• url link in bibtex

  - by Tim

  Hi, I was wondering how to make a url link appear in Bibliography? For example, @misc{libsvm, abstract = {LIBSVM is an implbmentation of Support vector machine (SVM).}, author = {Chang, Chih-Chung}, keywords = {svm}, posted-at = {2010-04-08 00:05:04}, priority = {2}, title = {LIBSVM}, url = "http://www.csie.ntu.edu.tw/~cjlin/libsvm/", year = {2008} } will appear in Bibliography as [2] Chih-Chung Chang. Libsvm, 2008. But I hope the link "http://www.csie.ntu.edu.tw/~cjlin/libsvm/" could appear and the "Libsvm" could be all capital "LIBSVM". Honestly, I have no idea how a link should appear in Bibliography. What I think might be not professional. Please advise me how to put it in a professional way. Thanks and regards!

• VB.NET GroupBy LINQ statement

  - by Jason

  I am having a bear of a time getting this to work. I have a List(Of MyItem) called Items that have a OrderId property on them. From those items, I want to create a list of Orders. Some items will have the same OrderId so I want to try to group by OrderId. I then want to sort by date. Here's what I have so far: Public ReadOnly Property AllOrders() As List(Of Order) Get Return Items.Select(Function(i As MyItem) New Order(i.OrderID)) _ .GroupBy(Function(o As Order) New Order(o.OrderID)) _ .OrderBy(Function(o As Order) o.DateOrdered).ToList End Get End Property This, of course, doesn't compile, and I get the error: Value of type 'System.Collections.Generic.List(Of System.Linq.IGrouping(Of Order, Order))' cannot be converted to 'System.Collections.Generic.List(Of Order))' I've bolded the part where I think the problem is, but I have no idea how to fix it. Also, it used to work fine (except there were duplicate values) before I added the .GroupBy statement. Anyone have any ideas? Thanks

• django-rest-framework: api versioning

  - by w--

  so googling around it appears that the general consensus is that embedding version numbers in REST URIs is a bad practice and a bad idea. even on SO there are strong proponents supporting this. e.g. Best practices for API versioning? My question is about how to accomplish the proposed solution of using the accept header / content negotiation in the django-rest-framework to accomplish this. It looks like content negotiation in the framework, http://django-rest-framework.org/api-guide/content-negotiation.html is already configured to automatically return intended values based on accepted MIME types. If I start using the Accept header for custom types, I'll lose this benefit of the framework. Is there a better way to accomplish this in the framework?

• What to put as the Provider for a mocked IQueryable

  - by Vaccano

  I am working with Moles and mocking a System.Data.Linq.Table. I got it constructing fine, but when I use it, it wants IQueryable.Provider to be mocked (moled) as well. I just want it to use normal Linq To Objects. Any idea what that would be? Here is the syntax I can use: MTable<User> userTable = new System.Data.Linq.Moles.MTable<User>(); userTable.Bind(new List<User> { UserObjectHelper.TestUser() }); // this is the line that needs help MolesDelegates.Func<IQueryProvider> provider = //Insert provider here! ^ userTable.ProviderSystemLinqIQueryableget = provider | | | what can I put here? ----------------------------------------+

• Xcode Error: "Buildfile: build.xml does not exist! Build failed"

  - by user313574

  I am trying to use Xcode 3.2 for java tool development. My project has no problem building and shows it built the file build.xml fine and also shows up in file folder fine. When I try to run the .java file, I get the error: "Buildfile: build.xml does not exist! Build failed". Running "ant -find build.xml" in Terminal produces "not found". I believe the problem is that I need to point to my own build.xml location, but I have no idea how to change which directory it looks for this file. Any help is greatly appreciated. -nick Mac OS 10.6, Xcode 3.2.1 - method to create app: OrganizerNew from templateJava Tool

• BAD_UID error while exporting key in CryptoAPI

  - by mindthief

  Hi all, I am writing a test application for Microsoft CryptoAPI. I want to export the secret key of one party using the public key of the second party, and then import that secret key as the second party's secret key (this sets up a shared secret key for communication). Here is my code: if(!CryptExportKey(encryptT->hSymKey, decryptT->hPubKey, SIMPLEBLOB, 0, keyExBuf, &bufLen)) { FormattedDebugPrint(NULL, GetLastError(), "could not export secret key", TRUE); return -1; } if(!CryptImportKey(decryptT->hCryptProv, keyExBuf, bufLen, decryptT->hPubKey, 0, &(decryptT->hSymKey))) { FormattedDebugPrint(NULL, GetLastError(), "could not import secret key", TRUE); return -1; } And this gives the error: 80090001: Bad UID. The public keypair is being generated for both encryptT and decryptT (sender, receiver) by calling: CryptGenKey(encryptT->hCryptProv, CALG_RSA_KEYX, CRYPT_EXPORTABLE, &(encryptT->hPubKey)) Any idea what could be causing the error? Thanks,

