• What is the point of JComboBox's getSelectedItem()?

  - by Chris Cooper

  I just read the JavaDoc for JComboBox (I promise I have a life... I wasn't reading through for fun. =P), and I think the problems I'm having with my program can be attributed to the getSelectedItem() method. The documentation says: Returns the current selected item. If the combo box is editable, then this value may not have been added to the combo box with addItem, insertItemAt or the data constructors. If you can't get values that were added with those methods or with the constructor, of what use is the method? And how can I get the value from an "editable" JComboBox? Link to JavaDoc: http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JComboBox.html#getSelectedItem()

• Are there any PHP DocBlock parser tools available?

  - by Beau Simensen

  I would like to build some smaller scale but hightly customized documentation sites for a few projects. PhpDocumentor is pretty great but it is very heavy. I thought about trying to tweak the templates for that but after spending only a couple of minutes looking into it I decided that it would be too much work. Ideally I'd like to see something to which I could pass a bunch of files and have it return all of the files, classes and properties and methods, along with their meta data, so that I could build out some simple templates based on the data. Are there any DocBlock parser-only projects that will help me in this task, or am I stuck reinventing that wheel?

• asp.net InsertCommand to return latest insert ID

  - by Stijn Van Loo

  Dear all, I'm unable to retrieve the latest inserted id from my SQL Server 2000 db using a typed dataset in asp.NET I have created a tableadapter and I ticked the "Refresh datatable" and "Generate Insert, Update and Delete statements". This auto-generates the Fill and GetData methods, and the Insert, Update, Select and Delete statements. I have tried every possible solution in this thread http://forums.asp.net/t/990365.aspx but I'm still unsuccesfull, it always returns 1(=number of affected rows). I do not want to create a seperate insert method as the auto-generated insertCommand perfectly suits my needs. As suggested in the thread above, I have tried to update the InsertCommand SQL syntax to add SELECT SCOPY_IDENTITY() or something similar, I have tried to add a parameter of type ReturnValue, but all I get is the number of affected rows. Does anyone has a different take on this? Thanks in advance! Stijn

• Ruby Net::HTTP - Read only x number of bytes of the body

  - by bvanderw

  It seems like the methods of Ruby's Net::HTTP are all or nothing when it comes to reading the body of a web page. How can I read, say, the just the first 100 bytes of the body? I am trying to read from a content server that returns a short error message in the body of the response if the file requested isn't available. I need to read enough of the body to determine whether the file is there. The files are huge, so I don't want to get the whole body just to check if the file is available.

• Passing Custom headers from .Net 1.1 client to a WCF service

  - by sreejith

  I have a simple wcf service which uses basicHttp binding, I want to pass few information from client to this service via custom SOAP header. My client is a .net application targetting .Net 1.1, using visual studio I have created the proxy( Added a new web reference pointing to my WCF service) I am able to call methods in the WCF service but not able to pass the data in message header. Tried to override "GetWebRequest" and added custom headers in the proxy but for some reason when I tried to access the header using "OperationContext.Current.IncomingMessageHeaders.FindHeader" it is not thier. Any idea how to solve this prob? This is how I added the headers protected override System.Net.WebRequest GetWebRequest(Uri uri) { HttpWebRequest request; request = (HttpWebRequest)base.GetWebRequest(uri); request.Headers.Add("tesData", "test"); return request; }

I just google around for some solution and i found wsimport and wsdl2java(Axis) are two options in java domain. But i am still unable to find any solution related to Android. Can anyone suggest me the best practice in such scenario?

• updating dojo grid cell values in the server

  - by Raj

  I am using dojo datagrid to display my data. When the end user edit the cell values it should be updated in the server using ajax calls(when the focus goes out of the cell). Else, I should have a Edit & update/cancel buttons for each row to handle the same feature. But I don know how to place edit & update buttons inside the grid and capture their events. By default dojo updates only local the store value(client side). how can I save the updated cell values into the server? do we need to write any override methods to do so?? I am new to dojo. Any detailed explanation or sample codes would be much appreciated. Could anyone lend a hand to solve this issue?? Thank you Regards, Raj

• Calculating string sizes on iPhone on a background thread

  - by jbrennan

  I've got some somewhat hefty string size calculations happening in my app (each one takes close to 500ms, and happens when the user scrolls to a new "page" in my app (like the Weather app). The delay only happens once per page, as the calculation only needs to be run once (and can even be cached for subsequent launches with the same data). Anyway, I still like to not block the UI for this type of work, as to me it screams using threads, but I know UIKit is not meant to be used from other threads. (I know NSString is not part of UIKit, but the string sizing methods are part of the UIKitAdditions...) So how should I go about doing this? What's the best way to not block the UI and do so safely?

