• Touch coordinates in iPhone landscape mode app

  - by gok

  I am trying to make this landscape only iphone app. I only use this code for this purpose: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationLandscapeRight); } However when I click clip subviews checkbox from interface builder, the view is clipped from the middle. I also don't receive any touch events from outside of view bounds obviously. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint fingerPos = [[touches anyObject] locationInView:self.view]; NSLog(@"%f %f",fingerPos.x,fingerPos.y); } only prints for coordinates between 20 and 320 for X. But Y works fine. When i try to modify bounds by hand, everything works fine; View is positioned and shown correctly, printed coordinates are correct, I receive touch from all of the screen except between 0 and 20 for X. So Left side of the screen is unresponsive to touch events for only 20 pixels. Code I use to modify bounds: self.view.bounds = CGRectMake(-180.0f, 0.0f, 680.0f, 480.0f); What might be causing this? Weird!

• Why `A & a = a` is valid?

  - by psaghelyi

  #include <iostream> #include <assert.h> using namespace std; struct Base { Base() : m_member1(1) {} Base(const Base & other) { assert(this != &other); // this should trigger m_member1 = other.m_member1; } int m_member1; }; struct Derived { Derived(Base & base) : m_base(m_base) {} // m_base(base) Base & m_base; }; void main() { Base base; Derived derived(base); cout << derived.m_base.m_member1 << endl; // crashes here } The above example is a synthesized version of a mistyped constructor. I used reference at the class member Derived::m_base because I wanted to make sure that the member will be initialized as the constructor had called. One problem is that nor GCC nor MSVC gives me a warning at m_base(m_base). But the more serious for me is that the assert finds everything fine and the application crashes later (sometimes far away from the mistake). Question: Is there any way to indicate such mistakes?

• Passing a LINQ DataRow Reference in a GridView's ItemTemplate

  - by Bob Kaufman

  Given the following GridView: <asp:GridView runat="server" ID="GridView1" AutoGenerateColumns="false" DataKeyNames="UniqueID" OnSelectedIndexChanging="GridView1_SelectedIndexChanging" > <Columns> <asp:BoundField HeaderText="Remarks" DataField="Remarks" /> <asp:TemplateField HeaderText="Listing"> <ItemTemplate> <%# ShowListingTitle( ( ( System.Data.DataRowView ) ( Container.DataItem ) ).Row ) %> </ItemTemplate> </asp:TemplateField> <asp:BoundField HeaderText="Amount" DataField="Amount" DataFormatString="{0:C}" /> </Columns> </asp:GridView> which refers to the following code-behind method: protected String ShowListingTitle( DataRow row ) { Listing listing = ( Listing ) row; return NicelyFormattedString( listing.field1, listing.field2, ... ); } The cast from DataRow to Listing is failing (cannot convert from DataRow to Listing) I'm certain the problem lies in what I'm passing from within the ItemTemplate, which is simply not the right reference to the current record from the LINQ to SQL data set that I've created, which looks like this: private void PopulateGrid() { using ( MyDataContext context = new MyDataContext() ) { IQueryable < Listing > listings = from l in context.Listings where l.AccountID == myAccountID select l; GridView1.DataSource = listings; GridView1.DataBind(); } }

• Testing a method that sends e-mail without sending the mail

  - by SnOrfus

  I have a method like public abstract class Base { public void MethodUnderTest(); } public class ClassUnderTest : Base { public override MethodUnderTest() { if(condition) { IMail mail = new Mail() { /* ... */ }; IMailer mailer = new Mailer() { /* ... */ } mailer.Send(mail); } else { /* ... */ } } } I have unit tests for this method, and the mail gets sent to myself, so it's not terrible (better than no test) but I'd prefer not to send the mail. The problem I have is that I don't want test specific code in the class (ie. if (testMode) return; instead of sending the mail) I don't know lots about DI, but I considered passing a mock IMailer into MethodUnderTest except that it overrides the base class, and no other class that derives from Base needs an IMailer object (I don't want to force implementers of Base to take an unnecessary IMailer in MethodUnderTest) What else can I do? (note: IMail and IMailer are part of an external library for sending e-mail. It's written in house, so I can modify it all I like if necessary, though I can't see a need to in this situation)

• UIScrollview calling superviews layoutSubviews when scrolling?

