  • Problem with tcp server when converting to service

    - by djerry
    Hello lads, I'm working on monitoring some object (cdr-packets). I'm setting up a tcp-server and am listening on port 50043 for the packages. The program as a console application is working just fine, my server is working like it should and i'm receiving the packets. When i try to use it as a service, i cannot seem to get a client connected to my server. Is there something i need to change to deploy this as a service? Code below is from my application: this is my service class where i start protected override void OnStart(string[] args) { server = new TcpServer(); server.StartServer(); } this is the constructor of TcpServer public TcpServer() { try { _server = new TcpListener(IPAddress.Any, 50043); } catch (Exception) { _server = null; } } this is the method i call after initialising the class public void StartServer() { if (_server != null) { // Create a ArrayList for storing SocketListeners before starting the server. _socketListenersList = new ArrayList(); // Start the Server and start the thread to listen client requests. _server.Start(); _serverThread = new Thread(new ThreadStart(ServerThreadStart)); _serverThread.Start(); // Create a low priority thread that checks and deletes client // SocktConnection objcts that are marked for deletion. _purgingThread = new Thread(new ThreadStart(PurgingThreadStart)); _purgingThread.Priority = ThreadPriority.Lowest; _purgingThread.Start(); } } this is the thread that keep checking if any client tries to connect private void ServerThreadStart() { // Client Socket variable; Socket clientSocket = null; TcpSocketListener socketListener = null; while (!_stopServer) { try { // Wait for any client requests and if there is any request from any //client accept it (Wait indefinitely). clientSocket = _server.AcceptSocket(); // Create a SocketListener object for the client. socketListener = new TcpSocketListener(clientSocket); // Add the socket listener to an array list in a thread safe fashon. lock (_socketListenersList) { _socketListenersList.Add(socketListener); } // Start a communicating with the client in a different thread. socketListener.StartSocketListener(); } catch (SocketException se) { _stopServer = true; } } } when for the first time a packet waits to be read, and i get to "clientSocket = _server.AcceptSocket();", it throws an exception (service, not very good debugable) Does anyone recognize this problem or can help me? Thanks in advance

  • Publish to Facebook Stream via PHP using Graph API

    - by Liquid
    I'm trying to post a message to a user's wall using the new graph API and PHP. Connection seems to work fine, but no post appears. I'm not sure how to set up the posting code correctly. Please help me out. Sorry for the broken-looking code, for some reason StackOverflow didn't want to close it all in the code block. Below is my full code. Am I missing an extender permission requests, or is that taken care in this code: PHP Code <?php include_once 'facebook.php'; $facebook = new Facebook(array( 'appId' => 'xxxxxxxxxxxxxxxxxx', 'secret' => 'xxxxxxxxxxxxxxxxxxxxxxxxxx', 'cookie' => true )); $session = $facebook->getSession(); if (!$session) { $url = $facebook->getLoginUrl(array( 'canvas' => 1, 'fbconnect' => 0 )); echo "<script type='text/javascript'>top.location.href = '$url';</script>"; } else { try { $uid = $facebook->getUser(); $me = $facebook->api('/me'); $updated = date("l, F j, Y", strtotime($me['updated_time'])); echo "Hello " . $me['name'] .

