• Why I add the CGPoint in the NSMultable Array?

  - by Tattat

  I want to store my CGPoint to the NSMultable Array, so , I have method like this: [self.points addObject:CGPointMake(x, y)]; But I got the error, it said that : Incompatible type for argument 1 of "addObject". So, I check out the API, (void)addObject:(id)anObject anObject The object to add to the end of the receiver's content. This value must not be nil. So, I think the "CGPointMake" can make a Object, but it can't be assigned. What happens?

• How to register a custom type in Hibernate using org.springframework.orm.hibernate4.LocalSessionFactoryBean

  - by Luis

  I'm migrating from hibernate 3 to hibernate 4, In hibernate 3 the way I was registering a custom type was: public class AnnotationSessionFactoryBean extends org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean { private Collection<? extends BasicType> customTypes; public Collection<? extends BasicType> getCustomTypes() { return customTypes; } public void setCustomTypes(Collection<? extends BasicType> customTypes) { this.customTypes = customTypes; } @Override protected Configuration newConfiguration() throws HibernateException { Configuration configuration = super.newConfiguration(); if (CollectionUtils.hasEntries(customTypes)) { for (BasicType customType:customTypes) { configuration.registerTypeOverride(customType); } } return configuration; }} I'm now trying to do the same operation but using hibernate 4, my question is how is the best way to do this? since I dont have access do change configuration when using "org.springframework.orm.hibernate4.LocalSessionFactoryBean" instead of "org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean". Thanks

• Why does this XML validation via XSD fail in libxml2 (but succeed in xmllint) and how do I fix it?

  - by mtree

• UICollectionViewController nested in a normal UIViewController

  - by patrickS

  I have added a UICollectionView into a normal ViewController (MainViewController), and than created a UICollectionViewController Subclass (CollectionViewController) in the ViewController and connected the UICollectionView outlet with the CollectionViewController object _collectionViewController = [[CollectionViewController alloc] initWithCollectionViewLayout:_collectionView.collectionViewLayout]; _collectionView.dataSource = _collectionViewController; _collectionView.delegate = _collectionViewController; In the CollectionViewController I have setup an simple NSArray object and I show this one. This works as expected. But If I try to access the collectionview from the CollectionViewController via self.collectionview I am not able to access this one. I dont know what I have to do, to also connect the collectionview. I have build a sample ios-app it is available at: https://github.com/patricks/uicollectionview-problem The method - (void)outputSelectedCell in the UICollectionViewController always shows, that there is nothing selected… I hope you understand the problem.

• Event handler of Dropdownlist inside Gridview

  - by hotcoder

  I've added Dropdownlist in Gridview at RowDataBound event. The code is: if (e.Row.RowType == DataControlRowType.DataRow) { DropDownList ddlSeason = new DropDownList(); ddlSeason.DataSourceID = "odsRoomSeason"; ddlSeason.DataTextField = "SeasonTittle"; ddlSeason.DataValueField = "SeasonID"; ddlSeason.AutoPostBack = true; ddlSeason.SelectedIndexChanged += new EventHandler(ddlSeason_SelectedIndexChanged); TableCell tcSeason= new TableCell(); tcSeason.Controls.Add(ddlSeason); e.Row.Cells.AddAt(e.Row.Cells.Count, tcSeason); } The event handler I've added is: protected void ddlSeason_SelectedIndexChanged(object sender, EventArgs e) { // } But the problem is that the event handler function doesn't catch the event. Please tell me how to write the correct event handler, also I need to get the row from which the Dropdownlist's event has fired.

