• Is there a way to force JUnit to fail on ANY unchecked exception, even if swallowed

  - by Uri

  I am using JUnit to write some higher level tests for legacy code that does not have unit tests. Much of this code "swallows" a variety of unchecked exceptions like NullPointerExceptions (e.g., by just printing stack trace and returning null). Therefore the unit test can pass even through there is a cascade of disasters at various points in the lower level code. Is there any way to have a test fail on the first unchecked exception even if they are swallowed? The only alternative I can think of is to write a custom JUnit wrapper that redirects System.err and then analyzes the output for exceptions.

• Drupal pass argument to page

  - by stotastic

  I have a custom Drupal module displaying some data in a table. Each row has a link which if clicked will delete the relevant row. Specifically, when the link is clicked it will take the user to a confirmation page. This page is really just a drupal form which says 'are you sure' with two buttons: 'Yes', 'No'. I figure I will need to pass the rowID to the confirmation page. My question: What is the typically way to pass data to a new page in Drupal 7? I guess I could just add the rowID to the URL and use the $_GET[] from the confirmation page... I don't think this is very safe and was wondering if there was a better 'Drupal' way. Thanks!

• Recursive algorithm for coalescing / collapsing list of dates into ranges.

  - by Dycey

  Given a list of dates 12/07/2010 13/07/2010 14/07/2010 15/07/2010 12/08/2010 13/08/2010 14/08/2010 15/08/2010 19/08/2010 20/08/2010 21/08/2010 I'm looking for pointers towards a recursive pseudocode algorithm (which I can translate into a FileMaker custom function) for producing a list of ranges, i.e. 12/07/2010 to 15/07/2010, 12/08/2010 to 15/08/2010, 19/08/2010 to 20/08/2010 The list is presorted and de-deuplicated. I've tried starting from both the first value and working forwards, and the last value and working backwards but I just can't seem to get it to work. Having one of those frustrating days... It would be nice if the signature was something like CollapseDateList( dateList, separator, ellipsis ) :-)

• Looking for a mobile platform to view vector data and use it like a simple map

  - by Orchestrator

  I would like to develop or use an existing platform that will allow me to view custom vector data and use it as a map on mobile phones such as Android/IPhone (Maybe even WP7). I'm hoping that there's already a good infrastructure for what I need so I would not need to develop a whole infrastructure by myself. In Conclusion - Is there any existing platform that may answer my needs? If not, how would you guys suggest I should begin? How should I save my vector data? How could I read it? Should I view it with a graphics engine like OpenGL? Is there any chance this solution could be cross-platform? I know that it's possible since it was already done with apps like Waze. And it works the same on iOS and Android. Thanks!

• Co-opt popular abandonware opensource project? Thoughts?

  - by Mike Bouck

  Here's the scenario: A popular open source project is used/loved by many but has become stale due to the fact that the last drop came out nearly a year ago. Many bugs/feature requests/fixes have been logged in the interim and everyone is getting by via downloading the trunk and building custom/private builds with the changes incorporated. The copyright is simple -- there is none and the code is in the public domain. The project owner spins the project as community open source and has setup a sourceforge site, but to date (5 years running now) has yet to accept one contributor. In otherwords the "community" is a community of one. The project owner takes great pride in the project and has obviously contributed a lot of time/effort but for whatever reason has has seemingly abandoned the project and is unresponsive when offers of help are made. So, the question, should the community fork the codebase, setup a new community site, and take matters in their own hands?

• Drupal questions - customizing form_altered modules

  - by bert

  This week I have figured out how to modify form elements in the location module using form_alter and the custom element hook_elements() see: see http://stackoverflow.com/questions/2637052/need-some-tips-on-drupal-form-value I was able to to hide elements using unset eg: unset($element['locpick']['user_latitude']); Also added css with drupal_add_css to hide unwanted groups, and change margins, borders & padding However, I have a few questions - how can I add additional text header between fields? - how can I change input field length? - is it possible to move fields around or put them in a table? reference: http://tinyurl.com/y6ugwtd

• Which not displaying location of executible actually run.

