• Web Self Service installation on Windows

  - by Rajesh Sharma

  Web Self Service (WSS) installation on windows is pretty straight forward but you might face some issues if deployed under tomcat. Here's a step-by-step guide to install Oracle Utilities Web Self Service on windows.   Below installation steps are done on: Oracle Utilities Framework version 2.2.0 Oracle Utilities Application - Customer Care & Billing version 2.2.0 Application server - Apache Tomcat 6.0.13 on default port 6500 Other settings include: SPLBASE = C:\spl\CCBDEMO22 SPLENVIRON = CCBV22 SPLWAS = TCAT   Follow these steps for a Web Self Service installation on windows: Download Web Self Service application from edelivery.   Copy the delivery file Release-SelfService-V2.2.0.zip from the Oracle Utilities Customer Care and Billing version 2.2.0 Web Self Service folder on the installation media to a directory on your Windows box where you would like to install the application, in our case it's a temporary folder C:\wss_temp.   Setup application environment, execute splenviron.cmd -e <ENVIRON_NAME>   Create base folder for Self Service application named SelfService under %SPLEBASE%\splapp\applications   Install Oracle Utilities Web Self Service   C:\wss_temp\Release-SelfService-V2.2.0>install.cmd -d %SPLEBASE%\splapp\applications\SelfService   Web Self Service installation menu. Populate environment values for each item.   ******************************************************** Pick your installation options: ******************************************************** 1. Destination directory name for installation.             | C:\spl\CCBDEMO22\splapp\applications\SelfService 2. Web Server Host.                                         | CCBV22 3. Web Server Port Number.                                  | 6500 4. Mail SMTP Host.                                          | CCBV22 5. Top Product Installation directory.                      | C:\spl\CCBDEMO22 6.     Web Application Server Type.                         | TCAT 7.     When OAS: SPLWeb OC4J instance name is required.     | OC4J1 8.     When WAS: SPLWeb server instance name is required.   | server1   P. Process the installation. Each item in the above list should be configured for a successful installation. Choose option to configure or (P) to process the installation:  P   Option 7 and Option 8 can be ignored for TCAT.   Above step installs SelfService.war file in the destination directory. We need to explode this war file. Change directory to the installation destination folder, and   C:\spl\CCBDEMO22\splapp\applications\SelfService>jar -xf SelfService.war   Review SelfServiceConfig.properties and CMSelfServiceConfig.properties. Change any properties value within the file specific to your installation/site. Generally default settings apply, for this exercise assumes that WEB user already exists in your application database.   For more information on property file customization, refer to Oracle Utilities Web Self Service Configuration section in Customer Care & Billing Installation Guide.   Add context entry in server.xml located under tomcat-base folder C:\spl\CCBDEMO22\product\tomcatBase\conf   ... <!-- SPL Context -->           <Context path="" docBase="C:/spl/CCBDEMO22/splapp/applications/root" debug="0" privileged="true"/>           <Context path="/appViewer" docBase="C:/spl/CCBDEMO22/splapp/applications/appViewer" debug="0" privileged="true"/>           <Context path="/help" docBase="C:/spl/CCBDEMO22/splapp/applications/help" debug="0" privileged="true"/>           <Context path="/XAIApp" docBase="C:/spl/CCBDEMO22/splapp/applications/XAIApp" debug="0" privileged="true"/>           <Context path="/SelfService" docBase="C:/spl/CCBDEMO22/splapp/applications/SelfService" debug="0" privileged="true"/> ...   Add User in tomcat-users.xml file located under tomcat-base folder C:\spl\CCBDEMO22\product\tomcatBase\conf   <user username="WEB" password="selfservice" roles="cisusers"/>   Note the password is "selfservice", this is the default password set within the SelfServiceConfig.properties file with base64 encoding.   Restart the application (spl.cmd stop | start)   12.  Although Apache Tomcat version 6.0.13 does not come with the admin pack, you can verify whether SelfService application is loaded and running, go to following URL http://server:port/manager/list, in our case it'll be http://ccbv22:6500/manager/list Following output will be displayed   OK - Listed applications for virtual host localhost /admin:running:0:C:/tomcat/apache-tomcat-6.0.13/webapps/ROOT/admin /XAIApp:running:0:C:/spl/CCBDEMO22/splapp/applications/XAIApp /host-manager:running:0:C:/tomcat/apache-tomcat-6.0.13/webapps/host-manager /SelfService:running:0:C:/spl/CCBDEMO22/splapp/applications/SelfService /appViewer:running:0:C:/spl/CCBDEMO22/splapp/applications/appViewer /manager:running:1:C:/tomcat/apache-tomcat-6.0.13/webapps/manager /help:running:0:C:/spl/CCBDEMO22/splapp/applications/help /:running:0:C:/spl/CCBDEMO22/splapp/applications/root   Also ensure that the XAIApp is running.   Run Oracle Utilities Web Self Service application http://server:port/SelfService in our case it'll be  http://ccbv22:6500/SelfService   Still doesn't work? And you get '503 HTTP response' at the time of customer registration?     This is because XAI service is still unavailable. There is initialize.waittime set for a default value of 90 seconds for the XAI Application to come up.   Remember WSS uses XAI to perform actions/validations on the CC&B database.

