  • Unit testing custom controls in Silverlight

    - by Hrvoje
    I have several custom controls (some kind of frames for content and layout management, like wrap panel), and would like to write unit tests for them. It's hard to find any good examples except Silverlight control toolkit, which has some helper classes to do unit tests and it's quite complicated. For MVVM classes it's easy to write tests because they don't use SL dependency system and infrastructure. Questions: how to unit test DepedenyProperty, what do I need to test how to test attached property do I test bindings with theme or UserControl, like simple textblock content binding, or command/event binding in MVVM with UserControl what else do I test in my custom controls, beside my business logic any good tutorial to achieve tests like those in control toolkit How do I start? Is SL controls toolkit only option for learning? For testing framework i'm using one from control toolkit, and for continuus integration on TFS build server I planned to use Statlight (from codeplex). Any advice on that?

  • Is there a free code coverage tool suitable for use with .NET 4 and NUnit?

    - by Damian Powell
    Is there a free code coverage tool suitable for use with .NET 4 and NUnit that runs from the command line (and is thus suitable for use on a build server)? Please note that any tools that require editions of Visual Studio higher than Professional are not appropriate in this case. I am asking this question because I can't get NCover 1.5.8 to work with NUnit 2.5.5 on a .NET 4 C# app. I can run the unit tests, and I can generate a Coverage.Xml file, but it is empty - it contains no sequence points. After a lot of research, I have concluded that this is because NCover 1.5.8 simply doesn't work with .NET 4. However, if you know better, please feel free to answer this question from another user.

  • Best practices for handling string in VC++?

    - by Hiren Gujarati
    As I am new to Visual C++, there are so many types for handling string. When I use some type and go ahead with coding but on next step, there are in-build functions that use other types & it always require to convert one type of string to other. I found so many blogs but so confused when see so many answers & try but some are working & some are not. Please give your answer or links that gives ultimate solution for handling different types of strings in visual c++.

  • Strategy for developing a multi function asp.net web application

    - by user247023
    I'm about to start a new project and want some advice on how to implement. I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out. If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules. to make things more difficult, there is some shared functionality like common users, roles and security. Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional. Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame. I can see that say, if I wanted to update the time management module, I would only need to build and release this separately, and the rest of the solution would be 'untouched' Any better alternatives?

  • rgl.snapshot() No Longer Works

    - by bill_080
    I just upgraded R and rgl to the following versions. Now, rgl.snapshot() no longer works. It worked in previous versions. Is there a way around this? R version 2.12.1 (2010-12-16) rgl version 0.92.798 > library(rgl) > x<-rnorm(100) > y<-rnorm(100) > z<-rnorm(100) > r<-0.2 > p <- plot3d(x, y, z, axes=FALSE, box=FALSE, radius=r, type='s', + xlab="", ylab="", zlab="", col=rainbow(100)) > rgl.snapshot("C:\\Temp\\pic.png", fmt="png", top=TRUE ) Error in rgl.snapshot("C:\\Temp\\pic.png") : pixmap save format not supported in this build

  • Connect 4 with neural network: evaluation of draft + further steps

    - by user89818
    I would like to build a Connect 4 engine which works using an artificial neural network - just because I'm fascinated by ANNs. I'be created the following draft of the ANN structure. Would it work? And are these connections right (even the cross ones)? Could you help me to draft up an UML class diagram for this ANN? I want to give the board representation to the ANN as its input. And the output should be the move to chose. The learning should later be done using backpropagation and the sigmoid function should be applied. The engine will play against human players. And depending on the result of the game, the weights should be adjusted then.

  • How to force a WebPart to display in all pages of a portal?

    - by Mehdi
    Hi, I'm working on a portal/CMS project and (unfortunately) build the foundation on WebParts platform. However I need to provide an option for admin to choose whether a webpart should be display in all pages or not. Finally I've found a nice article from Damon Armstrong that describes a way to store all personalization data of a group of pages into one record. Thus every changes the admin made for a webpart, affect whole pages. But it doesn't seems to be a solution for me. May be it would be solved by writing a custom personalization provider, but I don't now how. Any Ideas about the problem? Thanks

  • How do I use dependencies in a makefile without calling a target?