  - by Nick

  I have a version of SVN on my system in /usr/bin/svn. This is too old to use with some repositories so I compiled a newer version in /home/user/built/bin/svn which works fine. I added this to my PATH so it should be run first. Typing which svn produces /home/user/built/bin/svn however typing svn --version reveals that it us using the old version still. if I run /home/user/built/bin/svn --version then the correct version is displayed. Since the custom version is first in my $PATH, and which lists it first why is the older version being invoked when I run svn? I thought which used your $PATH to find executables in the same fashion as the shell? [Edit] Type gives: type svn svn is hashed (/usr/bin/svn) Is this the problem?

• What is the correct way to customize Icon and Text position of items in a QListView?

  - by petermcg

  I'm using C++ and Qt's (4.6) model/view framework and wondering what is the correct way to change the display of items in a QListView or a class derived from QListView from: to: I'm not concerned about the sort order or Flow, I'm interested in the best way to correctly position the text to the right of the icon. If this can only be done by writing a custom QStyledItemDelegate that's totally fine, I want to rule out whether this is the correct approach or whether it's best to look at setLayout or similar, example code would help. The example application I'm looking at is the 'interview' example from qtdemo which amongst other things displays icons and text in a QListView.

• Which trick uses Apple to show icons in the dock contextual menu ?

  - by Matthieu Riegler

  My question is quite simple : To use a custom menu for the apps icon on the dock, - (NSMenu*) applicationDockMenu: (id) sender; of the NSApplicationDelegate has to return the menu that the dock will display. Using setImage on a NSMenuItem, you can normaly add icons to the menu. They show up on the normal menu, but not on in contextual menu of the app's dock icon. Then how did Apple manage QuickTime, XCode, Preview to show icons in the list of recent opened files accessible in their dock contextual menu ? Thx.

• How to get notified of modification in the memory in Linux

  - by Song Yuan

  In a userspace program in Linux, I get a piece of memory via allocation from the heap, then the pointer is distributed to a lot of other components running in other threads to use. I would like to get notified when the said piece of memory is modified. I can of course develop a custom userspace solution for other components to use when they try to modify the memory. The problem in my case is that these are legacy components and they can write to memory in many occasions. So I'm wondering whether there is a similar API like inotify (get notified when file is changed) or other approaches in order to get notified when a piece of memory is changed. I considered using mmap and inotify, which obviously won't work if the changes are not flushed. Any suggestions are appreciated :-)

• Do you know any build systems with decent support for parallelization?

  - by dahpgjgamgan

  Hi, I am looking for a build system (working on ms windows) that has good support for parallelization of tasks/targets (or whatever you call them). To be more specific - during build (that is initiated on MS Windows machine) I need to copy source files to a number of different machines (which are not necessarily running Windows) and start a remote job on each of them - and I really like to do that on all machines at once. Does anyone know a build system that's capable of executing such a task in parallel. From what I googled, the options currently available are: -j switch in make - but i don't know if nmake supports this -some custom nAnt tasks -msbuild has some form of support for parallelization - seems similiar to make (meaning you don't specify what to do in parallel, just specify that it would be nice to build things that way) -fake (f# make) is written in functional programming language which are known to have good parallelization support - but I'm not very skillful in functional programming area. Any other solutions I could explore?

• iPhone: InterfaceBuilder nibs disconnected from my project

  - by John Leonard

  Since upgrading to XCode 3.2, InterfaceBuilder doesn't play nice. All of my image links are broken in IB but they'll show fine when I compile. When I go to the combo box to select an image for my UIImageView, it doesn't have the image files I've added to my app. I also can't create a new .nib and associate it with a class I've written. Like images, my custom viewcontrollers aren't available to pick from. I'm going to try a reinstall but I was curious if anyone's dealt with this?

