  • Scriptaculous Autocomplete to activate when the page is loaded.

    - by Jelle
    Is there a way to fire up Scriptaculous's Autocomplete to search with the default word from the inputfield when the page is loaded? Something like this? <input type="text" id="autocomplete" class="autocomplete_input" name="autocomplete_parameter" value="friends"/> <span id="indicator1" style="display: none"> loading </span> <div id="autocomplete_choices" class="autocomplete"> </div> <script type="text/javascript"> function AutoComp() { var myAutoCompleter = new Ajax.Autocompleter("autocomplete", "autocomplete_choices", "url", {indicator: 'indicator1',}); } document.onLoad = AutoComp.activate(); </script>

  • How can I use my multiple cored dedicated server to run my java application?

    - by Delta
    I have a game built in a java environment and I use JVM. I have 4 cores @ 2.4Ghz and my server is only using one of those cores... I've tried and searched and I still have no guides to setup multiple cores to run the game like, say 1 core for running the character saving + loading, and 1 core for the server itself, and 1 core for a helper to help other cores that need more power. I don't even know if this is possible but this is all in java the operating machine is windows server 2003 and I've tried so hard I just don't know what to do. May someone please help me! Thank you so much!

  • "autotest/rails [...] doesn't [...] exist. Aborting"

    - by Ethan
    I'm finding that autotest has stopped working... $ autotest loading autotest/rails Autotest style autotest/rails doesn't seem to exist. Aborting. According to this blog post, the common reason for this error is that people don't have the autotest-rails gem installed. However, I definitely have that installed: autotest-rails (4.1.0) ZenTest (4.1.4, 4.1.3, 4.1.1, 4.0.0, 3.11.1, 3.11.0, 3.10.0, 3.9.3, 3.9.2) I haven't installed any new gems today or yesterday, though I might have done a gem update yesterday. Another issue I saw mentioned was incompatibility with Ruby 1.9, but I'm using MRI Ruby 1.8.6.

  • How to partially update views in an app widget without rebuilding all the RemoteViews

    - by Gianni Costanzi
    I'm implementing an app widget and I'd like to be able to change the property of a single view in the widget layout, without rebuilding all the RemoteViews from scratch, which involves loading XML etc and which is not necessary in some circumstances.. Is there a way to say "update property X on view identified by a specific ID in the current widget layout"? I've seen that there is a partiallyUpdateAppWidget method in the AppWidgetManager class but I can't understand nor if it is meant for this purpose neither how it must be used.. Can you help me or point me to a useful link or example?

  • Can't check more than one RadioButton across multiple items in a Treeview

    - by Mike Johnston
    I’m using a TreeView control to present a list of Questions. Using the Prism.DataTemplateSelector, I'm loading a View (.xaml file) that represents a single Question into each node in the TreeView. In the View for that question is a ListBox containing RadioButtons (one for each item in a Picklist object that the ListBox is bound to). The radio buttons work as expected for the question, but when I check a RadioButton on another node/question in the TreeView, the check for the button in the Question I was editing before disappears. In other words, I'm only able to check one RadioButton in the whole list of Questions/Items bound to the containing TreeView. How do I group the RadioButtons in the ListBox to the scope of the single question instead of all the questions in the TreeView.

  • UIWebView loads a local file for a long time

    - by Knodel
    I have a UIWebView which loads .rtfd.zip files like this: -(void)viewWillAppear:(BOOL)animated { self.title=@"Title"; if(rowPosledovatelnosti==0) { [self loadFile:@"PosledovatelnostiObzie.rtfd.zip"]; } if(rowPosledovatelnosti==1) { [self loadFile:@"Arifmeticheskaya.rtfd.zip"]; } if(rowPosledovatelnosti==2) { [self loadFile:@"Svojstva_Arifmeticheskoj.rtfd.zip"]; } if(rowPosledovatelnosti==3) { [self loadFile:@"Geometricheskaya.rtfd.zip"]; } if(rowPosledovatelnosti==4) { [self loadFile:@"Predel_Posledovatelnosti.rtfd.zip"]; } if(rowPosledovatelnosti==5) { [self loadFile:@"Summa_Geometricheskoy.rtfd.zip"]; } } But on the device it takes some time for the UIWebView to load the content. Is there any way to optimize the loading time?

  • Dependency Injection with @Inject in Weld (JSR-299 RI). How is the corresponding @Produces found?

    - by Thorbjørn Ravn Andersen
    I have played with the JSR-299 Reference Implementation "Weld" with the purpose of using it in a stand-alone application, and I have had a look at the documentation, and marveled at the magic. My question is how the producer of a given object to be @Inject'ed is found? Either the java compiler produces hints for annotations which is easily found by the classloader, or the complete classpath must be traversed loading all classes to see what they do which sounds highly inefficient to me, or it is a completely different approach. What is the trick?

