• How can I set initial values when using Silverlight DataForm and .Net RIA Services DomainDataSource?

  - by TheDuke

  I'm experimenting with .Net RIA and Silverlight, I have a few of related entities; Client, Project and Job, a Client has many Projects, and a Project has many Jobs. In the Silverlight app, I'm uisng a DomainDataSource, and DataForm controls to perform the CRUD operations. When a Client is selected a list of projects appears, at which point the user can add a new project for that client. I'd like to be able to fill in the value for client automatically, but there doesn't seem to be any way to do that, while there is an AddingNewItem event on the DataForm control, it seems to fire before the DataForm has an instance of the new object and I'm not sure trawling through the ChangeSet from the DomainDataSource SubmittingChanges event is the best way to do this. I would of thought this would of been an obvious feature... anyone know the best way to achieve this functionality?

• Method 'SingleOrDefault' not supported by Linq to Entities

  - by user300992

  I read other posts on similar problem on using SingleOfDefault on Linq-To-Entity, some suggested using "First()" and some others suggested using "Extension" method to implement the Single(). This code throws exception: Movie movie = (from a in movies where a.MovieID == '12345' select a).SingleOrDefault(); If I convert the object query to a List using .ToList(), "SingleOrDefault()" actually works perfectly without throwing any error. My question is: Is it not good to convert to List? Is it going to be performance issue for more complicated queries? What does it get translated in SQL? Movie movie = (from a in movies.ToList() where a.MovieID == '12345' select a).SingleOrDefault();

• C# - Recursive / Reflection Property Values

  - by tyndall

  What is the best way to go about this in C#? string propPath = "ShippingInfo.Address.Street"; I'll have a property path like the one above read from a mapping file. I need to be able to ask the Order object what the value of the code below will be. this.ShippingInfo.Address.Street Balancing performance with elegance. All object graph relationships should be one-to-one. Part 2: how hard would it be to add in the capability for it to grab the first one if its a List< or something like it.

• libevent, windows and .NET programming

  - by Chris

  I experiment with a lot of open source software and I've noticed a fair amount of server type applications in the open source world use libevent to facilitate event-based processing rather than spawn multiple threads to handle requests. I also do a lot of .NET programming (it's my core job function), and I'm interested in learning how libevent relates to the .NET event model. Are events in .NET the equivalent of libevent for C programs? Should I try to learn libevent and attempt to use it in custom .NET server applications or is using the standard .NET event model basically the same thing?

• What do I need to know before accepting a contract position in the United States?

  - by Andrew

  I just received an initial job offer for a contract position as a PHP developer. I have never had a contract position before, so I don't know what the implications of this are, and how it differs from a salaried position with benefits. =/ What are some things that I should be aware of before accepting the contract position? (i.e. taxes, wages, benefits, etc) It also mentions that I will sign a "day-to-day contract". What does that mean? Resources Here are some links that I've collected so far: First timer's guide to contracting - Covers contracting in the U.K., but not the U.S. The contract employee's handbook - Talks about the differences between a "Contract Employee" and an "Independent Contractor"

• Erlang: 2 database on 2 webserver ??

  - by xRobot

  I have created a blogging system with php+postgresql. Now I want to add a web chat ( in REAL TIME for Million of users simultaneously ) where every message is saved in database. I am thinking to use Erlang+Mnesia on a different webserver for this issue. Message's table will be like this: message_id, user_id, message, date user_id should be related with users table in Postgresql database in another webserver. How can I do that without lose performance ? If you have any other creative solutions tell me please ;).

• Silverlight local storage

  - by IMHO

  As you may know Silverlight has support for local storage. We are looking at creating Sl application that will work in off line mode. This application may require quite a bit of data to be cached on the client side. Obvious solution - use local storage with some sort of XMl based structure won't work as our PoC showed due to performance issues. We are looking at several 3rd party solutions that implement light database engines on top of SL local storage. If you have solved this problem in the past or have any ideas - I would appreciate some pointers and ideas.

• Norton Ghost EBAB03F1: The specified network name is no longer available.

  - by Breck Carter

  After about 15 minutes, a Norton Ghost 14 backup fails with Error EBAB03F1: The specified network name is no longer available. The source computer is a P4 laptop running Windows XP SP3. The target computer is a Core2 Quad desktop running Windows Vista Ultimate 64bit. It does not help to disable Norton 360 on the source computer or Norton Antivirus 2008 on the target computer. The Event Viewer consistently shows the same two VSS-related errors after Norton Ghost starts but before it fails. It makes no difference if the VSS service is started or stopped. The VSS errors do not appear elsewhere in the event log, only after Ghost starts. The MSS event messages, however, are quite common, appearing throughout the log, and they may have nothing to do with the problem. Here is the Norton Ghost error display... -Errors exist. --Unable to write to file. ---Error EBAB03F1: The specified network name is no longer available. ---Unable to set file size. ----Error EBAB03F1: The specified network name is no longer available. ----Unable to write to file. -----Error EBAB03F1: The specified network name is no longer available. -----Unable to set file size. ------Error EBAB03F1: The specified network name is no longer available.

