• Exclude string from wildcard in bash

  - by Peter O'Doherty

  Hi, I'm trying to adapt a bash script from "Sams' Teach Yourself Linux in 24 Hours" which is a safe delete command called rmv. The files are removed by calling rmv -d file1 file2 etc. In the original script a max of 4 files can by removed using the variables $1 $2 $3 $4. I want to extend this to an unlimited number of files by using a wildcard. So I do: for i in $* do mv $i $HOME/.trash done The files are deleted okay but the option -d of the command rmv -d is also treated as an argument and bash objects that it cannot be found. Is there a better way to do this? Thanks, Peter #!/bin/bash # rmv - a safe delete program # uses a trash directory under your home directory mkdir $HOME/.trash 2>/dev/null # four internal script variables are defined cmdlnopts=false delete=false empty=false list=false # uses getopts command to look at command line for any options while getopts "dehl" cmdlnopts; do case "$cmdlnopts" in d ) /bin/echo "deleting: \c" $2 $3 $4 $5 ; delete=true ;; e ) /bin/echo "emptying the trash..." ; empty=true ;; h ) /bin/echo "safe file delete v1.0" /bin/echo "rmv -d[elete] -e[mpty] -h[elp] -l[ist] file1-4" ;; l ) /bin/echo "your .trash directory contains:" ; list=true ;; esac done if [ $delete = true ] then for i in $* do mv $i $HOME/.trash done /bin/echo "rmv finished." fi if [ $empty = true ] then /bin/echo "empty the trash? \c" read answer case "$answer" in y) rm -i $HOME/.trash/* ;; n) /bin/echo "trashcan delete aborted." ;; esac fi if [ $list = true ] then ls -l $HOME/.trash fi

• Validation without ServiceLocator

  - by Dmitriy Nagirnyak

  Hi, I am getting back again and again to it thinking about the best way to perform validation on POCO objects that need access to some context (ISession in NH, IRepository for example). The only option I still can see is to use S*ervice Locator*, so my validation would look like: public User : ICanValidate { public User() {} // We need this constructor (so no context known) public virtual string Username { get; set; } public IEnumerable<ValidationError> Validate() { if (ServiceLocator.GetService<IUserRepository>().FindUserByUsername(Username) != null) yield return new ValidationError("Username", "User already exists.") } } I already use Inversion Of control and Dependency Injection and really don't like the ServiceLocator due to number of facts: Harder to maintain implicit dependencies. Harder to test the code. Potential threading issues. Explicit dependency only on the ServiceLocator. The code becomes harder to understand. Need to register the ServiceLocator interfaces during the testing. But on the other side, with plain POCO objects, I do not see any other way of performing the validation like above without ServiceLocator and only using IoC/DI. So the question would be: is there any way to use DI/IoC for the situation described above? Thanks, Dmitriy.

• Soft Paint Bucket Fill: Colour Equality

  - by Bart van Heukelom

  I'm making a small app where children can fill preset illustrations with colours. I've succesfully implemented an MS-paint style paint bucket using the flood fill argorithm. However, near the edges of image elements pixels are left unfilled, because the lines are anti-aliased. This is because the current condition on whether to fill is colourAtCurrentPixel == colourToReplace (the colours are RGB uints) I'd like to add a smoothing/treshold option like in Photoshop and other sophisticated tools, but what's the algorithm to determine the equality/distance between two colours? if (match(pixel(x,y), colourToReplace) setpixel(x,y,colourToReplaceWith) How to fill in match()? Here's my current full code: var b:BitmapData = settings.background; b.lock(); var from:uint = b.getPixel(x,y); var q:Array = []; var xx:int; var yy:int; var w:int = b.width; var h:int = b.height; q.push(y*w + x); while (q.length != 0) { var xy:int = q.shift(); xx = xy % w; yy = (xy - xx) / w; if (b.getPixel(xx,yy) == from) { b.setPixel(xx,yy,to); if (xx != 0) q.push(xy-1); if (xx != w-1) q.push(xy+1); if (yy != 0) q.push(xy-w); if (yy != h-1) q.push(xy+w); } } b.unlock(null);

• Parameterized Queries /Without/ using queries.

