  • Problem with default File opening programs

    - by Rahul
    Working on Vista & Window 7, I use Winamp 5.57 for listening to mp3 and VLC player for watching movies. I made those two as my default players for corresponding media respectively. But when I launch winamp for playing mp3, some of the video files( like .flv, etc.,) automatically get changed the file opening mode to winamp player. This happens every time even if I set it back to 'default program'. Can someone please help me out.

  • Reinstalling Default Website for Exchange 2010

    - by Michael
    The Default Website for Exchange 2010 on Windows SBS Server 2010 has been deleted (how and why is not important). Now, obviously, I cant access emails via OWA or via HTTP for people offsite. I can not figure out how to reinstall the default website to reinstall OWA and settings? I also can't log into Exchange Mangement Console. The attempt to connect to... using "kerberos" jauthenication failed (probably because it does not exist).

  • Changing default playback device on Windows 8

    - by emartel
    Previously, on Vista and Windows 7, changing the Default Playback device would occur instantly. For example, audio is coming out of my speakers, I right click the Volume Control, click Playback Devices then I select another device and click Set Default. Audio would be transferred immediately. Unfortunately, now, with Windows 8, I need to kill whatever process what outputting sound, and restart it for the change to take effect. Is there something that can be done about it so that changes are taken into account immediately?

  • How to change default user (ubuntu) via CloudInit on AWS

    - by Gui Ambros
    I'm using CloudInit to automate the startup of my instances on AWS. I followed the (scarce) documentation available at http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/annotate/head%3A/doc/examples/cloud-config.txt and examples on /usr/share/doc/cloud-init, but still haven't figured out how to change the default username (ubuntu, id:1000). I know I can create a script to manually delete the default ubuntu and add my user, but seems counter intuitive given that CloudInit exist exactly to automate the initial setup. Any ideas?

  • Mixing AJAX requests with Flash scope objects not working

    - by AlanObject
    I have a JSF page that displays a table from an object called TableQuery that supports stateful pagination, sorting, etc. The bean that accesses the object is a RequestScoped object, and it attempts to preserve the TableQuery by storing it the flash map. The accessor method looks like this: public TableQuery<SysLog> getQuery() { if (query != null) return query; Flash flash = FacesContext.getCurrentInstance(). getExternalContext().getFlash(); query = (TableQuery) flash.get("Query"); if (query != null) System.out.println("TableSysLog.getQuery() Got query from flash!"); if (query == null) { query = slc.getNewTableQuery(); System.out.println("TableSysLog.getQuery() Created new query"); } flash.put("Query", query); return query; } The Links to go between pages are implemented with *p:commandLInk*s. I use Primefaces command link in AJAX mode so just the link gets processed when it is clicked. The action listener looks like this: public void doNextPage(ActionEvent evt) { getQuery().doNextPage(); } When it doesn't work I get the error message: WARNING: JSF1095: The response was already committed by the time we tried to set the outgoing cookie for the flash. Any values stored to the flash will not be available on the next request. I found this thread when looking up this problem. When I turned of HTTP chunking as the article suggests, the error message went away but the problem remained. Does anyone know what is going on and how this might be fixed?

  • Scope of StaticResource within a WPF ResourceDictionary

    - by Nicolas Webb
    I have a WPF ResourceDictionary with the following TextBlock: <TextBlock Visibility="{Binding Converter={StaticResource MyBoolProp ResourceKey=BoolToVis}}"> </TextBlock> The ResourceDictionary is included in App.xaml under MergedDictionaries: <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="MyResourceDictionary.xaml"/> Within the App.xaml I have defined the BoolToVis converter (again, under Application.Resources) <BooleanToVisibilityConverter x:Key="BoolToVis" /> When I start my app up - I get the following XamlParseException: "Provide value on 'System.Windows.Markup.StaticResourceHolder' threw an exception." The InnerException is: "Cannot find resource named 'BoolToVis'. Resource names are case sensitive." I'm able to refer to this converter directly with App.xaml (in fact, it's another TextBlock) and within other UserControls with no problems. This particular bit of code also worked fine under the .NET 4.0 RC (and Beta2). This error only started happening when I upgraded to the .NET 4.0 RTM. I'm able to work around it by declaring another BooleanToVisibilityConverter within MyResourceDictionary.xaml and referring to it like so: <TextBlock Visibility="{Binding Converter={StaticResource MyBoolProp ResourceKey=BoolToVis2}}"> </TextBlock> Any reason why I should need to do this?

  • the scope of a pointer ???

    - by numerical25
    Ok, so I did find some questions that were almost similar but they actually confused me even more about pointers. http://stackoverflow.com/questions/2715198/c-pointer-objects-vs-non-pointer-objects-closed In the link above, they say that if you declare a pointer it is actually saved on the heap and not on the stack, regardless of where it was declared at. Is this true ?? Or am I misunderstanding ??? I thought that regardless of a pointer or non pointer, if its a global variable, it lives as long as the application. If its a local variable or declared within a loop or function, its life is only as long as the code within it.

