• Embedded AXIS2: Serving a custom WSDL

  - by Maik

  I am using a console app that starts several axis instances without using a packages archive. Like this: AxisService axisService2 = AxisService.createService( new Myclass.getClass().getName(), axisConfigurationContext.getAxisConfiguration()); axisService2.addParameter(new Parameter("useOriginalwsdl", "true")); axisConfigurationContext.getAxisConfiguration().addService(axisService2); Now, I need to serve a custom WSDL. I tried adding a META-INF folder to the bin-root, and in various other places, but with no success. How do I specify in this case the location of a custom WSDL? Thanks!

• Cannot await 'Model.PersonalInfo'

  - by Gooftroop

  I have the following method in a DesignDataService class public async Task<T> GetData<T>(T dataObject) { var typeName = typeof(T).Name; switch (typeName) { case "PersonalInfo": var person = new PersonalInfo { FirstName = "Mickey", LastName = "Mouse" , Adres = new Address{Country="DLRP"} , }; return await person; } // end Switch } // GetData<T> How can I return a new PersonalInfo class from the DataService? For now I get the error Cannot await 'Model.PersonalInfo' Even when I change the return statement as follows return await person as Task; the error stays the same Thanks in advanced Danny

• Using Parallel Extensions with ThreadStatic attribute. Could it leak memory?

  - by the-locster

  I'm using Parallel Extensions fairly heavily and I've just now encountered a case where using thread locla storrage might be sensible to allow re-use of objects by worker threads. As such I was lookign at the ThreadStatic attribute which marks a static field/variable as having a unique value per thread. It seems to me that it would be unwise to use PE with the ThreadStatic attribute without any guarantee of thread re-use by PE. That is, if threads are created and destroyed to some degree would the variables (and thus objects they point to) remain in thread local storage for some indeterminate amount of time, thus causing a memory leak? Or perhaps the thread storage is tied to the threads and disposed of when the threads are disposed? But then you still potentially have threads in a pool that are longed lived and that accumulate thread local storage from various pieces of code the threads are used for. Is there a better approach to obtaining thread local storage with PE? Thankyou.

• How to effectively measure developer's work hours?

  - by twk

  I have a few software developers working for my projects and I would like to provide them a way to register time they spent on real development. There is good will to register development hours, no force, but we try to avoid techniques like excel sheets register because this is so uncomfortable. I can track svn commits, but this is unreliable. Developers also helps supporting different projects during the day, so assuming they work on one project by whole day is not true. I've seen utilities that popups a message every hour to confirm the project you're working on but this is annoying. Some kind of active-window-title-anaylzer might help (you can get solution name from there in the case of Visual Studio) but I have no experience with such idea. If you have any experience with programmers/designers work hours registration, please share with me. Thanks

• How to debug unreleased COM references from managed code?

  - by Marek

  I have been searching for a tool to debug unreleased COM references, that usually cause e.g. Word/Outlook processes to hang in memory in case the code does not call Marshal.ReleaseCOMObject on all COM instances correctly. (Outlook 2007 partially fixes this for outlook addins, but this is a generic question). Is there a tool that would display at least a list of COM references (by type) held by managed code? Ideally, it would also display memory profiler-style object trees helping to debug where the reference increment occured. Debugging at runtime is not that important as being able to attach to a hung process - because the problem typically occurs when the code is done with the COM interface and someone forgot to release something - the application (e.g. winword) hangs in memory even after the calling managed application quits. If such tool does not exist, what is the (technical?) reason? It would be very useful for debugging a lot of otherwise very hard to find problems when working with COM interop.

• Flex TextArea leading invalid

  - by Andreas

  Hi, When I set leading to 0 with Verdana (and others to) for a Flex TextArea I get strange results: fontsize - space between baselines 8 - 10 (125%) 10 - 12 (120%) 12 - 14 (117%) 14 - 17 (121%) 16 - 18 (113%) 18 - 22 (122%) 20 - 25 (125%) 25 - 31 (124%) shouldn't all of these be the same (should only be 100%)? Or least follow a pattern, because I can't se any. :( When i set leading to 0, the space between my baselines should be the same as the font size/height. This is not the case here. How do I know how to get the space between the baseline to be equal to the height of the font?