  - by Aren B

  I've got a bit of a poor situation here. I'm stuck working with commerce server, which doesn't do a whole lot of sanitization/parameterization. I'm trying to build up my queries to prevent SQL Injection, however some things like the searches / where clause on the search object need to be built up, and there's no parameterized interface. Basically, I cannot parameterize, however I was hoping to be able to use the same engine to BUILD my query text if possible. Is there a way to do this, aside from writing my own parameterizing engine which will probably still not be as good as parameterized queries? Update: Example The where clause has to be built up as a sql query where clause essentially: CatalogSearch search = /// Create Search object from commerce server search.WhereClause = string.Format("[cy_list_price] > {0} AND [Hide] is not NULL AND [DateOfIntroduction] BETWEEN '{1}' AND '{2}'", 12.99m, DateTime.Now.AddDays(-2), DateTime.Now); *Above Example is how you refine the search, however we've done some testing, this string is NOT SANITIZED. This is where my problem lies, because any of those inputs in the .Format could be user input, and while i can clean up my input from text-boxes easily, I'm going to miss edge cases, it's just the nature of things. I do not have the option here to use a parameterized query because Commerce Server has some insane backwards logic in how it handles the extensible set of fields (schema) & the free-text search words are pre-compiled somewhere. This means I cannot go directly to the sql tables What i'd /love/ to see is something along the lines of: SqlCommand cmd = new SqlCommand("[cy_list_price] > @MinPrice AND [DateOfIntroduction] BETWEEN @StartDate AND @EndDate"); cmd.Parameters.AddWithValue("@MinPrice", 12.99m); cmd.Parameters.AddWithValue("@StartDate", DateTime.Now.AddDays(-2)); cmd.Parameters.AddWithValue("@EndDate", DateTime.Now); CatalogSearch search = /// constructor search.WhereClause = cmd.ToSqlString();

• ASP MVC: Submitting a form with nested user controls

  - by Nigel

  I'm fairly new to ASP MVC so go easy :). I have a form that contains a number of user controls (partial views, as in System.Web.Mvc.ViewUserControl), each with their own view models, and some of those user controls have nested user controls within them. I intended to reuse these user controls so I built up the form using a hierarchy in this way and pass the form a parent view model that contains all the user controls' view models within it. For example: Parent Page (with form and ParentViewModel) -->ChildControl1 (uses ViewModel1 which is passed from ParentViewModel.ViewModel1 property) -->ChildControl2 (uses ViewModel2 which is passed from ParentViewModel.ViewModel2 property) -->ChildControl3 (uses ViewModel3 which is passed from ViewModel2.ViewModel3 property) I hope this makes sense... My question is how do I retrieve the view data when the form is submitted? It seems the view data cannot bind to the ParentViewModel: public string Save(ParentViewModel viewData)... as viewData.ViewModel1 and viewData.ViewModel2 are always null. Is there a way I can perform a custom binding? Ultimately I need the form to be able to cope with a dynamic number of user controls and perform an asynchronous submission without postback. I'll cross those bridges when I come to them but I mention it now so any answer won't preclude this functionality. Many thanks.

• How to convert an InputStream to a DataHandler?

  - by pcorey

  I'm working on a java web application in which files will be stored in a database. Originally we retrieved files already in the DB by simply calling getBytes on our result set: byte[] bytes = resultSet.getBytes(1); ... This byte array was then converted into a DataHandler using the obvious constructor: dataHandler=new DataHandler(bytes,"application/octet-stream"); This worked great until we started trying to store and retrieve larger files. Dumping the entire file contents into a byte array and then building a DataHandler out of that simply requires too much memory. My immediate idea is to retrieve a stream of the data in the database with getBinaryStream and somehow convert that InputStream into a DataHandler in a memory-efficient way. Unfortunately it doesn't seem like there's a direct way to convert an InputStream into a DataHandler. Another idea I've been playing with is reading chunks of data from the InputStream and writing them to the OutputStream of the DataHandler. But... I can't find a way to create an "empty" DataHandler that returns a non-null OutputStream when I call getOutputStream... Has anyone done this? I'd appreciate any help you can give me or leads in the right direction.