    - by rassie
    I'm using makefiles to convert an internal file format to an XML file which is sent to other colleagues. They would make changes to the XML file and send it back to us (Don't ask, this needs to be this way ;)). I'd like to use my makefile to update the internal files when this XML changes. So I have these rules: %.internal: $(DATAFILES) # Read changes from XML if any # Create internal representation here %.xml: %.internal # Convert to XML here Now the XML could change because of the workflow described above. But since no data files have changed, make would tell me that file.internal is up-to-date. I would like to avoid making %.internal target phony and a circular dependency on %.xml obviously doesn't work. Any other way I could force make to check for changes in the XML file and re-build %.internal?

  • progress bar in separate window

    - by Kelly
    (WPF) We have been asked to build a little window that pops up when the app is busy (instead of or in addition to a wait cursor). We put a textblock in the window, and a ProgressBar with IsIndeterminate = true. We call show on the little window, and then start up our long-running process, calling Close on the little window when we are through. However, during the long-running process, the ProgressBar does not show any activity, and the little window shows (Not Responding) in its title. Is this even possible? A better idea?

  • Client-side session timeout redirect in ASP.Net

    - by Mercury821
    I want to build a way to automatically redirect users to Timeout.aspx when their session expires due to inactivity. My application uses forms authentication and relies heavily on update panels within the same aspx page for user interaction, so I don't want to simply redirect after a page-level timer expires. For the same reason, I can't use '<meta http-equiv="refresh"/>' What I want to do is create a simple ajax web service with a method called IsSessionTimedOut(), that simply returns a boolean. I will use a javascript timer to periodically call the method, and if it returns true, then redirect to Timeout.aspx. However, I don't want calling this method to reset the session timeout timer, or the session would never time out because of the service call. Is there a clean way to avoid this catch-22? Hopefully there is an easy solution that has so far eluded me.

  • How can I enforce Eclipse to use Sun Java?

    - by Dan
    Hi Before installing Eclipse I had Open JDK on default. Now I changed it to Sun Java. I did as Eclipse Helios was running really slow, unfortunately it is still... Do you have any ideas how to enforce it to use Java Sun? I could reinstal it however I have already Android SDK installed so I would have to do all the process again, after all thats not the correct way of solving problem I think. I'm using Ubuntu 10.10. java -version java version "1.6.0_22" Java(TM) SE Runtime Environment (build1.6.0_22-b04) Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode) Would be grateful for any help. Best, Daniel

  • extension method phone format with country code as parameter

    - by frenchie
    Hi, I'm writing an extension method called ToPhoneFormat that formats a string of digits to phone numbers. Is it possible to add a parameter to the method that would enable me to call it like this: MyPhoneString.ToPhoneFormat(international code) That way, I could write MyPhoneString.ToPhoneFormat(1); to format a US phone number and MyPhoneString.ToPhoneFormat(33) to format a French phone number. I already wrote the method that does the formatting but I'm wondering how to build the constructor so that it works with a parameter when I'm calling it. Thanks.

  • How can Excel 2007 / 2010 consume a REST web service?

    - by jallen
    What options exist to consume a REST web service from within Excel 2007 / 2010? I can use XML Maps to consume a basic XML list, but that doesn't let me build a dynamic URL (so I could include parameters). For example, I can add an XML Map to Excel for http://machine/service/level/5 and display the values in the workbook just fine - no problem there. The real question is, how can I dynamically change the /5 part of the URL to come from another cell in excel? That way I can have a couple of cells that have the options (what ID, what name, etc.) and whenever those values change (ideally) a new dynamic URL would be constructed and the XML map would be refreshed. Is such a thing possible? Does anyone else have a better way to take some parameters, call a web service (REST or SOAP, I'm not picky) and shove the results back into excel for further manipulation?