• viewForHeaderInSection - create header that would display properly in all cases

  - by sha

  I have an interesting problem/question and i'm not sure if it is even doable. So I have a custom header view for regular UITableView. But it's transparent and it doesn't fill fill table width. So it displayed properly when table is scrolled and this header view is displayed above cell content (sticked to the top). But when same header is displayed between two sections down - it looks ugly, because it's transparent and it's either displayed above black rectangle or above table background. I was wondering is there way to customize header view for when it's stick to the top and when it's not. Or... may be it's possible to specify what needs to be displayed underneath header view when it's between sections. Something like sectionSeparatorView?

• Sorting an ArrayList of Contacts

  - by Sameera0

  Ok so I have a been making an addressbook application and have pretty much finished all the key features but I am looking to implement a sort feature in the program. I want to sort an Arraylist which is of a type called Contact (contactArray) which is a separate class which contains four fields; name, home number, mobile number and address. So I was looking into using the collection sort yet am not sure how i'd implement this. Is this the right sort I should be using / is it possible to use or should I look into making a custom sort?

• Field annotated multiple times by the same attribute

  - by Jaroslaw Waliszko

  For my ASP.NET MVC application I've created custom validation attribute, and indicated that more than one instance of it can be specified for a single field or property: [AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = true)] public sealed class SomeAttribute: ValidationAttribute I've created validator for such an attribute: public class SomeValidator : DataAnnotationsModelValidator<SomeAttribute> and wire up this in the Application_Start of Global.asax DataAnnotationsModelValidatorProvider.RegisterAdapter( typeof (SomeAttribute), typeof (SomeValidator)); Finally, if I use my attribute in the desired way: [SomeAttribute(...)] //first [SomeAttribute(...)] //second public string SomeField { get; set; } when validation is executed by the framework, only first attribute instance is invoked. Second one seems to be dead. I've noticed that during each request only single validator instance is created (for the first annotation). How to solve this problem and fire all attributes?

• How can I open another tab in the browser from the Code Behind [duplicate]

  - by Daniel Powell

  This question already has an answer here: Response.Redirect to new window 18 answers I have an ASP.Net project that I am working on that involves opening another tab in the browser from the vb.net (code behind). I have tried to use the WebBrowser control to open the new tab as well as tried to use the Script manager however I have not been able to open the new tab. The button I am using is a custom button in a DevExpress GridView, and I am handling its click with this code: Private Sub ASPxGridView2_CustomButtonCallback(sender As Object, e As DevExpress.Web.ASPxGridView.ASPxGridViewCustomButtonCallbackEventArgs) Handles ASPxGridView2.CustomButtonCallback If e.ButtonID <> "customButton" Then Return End If Dim neededID = ASPxGridView2.GetRowValues(e.VisibleIndex, "target") Dim id = CStr(neededID) Dim url = ("targetPage.aspx" + "?ID=" + id) Dim wb As WebBrowser wb.Navigate(url,True) End Sub I'm not sure why this would not work, any suggestions as to how I should open a new browser tab with or without the WebBrowser works for this project. EDIT: I cannot use javascript with this ASPxGridview So I need an answer that doesn't involve modification to the javascript except through the vb.net code behind

• Android ListView Item Visibility

  - by user1478754

  I'm trying to create a screen that displays multiples items. For this, I've created a listview but I'm not sure how to approach how to add/remove items from it. Since I'm using custom listview items, I've created my own listadapter but now I need a way to add items on a button click. Is there a way to create listview that can take an indefinite amount of items (instead of passing it in an fixed length array of View objects)? Also what's the best way to remove items from listviews? setVisibility?

• Not getting image in h:graphicImage in JSF

  - by Nitesh Panchal

  Hello, I have this very strange error with h:graphicImage This code works fine :- <h:graphicImage value="/Common/Images/#{item.templatePicName}"/> And this one doesn't :- <h:graphicImage alt="${app:getCommonImagePath(item.templatePicName)}" value="${app:getCommonImagePath(item.templatePicName)}" /> It only shows alt value /Common/Images/Sunset.jpg which is perfectly fine and works in 1st case. Then why doesn't it work in 2nd case? There are no problems with my images. They are present in right directory. here getCommonImagePath is my custom EL function, whose definition is : package Common; public final class AppDeployment { private AppDeployment(){ //hide constructor } private static String commonImageFolderPath = "/Common/Images/"; public static String getCommonImagePath(String picName){ return commonImageFolderPath + picName; } }

