Quoting my comment from a discussion thread on the AMD Community website Actually the drivers back from 2015 that Microsoft serves for AMD laptop graphics adapters seem to make Windows 10 crawl (at everything, not just in graphics stuff). Installing the newest ones from AMD (in this case the beta driver) makes laptops work decently […]...

Θαυμάστε παρακάτω ένα έγγραφο (από ΔΕΥΑ Αγρινίου, έτους 2015) που δείχνει το αίσχος με πολλές επιχειρήσεις ύδρευσης / αποχέτευσης που καταχρηστικά ορίζουν ως τριτεγγυητή για χρέη του ενοικιαστή προς αυτές τον ιδιοκτήτη ενός ακινήτου. Αναφέρει: Δηλώνω δε με την παρούσα, ότι είμαι υπεύθυνος εξ’ ολοκλήρου για την εξόφληση των λογαριασμών, σε περίπτωση κατά την οποία, […]...

I just came across this strange thing on twitter: Received a notification that some “Virginia A. Osborn” liked a tweet of mine that was a) in Greek b) totally of a subset of Greek residents interest, highly unlikely it would have meant anything to a person with a foreign name. Then I saw that twitter […]...

This will be a discussion of a possible solution with the requirement to query a large number of web services and selectively project the responses in UI and in a database. For the UI I chose the XAF application framework from DevExpress, because I wanted the tools to validate, secure, display and persist my data while I spent my time designing the service layer. For sending the web requests I introduced a service layer in my solution where I used the HttpClient class and I serialized the responses with Utf8Json . Here I want to draw your attention to the bad design of the HttpClient. This class implements IDisposable which makes you think that you can use it in a multithreaded environment and simply dispose it. However the case as it turns out is different, designed to be re-used for multiple calls, and there is a lot of buzz around ( Link1 , Link2 , Link3 ). In short if you try to dispose the HttpClient when the request is done you will end with endless debugging hours. In the previous posts there are...

In this post, we will showcase how simple it is to......

Unfortunately, Microsoft seems to have gone to extra lenghts to make the Windows Live suite of software go away, without anyone thinking that there were people who were using them and without offering file/project-level compatible replacements for user-friendly tools like Windows Live Movie Maker. Only Windows Live Writer was at some point reincarnated as the […]...

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/...