• How to programatically self delete? (C# WinMobile)

  - by Christian Almeida

  How to programatically self delete? C# / .NetCF2 / Windows Mobile 6 Please, I don't want to discuss WHY to do it, I just need to know HOW to do it! Important: The "second application" approach is NOT an option. (Unless that second application can be "extracted" from running app, but I don't know how to do it!). No problem in forced reboot, if windows do the trick at startup. (Is it possible? Nice! Show me how!). Code samples are welcome.

• Entity Frameworks 4 - Changing the model does not update the T4 self tracking template files

  - by Darren

  I am using self tracking entities and have moved the entity classes to another assembly by using 'Add as link' to point to the TT file as mentioned here. Now though, when I update the model (for instance change a property name) the template is not automatically run and so the entity class does not get updated. I can of course manually run the template to get the updates, but it would be easier if it ran automatically in the way it did before I moved the classes. Is there any way to achieve this? Darren.

• Metaprograming - self explanatory code - tutorials, articles, books

  - by elena

  Hello everybody, I am looking into improving my programming skils (actually I try to do my best to suck less each year, as our Jeff Atwood put it), so I was thinking into reading stuff about metaprogramming and self explanatory code. I am looking for something like an idiot's guide to this (free books for download, online resources). Also I want more than your average wiki page and also something language agnostic or preferably with Java examples. Do you know of such resources that will allow to efficiently put all of it into prectice (I know experience has a lot to say in all of this but i kind of want to build experience avoiding the flow bad decitions - experience - good decitions)? Thank you!

• Scalable way of doing self join with many to many table

  - by johnathan

  I have a table structure like the following: user id name profile_stat id name profile_stat_value id name user_profile user_id profile_stat_id profile_stat_value_id My question is: How do I evaluate a query where I want to find all users with profile_stat_id and profile_stat_value_id for many stats? I've tried doing an inner self join, but that quickly gets crazy when searching for many stats. I've also tried doing a count on the actual user_profile table, and that's much better, but still slow. Is there some magic I'm missing? I have about 10 million rows in the user_profile table and want the query to take no longer than a few seconds. Is that possible?

• Self Modifying Code

  - by Betamoo

  I am recently thinking about writing self-modifying programs, I think it may be powerful and fun... So I am currently looking for a language that allow modifying program own code easily.. I read about C# and the ability to compile -and execute- code in runtime, but that is too hurting.. I am also thinking about assembly... it is easier there to change running code but it is not very powerful... Can you suggest me a powerful language -or a feature- that support modifying code in runtime..? Hint: That what I mean by modifying code in runtime Start: a=10,b=20,c=0 label1: c=a+b .... label1= c=a*b goto label1 Thanks

• Jquery html() and self closing tags

  - by Pedro Reis

  While creating self contained elements with Jquery html() the following issue happens: $('#someId').html('<li><input type="checkbox" /></li>') will create <li><input type="checkbox"></li> It closes correctly the <li> tag but not the <input> It seems its an issue from innerHtml which is used in the html() function. I have looked everywhere and found a solution for this but the page is not available anymore as you see in: http://dev.jquery.it/ticket/3378 Anybody knows how to fix this?

