  • Watir question regarding select_list and reloading

    - by AJ
    I have a drop down with multiple options. Whenever you choose an option, the page reloads with data specific with that option. Currently I'm using select.list(:name, strg).set(value) and it does that part just fine, but it does not reload the page with the specific data. Anyone know how to help. When i watch it in action, it doesn't select the option either, but my logs show that it does.Thanks.

  • How do I set the dataProvider for an <s:List> component to be an XML file?

    - by Matt Calthrop
    I've got the latest Beta of Adobe Flash Builder 4. I want to use a <s:List> component, and specify the dataProvider as being an XML file. However, after loads of research (including looking at doc links off labs.adobe.com), I still can't figure out how to do it. The XML file will look something like this: <?xml version="1.0" encoding="ISO-8859-1"?> <imageList> <image location="path/to/file1.jpg" /> <image location="path/to/file2.jpg" /> <image location="path/to/file3.jpg" /> </imageList>

  • How do I configure encodings (UTF-8) for code executed by Quartz scheduled Jobs in Spring framework

    - by Martin
    I wonder how to configure Quartz scheduled job threads to reflect proper encoding. Code which otherwise executes fine within Springframework injection loaded webapps (java) will get encoding issues when run in threads scheduled by quartz. Is there anyone who can help me out? All source is compiled using maven2 with source and file encodings configured as UTF-8. In the quartz threads any string will have encoding errors if outside ISO 8859-1 characters: Example config <bean name="jobDetail" class="org.springframework.scheduling.quartz.JobDetailBean"> <property name="jobClass" value="example.ExampleJob" /> </bean> <bean id="jobTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean"> <property name="jobDetail" ref="jobDetail" /> <property name="startDelay" value="1000" /> <property name="repeatCount" value="0" /> <property name="repeatInterval" value="1" /> </bean> <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref bean="jobTrigger"/> </list> </property> </bean> Example implementation public class ExampleJob extends QuartzJobBean { private Log log = LogFactory.getLog(ExampleJob.class); protected void executeInternal(JobExecutionContext ctx) throws JobExecutionException { log.info("ÅÄÖ"); log.info(Charset.defaultCharset()); } } Example output 2010-05-20 17:04:38,285 1342 INFO [QuartzScheduler_Worker-9] ExampleJob - vÖvÑvñ 2010-05-20 17:04:38,286 1343 INFO [QuartzScheduler_Worker-9] ExampleJob - UTF-8 The same lines of code executed within spring injected beans referenced by servlets in the web-container will output proper encoding. What is it that make Quartz threads encoding dependent?

  • How do I ensure a Flex dataProvider processes the data synchronously?

    - by Matt Calthrop
    I am using an component, and currently have a dataProvider working that is an ArrayCollection (have a separate question about how to make this an XML file... but I digress). Variable declaration looks like this: [Bindable] private var _dpImageList : ArrayCollection = new ArrayCollection([ {"location" : "path/to/image1.jpg"}, {"location" : "path/to/image2.jpg"}, {"location" : "path/to/image3.jpg"} ]); I then refer to like this: <s:List id="lstImages" width="100%" dataProvider="{_dpImageList}" itemRenderer="path.to.render.ImageRenderer" skinClass="path.to.skins.ListSkin" > <s:layout> <s:HorizontalLayout gap="2" /> </s:layout> </s:List> Currently, it would appear that each item is processed asynchronously. However, I want them to be processed synchronously. Reason: I am displaying a list of images, and I want the leftmost one rendered first, followed by the one to its right, and so on. Edit: I just found this answer. Do you think that could be the same issue?

  • Sharepoint - how to set permission level to add item but not view?

    - by Stuart
    I want to allow a certain group of users to add items to a list, but not be able to view all items. This is so I can set up a workflow with certain parts of it private. I thought it'd be possible by defining a new permission level in: http://servername/_layouts/addrole.aspx ('Add a permission level' page) However, when you select the "add items" list permission, "view items" is automatically ticked also. Anyone know a solution to this?

  • Detecting support for a given JavaScript event?

    - by Will
    I'm interested in using the JavaScript hashchange event to monitor changes in the URL's fragment identifier. I'm aware of Really Simple History and the jQuery plugins for this. However, I've reached the conclusion that in my particular project it's not really worth the added overhead of another JS file. What I would like to do instead is take the "progressive enhancement" route. That is, I want to test whether the hashchange event is supported by the visitor's browser, and write my code to use it if it's available, as an enhancement rather than a core feature. IE 8, Firefox 3.6, and Chrome 4.1.249 support it, and that accounts for about 20% of my site's traffic. So, uh ... is there some way to test whether a browser supports a particular event? Thanks.