  • Stretch panel with splitter

    - by user1153896
    I want to implement a basic WPF layout with three panels and two splitters (Horizontal and Vertical splitter). Two panels on the left and on the bottom has to be callapsable and one panel has to stretch accordingly. Here is a simple XAML: <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="5"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <StackPanel Background="Aqua" Grid.Column="0" Name="leftPanel" > <TextBlock FontSize="35" Foreground="#58290A" TextWrapping="Wrap">Left Hand Side</TextBlock> </StackPanel> <GridSplitter Grid.Column="1" HorizontalAlignment="Stretch"/> <Grid Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="5" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Label Content="... Clien Area .. Has to Stretch vertically and horizontally" Margin="10"></Label> <Button Click="LeftButton_Click" Margin="10">Close Left Panel</Button> <Button Click="BottomButton_Click" Margin="10">Close Bottom Panel</Button> </StackPanel> <GridSplitter Grid.Row="1" Background="Gray" HorizontalAlignment="Stretch"/> <ListBox Grid.Row="2" Background="Violet" Name="bottomPanel"> <ListBoxItem>Hello</ListBoxItem> <ListBoxItem>World</ListBoxItem> </ListBox> </Grid> </Grid> and codebehind: private void LeftButton_Click(object sender, RoutedEventArgs e) { leftPanel.Visibility = (leftPanel.Visibility == System.Windows.Visibility.Visible)? System.Windows.Visibility.Collapsed : System.Windows.Visibility.Visible; } private void BottomButton_Click(object sender, RoutedEventArgs e) { bottomPanel.Visibility = (bottomPanel.Visibility == System.Windows.Visibility.Visible) ? System.Windows.Visibility.Collapsed : System.Windows.Visibility.Visible; } This code doesn't work as expected :(. Any WPF experts around? to suggest a solution for having Client Area (stretched) and splitter at the same time? DockPanel will work perfectly, but I need splitter! Thanks.

  • Understanding C++ dynamic allocation

    - by kiokko89
    Consider the following code: class CString { private: char* buff; size_t len; public: CString(const char* p):len(0), buff(nullptr) { cout << "Constructor called!"<<endl; if (p!=nullptr) { len= strlen(p); if (len>0) { buff= new char[len+1]; strcpy_s(buff, len+1, p); } } } CString (const CString& s) { cout << "Copy constructor called!"<<endl; len= s.len; buff= new char[len+1]; strcpy_s(buff, len+1, s.buff); } CString& operator = (const CString& rhs) { cout << "Assignment operator called!"<<endl; if (this != &rhs) { len= rhs.len; delete[] buff; buff= new char[len+1]; strcpy_s(buff, len+1, rhs.buff); } return *this; } CString operator + (const CString& rhs) const { cout << "Addition operator called!"<<endl; size_t lenght= len+rhs.len+1; char* tmp = new char[lenght]; strcpy_s(tmp, lenght, buff); strcat_s(tmp, lenght, rhs.buff); return CString(tmp); } ~CString() { cout << "Destructor called!"<<endl; delete[] buff; } }; int main() { CString s1("Hello"); CString s2("World"); CString s3 = s1+s2; } My problem is that I don't know how to delete the memory allocated in the addition operator function(char* tmp = new char[length]). I couldn't do this in the constructor(I tried delete[] p) because it is also called from the main function with arrays of chars as parameters which are not allocated on the heap...How can I get around this? (Sorry for my bad English...)

  • CoreData : App crashes when deleting last instance created

    - by Leo
    Hello, I have a 2 tabs application. In the first one, I'm creating objects of the "Sample" and "SampleList" entities. Each sampleList contains an ID and a set of samples. Each sample contains a date and temperature property. In the second tab, I'm displaying my data in a tableView. I implemented the - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath method in order to delete SampleLists. In my xcdatamodel the delete rule for my relationship between SampleList and Sample is Cascade. My problem is that when I try to delete SampleList I just created, the app crashes and I receive a EXC_BAD_ACCESS signal. If I restart it, then I'm able to delete "old" sampleList without any problems. Earlier, I had the following problem : I couldn't display the the sampleLists I created since I launched the app, because it crashed too. I received also the EXC_BAD_ACCESS signal. Actually, it seemed that the date of the last sample created of the set was nil. If I am not releasing the NSDate I'm using to set the sample's date, I don't have this problem anymore... If anyone could help me to find out what could cause my troubles it would be great !! Here is the method I'm using to create new instances : SampleList *newSampleList = (SampleList *)[NSEntityDescription insertNewObjectForEntityForName:@"SampleList" inManagedObjectContext:managedObjectContext]; [newSampleList setPatchID:patchID]; NSMutableSet *newSampleSet = [[NSMutableSet alloc] init]; NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; for (int i = 0; i < [byteArray count]; i=i+4, sampleCount++) { NSDateComponents *comps = [[NSDateComponents alloc] init]; [comps setYear:year]; [comps setMonth:month]; [comps setDay:day]; [comps setHour:hours]; [comps setMinute:minutes]; NSDate *sampleDate = [gregorian dateFromComponents:comps]; Sample *newSample = (Sample *)[NSEntityDescription insertNewObjectForEntityForName:@"Sample" inManagedObjectContext:managedObjectContext]; [newSample setSampleDate:sampleDate]; [newSample setSampleTemperature:[NSNumber numberWithInt:temperature]]; [newSampleSet addObject:newSample]; [comps release]; //[sampleDate release]; } [newSampleList setSampleSet:newSampleSet]; // [newSampleSet release]; NSError *error; if (![managedObjectContext save:&error]) { NSLog(@"Could not Save the context !!"); } [gregorian release];