  - by marchinram

  Hello, I added a UITableView as a subview to a custom UIView class I'm working on. However I noticed that whenever I scroll the table it calls my classes layoutSubviews. I'm pretty sure its the UIScrollview that the table is inheriting from which is actually doing this but wanted to know if there is a way to disable this functionality and if not why is it happening? I don't understand why when you scroll a scrollview it needs its superview to layout its subviews. Code: @implementation CustomView - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { self.clipsToBounds = YES; UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 15.0, 436.0, 132.0) style:UITableViewStylePlain]; tableView.dataSource = self; tableView.delegate = self; tableView.separatorStyle = UITableViewCellSeparatorStyleNone; tableView.backgroundColor = [UIColor clearColor]; tableView.showsVerticalScrollIndicator = NO; tableView.contentInset = UIEdgeInsetsMake(kRowHeight, 0.0, kRowHeight, 0.0); tableView.tag = componentIndex; [self addSubview:tableView]; [tableView release]; } return self; } - (void)layoutSubviews { // This is called everytime I scroll the tableview } @end

• C# StreamReader.EndOfStream produces IOException

  - by Ziplin

  I'm working on an application that accepts TCP connections and reads in data until an </File> marker is read and then writes that data to the filesystem. I don't want to disconnect, I want to let the client sending the data to do that so they can send multiple files in one connection. I'm using the StreamReader.EndOfStream around my outter loop, but it throws an IOException when the client disconnects. Is there a better way to do this? private static void RecieveAsyncStream(IAsyncResult ar) { TcpListener listener = (TcpListener)ar.AsyncState; TcpClient client = listener.EndAcceptTcpClient(ar); // init the streams NetworkStream netStream = client.GetStream(); StreamReader streamReader = new StreamReader(netStream); StreamWriter streamWriter = new StreamWriter(netStream); while (!streamReader.EndOfStream) // throws IOException { string file= ""; while (file!= "</File>" && !streamReader.EndOfStream) { file += streamReader.ReadLine(); } // write file to filesystem } listener.BeginAcceptTcpClient(RecieveAsyncStream, listener); }

• Linq to SQL with INSTEAD OF Trigger and an Identity Column

  - by Bob Horn

  I need to use the clock on my SQL Server to write a time to one of my tables, so I thought I'd just use GETDATE(). The problem is that I'm getting an error because of my INSTEAD OF trigger. Is there a way to set one column to GETDATE() when another column is an identity column? This is the Linq-to-SQL: internal void LogProcessPoint(WorkflowCreated workflowCreated, int processCode) { ProcessLoggingRecord processLoggingRecord = new ProcessLoggingRecord() { ProcessCode = processCode, SubId = workflowCreated.SubId, EventTime = DateTime.Now // I don't care what this is. SQL Server will use GETDATE() instead. }; this.Database.Add<ProcessLoggingRecord>(processLoggingRecord); } This is the table. EventTime is what I want to have as GETDATE(). I don't want the column to be null. And here is the trigger: ALTER TRIGGER [Master].[ProcessLoggingEventTimeTrigger] ON [Master].[ProcessLogging] INSTEAD OF INSERT AS BEGIN SET NOCOUNT ON; SET IDENTITY_INSERT [Master].[ProcessLogging] ON; INSERT INTO ProcessLogging (ProcessLoggingId, ProcessCode, SubId, EventTime, LastModifiedUser) SELECT ProcessLoggingId, ProcessCode, SubId, GETDATE(), LastModifiedUser FROM inserted SET IDENTITY_INSERT [Master].[ProcessLogging] OFF; END Without getting into all of the variations I've tried, this last attempt produces this error: InvalidOperationException Member AutoSync failure. For members to be AutoSynced after insert, the type must either have an auto-generated identity, or a key that is not modified by the database after insert. I could remove EventTime from my entity, but I don't want to do that. If it was gone though, then it would be NULL during the INSERT and GETDATE() would be used. Is there a way that I can simply use GETDATE() on the EventTime column for INSERTs? Note: I do not want to use C#'s DateTime.Now for two reasons: 1. One of these inserts is generated by SQL Server itself (from another stored procedure) 2. Times can be different on different machines, and I'd like to know exactly how fast my processes are happening.

• How to keep only duplicates efficiently?