• SQL Server 2008 Delete Records from Self-Referencing Table in correct order

  - by KTrace

  I need to delete a sub set of records from a self-referencing table in SQL Server 2008. I am trying to do the following but it is does not like the order by. WITH SelfReferencingTable (ID, depth) AS ( SELECT id, 0 as [depth] FROM dbo.Table WHERE parentItemID IS NULL AND [t].ColumnA = '123' UNION ALL SELECT [t].ID, [srt].[depth] + 1 FROM dbo.Table t INNER JOIN SelfReferencingTable srt ON [t].parentItemID = [srt].id WHERE [t].ColumnA = '123' ) DELETE y FROM dbo.Table y JOIN SelfReferencingTable x on x.ID = y.id ORDER BY x.depth DESC Any ideas why this isn't working?

• rails: self-referential association

  - by john

  hi, My needs are very simple: I have a Tip table to receive comments and have comments to receive comments, too. To retrieve each comment that is stored in the same table (comments), I created another key for the comments on comments: "inverse_comments". I tried to use one comments table by using self-referntial association. Some resources seem to bring more than one table into the piture which are diffent from my needs. So I came up whth the following modeling for comments: class Comment < ActiveRecord::Base belongs_to :tip belongs_to :user has_many :mycomments, :through => :inverse_comments, :source => :comment end Apparently something is missing here but I cannot figure it out. Could some one enlighten me on this: what changes I need to do to make the model work? thanks.

• Using two joysticks in Cocos2D

  - by Blade

  Here is what I am trying to do: With the left joystick the player can steer the figure and with the right joystick it can attack. Problem is that the left joystick seems to get all the input, the right one does not even register anything. I enabled multipletouch after the eagleView and gone thoroughly over the code. But I seem to miss something. I initiliaze both sticks and it shows me both of them in game, but like I said, only the left one works. I initialize them both. From the h. file: SneakyJoystick *joystick; SneakyJoystick *joystickRight; And in m.file I synthesize, deallocate and initialize them. In order to use one for controlling and the other for attacking I put this: -(void)updateStateWithDeltaTime:(ccTime)deltaTime andListOfGameObjects:(CCArray*)listOfGameObjects { if ((self.characterState == kStateIdle) || (self.characterState == kStateWalkingBack) || (self.characterState == kStateWalkingLeft) || (self.characterState == kStateWalkingRight)|| (self.characterState == kStateWalkingFront) || (self.characterState == kStateAttackingFront) || (self.characterState == kStateAttackingBack)|| (self.characterState == kStateAttackingRight)|| (self.characterState == kStateAttackingLeft)) { if (joystick.degrees > 60 && joystick.degrees < 120) { if (self.characterState != kStateWalkingBack) [self changeState:kStateWalkingBack]; }else if (joystick.degrees > 1 && joystick.degrees < 59) { if (self.characterState != kStateWalkingRight) [self changeState:kStateWalkingRight]; } else if (joystick.degrees > 211 && joystick.degrees < 300) { if (self.characterState != kStateWalkingFront) [self changeState:kStateWalkingFront]; } else if (joystick.degrees > 301 && joystick.degrees < 360){ if (self.characterState != kStateWalkingRight) [self changeState:kStateWalkingRight]; } else if (joystick.degrees > 121 && joystick.degrees < 210) { if (self.characterState != kStateWalkingLeft) [self changeState:kStateWalkingLeft]; } if (joystickRight.degrees > 60 && joystickRight.degrees < 120) { if (self.characterState != kStateAttackingBack) [self changeState:kStateAttackingBack]; }else if (joystickRight.degrees > 1 && joystickRight.degrees < 59) { if (self.characterState != kStateAttackingRight) [self changeState:kStateAttackingRight]; } else if (joystickRight.degrees > 211 && joystickRight.degrees < 300) { if (self.characterState != kStateAttackingFront) [self changeState:kStateAttackingFront]; } else if (joystickRight.degrees > 301 && joystickRight.degrees < 360){ if (self.characterState != kStateAttackingRight) [self changeState:kStateAttackingRight]; } else if (joystickRight.degrees > 121 && joystickRight.degrees < 210) { if (self.characterState != kStateAttackingLeft) [self changeState:kStateAttackingLeft]; } [self applyJoystick:joystick forTimeDelta:deltaTime]; [self applyJoystick:joystickRight forTimeDelta:deltaTime]; } Maybe it has something to do with putting them both to time delta? I tried working around it, but it did not work. So I am thankful for any input you guys can give me :)

