• For structs, do I have to call the constructor explicitly in C#?

  - by Gulshan

  The question is about the structs. When I declare a struct type variable/object (don't know which one suits better) or an array or list of structs, do I have to call the constructor explicitly like objects or just declaring will suffice like variables?

• Is it true that the assigned final object field may still be null inside a constructor?

  - by Tom Brito

  Is it true that the assigned final object field may still be null inside a constructor? class MyClass { private final Object obj = new Object(); public MyClass() { System.out.println(obj); // may print null? } } if yes, isn't this a bug?

• In Scala, how does one write a class with a constructor, not all of whose arguments are class member

  - by user318816

  I want to write class whose constructor takes two parameters, but the arguments are not actually members of the class. e.g. class P(V1:Int, V2:Int) { val set = Set(V1, V2) } Having constructed the 'set', I don't actually care about V1 and V2. Is there a way of expressing this in Scala ?

• Passing parameter to base class constructor or using instance variable?

  - by deamon

  All classes derived from a certain base class have to define an attribute called "path". In the sense of duck typing I could rely upon definition in the subclasses: class Base: pass # no "path" variable here def Sub(Base): def __init__(self): self.path = "something/" Another possiblity would be to use the base class constructor: class Base: def __init__(self, path): self.path = path def Sub(Base): def __init__(self): super().__init__("something/") What would you prefer and why? Is there a better way?

• Can I refer to an object in its constructor?

  - by Roman

  Can I do the following? public Manager(String userName) { game = new Game(userName); game.addManager(this); } The problem is that I refer to an object (this) in its constructor (before it was actually created).

• Is it a good or bad practice to call instance methods from a java constructor?

  - by Steve

  There are several different ways I can initialize complex objects (with injected dependencies and required set-up of injected members), are all seem reasonable, but have various advantages and disadvantages. I'll give a concrete example: final class MyClass { private final Dependency dependency; @Inject public MyClass(Dependency dependency) { this.dependency = dependency; dependency.addHandler(new Handler() { @Override void handle(int foo) { MyClass.this.doSomething(foo); } }); doSomething(0); } private void doSomething(int foo) { dependency.doSomethingElse(foo+1); } } As you can see, the constructor does 3 things, including calling an instance method. I've been told that calling instance methods from a constructor is unsafe because it circumvents the compiler's checks for uninitialized members. I.e. I could have called doSomething(0) before setting this.dependency, which would have compiled but not worked. What is the best way to refactor this? Make doSomething static and pass in the dependency explicitly? In my actual case I have three instance methods and three member fields that all depend on one another, so this seems like a lot of extra boilerplate to make all three of these static. Move the addHandler and doSomething into an @Inject public void init() method. While use with Guice will be transparent, it requires any manual construction to be sure to call init() or else the object won't be fully-functional if someone forgets. Also, this exposes more of the API, both of which seem like bad ideas. Wrap a nested class to keep the dependency to make sure it behaves properly without exposing additional API:class DependencyManager { private final Dependency dependency; public DependecyManager(Dependency dependency) { ... } public doSomething(int foo) { ... } } @Inject public MyClass(Dependency dependency) { DependencyManager manager = new DependencyManager(dependency); manager.doSomething(0); } This pulls instance methods out of all constructors, but generates an extra layer of classes, and when I already had inner and anonymous classes (e.g. that handler) it can become confusing - when I tried this I was told to move the DependencyManager to a separate file, which is also distasteful because it's now multiple files to do a single thing. So what is the preferred way to deal with this sort of situation?

• Does binding temporary to a reference require a copy constructor in C++?

  - by vitaut

  Consider the following code: class A { A(const A&); public: A() {} }; int main() { const A &a = A(); } This code compiles fine with GCC, but fails to compile with Visual C++ with the following error: test.cc(8) : error C2248: 'A::A' : cannot access private member declared in class 'A' test.cc(2) : see declaration of 'A::A' test.cc(1) : see declaration of 'A' So is it necessary to have a copy constructor accessible when binding a temporary to a reference?