  - by Marc Eaddy

  Given an STL vector, I'd like an algorithm that outputs only the duplicates in sorted order, e.g., INPUT : { 4, 4, 1, 2, 3, 2, 3 } OUTPUT: { 2, 3, 4 } The algorithm is trivial, but the goal is to make it as efficient as std::unique(). My naive implementation modifies the container in-place: My naive implementation: void keep_duplicates(vector<int>* pv) { // Sort (in-place) so we can find duplicates in linear time sort(pv->begin(), pv->end()); vector<int>::iterator it_start = pv->begin(); while (it_start != pv->end()) { size_t nKeep = 0; // Find the next different element vector<int>::iterator it_stop = it_start + 1; while (it_stop != pv->end() && *it_start == *it_stop) { nKeep = 1; // This gets set redundantly ++it_stop; } // If the element is a duplicate, keep only the first one (nKeep=1). // Otherwise, the element is not duplicated so erase it (nKeep=0). it_start = pv->erase(it_start + nKeep, it_stop); } } If you can make this more efficient, elegant, or general, please let me know. For example, a custom sorting algorithm, or copy elements in the 2nd loop to eliminate the erase() call.

• Parse Text using scanner useDelimiter

  - by Brian

  Looking to parse the following text file: Sample text file: <2008-10-07text entered by user<2008-11-26additional text entered by user I would like to parse the above text so that I can have three variables: v1 = 2008-10-07 v2 = text entered by user v3 = Ted Parlor v1 = 2008-11-26 v2 = additional text entered by user v3 = Ted Parlor I attempted to use scanner and useDelimiter, however, I'm having issue on how to set this up to have the results as stated above. Here's my first attempt: enter code here import java.io.*; import java.util.Scanner; public class ScanNotes { public static void main(String[] args) throws IOException { Scanner s = null; try { //String regex = "(?<=\<)([^\*)(?=\)"; s = new Scanner(new BufferedReader(new FileReader("cur_notes.txt"))); s.useDelimiter("[<]+"); while (s.hasNext()) { String v1 = s.next(); String v2= s.next(); System.out.println("v1= " + v1 + " v2=" + v2); } } finally { if (s != null) { s.close(); } } } } The results is as follows: v1= 2008-10-07text entered by user v2=Ted Parlor What I desire is: v1= 2008-10-07 v2=text entered by user v3=Ted Parlor v1= 2008-11-26 v2=additional text entered by user v3=Ted Parlor Any help that would allow me to extract all three strings separately would be greatly appreciated.

• Delete NSManageObject at the event tableView:commitEditingStyle:forRowAtIndexPath:

  - by David.Chu.ca

  I got exception when I tried to delete one NSManageObject at the event of tableView:commitEditingStyle:forRowAtIndexPath:. Here is the part of my codes: - (void)tableView:(..)tableView commitEditingStyle:(..)editingStyle forRowAtIndexPath:(..)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [managedObjectContext deleteObject: [fetchedResultController objectAtIndexPath:indexPath]]; ... } } The exception was thrown at the line of deleteObject:(method of my local NSManagedObjectContext). This is the exception message: uncaught exception 'NSObjectInaccessibleException', reason: 'The NSManagedObject with ID:0x3d07a30 <x-coredata://0D2CC9CB-042B-496D-B3FE-5F1ED64EAB97/paymentType/p2> has been invalidated.' I tried to get entity object first and then to delete it. The entity looks OK but still the exception was at delete: NSManagedObject *entityToDelete = [fetchedResultsController objectAtIndexPath:indexPath]; [mangedObjectContext deleteObject:entityToDelete]; // Exception again. I am not sure if the entity object retrieved from the fetchedResultsController(NSFetchedResultsController type) cannot be deleted? If so, is there any other way to get the entity object for deleting? I found that in the Apple's Core Data Tutorial for iPhone with events example, there is on NSArray to hold event entity objects. I am not sure if that's necessory to use NSArray to hold my local entity objects and then use it for deleting?