  • QTreeView memory consumption

    - by Eye of Hell
    Hello. I'm testing QTreeView functionality right now, and i was amazed by one thing. It seems that QTreeView memory consumption depends on items count O_O. This is highly unusual, since model-view containers of such type only keeps track for items being displayed, and rest of items are in the model. I have written a following code with a simple model that holds no data and just reports that it has 10 millions items. With MFC, Windows API or .NET tree / list with such model will take no memory, since it will display only 10-20 visible elements and will request model for more upon scrolling / expanding items. But with Qt, such simple model results in ~300Mb memory consumtion. Increasing number of items will increase memory consumption. Maybe anyone can hint me what i'm doing wrong? :) #include <QtGui/QApplication> #include <QTreeView> #include <QAbstractItemModel> class CModel : public QAbstractItemModel { public: QModelIndex index ( int i_nRow, int i_nCol, const QModelIndex& i_oParent = QModelIndex() ) const { return createIndex( i_nRow, i_nCol, 0 ); } public: QModelIndex parent ( const QModelIndex& i_oInex ) const { return QModelIndex(); } public: int rowCount ( const QModelIndex& i_oParent = QModelIndex() ) const { return i_oParent.isValid() ? 0 : 1000 * 1000 * 10; } public: int columnCount ( const QModelIndex& i_oParent = QModelIndex() ) const { return 1; } public: QVariant data ( const QModelIndex& i_oIndex, int i_nRole = Qt::DisplayRole ) const { return Qt::DisplayRole == i_nRole ? QVariant( "1" ) : QVariant(); } }; int main(int argc, char *argv[]) { QApplication a(argc, argv); QTreeView oWnd; CModel oModel; oWnd.setUniformRowHeights( true ); oWnd.setModel( & oModel ); oWnd.show(); return a.exec(); }

  • Multi-Threading Question Concerning WPF

    - by Andrew
    Hello, I'm a newbie to threading, and I don't really know how to code a particular task. I would like to handle a mouse click event on a window that will kick off a while loop in a seperate thread. This thread, which is distinct from the UI thread, should call a function in the while loop which updates a label on the window being serviced by the UI thread. The while loop should stop running when the left mouse button is no longer being pressed. All the loop does is increment a counter, and then repeatedly call the function which displays the updated value in the window. The code for the window and all of the threading is given below (I keep getting some error about STA threading, but don't know where to put the attribute). Also, I'm hoping to use this solution, if it ever works, in another project that makes asynchronous calls elsewhere to a service via wcf, so I was hoping not to make any application-wide special configurations, since I'm really new to multi-threading and am quite worried about breaking other code in a larger program... Here's what I have: <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication2" Name="MyMainWindow" Title="MainWindow" Width="200" Height="150" PreviewMouseLeftButtonDown="MyMainWindow_PreviewMouseLeftButtonDown"> <Label Height="28" Name="CounterLbl" /> </Window> And here's the code-behind: using System.Windows; using System.Windows.Input; using System.Threading; namespace WpfApplication2 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { private int counter = 0; public MainWindow() { InitializeComponent(); } private delegate void EmptyDelegate(); private void MyMainWindow_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e) { Thread counterThread = new Thread(new ThreadStart(MyThread)); counterThread.Start(); } private void MyThread() { while (Mouse.LeftButton == MouseButtonState.Pressed) { counter++; Dispatcher.Invoke(new EmptyDelegate(UpdateLabelContents), null); } } private void UpdateLabelContents() { CounterLbl.Content = counter.ToString(); } } } Anyways, multi-threading is really new to me, and I don't have any experience implementing it, so any thoughts or suggestions are welcome! Thanks, Andrew

