  • Disposable Registry: good pattern?

    - by illdev
    Imagine a: public class Global : IDisposable { private static readonly List<IDisposable> Disposables = new List<IDisposable>(); public void ApplicationStart() { var heavyLifter = new HeavyLifter(); Disposables.Add(heavyLifter); } public void Dispose() { Disposables.ForEach(d => d.Dispose()); } } I am somewhat inexperienced with IDisposable. Is this a viable pattern?

  • How to set a keybinding which is valid in all modes in Emacs

    - by AnotherEmacsLearner
    Hi, I've configured my emacs to use M-j as backward-char by (global-set-key (kbd "M-j") 'backward-char) ; was indent-new-comment-line in my .emacs file. This works fine in many modes (text/org/lisp). But in c++-mode & php-mode it is bound to the default c-indent-new-comment-line How can I bind M-j to use backward-char in these modes too. And in general for ALL modes. Thanks, AnotherEmacsLearner

  • How can I tweak this elisp function to distinguish between C-d & DEL?

    - by Fletcher Moore
    Here's my current function (blindly copy-pasted from a website) (defun tweakemacs-delete-one-line () "Delete current line." (interactive) (beginning-of-line) (kill-line) (kill-line)) (global-set-key (kbd "C-d") 'tweakemacs-delete-one-line) There are two quirks here that I want to get rid of. 1) This actually rebinds DEL to the same function. I want my DEL to remain "delete one character". 2) There needs to be a condition where it will not double-kill if the line is only a newline character.

  • Changing tabs in android

    - by Pavel
    Hi guys. Can someone please tell me how to change tab by clicking on element INSIDE the tab? I already tried it with global data. The code looks like this: public class Tabs extends TabActivity { int tabNumber = 0; private TabHost tabHost; int returnedTabNumber = 0; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); // Resource object to get Drawables tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Resusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, Tribocracy.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("map").setIndicator("Map", res.getDrawable(R.drawable.ic_tab_artists)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, Areas.class); spec = tabHost.newTabSpec("areas").setIndicator("Areas", res.getDrawable(R.drawable.ic_tab_albums)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, Settings.class); spec = tabHost.newTabSpec("settings").setIndicator("Settings", res.getDrawable(R.drawable.ic_tab_albums)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTab(tabNumber); } protected void onResume() { super.onResume(); GlobalData globalData = ((GlobalData)getApplicationContext()); returnedTabNumber = globalData.getTabNumber(); tabHost.setCurrentTab(returnedTabNumber); } } The global adapter looks like this: public class GlobalData extends Application { //---------------------------------------------------- private int Point1; //define the vars here private int Point2; //define the vars here private int Point3; //define the vars here private int Point4; //define the vars here private int Point5; //define the vars here private int Point6; //define the vars here private int tabNumber; public int getTabNumber() //getter of the value { return tabNumber; } public int setTabNumber(int number) //setter of the value { tabNumber = number; return tabNumber; } } Now when I'm trying to change tab in my ListActivity tab by clicking on one of the items it doesn't do anything and stays on the ListActivity tab. Perhaps I shouldn't use onResume() here. Basically I want to go to first tab when I click on one of the items in the list. Please help!

  • IIS7 Itegrated Pipeline Mode: Context.User is intermittently null for Windows Auth

    - by AndyV
    Our code relies on checking the Context.User.Identity value in the Global.asax Application_AuthenticateRequest(...) method to retrieve some information about the logged in user. This works fine in classic mode but when I flip IIS to use the Integrated Pipeline "Context.User" comes back as null, but only intermittently. Any ideas why? I have < authentication mode="Windows" and only Windows Auth enabled in the Virtual Directory.

  • ASP.NET MVC Default URL View

    - by Moose Factory
    I'm trying to set the Default URL of my MVC application to a view within an area of my application. The area is called "Common", the controller "Home" and the view "Index". I've tried setting the defaultUrl in the forms section of web.config to "~/Common/Home/Index" with no success. I've also tried mapping a new route in global.asax, thus: routes.MapRoute( "Area", "{area}/{controller}/{action}/{id}", new { area = "Common", controller = "Home", action = "Index", id = "" } ); Again, to no avail.

  • Adding Items to an Inner (Nested) ListView

    - by Corey O.
    I have 2 asp:ListView controls, one embedded in the other (OuterListView and InnerListView respectively). I am trying to add an asp:linkbutton in the InnerListView layout that will allow the user to add an item to the InnerListView. Unfortunately, when I handle the OnClick event in the linkbutton control, I can't figure out how to get a handle on the asp:linkbutton's parent ListView from within the codebehind handler. Obviously, there is no global handle since there are multiple inner listviews. I can link code if necessary.

  • How do I do distributed UML development (à la FOSS)?

    - by James A. Rosen
    I have a UML project (built in IBM's Rational System Architect/Modeler, so stored in their XML format) that has grown quite large. Additionally, it now contains several pieces that other groups would like to re-use. I come from a software development (especially FOSS) background, and am trying to understand how to use that as an analogy here. The problem I am grappling with is similar to the Fragile Base Class problem. Let me start with how it works in an object-oriented (say, Java or Ruby) FOSS ecosystem: Group 1 publishes some "core" package, say "net/smtp version 1.0" Group 2 includes Group 1's net/smtp 1.0 package in the vendor library of their software project At some point, Group 1 creates a new 2.0 branch of net/smtp that breaks backwards compatibility (say, it removes an old class or method, or moves a class from one package to another). They tell users of the 1.0 version that it will be deprecated in one year. Group 2, when they have the time, updates to net/smtp 2.0. When they drop in the new package, their compiler (or test suite, for Ruby) tells them about the incompatibility. They do have to make some manual changes, but all of the changes are in the code, in plain text, a medium with which they are quite familiar. Plus, they can often use their IDE's (or text editor's) "global-search-and-replace" function once they figure out what the fixes are. When we try to apply this model to UML in RSA, we run into some problems. RSA supports some fairly powerful refactorings, but they seem to only work if you have write access to all of the pieces. If I rename a class in one package, RSA can rename the references, but only at the same time. It's very difficult to look at the underlying source (the XML) and figure out what's broken. To fix such a problem in the RSA editor itself means tons of clicking on things -- there is no good equivalent of "global-search-and-replace," at least not after an incomplete refactor. They real sticking point seems to be that RSA assumes that you want to do all your editing using their GUI, but that makes certain operations prohibitively difficult. Does anyone have examples of open-source UML projects that have overcome this problem? What strategies do they use for communicating changes?

  • Extending Eclipse product (parallel developments on a set of codes)

    - by zeroin23
    A spawn off of an existing eclipse product is required for customization for a client. (hence parallel product development) The intention was to use Eclipse Fragment, but "Fragments are additive, they cannot override content found in the host." how can we maintain one set of codes in the svn, yet allow customization by overriding some classes? the current solution is to have a global flag to indicated which product it is and "if" "else" littered everywhere in the codes ...

  • Custom membership provider via WCF authorization question

    - by Diego
    I've made a global authentication via WCF to use with the most of our systems, but found that load data via WCF not very so fast. What I need to do now is verify every time that the page is loading if the user has access granted to that page.... Its a good pratice to go back in WCF request this info for every page that the user access?This will not slow down my entire system?

  • Conditional skin file in ASP.Net Theme based off of browser

    - by Dan Appleyard
    Is there a way to use a skin file in a theme only when a certain browser is used? The theme stays the same, I just want skin A to apply when a certain browser is used, and skin B when another browser is used. I know I can have server-side code to check and then set the SkinId of the control to either or, but is there another, more global way? Thanks