• WPF/Silverlight AutoCompleteBox with ability to add new values to list.

  - by WillH

  Hi, I would like to use autocompletebox with a list of values, but also add new values to the list if a user enters one that isn't present. I currently have a string property in my view model called 'Comment'. Currently this is bound to a textbox in the view - user types a comment and the view model is updated. Simple. To save time, my customer would like it to autocomplete from previous values, so the way I thought to do this is something like: ViewModel public string Comment; public ObservableCollection<string> CommentsList { ... } (populate the CommentsList when the viewmodel is created) View <AutoCompleteComboBox ItemsSource="{Binding CommentsList}" SelectedItem="{Binding Comment, Mode=TwoWay/> So when the user selects a value, it saves the value in the Comment property. This works fine if the user selects an item in the list, but if the user types in a new value, the comment property is not updated (it is null because the selected item was not in the list). Is this possible with autocompletebox? Thanks in advance, Will

• SQLiteDataAdapter Fill exception C# ADO.NET

  - by Lirik

  I'm trying to use the OleDb CSV parser to load some data from a CSV file and insert it into a SQLite database, but I get an exception with the OleDbAdapter.Fill method and it's frustrating: An unhandled exception of type 'System.Data.ConstraintException' occurred in System.Data.dll Additional information: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. Here is the source code: public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=No;FMT=Delimited""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); // <-- Exception here InsertData(ds, tableName); // <-- Inserts the data into the my SQLite db } } } class Program { static void Main(string[] args) { SQLiteDatabase target = new SQLiteDatabase(); string csvFileName = "D:\\Innovations\\Finch\\dev\\DataFeed\\YahooTagsInfo.csv"; string tableName = "Tags"; target.InsertData(csvFileName, tableName); Console.ReadKey(); } } The "YahooTagsInfo.csv" file looks like this: tagId,tagName,description,colName,dataType,realTime 1,s,Symbol,symbol,VARCHAR,FALSE 2,c8,After Hours Change,afterhours,DOUBLE,TRUE 3,g3,Annualized Gain,annualizedGain,DOUBLE,FALSE 4,a,Ask,ask,DOUBLE,FALSE 5,a5,Ask Size,askSize,DOUBLE,FALSE 6,a2,Average Daily Volume,avgDailyVolume,DOUBLE,FALSE 7,b,Bid,bid,DOUBLE,FALSE 8,b6,Bid Size,bidSize,DOUBLE,FALSE 9,b4,Book Value,bookValue,DOUBLE,FALSE I've tried the following: Removing the first line in the CSV file so it doesn't confuse it for real data. Changing the TRUE/FALSE realTime flag to 1/0. I've tried 1 and 2 together (i.e. removed the first line and changed the flag). None of these things helped... One constraint is that the tagId is supposed to be unique. Here is what the table look like in design view: Can anybody help me figure out what is the problem here?

• Locking a table for getting MAX in LINQ

  - by Hossein Margani

  Hi Every one! I have a query in LINQ, I want to get MAX of Code of my table and increase it and insert new record with new Code. just like the IDENTITY feature of SQL Server, but here my Code column is char(5) where can be alphabets and numeric. My problem is when inserting a new row, two concurrent processes get max and insert an equal Code to the record. my command is: var maxCode = db.Customers.Select(c=>c.Code).Max(); var anotherCustomer = db.Customers.Where(...).SingleOrDefault(); anotherCustomer.Code = GenerateNextCode(maxCode); db.SubmitChanges(); I ran this command cross 1000 threads and each updating 200 customers, and used a Transaction with IsolationLevel.Serializable, after two or three execution an error occured: using (var db = new DBModelDataContext()) { DbTransaction tran = null; try { db.Connection.Open(); tran = db.Connection.BeginTransaction(IsolationLevel.Serializable); db.Transaction = tran; . . . . tran.Commit(); } catch { tran.Rollback(); } finally { db.Connection.Close(); } } error: Transaction (Process ID 60) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. other IsolationLevels generates this error: Row not found or changed. Please help me, thank you.