  • Re-Add tabBarController's view into window and the device is in landscape mode

    - by user285553
    Hello, I have an app that is a tabBarController based app. I have 4 tabs on it and one of these is for logging in/out in my app. The main ideea is that when I logout, I release the tabBarController (this will release the all 4 view controllers too - I have done this becuse I want to refersh all the views after logging out to look just like the first time).After this, I alloc it again and add the view controllers aagin,set the tabBarItem's titles,etc.This work ok. The problem is when I am in landscape mode;my logout view is painted to fit the landscape area,but after disconnect(now I releasse and alloc again the tabbarController) the view is painted in portrait mode but my device is in lanscape. After disconnected, I call the releaseOldTabView and the createNewTabView.After this tabBarController is in portrait insead of landscape. -(void)releaseOldTabView:(BOOL)tabViewEnabled{ if(tabViewEnabled){ [tabBarController.view removeFromSuperview]; [tabBarController release]; } } -(void)createNewTabView{ tabBarController = [[UITabBarController alloc] init]; NSMutableArray *oneArray = [[NSMutableArray alloc] init]; tabBarController.delegate = self; LoginViewController *login= [[LoginViewController2 alloc] initWithNibName:@"LoginViewController" bundle:nil]; SecondViewController *secondController = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; ThirdViewController *thirdController = [[ThirdViewController alloc] init]; FourthViewController *fourthController = [[FourthViewController alloc] init]; login.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"Login" image:[UIImage imageNamed:@"connect.png"] tag:0]; secondController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"TabBar2" image:[UIImage imageNamed:@"tabBar2.png"] tag:1]; thirdController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"TabBar3" image:[UIImage imageNamed:@"tabBar3.png"] tag:2]; fourthController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"TabBar4" image:[UIImage imageNamed:@"tabBar4.png"] tag:3]; [oneArray addObject:login]; [oneArray addObject:secondController]; [oneArray addObject:thirdController]; [oneArray addObject:fourthController]; [tabBarController setViewControllers:oneArray]; //[tabBarController.view convertRect:tabBarController.view.frame toView:window]; [window addSubview:tabBarController.view]; [oneArray release]; [login release]; [secondController release]; [thirdController release]; [fourthController release]; } After calling this method, the tabbar view is in portrait,but statusBar(the top bar which says the carrier name) is painted normally(landscape). I also tried the [tabBarController.view convertRect:tabBarController.view.frame toView:window]; but without any succes. Can anyone give a hand of help? Thanks in advance, Alex.

  • HLSL tex2d sampler seemingly using inconsistent rounding; why?