  • jQuery: Animated header plugin

    - by Fverswijver
    I'm looking for a jQuery plugin that can help me with the following: I have a list of images I want to use for my header but they are pretty big (height especially) and I don't want to resize them to fit my small header div. What I'd want is a plugin that allows the images to start at the bottom of the div (or rather the top of the image at the top of the div) and move upwards so the entire image can be seen, and once up they are shown entirely (bottom of image at bottom of div) they should "blend" (opacity toggle or something alike) with the next image and thus create a continuous loop with all the images. I've looked through several plugins but have never found one that can achieve what I'm looking for (maybe I'm asking for a tad too much) but my JS is not sufficient enough to build it myself. Thanks!

  • How to integrate access control with my ORM in a .net windows form application?

    - by Ying
    I am developing a general database query tools, a .Net 3.5 Windows Form application. In order to make the presentation layer is independent of the database layer. I use an ORM framework, XPO from DevExpress. But, I have no access control function built in. I surfed Internet and I found in WCF Data Services, there is an interesting concept, Interceptor, which is following AOP(Aspect Oriented Programming). I am wondering who has such an experience to build access control in ORM. My basic requirement is : It should be a general method and controlled by users in runtime. So any hard coding is not acceptable. It could be based on attribute, database table, or even an external assembly. I am willing to buy a ready solution. According to the idea of AOP, an access control function can be integrated with existing functions easily and nearly not knowingly to the previous developer;) Any suggestions are welcome.

  • C++: Best text accumulator

    - by MInner
    Text gets accumulates piecemeal before being sent to client. Now we use own class that allocates memory for each piece as char massive. (Anyway, works like char[][] + std::list<char*>). Then we build the whole string, convert it into std::sting and then create boost::asio::streambuf using it. That's slow enough, I assume. Correct me if I'm wrong. I know, in many cases simple FILE type from stdio.h is used. How does it works? Allocates memory at every write into it. So, is it faster and is there any way to read into boost::asio::streambuf from FILE?

  • ASP.NET Forms automation/serialization/binding

    - by creo
    I need to implement many forms in ASP.NET application (for IRS mostly). There are will be a lot of standard controls for each form (textboxes, dropdowns, checkboxes, radio). And business entity assigned to each. What's the best solution to automate this process? I need to: Have layout stored in DB (in XML). Layout must support several columns, tabbed interface Automatically bind business object values to the form Automatically read form values and write to business object Must support automatic validation Some basic workflows support would be good I used to work with TFS and saw how they implemented WorkItem templates (.wit files). In general this is all I need. But what framework did they build it on? How can I utilize this solution? I know about Dynamic Data only: http://www.asp.net/dynamicdata

  • Is there a SaaS for logging user activity?

    - by JoshL
    In almost every app that I build I create some kind of user log table to log various activities that my actual USERS (not visitors, but someone with an account) perform on the site. This is primarily used for customer service issues to allow me to pull up a record of the pages and actions that a user has visited. The downside to this is the size of the UserLogs table. It gets immense. I'm not sure if it is common practice or not for others to log INDIVIDUAL (not aggregate like Google Analytics) user behavior to a database, but if it is I'm wondering if any form of a SaaS exists to help offload this task? I essentially need a RESTful API that lets me store and retrieve individual user activity quickly and securely. Anyone know of any or am I the only one who has this issue?

  • Possible to set filter on subform from parent form before subform data loads

    - by tbone
    I have frmParentForm with multiple controls used to build a filter for frmSubForm. On frmParentForm_Load, I am doing (simplified example): Me.sbfInvoice_List.Form.filter = "[created_on] >= #" & Me.RecentOrderDateCutoff & "#" Me.sbfInvoice_List.Form.FilterOn = True The problem is, on initial load, it seems the subform load is occurring first, so the entire table is loaded. Is there a way (in a different event perhaps) to properly set the subform filter from the parent form so it is applied before the subform does its initial data load? (The subform can exist on its own, or as a child of many different parent forms (sometimes filtered, sometimes not), so I'd rather not put some complicated hack in the subform itself to accomplish this.)