• When is the best time to do self learning in relation with software management?

  - by shankbond

  It all started from here. I have been following Software Estimation: Demystifying the Black Art (Best Practices (Microsoft)). The third chapter says that in Software Management: You cannot give too much time to software developers, if you give it to them, then it is likely that extra time given to them will be filled by some other tasks (in other words, the developers will eat that time :)) Parkinson's Law You can also not squeeze the time from their schedule because if you do that, it is likely that they will develop poor quality product, poor design and will hurt you in the long run, there will be a panic situation and total chaos in the project, lots of rework etc. My question is related to the first point. If you don't give enough time then will the typical software engineer learn his/her skills? The market is always coming with new technologies, you need to learn them. Even with the existing familiar technologies there are always best practices and dos and don'ts.

• How important is self-teaching in the programming field? [closed]

  - by ThePlan

  I'm 16. I started programming about a year ago when I was about to start high-school. I'm going for a career in programming, and I'm doing my best to learn as much as I can. When I first started, I learned the basics of C++ from a book and I started to learn things by myself from there on. Nowadays I'm much more experienced than I was a year ago. I knew I had to study by myself because high-school won't (likely) teach me anything valuable about programming, and I want to be prepared. The question here is: how important is it to study programming by oneself?

• "Learning" Linux

  - by Strider

  I've been interested in computers for a long time and have fiddled with a lot of stuff which includes Linux. I started out with Red Hat when I was young (around 13) and lost all data, converting a FAT32 drive to something else. Later it was Knoppix which was really helpful in recovery and such. Then, it was Ubuntu. Also, I fiddled with Arch for some time, but, it breaks too often for my liking (maybe, I should have been more careful). Anyway, currently I use Ubuntu 9.04. I want to dig deeper into the Linux world now. I want to learn how things work and use the terminal more. I am a programmer as well, so, it will help a lot. So, the thing I wanted to ask were: Good books to learn and understand Linux Good habits to use Linux more efficiently. Good tools about which I should know. Amount of time you set aside to learn about new things each day. As a programmer, how do you setup and use Linux efficiently. Long list. I will be grateful to the answerers.

• Self hosted WCF ServiceHost/WebServiceHost Concurrency/Peformance Design Options (.NET 3.5)