• Starting work on a Pre-existing Project

  - by Toymakerii

  So this is more of a generic question. I seem to keep finding myself being put on larger and larger projects. Recently I have been assigned to a very large project written in C and VHDL. The goal is for me to become familiar with the code and eventually take the lead on the project. This is by far the largest project I have been assigned to work on that I didn't start. So here is my question: What methods/tools do you use to learn how everything works? Do you just increase and expand on comments? Do you make a UML representation of the project? Any tips would be great! Thanks

• Multi Action with Form design streatgy

  - by Ravi

  Hello All, I want to have a controller that can handle multiple requests. Like a UserController handling all the addUser, deleteUser, updateUser and viewUser functionality. I know that MultiActionController can be used to bundle multiple similar request into one controller. But the functionalities like addUser and updateUser involves user to enter data, which the controller need to process. Can a MultiActionController handle doSubmit kind of methods (similar to SimpleFormController). Is there any better way to handle this kind of scenario? Thanks. Ravi

• What some good books on software testing/quality?

  - by mjh2007

  I'm looking for a good book on software quality. It would be helpful if the book covered: The software development process (requirements, design, coding, testing, maintenance) Testing roles (who performs each step in the process) Testing methods (white box and black box) Testing levels (unit testing, integration testing, etc) Testing process (Agile, waterfall, spiral) Testing tools (simulators, fixtures, and reporting software) Testing of embedded systems The goal here is to find an easy to read book that summarizes the best practices for ensuring software quality in an embedded system. It seems most texts cover the testing of application software where it is simpler to generate automated test cases or run a debugger. A book that provided solutions for improving quality in a system where the tests must be performed manually and therefore minimized would be ideal.

• Take screenshot of DirectX full-screen application

  - by iconiK

  This boggles me. DirectX bypasses everything and talks directly to the device driver, thus GDI and other usual methods won't work - unless Aero is disabled (or unavailable), all that appears is a black rectangle at the top left of the screen. I have tried what other have suggested on several forums, using DirectX to get the back buffer and save it, but I get the same result: device-GetFrontBufferData(0, surface); D3DXSaveSurfaceToFile("fileName", D3DXIFF_BMP, surface, NULL, NULL); Is there any way to get a screenshot of another full-screen DirectX application when Aero is enabled?

• Graph databases and Php

  - by stagas

  I want to use a graph database using php. Can you point out some resources on where to get started? Is there any example code / tutorial out there? Or are there any other methods of storing data that relate to each other in totally random/abstract situations? Very abstract example of the relations needed: John relates to Mary, both relate to School, John is Tall, Mary is Short, John has Blue Eyes, Mary has Green Eyes, query I want is which people are related to 'Short people that have Green Eyes and go to School' - answer John It is possible in MySQL but it would require a fixed set of attributes/columns for each item and a complex non-flexible query, instead I need every attribute to be an item by itself and instead of 'belonging' to something, to be 'related' to something.

• Changing a Container while using Visitor

  - by Florian

  Hi everyone, I implemented the Visitor pattern in C++ using a STL-like iterator for storing the Visitor's current position in the container. Now I would like to change the container while I iterate over it, and I'm especially interested in deleting items from the container, even the one I'm currently visiting. Now obviously this will invalidate the Visitors internal iterator, because it was pointing to exactly this item. Currently, I store a list of all iterators in the container and update them, as soon as anything is added to or removed from the list. So in a way this is similar to the Observer pattern applied to the iterator (as Observer) and the list (as Observable). Alternatively I considered having the visitor() methods return some hint to the Visitor about what happend to the current item and how to proceed iterating, but that doesn't sound like such a good idea either, because the visit() implementation shouldn't really care about finding the next item. So, my question is: What's the best way to keep a visitor working, even when items are added to the container or removed from it. Regards, Florian

• Why does my UITableView change from UITableViewStyleGrouped to UITableViewStylePlain

  - by casper

  My application has a view controller that extends UITableViewController. The initialization method looks like this: - (id)initWithCoder:(NSCoder*)coder { if (self = [super initWithCoder:coder]) { self.tableView = [[UITableView alloc] initWithFrame:self.tableView.frame style:UITableViewStyleGrouped]; } return self; } When the view is initially loaded, it's displayed as UITableViewStyleGrouped. However, if my app ever receives a low memory warning, the above view changes to UITableViewStylePlain. There is no associated xib file with the View/Controller. The viewDidUnload and didReceiveMemoryWarning methods are straightforward: - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } My question is, why does the table style change when I receive a memory warning?

• Using WCF authentication service for web application

  - by user200295

  I am using a WCF authentication service I set up with a web application. I have successfully set up and tested the AuthenticationService and RolesService. The web application can successfully call methods like ValidateUser and GetRolesForCurrentUser through the WCF services. I want to integrate the WCF authentication service with my web.config and site.map. Do I need to write a custom provider, or is there some way I can modify the web.config of the web application to use the WCF authentication service as its membership provider? This way I can set what roles have access to what directories based off the WCF authentication service.

• WSDL: What do I do with it? Add service Reference? Noobie question

  - by Johnny

  Hey guys! I have been given a WSDL with all the method requests and responses, and all the objects I'll need to use for creating a few webmethods. The thing is, I don't know what to do with it. I've added the WSDL as a Service Reference. I can see the methods and structures, I can instantiate them, it's all there, but the project doesn't build as soon as I add the WSDL. "Error 2 The type name 'ServiceReference1' does not exist in the type 'WSPELab.WSPELab' C:\Users\JJ\Documents\Visual Studio 2008\Projects\WSPELab\WSPELab\Service References\ServiceReference1\Reference.cs 21 111 WSPELabSLN Is it a stupid namespace error on my part? EDIT : Forgot to add this. With the WSDL added, can I used the structures it contains directly? Or are they just "listings" for me to implement? Thanks!