  • C# - Hiding ListViewItem based on a filter

    - by fonix232
    I want to hide some items based on a text filter in a ListView. Basically the listview loads the items from a text file, and I don't want it to be read and/or written when the user searches the list. The search is done in a combobox's KeyDown event, but there is no "Visible" property of the ListViewItem. Is there any easy way to do this, WITHOUT re-reading the file? (as it is an XML file, and it could even contain thousands of items, it would be hard to search efficiently and even let the user use the application, as the search would take for minutes (mostly with the loading)).

  • Disable animation when moving CALayers

    - by Sean Clark Hess
    The following code animates the movement, even though I didn't use beginAnimations:context. How do I get it to move without animating? This is a new iphone view project, and these are the only updates to it. // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; sublayer = [CALayer new]; sublayer.backgroundColor = [[UIColor redColor] CGColor]; sublayer.frame = CGRectMake(0, 0, 100, 100); [self.view.layer addSublayer:sublayer]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { sublayer.position = [[touches anyObject] locationInView:self.view]; }

  • How to block the UI during asynchronous operations in WPF

    - by mcintyre321
    We have a WPF app (actually a VSTO WPF app). On certain controls there are multiple elements which, when clicked, load data from a web service and update the UI. Right now, we carry out these web requests synchronously, blocking the UI thread until the response comes back. This prevents the user clicking around the app while the data is loading, potentially putting it into an invalid state to handle the data when it is returned. Of course the app becomes unresponsive if the request takes a long time. Ideally, we'd like to have the cancel button active during this time, but nothing else. Is there a clever way of doing this, or will we have to switch the requests to execute asynchronously using backgroundworker and write something that disables all the controls apart from the cancel button while a request is in progress?

  • String concatenation produces incorrect output in Python?

    - by Brian
    I have this code: filenames=["file1","FILE2","file3","fiLe4"] def alignfilenames(): #build a string that can be used to add labels to the R variables. #format goal: suffixes=c(".fileA",".fileB") filestring='suffixes=c(".' for filename in filenames: filestring=filestring+str(filename)+'",".' print filestring[:-3] #now delete the extra characters filestring=filestring[-1:-4] filestring=filestring+')' print "New String" print str(filestring) alignfilenames() I'm trying to get the string variable to look like this format: suffixes=c(".fileA",".fileB".....) but adding on the final parenthesis is not working. When I run this code as is, I get: suffixes=c(".file1",".FILE2",".file3",".fiLe4" New String ) Any idea what's going on or how to fix it?

  • Need help with video streaming with web-embedded Windows Media Player Component

    - by Ron
    Hello, I need to be able to play a .wmv video in a Windows Media Player component on a web page starting at a particular specified point in the video right away. I can embed the component and play the video. The problem is that even if I specify the location with The PARAM “currentPosition”, the video starts to play from the beginning. This appears to be because the requested position in the video has not been loaded yet. If I wait until the video has been loaded to the requested position and refresh the page, it will then play from the requested position. It seems that the video must start loading from the requested position in order to start right away. If this is the correct way, how would I go about doing it? If it is not, what is the proper way to do it? It can obviously be done, because YouTube’s players work like this. Thank you,

  • How to marshal structs with unknown length string fields in C#

    - by Ofir
    Hi all, I get an array of bytes, I need to unmarshal it to C# struct. I know the type of the struct, it has some strings fields. The strings in the byte array appears as so: two first bytes are the length of the string, then the string itself. I don;t know the length of the strings. I do know that its Unicode! [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)] public class User { int Id;//should be 1 String UserName;//should be OFIR String FullName;//should be OFIR } the byte array looks like so: 00,00,01,00, 00,00,08,00, 4F,00,46,00,49,00,52,00, 00,00,08,00, 4F,00,46,00,49,00,52,00, I also found this link with same problem unsolved: loading binary data into a structure Thank you all, Ofir

  • How to implement arrays in an interpreter?

    - by Ray
    I have managed to write several interpreters including Tokenizing Parsing, including more complicated expressions such as ((x+y)*z)/2 Building bytecode from syntax trees Actual bytecode execution What I didn't manage: Implementation of dictionaries/lists/arrays. I always got stuck with getting multiple values into one variable. My value structure (used for all values passed around, including variables) looks like this, for example: class Value { public: ValueType type; int integerValue; string stringValue; } Works fine with integers and strings, but how could I implement arrays? (From now on with array I mean arrays in my experimental language, not in C++) How can I fit the array concept into the Value class above? Is it possible? How should I make arrays able to be passed around just as you could pass around integers and strings in my language, using the class above? Accessing array elements or memory allocation wouldn't be the problem, I just don't know how to store them.