• Hadoop streaming with Python and python subprocess

  I have established a basic hadoop master slave cluster setup and able to run mapreduce programs (including python) on the cluster. Now I am trying to run a python code which accesses a C binary and so I am using the subprocess module. I am able to use the hadoop streaming for a normal python code but when I include the subprocess module to access a binary, the job is getting failed.

• Entity Framework with ASP.NET MVC. Updating entity problem

  - by Kitaly

  Hi people. I'm trying to update an entity and its related entities as well. For instance, I have a class Car with a property Category and I want to change its Category. So, I have the following methods in the Controller: public ActionResult Edit(int id) { var categories = context.Categories.ToList(); ViewData["categories"] = new SelectList(categories, "Id", "Name"); var car = context.Cars.Where(c => c.Id == id).First(); return PartialView("Form", car); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Car car) { var category = context.Categories.Where(c => c.Id == car.Category.Id).First(); car.Category = category; context.UpdateCar(car); context.SaveChanges(); return RedirectToAction("Index"); } The UpdateCar method, in ObjectContext class, follows: public void UpdateCar(Car car) { var attachedCar = Cars.Where(c => c.Id == car.Id).First(); ApplyItemUpdates(attachedCar, car); } private void ApplyItemUpdates(EntityObject originalItem, EntityObject updatedItem) { try { ApplyPropertyChanges(originalItem.EntityKey.EntitySetName, updatedItem); ApplyReferencePropertyChanges(updatedItem, originalItem); } catch (InvalidOperationException ex) { Console.WriteLine(ex.ToString()); } } public void ApplyReferencePropertyChanges(IEntityWithRelationships newEntity, IEntityWithRelationships oldEntity) { foreach (var relatedEnd in oldEntity.RelationshipManager.GetAllRelatedEnds()) { var oldRef = relatedEnd as EntityReference; if (oldRef != null) { var newRef = newEntity.RelationshipManager.GetRelatedEnd(oldRef.RelationshipName, oldRef.TargetRoleName) as EntityReference; oldRef.EntityKey = newRef.EntityKey; } } } The problem is that when I set the Category property after the POST in my controller, the entity state changes to Added instead of remaining as Detached. How can I update one-to-one relationship with Entity Framework and ASP.NET MVC without setting all the properties, one by one like this post?

• Distance between Long Lat coord using SQLITE

  - by munchine

  I've got an sqlite db with long and lat of shops and I want to find out the closest 5 shops. So the following code works fine. if(sqlite3_prepare_v2(db, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) { while (sqlite3_step(compiledStatement) == SQLITE_ROW) { NSString *branchStr = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 0)]; NSNumber *fLat = [NSNumber numberWithFloat:(float)sqlite3_column_double(compiledStatement, 1)]; NSNumber *fLong = [NSNumber numberWithFloat:(float)sqlite3_column_double(compiledStatement, 2)]; NSLog(@"Address %@, Lat = %@, Long = %@", branchStr, fLat, fLong); CLLocation *location1 = [[CLLocation alloc] initWithLatitude:currentLocation.coordinate.latitude longitude:currentLocation.coordinate.longitude]; CLLocation *location2 = [[CLLocation alloc] initWithLatitude:[fLat floatValue] longitude:[fLong floatValue]]; NSLog(@"Distance i meters: %f", [location1 getDistanceFrom:location2]); [location1 release]; [location2 release]; } } I know the distance from where I am to each shop. My question is. Is it better to put the distance back into the sqlite row, I have the row when I step thru the database. How do I do that? Do I use the UPDATE statement? Does someone have a piece of code to help me. I can read the sqlite into an array and then sort the array. Do you recommend this over the above approach? Is this more efficient? Finally, if someone has a better way to get the closest 5 shops, love to hear it.

• How to limit speed with BMW JSDK on 116i?

