• How to profile LINQ to Entities queries in your asp.net applications - part 2

  - by nikolaosk

  In this post I will continue exploring ways on how to profile database activity when using the Entity Framework as the data access layer in our applications. I will use a simple asp.net web site and EF to demonstrate this. If you want to read the first post of the series click here . In this post I will use the Tracing Provider Wrappers which extend the Entity framework. You can download the whole solutions/samples project from here .The providers were developed from Jaroslaw Kowalski . 1) Unzip...(read more)

• Backward Compatibility with Silverlight 4 applications

  Each release of Silverlight it is the goal to make sure existing Silverlight applications continue to work. Since I think what this means causes some confusion Im going to do my best to explain what we mean by this. Silverlight 3 application working with Silverlight 4 Okay, scenario 1 is I have a Silverlight 3 application (XAP), will that still work as-is in Silverlight 4? Yes, this is the situation we refer to as backward compatibility. What this means is that existing compiled XAPs under previous...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Can desktop applications be written using javascript?

  - by jase21

  Is it currently possible to write desktop applications using javascript, html, css? Possible solutions: Use Adobe AIR runtime and program in js. But no, if I'm using AIR, the AS3 suites it the most. So not a good option. GWT: No because it uses Java and then convert it to js or what ever. Pyjamas: Interesting. But I'm currently focusing on JavaScript. So I don't want to use python and cross-compile to js. Run a local server and use the browser in full screen mode. Sort of okay, but still its the same browser thing. And difficult to distribute. So what is the best option? I'm excited about node.js which is the main reason for looking into JavaScript. Otherwise I would have choose python.

• SUN Java and GPL V2 licence issue for linked applications

  - by user255607

  I have recently noticed that the Sun Java code has been released as GPL V2 code (see Google code repo). Does that mean that all applications written in Java and linked to Sun APIs (beans, and so on) are also in GPL ? If we strictly follow the GPL then this should be the case (Libs should be in LGPL, not GPL if we want to build proprietary software on top of it). Is there another commercial licence which can avoid such an issue ? I cannot believe this is the case. There must be an explanation on this. Regards, Apple92

• play sound from different applications on different output devices (speakers, headphones)

  - by Mike

  I want music (played e.g. via Audacious) to be played on speaker system, and all other sounds produced by other applications (including ubuntu sound effects) to be played on headphones. My computer has sound connectors at its back, and also connectors on its front panel. When I connect both headphones and speakers, only headphones work (I take it, the front connectors take precedence?). Should I purchase another sound card (in addition to the motherboard-integrated sound I have)? When I go to Audacious output settings, I see only the ouput plugin selection list, with PulseAudio selected and options like ALSA, OSS4 etc. But there's no facility to select particular output device (and I guess it wouldn't magically appear even if I had the second soundcard). Is this at all possible to bind specific application to particular output device?

• Stop myself from over-complicating applications

  - by stuartmclark

  Recently I worked on a fairly large project involving C# and MVVM. This application had around 160 projects in the solutions each seprarated into their own layers. As I have been working on this application for almost a year, building it from scratch as part of a team, I am now coming off that project and onto smaller more trivial projects. As I was beginning to develop a small in-house tool I found myself trying to mimic the larger applications structure and layering but in the end I just had a simple application with several DLLs which I know I wouldn't have done if I had not worked on that larger application before. I am just wondering if there are any techniques I can utilise to stop myself from turning a "code-behind" style trivial application into a full blown MVVM application? Or should I continue developing as I am and try to keep the unnecessary fluff out of the project?

• Dash search does not show applications

  - by To Do

  Since the upgrade (actually a fresh install) to 13.10, many times, when I open Dash and search for an application I only get results for files and folders. Sometimes I get some applications but not others. I haven't found a pattern to replicate the issue 100%. If I open the application lens and search again, it works as it should. So many times, to launch an application, I have to use the super + a key combination to open the application scope instead of the simply the super key. It is annoying. Did anyone have the same issue? I searched for bugs on launchpad but didn't find any. I didn't open a bug report yet because it is not clear how to reproduce the problem faithfully. Even more importantly, does anyone have a solution to this issue?

• Installing Silverlight applications without the browser involved

  One of the features we are introducing in Silverlight 4 is a silent install mechanism for out-of-browser applications. Currently every out-of-browser application (trusted or not) starts from an in-browser mechanism. In some instances where you want to deploy the app via managed desktop software or perhaps via CD-ROM, you dont want to have to tell the user to start on an HTML page first. Now Im not going to write here about the merits of why you might want to do this other than to point out what...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  ISV Engineering is happy to announce the release of the latest version of our Solaris Preflight Checker tool supporting Solaris 11.2. which is now available for download. The Solaris Preflight Checker enables a developer to determine the Oracle Solaris 11.2 readiness of an application by analyzing a working application on Oracle Solaris 10. A successful check with this tool will be a strong indicator that an application will run unmodified on the latest Oracle Solaris 11.This release includes: Updated symbol database which will help migration from Solaris 10 to Solaris 11.2 Kernel binary and source scanners that now detects, usage of "data structures" changed between Solaris 10 and Solaris 11.2 An application analyzer, which looks for usage of specific Solaris features and recommends better ways of implementing the same on Solaris 11.2   e.g. suitability of high performance libraries shipped with Solaris, crypto offload for Java & C based applications,  etc. And bug fixes