  • show definition (browse) in *.pdb of *.dll file

    - by ala
    I have built a Library project (DLL) in .NET. And sometimes I use the DLL along with its PDB file as a reference in some other projects. Now in the new project, I cant browse through the code of the DLL to debug. I can only see the definitions of class/methods/variables. That's by using "show definition" by browsing through the "class view" However, only in case of an exception I the contents of the DLL opens and I could see the entire code of the DLL from the new project. How could I see the contents (code) of the DLL before an exception occur?

  • NHibernate Named Query Parameter Numbering @p1 @p2 etc

    - by IanT8
    A colleague recently ran into a problem where he was passing in a single date parameter to a named query. In the query, the parameter was being used twice, once in an expression and once in a GROUP BY clause. Much to our surprise, we discovered that NHibernate used two variables and sent the single named parameter in twice, as @p1 and @p2. This behaviour caused SQL to fail the query, with the usual "a column in the select clause is not in the group by clause" (I paraphrase ofcourse). Is this behaviour normal? Can it be changed? Seems to me that if you have a parameter name like :startDate, NHibernate only needs to pass in @p1 no matter how many times you might refer to :startDate in the query. Any comments? The problem was worked around by using another sub-query to overcome the SQL parsing error.

  • Passing a variable to jsp when reloading an iframe using javascript

    - by Vee
    In my javascript code I load a jsp page in an iframe and pass some variables like this: htmlData[i++]="<iframe id=\"mapframe\" frameborder=\"0\" style=\"width:330px;height:300px\" src=\"" + "mapURL.jsp" +"&lat=" + AjxStringUtil.urlComponentEncode("33.65") +"&lng=" + AjxStringUtil.urlComponentEncode("-84.42") +"&accord=" + AjxStringUtil.urlComponentEncode(accord) +"\"></iframe>"; Then I have to reload that jsp page after an action, and I do this: accord = ui.newHeader.text(); document.getElementById('mapframe').contentWindow.location.reload(); The reload works except that the "accord" variable is not getting updated. When I call it from the jsp, it still has its original value. How do I pass the new value when reloading the iframe/jsp? It shouldn't make any difference, but I am working with jquery and this is for a Yahoo zimlet. Thanks.

  • Where to open sessions in a Spring/Hibernate stack?

    - by CaptainAwesomePants
    I'm trying to figure out a good design for a Spring/Hibernate app. When creating such an app, it appears like there are a handful of major decisions. The first major decision seems to be where to put the session/transaction boundary. It seems like I have 3 major choices: as a filter before controllers are even invoked, immediately below the controllers at the service call level, and stuffed way below the business level in repository calls. It seems to me like the right call is the middle path, but I'm not sure. I don't want my transactions open too long, but at the same time, I don't want to constantly worry about detached objects and lazy loading in the business logic. Still, there are some downsides. For instance, it makes it hard for the business logic to make a remote call without holding up a transaction for a few seconds. I wonder if there's a better way?

  • How to best deal with photos passed to IFilter?

    - by sharptooth
    I'm implementing an IFilter for indexing image formats. One problem is photos - many users have tons of photos, photos are huge and loading and searching for text on them is time consuming. Yes, sometimes people use cameras instead of scanners for digitizing documents, but the potential problems IMO far outweight the possibility of encountering a document digitized with a photo camera. So my implementation will not extract text from photos at all. What should the IFilter do once it detects that a given file is a photo image - indicate an error or return empty text?

  • Immutable Dot Net strings

    - by klork
    I usually define my string variables in vb.net as Dim f_sName as string=String.Empty f_sName = "foo" Given the immutable nature of strings in .net, is there a better way to initialize strings and deal with the "Variable 'f_sName ' is used before it has been assigned a value. A null reference exception could result at runtime." warning? Also for classes that do not have constructors which accept no arguments such as System.Net.Sockets.NetworkStream, what is the best way to define and initialize a variable of that type? All comments are highly appreciated. Thanks

  • In Prism (CAL), how can I RegisterPresenterWithRegion instead of RegisterViewWithRegion

    - by Edward Tanguay
    I have a module in a Prism application and in its initialize method I want to register a presenter instead of a view with a region, i.e. I want to do this: PSEUDO-CODE: regionManager.RegisterPresenterWithRegion( "MainRegion", typeof(Presenters.EditCustomerPresenter)); instead of loading a view like this: regionManager.RegisterViewWithRegion( "MainRegion", typeof(Views.EditCustomerView)); The presenter would of course bring along its own view and ultimately register this view in the region, but it would allow me to bind the presenter to the view in the presenter's constructor instead of binding the two together in XAML (which is more of a decoupled MVVM pattern which I want to avoid here). How can I add a Presenter to a Region instead of a view? namespace Client.Modules.CustomerModule { [Module(ModuleName = "CustomerModule")] public class CustomerModule : IModule { private readonly IRegionManager regionManager; public CustomerModule(IRegionManager regionManager) { this.regionManager = regionManager; } public void Initialize() { regionManager.RegisterViewWithRegion("MainRegion", typeof(Views.EditCustomerView)); } } }
