• Is WPF a good choice for developing line of business user interfaces?

  - by Randy Minder

  We're debating whether our future Windows UI development should be WinForms or WPF. How have some of you made this decision? Most of our applications are LOB applications, and I'm not sure I see a clear and overwhelming benefit to WPF for these types of applications. However, my knowledge of WPF is limited. I'm also a little concerned that WPF will be in vogue for another couple years and then Microsoft will get tired of it and push something else on us. I guess one argument against this is the fact that Visual Studio 2010 is a WPF application. Thanks.

• What static analysis tools are available for C#?

  - by Paul Mrozowski

  What tools are there available for static analysis against C# code? I know about FxCop and StyleCop. Are there others? I've run across NStatic before but it's been in development for what seems like forever - it's looking pretty slick from what little I've seen of it, so it would be nice if it would ever see the light of day. Along these same lines (this is primarily my interest for static analysis), tools for testing code for multithreading issues (deadlocks, race conditions, etc.) also seem a bit scarce. Typemock Racer just popped up so I'll be looking at that. Anything beyond this? Real-life opinions about tools you've used are appreciated.

• Autoplay an Audio File on Mobile Safari

  - by phantomdata

  Hey guys, I've got a little system dashboard web app that I've written, replete with alarm notifications. I've had it working for quite some time on mobile safari, but recently wanted to add audio to the alarm notifications to allow me to easily know when there are alarms and I'm not looking directly at the display. The alarm notifications are populated through a (relatively) constantly polling ajax request that pulls in and displays an alarm banner if alarms are present. I wanted to add an auto-playing 'alarm' sound as well, but no dice for Safari Mobile. I've tried using HTML5 and embedded objects with no avail. The Apple documentation does state that you can't auto-play an audio file and it must be activated through user action to conserve bandwidth. Has anyone found a way around this in a WLAN setting?

• WCF client proxy initialization

  - by 123Developer

  I am consuming a WCF service and created its proxy using the VS 2008 service reference. I am looking for the best pattern to call WCF service method Should I create the client proxy instance every time I call the service method and close the client as soon as I am done with that? When I profiled my client application, I could see that it is taking lot of time to get the Channel while initializing the proxy client Should I use a Singleton pattern for the client proxy so that I can use the only once instance and get rid of the re-initializing overhead? Is there any hidden problem with this approach? I am using .Net framework 3.5 SP1, basicHttp binding with little customization.

• Regex for url formatting (www.domain.tld to anchors)

  - by Kristaps

  Hi. I'm currently developing a little browser-based Twitter widget. Currently, I'm stuck with getting the URLs to work. I'm kinda newbie, when it comes to regex (I know, how to get parts of a string, but this one – tough one). So, I need a regex that would search/replace www.domain.tld -> <a href="http://www.domain.tld">http://www.domain.tld</a> With/without http://, preferably. Any advice is welcome. Thanks.

• How do I set my development web browser in VS2010?

  - by blesh

  I don't like to use IE for my system default web browser. but I do want to set IE as my browser in VS2010 because it works a little nicer for debugging and I like to develop to the lowest common denominator. (jab, lol)... anyhow, can I default to debugging against IE? I know in VS2008 you just had to "Browse With..." on an .aspx page. But that option doesn't exist in VS2010 RC. What gives?

• Problems with dotLess Stopping characters and hacks list?

  - by rDeeb

  Have any one run into trouble when running dotLess and having hacks on your CSS files? Been working on a project... just installed dotLess after one year of development to ease a little bit the job of creating new CSS files for some new functionality of the web site, and recently our old CSS is not working correctly. Viewing the resulting CSS files we realized that the dotLess compiler stopeed at some hacks like this one: html>/**/body #itemTable .informationView fieldset textarea { min-height: 1.3em; height: 1.3em; } So we were wondering if there is any list of stopping words or hacks for dotLess?

• Can I detect if higher subview has been touched?

  - by Kevin Beimers

  I've got a big UIView that responds to touches, and it's covered with lots of little UIViews that respond differently to touches. Is it possible to touch anywhere on screen and slide around, and have each view know if it's being touched? For example, I put my finger down on the upper left and slide toward the lower right. The touchesBegan/Moved is collected by the baseView. As I pass over itemView1, itemView2, and itemView3, control passes to them. If I lift my finger while over itemView2, it performs itemView2's touchesEnded method. If I lift my finger over none of the items, it performs baseView's touchesEnded. At the moment, if I touch down on baseView, touchEnded is always baseView and the higher itemViews are ignored. Any ideas?