  - by Kyle

  So I'll be providing a few functions via a self hosted (in a WindowsService) WebServiceHost (not sure how to process HTTP GET/POST with ServiceHost), one of which may be called a large amount of the time. This function will also rely on a connection in the appdomain (hosted by the WindowsService so it can stay alive over multiple requests). I have the following concerns and would be oh so thankful for any input/thoughts/comments: Concurrent access - how does the WebServiceHost handle a bunch of concurrent requests. Are they queued and processes sequentially or are new instances of the contracts automagically created? WebServiceHost - WindowsService communication - I need some form of communication from the WebServiceHost to the hosting WindowsService for things like requesting a new session if one does not exist. Perhaps implementing a class which extends the WebServiceHost with events which the WindowsService subscribes to... (unless there is another way I can set off an event in the WindowsService when a request is made...) Multiple WebServiceHosts or Contracts - Would it give any real performance gain to be running multiple WebServiceHost instances in different threads (one per endpoint perhaps?) - A better understanding of the first point would probably help here. WSDL - I'm not sure why (probably just need to do more reading), but I'm not sure how to get the WebServiceHost base endpoint to respond with a WDSL document describing the available contract. Not required as all the operations will be done via GET requests which will not likely change, but it would be nice to have... That's about it for the moment ;) I've been reading a lot on WCF and wish I'd gotten into it long ago, but definitely still learning.

Some commands are followed by a single number. For example, the following input would draw a rectangle: P 2 # select pen 2 D # pen down W 2 # draw west 2cm N 1 # then north 1 E 2 # then east 2 S 1 # then back south U # pen up Thank you!

• SQLite self-join performance

  - by Derk

  What I essentially want, is to retreive all features and values of products which have a particular feature and value. For example: I want to know all available hard drive sizes of products that have an Intel processor. I have three tables: product_to_value (product_id, feature_id, value_id) features (id, value) // for example Processor family, Storage size, etc. values (id, value) // for example Intel, 60GB, etc The simplified query I have now: SELECT features.name, featurevalues.name, featurevalues.value FROM products, products as prod2, features, features as feat2, values, values as val2 WHERE products.feature = features.id AND products.value = values.id AND products.product = prod2.product AND prod2.feature_id = feat2.id AND prod2.value_id = val2.id AND features.id = ? AND feat2.id = ? All columns have an index. I am using SQLite. The problem is that it's very slow (70ms per query, without the self-join it's <1ms). Is there a smarter way to fetch data like this? Or is this too much to ask from SQLite? I personally think I am simply overlooking something, as I am quite new to SQLite.

• wxPthon problems with Wrapping StaticText

  - by Scott B

  Hello. I am having an issue with wxPython. A simplified version of the code is posted below (white space, comments, etc removed to reduce size - but the general format to my program is kept roughly the same). When I run the script, the static text correctly wraps as it should, but the other items in the panel do not move down (they act as if the statictext is only one line and thus not everything is visible). If I manually resize the window/frame, even just a tiny amount, everything gets corrected and displays as it is should. I took screen shots to show this behavior, but I just created this account and thus don't have the required 10 reputation points to be allowed to post pictures. Why does it not display correctly to begin with? I've tried all sorts of combination's of GetParent().Refresh() or Update() and GetTopLevelParent().Update() or Refresh(). I've tried everything I can think of but cannot get it to display correctly without manually resizing the frame/window. Once re-sized, it works exactly as I want it to. Information: Windows XP Python 2.5.2 wxPython 2.8.11.0 (msw-unicode) Any suggestions? Thanks! Code: #! /usr/bin/python import wx class StaticWrapText(wx.PyControl): def __init__(self, parent, id=wx.ID_ANY, label='', pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.NO_BORDER, validator=wx.DefaultValidator, name='StaticWrapText'): wx.PyControl.__init__(self, parent, id, pos, size, style, validator, name) self.statictext = wx.StaticText(self, wx.ID_ANY, label, style=style) self.wraplabel = label #self.wrap() def wrap(self): self.Freeze() self.statictext.SetLabel(self.wraplabel) self.statictext.Wrap(self.GetSize().width) self.Thaw() def DoGetBestSize(self): self.wrap() #print self.statictext.GetSize() self.SetSize(self.statictext.GetSize()) return self.GetSize() class TestPanel(wx.Panel): def __init__(self, *args, **kwargs): # Init the base class wx.Panel.__init__(self, *args, **kwargs) self.createControls() def createControls(self): # --- Panel2 ------------------------------------------------------------- self.Panel2 = wx.Panel(self, -1) msg1 = 'Below is a List of Files to be Processed' staticBox = wx.StaticBox(self.Panel2, label=msg1) Panel2_box1_v1 = wx.StaticBoxSizer(staticBox, wx.VERTICAL) Panel2_box2_h1 = wx.BoxSizer(wx.HORIZONTAL) Panel2_box3_v1 = wx.BoxSizer(wx.VERTICAL) self.wxL_Inputs = wx.ListBox(self.Panel2, wx.ID_ANY, style=wx.LB_EXTENDED) sz = dict(size=(120,-1)) wxB_AddFile = wx.Button(self.Panel2, label='Add File', **sz) wxB_DeleteFile = wx.Button(self.Panel2, label='Delete Selected', **sz) wxB_ClearFiles = wx.Button(self.Panel2, label='Clear All', **sz) Panel2_box3_v1.Add(wxB_AddFile, 0, wx.TOP, 0) Panel2_box3_v1.Add(wxB_DeleteFile, 0, wx.TOP, 0) Panel2_box3_v1.Add(wxB_ClearFiles, 0, wx.TOP, 0) Panel2_box2_h1.Add(self.wxL_Inputs, 1, wx.ALL|wx.EXPAND, 2) Panel2_box2_h1.Add(Panel2_box3_v1, 0, wx.ALL|wx.EXPAND, 2) msg = 'This is a long line of text used to test the autowrapping ' msg += 'static text message.