Cannot insert duplicate key in object 'dbo.Clients'. The statement has been terminated. The Primary key ClientId field is not an identity column and therefore requires filling To date I have the following insert into Clients( ClientID, Title, Forenames, FamilyName, [Address], Town, County, PostCode, PhoneNumber, StartDate) SELECT ( Select Max(Clients.ClientID)+ 1, SRCServiceUsers.Title, SRCServiceUsers.[First Names], SRCServiceUsers.Surname, --BUILD UP MUITIPLE COLUMNS SRCServiceUsers.[Property Name] + ', ' + SRCServiceUsers.Street + ', ' + SRCServiceUsers.Suburb as [Address], SRCServiceUsers.Town, SRCServiceUsers.County, SRCServiceUsers.Postcode, SRCServiceUsers.Telephone, SRCServiceUsers.[Start Date] From srcsERVICEuSERS How can i autoincrement the PK field - CLientID when inserting the data?

  • Clean way to combine multiple jars? Preferably using ant

    - by Jacob
    I have runtime dependencies on some external jars that I would like to "rejar" into a single jar. These external dependencies are stored in a external_jars directory, and I'd like to be able to not have to list each one out (e.g., to not need to change my build scripts if my dependencies change). Any thoughts? Google gave me a good answer on how to do this if you don't mind listing out each jar you want as a dependency: http://markmail.org/message/zijbwm46maxzzoo5 Roughly, I want something along the lines of the following, which would combine all jars in lib into out.jar (with some sane overwrite rules). jar -combine -out out.jar -in lib/*.jar

  • NET Framework Validation Library

    - by Kane
    As I see it most applications have a requirement for some form of validation and a number of fantastic free offerings are available (I.E., Fluent Validation, Validation Block, Spring, Castle Windsor, etc). My question is why does the .NET Framework not include any inbuilt validation libraries? I am aware the .NET Framework allows a developer the ability to build their own validation libraries/methods/etc. and anything provided as part of the .NET Framework would not always meet everyone’s needs. But surely something could have been included? ASP.NET has a minimal set of validators but these have not really been extended since .NET 2.0 was released.

  • What is my problem with ASP.NET pubslishing?

    - by Shankarooni
    I am done testing my site and I want to upload it to a site like this http://www.university.edu/mydepartment/myname the admin told me the server runs on .NET 3.5. So i used Linq ... now i tried to upload the site by two ways: when i just copy everything (with modification of web.config database settings) i get an error: CS0246: The type or namespace name 'DataClassesDataContext' could not be found (are you missing a using directive or an assembly reference?) Version Information: Microsoft .NET Framework Version:2.0.50727.3082; ASP.NET Version:2.0.50727.3082 Note here it says version 2.0 did he just lie to me? or its my configuration mistake? anyway, i added the reference, nothing changes. I tried also publishing (Build, publish) with option to keep the pre-comiled site updatable, and I get one line saying: this is a makefile and should be deleted! what is going on?

  • Has anyone managed to get Visual Studio 2003 running on Windows 7?

    - by Jeremy White
    Yes, I know... I could set up a virtual machine running XP. Unfortunately our build environment is such that we need to be running VC2003, 2005 and 2008 concurrently and it would be much more convenient if I could run 2003 natively on Windows 7 for the few projects we have that require it. I realize some things may not be available in the IDE, but I was able to run 2003 under windows Vista and if I could get the same base level of functionality under Windows 7 I would be extremely happy. Right now I get an error opening the *.pdb file when I compile after switching vc2003 to run as Administrator under compatibility mode for XP SP 2. Thanks!

  • Autocomplete with Django, jQuery and google app engine

    - by Ron
    Hey guys, I'm new to Django and jQuery, but I have a lot of python experience. I'm basically trying to write an HTML form, with one text box for now, that as you type in it, shows you auto completion options. this will be used for finding restaurants, and I intend to use the Yelp API for that. can someone please point me out in a direction of a tutorial on how to do this - specifically with regards to the Django / HTML / jQuery rather than how to work with the Yelp API? Are there any tutorials I should read? All tutorials I have found are very basic ones that build forms from the Django data models.. Thanks!