  • drupal hook_menu_alter() for adding tabs

    - by EricP
    I want to add some tabs in the "node/%/edit" page from my module called "cssswitch". When I click "Rebuild Menus", the two new tabs are displayed, but they are displayed for ALL nodes when editing them, not just for the node "cssswitch". I want these new tabs to be displayed only when editing node of type "cssswitch". The other problem is when I clear all cache, the tabs completely dissapear from all edit pages. Below is the code I wrote. function cssswitch_menu_alter(&$items) { $node = menu_get_object(); //print_r($node); //echo $node->type; //exit(); if ($node->type == 'cssswitch') { $items['node/%/edit/schedulenew'] = array( 'title' => 'Schedule1', 'access callback'=>'user_access', 'access arguments'=>array('view cssswitch'), 'page callback' => 'cssswitch_schedule', 'page arguments' => array(1), 'type' => MENU_LOCAL_TASK, 'weight'=>4, ); $items['node/%/edit/schedulenew2'] = array( 'title' => 'Schedule2', 'access callback'=>'user_access', 'access arguments'=>array('view cssswitch'), 'page callback' => 'cssswitch_test2', 'page arguments' => array(1), 'type' => MENU_LOCAL_TASK, 'weight'=>3, ); } } function cssswitch_test(){ return 'test'; } function cssswitch_test2(){ return 'test2'; } Thanks for any help.

  • Errors with large data sources

    - by The Sheek Geek
    I'm doing some benchmarking on large data sources and binding/exporting data for reporting. I started with using a data set, filling it with 100000 rows and then attempting to open a crystal report with the retrieved data. I noticed that the data set filled just fine (took about 779 milliseconds) however, when attempting to export the data to the report or even bind to a gridview the application would fail with an OutOfMemoryException. Does anyone experienced this before or have an idea of how to get around it? It is very possible that clients will run reports for years worth of data and 100000 rows are not inconceivable. The application and the benchmark code are written in C# using ORACLE and SQL Server databases. I still have some data sources to test, but would like to know how to get around this just in case I don't find a better solution.

  • Linking/Combining Type Classes in Haskell

    - by thegravian
    Say I have two type classes defined as follows that are identical in function but different in names: class Monad m where (>>=) :: m a -> (a -> m b) -> m b return :: a -> m a class PhantomMonad p where pbind :: p a -> (a -> p b) -> p b preturn :: a -> p b Is there a way to tie these two classes together so something that is an instance of PhantomMonad will automatically be an instance of Monad, or will instances for each class have to be explicitly written? Any insight would be most appreciated, thanks!

  • Converting "fr_FR" into "French (France)" in both directions. (Objective-C iPhone)

    - by Janice
    I can easily change a short region-code (en_US) into a longer string... but it there an easy way to also move in the other direction? [displayInEnglish displayNameForKey:NSLocaleIdentifier value:regionCountryCode]; "en_US" becomes "English (United States)". "English (United States)" becomes "en_US". I currently store the short region-code in a database.... but when I show some aggregate results... I need to display the longer strings to the user. Or should I just store the longer strings right in the database... and not even worry about "converting" them later? I'm trying to show a "dollars total" for each country. If you were a user... which would you more likely wish to see (for a currency-total list)? A "French" total A "France" total A "French (France)" total A "fr_Fr" total?

  • Is there a difference between NSString compare: and isEqual(ToString): ?

    - by frenetisch applaudierend
    Occasionally I find code which tests if two NSStrings are the same like this: if ([str1 compare:str2] == NSOrderedSame) { // Do something } Now, I believe this is less readable than using isEqualToString: and it also has some nasty side effects, like if str1 == nil the if(..) evaluates to true, or when str2 == nil havoc might break upon us according to the Apple docs. But before I crusade against those statements in my companys code, I wanted to make sure I didn't miss some important point. So my question basically boils down to: Is there any difference between a compare: to NSOrderedSame and isEqual:?