  - by lexicore

  I'm experimenting with the BMW Java SDK on the new BMW 116i Innovation Package. Basic things like turning the lights on and off, starting and stopping the motor work fine. What I'm trying to do now is that to write a carlet which would limit the speed to the maximum configured in the driver profile. Driver identity will be detected as usual via RFID reader. My problem is that though I can read the speed from the tachometer, I can't really limit the speed. Here's what I've got working so far: public class SpeenControllingCarlet extends GenericCarlet { public void start(final VehicleModel model) throws CarletException { RfidReader rfidReader = (RfidReader) model .getDevice(Devices.DRIVER_RFID_READER); Rfid rfid = rfidReader.getRfid(); DriverProfile driverProfile = model.getDriverProfileRegistry() .getDriverProfile(rfid.toString()); if (driverProfile == null) { return; } final Double maxAllowedSpeed = Double.valueOf(driverProfile .getCustomAttribute("maxAllowedSpeed", "190")); Tachometer tachometer = (Tachometer) mode.getDevice(Devices.TACHOMETER); tachometer.addSpeedListener(new SpeedListener() { public void onSpeedChanged(SpeedChangedEvent speedChangedEvent) { if (speedChangedEvent.getCurrentSpeed() > maxAllowedSpeed) { Horn horn = (Horn) mode.getDevice(Devices.HORN); horn.beep(440, 2000); } } }); } } This will just beep for two seconds if the driver goes faster than the driver profile allows. My question is - is there a possibility to actually limit the speed (not just silly beeping)?

• Limit foreign key choices in select in an inline form in admin

  - by mightyhal

  Edited :-) Hopefully a bit clearer now. The logic is of the model is: A Building has many Rooms A Room may be inside another Room (a closet, for instance--ForeignKey on 'self') A Room can only in inside of another Room in the same building (this is the tricky part) Here's the code I have: #spaces/models.py from django.db import models class Building(models.Model): name=models.CharField(max_length=32) def __unicode__(self): return self.name class Room(models.Model): number=models.CharField(max_length=8) building=models.ForeignKey(Building) inside_room=models.ForeignKey('self',blank=True,null=True) def __unicode__(self): return self.number and: #spaces/admin.py from ex.spaces.models import Building, Room from django.contrib import admin class RoomAdmin(admin.ModelAdmin): pass class RoomInline(admin.TabularInline): model = Room extra = 2 class BuildingAdmin(admin.ModelAdmin): inlines=[RoomInline] admin.site.register(Building, BuildingAdmin) admin.site.register(Room) The inline will display only rooms in the current building (which is what I want). The problem, though, is that for the inside_room drop down, it displays all of the rooms in the Rooms table (including those in other buildings). In the inline of rooms, I need to limit the inside_room choices to only rooms which are in the current building being displayed by the main form. I can't figure out a way to do it with either a limit_choices_to in the model, nor can I figure out how exactly to override the admin's inline formset properly (I feel like I should be somehow create a custom inline form, pass the building_id of the main form to the custom inline, then limit the queryset for the field's choices based on that--but I just can't wrap my head around how to do it). Maybe this is too complex for the admin site, but it seems like something that would be generally useful... Thanks again for your help!

• Http Requests POST vs GET

  - by behrk2

  Hi everyone, I am using a lot of HTTP Requests in an application that I am writing which uses OAuth. Currently, I am sending my GET and POST requests the same way: HttpConnection connection = (HttpConnection) Connector.open(url + connectionParameters); connection.setRequestMethod(method); connection.setRequestProperty("WWW-Authenticate", "OAuth realm=api.netflix.com"); int responseCode = connection.getResponseCode(); And this is working fine. I am successfully POSTing and GETing. However, I am worried that I am not doing POST the right way. Do I need to include in the above code the following if-statement? if (method.equals("POST") && postData != null) { connection.setRequestProperty("Content-type", "application/x-www-form-urlencoded"); connection.setRequestProperty("Content-Length", Integer .toString(postData.length)); OutputStream requestOutput = connection.openOutputStream(); requestOutput.write(postData); requestOutput.close(); } If so, why? What's the difference? I would appreciate any feedback. Thanks!

