  • Windows 8.1 Search does not automatically select first search match

    - by Miguel Sevilla
    When I search in Windows 8/8.1 (start menu-start typing), it doesn't automatically highlight the search term. For example, if I'm trying to open the "Internet Options" panel and type the entire thing out in search, I have to down arrow or tab to the "Internet Options" search result. This is retarded. I'm used to Windows 7 style search where the first match is highlighted and i can easily just hit return. First match highlighting does work for other built-in things like "Control Panel", but it should work for all things in general, as it did in Windows 7 search. Anyways, if there is an option to enable this in Windows 8/8.1, I'd appreciate the tip. Thanks!

  • replica set with multiple primary nodes

    - by miguel
    I am trying to configure a replica set with three nodes: node A, B and C. I execute the rs.add()'s from node A and after that rs.status() shows that the three nodes are PRIMARY. Moreover node B and C have 0 pingMs. If I execute rs.status() from node B or C the only node listed is the self (As PRIMARY). I tried adding an arbiter but it didn't work (it behaved as the nodes B and C). I think this can be a networking problem but I can't figure it out. Edit: This is the output for netstat -anp|grep 27017: tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN - tcp 0 0 10.0.1.211:55772 10.0.1.213:27017 TIME_WAIT - tcp 0 0 127.0.0.1:50509 127.0.0.1:27017 ESTABLISHED - tcp 0 0 127.0.0.1:27017 127.0.0.1:50509 ESTABLISHED - tcp 0 0 10.0.1.211:55774 10.0.1.213:27017 TIME_WAIT - tcp 0 0 10.0.1.211:55776 10.0.1.213:27017 ESTABLISHED - tcp 0 0 10.0.1.211:39180 10.0.1.212:27017 ESTABLISHED - tcp 0 0 10.0.1.211:39178 10.0.1.212:27017 TIME_WAIT - tcp 0 0 10.0.1.211:39176 10.0.1.212:27017 TIME_WAIT - unix 2 [ ACC ] STREAM LISTENING 3291267 - /tmp/mongodb-27017.sock the private ips for the node B and C are 10.0.1.212 and 10.0.1.213 respectively (they appear to have an established connection in the 27017 port according to the netstat output).

  • DynamicResource and Dynamic Items in ContextMenu on XamDataGrid

    - by miguel
    I would like to dynamically create a set of context menu options based upon some properties. Currently, I am creating a context menu as a DynamicResource with the visibility of the menu options bound to the properties, however, it seems that the DynamicResource is created only once, at runtime. Is this true? What I would like to do is have the menu generated each time, which will take into account the property changes on the data object. Please see the following XAML snippet: <Border DockPanel.Dock="Right" Margin="4,4,4,4" BorderBrush="Gray" BorderThickness="1" CornerRadius="3" > <igDP:XamDataGrid Height="Auto" Width="Auto" Style="{DynamicResource DefaultInfragisticsGridStyle}" Name="axeDataGrid" ActiveRecord="{Binding Path=SelectedItem, Mode=TwoWay}" DataSource="{Binding Path=Axes}" ContextMenuOpening="ContextMenuOpeningHandler"> <igDP:XamDataGrid.Resources> <Style TargetType="{x:Type igDP:DataRecordPresenter}" BasedOn="{x:Static Themes:DataPresenterAero.DataRecordPresenter}"/> <ContextMenu x:Key="RecordContextMenu"> <ContextMenu.Resources> <BooleanToVisibilityConverter x:Key="booleanToVisibilityConverter"/> </ContextMenu.Resources> <MenuItem Header="Cancel Axe" Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igDP:XamDataGrid}}, Path=DataContext.CancelAxe}" Visibility="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igDP:XamDataGrid}}, Path=DataContext.IsCancelAxeAllowed, Converter={StaticResource booleanToVisibilityConverter}, Mode=OneWay}"/> <MenuItem Header="Create RFQ" Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igDP:XamDataGrid}}, Path=DataContext.CreateRFQ}" Visibility="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igDP:XamDataGrid}}, Path=DataContext.IsCreateRfqAllowed, Converter={StaticResource booleanToVisibilityConverter}, Mode=OneWay}"/> </ContextMenu> <Style TargetType="{x:Type igDP:DataRecordCellArea}"> <Setter Property="ContextMenu" Value="{DynamicResource RecordContextMenu}" /> </Style>

  • Passing List of Strings or Array of strings into Unity Injection Constructor (Config-Based)

    - by miguel
    I cannot seem to get unity working when attempting to pass in an array of strings into a constructor parameter list, while using XML configuration. When I try the following: <typeConfig ...> <constructor ...> <param ... parameterType="System.String[]"> <array> <value.../> <value.../> </array> </param> </constructor> </typeConfig> for a c'tor which looks like this: void Foo(string[] inputParams_){ ... } It always fails in Unity's FindConstructor(...) method stating that it cannot find a c'tor mathcing the parameter type of String.String Does anyone know how to pass an array of stings successfully into this type of c'tor? If not, how can I do so with a list of strings, if the c'tor were to accept an IList? Thanks!