• GLTessellator crashing

  - by user146780

  I'v followed a tutorial to get the GLU tesselator working. It woulds except the interpolation for colors of new points causes a crash (error reading from memory...) This is my callback where it crashes: void CALLBACK combineCallback(GLdouble coords[3], GLdouble *vertex_data[4], GLfloat weight[4], GLdouble **dataOut) { GLdouble *vertex; int i; vertex = (GLdouble *) malloc(6 * sizeof(GLdouble)); vertex[0] = coords[0]; vertex[1] = coords[1]; vertex[2] = coords[2]; //crashes here **for (int i = 3; i < 6; i++) { vertex[i] = weight[0] * vertex_data[0][i] + weight[1] * vertex_data[1][i] + weight[2] * vertex_data[2][i] + weight[3] * vertex_data[3][i]; }** //crashes here *dataOut = vertex; } I looked at memory when it crashes but can't put my finger on exactly what triggers it. I followed this tutorial: http://www.flipcode.com/archives/Polygon_Tessellation_In_OpenGL.shtml Thanks

• problem with adding tool bar to UITableView

  - by chnet

  I'm writing a Navigation-Based iPhone app, and I'd like to have a UIToolBar docked at the bottom of my screen, with a UITableView scrolling between the tool bar and the navigation bar. I used [[self navigationController] setToolbarHidden:NO] and - (void)setToolbarItems:(NSArray *)toolbarItems animated:(BOOL)animated to set the UIToolBar. UIToolBar correctly shows in current view. If I drill down into a detail view using the button on navigation bar, i cannot return back to previous view. Before I add the tool bar, it can return back. I am wondering is there anything else should be noted when use UIToolbar?

• Is WPF Decorator class useful?

  - by darja

  I need to create control to draw border around its child. So, I have created class and derived it from Decorator: class RoundedBoxDecorator : Decorator { protected override Size ArrangeOverride(Size arrangeSize) { //some source } protected override void OnRender(DrawingContext dc) { //some source } } It works fine, but I have some doubts about using Decorator as ancestor. I have found in MSDN that there are no special methods or properties in it, only derived from its ancestors (UIElement or FrameworkElement). ArrangeOverride and OnRender are also derived. So, what for Decorator class was designed and does it makes sense to use it? Or I can derive from FrameworkElement?

• C# thread with multiple parameters

  - by Lucas B

  Does anyone know how to pass multiple parameters into a Thread.Start routine? I thought of extending the class, but the C# Thread class is sealed. Here is what I think the code would look like: ... Thread standardTCPServerThread = new Thread(startSocketServerAsThread); standardServerThread.Start( orchestrator, initializeMemberBalance, arg, 60000); ... } static void startSocketServerAsThread(ServiceOrchestrator orchestrator, List<int> memberBalances, string arg, int port) { startSocketServer(orchestrator, memberBalances, arg, port); } Thank you in advance. BTW, I start a number of threads with different orchestrators, balances and ports. Please consider thread safety also.

• Cant get the catch statement to catch the custom exception

  - by user282807

  i have created a custom exception in the business layer and also using wcf layer where I am calling the methods in the business layer then in another website i am calling the method from wcf. i can see the message that i wrote in custom exception but the program goes staright to exception (the second catch block) instead of hitting my first catch block(where the custom exception is) when i hover over the exception i see my message but it's inside something called faultexception which i am not familiar with. and in there under details..there i see type= CanOnlyApplyOnceException. here is my code: protected void AddNewApplication() { try { using (var proxy = new ServiceReference1.ServiceClient()) { proxy.AddApplication(new Application { Credentials = 2, Comments = txtComments.Text, }); } } catch (CanOnlyApplyOnceException c) { ErrorSummary.AddError(c.Message, this); return; } catch (Exception) { lblStatus.Text = "There has been an error. Please try again"; } }

• Java: what are IOEXceptions in BufferedReader's readLine() for?

  - by HH

  I can "fix" the below exception with a try-catch loop but I cannot understand the reason. Why does the part "in.readLine()" continuosly ignite IOExceptions? What is really the purpose of throwing such exceptions, the goal probably not just more side effects? Code and IOExceptions $ javac ReadLineTest.java ReadLineTest.java:9: unreported exception java.io.IOException; must be caught or declared to be thrown while((s=in.readLine())!=null){ ^ 1 error $ cat ReadLineTest.java import java.io.*; import java.util.*; public class ReadLineTest { public static void main(String[] args) { String s; BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); // WHY IOException here? while((s=in.readLine())!=null){ System.out.println(s); } } }

• Compiling Scala scripts. How works scalac?