  • what is meant by normalization in huge pointers

    - by wrapperm
    Hi, I have a lot of confusion on understanding the difference between a "far" pointer and "huge" pointer, searched for it all over in google for a solution, couldnot find one. Can any one explain me the difference between the two. Also, what is the exact normalization concept related to huge pointers. Please donot give me the following or any similar answers: "The only difference between a far pointer and a huge pointer is that a huge pointer is normalized by the compiler. A normalized pointer is one that has as much of the address as possible in the segment, meaning that the offset is never larger than 15. A huge pointer is normalized only when pointer arithmetic is performed on it. It is not normalized when an assignment is made. You can cause it to be normalized without changing the value by incrementing and then decrementing it. The offset must be less than 16 because the segment can represent any value greater than or equal to 16 (e.g. Absolute address 0x17 in a normalized form would be 0001:0001. While a far pointer could address the absolute address 0x17 with 0000:0017, this is not a valid huge (normalized) pointer because the offset is greater than 0000F.). Huge pointers can also be incremented and decremented using arithmetic operators, but since they are normalized they will not wrap like far pointers." Here the normalization concept is not very well explained, or may be I'm unable to understand it very well. Can anyone try explaining this concept from a beginners point of view. Thanks, Rahamath

  • Can you embed PHP code in the output of a CGI script?

    - by Joe Corkery
    I have a CGI based form that I am working with and I would like to be able to include some PHP code in the generated results. However, when I do this, the PHP does not appear to get processed and just ends up being displayed in the resulting web page. Is what I am doing actually possible or am I missing something? Thanks.

  • Do I have to worry about escaping XML reserved characters before I return a DataContract object from

    - by Brett Widmeier
    Hi, I am pretty inexperienced with WCF. I have a DataContract that implements the IExtensibleDataObject interface. Some of the members of this object are populated from freetext input and could contain XML reserved characters ('', for example). I imagine that I get escaping of these characters for free with WCF, but I have been looking around and could not find anything commenting on this one way or another. Is this the case? I have set my service to log the messages that it sends and receives for viewing in the Trace Viewer. Part of a message that my service returns looks like this: <sInstructions>"></sInstructions> Now, I have a couple questions about this. 1) Is it actually transmitting "&gt; and just showing it in a more readable form in the trace viewer? 2) If it is actually is transmitting ">, is this legal XML?

  • Looking for jQuery slideshow where a user can hide/show a block of text (link, caption)

    - by hollyb
    I'm looking to implement a fairly basic jQuery slideshow. One that automatically loops through a set number of images. The snag I'm running into is i'd like to have a little icon in the corner of the picture, that when clicked, brings up a transparent black bar across the bottom with some text and perhaps a link. Has anybody come across anything like this? This gallery is close, but lacks user control for showing/hiding the caption (and might be somewhat restrictive of what text can be used): http://www.queness.com/resources/html/slideshow/jquery-slideshow.html Anyway, if anybody has any tips or links that would be great. Thanks.

  • Java Runtime.getRuntime().exec() alternatives

    - by twilbrand
    I have a collection of webapps that are running under tomcat. Tomcat is configured to have as much as 2 GB of memory using the -Xmx argument. Many of the webapps need to perform a task that ends up making use of the following code: Runtime runtime = Runtime.getRuntime(); Process process = runtime.exec(command); process.waitFor(); ... The issue we are having is related to the way that this "child-process" is getting created on Linux (Redhat 4.4 and Centos 5.4). It's my understanding that an amount of memory equal to the amount tomcat is using needs to be free in the pool of physical (non-swap) system memory initially for this child process to be created. When we don't have enough free physical memory, we are getting this: java.io.IOException: error=12, Cannot allocate memory at java.lang.UNIXProcess.<init>(UNIXProcess.java:148) at java.lang.ProcessImpl.start(ProcessImpl.java:65) at java.lang.ProcessBuilder.start(ProcessBuilder.java:452) ... 28 more My questions are: 1) Is it possible to remove the requirement for an amount of memory equal to the parent process being free in the physical memory? I'm looking for an answer that allows me to specify how much memory the child process gets or to allow java on linux to access swap memory. 2) What are the alternatives to Runtime.getRuntime().exec() if no solution to #1 exists? I could only think of two, neither of which is very desirable. JNI (very un-desirable) or rewriting the program we are calling in java and making it it's own process that the webapp communicates with somehow. There has to be others. 3) Is there another side to this problem that I'm not seeing that could potentially fix it? Lowering the amount of memory used by tomcat is not an option. Increasing the memory on the server is always an option, but seems like more a band-aid. Servers are running java 6.