    - by RJFalconer
    Hello all, I have code that needs to render regions of my object differently depending on their location. I am trying to use a colour map to define these regions. The problem is when I sample from my colour map, I get collisions. Ie, two regions with different colours in the colourmap get the same value returned from the sampler. I've tried various formats of my colour map. I set the colours for each region to be "5" apart in each case; Indexed colour RGB, RGBA: region 1 will have RGB 5%,5%,5%. region 2 will have RGB 10%,10%,10% and so on. HSV Greyscale: region 1 will have HSV 0,0,5%. region 2 will have HSV 0,0,10% and so on. (Values selected in The Gimp) The tex2D sampler returns a value [0..1]. [ I then intend to derive an int array index from region. Code to do with that is unrelated, so has been removed from the question ] float region = tex2D(gColourmapSampler,In.UV).x; Sampling the "5%" colour gave a "region" of 0.05098 in hlsl. From this I assume the 5% represents 5/100*255, or 12.75, which is rounded to 13 when stored in the texture OR when sampled by the sampler; can't tell which. (Reasoning: 0.05098 * 255 ~= 13) By this logic, the 50% should be stored as 127.5. Sampled, I get 0.50196 which implies it was stored as 128. the 70% should be stored as 178.5. Sampled, I get 0.698039, which implies it was stored as 178. What rounding is going on here? (127.5 becomes 128, 178.5 becomes 178 ?!) Edit: OK, http://en.wikipedia.org/wiki/Bankers_rounding#Round_half_to_even Apparently this is "banker's rounding". Is this really what HLSL samplers use? I am using Shader Model 2 and FX Composer. This is my sampler declaration; //Colour map texture gColourmapTexture < string ResourceName = "Globe_Colourmap_Regions_Greyscale.png"; string ResourceType = "2D"; >; sampler2D gColourmapSampler : register(s1) = sampler_state { Texture = <gColourmapTexture>; #if DIRECT3D_VERSION >= 0xa00 Filter = MIN_MAG_MIP_LINEAR; #else /* DIRECT3D_VERSION < 0xa00 */ MinFilter = Linear; MipFilter = Linear; MagFilter = Linear; #endif /* DIRECT3D_VERSION */ AddressU = Clamp; AddressV = Clamp; };

  • Cannot Call WordPress Plugin Files Under wp-content

    - by Volomike
    I have a client who has many blog customers. Each of these WordPress blogs calls a plugin that provides a product link. The way that link is composed looks like this: {website}/wp-content/plugins/prodx/product?id=432320 This works fine on all blogs except two. On those two, when you try to call the URL, you get a 404. So, I disabled all plugins except prodx and reverted the theme to default (Kubrick), thinking perhaps a plugin intercept with add_action() API was doing this, such as intercepting URLs and redirecting them. However, this did not help. So, I upgraded the WordPress to the latest version. Again, didn't fix. So, I checked permissions, comparing with a blog that worked just fine. Again, didn't fix. So I replaced the .htaccess, using one from a working blog. Again, didn't fix. So I replaced all the files using some from a working blog that was identical to this one, and then restored the wp-config.php file back so that it talked to the right blog database. Again, didn't fix. Again I checked permissions meticulously, comparing to a perfectly working blog. Again, didn't fix. So, I created a test.php that looks like so: <?php print_r($_GET); echo "hello world"; I then copied it into another plugin folder and used my browser to get to it -- again, 404. So I copied it into the root of wp-content/plugins and tried to call it there -- again, 404. So I copied it into wp-content -- again, 404. Last, I copied it into the root of the WordPress blog website, and this time, it worked! Doesn't make sense. I started to think that perhaps something was going on with /etc/httpd/conf/httpd.conf for this customer, but the only thing I saw different in their for this customer was the IP address was different than the customer's blog that worked. Each customer gets their own IP in this environment my client has built. My client sysop is baffled too. What do you think is going on? Is there something wrong in the WP database for this customer? Is there something wrong in httpd.conf?

The selected value from my combobox got saved into the DB then the page refreshed to display. When I went to edit page, to select another value, and clicked save button. On the display page, it's not saving. For example. on Create page I selected Regulatory. then I changed my mind and changed it to Mission Critical on Edit page. On display page it is not changed. I don't know what's wrong or what I'm missing here. Any help is welcome and truly appreciated. Thanks.

  • Copy all childNodes to an other element. In javascript native way.