• What are the best uses for each programming language?

  - by VirtuosiMedia

  I come from a web developer background, so I'm fairly familiar with PHP and JavaScript, but I'd eventually like to branch out into other languages. At this point, I don't have a particular direction or platform that I'm leaning toward as far as learning a new language or what I would use it for, but I would like to learn a little bit more about programming languages in general and what each one is used for. I've often heard (and I agree) that you should use the right tool for the job, so what jobs are each programming language best suited for? Edit: If you've worked with some of the newer or more obscure languages, please share for those as well.

• GoTo statements, and alternatives (help me please im new) (VB.net)

  - by qais

  Basically I posted a code snippet on a forum asking for help and people pointed out to me that using GoTo statements is very bad programming practise so I'm just wondering, why is it bad? And also what alternative is there to use, like for example in this program ive done for homework the user has to input their date of birth and if the month/date/year are invalid or unrealistic(using if statements checking the integer inputs size, if theres any better way to do this i'd appreciate if you could tell me that also :D) then how would i be able to loop back to ask them again? heres a little extract of my code retryday: Console.WriteLine("Please enter the day you were born : ") day = Console.ReadLine If day > 31 Or day < 1 Then Console.WriteLine("Please enter a valid day") GoTo retryday End If

• WCF Project vs. A folder in the existing website project?

  - by user193189

  What way makes the most sense? I have a ASP.NET app... and maybe a Silverlight app in the future.. I want both to talk to web services.. At first, I like have the WCF project be by it self for the seperation.. But then I thought.. What is the point since I can just as easily have a 'WEBSERVICES' folder that contains all the .svc files and code in the EXISTING website project. ... Atleast that way.. deploying to a remote host will be a little easier since everything is in one project.. any other considerations ?

• GUI Framework for flash (as3)

  - by widgisoft

  I can't seem to find any GUI framework's for as3 that are as good as any the applications I already see out on the web; Is this something most people code themselves or am I missing something in flash itself? I'm looking for dialogs/windows, buttons, text boxes, combos, drop downs, menus, etc etc and the ability to extend the components to make new ones. I'd also prefer it to be as3 but any others will do also. May need to elaborate a little.. I'm actually looking for a framework to allow me to create my own GUIs in flash, custom skins, colors, styles, etc.

• How do I create a Launcher in Ubuntu 9.1 that runs a shell script?

  - by mkelley33

  Here's my situation: New to Ubuntu (just nstalled 9.10 Karmic Koala 64 bit) Purpose: to easily run PyCharm without too much typing (ie. cd... ./pycharm.sh) Want to create desktop Launcher instead of terminal & typing (without resorting to the "Run in Terminal" option) Tried to create Launcher to executes .sh script in Document directory Right-clicked Desktop Create Launcher a. Type == Application; Browse [insert absolute path to .sh script]; no luck b. Type == Application in Terminal; Browse ...ditto I'm open to any other alternatives that involve as little typing as possible. I would like to just start Ubuntu, click Launcher icons, and have terminals spring to life, running the intended scripts. Crazy? No. Lazy? Probably. Productive? Hopefully :)

• VB to C# conversion incongruency with lambdas

  - by Jason

  I have a bit of code that I have been tasked with converting to C# from VB. A snippet of mine seems like it cannot be converted from one to the other, and if so, I just don't know how to do it and am getting a little frustrated. Here's some background: OrderForm is an abstract class, inherited by Invoice (and also PurchaseOrder). The following VB snippet works correctly: Dim Invs As List(Of OrderForm) = GetForms(theOrder.OrderID) .... Dim inv As Invoice = Invs.Find( Function(someInv As Invoice) thePO.SubPONumber = someInv.SubInvoiceNumber) In C#, the best I came to converting this is: List<OrderForm> Invs = GetForms(theOrder.OrderID); .... Invoice inv = Invs.Find( (Invoice someInv) => thePO.SubPONumber == someInv.SubInvoiceNumber); However, I get the following error when I do this: Cannot convert lambda expression to delegate type 'System.Predicate' because the parameter types do not match the delegate parameter types Is there any way to fix this without restructuring my whole codebase?

