  • Kill Android Apps without Task Manager

    - by Gopinath
    Android is for geeks. It best fits for the users who know how to get around sloppy areas and find their way out. If you are an heavy Android user you would have noticed Apps crashing often. A well written App should not crash, if crashes should exit the process gracefully. But unfortunately Google Play has many apps that not only just crash, they hang in a where they don’t respond and you can’t access the application. The only option left to you is to forcefully close them. If you encounter a situation to forcefully close an App you have two options. First one is to use Task Manager application to close them and the second option is use built in Android OS features. Here are the steps to forcefully close an Android App without using Task Manager Step 1: Go to Settings and select Apps Step 2: Switch to All apps tab and select the application you want to close Step 3: Touch on Force Stop button to forcefully close the app That’s the simplest way to forcefully kill Android Apps.

  • OK, I have my database ready, now what's missing?

    - by fatherjack
    During the life of any database there will be times when the development makes a change that breaks functionality of an object somewhere else in the database. SQL Server does a good job in some places of making this impossible, or at least really difficult, but in other places there isn't even a murmur as you execute a script that will bring your system processes out in a nasty plague of error messages. Where it works. If you try to create a view based on a table or column that doesn't...(read more)

  • How to shutdown Windows 8 PC without using mouse?

    - by Gopinath
    Windows 8 sports a re-imagined desktop and tablet user interface with touch friendly Metro looks. One of the major changes in Windows 8 for a common users  is the lack of start menu, with which we got friended for more than a decade. On Windows 8 we would be missing it. As there is no start menu in Windows 8, the way you shutdown a Windows 8 computer is a bit different. To shutdown using Mouse, you need to hover on the top right edge of the screen to open the hidden menu,  go to "Settings"  tab -> "Power" -> Then choose for "Shut down", "Sleep" or "Restart".  That’s a lot of Mouse movement work and if you are a power user then you may not like to do that. How about shutting down the PC using Keyboard? Here are the two ways to shutdown the PC using keyboard Keyboard shortcuts With the help of keyboard shortcuts you can navigate to Power options of Windows 8. Press Win + C to bring the Settings Charm and use Arrows and Enter keys to navigate to access Shutdown menu. This is one of the easiest way to shutdown the PC without using Mouse. Run Command If you don’t like to go through the Setting menu, you can use the traditional Run commands. Press Win + R to open Run dialog and enter the command shutdown -s -t 0 to immediately shutdown the PC.

  • Start a new project. Where is the inspiration ?

    - by Kakawait
    The question may seem strange at first glance ... And I may be alone in this situation. But currently I want to improve my skill through learning new framework. however, do a simple "HelloWorld" application does not satisfy me. I think a practical project is required to apprehend the basics of a framework. I know there is many scholar-like project like design a library manager or CMS. But I have recently planned to learn ~3 differents frameworks and I can't find any motivations through "unexciting" project. In the end I have not started any framework ... I'm aware of I do not develop the project of the year ... I'm just looking for something a bit exciting. I do not expect any project subject, anyway stimulation provided by a project is something subjective. But I want to know your inspiration ! (or method to learn framework ^^) I'm talking about web-dev framework but I'm open to any kind information ! Kind regards.