• Delphi 2010 Professional and remote database access

  - by Kico Lobo

  Hi, When looking for which version of Delphi 2010 to buy, we found the following limitation on the professional one: Delphi 2010 Professional is designed for developers building high-performance desktop GUI and touch-screen applications with (or without) embedded and local database persistence. What does this really mean? Does this mean that we'll only face this restriction if we choose to use the native vcl components for database access we'll face this restriction. And what if we choose to use ADO components instead of those? In this case, how can Delphi avoid us to access remote database servers? Did anyone here ever tried this? Going even further: if we choose to use a database like Firebird, which is just one file, and used a network mapped drive. Could we be facing the same limitation? Supposing we opt for ADO, what will be the main consequences?

• c# Network Programming - HTTPWebRequest Scraping

  - by masterguru

  Hi, I am building a web scraping application. It should scrape a complex web site with concurrent HttpWebRequests from a single host to a single target web server. The application should run on Windows server 2008. One single HttpWebRequest for data could take from 1 minute to 4 minutes to complete (because of long running db operations) I should have at least 100 parallel requests to the target web server, but i have noticed that when i use more then 2-3 long-running requests i have big performance issues (request timeouts/hanging). How many concurrent requests can i have in this scenario from a single host to a single target web server? can i use Thread Pools in the application to run parallel HttpWebRequests to the server? will i have any issues with the default outbound HTTP connection/requests limits? what about Request timeouts when i reach outbound connection limits? what would be the best setup for my scenario? Any help would be appreciated. Thanks

• Collision Detection - Java - Rectangle

  - by Trizicus

  I would like to know if this is a good idea that conforms to best practices that does not lead to obscenely confusing code or major performance hit(s): Make my own Collision detection class that extends Rectangle class. Then when instantiating that object doing something such as Collision col = new Rectangle(); <- Should I do that or is that something that should be avoided? I am aware that I 'can' but should I? I want to extend Rectangle class because of the contains() and intersects() methods; should I be doing that or should I be doing something else for 2D collision detection in Java?

• Running each JUnit test in a separate JVM in Eclipse?

  - by HenryR

  I have a project with nearly 500 individual tests in around 200 test classes. Some of these tests don't do a great job of tearing down their own state after they're finished, and in Eclipse this results in some tests failing. The tests all pass when running the test suite from the command line via Ant. Can I enable 'test isolation' somehow in Eclipse? I don't mind if it takes longer to run. Long term, I will clean up the misbehaving tests, but in the short term I'd like to get the tests working.

• Linq: convert string to int array

  - by Oops

  I have a function (tointarray) to convert a string into an array of ints, but I am not very satisfied with it. it does the job but there must be a more elegant way to do this, perhaps Linq could help here. unfortunately I am not very good in Linq. do you guys know a better way? my function: { string s1 = "1;2;3;4;5;6;7;8;9;10;11;12"; int[] ia = tointarray(s1, ';'); } int[] tointarray(string value, char sep) { string[] sa = value.Split(sep); int[] ia = new int[sa.Length]; for (int i = 0; i < ia.Length; ++i) { int j; string s = sa[i]; if (int.TryParse(s, out j)) { ia[i] = j; } } return ia; }

• Do WPF ComboBox SelectedIndex and SelectedValue have different behavior on SelectionChanged event?

  - by Junior Mayhé

  Hello guys I got this cbxJobPosition_SelectionChanged firing as expected. The problem is when a external method tries to set cbxJobPosition. cbxJobPosition is databinded with a list of objects of type JobPosition: JobPositionID: 1, JobPositionName: Manager JobPositionID: 2, JobPositionName: Employee JobPositionID: 3, JobPositionName: Third party Here's the XAML: <ComboBox Cursor="Hand" DataContext="{Binding}" ItemsSource="{Binding}" FontSize="13" Name="cbxJobPosition" SelectedValuePath="JobPositionID" DisplayMemberPath="JobPositionName" SelectedIndex="0" Width="233" Height="23" SelectionChanged="cbxJobPosition_SelectionChanged" /> On UserControl_Loaded method, it reads from database the list of jobs and try to set the specific job position "Third party": //calls cbxJobPosition_SelectionChanged and passes the correct SelectedValue within cbxJobPosition.SelectedIndex = 3; //calls cbxJobPosition_SelectionChanged and but won't pass the correct SelectedValue within cbxJobPosition.SelectedValue = "3"; As you can notice, when the processing is automatically redirected to cbxJobPosition_SelectionChanged, the SelectedValue attribute will have different values for each statement above when you're debugging within cbxJobPosition_SelectionChanged event. Does anyone know if this difference is expected, am I missing something or it could be a bug?