• Calling a COM+ Component remotely using C#

  - by Arturo Caballero

  Hello, I have a little COM+ component as a service on a remote server. I´m trying to execute a method of this component using: Type type = Type.GetTypeFromProgID("ComPlusTest.ComTestClass",serverName); // Create Service Object service = Activator.CreateInstance(type); // Execute Method String result = service.GetType().InvokeMember("LaunchPackage", BindingFlags.InvokeMethod, null, parameters, null).ToString(); The type is returned as null. What is the best way to do this?? The server is Windows 2003 Enterprise, the service is a .NET component wraped as COM+ (I know that I don´t have to do it that way, but the purpose is to itegrate a legacy App with a .NET component) The purpose of this is just to test that the .NET COM+ Component works. Thanks in advance!

• How to activate nVidia cards programmatically on new MacBookPros for CUDA programming?

  - by Carsten Kuckuk

  The new MacBookPros come with two graphic adapters, the Intel HD Graphics, and the NVIDIA GeForce GT 330M. OS X switches back and forth between them, depending on the workload, detection of an external monitor, or activation of Rosetta. I want to get my feet wet with CUDA programming, and unfortunately the CUDA SDK doesn't seem to take care of this back-and-forth switching. When Intel is active, no CUDA device gets detected, and when the NVidia card is active, it gets detected. So my current work-around is to use the little tool gfxCardStatus (http://codykrieger.com/gfxCardStatus/) to force the card on or off, just as I need it, but that's not satisfactory. Does anybody here know what the Apple-blessed, Apple-recommended way is to (1) detect the presence of a CUDA card, (2) to activate this card when present?

• How do I put my return data from an asmx into JSON? I'm having trouble finding decent literature

  - by jphenow

  I want to return an array of javascript objects from my asp.net asmx file. ie. variable = [ { *value1*: 'value1', *value2*: 'value2', ..., }, { . . } ]; I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable. Thanks in advance for assistance.

• Efficient way to create/unpack large bitfields in C?

  - by drhorrible

  I have one microcontroller sampling from a lot of ADC's, and sending the measurements over a radio at a very low bitrate, and bandwidth is becoming an issue. Right now, each ADC only give us 10 bits of data, and its being stored in a 16-bit integer. Is there an easy way to pack them in a deterministic way so that the first measurement is at bit 0, second at bit 10, third at bit 20, etc? To make matters worse, the microcontroller is little endian, and I have no control over the endianness of the computer on the other side.

• Which distribution website should I pick for my open-source package?

  - by Frank

  I wrote an open-source software package, which I'd like to publish (using Apache 2 license). I see various options for how/where to publish/host it: Get my own domain and put it there Put it on Sourceforge Put it on Google Code Put it on Freshmeat ...? What are your experiences / recommendations? What's the current trend among software developers? My only requirements are that I ... can add my own logo on the website can put up some documentation there, get a nice URL that is easy to remember get SVN support (I would also be fine with just uploading a tarball for each new version, it just shouldn't force me to use CVS or any other version control system I'm not familiar with) and of course, the site shouldn't take ownership in the code etc. oh, and it should be free (ok, for registering my own domain I'll be willing to pay a little bit)

• can I read exactly one UDP packet off a socket?

  - by Brian Palmer

  Using UNIX socket APIs on Linux, is there any way to guarantee that I read one UDP packet, and only one UDP packet? I'm currently reading packets off a non-blocking socket using recvmsg, with a buffer size a little larger than the MTU of our internal network. This should ensure that I can always receive the full UDP packet, but I'm not sure I can guarantee that I'll never receive more than one packet per recvmsg call, if the packets are small. The recvmsg man pages reference the MSG_WAITALL option, which attempts to wait until the buffer is filled. We're not using this, so does that imply that recvmsg will always return after one datagram is read? Is there any way to guarantee this? Ideally I'd like a cross-UNIX solution, but if that doesn't exist is there something Linux specific?

• Multi-Threading in .NET

  - by AIC

  Hi all.. I wrote this program, that is supposed to read about 5000 email address and send an pre-defined html mail. I am using the background worker component. The problem is this: I have wired up the method who is supposed to send the mail. But I am calling another method that is supposed to append the body html to the salutation, like public string GiveMeFullHtml(string personname) ... "Dear Mr. John Doe" + HTML ... It seems that when it hits this method call, operation completes. IUt only sends the first mail and completes. I think because the HTML string method is on another thread or sth like that. Can you give me a little insight. Do I have to get everything done in the very same method when using multi-threading? Thanks in advance