• Custom Validation Attribute with Custom Model Binder in MVC 2

  - by griegs

  I apologise for the amount of code I have included. I've tried to keep it to a minimum. I'm trying to have a Custom Validator Attribute on my model as well as a Custom Model binder. The Attribute and the Binder work great seperately but if I have both, then the Validation Attribute no longer works. Here is my code snipped for readability. If I leave out the code in global.asax the custom validation fires but not if I have the custom binder enabled. Validation Attribute; public class IsPhoneNumberAttribute : ValidationAttribute { public override bool IsValid(object value) { //do some checking on 'value' here return true; } } Useage of the attribute in my model; [Required(ErrorMessage = "Please provide a contact number")] [IsPhoneNumberAttribute(ErrorMessage = "Not a valid phone number")] public string Phone { get; set; } Custom Model Binder; public class CustomContactUsBinder : DefaultModelBinder { protected override void OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) { ContactFormViewModel contactFormViewModel = bindingContext.Model as ContactFormViewModel; if (!String.IsNullOrEmpty(contactFormViewModel.Phone)) if (contactFormViewModel.Phone.Length > 10) bindingContext.ModelState.AddModelError("Phone", "Phone is too long."); } } Global asax; System.Web.Mvc.ModelBinders.Binders[typeof(ContactFormViewModel)] = new CustomContactUsBinder();

• Change NSTimer interval for repeating timer.

  - by user300713

  Hi, I am running a mainLoop in Cocoa using an NSTimer set up like this: mainLoopTimer = [NSTimer scheduledTimerWithTimeInterval:1.0/fps target:self selector:@selector(mainloop) userInfo:nil repeats:YES]; [[NSRunLoop currentRunLoop] addTimer:mainLoopTimer forMode:NSEventTrackingRunLoopMode]; At Program startup I set the timeInterval to 0.0 so that the mainloop runs as fast as possible. Anyways, I would like to provide a function to set the framerate(and thus the time interval of the timer) to a specific value at runtime. Unfortunately as far as I know that means that I have to reinitialize the timer since Cocoa does not provide a function like "setTimerInterval" This is what I tried: - (void)setFrameRate:(float)aFps { NSLog(@"setFrameRate"); [mainLoopTimer invalidate]; mainLoopTimer = nil; mainLoopTimer = [NSTimer scheduledTimerWithTimeInterval:1.0/aFps target:self selector:@selector(mainloop) userInfo:nil repeats:YES]; [[NSRunLoop currentRunLoop] addTimer:mainLoopTimer forMode:NSEventTrackingRunLoopMode]; } but this throws the following error and stops the mainloop: 2010-06-09 11:14:15.868 myTarget[7313:a0f] setFrameRate 2010-06-09 11:14:15.868 myTarget[7313:a0f] * __NSAutoreleaseNoPool(): Object 0x40cd80 of class __NSCFDate autoreleased with no pool in place - just leaking 2010-06-09 11:14:15.869 myTarget[7313:a0f] * __NSAutoreleaseNoPool(): Object 0x40e700 of class NSCFTimer autoreleased with no pool in place - just leaking 0.614628 I also tried to recreate the timer using the "retain" keyword, but that didn't change anything. Any ideas about how to dynamically change the interval of an NSTimer at runtime? Thanks!

• Learning AES: the KeyBytes

  I got the following example from here: import java.security.Security; import javax.crypto.Cipher; import javax.crypto.spec.SecretKeySpec; public class MainClass { public static void main(String[] args) throws Exception { Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); byte[] input = "www.java2s.com".getBytes(); byte[] keyBytes = new byte[] { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f, 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17 }; SecretKeySpec key = new SecretKeySpec(keyBytes, "AES"); Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding", "BC"); System.out.println(new String(input)); // encryption pass cipher.init(Cipher.ENCRYPT_MODE, key); byte[] cipherText = new byte[cipher.getOutputSize(input.length)]; int ctLength = cipher.update(input, 0, input.length, cipherText, 0); ctLength += cipher.doFinal(cipherText, ctLength); System.out.println(new String(cipherText)); System.out.println(ctLength); // decryption pass cipher.init(Cipher.DECRYPT_MODE, key); byte[] plainText = new byte[cipher.getOutputSize(ctLength)]; int ptLength = cipher.update(cipherText, 0, ctLength, plainText, 0); ptLength += cipher.doFinal(plainText, ptLength); System.out.println(new String(plainText)); System.out.println(ptLength); } } I imagine that the byte[] keyBytes should be random generated, so I gone to test the max size before do it. When adding one more byte 0x18 to the array, the exception raised: InvalidKeyException: Key length not 128/192/256 bits. But the original 18 bytes (from 0 to 17) are not multiple of nither 128, 192 or 256. I would like to understand the math here.. can anyone explain me? Thanks!