  • Html.ValidationSummary and Multiple Forms

    - by MightyZot
    Originally posted on: http://geekswithblogs.net/MightyZot/archive/2013/11/11/html.validationsummary-and-multiple-forms.aspxThe Html.ValidationSummary helper writes a div with a list of general errors added to the model state while a request is being serviced. There is generally one form per view or partial view, I think, so often there is only one call to Html.ValidationSummary in the page resulting from the assembly of your views. And, consequently, there is no problem with the markup that Html.ValidationSummary spits out as a result. What if you want to put multiple forms in one view? Even if you create a view model that’s an aggregate of the view models for each form, the error validation summary is going to contain errors from both forms. Check out this screen shot, which shows a page with multiple forms. Notice how the error validation summary shows up twice. Grrr! Errors for the login form also show up in the registration form. Luckily, there is an easy way around this. Pull the errors out of the model state and separate them for each form. You’ll need to identify the appropriate form by setting the key when you make calls to ModelState.AddModelError. Assume in my example that errors for the login form are added to model state using the “LoginForm” key. And, likewise, assume that errors for the registration form are added to model state using the “RegistrationForm” key. An example of that might look like this… // If we got this far, something failed, redisplay form ModelState.AddModelError("LoginForm", "User name or password is not right..."); return View(model); Over in the code for your View, you can pull each form’s errors from the model state using lambda expressions that look like these… var LoginFormErrors = ViewData.ModelState.Where(ms => ms.Key == "LoginForm"); var RegistrationFormErrors = ViewData.ModelState.Where(ms => ms.Key == "RegistrationForm"); Now that you have two collections containing errors, you can display only the errors specific to each form. I’m doing that in my code by removing the calls to Html.ValidationSummary and replacing them with enumerators that look like this… if(LoginFormErrors.Count() > 0) { <div class="cdt-error-list">     <ul>     @foreach (var entry in LoginFormErrors)     {         foreach (var error in entry.Value.Errors)         {             <li>@error.ErrorMessage</li>         }     }     </ul> </div> } …and for the registration form, the code looks like this… @if(RegistrationFormErrors.Count() > 0) { <div class="cdt-error-list">     <ul>     @foreach (var entry in RegistrationFormErrors)     {         foreach (var error in entry.Value.Errors)         {             <li>@error.ErrorMessage</li>         }     }     </ul> </div> } The result is a nice clean separation of the list of errors that are specific to each form. And, this is important because each form is submitted separately in my case, so both forms don’t generate errors in the same context. As you’ll see in the screen shot below, errors added to the model state when the login form is submitted do not show up in the registration form’s validation summary.

  • Jobs - are your SQL Agent jobs talking to you enough?

  • How To Delete Your Skype Call and Chat History

    - by Gopinath
    Just like every other modern application, Skype also records all the communications we exchange using it. It records instant messages, calls, file transfers, SMS, etc. and makes it easy to view using the Conversation tab. If you ever feel like getting rid of these history information, then you need to delete them. Skype provides a single click option to clear all the history from you account, but the feature is buried deep under options menu.Really deep!. To clear history follow the menu Tools –> Options, switch to Privacy Settings tab available on the left side, click on Show advanced options button and finally hit the button Clear history. Ah! You are almost done. Just confirm a popup it displays on screen and your history is vanished from your account. Join us on Facebook to read all our stories right inside your Facebook news feed.

  • Alerts are good, aren't they?

    - by fatherjack
    It is accepted best practise to set some alerts on every SQL instance you install. They aren't particularly well publicised but I have never seen any one not recommend setting up alerts for Error 823, 824 and 825. These alerts are focussed on successful access(IO) to the hard drives that SQL Server is using. If there are  any errors when reading or writing to the drives then one of these errors will be returned. Having the alerts on these errors means that any IO issues will be brought to the...(read more)

  • How to enable Start Button in Windows 8?

    - by Gopinath
    Microsoft taken a bold move in removing Start button in Windows 8 operating system and replacing it with Metro styled Start screen. Since the early days of Microsoft Windows, all the PC users are used to Start button and missing it all of sudden in Windows 8 may disappointed many. If you are one among the users who is disappointed with missing Windows 8 button, here is a quick way to enable it back To restore Start menu in Windows 8 all you have to do is to download and install ViStart application. This freeware application magically brings back the missing Start orbit and also when you press Windows Key, it opens up the Start menu instead of switching to Windows 8 Start Screen. Note: While installation the application may ask you to install toolbars and third party application, I suggest you to uncheck them as they may change your search settings and default browser.  They may not be harmful but effects your browsing experience.

  • How to stop Office 2010 changing " and ' to smart quotes

    - by fatherjack
    I have recently upgraded to Office 2010 at work and there are a few things that are a real problem for me. As a T-SQL developer and SQL Server DBA I copy and paste code to and from various applications and if Word gets involved it can has disastrous consequences. There is an option that appears to be defaulted to "on" that changes a straight quote to what Word describes as a smart quote - see the image below. Note - the single quote suffers from the same effect. Now, getting to the point that...(read more)

  • Make your TSQL easier to read during a presentation

    - by fatherjack
    SQL Server Management Studio 2012 has some neat settings that you can use to help your presentations at a SQL event better for the attendees if you are willing to spend a few minutes making some settings changes. Historically, I have been reluctant to make changes to my SSMS settings as it is such a tedious process and it's not 100% clear that what you think you are changing is actually what gets changed. With SSMS 2012 this has become a lot easier and a...(read more)

  • What are the core mathematical concepts a good developer should know?