  I have an Entity containing Self-Referenced mapping. class Category { /** * @var integer * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @var string * * @ORM\Column(name="name", type="string", length=100) */ private $name; /** * @ORM\OneToMany(targetEntity="Category", mappedBy="parent") */ private $children; /** * @ORM\ManyToOne(targetEntity="Category", inversedBy="children") * @ORM\JoinColumn(name="parent_id", referencedColumnName="id") */ private $parent; } In my CategoryType I have this : public function buildForm(FormBuilderInterface $builder, array $options) { $plan = $this->plan; $builder->add('name'); $builder->add('parent', 'entity', array( 'class' => 'xxxBundle:Category', 'property' => 'name', 'empty_value' => 'Choose a parent category', 'required' => false, 'query_builder' => function(EntityRepository $er) use ($plan) { return $er->createQueryBuilder('u') ->where('u.plan = :plan') ->setParameter('plan', $plan) ->orderBy('u.id', 'ASC'); }, )); } Actually, when I render the form field Category this is something like Cat1 Cat2 Cat3 Subcat1 Subcat2 Cat4 I would like to know if it's possible and how to display something more like, a kind of a simple tree representation : Cat1 Cat2 Cat3 -- Subcat1 -- Subcat2 Cat4 Regards.

• PyQt application architecture

  - by L. De Leo

  I'm trying to give a sound structure to a PyQt application that implements a card game. So far I have the following classes: Ui_Game: this describes the ui of course and is responsible of reacting to the events emitted by my CardWidget instances MainController: this is responsible for managing the whole application: setup and all the subsequent states of the application (like starting a new hand, displaying the notification of state changes on the ui or ending the game) GameEngine: this is a set of classes that implement the whole game logic Now, the way I concretely coded this in Python is the following: class CardWidget(QtGui.QLabel): def __init__(self, filename, *args, **kwargs): QtGui.QLabel.__init__(self, *args, **kwargs) self.setPixmap(QtGui.QPixmap(':/res/res/' + filename)) def mouseReleaseEvent(self, ev): self.emit(QtCore.SIGNAL('card_clicked'), self) class Ui_Game(QtGui.QWidget): def __init__(self, window, *args, **kwargs): QtGui.QWidget.__init__(self, *args, **kwargs) self.setupUi(window) self.controller = None def place_card(self, card): cards_on_table = self.played_cards.count() + 1 print cards_on_table if cards_on_table <= 2: self.played_cards.addWidget(card) if cards_on_table == 2: self.controller.play_hand() class MainController(object): def __init__(self): self.app = QtGui.QApplication(sys.argv) self.window = QtGui.QMainWindow() self.ui = Ui_Game(self.window) self.ui.controller = self self.game_setup() Is there a better way other than injecting the controller into the Ui_Game class in the Ui_Game.controller? Or am I totally off-road?