• Rotating text in postscript

  - by Mrgreen

  I have the following postscript code: /outputtext { /data exch def /rot exch def /xfont exch def /Times-Roman findfont xfont scalefont setfont /y1 exch def /x1 exch def x1 y1 moveto rot rotate data show } def % x y fontsize rotation (text) outputtext 20 300 12 0 (text1) outputtext 20 400 12 90 (text2) outputtext 20 500 12 90 (text3) outputtext 20 600 12 0 (text4) outputtext showpage The function simply outputs text based on a x, y co-ords and the text to display, there is also a variable for rotation. For some reason when I output text with a rotation of 0 degrees, all other text that comes after that will not work, I can't seem to figure out why this is the case. In the example above, 'text1' and 'text2' will display, but not 3 and 4.

• Possible typos in ECMAScript 5 specification?

  - by Andy West

  Does anybody know why, at the end of section 7.6 of the ECMA-262, 5th Edition specification, the nonterminals UnicodeLetter, UnicodeCombiningMark, UnicodeDigit, UnicodeconnectorPunctuation, and UnicodeEscapeSequence are not followed by two colons? From section 5.1.6: Nonterminal symbols are shown in italic type. The definition of a nonterminal is introduced by the name of the nonterminal being defined followed by one or more colons. (The number of colons indicates to which grammar the production belongs.) Since lexical productions are distinguished by having two colons, and this is under "Lexical Conventions", I'm assuming that they meant to put the colons in. Does that sound right? Just making sure that these really are nonterminals and they really are part of the lexical grammar. EDIT: I noticed there have been votes to close this. Just to make my case about why this is programming-related, it is relevant to anyone wanting to implement an ECMAScript interpreter.

• cakephp VS codeigniter VS zend framework

  - by i need help

  Very possibly very related: What PHP framework would you choose for a new application and why? Zend or CakePHP? Which one is better? Some people say CakePHP is better for php 4, what do you think? In my case, I would like the following: Lesser code to write, have really strong library and plugin base. Always have new library etc added in from contributor, eg: google map and etc... Ability to use together with the templating system like smarty. Have ACL that can control all the permission level issue. Load class when needed, unload when not needed. Load class once and use globally. Can run in windows environment (I am using xampp to run my php in windows.) After the site done, I will upload all codes into windows 2008 server (using php 5)

• Indy 10 FTP empty list

  - by Lobuno

  Hello! I have been receiving reports from some of my users that, when using idFTP.List() from some servers (MS FTP) then the listing is received as empty (no files) when in reality there are (non-hidden) files on the current directory. May this be a case of a missing parser? The funny think, when I use the program to get the list from MY server (MSFTP on W2003) everything seems OK but on some servers I've been hitting this problem. Using latest Indy10 on D2010. Any idea?

• Adding help button for each window

  - by Miraaj

  Hi all, I have found that user can associate help with his application using Help Viewer. Users typically launch Help Viewer by choosing the application help item from the Help menu, or by typing a query in the Spotlight For Help text field in the Help menu. I have some different requirement: I want to associate component specific help to my application, means that there will be a small '?' marked icon at bottom left corner of a window and when user clicks it, appropriate help page will open. This case is similar to 'print' panels where there is a small '?' icon. Can anyone suggest me some way to accomplish it, if it is possible? Thanks, Miraaj

• Someone is using the struct name as a variable name too. What does the code really say? (c++)