• iPhone app stopped building crash reports

  - by BankStrong

  My app formerly created useful crash logs. I synced my iPhone in the past and found crash logs in library/logs/CrashReporter About a month ago, my app stopped creating crash reports. When I first discovered this problem, I assumed it was due to memory corruption (a possibility in my app). I just created a new project and added a crash to it. // Implement viewDidLoad to do additional setup after loading the view, // typically from a nib. - (void)viewDidLoad { NSMutableArray *array = [[NSMutableArray alloc] init]; [array removeObjectAtIndex:-1]; [super viewDidLoad]; } This app does not create a crash report either. Ideas I've started to explore: My phone is corrupted (tried restoring - somehow I brought it to the state from a few months ago) My XCode is corrupt (tried reinstalling, but current download demands Snow Leopard - and I can't upgrade to Snow Leopard online). This seems possible - I may have messed with device support around a month ago (similar to http://stackoverflow.com/questions/1224867/does-iphone-os-3-0-1-ruin-your-development-phone ) The location for crash logs has somehow moved. Suggestions?

• Spring - SessionAttribute problem

  - by Max

  Hello, I want to implement something like this: @Controller @SessionAttributes("promotion") class PromotionController { @RequestMapping("showPromo") void showPromotionInfo( @RequestParam("promId") String promotionId, @ModelAttribute Promotion promotion, Errors errors ) { promotion = Promotions.get(promotionId); if (promotion == null || promotion.validates() == false) { errors.reject("promotion.invalid"); } return "prom"; } } The code is invalid, wont work and has some bad errors, but I don't know how to write it better. When user comes to an URL "showPromo?promId=15", controller should validate if the promotion is valid (outdated/non-existent/etc.). If it is valid - it should show it's information and save the promotion to model and session. If it's not - it should show some error about promotion being invalid. Problem is, I need to save the promotion in the session (for several requests) and don't want to use direct session management. Is it currently possible with Spring? Or am I doing something wrong? Could you please provide the optimal solution to my problem using Spring 3? Thanks in advance.

• RMI no such object in table, Server communication error

  - by ben-casey

  My goal is to create a Distributed computing program that launches a server and client at the same time. I need it to be able to install on a couple of machines and have all the machines communicating with each other, i.e. Master node and 5 slave nodes all from one application. My problem is that I cannot properly use unicastRef, I'm thinking that it is a problem with launching everything on the same port, is there a better way I am overlooking? this is part of my code (the part that matters) try { RMIServer obj = new RMIServer(); obj.start(5225); } catch (Exception e) { e.printStackTrace(); } try { System.out.println("We are slave's "); Registry rr = LocateRegistry.getRegistry("127.0.0.1", Store.PORT, new RClient()); Call ss = (Call) rr.lookup("FILLER"); System.out.println(ss.getHello()); } catch (Exception e) { e.printStackTrace(); } } this is my main class (above) this is the server class (below) public RMIServer() { } public void start(int port) throws Exception { try { Registry registry = LocateRegistry.createRegistry(port, new RClient(), new RServer()); Call stuff = new Call(); registry.bind("FILLER", stuff); System.out.println("Server ready"); } catch (Exception e) { System.err.println("Server exception: " + e.toString()); e.printStackTrace(); } } I don't know what I am missing or what I am overlooking but the output looks like this.

• BackgroundWorker.ReportProgress() not updating property and locking up the UI

  i am using a backgroundWorker to do a long running operation: BackgroundWorker backgroundWorker = new BackgroundWorker() { WorkerSupportsCancellation = true, WorkerReportsProgress = true }; backgroundWorker.RunWorkerCompleted += delegate(object s, RunWorkerCompletedEventArgs args) { }; backgroundWorker.ProgressChanged += delegate(object s, ProgressChangedEventArgs args) { someViewModel.SomeProperty.Add((SomeObject)args.UserState); }; backgroundWorker.DoWork += delegate(object s, DoWorkEventArgs args) { someViewModel.SomeList.ForEach(x => { someViewModel.SomeInterface.SomeMethod(backgroundWorker, someViewModel, someViewModel.SomeList, x); }); }; backgroundWorker.RunWorkerAsync(); Then in SomeInterface.SomeMethod: public void SomeMethod(BackgroundWorker backgroundWorker, SomeViewModel someViewModel//....) { //Filtering happens backgroundWorker.ReportProgress(0, someObjectFoundWhileFiltering); } So, when it comes to: backgroundWorker.ProgressChanged += delegate(object s, ProgressChangedEventArgs args) { someViewModel.SomeProperty.Add((SomeObject)args.UserState);//Adding the found object to the Property in the VM }; On the line someViewModel.SomeProperty.Add((SomeObject)args.UserState);, the set on the Property is not firering and the UI just locks up. What am i doing wrong? Is this the correct way to update the UI thread?