• How to use InterfaceInterceptor with NServiceBus UnityBuilder

  - by David

  I have a MessageHandler with a dependency declared as: public IRepository<Person> PersonRepository {get;set;} I set up my Unity container with: IUnityContainer container = new UnityContainer(); container.AddNewExtension<Interception>(); container.RegisterType(typeof(IRepository<Person>), typeof(Example.Data.InMemory.Repository<Person>)); container.Configure<Interception>() .AddPolicy("PersonAddAdvice") .AddMatchingRule(new AddMatchingRule()) .AddCallHandler(new PersonAddedEventPublishingCallHandler()); container.Configure<Interception>() .SetInterceptorFor<IRepository<Person>>(new InterfaceInterceptor()); Then I Init my endpoint with: class EndpointConfig : IConfigureThisEndpoint, AsA_Publisher, IWantCustomInitialization { public void Init() { NServiceBus.Configure.With() .Log4Net() .UnityBuilder(ContainerConfig.LoadContainer()) .XmlSerializer(); } } (ContainerConfig.LoadContainer() returns the pre-configured IUnityContainer) the problem is that the IRepository dependency in my MessageHandler is not resolved (it's null when handling the messages). If I remove the interception configuration from the Unity container, and simply do this: IUnityContainer container = new UnityContainer(); container.RegisterType(typeof(IRepository<Person>), typeof(Example.Data.InMemory.Repository<Person>)); It works as expected, and the MessageHandler has an instance if IRepository resolved.

• Dojo: Programatically setting checkbox label for adding on TableContainer

  - by Det

  Hi there, after some hours of checking out documentation, I am somewhat desperate: Basically I need to populate a TabContainer with some TextBoxes, and some Checkboxes. All theses neatly arranged: Labels to the left, fields to the right. To have this done I use a TableContainer that I add to the TabContainer, create the TextFields and add them to the TableContainer. All is rendered ok. But when it comes to a checkbox, I can't find the trick to have a label displayed at all. If I: - add a label-attribute to creation statement say: var text8 = new dijit.form.CheckBox({ id:"zuschauer_" + i, value: "zuschauer", label:"fritt"}); Firefox comes up with a "containerNode is null" - Error try to add a tag: Nothing is shown (no error, but alas: no label): var text9 = dojo.create('<label>'); dojo.attr(text9,"for","zuschauer_" + i); dojo.attr(text9,"content","fritt"); try to add a div or somewhat else on the tablecontainer (disabled Labels): Firefox comes up whith: Error: uncaught exception: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER) [nsIDOMHTMLDivElement.appendChild]" nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame :: ... same is for created TextNodes... So how the hack: - Would I generate a label to a checkbox programatically (no html template possible, I've seen the code around, creating a checkbox but having a 'label for' on the html before. This would not be helpful, as I don't know how many checkboxes I need at designtime. These are to be genereated completly at runtime. - Would I have this very simple design done programatically, Must be easy, this is not rocket sience. Do I really need the TableContainer to have this done? - Can I create static text in a TableContainer? Any hint would be helpful Desperate Det

• Adding a UITapGestureRecognizer to a view then removing seems to short circuit button events

  - by heymon

  In the code below I am popping up a ImageView as the result of a users touchUpInside on a simple info button. There are other buttons on the view. To dismiss the info I added a UITapGestureRecognizer to my controllers view, and hide the view when the tap is detected. If I don't remove the tapGestureRecognizer, the action is called every time some. Even when I do remove the gesture action, no bottons receive touchUpInside events once this gesture recognizer is added. Why? Code from my MainViewController (void) dismissInfo: (UITapGestureRecognizer *)gesture { [kInfoView setHidden: YES]; [gesture removeTarget: self action: NULL]; } (IBAction) displayInfo { CGRect startFrame = CGRectMake(725, 25, 0, 0), origFrame; CGFloat yCenter = [kInfoView frame].size.height/2 + 200; CGPoint startCenter = CGPointMake(724, 25), displayCenter = CGPointMake(384, yCenter); UITapGestureRecognizer *g = [[UITapGestureRecognizer alloc] initWithTarget: self action: @selector(dismissInfo:)]; [self.view addGestureRecognizer: g]; origFrame = [kInfoView frame]; [kInfoView setCenter: startCenter]; [kInfoView setHidden: NO]; [kInfoView setFrame: startFrame]; [UIView beginAnimations: @"info" context: nil]; [UIView setAnimationDuration: .5]; [UIView setAnimationDelegate: self]; [kInfoView setFrame: origFrame]; [kInfoView setCenter: displayCenter]; [UIView commitAnimations]; }

• How to set focus to a brand new TextBox which was created as a result of a databinding in WPF?

