  • Why have or haven't you moved to ASP.NET MVC yet?

    - by Jason
    I find myself on the edge of trying out ASP.NET MVC but there is still "something" holding me back. Are you still waiting to try it, and if so, why? If you finally decided to use it, what helped you get over your hesitation? I'm not worried about it from a technical point of view; I know the pros and cons of web forms vs MVC. My concerns are more on the practical side. Will Microsoft continue to support ASP.NET MVC if they don't reach some critical threshold of developers/customers using it? Are customers willing to try ASP.NET MVC? Have you had to convince a customer to use it? How did that go? Are there major sites using ASP.NET MVC (besides SO)? Could you provide links if you have them? Did you try ASP.NET MVC and found yourself regretting it? If so, what do you regret? If you have any other concerns preventing you from using MVC.NET, what are they? If you had concerns but felt they were addressed and now use MVC.NET, could you list them as well? Thanks

  • How to test the XML sent to a web service in Ruby/Rails

    - by Jason Langenauer
    I'm looking for the best way to write unit test for code that POSTs to an external web service. The body of the POST request is an XML document which describes the actions and data for the web service to perform. Now, I've wrapped the webservice in its own class (similar to ActiveResource), and I can't see any way to test the exact XML being generated by the class without breaking encapsulation by exposing some of the internal XML generation as public methods on the class. This seems to be a code smell - from the point-of-view of the users of the class, they should not know, nor care, how the class actually implements the web service call, be it with XML, JSON or carrier pigeons. For an example of the class: class Resource def new #initialize the class end def save! Http.post("http://webservice.com", self.to_xml) end private def to_xml # returns an XML representation of self end end I want to be able to test the XML generated to ensure it conforms to what the specs for the web service are expecting. So can I best do this, without making to_xml a public method?

  • Animated gifs in QMovie

    - by Jason
    I'm displaying an animated gif in my application by creating a QLabel, and setting the movie as a QMovie. The problem I'm having is that when the gif is displayed, any part of the image that stays a constant color throughout the animation shows up as the background color. I hope I'm explaining that clearly. Here's the code I'm using to create the animation if that helps: rewardLabel=new QLabel(); rewardLabel->setCursor(QCursor(Qt::BlankCursor)); rewardLabel->setWindowFlags(Qt::FramelessWindowHint); rewardLabel->hide(); string movieTemp="animations/"+animationFiles[animationIndex]; QString movieFile(movieTemp.c_str()); rewardMovie=new QMovie(movieFile); rewardLabel->setMovie(rewardMovie); Let me know if I need to explain the situation better. Thanks in advance.

  • IPP linker errors on cygwin

    - by Jason Sundram
    I've built a program that uses mkl and ipp that runs on mac and linux. I'm now building that program for Windows using cygwin and gcc, and can't get it to link. The errors I'm getting are: Warning: .drectve -defaultlib:"uuid.lib" ' unrecognized ../../../bin/libMath.a(VectorUtility.cxx.o):VectorUtility.cxx:(.text+0x95): undefined reference to _ippGetLibVersion' ../../../bin/libMath.a(VectorUtility.cxx.o):VectorUtility.cxx:(.text+0x157): undefined reference to `_ippsWinHann_32f_I' (and many more like that). I'm using link path: /opt/intel/IPP/6.1.2.041/ia32/lib and linking to the following: ippiemerged, ippimerged, ippmemerged, ippmmerged, ippsemerged, ippsmerged and ippcorel. Can someone point me to what I'm doing wrong?

  • Why isn't the Cache invalidated after table update using the SqlCacheDependency?