  - by Arturo Herrero

  Groovy Groovy comes with a compiler called groovyc. For each script, groovyc generates a class that extends groovy.lang.Script, which contains a main method so that Java can execute it. The name of the compiled class matches the name of the script being compiled. For example, with this HelloWorld.groovy script: println "Hello World" That becomes something like this code: class HelloWorld extends Script { public static void main(String[] args) { println "Hello World" } } Scala Scala comes with a compiler called scalac. I don't know how it works. For example, with the same HelloWorld.scala script: println("Hello World") The code is not valid for scalac, because the compiler expected class or object definition, but works in Scala REPL interpreter. How is possible? Is it wrapped in a class before execution?

• Help with hash tables and quadratic probing in Java

  - by user313458

  I really need help with inserting into a hash table. I'm just not totally getting it right now. Could someone explain quadratic and linear probing in layman's terms? public void insert(String key) { int homeLocation = 0; int location = 0; int count = 0; if (find(key).getLocation() == -1) // make sure key is not already in the table { //****** ADD YOUR CODE HERE FOR QUADRATIC PROBING ******** } } This is the code I'm working on. I'm not asking anyone to do it, I just really need help with learning the whole concept Any help would be greatly appreciated.

• jaxb XmlAccessType: PROPERTY example

  - by Bjorn J

  I'm trying to use jaxb and want to use the 'XmlAccessType.PROPERTY' to let jaxb use getters/setters rather than variable directly, but get different errors depending on what I try, or the variable isn't set at all like I want. Any good link or pointer to a simple example? For example, the below makes the groupDefintion not to be set when parsing the xml document: @XmlAccessorType(javax.xml.bind.annotation.XmlAccessType.PROPERTY) public class E { private EGroup groupDefinition; public EGroup getGroupDefinition () { return groupDefinition; } @XmlAttribute public void setGroupDefinition (EGroup g) { groupDefinition = g; } }

• Using jquery to make a POST, how to properly supply 'data' parameter?

  - by user246114

  Hi, I'd like to make an ajax call as a POST, it's going to go to my servlet. I want to send parameterized data, like the following: var mydata = 'param0=some_text&param1=some_more_text'; I supply this as the 'data' parameter of my jquery ajax() call. So this should be inserted in the body of the POST, right? (I mean, not appended to my 'mysite/save' url?): $.ajax({ url: 'mysite/save', type: 'POST', data: mydata }); it appears to work correctly. In my servlet, I am just dumping all received parameters, and I see them all come through nicely: private void printParams(HttpServletRequest req) { Enumeration paramNames = req.getParameterNames(); while (paramNames.hasMoreElements()) { // print each param key/val here. } } also, I should url encode my data string manually before use, right? Like: var mydata = 'param0=' + urlencode('hi there!'); mydata += '&param1=' + urlencode('blah blah'); mydata += '%param2=' + urlencode('we get it'); Thanks!

• SqlCommand() ExecuteNonQuery() truncates command text.

  - by H. Abraham Chavez

  I'm building a custom db deployment utility, I need to read text files containing sql scripts and execute them against the database. Pretty easy stuff, so far so good. However I've encountered a snag, the contents of the file are read successfully and entirely, but once passed into the SqlCommand and then executed with SqlCommand.ExecuteNonQuery only part of the script is executed. I fired up Profiler and confirmed that my code is not passing all of the script. private void ExecuteScript(string cmd, SqlConnection sqlConn, SqlTransaction trans) { SqlCommand sqlCmd = new SqlCommand(cmd, sqlConn, trans); sqlCmd.CommandType = CommandType.Text; sqlCmd.CommandTimeout = 9000000; // for testing sqlCmd.ExecuteNonQuery(); } // I call it like this, readDMLScript contains 543 lines of T-SQL string readDMLScript = ReadFile(dmlFile); ExecuteScript(readDMLScript, sqlConn, trans);

