  • Green part in Visual Studio 2010

    - by Braveyard
    I am wondering what these greens things are in Visual Studio 2010. What are they for? They look pretty random but of course they have to have some meaning. Can any one tell me? At first glance they don't mean any thing to me. Picture 1: Picture 2:

  • C# Async call garbage collection

    - by Troy
    Hello. I am working on a Silverlight/WCF application and of course have numerous async calls throughout the Silverlight program. I was wondering on how is the best way to handle the creation of the client classes and subscribing. Specifically, if I subscribe to an event in a method, after it returns does it fall out of scope? internal MyClass { public void OnMyButtonClicked() { var wcfClient = new WcfClient(); wcfClient.SomeMethodFinished += OnMethodCompleted; wcfClient.SomeMethodAsync(); } private void OnMethodCompleted(object sender, EventArgs args) { //Do something with the result //After this method does the subscription to the event //fall out of scope for garbage collection? } } Will I run into problems if I call the function again and create another subscription? Thanks in advance to anyone who responds.

  • Reducing width of bar chart series

    - by gAMBOOKa
    Note: by width i mean the height here, I use width because by default, bar charts are vertical and flex uses the width property I want to reduce the width of the following barchart so Type 5, Type 4, Type 3, Type 2, Type 1 are very close to each other. I tried playing with the barWidthRatio, the horizontalAxisRatio and the maxBarWidth properties. Neither is giving me the desired result. I can only manage to reduce the width of the orange bars, how do I reduce the width of the blue bars?

  • How to access items by "group" in an Outlook VB macro?

    - by Noah Yetter
    By "group" I mean the collapsible classifications that you get when you enable View-Arrange By-Show in Groups. This divides e.g. messages in a folder into Today, Yesterday, Last Week, Two Weeks Ago, and so on. What I'd like to be able to do is iterate over the messages that are currently classified within a given group. Is this possible?

  • Log information inside a JUnit Suite

    - by Alex Marinescu
    I'm currently trying to write inside a log file the total number of failed tests from a JUnite Suite. My testsuite is defined as follows: @RunWith(Suite.class) @SuiteClasses({Class1.class, Class2.class etc.}) public class SimpleTestSuite {} I tried to define a rule which would increase the total number of errors when a test fails, but apparently my rule is never called. @Rule public MethodRule logWatchRule = new TestWatchman() { public void failed(Throwable e, FrameworkMethod method) { errors += 1; } public void succeeded(FrameworkMethod method) { } }; Any ideas on what I should to do to achieve this behaviour?

    - by Greg
    Hi all, I'm trying to set up the Android SDK on Ubuntu. Someday I want to make apps that can reach most of the market. I've heard I need to make the apps compatible with Android 1.6 for this.

  • How to solve the leaks when allocating the NSMutableArray in Objective-C

    - by Madan Mohan
    Hi Guys, I am getting leaks in Master view controller of iPhone. When I call this method, I am inserting them into filteredListCount array, because when I search I need to show the list from filteredListCount array otherwise customerArray. This functionality is working fine but I am getting leaks in the method below at allocation: filteredListCount = [[NSMutableArray alloc] initWithCapacity: [customerArray count]]; This is the first view controller of my application, I am showing the list and I am also allowing to search from a list. - (void)parser:(CustomerListLibXmlParser *)parser addCustomerObject:(Customer *)customerObj1 { [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [customerArray addObject:customerObj1]; filteredListCount = [[NSMutableArray alloc] initWithCapacity: [customerArray count]]; [filteredListCount addObjectsFromArray: customerArray]; [theTableView reloadData]; } - (void)parser:(CustomerListLibXmlParser *)parser encounteredError:(NSError *)error { } - (void)parserFinished:(CustomerListLibXmlParser *)parser { [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; self.title=@"Customers"; }

  • Catching "NullPointerExceptions" in JavaScript

    - by Lenni
    I'm writing quite a bit of code in Prototype.js which returns null if a DOM-id wasn't found. $("someId").show(); If someId doesn't exist, a method will be called on null, which halts the entire program, in effect disabling all JS effects after the error. I could just check for null before executing such a statement, but this is getting tiring. I would like to catch an exception but I'm not sure which one its is. MDC lists the following ECMA Script error types: * Error * EvalError * RangeError * ReferenceError * SyntaxError * TypeError * URIError * DOMException * EventException * RangeException Also, do browsers have a unified way of dealing with a method call on null?