    - by Jason
    I have been trying to get SqlCacheDependency working. I think I have everything set up correctly, but when I update the table, the item in the Cache isn't invalidated. Can you look at my code and see if I am missing anything? I enabled the Service Broker for the Sandbox database. I have placed the following code in the Global.asax file. I also restart IIS to make sure it is called. void Application_Start(object sender, EventArgs e) { SqlDependency.Start(ConfigurationManager.ConnectionStrings["SandboxConnectionString"].ConnectionString); } I have placed this entry in the web.config file: <system.web> <caching> <sqlCacheDependency enabled="true" pollTime="10000"> <databases> <add name="Sandbox" connectionStringName="SandboxConnectionString"/> </databases> </sqlCacheDependency> </caching> </system.web> I call this code to put the item into the cache: protected void CacheDataSetButton_Click(object sender, EventArgs e) { using (SqlConnection sqlConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["SandboxConnectionString"].ConnectionString)) { using (SqlCommand sqlCommand = new SqlCommand("SELECT PetID, Name, Breed, Age, Sex, Fixed, Microchipped FROM dbo.Pets", sqlConnection)) { using (SqlDataAdapter sqlDataAdapter = new SqlDataAdapter(sqlCommand)) { DataSet petsDataSet = new DataSet(); sqlDataAdapter.Fill(petsDataSet, "Pets"); SqlCacheDependency petsSqlCacheDependency = new SqlCacheDependency(sqlCommand); Cache.Insert("Pets", petsDataSet, petsSqlCacheDependency, DateTime.Now.AddSeconds(10), Cache.NoSlidingExpiration); } } } } Then I bind the GridView with this code: protected void BindGridViewButton_Click(object sender, EventArgs e) { if (Cache["Pets"] != null) { GridView1.DataSource = Cache["Pets"] as DataSet; GridView1.DataBind(); } } Between attempts to DataBind the GridView, I change the table's values expecting it to invalidate the Cache["Pets"] item, but it seems to stay in the Cache indefinitely.

  • UIDatePicker inside UIScrollView with pages

    - by Jason Martens
    I have a UIScrollView with 2 pages, and I can scroll horizontally between them. However, on one of my pages, I have a UIDatePicker, and the scroll view is intercepting the vertical touch events so I can no longer manipulate the date picker (except by clicking or tapping). Is there some way to tell the ScrollView to send the vertical touch events to the date picker, but send the horizontal touch events to the scroll view to switch pages?

  • How to prevent "This program might not have installed correctly" messages on Vista

    - by Jason
    I have a product setup executable that copies some files to the user's hard drive. It's not a typical installer in the normal sense (it doesn't add anything to the Start Menu or Program Files folders). Each time the setup program is run on Vista, after the exe terminates, Vista produces a task dialog: This program might not have installed correctly Reinstall using recommended settings This program installed correctly Is there a function I need to call from the exe or registry entry to set, to indicate to the operating system that the program installed correctly (or to at least supress this message)? Related questions: http://stackoverflow.com/questions/1069135/this-program-might-not-have-installed-correctly-message-in-windows-7-rc (for Windows 7-specific issues)

  • 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?

  • CSS: Why won't this box get wider?

    - by Jason
    I just need a sanity check here... DEMO Basically, I can't figure out how to get the box under the link to get wider as more content is added. It seems fixed to the width of the parent div (or the width of, say, the longest element like the select or a really long word with no spaces), despite being absolutely positioned. I use this trick all the time with ul and li but it doesn't make sense to use that in my situation, and for some crazy reason it just won't work with a div inside a div. I don't want to set a width (which, of course, works) because I don't always know what will be in this box. GRR Thanks :\

  • Can't upload images with Magento 1.4 on Windows/IIS

    - by Jason
    Everything else works in Magento 1.4 but I can't upload images. Running on Windows/IIS. I know it isn't officially supported but seems odd that everything works but something as simple as image uploads. Tried updating the media path and that is correct. Also updated permissions on directories, but nothing has worked. Any other ideas to get this to work? thanks

  • array of structures, or structure of arrays?

