASP.NET applications, is that it has no built-in method for uploading your project or files to a remote webserver. I write the code and test locally, but more often than not, I test directly from the webserver. I had resorted to using Dreamweaver as a code editor and using its FTP features to upload the required files. Ofcourse, I would miss out on the features that VS does have for ASP.NET….Then I found Unleash It! The latest version includes a stand-alone version, a Command Line Version (useful for scripts or processes) and a Visual Studio .NET 2003 Add-In. The Add-in allows you to right click on your project and select "Deploy it", which will FTP only the required files to the webserver. read more:...