• SOLVED: Breaking parent web.config dependencies in sub applications

  This article explains how to implement a sub application such as a blog in your website without experiencing dependency issues. A common problem that developers experience is when their sub applications accidentally inherit requirements of the parent website. This is actually by design but read on if this is causing problems in your site. Scenario This problem has caught me out a couple of times so far but usually with enough of a gap between occurrences that it had become just a fuzzy memory....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Share laptop's Wi-Fi with a LAN connection and a mobile device

  - by xperator

  OS: Windows 7 64bit I want to share my laptop's internet connection between my PC and my Android device. But I can only do one of them at a time. The laptop is connected to internet wirelessly. The PC is connected to the laptop using a Ethernet cable and internet is shared between them. I want to connect my mobile device to my laptop by making the laptop into a Wi-Fi hotspot. PC (Ethernet) == Laptop (connected to net by Wi-Fi) <== Mobile device (Wi-Fi hotspot) I have 3 connections in my laptop: Wireless Network Connection (internet - shared) Local area connection (PC) Wireless Network Connection 2 (Wi-Fi hotspot) Every time I have to disable either the LAN to get the Wi-Fi hotspot working, or disable the Wi-Fi hotspot to get LAN working. How can I share so I can use both at the same time?

• Configure Apple Mobile Access Server for iPhones, iPads and Macs

  - by Studer

  I successfully configured Mobile Access Server on Mac OS X Server 10.6, but now, how do I configure Macs, iPhones and iPads I'm in charge of ? How can these machines access all the services provided by the Mobile Access Server ? I can't find anything useful on the web concerning the client setup. Is there any '1-click configuration' that would setup iCal, Addresses and Mail at once on a machine like the MobileMe setup does ? Or do I have to manually configure each services on each machines ? I gave a look at the iPhone Configuration Utility but it cannot configure Macs, obviously.

• Remote Desktop Mobile mangles barcodes coming from scanner

  - by sfonck

  Hi, We have an application here using handhelds to scan barcodes. These handhelds are actually making a remote desktop session towards a server where the application runs. Works fine. Now we have bought some new Motorola MC55's running 'Windows Mobile 6.1 Classic', and when using the application over remote desktop: it mangles the characters of the barcodes.... I already tried following things: When scanning a barcode on the MC55 itself it is displayed correctly When scanning a barcode via the remote desktop into a notepad session it is incorrect. Played with all options of the 'Remote Desktop Mobile' - no result Disabled 'autocorrect' and 'suggest words when entering text' on the input settings - no result The strange things is: a barcode which consists of only numbers gets scanned correctly the mangled characters comes through in lower case For some codes \t is mangled in between (should normally be entered after the barcode) e.g.: 'PERIN4' becomes 'ERINp4' 'MGZB' becomes 'GZB m' 'BAK664' becomes 'AK664 b' 'MAGBFA01' becomes 'AGBFmA01' '5021879949500' gets scanned correctly Anybody an idea how I could solve this problem?

• Windows Live Mail treating my Firefox as mobile device

  - by Mussnoon

  I started using Namoroka (firefox 3.6 nighly) yesterday and since then, windows live mail has been treating it like a mobile device. Same thing happens when I try with Minefield (firefox 4 nightly). I've tried loading the default page in Chromium and then pasting the URL to firefox. The sign in page shows alright then, but as soon as I sign in, the mobile inbox shows up again. I've tried clearing the cache+history+cookies everything but nothing's working. Anyone know of a solution?

• Mobile Intel® GMA 4500MHD boost

  - by Andy Smith

  My machine has a Mobile Intel® GMA 4500MHD integrated graphics chipset. The machine is currently running 64 bit windows 7 premium with 3GB of ram (1x1gb and 1x2gb). I note that the Mobile Intel® GMA 4500MHD shares the physical memory to process the graphics. now, the total available graphics memory can be up to 1,340 MB with a 32-bit operating system and 3 GB system memory or 1,759 MB with a 64-bit operating system and 4 GB system memory. I am considering investing in a 4GB stick to replace the 1gb stick bringing the total up to 6gb, mainly for an increase in graphics processing ability. Can anyone let me know what sort of power (if any over the 4gb) I could expect by upgrading to 6GB?

• Asterisk does not recognise DTMF tones from mobile phones

  - by Eugene van der Merwe

  We have an Asterisk 1.8.7.0 (the Elastix derivative) switchboard. Every since a month ago, seemingly out of the blue, the switchboard does not recognise DTMF tones any more from mobile phones. Testing the switchboard using 7777 works. Testing the switchboard from a normal phones works. Testing the switchboard from a mobile phone fails. Looking at the log file I can't see anything. I used 'asterisk -rvvvv' and 'tail -f /var/log/asterisk/full' to see the live output and scan the logs. I guess I don't see anything because it's simply not recognising the DTMF tones. I did brief research and found an old setting for SIP phones, 'rfc2833compensate=yes', and tried adding this to 'sip_general_custom.conf'. After that I did 'core restart when convenient' but that didn't make any difference. Could anyone give me some additional troubleshooting steps?

• Laptop loses signal from WiFi router, but mobile phone holds it fine

  - by Anton

  I have an extremely weird issue with my WiFi router. Both Ubuntu & Windows 7 can connect to it fine, but after 5-10 minutes browser (any one) stops opening pages and tells me it cannot resolve host address. But, at the same time, tools like Skype or BitTorrent work without any issues. I can also browse Internet on my mobile phone connected to the very same router. If I reset router it helps, but after 5-10 minutes I see just the same problem... Ubuntu tells me that WiFi signal is lost (mobile sees it), Windows 7 just won't let me browse anywhere. Can anyone give me a suggestion on this, please? Thanks