    - by Jason S
    Hmmm. I have a table which is an array of structures I need to store in Java. The naive don't-worry-about-memory approach says do this: public class Record { final private int field1; final private int field2; final private long field3; /* constructor & accessors here */ } List<Record> records = new ArrayList<Record>(); If I end up using a large number ( 106 ) of records, where individual records are accessed occasionally, one at a time, how would I figure out how the preceding approach (an ArrayList) would compare with an optimized approach for storage costs: public class OptimizedRecordStore { final private int[] field1; final private int[] field2; final private long[] field3; Record getRecord(int i) { return new Record(field1[i],field2[i],field3[i]); } /* constructor and other accessors & methods */ } edit: assume the # of records is something that is changed infrequently or never I'm probably not going to use the OptimizedRecordStore approach, but I want to understand the storage cost issue so I can make that decision with confidence. obviously if I add/change the # of records in the OptimizedRecordStore approach above, I either have to replace the whole object with a new one, or remove the "final" keyword. kd304 brings up a good point that was in the back of my mind. In other situations similar to this, I need column access on the records, e.g. if field1 and field2 are "time" and "position", and it's important for me to get those values as an array for use with MATLAB, so I can graph/analyze them efficiently.

  • Flash SWF not initializing until visible - can I force them to initialize?

    - by Jason
    I have an application that needs to render about 100 flash graphs (as well as other DOM stuff) in a series of rows that vertically extend many times beyond the current visible window - in other words, the users have to scroll down see see all the different graphs. This application is also dynamic and when a user changes a value in the DOM (anywhere on the page) it will need to propagate that change to all the Flash graphs at the same time. So I setup all the externalInterface callbacks and was careful to not let any JS start going until the ever-so-important "flashIsReady" call and...it worked great until I tried to update() the existing swf's with new data. Here was the behavior: - All the swfs load (initially) in both IE/Fox = good. - Updating swfs with new content works in IE but not in Fox = not good - Updating swfs with new content works in Fox --ONLY IF-- I scrolled down to the bottom of the page, then back to the top -- BEFORE -- I triggered an update(). So then I started tracing out each time a swf called the JS to say "flash is ready" and I realized, Firfox only renders swfs as they become visible. And To be honest - that's fine and actually, I am pretty sure that IE does this too. But the problem is that not only does Firefox not initialize the swf, Firefox doesn't even acknowledge the swf exists (expect for after onload) if it has not yet been visible. And the proof is that you get JS errors saying: "[FlashDOMID].FlashMethod is not a function". However, scroll down a little, wait until its visible and suddenly the trace starts lighting up "Flash Ready", "Flash Ready", "Flash Ready" and once they are all ready, everything works fine. Someone told me that FF does not init swf's until visible - can I force it? I can post code if you need...but its pretty heavy (hard to strip out the relevant from the rest) and I would like to avoid it (for your sakes) if possible. The question is simple - have you had this happen and if so, did you find a solution? Does anyone now how to force a not-yet-visible swf to initialize? Thanks guys.

  • Is this __import__ functionality correct?

    - by Jason Baker
    I have a package named jiva_tasks, which I'm trying to import via celery (using the CELERY_IMPORTS attribute of celeryconfig. The import statement that celery is using is this: __import__(module, [], [], ['']) Oddly enough, when this syntax is used, the module gets imported twice, once as jiva_tasks and another time as jiva_tasks. (with a period at the end). Now, chances are good that celery should be passing in globals rather than an empty list, but this seems broken to me. It seems odd that even if given the wrong arguments, __import__ would import something that isn't a valid python module name. I know that the way to fix this is to pass in globals, but I want to understand why I'm getting this result. Is this a bug, or is there something I don't understand about how __import__ is working? Update: It also seems to be working fine if I use importlib.

  • ASP.net Usercontrol caching viewstate across users?

    - by Jason
    I have a usercontrol with asp:textbox controls on it that also performs postbacks. If two users, who are both identified by a different session variable, postback the page within the same second, one user will see the other user's viewstate values in the text boxes. I have validated that this happens by setting a textbox, a session variable, and a cookie to the same value (the same value that identifies the user) and writing to the log when all three don't match. The text box's value is the one that is logged as the other user's value. ASP.net 3.5, IIS 6 Has anyone experienced this issue.

  • JavaScript / HTML highlighting / debugging in Eclipse using PhoneGap

    - by Jason Hartley
    I am writing an app using PhoneGap for Android in Eclipse. Since the project is an Android project, it's in a Java perspective. For whatever reason, Eclipse won't highlight HTML and JavaScript for me while in an Android/Java project/perspective and switching to the JavaScript perspective doesn't highlight the code either. Without highlighting or debugging tools, the debug process is very slow. How do I tell Eclipse to highlight HTML and JavaScript for me while working in a Java Environment?