• How to find out which program a default beep is coming from in Windows 7?

  - by leeand00

  There's a "default beep" (as defined in System Sounds) that emanates from my computer every so often. It kind of goes like this (where each number is a "default beep" sound): 1, 2, 3, 4, 5. So there's a distinct pattern to it. I thought I had this figured out a way to figure out what was happening by going to Control Panel-Ease of Access-Ease of Access Center-Replace sounds with visual cues But that just isn't the case. Whichever window I click on, that one displays the visual queue when this happens. It's driving me crazy, and I can't figure out which program is causing this. Update: it appears to only happen on one user profile on the computer...does that help? Update 2: Discovered that this sound was coming from a utility on my laptop called ASUS NB Probe; I'm certain that it is emanating from this program because the error message displayed by it changes in sync with the sound playing. Apparently the S.M.A.R.T. feature of my hard drive was reporting an issue. It displays the issue for a brief second and then makes it disappear, I'll have to keep watching it to see what it says, but I believe is says something about a read. I have an external hdd connected with eSATA to a container of sorts (BlacX) that you can plug two hdds into. I have one hdd attached and it's a Western Digital WD1001FALS - 00E8B0 Thanks again! Now I'm off to go around the Internet and report on this...since I posted it so many places!

• How To Restore Firefox Options To Default Without Uninstalling

  - by Gopinath

  Firefox plugins are awesome and they are the pillars for the huge success of Firefox browser. Plugins vary from simple ones like changing color scheme of the browser to powerful ones likes changing the behavior of the browser itself. Recently I installed one of the powerful Firefox plugins and played around to tweak the behavior of the browser. At the end of my half an hour play, Firefox has completely become useless and stopped rending web pages properly. To continue using Firefox I had to restore it to default settings. But I don’t like to uninstall and then install it again as it’s a time consuming process and also I’ll loose all the plugins I’m using. How did I restore the default settings in a single click? Default Settings Restore Through Safe Mode Options It’s very easy to restore default settings of Firefox with the safe mode options. All we need to do is 1.  Close all the Firefox browser windows that are open 2. Launch Firefox in safe mode 3. Choose the option Reset all user preferences to Firefox defaults 4. Click on Make Changes and Restart button. Note: When Firefox restore the default settings, it erases all the stored passwords, browser history and other settings you have done. That’s all. This excellent feature of Firefox saved me from great pain and hope it’s going to help you too. Join us on Facebook to read all our stories right inside your Facebook news feed.