• Issue passing NSMutableDictionary to a method

  - by roswell

  Hello all, I've got a chunk of code that's passing an NSMutableDictionary (amongst other things) to a method in another class: [self.shuttle makeAPICallAndReturnResultsUsingMode:@"login" module:@"login" query:credentials]; The NSMutableArray credentials is previously defined like this: NSMutableDictionary *credentials = [[NSMutableDictionary alloc] init]; [credentials setObject:username forKey:@"username"]; [credentials setObject:password forKey:@"password"]; The method that receives it looks like this: -(id)makeAPICallAndReturnResultsUsingMode:(NSString *)mode module:(NSString *)module query:(NSMutableDictionary *)query The code works fine up until this point within the above method: [query setObject:self.sessionID forKey:@"session_id"]; At this point, the application terminates -- the console informs me of this exception: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[NSCFDictionary setObject:forKey:]: method sent to an uninitialized mutable dictionary object' This leads me to believe that I must initialize NSMutableDictionary in some way in my new method before I can access it, but I have no idea how. Any advice?

• Ant trouble with environment variables on Ubuntu

  - by Inaimathi

  Having some trouble with with ant reading environment variables in Ubuntu 9.10. Specifically, the build tasks my company uses has a token like ${env.CATALINA_HOME] in the main build.xml. I set CATALINA_HOME to the correct value in /etc/environment, ~/.pam_environment and (just to be safe) my .bashrc. I can see the correct value when I run printenv from bash, or when I eval (getenv "CATALINA_HOME") in emacs. Ant refuses to build to the correct directory though; instead I get a folder named ${env.CATALINA_HOME} in the same directory as my build.xml. Any idea what's happening there, and/or how to fix it?

• Reference custom list form fields from code behind and automatically fill them with values.

  - by Janis Veinbergs

  Hello. I`v made my custom NewForm.aspx for my list and I want to add some custom code to it. So I inherit that form from my own class: public class MyCustomNewForm : Microsoft.SharePoint.WebPartPages.WebPartPage Now I want to reference some of available fields to automatically fill them for user. (Javascript won't help here as I have to get some data from other lists). But I have no idea how do I reference these fields from codebehind files. The code for control field is written (well, it was generated by Sharepoint Designer when using command Insert SharePoint Controls Custom List Form...) in .aspx page like this: <SharePoint:FormField runat="server" id="ff1{$Pos}" ControlMode="New" FieldName="Title" __designer:bind="{ddwrt:DataBind('i',concat('ff1',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Title')}"/> When looking at id at runtime, it is insanely long So how do i reference fields, so I could set Text property on them in my codebehind file?

• Hidden Features of MXML

  - by Ole Jak

  What are some of the hidden features of MXML? MXML being used in Flex Framework became quite popular language (because Flash Player is something every PC has and Flash Builder, Flash Catalist are quite popular Adobe programms) So at least from the existing features, do you know any that are not well known but very useful. Of course, this question is along the lines of: Hidden Features of ActionScript Hidden Features of JavaScript Hidden Features of CSS Hidden Features of C# Hidden Features of VB.NET Hidden Features of Java Hidden Features of ASP.NET Hidden Features of Python Hidden Features of TextPad Hidden Features of Eclipse Hidden Features of HTML Please specify one feature per answer. Note that it's not always a great idea to use these hidden features; often times they are surprising and confusing to others reading your code.

• UIImage created from CGImageRef fails with UIImagePNGRepresentation

  - by Ari J.R.

  I'm using the following code to crop and create a new UIImage out of a bigger one. I've isolated the issue to be with the function CGImageCreateWithImageInRect() which seem to not set some CGImage property the way I want. :-) The problem is that a call to function UIImagePNGRepresentation() fails returning a nil. CGImageRef origRef = [stillView.image CGImage]; CGImageRef cgCrop = CGImageCreateWithImageInRect( origRef, theRect); UIImage *imgCrop = [UIImage imageWithCGImage:cgCrop]; ... NSData *data = UIImagePNGRepresentation ( imgCrop); -- libpng error: No IDATs written into file Any idea what might wrong or alternative for cropping a rect out of UIImage? Many thanks!

• Edit dialog, with bindings and OK/Cancel in WPF

  - by Erik

  How can i have a dialog for editing the properties of a class with binding, and have OK-Cancel in the dialog? My first idea was this: public partial class EditServerDialog : Window { private NewsServer _newsServer; public EditServerDialog(NewsServer newsServer) { InitializeComponent(); this.DataContext = (_newsServer = newsServer).Clone(); } private void ButtonClick(object sender, RoutedEventArgs e) { switch (((Button)e.OriginalSource).Content.ToString()) { case "OK": _newsServer = (NewsServer)this.DataContext; this.Close(); break; case "Cancel": this.Close(); break; } } } When in the switch, case "OK", the DataContext contains the correct information, but the originally passed NewsServer instance does not change.