    - by kroko
    Hello I have to change "unknown" contents of XML. The structure and content itself is valid. Original <blabla foo="bar"> <aa>asas</aa> <ff> <cc> <dd /> </cc> </ff> <gg attr2="2"> </gg> ... ... </blabla> becomes <blabla foo="bar"> <magic> <aa>asas</aa> <ff> <cc> <dd /> </cc> </ff> <gg attr2="2"> </gg> ... ... </magic> </blabla> thus, adding a child straight under document root node (document.documentElement) and "pushing" the "original" children under that. Here it has to be done in plain javascript (ecmascript). The idea now is to // Get the root node RootNode = mymagicdoc.documentElement; // Create new magic element (that will contain contents of original root node) var magicContainer = mymagicdoc.createElement("magic"); // Copy all root node children (and their sub tree - deep copy) to magic node /* ????? here RootNodeClone = RootNode.cloneNode(true); RootNodeClone.childNodes...... */ // Remove all children from root node while(RootNode.hasChildNodes()) RootNode.removeChild(RootNode.firstChild); // Now when root node is empty add the magicContainer // node in it that contains all the children of original root node RootNode.appendChild(magicContainer); How to do that /* */ step? Or maybe someone has a much better solution in general for achieving the desirable result? Thank you in advance!

  • How can I modify my classes to use it's collections in WPF TreeView

    - by Victor
    Hello, i'am trying to modify my objects to make hierarchical collection model. I need help. My objects are Good and GoodCategory: public class Good { int _ID; int _GoodCategory; string _GoodtName; public int ID { get { return _ID; } } public int GoodCategory { get { return _GoodCategory; } set { _GoodCategory = value; } } public string GoodName { get { return _GoodName; } set { _GoodName = value; } } public Good(IDataRecord record) { _ID = (int)record["ID"]; _GoodtCategory = (int)record["GoodCategory"]; } } public class GoodCategory { int _ID; string _CategoryName; public int ID { get { return _ID; } } public string CategoryName { get { return _CategoryName; } set { _CategoryName = value; } } public GoodCategory(IDataRecord record) { _ID = (int)record["ID"]; _CategoryName = (string)record["CategoryName"]; } } And I have two Collections of these objects: public class GoodsList : ObservableCollection<Good> { public GoodsList() { string goodQuery = @"SELECT `ID`, `ProductCategory`, `ProductName`, `ProductFullName` FROM `products`;"; using (MySqlConnection conn = ConnectToDatabase.OpenDatabase()) { if (conn != null) { MySqlCommand cmd = conn.CreateCommand(); cmd.CommandText = productQuery; MySqlDataReader rdr = cmd.ExecuteReader(); while (rdr.Read()) { Add(new Good(rdr)); } } } } } public class GoodCategoryList : ObservableCollection<GoodCategory> { public GoodCategoryList () { string goodQuery = @"SELECT `ID`, `CategoryName` FROM `product_categoryes`;"; using (MySqlConnection conn = ConnectToDatabase.OpenDatabase()) { if (conn != null) { MySqlCommand cmd = conn.CreateCommand(); cmd.CommandText = productQuery; MySqlDataReader rdr = cmd.ExecuteReader(); while (rdr.Read()) { Add(new GoodCategory(rdr)); } } } } } So I have two collections which takes data from the database. But I want to use thats collections in the WPF TreeView with HierarchicalDataTemplate. I saw many post's with examples of Hierarlichal Objects, but I steel don't know how to make my objects hierarchicaly. Please help.

  • How to get started with testing(jMock)

    - by London
    Hello, I'm trying to learn how to write tests. I'm also learning Java, I was told I should learn/use/practice jMock, I've found some articles online that help to certain extend like : http://www.theserverside.com/news/1365050/Using-JMock-in-Test-Driven-Development http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock And most articles I found was about test driven development, write tests first then write code to make the test pass. I'm not looking for that at the moment, I'm trying to write tests for already existing code with jMock. The official documentation is vague to say the least and just too hard for me. Does anybody have better way to learn this. Good books/links/tutorials would help me a lot. thank you EDIT - more concrete question : http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock - from this article Tried this to mock this simple class : import java.util.Map; public class Cache { private Map<Integer, String> underlyingStorage; public Cache(Map<Integer, String> underlyingStorage) { this.underlyingStorage = underlyingStorage; } public String get(int key) { return underlyingStorage.get(key); } public void add(int key, String value) { underlyingStorage.put(key, value); } public void remove(int key) { underlyingStorage.remove(key); } public int size() { return underlyingStorage.size(); } public void clear() { underlyingStorage.clear(); } } Here is how I tried to create a test/mock : public class CacheTest extends TestCase { private Mockery context; private Map mockMap; private Cache cache; @Override @Before public void setUp() { context = new Mockery() { { setImposteriser(ClassImposteriser.INSTANCE); } }; mockMap = context.mock(Map.class); cache = new Cache(mockMap); } public void testCache() { context.checking(new Expectations() {{ atLeast(1).of(mockMap).size(); will(returnValue(int.class)); }}); } } It passes the test and basically does nothing, what I wanted is to create a map and check its size, and you know work some variations try to get a grip on this. Understand better trough examples, what else could I test here or any other exercises would help me a lot. tnx