• iPhone UIView Animation Disables UIButton Subview

  - by bensnider

  So I've got a problem with buttons and animations. Basically, I'm animating a view using the UIView animations while also trying to listen for taps on the button inside the view. The view is just as large as the button, and the view is actually a subclass of UIImageView with an image below the button. The view is a subview of a container view placed in Interface Builder with user interaction enabled and clipping enabled. All the animation and button handling is done in this UIImageView subclass, while the startFloating message is sent from a separate class as needed. If I do no animation, the buttonTapped: message gets sent correctly, but during the animation it does not get sent. I've also tried implementing the touchesEnded method, and the same behavior occurs. UIImageView subclass init (I have the button filled with a color so I can see the frame gets set properly, which it does): - (id)initWithImage:(UIImage *)image { self = [super initWithImage:image]; if (self != nil) { // ...stuffs UIButton *tapBtn = [UIButton buttonWithType:UIButtonTypeCustom]; tapBtn.frame = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height); [tapBtn addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside]; tapBtn.backgroundColor = [UIColor cyanColor]; [self addSubview:tapBtn]; self.userInteractionEnabled = YES; } return self; } Animation method that starts the animation (if I don't call this the button works correctly): - (void)startFloating { [UIView beginAnimations:@"floating" context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:10.0f]; self.frame = CGRectMake(self.frame.origin.x, -self.frame.size.height, self.frame.size.width, self.frame.size.height); [UIView commitAnimations]; } So, to be clear: Using the UIView animation effectively disables the button. Disabling the animation causes the button to work. The button is correctly sized and positioned on screen, and moves along with the view correctly.

• using JMock to write unit test for a simple spring JDBC DAO

  - by Quincy

  I'm writing an unit test for spring jdbc dao. The method to test is: public long getALong() { return simpleJdbcTemplate.queryForObject("sql query here", new RowMapper<Long>() { public Long mapRow(ResultSet resultSet, int i) throws SQLException { return resultSet.getLong("a_long"); } }); } Here is what I have in the test: public void testGetALong() throws Exception { final Long result = 1000L; context.checking(new Expectations() {{ oneOf(simpleJdbcTemplate).queryForObject("sql_query", new RowMapper<Long>() { public Long mapRow(ResultSet resultSet, int i) throws SQLException { return resultSet.getLong("a_long"); } }); will(returnValue(result)); }}); Long seq = dao.getALong(); context.assertIsSatisfied(); assertEquals(seq, result); } Naturally, the test doesn't work (otherwise, I wouldn't be asking this question here). The problem is the rowmapper in the test is different from the rowmapper in the DAO. So the expectation is not met. I tried to put with around the sql query and with(any(RowMapper.class)) for the rowmapper. It wouldn't work either, complains about "not all parameters were given explicit matchers: either all parameters must be specified by matchers or all must be specified by values, you cannot mix matchers and values"

• Cast to delegate type fails in JScript.NET

  - by dnewcome

  I am trying to do async IO using BeginRead() in JScript.NET, but I can't get the callback function to work correctly. Here is the code: function readFileAsync() { var fs : FileStream = new FileStream( 'test.txt', FileMode.Open, FileAccess.Read ); var result : IAsyncResult = fs.BeginRead( new byte[8], 0, 8, readFileCallback ), fs ); Thread.Sleep( Timeout.Infinite ); } var readFileCallback = function( result : IAsyncResult ) : void { print( 'ListenerCallback():' ); } The exception is a cast failure: Unhandled Exception: System.InvalidCastException: Unable to cast object of type 'Microsoft.JScript.Closure' to type 'System.AsyncCallback'. at JScript 0.readFileAsync(Object this, VsaEngine vsa Engine) at JScript 0.Global Code() at JScript Main.Main(String[] ) I have tried doing an explicit cast both to AsyncCallback and to the base MulticastDelegate and Delegate types to no avail. Delegates are supposed to be created automatically, obviating the need for creating a new AsyncCallback explicitly, eg: BeginRead( ... new AsyncDelegate( readFileCallback), object ); And in fact if you try to create the delegate explicitly the compiler issues an error. I must be missing something here.