• Customize the Default Screensavers in Windows 7 and Vista

  - by Matthew Guay

  Windows 7 and Vista include a nice set of backgrounds, but unfortunately most of them aren’t configurable by default.  Thanks to a free app and some registry changes, however, you can make the default screensavers uniquely yours! Customize the default screensavers If you’ve ever pressed the Customize button on most of the default screensavers in Windows 7 and Vista, you were probably greeted with this message: A little digging in the registry shows that this isn’t fully correct.  The default screensavers in Vista and 7 do have options you can set, but they’re not obvious.  With the help of an app or some registry tips, you can easily customize the screensavers to be uniquely yours.  Here’s how you can do it with an app or in the registry. Customize Windows Screensavers with System Screensavers Tweaker Download the System Screensavers Tweaker (link below), and unzip the folder.  Run nt6srccfg.exe in the folder to tweak your screensavers.  This application lets you tweak the screensavers’ registry settings graphically, and it works great in all editions of Windows Vista and 7, including x64 versions. Change any of the settings you want in the screensaver tweaker, and click Apply. To preview the changes to your screensaver, open the Screen Saver settings window as normal by right-clicking on the desktop, and selecting Personalize. Click on the Screensaver button on the bottom right. Now, select your modified screensaver, and click Preview to see your changes. You can change a wide variety of settings for the Bubbles, Ribbons, and Mystify screensavers in Windows 7 and Vista, as well as the Aurora screensaver in Windows Vista.  The tweaks to the Bubbles screensaver are especially nice.  Here’s how the Bubbles look without transparency. And, by tweaking a little more, you get a screensaver that looks more like a screen full of marbles. Ribbons and Mystify each have less settings, but still can produce some unique effects.   How’s that for a brilliant screensaver? And, if you want to return your screensavers to their default settings, simply run the System Screensavers Tweaker and select Reset to defaults on any screensaver you wish to reset. Customize Windows Screensavers in the Registry If you prefer to roll up your sleeves and tweak Windows under-the-hood, then here’s how you can customize the screensavers yourself in the Registry.  Type regedit into the search box in the Start menu, browse to the key for each screensaver, and add or modify the DWORD values listed for that screensaver using the Decimal base. Please Note: Tweaking the Registry can be difficult, so if you’re unsure, just use the tweaking application above. Also, you’ll probably want to create a System Restore Point.   Bubbles To edit the Bubbles screensaver, browse to the following in regedit: HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Screensavers\Bubbles Now, add or modify the following DWORD values to tweak the screensaver: MaterialGlass – enter 0 for solid or 1 for transparent bubbles Radius – enter a number between 1090000000 and 1130000000; the larger the number, the larger the bubbles’ radius ShowBubbles – enter 0 to show a black background or 1 to show the current desktop behind the bubbles ShowShadows – enter 0 for no shadow or 1 for shadows behind the bubbles SphereDensity – enter a number from 1000000000 to 2100000000; the higher the number, the more bubbles on the screen. TurbulenceNumOctaves – enter a number from 1 to 255; the higher the number, the faster the bubble colors will change. Ribbons To edit the Ribbons screensaver, browse to the following in regedit: HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Screensavers\Ribbons Now, add or modify the following DWORD values to tweak the screensaver: Blur – enter 0 to prevent ribbons from fading, or 1 to have them fade away after a few moments. Numribbons – enter a number from 1 to 100; the higher the number, the more ribbons on the screen. RibbonWidth – enter a number from 1000000000 to 1080000000; the higher the number, the thicker the ribbons. Mystify To edit the Mystify screensaver, browse to the following in regedit: HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Screensavers\Mystify Now, add or modify the following DWORD values to tweak the screensaver: Blur – enter 0 to prevent lines from fading, or 1 to have them fade away after a few moments. LineWidth – enter a number from 1000000000 to 1080000000; the higher the number, the wider the lines. NumLines – enter a number from 1 to 100; the higher the value, the more lines on the screen. Aurora – Windows Vista only To edit the Aurora screensaver in Windows Vista, browse to the following in regedit: HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Screensavers\Aurora Now, add or modify the following DWORD values to tweak the screensaver: Amplitude – enter a value from 500000000 to 2000000000; the higher the value, the slower the motion. Brightness – enter a value from 1000000000 to 1050000000; the higher the value, the brighter the affect. NumLayers – enter a value from 1 to 15; the higher the value, the more aurora layers displayed. Speed – enter a value from 1000000000 to 2100000000; the higher the value, the faster the cycling. Conclusion Although the default screensavers are nice, they can be boring after awhile with their default settings.  But with these tweaks, you can create a variety of vibrant screensavers that should keep your desktop fresh and interesting.

• SharePoint 2010 Hosting :: Setting Default Column Values on a Folder Programmatically