  • AJAX XML reply node value iteration

    - by XpiritO
    Hi there, guys. I would really appreciate to get your help on this, as I can't seem to detect and solve the problem I'm having with an AJAX functionality on a site that I'm currently developing. I have a webform that makes an asynchronous call to a handler (.ashx) that delivers a XML response that is later processed by a Javascript client-side function that places it's contents into the user-interface. I'm attaching an example of the response generated by my handler, and what I would like to know is how can I get all the <body> element innerHTML (with the text and child nodes) contents to append it to a <span> element on the user-interface. Can anyone help me out with this? XML Response returned by the handler (checked via Firebug): <message> <content> <messageId>2</messageId> <from>Barack Obama</from> <fromMail>[email protected]</fromMail> <subject>Yes, we can... get World Peace</subject> <body>Hello, dear citizen.

  • How can I implement ASP.NET MVC without using Visual Studio?

    - by Cheeso
    I have seen ASP.NET MVC Without Visual Studio, which asks, Is it possible to produce a website based on ASP.NET MVC, without using Visual Studio? And the accepted answer is, yes. Ok, next question: how? Here's an analogy. If I want to create an ASP.NET Webforms page, I load up my favorite text editor, create a file named Something.aspx. Then I insert into that file, some boilerplate: <%@ Page Language="C#" Debug="true" Trace="false" Src="Sourcefile.cs" Inherits="My.Namespace.ContentsPage" %> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Title goes here </title> <link rel="stylesheet" type="text/css" href="css/style.css"></link> <style type="text/css"> #elementid { font-size: 9pt; color: Navy; ... more css ... } </style> <script type="text/javascript" language='javascript'> // insert javascript here. </script> </head> <body> <asp:Literal Id='Holder' runat='server'/> <br/> <div id='msgs'></div> </body> </html> Then I also create the Sourcefile.cs file: namespace My.Namespace { using System; using System.Web; using System.Xml; // etc... public class ContentsPage : System.Web.UI.Page { protected System.Web.UI.WebControls.Literal Holder; void Page_Load(Object sender, EventArgs e) { // page load logic here } } } And that is a working ASPNET page, created in a text editor. Drop it into an IIS virtual directory, and it's working. What do I have to do, to make a basic, hello, World ASPNET MVC app, in a text editor? (without Visual Studio)

  • ASP.NET MVC : Good Replacement for User Control?