• WCF Self Host Service - Endpoints in C#

  - by Kyle

  My first few attempts at creating a self hosted service. Trying to make something up which will accept a query string and return some text but have have a few issues: All the documentation talks about endpoints being created automatically for each base address if they are not found in a config file. This doesn't seem to be the case for me, I get the "Service has zero application endpoints..." exception. Manually specifying a base endpoint as below seems to resolve this: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; using System.ServiceModel.Description; namespace TestService { [ServiceContract] public interface IHelloWorldService { [OperationContract] string SayHello(string name); } public class HelloWorldService : IHelloWorldService { public string SayHello(string name) { return string.Format("Hello, {0}", name); } } class Program { static void Main(string[] args) { string baseaddr = "http://localhost:8080/HelloWorldService/"; Uri baseAddress = new Uri(baseaddr); // Create the ServiceHost. using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress)) { // Enable metadata publishing. ServiceMetadataBehavior smb = new ServiceMetadataBehavior(); smb.HttpGetEnabled = true; smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15; host.Description.Behaviors.Add(smb); host.AddServiceEndpoint(typeof(IHelloWorldService), new BasicHttpBinding(), baseaddr + "SayHello"); //for some reason a default endpoint does not get created here host.Open(); Console.WriteLine("The service is ready at {0}", baseAddress); Console.WriteLine("Press to stop the service."); Console.ReadLine(); // Close the ServiceHost. host.Close(); } } } } I still think I'm doing something wrong as I don't get the normal "This is a web service...etc..." page when I load up the url How would I go about setting this up to return the value of name in SayHello(string name) when requested thusly: localhost:8080/HelloWorldService/SayHello?name=kyle Do I have to create an endpoing for the SayHello contract as well? I'm trying to walk before running, but this just seems like crawling...Service has zero application endpoints...

• Multiple Context menus in PyQt based on mouse location

  - by Nader

  I have a window with multiple tables using QTableWidget (PyQt). I created a popup menu using the right click mouse and it works fine. However, I need to create different popup menu based on which table the mouse is hovering over at the time the right mouse is clicked. How can I get the mouse to tell me which table it is hovering over? or, put in another way, how to implement a method so as to have a specific context menu based on mouse location? I am using Python and PyQt. My popup menu is developed similar to this code (PedroMorgan answer from Qt and context menu): class Foo( QtGui.QWidget ): def __init__(self): QtGui.QWidget.__init__(self, None) # Toolbar toolbar = QtGui.QToolBar() # Actions self.actionAdd = toolbar.addAction("New", self.on_action_add) self.actionEdit = toolbar.addAction("Edit", self.on_action_edit) self.actionDelete = toolbar.addAction("Delete", self.on_action_delete) # Tree self.tree = QtGui.QTreeView() self.tree.setContextMenuPolicy( Qt.CustomContextMenu ) self.connect(self.tree, QtCore.SIGNAL('customContextMenuRequested(const QPoint&)'), self.on_context_menu) # Popup Menu self.popMenu = QtGui.QMenu( self ) self.popMenu.addAction( self.actionEdit ) self.popMenu.addAction( self.actionDelete ) self.popMenu.addSeparator() self.popMenu.addAction( self.actionAdd ) def on_context_menu(self, point): self.popMenu.exec_( self.tree.mapToGlobal(point) )

• [Tkinter/Python] Different line widths with canvas.create_line?