• Unable to forward UITouch events to my view controller

  - by hyn

  I have a UISplitViewController setup with a custom view added as a subview of the view (UILayoutContainerView) of split view controller. I am trying to forward touch events from my custom view controller to the master and detail views, but the following (which was suggested here on another thread) seems to have no effect: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; // Do something [self.nextResponder touchesBegan:touches withEvent:event]; } (I couldn't get this formatted properly) As a result my custom view controller locks the events and all the UI underneath never has a chance to do anything. How can I get my master and detail view controllers to receive events?

• using document.createDocumentFragment() child dom elements that contain jQuery.data

  - by taber

  I want to use document.createDocumentFragment() to create an optimized collection of HTML elements that contain ".data" coming from jQuery (v 1.4.2), but I'm kind of stuck on how to get the data to surface from the HTML elements. Here's my code: var genres_html = document.createDocumentFragment(); $(xmlData).find('genres').each(function(i, node) { var genre = document.createElement('a'); $(genre).addClass('button') .attr('href', 'javascript:void(0)') .html( $(node).find('genreName:first').text() ) .data('genreData', { id: $(node).find('genreID:first').text() }); genres_html.appendChild( genre.cloneNode(true) ); }); $('#list').html(genres_html); // error: $('#list a:first').data('genreData') is null alert($('#list a:first').data('genreData').id); What am I doing wrong here? I suspect it's probably something with .cloneNode() not carrying over the data when the element is appended to the documentFragment. Sometimes there are tons of rows so I want to keep things pretty optimized, speed-wise. Thanks!

• Registering NUnit DynamicMock Instances in a UnityContainer

  - by Phil

  I'm somewhat new to Unity and dependency injection. I'm trying to write a unit test that goes something like this: [Test] public void Test() { UnityContainer container = new UnityContainer(); DynamicMock myMock = new DynamicMock(typeof(IMyInterface)); container.RegisterInstance(typeof(IMyInterface), myMock.MockInstance); //Error here // Continue unit test... } When this test executes, the container throws an ArgumentNullException inside the RegisterInstance method with the message Value cannot be null. Parameter name: assignmentValueType. The top line of the stack trace is at Microsoft.Practices.Unity.Utility.Guard.TypeIsAssignable(Type assignmentTargetType, Type assignmentValueType, String argumentName). Why can't I register a MockInstance with the UnityContainer, and how do I work around this?

• How to add custom hooks to controllers in ASP.NET MVC2

  - by Adrian

  Hi, I've just started a new project in ASP.net 4.0 with MVC 2. What I need to be able to do is have a custom hook at the start and end of each action of the controller. e.g. public void Index() { *** call to the start custom hook to externalfile.cs (is empty so does nothing) ViewData["welcomeMessage"] = "Hello World"; *** call to the end custom hook to externalfile.cs (changes "Hello World!" to "Hi World") return View(); } The View then see welcomeMessage as "Hi World" after being changed in the custom hook. The custom hook would need to be in an external file and not change the "core" compiled code. This causes a problem as with my limited knowledge ASP.net MVC has to be compiled. Does anyone have any advice on how this can be achieved? Thanks

• Multiple Condition Coverage Testing

  Hi Folks, When using the White Box method of testing called Multiple Condition Coverage, do we take all conditional statements or just the ones with multiple conditions? Now maybe the clues in the name but I'm not sure. So if I have the following method void someMethod() { if(a && b && (c || (d && e)) ) //Conditional A { } if(z && q) // Conditional B { } } Do I generate the truth table for just "Conditional A", or do I also do Conditional B? Thanks,