  • propertyplaceholderconfigurer class name substitution problem

    - by Alex
    The following example works for "class name substitution using the PropertyPlaceHolderConfigurer": http://forum.springsource.org/showpost.php?p=228136&postcount=2 HOWEVER, when porting this code over (messages.properties, com.spring.ioc.TestClass, and spring-config.xml) to a web application, the class name substitution now fails! 1) I am running on the webapp on Tomcat through the Eclipse plugin. 2) In the web.xml I have the following: <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-config.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> 3) The following is output in the log: 282 [main] DEBUG org.springframework.beans.factory.support.DefaultListableBeanFactory - Ignoring bean class loading failure for bean 'test' org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [${test.class}] for bean with name 'test' defined in ServletContext resource [/WEB-INF/spring-config.xml]; nested exception is java.lang.ClassNotFoundException: ${test.class} at org.springframework.beans.factory.support.AbstractBeanFactory.resolveBeanClass(AbstractBeanFactory.java:1141) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.predictBeanType(AbstractAutowireCapableBeanFactory.java:524) at org.springframework.beans.factory.support.AbstractBeanFactory.isFactoryBean(AbstractBeanFactory.java:1177) at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanNamesForType(DefaultListableBeanFactory.java:222) at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:505) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:362) at org.springframework.web.context.ContextLoader.createWebApplicationContext(ContextLoader.java:255) at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:199) at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:45) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3795) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4252) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1014) at org.apache.catalina.core.StandardHost.start(StandardHost.java:736) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1014) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:443) at org.apache.catalina.core.StandardService.start(StandardService.java:448) at org.apache.catalina.core.StandardServer.start(StandardServer.java:700) at org.apache.catalina.startup.Catalina.start(Catalina.java:552) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:295) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:433) Caused by: java.lang.ClassNotFoundException: ${test.class} at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1438) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1284) at org.springframework.util.ClassUtils.forName(ClassUtils.java:211) at org.springframework.beans.factory.support.AbstractBeanDefinition.resolveBeanClass(AbstractBeanDefinition.java:385) at org.springframework.beans.factory.support.AbstractBeanFactory.resolveBeanClass(AbstractBeanFactory.java:1138) ... 23 more Note: I haven't included it, but the PropertyPlaceHolderConfigurer is successfully locating the messages.properties file, but this seems to happen AFTER the above error is output?!

  • python command line yes/no input

    - by h3
    Is there any short way to achieve what APT does in Python ? I mean, when the package manager prompts a yes/no question followed by "[Yes/no]". The scripts accepts YES/Y/yes/y or "enter" (defaults to Yes as hinted by the capital) The only thing I find in the official doc is input/raw_input.. I know it's not that hard to emulate, but it's annoying to rewrite :|

  • jQuery variables and scope

    - by Peuge
    I am writing a jQuery plugin and am running into a few problems with regard to variables. For example I have the following skeleton structure for my plugin, which is going to act on a textbox. In my init function I want to set a variable and bind a keypress event to my textbox. That keypress event needs to call another function, in which I need the variable. Is this possible? (function($){ var methods = { init : function(options){ return this.each(function(){ var $this = $(this); var someVar = 'somevar'; $this.keypress(function(event){ //I want to call my customFunction }); }); }, customFunction : function(){ //I am wanting to access 'someVar' here }; $.fn.mynamespace = function(method){ //handle which method to call here }; })(jQuery); Many thanks in advance.

  • How to implement async pattern in windows forms application?

    - by Alkersan
    I'm using an MVC pattern in winforms application. I need to call remote service asynchronously. So On some event in View I invoke corresponding Presenter method. In Presenter I call BeginInvoke method of service. But to View must be updated only in Main Thread. I could actualy point CallBack to some function in View, and update it`s controls state, but this conflicts with MVP pattern - View must not be responsible for data it carries. This callback function must be in Presenter. But how then invoke View in Main Thread?

  • iPhone app launch times and Core Data migration

    - by sehugg
    I have a Core Data application which I plan to update with a new schema. The lightweight migration seems to work, but it takes time proportional to the amount of data in the database. This occurs in the didFinishLaunchingWithOptions phase of the app. I want to avoid <app> failed to launch in time problems, so I assume I cannot keep the migration in the didFinishLaunchingWithOptions method. I assume the best method would involve performing the migration in a background thread. I assume also that I'd need to defer loading of the main ViewController until the loading completes to avoid using the managedObjectContext until initialization completes. Does this make sense, and is there example code (maybe in Apple sample projects) of this sort of initialization?

  • Can Adobe AIR display SVG?

    - by Ed Thomas
    I see that Adobe AIR uses WebKit as its render and I see that WebKit (at least the most current build) has some SVG support. Does this mean (and has anyone specifically tried) that an Adobe AIR application could render SVG on an HTML page?

  • Java: Selected rows's index does not changes when I sort them!

    - by adrian7
    Hello, I have a Jtable on which I called the method table1.setAutoCreateRowSorter(true);. So this works on well. But I also have a methos in my JFrame class which is fired when i push a button. It gets the selected rows indexes using this code int selectedRows[] = this.table1.getSelectedRows();. And displays an edit window for the first row corresponding in the selected interval. The problem is that if I don't click on column's headers (I mean i don't sorte them at all) my method works perfect. But when I sort the row, the indexes of the rows doesn't seems to change at all - thus resulting an edit window for the old row whicn was initially in that position before making any sort. I am using JDK 6 could anyonw give ma a tip?

  • Getting user data from Active Directory using PL/SQL

    - by David Neale
    I had a discussion today regarding an Oracle procedure I wrote some time ago. I wanted to get 7500 user email addresses from Active Directory using PL/SQL. AD will return a maximum of 1000 rows and the LDAP provider used by Oracle will not support paging. Therefore, my solution was to filter on the last two characters of the sAMAccountName (*00,*01,*02...etc.). This results in 126 queries (100 for account names ending in digits, 26 for those ending in a letter...this was sufficient for my AD setup). The person I was speaking to (it was a job interview by the way) said he could have done it a better way, but he would not tell me what that method was. Could anybody hazard a guess at what this method was?