  - by mbridge

  The reason I write this post today is because my initial searches on the Internet provided me with nothing on the topic.  I was hoping to find a reference to the SDK but I didn’t have any luck.  What I want to do is set a default column value on an existing folder so that new items in that folder automatically inherit that value.  It’s actually pretty easy to do once you know what the class is called in the API.  I did some digging and discovered that class is MetadataDefaults. It can be found in Microsoft.Office.DocumentManagement.dll.  Note: if you can’t find it in the GAC, this DLL is in the 14/CONFIG/BIN folder and not the 14/ISAPI folder.  Add a reference to this DLL in your project.  In my case, I am building a console application, but you might put this in an event receiver or workflow. In my example today, I have simple custom folder and document content types.  I have one shared site column called DocumentType.  I have a document library which each of these content types registered.  In my document library, I have a folder named Test and I want to set its default column values using code.  Here is what it looks like.  Start by getting a reference to the list in question.  This assumes you already have a SPWeb object.  In my case I have created it and it is called site. SPList customDocumentLibrary = site.Lists["CustomDocuments"]; You then pass the SPList object to the MetadataDefaults constructor. MetadataDefaults columnDefaults = new MetadataDefaults(customDocumentLibrary); Now I just need to get my SPFolder object in question and pass it to the meethod SetFieldDefault.  This takes a SPFolder object, a string with the name of the SPField to set the default on, and finally the value of the default (in my case “Memo”). SPFolder testFolder = customDocumentLibrary.RootFolder.SubFolders["Test"]; columnDefaults.SetFieldDefault(testFolder, "DocumentType", "Memo"); You can set multiple defaults here.  When you’re done, you will need to call .Update(). columnDefaults.Update(); Here is what it all looks like together. using (SPSite siteCollection = new SPSite("http://sp2010/sites/ECMSource")) {     using (SPWeb site = siteCollection.OpenWeb())     {         SPList customDocumentLibrary = site.Lists["CustomDocuments"];         MetadataDefaults columnDefaults = new MetadataDefaults(customDocumentLibrary);          SPFolder testFolder = customDocumentLibrary.RootFolder.SubFolders["Test"];         columnDefaults.SetFieldDefault(testFolder, "DocumentType", "Memo");         columnDefaults.Update();     } } You can verify that your property was set correctly on the Change Default Column Values page in your list This is something that I could see used a lot on an ItemEventReceiver attached to a folder to do metadata inheritance.  Whenever, the user changed the value of the folder’s property, you could have it update the default.  Your code might look something columnDefaults.SetFieldDefault(properties.ListItem.Folder, "MyField", properties.ListItem[" This is a great way to keep the child items updated any time the value a folder’s property changes.  I’m also wondering if this can be done via CAML.  I tried saving a site template, but after importing I got an error on the default values page.  I’ll keep looking and let you know what I find out.

• A Few Cool Things You Can Identify Using the Default Trace

  If you are running an instance of SQL Server 2005 and above then most likely that instance is running the default trace. This default trace is a canned Profiler server side trace that automatically starts up when SQL Server starts. In this article Greg Larsen explains more about the default trace and shows you how to glean some event information from the trace files created by this background trace process.

Basically I want to have 6 versions of the site: UK English US English Default English ?? Austrian German Germany German Default German The question is, how do I define the "default" language versions, for any country with this language which isnt defined already? I know there is x-default, but I think you can only use that once and it is for all languages and all countries.

• How to change default foreign language font

  - by preahkumpii

  I want to know how to change the default font that is used when inputting a particular language. I use the Khmer language frequently, and the default font installed comes from the fonts-khmeros-core package. The fonts are fine, except that there better fonts. Once I install my beloved font, how do I cause Ubuntu to use that font instead of the ones from the package? Additionally, if you remove the fonts-khmeros-core package, and have only the custom font installed, the custom font will not be used by default, even if no other Khmer fonts are installed. However, when you install that package, those fonts are immediately used by default. Any ideas? Thanks.

Since there is no "default" theme in 2010. So make sure if you wanna reset it to default you know that there is no default, you need to select 'none' :)

• Maintaining SQL Server default trace historical events for analysis and reporting

  I often see questions online where someone wants to find out who started a trace, when tempdb last had an autogrow event, or when the last full backup for master occurred. Since these and other events are captured by the default trace, but the default trace only keeps five 20MB rollover files by default. This means that the event you are after may no longer be there, depending on how long ago it was and how busy your server happens to be. Unfortunately, people often need to find this information well after the fact.