• Protocol/Packet Design Questions

  - by cam

  I'm looking to a design a protocol for a client-server application and need some links to some resources that may help me. The big part is I'm trying to create my own "packet" format so I can minimize the amount of information being sent. I'm looking for some resources to dissect their protocol, but it seems some completely lack packet design, such as SMTP (which just sends strings terminated by CLRF). What are the advantages/disadvantages of using a system like SMTP over a system that uses a custom made packet? Couldn't SMTP use only a couple bytes to cover all commands through bit flags and save bandwidth/space? Just trying to get my head around all this.

• Int property in class definition

  - by Daniel I-S

  I have the following class structure for custom UITableViewCells: NumericEntryCell - Contains method for controlling max value that can be entered into a textbox. SliderCell - inherits from NEC and contains methods for handling slider-control of textbox value TextOnlyCell - just contains a textbox CellA - inherits from SliderCell and has a max value of 28 CellB - inherits from TextOnlyCell and has a max value of 150. I want NumericEntryCell to contain a definition for a property that contains the maxValue. I want to be able to set a value for this in the initialize method of a child class (CellA or CellB). Currently I have an int maxValue declared in the interface of NEC. I declare a property for this with @property int maxValue and @synthesize it within the .m file. However, attempting to modify this property's value from CellA or CellB's initialize method has no effect - when I hit a breakpoint in the NEC method that uses this value, its value is always zero. How can I get this to work?

• Class properties vs NSArray / NSDictionary

  - by Frank Martin

  I want a custom class object to hold data and have somehow the feeling that creating about 80 properties is not the best way of doing it. Most of the properties would be bool values, so i'm thinking about creating Arrays (keys / values) or (probably better) a NSDictionary attached to the object for holding the data. Does that make sense or should i stay with the properties? Extra: Are there general pros and cons for the different approaches? And what keywords / concepts do i have to search for to find discussions about that somehow general question? Thanks in advance

• ActionScript Parameter Filtering

  - by TheDarkIn1978

  i'm setting up a custom class that accepts some Number parameters, but i need to limit those parameters and would like to know the best way of doing so. currently, i'm simply calling if statements, and throwing an error if the number is above or below what's accepted. for example, there is a parameter that accepts and angle, but only between 0 and 90. in the case i've typed it as a uint so now i only have to check to see if it's above 90. there's also a parameter Number typed parameter that only accepts values between the range of 0.0 and 1.0. is my method of using if statements and throwing erros the usual way of filtering parameters?

• Creating WebService test harness

  - by user232337

  Hello, I am trying to create a test harness for our QA staff to test our internal web services. I would like to create a web app that will allow them to enter a uri then submit. The web app will then interrogate the uri to get the appropriate parameters expected and returns with a generated input form. I know, this would be similar to SOAPUI and others. However, I feel it would be earier for them to be able to just use a form with entry fields and click a button to invoke the service and get the results back for display in the web app. In addition, I could create some custom logic that allows them to generate specific behavior they need. Has anybody done anything like this? I have searched and have found similar functionality but nothing close enough to help me. If you need more details please let me know. Any help would be greatly appreciated. Thanks in advance! Ryan

• Localizing formatting functions instead of properties in VS.NET resources

  - by LexL

  I noticed that .NET framework uses formatting functions, generated the same way localizable string are. There is a resource file Resources.resx with resource string TestString. So you may use it in code like this: string localizableValue = Resources.TestString; Now, imagine you need a formattable localizable string, to use it in string.Format function. So everytime you use it, you have to write something like this: string localizableFormattedValue = string.Format(Resources.TestFormatString, someParam1, someParam2); The observation says that in .NET framework generated resource classes already include the above construction. So instead of string property, a string function is generated. The resulting code looks like this: string localizableFormattedValue = Resources.TestFormatString(someParam1, someParam2); The question is - how do they do this? Is it some custom Microsoft feature (resx generator) or I'm missing something obvious?