  - by Sam

  Does anyone have any idea why I get different line widths on the canvas in the following example? from Tkinter import * bigBoxSize = 150 class cFrame(Frame): def __init__(self, master, cwidth=450, cheight=450): Frame.__init__(self, master, relief=RAISED, height=550, width=600, bg = "grey") self.canvasWidth = cwidth self.canvasHeight = cheight self.canvas = Canvas(self, bg="white", width=cwidth, height=cheight, border =0) self.drawGridLines() self.canvas.pack(side=TOP, pady=20, padx=20) def drawGridLines(self, linewidth = 10): self.canvas.create_line(0, 0, self.canvasWidth, 0, width= linewidth ) self.canvas.create_line(0, 0, 0, self.canvasHeight, width= linewidth ) self.canvas.create_line(0, self.canvasHeight, self.canvasWidth + 2, self.canvasHeight, width= linewidth ) self.canvas.create_line(self.canvasWidth, self.canvasHeight, self.canvasWidth, 1, width= linewidth ) self.canvas.create_line(0, bigBoxSize, self.canvasWidth, bigBoxSize, width= linewidth ) self.canvas.create_line(0, bigBoxSize * 2, self.canvasWidth, bigBoxSize * 2, width= linewidth) root = Tk() C = cFrame(root) C.pack() root.mainloop() It's really frustrating me as I have no idea what's happening. If anyone can help me out then that'd be fantastic. Thanks!

• Python: Why Does a Method Behave Differently with an Added Parameter?

  - by SteveStifler

  I have a method in a Pygame Sprite subclass, defined as such: def walk(self): """move across screen""" displacement = self.rect.move((self.move, 0)) if self.rect.left < self.area.left or self.rect.right > self.area.right: self.move = -self.move displacement = self.rect.move((self.move, 0)) self.rect = displacement I modified it, adding a parameter speed_x, and now the program is broken. def walk(self, speed_x): """move across screen""" displacement = self.rect.move((speed_x, 0)) if self.rect.left < self.area.left or self.rect.right > self.area.right: speed_x = -speed_x displacement = self.rect.move((speed_x, 0)) self.rect = displacement Before I called the method like this: def update(self): self.walk() Now I do: def update(self): self.walk(self.move) Why doesn't this work?

• Hibernate3: Self-Referencing Objects

  - by monojohnny

  Need some help on understanding how to do this; I'm going to be running recursive 'find' on a file system and I want to keep the information in a single DB table - with a self-referencing hierarchial structure: This is my DB Table structure I want to populate. DirObject Table: id int NOT NULL, name varchar(255) NOT NULL, parentid int NOT NULL); Here is the proposed Java Class I want to map (Fields only shown): public DirObject { int id; String name; DirObject parent; ... For the 'root' directory was going to use parentid=0; real ids will start at 1, and ideally I want hibernate to autogenerate the ids. Can somebody provide a suggested mapping file for this please; as a secondary question I thought about doing the Java Class like this instead: public DirObject { int id; String name; List<DirObject> subdirs; Could I use the same data model for either of these two methods ? (With a different mapping file of course). --- UPDATE: so I tried the mapping file suggested below (thanks!), repeated here for reference: <hibernate-mapping> <class name="my.proj.DirObject" table="category"> ... <set name="subDirs" lazy="true" inverse="true"> <key column="parentId"/> <one-to-many class="my.proj.DirObject"/> </set> <many-to-one name="parent" class="my.proj.DirObject" column="parentId" cascade="all" /> </class> ...and altered my Java class to have BOTH 'parentid' and 'getSubDirs' [returning a 'HashSet']. This appears to work - thanks, but this is the test code I used to drive this - I think I'm not doing something right here, because I thought Hibernate would take care of saving the subordinate objects in the Set without me having to do this explicitly ? DirObject dirobject=new DirObject(); dirobject.setName("/files"); dirobject.setParent(dirobject); DirObject d1, d2; d1=new DirObject(); d1.setName("subdir1"); d1.setParent(dirobject); d2=new DirObject(); d2.setName("subdir2"); d2.setParent(dirobject); HashSet<DirObject> subdirs=new HashSet<DirObject>(); subdirs.add(d1); subdirs.add(d2); dirobject.setSubdirs(subdirs); session.save(dirobject); session.save(d1); session.save(d2);