  - by EvilTeach

  This morning we found an old chunk of code that was causing a library call to crash. struct fred { int a; int b; int c; }; fred fred[MAX_SIZE+1]; memset( fred, 0, sizeof(fred) * MAX_SIZE+1 ); It appears that the sizeof(fred) may have been the full array size, rather than the structure size, as it was overwriting a great deal of memory. The fact that it compiled without warning on several different systems seemed odd. Is there a correct semantic for this case where the type and variable name are colliding? or is this some sort of undefined behavior? or just a defect? I haven't been been clever enough to find anything on Google or our language help. Thanks Evil

• Castle Windsor - Resolving a generic implementation to a base type

  - by arootbeer

  I'm trying to use Windsor as a factory to provide specification implementations based on subtypes of XAbstractBase (an abstract message base class in my case). I have code like the following: public abstract class XAbstractBase { } public class YImplementation : XAbstractBase { } public class ZImplementation : XAbstractBase { } public interface ISpecification<T> where T : XAbstractBase { bool PredicateLogic(); } public class DefaultSpecificationImplementation : ISpecification<XAbstractBase> { public bool PredicateLogic() { return true; } } public class SpecificSpecificationImplementation : ISpecification<YImplementation> { public bool PredicateLogic() { /*do real work*/ } } My component registration code looks like this: container.Register( AllTypes.FromAssembly(Assembly.GetExecutingAssembly()) .BasedOn(typeof(ISpecification<>)) .WithService.FirstInterface() ) This works fine when I try to resolve ISpecification<YImplementation>; it correctly resolves SpecificSpecificationImplementation. However, when I try to resolve ISpecification<ZImplementation> Windsor throws an exception: "No component for supporting the service ISpecification'1[ZImplementation, AssemblyInfo...] was found" Does Windsor support resolving generic implementations down to base classes if no more specific implementation is registered?

• Cost of using repeated parameters

  - by Palimondo

  I consider refactoring few method signatures that currently take parameter of type List or Set of concrete classes --List[Foo]-- to use repeated parameters instead: Foo*. This would allow me to use the same method name and overload it based on the parameter type. This was not possible using List or Set, because List[Foo] and List[Bar] have same type after erasure: List[Object]. In my case the refactored methods work fine with scala.Seq[Foo] that results from the repeated parameter. I would have to change all the invocations and add a sequence argument type annotation to all collection parameters: baz.doStuffWith(foos:_*). Given that switching from collection parameter to repeated parameter is semantically equivalent, does this change have some performance impact that I should be aware of? Is the answer same for scala 2.7._ and 2.8?

• Where has my parallel port gone? ioperm(888,1,1) returns -1.

  - by marcusw

  I have an old Dell Dimension 8200 running Gentoo which I use solely to control various things using the parallel port. After shutting it down a few weeks ago, I started it up again today and tried to access the parallel port like I usually do. Unfortunately, my code bombed out when it tried to call ioperm(888,1,1) to grab the parallel port which returned an error code of -1. There have been no changes to the system be it hardware or software, no updates, no tweaking, no dropping the case, no over-amping the data pins, nothing. The port and the software have been working fine for months with no changes, and were working fine when I shut it down last. Running my code with root privileges changes nothing. What is breaking this and how can I fix it?

• Integer comparison as string

  - by J Pollack

  Hi I have an integer column and I want to find numbers that start with specific digits. For example they do match if I look for '123': 1234567 123456 1234 They do not match: 23456 112345 0123445 Is the only way to handle the task by converting the Integers into Strings before doing string comparison? Also I am using Postgre regexp_replace(text, pattern, replacement) on numbers which is very slow and inefficient way doing it. The case is that I have large amount of data to handle this way and I am looking for the most economical way doing this.