  • FluentNhibernate IDictionary<Entity,ValueObject>

    - by Miguel Marques
    I had a mapping for a IDictionary<StocksLocation,decimal> property, this was the mapping: HasMany<StocksLocation>(mq => mq.StocksLocation) .KeyColumn("IDProduct") .AsEntityMap("IDLocation") .Element("Quantity", qt => qt.Type<decimal>()); Now i changed from decimal to a Value Object: Quantity. Quantity has two properties, decimal Value and Unit Unit (where Unit is an enum). I now have to map IDictionary<StocksLocation,Quantity>, how can i achieve this? Thanks in advance

  • HP-UX: libstd_v2 in stack trace of JNI code compiled with g++

    Hello, uname -mr: B.11.23 ia64 g++ --version: g++ (GCC) 4.4.0 java -version: Java(TM) SE Runtime Environment (build 1.6.0.06-jinteg_20_jan_2010_05_50-b00) Java HotSpot(TM) Server VM (build 14.3-b01-jre1.6.0.06-rc1, mixed mode) I'm trying to run a Java application that uses JNI.

The crash happens in the following code, when method str() returns: class JniString { std::string m_utf8; public: JniString(JNIEnv* env, jstring instance) { const char* utf8Chars = env-GetStringUTFChars(instance, 0); if (utf8Chars == 0) { env-ExceptionClear(); // RPF throw std::runtime_error("GetStringUTFChars returned 0"); } m_utf8.assign(utf8Chars); env-ReleaseStringUTFChars(instance, utf8Chars); } std::string str() const { return m_utf8; } }; Simultaneous usage of the two C++ implementations could likely be a reason for the crash, but that should not be happening. Any ideas?

  • Nhibernate: distinct results in second level Collection

    - by Miguel Marques
    I have an object model like this: class EntityA { ... IList<EntityB> BList; ... } class EntityB { ... IList<EntityC> CList; } I have to fetch all the colelctions (Blist in EntityA and CList in EntityB), because if they all will be needed to make some operations, if i don't eager load them i will have the select n+1 problem. So the query was this: select a from EntityA a left join fetch a.BList b left join fetch b.CList c The fist problem i faced with this query, was the return of duplicates from the DB, i had EntityA duplicates, because of the left join fetch with BList. A quick read through the hibernate documentation and there were some solutions, first i tried the distinct keyword that supposelly wouldn't replicate the SQL distinct keyword except in some cases, maybe this was one of those cases because i had a SQL error saying that i cannot select distict text columns (column [Observations] in EntityA table). So i used one of the other solutions: query.SetResultTransformer(new DistinctRootEntityResultTransformer()); This worked fine. But the result of the operations were still not passing the tests. I checked further and i found out that now there were duplicates of EntityB, because of the left join fetch with CList. The question is, how can i use the distinct in a second level collection? I searched and i only find solutions for the root entity's direct child collection, but never for the second level child collections... Thank you for your time

  • How do I get google guice to inject a custom logger, say a commons-logging or log4j logger

    - by Miguel Silva
    Google guice has a built-in logger binding (http://code.google.com/p/google-guice/wiki/BuiltInBindings). But what if I want to use a commons-logging or log4j logger? Can I get guice to inject a Log created by LogFactory.getLog(CLASS.class) But having the same behavior as in built-in binding: The binding automatically sets the logger's name to the name of the class into which the Logger is being injected.. Does it even makes sense? Or shout I simply use the built-in java Logger? Or just use commons-logging without injections?

  • How does the Control class, provide the ForeColor, BackColor and Font default values?

    - by Miguel Angelo
    I know that component-model indicates whether a property has a default value or not, by means of ShouldSerializeValue method of PropertyDescriptor. The base windows-forms Control class, has some properties like ForeColor, BackColor and Font, that defaults to the same value of the parent, but I could not find any TypeDescriptor or PropertyDescriptor that provides these default values. The Control class does not implement ICustomTypeDescriptor nor has a TypeDescriptionProviderAttribute. How does the Control class indicates that these properties should be serialized or not? Where does it provide the PropertyDescriptors for these properties?? Thanks!!!

  • How are DynamicResources built and their use in contextmenus.

    - by miguel
    Are dynamic resources truly dynamic? If I define a DynamicResource, I realise that an expression is created (where?) that is not translated into a resource until runtime, however, What I do not understans is whether this dynamicresouce, once built, is now "Static" For instance, if I create a context menu via a dynamicresource, are the menuitems which are created at runtime on access then static, even if they are bound? If so, how can i create a dynamic context menu in XAML?