• OutOfMemoryException - out of ideas II

  Hello, This question is related to my previous question. The storyline: I have an application which consumes a lot of memory if you look at task manager VMSize. I am trying to find out what consumes this amount of memory. You see in the picture below that VM size is 2,46 GB Ok now I am looking at .net performance counters Committed and reserved bytes add up to only 1,2 GB Now lets look at windb sos debugging. Let's run eeheap -gc command The heap size used by GC is only 340 MB. Where is the rest of used memory? I need to discover why WM size in TaskManager is 2.4 GB

• Why not port Linux kernel to Common Lisp?

  - by rplevy

  Conventional wisdom states that OS kernels must be written in C in order to achieve the necessary levels of performance. This has been the justification for not using more expressive high level languages. However, for a few years now implementations of Common Lisp such as SBCL have proven to be just as performant as C. What then are the arguments against redoing the kernel in a powerfully expressive language, namely Common Lisp? I don't think anyone (at least anyone who knows what they are talking about) could argue against the fact that the benefits in transparency and readability would be tremendous, not to mention all the things that can't be done in C that can be done in Lisp, but there may be implementation details that would make this a bad idea.

• SPWeb ProcessBatchData

  - by BeraCim

  Hi all: I'm currently using SPWeb's ProcessBatchData to update a lot of list items/folders into Sharepoint database. For example, in one batch update I have ~1200 objects to update. I also run it numerous times during different phases in my app. I found that it is generally faster and more efficient in updating large amount of items. But lately the performance of the app has decreased as more processes get added to the app (and also more batch updates). I was wondering whether the ProcessBatchData would be a suspect in slowing down the app? E.g. temporarily locking up db, draining resources, lagging network, etc. Thanks.

• issues horizontal scrolling using jQuery.ScrollTo / jQuery.SerialScroll

  - by kapil.israni

  Hi, I am trying to develop auto horizontal scrolling for our website using - jQuery.ScrollTo / jQuery.SerialScroll. I am not sure if this is the best jquery library to do that, but if there's something better, please let me know. Here's the behavior that I want, check out foursquare's "Recent Activity" list. The data that will refresh will come from a ajax request that I make every few seconds using window.setInterval. I am not really a CSS/java script guy so I havent been able to figure out jQuery.SerialScroll. Here's the website - look at the "Live job Feeds" list. Currently the list does refresh the data coming from the ajax call, but I dont see the effect, the animation, in fact I dont even think serialScroll is being used. Right now I am doing a - $('#feed-ticker').prepend(content) to pre-append the newly arrived data. You can do a view source to look at the current code. Any help would be really appreciated. Thanks.

• 10 lines of code per day is the global average!? -- true?

  - by Earlz

  Ok so last year I participated in a high school curriculum contest thing at a college(I currently attend this college). I actually got 1st in it but was still a bit angry I didn't get every single one right. The most baffling of questions on there was How many lines of code does the average programmer write per day? A. 5 B. 10 C. 25 D. 30 Aside from being a subjective question which depended on language and everything else I was more baffled at what they had as the correct answer. 10. Even on my bad days at my job I touch more than 10 lines of code(either adding, modifying, or deleting) per day. And when I took this test I had only programmed as a hobby where it was common for me to write a few hundred lines for one of my new projects per day. Where are they getting this random number of ten!? Is this published somewhere? A quick googling found me nothing.

  I'm using the new .NET 3.5 System.DirectoryServices.AccountManagement API. In my code, I need to determine the current System.DirectoryServices.AccountManagement.UserPrincipal. My naive approach was to do this: using AccountManagement = System.DirectoryServices.AccountManagement; ... // Determine current UserPrincipal. // (On my machine, this blocks for 5 seconds) // AccountManagement.UserPrincipal principal = AccountManagement.UserPrincipal.Current; My computer is a stand-alone machine running Vista. I am not part of any domain, etc. Any ideas on how to improve the performance?

• Client asked for internet radio on his website

  - by Ali

  Hi guys, I have a freelance job for a php site. The client isn't a tech savy guy he says he would like to have internet radio on his website as well. Now the thing is that when we speak of internet radio what are we actually talking about? My client himself has no idea of what internet radio is aside form listening to streaming mp3s on a flash player embedded on a website. I don't think my client would be ready to set up a radio station or so.. I have to give my client a report on what can and cannot be done. So I'm looking for the simplest solution possible that would pass off as internet radio...

• Too late to become a programmer?

  - by Tomas

  Hi, Working in IT for 5 years, I focused on system integration - testing, performance tests and analysis, automation etc. Altough I am working for one of the biggest IT companies, I have the possibility to come up with my own ideas and realize them - for example I have written C# (with SQL backend) bugtracker application with management elements...and I really liked it. I am very creative person but being 25 y/o, I am wondering whether it is too late. I understand the logic of programming but as I was never very good in math I assume I have no chance to become professional programmer in this age. What do you think? Thanks