    - by Jose B.
    Since Graduating from a very small school in 2006 with a badly shaped & outdated program (I'm a foreigner & didn't know any better school at the time) I've come to realize that I missed a lot of basic concepts from a mathematical & software perspective that are mostly the foundations of other higher concepts. I.e. I tried to listen/watch the open courseware from MIT on Introduction to Algorithms but quickly realized I was missing several mathematical concepts to better understand the course. So what are the core mathematical concepts a good software engineer should know? And what are the possible books/sites you will recommend me?

  • What are some cool git or .gitignore tricks & best practices? [closed]

    - by 01walid
    Git is just awesome and fast VCS, however, knowing better this tool will help you incredibly increase your productivity and save your time. Here we can try to make a collection of tips, tricks and useful links to better take advantage of git, this question can have some more sub-questions, I mean: what are some usefull commands that reverse or rectify commits/adding/removing mistakes? what are .gitignore & Global .gitignore best practices? especially with private/secure files that contains passwords, api keys, local config and so on ... .gitignore first or git add <files> first? what are the advantages/disadvantages of both being the first/last. links to blog post, articles, would be sufficient. I thought every sub-question is not worthy opening a whole post each alone, I think centralizing these tips in one question post would help many people.

  • Any tips/tricks/resources on actually TEACHING a class on OOP? [closed]

    - by Sempus
    I may slowly be getting into teaching an Object-Orientated Programming class at my school in a year or two. I just graduated and work at my school as an Application Programmer. I'd first start off as a TA/grader and then slowly move into the Professor role. The class would be in Java. I always see resources on this fine site about HOW to program, but does anyone know any tips/tricks/resources on how to TEACH a programming class? It would be full of all different skills levels(but still semi-technical) so it would have to be a little more understandable than if it was just CS kids.

  • The Coolest Parts of Windows API

    - by Andreas Rejbrand
    I have noticed that there are quite a few community wikis about "Tips & Tricks" or "Hidden Features" in programming languages and APIs here at Stack Overflow. But I could not find any about my own personal favourites: Win32 API and Delphi. Therefore I start my "own" CW about Win32 API. There are (at least) two kinds of Win API users: those that have been brought up using Windows API in C/C++, and those that have been brought up using some level of abstraction above the Windows API. I belong to the latter category, being brought up using Delphi's VCL. But over the last five years, I have become increasingly interested in the underlaying API of the Windows operating system, and today I work a lot with it. Depending on which category a programmer belongs to, he (or possibly she) will think that different things are "cool" in the Windows API. For instance, whereas a VCL-brought up developer might think it it very cool to var errIcon: HICON; begin errIcon := LoadIcon(0, IDI_ERROR); DrawIcon(Canvas.Handle, 10, 10, errIcon), a programmer brought up using Windows API in C will not be as impressed. But no matter how you are "brought up": what are the coolest "tricks" in Windows API? I start by listing a few of my own favourites, some of which are more "cool" than "useful", though: LoadIcon and MessageBeep can load/play system default icons and sounds. Open the CD tray: mciSendString('Set cdaudio door open wait', nil, 0, 0); Fade out the screen (Windows Vista and later) and turn of the monitor: SendMessage(Application.Handle, WM_SYSCOMMAND, SC_MONITORPOWER, 2); GetWindowDC(GetDesktopWindow) returns the DC of the desktop.

  • Dijkstra’s algorithm and functions

    - by baris_a
    Hi guys, the question is: suppose I have an input function like sin(2-cos(3*A/B)^2.5)+0.756*(C*D+3-B) specified with a BNF, I will parse input using recursive descent algorithm, and then how can I use or change Dijkstra’s algorithm to handle this given function? After parsing this input function, I need to execute it with variable inputs, where Dijkstra’s algorithm should do the work. Thanks in advance. EDIT: May be I should ask also: What is the best practice or data structure to represent given function?