• wxruby - Set max length of ComboBox

  - by Jonas Söderström

  Is is possible to set the Max length of a ComboBox in wxruby? I have looked in the documentation but find nothing http://wxruby.rubyforge.org/doc/combobox.html But if i do my_combobox.methods.sort I get set_max_size and set_min_size in the list. But When I call it my_combobox.set_max_length(100) I only get undefined method 'set_max_length' for #<Wx::ComboBox:0x4d4a914> I've also tried to call it as a private method def my_combobox.max(i) set_max_length(i) end my_combobox.max(100) But with the same result. The issue I want to avoid is that if somebody pastes 6000+ characters in my Combobox the text becomes white.

• UITableView, force to snap to whole UITableViewCell at top of table

  - by Adam Eberbach

  I have a need to make a UITableView only display whole cells at the top of the cell, so when the table is moved or scrolled it should animate to make a whole cell visible at the top of the table if it has happened to stop with a cell partially off the top. This can be easily done using visibleCells and scrollToRowAtIndexPath methods of UITableView, BUT the cell should not always scroll down to move the partial cell into view - if the cell at top is more than 50% gone it should go completely with the next cell (i.e. index 1 in the array returned by visibleCells) moving to the top of the table. I've tried a few things to make this happen but I don't think I am understanding the way frame and bounds work between a UITableView and its UITableViewCells. Any help?

• Sharepoint and SQL server Endpoint

  - by Usman Ahmad

  I created a LinkedServer on MS SQL Server 2005 pointing to my Active Directory. Nothing too fancy. Simple LinkedServer with ReadOnlyAdmin Account assigned to CONNECTAS Property. Then I created some storedprocedures to retreive some data from the LinkedServer. Again nothing too fancy. Just a few simple LDAP Queries. Then I created a SQL Endpoint to expose these stored procedures as Web services. Using Visual Studio 2008, everything is fine and dandy. It finds the endpoint, gets the list of the methods available and runs smoothly. Cool. But the Sharpeoint Add Web Service somehow doesn't work! It finds the WSDL file no prob. Retrieves the list of functions and parameterss n all but just simply doesn't run them! Any advice or where I should start checking?

• problems with user control page

  - by Alexander

  I am starting to give up troubleshooting this issue I had... I had an .ascx page and had the following user control in it: <td> <Club:DatePicker ID="dp1" runat="server" /> </td> however in my code behind when I tried to write methods: public System.DateTime startDateTime { get { return dp1.SelectedDate.Add(tp1.SelectedTime.TimeOfDay); } set { dp1.SelectedDate = value; tp1.SelectedTime = value; } } It can't reference dp1(dp1 is underlined in red) as well as tp1... why is this?? I've tried to convert the solution to a web application and yet it doesn't work. Tried adding: protected global::ClubSite dp1; protected global::ClubSite tp1; in the ascx.designer.cs but then the global is highlighted in red here's the link to my full solution: http://cid-1bd707a1bb687294.skydrive.live.com/self.aspx/.Public/Permias.zip

• Changing an extention method from linq-to-sql to entity framework

  - by Jova

  I'm changing my project from working with Linq-to-SQL to working with Entity Framework. I have some extention methods that extend the classes created by LINQ and I'm wondering how to change them to work with the entities instead Here's an example. public static int GetPublishedArticlesCount(this Table<Article> source) { return GetPublishedArticles(source.Context as DataContext, null).Count(); } This method gets the number of published articles. Instead of using this Table<Article>, what should I use instead?

• How to properly use .SWC packages in Flash CS 4

  - by DevEight

  Hi! I've googled a lot trying to find how to properly import and use .swc files in Flash CS 4, tried lots of different methods but none seem to work. What I've done is: 1. Placed it in my "D:\Program Files (x86)\Adobe\Adobe Flash CS4\en\Configuration\Components" folder. It does however not show up in the component inspector. 2. Added it in Publishing Settings as a Library and External Library, still can't seem to use it. I've also tried adding "import org.osflash.signals;" after each method but I receive the error "1172: Definition org.osflash:signals could not be found." So what I'm asking for is an easy way to get the .swc package working code-wise with all classes imported etc. The .swc file is as you may have guessed as3signals. Thanks in advance.

• How to get hold of the current NHibernate.Cfg.Configuration instance.

  - by Sandor Drieënhuizen

  My C# project has repositories that are instantiated using dependency injection. One of the repository methods needs access to the NHibernate.Cfg.Configuration instance (to generate the database schema) that was returned when initializing NHibernate. I cannot pass the configuration to the repository however, because that would break the persistence ignorance principle -- I really don't want to expose any implementation details through the repository interface. So what I'm looking for is a way of getting hold of the current NHibernate.Cfg.Configuration instance from within my repository. I have no trouble getting hold of the current session, it's just the configuration that I cannot get hold of.