    - by James Santiago
    I want to initiate a class for each user at the start of the user's session so that a single class can be used throughout the user's session. I checked out this post but I'm not sure where I should be placing this Sessionhandler class. Inside global.asax? How do I go about accomplishing this?

  • Scope of Connection Object for a Website using Connection Pooling (Local or Instance)

    - by Danny
    For a web application with connection polling enabled, is it better to work with a locally scoped connection object or instance scoped connection object. I know there is probably not a big performance improvement between the two (because of the pooling) but would you say that one follows a better pattern than the other. Thanks ;) public class MyServlet extends HttpServlet { DataSource ds; public void init() throws ServletException { ds = (DataSource) getServletContext().getAttribute("DBCPool"); } protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { SomeWork("SELECT * FROM A"); SomeWork("SELECT * FROM B"); } void SomeWork(String sql) { Connection conn = null; try { conn = ds.getConnection(); // execute some sql ..... } finally { if(conn != null) { conn.close(); // return to pool } } } } Or public class MyServlet extends HttpServlet { DataSource ds; Connection conn;* public void init() throws ServletException { ds = (DataSource) getServletContext().getAttribute("DBCPool"); } protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { try { conn = ds.getConnection(); SomeWork("SELECT * FROM A"); SomeWork("SELECT * FROM B"); } finally { if(conn != null) { conn.close(); // return to pool } } } void SomeWork(String sql) { // execute some sql ..... } }

  • What is the scope of xsl apply-imports?

    - by calavera.info
    My original idea about apply-imports was that if there are two templates which matches the same node, then using apply-imports in a template with higher priority runs the template with the lower priority. But I recently find out that it's important how are imports organized. Two cases interests me particularly. Will apply imports work on a template which is imported in imported file (nested import)? How about a "sibling import" (master file imports two files with templates matching the same nodes) It seems to me that this is not clearly described in specification. Could someone provide authoritative guidelines? EDIT: I can try those cases on my own, but there is always a danger that it will be implementation specific behavior.

  • C stack/scope, variable's lifetime after functions ends

    - by Ranking Stackingblocks
    void someFunc() { int stackInt = 4; someOtherFunc(&stackInt); } Is it the case that stackInt's address space could be reallocated after someFunc ends, making it unsafe to assume that the value passed to someOtherFunc represents the stackInt variable with value 4 that was passed to it? In other words, should I avoid passing stack variables around by address and expecting them to still be alive after the function they were initialised in has ended?

  • Javascript Array Scope - newbie here

    - by Gianluca
    So, I am learning Javascript while playing white Google Calendar APIs and I just can't figure how this piece of code is working this way: var entriesResult = []; var data = new Date(2010,3,22,17,0,0); var callback = function(result) { var entries = result.feed.getEntries(); if (entries.length != 0) { entriesResult = eventsManager(entries, 0, data); window.alert("inner entriesResult " + entriesResult.length); } } this.service.getEventsFeed(this.query, callback, handleGDError); window.alert("outer entriesResult " + entriesResult.length); eventsManager() is a function that returns an array of Objects. getEventsFeed() it's an API function: it queries the service and pass a "feed root" (a feed with selected items) to the callback function. Why the first alert (inner..) outputs a valid entriesResult.length while the second one (outer..) always outputs a 0? I tought javascript arrays are always passed by reference, what's wrong whit my code? Thank you :)

  • TWiki: Restricting users scope of editing the pages.

    - by abhishekgupta92
    I am making a twiki website and I am stuck with a problem. The users have access to write the files. So, I want to include Report Abuse option so that in case of vandalism of someone the thing can be corrected as soon as possible. Also, I am facing one more problem that someone told me that while editing the code the person can change the read/write permissions for the other users. And obviously, that wouldn't be something that I am expecting from Twiki. C'mon there must be some way of moderation in twiki to ensure thatthere is no undesirable content.

  • WPF not applying default styles defined in MergedDictionaries?

    - by Burgberger
    In a WPF application I defined default control styles in separate resource dictionaries (e.g. "ButtonStyle.xaml"), and added them as merged dictionaries to a resource dictionary named "ResDictionary.xaml". If I refer this "ResDictionary.xaml" as merged dictionary in my App.xaml, the default styles are not applied. However, if I refer the "ButtonStyle.xaml", it works correctly. If I recompile the same code in .NET 3.5 or 3.0, it recognizes and applies the default styles referred in "App.xaml" through "ResDictionary.xaml", but not in .NET 4.0. At runtime if I check the Application.Current.Resources dictionary, the default styles are there, but they are not applied, only if I specify the Style property explicitly in the Button control. Are there any solutions to refer a resource dictionary (containig default styles) this way in .NET 4.0? App.xaml: <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Styles/ResDictionary.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> ResDictionary.xaml: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Default/ButtonStyle.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> ButtonStyle.xaml: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Style TargetType="Button"> <Setter Property="Background" Value="Yellow"/> </Style> </ResourceDictionary>

  • jQuery - ajax page load - php scope

    - by Develman
    I am using jquery.tabs() and want to load the pages of the tabs with ajax. I am using MVC pattern with PHP and used a frontcontroller / pagecontroller pattern. The templating is done by PHP, e.g.: <?php if($this->userLoggedIn == TRUE): ?> <span>Herzlich Willkommen <?php echo $this->userName; ?>! [<a href="logout">Ausloggen</a>] </span> <?php endif; ?> The variables ($this-userName) are injected by the pagecontroller class. The problem is, that when I load a page via ajax, the variables are not known. Following PHP error is coming up: Fatal error: Using $this when not in object context.... Any idea, how to use / load the variables and using it in the template files.