  I am using the following markup in WPF: <StackPanel.Triggers> <EventTrigger RoutedEvent="RadioButton.Checked" SourceName="xmlRadioButton"> <EventTrigger.Actions> <BeginStoryboard Storyboard="{StaticResource ShowXmlPanel}"/> </EventTrigger.Actions> </EventTrigger> <EventTrigger RoutedEvent="RadioButton.Checked" SourceName="adiRadioButton"> <EventTrigger.Actions> <BeginStoryboard Storyboard="{StaticResource ShowAdiPanel}"/> </EventTrigger.Actions> </EventTrigger> </StackPanel.Triggers> Though this works fine when I run the code, I get the following error in the designer window of VS 2008: Value 'RadioButton.Checked' cannot be assigned to property 'RoutedEvent'.

• LicenseException for Xceed DataGrid for WPF

  - by ewall

  I have developed a simple DB-editing app using Xceed's excellent DataGrid for WPF (UX Edition version 3.7), which is now ready for deployment... except that when I run it on a machine other than the development one where it was built, I am getting the runtime exception for invalid licensing. I have included my license key in the App.xaml.cs exactly as specified in the Xceed docs, like so: public partial class App : System.Windows.Application { protected override void OnStartup(StartupEventArgs e) { Xceed.Wpf.DataGrid.Licenser.LicenseKey = "DGF37-xxxxx-xxxxx-xxxx"; base.OnStartup(e); } } The correct version of the DataGrid DLLs are being included in the setup and the application's program directory, and there are no other versions on the target machine. Debugging doesn't show me anything useful other than the LicenseException that is thrown when the code tries to use the DataGrid, with the message that reads "Xceed.Wpf.DataGrid.Licenser.LicenseKey property must be set to a valid license key in the code of your application before using this product..." Any idea what's going wrong here?

• Split NSData objects into other NSData objects with a given size

  - by Cedric Vandendriessche

  I'm having an NSData object of approximately 1000kb big. Now I want to transfer this via bluetooth. This would be better if I have let's say 10 objects of 100kb. It comes to mind that I should use the -subdataWithRange: method of NSData. I haven't really worked with NSRange. Well I know how it works, but then to read from a given location with the length: 'to end of file'... I've no idea how to do that. Some code on how to split this into multiple 100kb NSData objects would really help me out here. (it probably involves the length method to see how many objects should be made..?) Thank you in advance.

• How to access the Principal from a Java service object without using FlexContext?

  - by Marplesoft

  We're building some Java objects that are exposed via BlazeDS to our flex client application. So basically the BlazeDS messagebroker servlet instantiates and invokes methods on these objects in response to client requests. Works great. We're using app server-based authentication and have set up a security constraint on the <destination> elements in the remoting-config.xml file element to prevent unauthenticated clients from being able to access these remote java objects. Again, works fine. However, there are several places within the implementation of these java objects where we want to get the currently logged on user's username. Right now we are doing this via FlexContext.getUserPrincipal(), which gives access to this but we have a nagging concern that we don't like the idea that the implementation of these objects (the service layer) has a hard dependency on a BlazeDS class. But we're not sure how else to get access to this. The same applies to accessing the ServletContext and such. Any ideas?

• Close PrintPreviewDialog when ESC is pressed

  - by Emerick Rogul

  I'm working on a WinForms application that uses System.Windows.Forms.PrintPreviewDialog to display a Print Preview dialog. When the user presses ESC in that dialog, I'd like to close the dialog. Unfortunately, I can't figure out how to do this. I've tried to install a KeyDown/PreviewKeyDown event handler, but it never gets called. I also tried setting focus to the dialog (and to its PrintPreviewControl), thinking that was the issue, but that didn't help either. Does anyone have any idea how to make this work?

• Core Animation not working on Leopard, working on Snow Leopard

  - by Nick Paulson

  Hi, I animate NSImageViews using its animator proxy. While testing my application on Snow Leopard, everything works as expected. However, on Leopard, none of the animations are functioning. In addition, NSImageViews don't seem to take into effect the alphaValue I set on them, whether through the animator proxy or not. The only way I can get them to disappear is by setting their image to nil. What is weird is that this all works fine in Snow Leopard, but does not work on Leopard 10.5.8. Any idea on why this may be occurring?

• Resharper and Custom Live Template Not Working

  - by Bryce Fischer

  Working with Unity, I thought it would be a good idea to create some LiveTemplates to help out with creating configuration entries. For example, I want to create some typeAlias elements in a file called "unity.config": <typeAlias alias="QueryService" type="type,QueryAssembly"/> So, I created a live template: Shortcut: typeAlias Available "in all files" <typeAlias alias="$ALIAS$" type="$TYPE$,$ASSEMBLY$"/> the unity.config file is an XML file. I put the cursor in an empty spot and type "typeAlias" and then the tab key. Nothing happens. Any ideas?