  - by Mike

  Hi everyone, I have a WPF ItemsControl that is bound to an ObservableCollection. The XAML: <ItemsControl Name="mItemsControl"> <ItemsControl.ItemTemplate> <DataTemplate> <TextBox Text="{Binding Mode=OneWay}"></TextBox> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> The codebehind: private ObservableCollection<string> mCollection = new ObservableCollection<string>(); public MainWindow() { InitializeComponent(); this.mCollection.Add("Test1"); this.mCollection.Add("Test2"); this.mItemsControl.ItemsSource = this.mCollection; } private void Button_Click(object sender, RoutedEventArgs e) { this.mCollection.Add("new item!"); } When I click a button, it adds a new string to the databound ObservableCollection which triggers a new TextBox to appear. I want to give this new textbox focus. I've tried this technique from a related StackOverflow question but it always sets focus to the textbox before the newly created one. private void Button_Click(object sender, RoutedEventArgs e) { this.mCollection.Add("new item!"); // MoveFocus takes a TraversalRequest as its argument. TraversalRequest request = new TraversalRequest(FocusNavigationDirection.Previous); // Gets the element with keyboard focus. UIElement elementWithFocus = Keyboard.FocusedElement as UIElement; // Change keyboard focus. if (elementWithFocus != null) { elementWithFocus.MoveFocus(request); } } My need seems simple enough, but it's almost like the new textbox doesn't really exist until a slight delay after something is added to the ObservableCollection. Any ideas of what would work? Thanks! -Mike

• Why can't the compiler/JVM just make autoboxing "just work"?

  - by Pyrolistical

  Autoboxing is rather scary. While I fully understand the difference between == and .equals I can't but help have the follow bug the hell out of me: final List<Integer> foo = Arrays.asList(1, 1000); final List<Integer> bar = Arrays.asList(1, 1000); System.out.println(foo.get(0) == bar.get(0)); System.out.println(foo.get(1) == bar.get(1)); That prints true false Why did they do it this way? It something to do with cached Integers, but if that is the case why don't they just cache all Integers used by the program? Or why doesn't the JVM always auto unbox to primitive? Printing false false or true true would have been way better. EDIT I disagree about breakage of old code. By having foo.get(0) == bar.get(0) return true you already broke the code. Can't this be solved at the compiler level by replacing Integer with int in byte code (as long as it is never assigned null)

• Is android's motion event handling accurate??

  - by Peterdk

  Bug I have a weird bug in my piano app. Sometimes keys (and thus notes) hang. I did a lot of debugging and narrowed it down to what looks like androids inaccuracy of motion event handling: DEBUG/(2091): ACTION_DOWN A4 DEBUG/(2091): KeyDown: A4 DEBUG/(2091): ACTION_MOVE A4 => A4 DEBUG/(2091): ACTION_MOVE ignoring DEBUG/(2091): ACTION_MOVE A4 => A4 DEBUG/(2091): ACTION_MOVE ignoring DEBUG/(2091): ACTION_MOVE A4 => A4 DEBUG/(2091): ACTION_MOVE ignoring DEBUG/(2091): ACTION_UP B4 //HOW CAN THIS BE???? DEBUG/(2091): KeyUp: B4 DEBUG/(2091): Stream is null, can't stop DEBUG/(2091): Hanging Note: A4 X=240-287 EventX=292 Y=117-200 EventY=164 DEBUG/(2091): KeyUp Note: B4 X=288-335 EventX=292 Y=117-200 EventY=164 Clearly it can be seen here that out of nowhere I suddenly have an ACTION_UP for another note. Shouldn't I definitely get a ACTION_MOVE first? As shown in the end of the log, it's definitely not an error in region detection, since the ACTION_UP event is clearly in the B4 region. Logging Implementation details Every onTouchEvent() call is logged, so the log is accurate. The relevant pseudo-code for the ACTION_MOVE logging is: Key oldKey = Key.get(event.getHistoricalX(), event.getHistoricalY()); Key newKey = Key.get(event.getX(), event.getY()); Question Is this normal behaviour for Android (the jumping in coordinates)? Am I missing something?