  • Next, Previous Records Using Named Scope

    - by keruilin
    I have a model for which I want to retrieve the next record(s) and previous record(s). I want to do this via a named_scope on the model, and also pass in as an argument the X number of next/previous records to return. For example, let's say I have 5 records: Record1 Record2 Record3 Record4 Record5 I want to be able to call Model.previous or Model.previous(1) to return Record2. Similarly, I want to be able to call Model.next or Model.next(1) to return Record4. As another example I want to be able to call Model.previous(2) to return Record3. I think you get the idea. How can I accomplish this?

  • ASP.NET variable scope

    - by c11ada
    hey all, im really new to ASP.Net and still havnt got my head round most of the concepts, im really having problems with variable, when creating a desktop application, any variable created in code for example int n = 10; this variable will be there until the program is running right. but in asp iv created variables which are supposed to last until the user gets of that page, so for example say i have a page which takes the users value ( call this variable n say the user type in 10) and every time the user presses the next button the code add 10 to this value. so the first time the user presses the next button n= n + 10; what i have found is no matter how many times i press the next button n will always equal 20, because the previous value is not saved !! these values are populated the first time the user enters that page, once the user clicks the next button the content of these values disappear! how can stop this from happening ?? hope this makes sense !! thanks

  • Remove Activity as Default Launcher

    - by sixeightzero
    I set my activity as a default launcher to intercept home button clicks like so: <activity android:name=".ExampleActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> <category android:name="android.intent.category.HOME" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> When my activity, ExampleActivity is launched, if i click the home key, I get prompted to choose. If I select make this my default and chose my activity, I am stuck In my activity as desired. The problem is, when I leave the activity, I try to remove my activity from the default launcher, but am unsuccessful. I have tried: ComponentName componentName = new ComponentName( "com.example.exampleactivity", "com.example.exampleactivity.class"); pm.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DEFAULT, PackageManager.DONT_KILL_APP); And: PackageManager pm = getActivity().getPackageManager(); ComponentName name = new ComponentName(this, "com.example.exampleactivity.class"); pm.setComponentEnabledSetting(name, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 0); But my designation for the home is never removed. Does anyone have a working way to fix the above? I only wan't the home button to be default for a specific activity, not my entire application. When I leave the activity, it should be removed and restored to default.

  • Need an end of lexical scope action which can die normally

    - by Schwern
    I need the ability to add actions to the end of a lexical block where the action might die. And I need the exception to be thrown normally and be able to be caught normally. Unfortunately, Perl special cases exceptions during DESTROY both by adding "(in cleanup)" to the message and making them untrappable. For example: { package Guard; use strict; use warnings; sub new { my $class = shift; my $code = shift; return bless $code, $class; } sub DESTROY { my $self = shift; $self->(); } } use Test::More tests => 2; my $guard_triggered = 0; ok !eval { my $guard = Guard->new( #line 24 sub { $guard_triggered++; die "En guarde!" } ); 1; }, "the guard died"; is $@, "En guarde! at $@ line 24\n", "with the right error message"; is $guard_triggered, 1, "the guard worked"; I want that to pass. Currently the exception is totally swallowed by the eval. This is for Test::Builder2, so I cannot use anything but pure Perl. The underlying issue is I have code like this: { $self->setup; $user_code->(); $self->cleanup; } That cleanup must happen even if the $user_code dies, else $self gets into a weird state. So I did this: { $self->setup; my $guard = Guard->new(sub { $self->cleanup }); $user_code->(); } The complexity comes because the cleanup runs arbitrary user code and it is a use case where that code will die. I expect that exception to be trappable and unaltered by the guard. I'm avoiding wrapping everything in eval blocks because of the way that alters the stack.

  • C++ stack memory still valid?

    - by jbu
    Hi all, If I create an object on the stack and push it into a list, then the object loses scope (outside of the for loop in the example below) will the object still exist in the list? If the list still holds the object, is that data now invalid/possibly corrupt? Please let me know, and please explain the reasoning.. Thanks, jbu class SomeObject{ public: AnotherObject x; } //And then... void someMethod() { std::list<SomeObject> my_list; for(int i = 0; i < SOME_NUMBER; i++) { SomeObject tmp; my_list.push_back(tmp); //after the for loop iteration, tmp loses scope } my_list.front(); //at this point will my_list be full of valid SomeObjects or will the SomeObjects no longer be valid, even if they still point to dirty data }