  • CoreData: Same predicate (IN) returns different fetched results after a Save operation

    - by Jason Lee
    I have code below: NSArray *existedTasks = [[TaskBizDB sharedInstance] fetchTasksWatchedByMeOfProject:projectId]; [context save:&error]; existedTasks = [[TaskBizDB sharedInstance] fetchTasksWatchedByMeOfProject:projectId]; NSArray *allTasks = [[TaskBizDB sharedInstance] fetchTasksOfProject:projectId]; First line returns two objects; Second line save the context; Third line returns just one object, which is contained in the 'two objects' above; And the last line returns 6 objects, containing the 'two objects' returned at the first line. The fetch interface works like below: WXModel *model = [WXModel modelWithEntity:NSStringFromClass([WQPKTeamTask class])]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(%@ IN personWatchers) AND (projectId == %d)", currentLoginUser, projectId]; [model setPredicate:predicate]; NSArray *fetchedTasks = [model fetch]; if (fetchedTasks.count == 0) return nil; return fetchedTasks; What confused me is that, with the same fetch request, why return different results just after a save? Here comes more detail: The 'two objects' returned at the first line are: <WQPKTeamTask: 0x1b92fcc0> (entity: WQPKTeamTask; id: 0x1b9300f0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p9> ; data: { projectId = 372004; taskId = 338001; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); } <WQPKTeamTask: 0xf3f6130> (entity: WQPKTeamTask; id: 0xf3cb8d0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p11> ; data: { projectId = 372004; taskId = 340006; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); } And the only one object returned at third line is: <WQPKTeamTask: 0x1b92fcc0> (entity: WQPKTeamTask; id: 0x1b9300f0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p9> ; data: { projectId = 372004; taskId = 338001; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); } Printing description of allTasks: <_PFArray 0xf30b9a0>( <WQPKTeamTask: 0xf3ab9d0> (entity: WQPKTeamTask; id: 0xf3cda40 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p6> ; data: <fault>), <WQPKTeamTask: 0xf315720> (entity: WQPKTeamTask; id: 0xf3c23a0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p7> ; data: <fault>), <WQPKTeamTask: 0xf3a1ed0> (entity: WQPKTeamTask; id: 0xf3cda30 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p8> ; data: <fault>), <WQPKTeamTask: 0x1b92fcc0> (entity: WQPKTeamTask; id: 0x1b9300f0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p9> ; data: { projectId = 372004; taskId = 338001; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); }), <WQPKTeamTask: 0xf325e50> (entity: WQPKTeamTask; id: 0xf343820 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p10> ; data: <fault>), <WQPKTeamTask: 0xf3f6130> (entity: WQPKTeamTask; id: 0xf3cb8d0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p11> ; data: { projectId = 372004; taskId = 340006; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); }) ) UPDATE 1 If I call the same interface fetchTasksWatchedByMeOfProject: in: #pragma mark - NSFetchedResultsController Delegate - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { I will get 'two objects' as well. UPDATE 2 I've tried: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(ANY personWatchers == %@) AND (projectId == %d)", currentLoginUser, projectId]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(ANY personWatchers.personId == %@) AND (projectId == %d)", currentLoginUserId, projectId]; Still the same result. UPDATE 3 I've checked the save:&error, error is nil.

  • Handling Exceptions that happen in a asp.net MVC Controller Constructor

    - by Jason
    What's the best way to handle exceptions that happen from within a controller's constructor? All I can think of to do is use Application_OnError() or put a try/catch in my ControllerFactory. Neither of these solutions seem ideal. Application_OnError is to broad - I have some non-mvc content in the site that has its own error handling. Using a try/catch block seems kinda hacky. If I'm serving different content type -html/text/json/rss.... I would like to be able to handle the exception from within the action method instead of having to write all kinds of conditions to determine what kind of error message to serve. Am I missing something here, or has anyone else dealt with this?