  • Dereferencing pointers without pointing them at a variable

    - by Miguel
    I'm having trouble understanding how some pointers work. I always thought that when you created a pointer variable (p), you couldn't deference and assign (*p = value) unless you either malloc'd space for it (p = malloc(x)), or set it to the address of another variable (p = &a) However in this code, the first assignment works consistently, while the last one causes a segfault: typedef struct { int value; } test_struct; int main(void) { //This works int* colin; *colin = 5; //This never works test_struct* carter; carter->value = 5; } Why does the first one work when colin isn't pointing at any spare memory? And why does the 2nd never work? I'm writing this in C, but people with C++ knowledge should be able to answer this as well.

  • CSS: achieving TWO-WAY infinite scroll with mouse drag

    - by Miguel Ping
    Hi, I'm trying to create an infinite scroll component. I'm using this site as a tutorial, but it seems that I can only get the infinite scroll on one way, because when I add elements to the leftmost side, the scrollLeft property auto-adjusts thus the page gets a quirky scroll, jumping instead of making a smooth movement. Is there any way of achieving infinite scroll both-ways? I don't plan to use scrolling buttons, just mouse drag for moving the scroll view.

  • Inherit from Type class of .Net

    - by Miguel Angelo
    Is there any point at all on inheriting from Type class in .Net? i.e. What could be the meaning of doing so? I am asking this because of this text in MSDN documentation: Notes to Inheritors When you inherit from Type, you must override the following members... list of members. MSDN doc for Type: http://msdn.microsoft.com/en-us/library/system.type.aspx ok, that is actually saying that anyone can inherit from Type... but they dont say why would you ever want to do that. Thanks!

  • Thread Local Storage and local method variables

    - by miguel
    In c#, each thread has its own stack space. If this is the case, why is the following code not thread-safe? (It is stated that this code is thread-safe on this post: Locking in C# class Foo { private int count = 0; public void TrySomething() { count++; } } As count is an int (stack variable), surely this value would be isolated to an individual thread, on its own stack, and therefore thread-safe? I am probably missing something here, but I dont understand what is actually in Thread Local Storage if not stack-based variables for the thread?

I currently have two drupal sites there, let's called the main myMainSite and another one under construction called myNewSite. So when I go to www.myMainSite.com, I go to the main site. When I go to myNewSite.myMainSite.com, i go to the drupal site that is under construction. My question is, when my under construction site goes live, I want that all users that go to www.myMainSite.com see the new site (the one that is under myNewSite.myMainSite.com). How can I accomplish this with cpanel? is it within the "addon domains" configuration? I don't want a redirect that changes the address bar, ie, I want to keep the original url.

  • Is there anyway to exclude artifacts inherited from a parent POM?

    - by Miguel
    Artifacts from dependencies can be excluded by declaring an <exclusions> element inside a <dependency> But in this case it's needed to exclude an artifact inherited from a parent project. An excerpt of the POM under discussion follows: <project> <modelVersion>4.0.0</modelVersion> <groupId>test</groupId> <artifactId>jruby</artifactId> <version>0.0.1-SNAPSHOT</version> <parent> <artifactId>base</artifactId> <groupId>es.uniovi.innova</groupId> <version>1.0.0</version> </parent> <dependencies> <dependency> <groupId>com.liferay.portal</groupId> <artifactId>ALL-DEPS</artifactId> <version>1.0</version> <scope>provided</scope> <type>pom</type> </dependency> </dependencies> </project> base artifact, depends on javax.mail:mail-1.4.jar, and ALL-DEPS depends on another version of the same library. Due to the fact that mail.jar from ALL-DEPS exist on the execution environment, although not exported, collides with the mail.jar that exists on the parent, which is scoped as compile. A solution could be to rid off mail.jar from the parent POM, but most of the projects that inherit base, need it (as is a transtive dependency for log4j). So What I would like to do is to simply exclude parent's library from the child project, as it could be done if base was a dependency and not the parent pom: ... <dependency> <artifactId>base</artifactId> <groupId>es.uniovi.innova</groupId> <version>1.0.0</version> <type>pom<type> <exclusions> <exclusion> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> </exclusion> </exclusions> </dependency> ...

  • Guidelines of when to use locking

    - by miguel
    I would like to know if there are any guidelineswhich a developer should follow as to when (and where) to place locks. For instance: I understand that code such as this should be locked, to avoid the possibility of another thread changing the value of SomeHeapValue unexpectedly. class Foo { public SomeHeapObject myObject; public void DoSummat(object inputValue_) { myObject.SomeHeapValue = inputValue_; } } My question is, however, how deep does one go with the locking? For instance, if we have this code: class Foo { public SomeHeapObject myObject; public void DoSummat(object inputValue_) { myObject.SomeHeapValue = GetSomeHeapValue(); } } Should we lock in the DoSummat(...) method, or should we lock in the GetSomeHeapValue() method? Are there any guidelines that you all keep in mind when strcturing multi-threaded code?