They are both accessing different media. this is on an ipad with a superview and two little views 320x240 right by eachother on the xib. -(IBAction)playLeft:(id)sender{ if ([self.playerRight playbackState] == MPMoviePlaybackStatePlaying); [self.playerRight stop]; [self.playerLeft play]; } -(IBAction)playRight:(id)sender{ if ([self.playerLeft playbackState] == MPMoviePlaybackStatePlaying); [self.playerLeft stop]; [self.playerRight play]; } - (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor viewFlipsideBackgroundColor]; self.playerLeft = [[MPMoviePlayerController alloc] init]; self.playerLeft.contentURL = [self movieURL]; NSLog(@"self.playerLeft %@", self.playerLeft); self.playerRight = [[MPMoviePlayerController alloc] init]; self.playerRight.contentURL = [self movieURL2]; NSLog(@"self.playerRight %@", self.playerRight); // START_HIGHLIGHT self.playerLeft.view.frame = self.leftView.bounds; self.playerLeft.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; self.playerRight.view.frame = self.rightView.bounds; self.playerRight.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [self.rightView addSubview:playerRight.view]; [self.leftView addSubview:playerLeft.view]; //[self.playerRight play]; //[self.playerLeft play]; //[self clickedOpenMovie:nil]; } -(NSURL *)movieURL { NSBundle *bundle = [NSBundle mainBundle]; NSString *moviePath = [bundle pathForResource:@"720p5994-prores-hq_iPhone_320x240 two" ofType:@"m4v"]; //NSString *moviePath = [NSString stringWithFormat:@"http://localhost:1935/live/aStream/playlist.m3u8"]; if (moviePath) { return [NSURL fileURLWithPath:moviePath]; //return [NSURL URLWithString:moviePath]; } else { return nil; } } -(NSURL *)movieURL2 { NSBundle *bundle = [NSBundle mainBundle]; NSString *moviePath = [bundle pathForResource:@"720p5994-prores-hq_iPhone_320x240" ofType:@"m4v"]; if (moviePath) { return [NSURL fileURLWithPath:moviePath]; } else { return nil; } }

• SharpPcap issue

  - by Eyla

  This is my first time to use SharpPcap library. I created new project with VC# 2008 and I added SharpPcap as a reference to my project. I post a sample code to get interface of my pc but I'm getting this error: Error 1 The type or namespace name 'PcapDeviceList' could not be found (are you missing a using directive or an assembly reference?) C:\Users\Ali\Documents\Visual Studio 2008\Projects\Pcap\Pcap\Form1.cs 28 13 Pcap please advice to solve this problem. here is my code: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using SharpPcap; using SharpPcap.Packets; using SharpPcap.Protocols; using SharpPcap.Util; namespace Pcap { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { /* Retrieve the device list */ PcapDeviceList devices = SharpPcap.GetAllDevices(); /*If no device exists, print error */ if (devices.Count < 1) { Console.WriteLine("No device found on this machine"); return; } int i = 0; /* Scan the list printing every entry */ foreach (PcapDevice dev in devices) { /* Description */ label1.Text = "{0}) {1}" + i + dev.PcapDescription +"\n"+ /* Name */ "\tName:\t{0}" + dev.PcapName+"\n"+ /* IP Address */ "\tIP Address: \t\t{0}"+ dev.PcapIpAddress+"\n"+ /* Is Loopback */ "\tLoopback: \t\t{0}"+ dev.PcapLoopback; i++; } } } }

• ASP.Net User Control Template Instantiation

  - by Chris

  Hi, I created a user control that has a template container. <cc:SearchResultItem ID="SearchResultItem1" Customer='<%# ((Customer)(((RepeaterItem)Container).DataItem)) %>' runat="server"> <NameTemplate> <%# Container.Name %> </NameTemplate> </cc:SearchResultItem> This is control is placed in a repeater which lists some customers. The customer is than bound to the user control. When the name template is instantiated in the container, the customer object is not yet available, but I need to access its name because it needs to get parsed before. protected void Page_Init(object sender, EventArgs e) { if (nameTemplate != null ) { // customer is null here, it is avaiable only after Page_Init... NameContainer container = new NameContainer(customer.Id, Parse(customer.Name)); nameTemplate.InstantiateIn(container); placeHolder.Controls.Add(container); } } Question: How can I access properties set for the user control BEFORE the template container is instantiated? Thanks in advance!
