On Windows 10, Microsoft (they’ve acquired Skype some years ago) provide a Windows Store app for Skype, however Universal Windows Platform (UWP) apps like that one don’t support older webcams (even the ones embedded in not-that-old laptops). Unfortunately, Microsoft hasn’t bothered to provide some frame grabber driver to bridge with DirectShow-based etc. older webcams that […]...

I am happy to announce the new ExcelIMporter module for both Windows and Web. Released with eXpandFramework v17.2.6.3. Importing is a complex task, each scenario has difference requirements. So, first off, a short brief on the existing importing solutions found in eXpandFramework. The ImportWizard module This module was contributed to eXpandFramework a few years ago from a community member. Pros Beautiful UI as it is build with the same DevExpress components that XAF uses. Well integrated, with localization support and skinning. Imports in batches on a background thread. Visualization of the Excel Sheet for configuring the import. Cons It is not a native XAF implementation but a Windows Forms integration into XAF, which makes it really hard to support and harder to EasyTest. Import configuration cannot be reused. Does not support the Web. Poor notification of importing errors. Can only import *.xlsx files. The IO module This module was designed to help move objects graphs in the form of XML out of XAF and again...

I was looking for a way to show a hidden HTML element with just CSS (no Javascript) when mouse hovers over an anchor (say over a “more…” note), while at the same time also supporting touch-only (no mouse) clients, where clicking should show (and keep open) that same element. I ended up combining solutions and […]...

After doing sudo apt-get update sudo apt-get upgrade on an older Raspbian installation (at a 4GB SD Card), some corruption occured (probably due to lack of space, since I see newer NOOBS asks for an 8GB SD Card), making it unbootable. Would only show the NOOBS splash screen, but couldn’t boot into Raspbian. I just […]...

XAF offers mobile support long time and the XAF team is constantly adding new features and modules, I guess the out of CTP mode is close enough. So its about time to support the mobile platform from our community project (eXpandFramework). Long story short: eXpandFramework up to now only recognized two contexts (Win, Web), this will change from v17.1.5.2 where a Mobile context is introduced. What this means for you? At the moment there are no new mobile modules released, however you are now able to use eXpandFramework your agnostic modules that reference eXpandFramwork in the mobile platform. p.s.: All easytests for the Win, Web platform still pass on every release, but at the moment there are no tests for the mobile. but its on schedule. Looking forward for your feedback at http://www.expandframework.com/forum/...

Those of you that use Remote Desktop connection you probably noticed that some key combinations like CTRL+ALT+UpArrow are not passed to the client. I looked everywhere but I could;t locate a ready solution so in invented one with the use of AutoHotKey . Install AutoHotKey on both machines and create a Autohotkey script (a file with ahk extension) for the host machine and enter: *^LAlt::^AppsKey This will replace all key strokes that use the left alt key with the Control + AppsKey(the one that opens the context menu when right click). and for the client machine similarly to switch back you need a second script with the following command *^AppsKey::^LAlt I am using this workaround for a week now with no issues, hope it helps some of you. p.s. : if you have a better way, please post in comments enjoy!...

Enumerations are a simple and efficient way to deal with a set of values. The most common way to use an enumeration is to use its values separately. There are however times when we want to use a combination of the enumeration's values. In that case we can use bitwise operators. To make things easier, we can also use flags. Enumeration Let's start using a simple enumeration example. Enumerations are structs consisting of a set of values the type can be assigned. So let's use an enumeration of payment methods. Here's the enumeration. public enum PaymentMethods { None = 0, Cash = 1, Cheque = 2, CreditCard = 3 } We can now use this enumeration to connect PaymentMethod values with their integer representation. For example int creditCard = 3; PaymentMethods creditCardMethod = ( PaymentMethods )creditCard; or int creditCard = ( int ) PaymentMethods .CreditCard; It is...

You do not have to be working on some gambling project in order to request for a random number. Things like that happen all the time. Either you may need to pick a random product to show out of a list or you may want to present some results randomly ordered. Anyway, getting a random number is something you will need to do from time to time. To get a random number we may use the Random or the RNGCryptoServiceProvider class. We are going to find out what is the difference between them and talk about what makes a random number. Randomness Let's start with the basics. What makes a random number? A number is considered random when there is no method to predict what that will be before it is presented. You may think of this as something obvious, however it is not. Let's say someone asked you to pick a number between 1 and 10 and you picked 5. Why would that be? Maybe that is because you like number 5, or you like the fact it is located in the middle of the 1 to 10 range, or because of a subconscious...

All around C#, there are over a few dozen keywords. One of them, which is rarely used and is sometimes misunderstood, is yield. However, if used properly, yield can help in optimizing your code. Let's take a look at how it works. What does yield do? Let's get to what yield does using an example. We are going to create a method that returns a Fibonacci sequence. You have probably heard what Fibonacci numbers are, from your first for loop classes. So, a Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding numbers. Well, this may not be the exciting way you would expect to implement yield, but I guess this will make things easier to grasp. So let's write the following code. string fibonacciSequence = ""; foreach ( int f in FibonacciEnum(10)) fibonacciSequence += f + " " ; The following method returns a Fibonacci sequence. private IEnumerable...