    - by David Lively
    I found user controls to be incredibly useful when working with ASP.NET webforms. By encapsulating the code required for displaying a control with the markup, creation of reusable components was very straightforward and very, very useful. While MVC provides convenient separation of concerns, this seems to break encapsulation (ie, you can add a control without adding or using its supporting code, leading to runtime errors). Having to modify a controller every time I add a control to a view seems to me to integrate concerns, not separate them. I'd rather break the purist MVC ideology than give up the benefits of reusable, packaged controls. I need to be able to include components similar to webforms user controls throughout a site, but not for the entire site, and not at a level that belongs in a master page. These components should have their own code not just markup (to interact with the business layer), and it would be great if the page controller didn't need to know about the control. Since MVC user controls don't have codebehind, I can't see a good way to do this. Update FINALLY, a good (and, in retrospect, obvious) way to accomplish this. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace K.ObjectModel.Controls { public class TestControl : ViewUserControl { protected override void Render(System.Web.UI.HtmlTextWriter writer) { writer.Write("Hello World"); base.Render(writer); } } } Create a new class which inherits ViewUserControl Override the .Render() method as shown above. Register the control via its associated ASCX as you would in a webForm: <%@ Register TagName="tn" TagPrefix="k" Src="~/Views/Navigation/LeftBar.ascx"%> Use the corresponding tag in whatever view or master page that you need: <k:tn runat="server"/> Make sure your .ascx inherits your new control: <%@ Control Language="C#" Inherits="K.ObjectModel.Controls.TestControl" %> Voila, you're up and running. This is tested with ASP.NET MVC 2, VS 2010 and .NET 4.0. Your custom tag references the ascx partial view, which inherits from the TestControl class. The control then overrides the Render() method, which is called to render the view, giving you complete control over the process from tag to output. Why does everyone try to make this so much harder than it has to be?

  • how to handle a array of objects in a session

    - by Robert
    Hello, In the project I'm working on I have got a list List<Item> with objects that Is saved in a session. Session.Add("SessionName", List); In the Controller I build a viewModel with the data from this session var arrayList = (List<Item>)Session["SessionName"]; var arrayListItems= new List<CartItem>(); foreach (var item in arrayList) { var listItem = new Item { Amount = item.Amount, Variant= item.variant, Id = item.Id }; arrayListItems.Add(listItem); } var viewModel = new DetailViewModel { itemList = arrayListItems } and in my View I loop trough the list of Items and make a form for all of them to be able to remove the item. <table> <%foreach (var Item in Model.itemList) { %> <% using (Html.BeginForm()) { %> <tr> <td><%=Html.Hidden(Settings.Prefix + ".VariantId", Item .Variant.Id)%> <td> <%=Html.TextBox(Settings.Prefix + ".Amount", Item.Amount)%></td> <td> <%=Html.Encode(Item.Amount)%> </td> <td> <input type="submit" value="Remove" /> </td> </tr> <% } %> <% } %> </table> When the post from the submit button is handeld the item is removed from the array and post back exactly the same viewModel (with 1 item less in the itemList). return View("view.ascx", viewModel); When the post is handled and the view has reloaded the value's of the html.Hidden and Html.Textbox are the value's of the removed item. The value of the html.Encode is the correct value. When i reload the page the correct values are in the fields. Both times i build the viewModel the exact same way.

  • How to develop a Jquery plugin to find the first child that match with a selector?

    - by Ivan
    I'm trying to make a Jquery plugin (findFirst()) to find the first child with a given characteristics (something in the middle of the find() and children() functions. For instance, given this markup: <div id="start"> <div> <span>Hello world</span> <ul class="valid-result"> ... </ul> <ul class="valid-result"> <li> <ul class="not-a-result"> ... </ul> </li> </ul> <div> <ul class="valid-result"> ... </ul> </div> </div> </div> If you ask for $("#start").findFirst('ul') it should return all ul lists that I have tagged with the valid-result class, but not the ul with class not-a-result. It is, this function has to find the first elements that matches with a given selector, but not the inner elements that match this selector. This is the first time I try to code a Jquery function, and what I've already read doesn't helps me too much with this. The function I have developed is this: jQuery.fn.findFirst = function (sel) { return this.map(function() { return $(this).children().map(function() { if ($(this).is(sel)) { return $(this); } else { return $(this).findFirst(sel); } }); }); } It works in the sense it tries to return the expected result, but the format it returns the result is very rare for me. I suppose the problem is something I don't understand about Jquery. Here you have the JFiddle where I'm testing. EDIT The expected result after $("#start").findFirst('ul') is a set with all UL that have the class 'valid-result' BUT it's not possible to use this class because it doesn't exist in a real case (it's just to try to explain the result). This is not equivalent to first(), because first returns only one element!