• How to capture shift-tab in vim

  - by Yogesh Arora

  I want to use shift-tab for auto completion and shifting code blocks visually. I have been referring to Make_Shift-Tab_work . That link talks about mapping ^[[Z to shift-tab . But i don't get ^[[Z when i press shift-tab. i just get a normal tab in that case. It then talks about using xmodmap -pke | grep 'Tab' to map tab keys. According to that the output should be keycode 23 = Tab or keycode 23 = Tab ISO_Left_Tab However i get keycode 22 = Tab KP_Tab if i use xmodmap -e 'keycode 22 = Tab ISO_Left_Tab' and after that xmodmap -pke | grep 'Tab', I still get keycode 22 = Tab KP_Tab This means running xmodmap -e 'keycode 22 = Tab ISO_Left_Tab' has no effect. In the end the link mentions using xev to see what X recieves when i press shift-tab. But i dont have xev on my system. Is there any other way i can capture shift-tab in vim

• Finding the TextBlock that is part of the default control template ComboBox generated through code.

  - by uriya

  I'm trying to find the TextBlock that is inside the control template of a comboBox. using VisualTreeHelpar.GetChildrenCount is working only if the comboBox is declared in XAML.In that case GetChildrenCount returns 1 and a recursive search is possible. However, if I declare the combo as a member of the Window class using code, allocated and setting it to its place, the function GetChildrenCount return 0. When I run snoop in this scenario It shows the combo children hierarchy. I want to be able to search the comboBox just as snoop does. Any help would be appreciated. code: ComboBox mCombo = null; private void Windows_Loaded(object sender, RoutedEventArgs e) { mCombo = new ComboBox; mGrid.Children.Add(mCombo); Grid.SetRow(mCombo,0); int count = VisualTreeHelpar.GetChildrenCount(mCombo); }

• Providing multi-version databases for backward compatibility for production applications/databases.

  - by JavaRocky

  How can I manage multiple versions of a database easily? I have some data (as views as selects for data originating in tables from other schemas), which other database may reference using various means including database synonyms & links. I wish to provide a sort of interface/guarantee in-case future for applications/databases which use this data. All of this is for in the event i need to update the views for correctness or applicability inside my database. How can i achieve this in a maintained, controlled and easy way? I am using Oracle 10g if that matters.

• http(/* argument here */) How is this Object (Http) being used without an explicit or implicit meth

  - by Randin

  In the example for coding with Json using Databinder Dispatch Nathan uses an Object (Http) without a method, shown here: import dispatch._ import Http._ Http("http://www.fox.com/dollhouse/" >>> System.out ) How is he doing this? Thank you for all of the answers unfortunatly I was not specific enough... It looks like it is simply passing an argument to a constructor of class or companion object Http. In another example, I've seen another form: http = new Http http(/* argument here */) Is this valid Scala? I guess it must be, because the author is a Scala expert. But it makes no sense to me. Actions are usually performed by invoking methods on objects, whether explicitly as object.doSomething() or implicitly as object = something (using the apply() method underneath the syntactic sugar). All I can think of is that a constructor is being used to do something in addition to constructing an object. In other words, it is having side effects, such as in this case going off and doing something on the web.

• Is It Possible To Use Javascript/CSS To Swap Style Sheets When A Mobile Device Rotates?

  - by Sean M

  I am working on a site that must be designed with mobile accessibility in mind. As part of our brainstorming, we wondered whether it's possible to detect, for a mobile browser (i.e. Mobile Safari or the Android browser), when the viewing device has changed orientation, and to use that as a trigger to change page content? As the title of this question implies, our best-case scenario is the ability to detect the orientation change and use it to alter the CSS on the fly so as to present a slightly different page for landscape versus portrait. Of course we can just design for a page that looks good one way and make it obvious that it's supposed to be viewed that way, but the cool-stuff factor of a page that looks good either way is pretty appealing. Is this idea implementable? Practical?

• .aspx character coding

  - by kwek-kwek

  I am having an problem. First time working with a windows server, do you know if there is any problem in character coding? My document is set to content="text/html; charset=UTF-8" but it's giving me funny words... you can check it here. This site is a pure HTML with few includes but anything else is just HTML. I can convert them to HTML entities but that is basically wasting my time. I never had this problem with any website I did except for this. Some others said "The problems seems to be that you have converted the text into utf-8 twice.". But how would Coverted it twice since dreamweaver should convert it for me but in this case it doesn't.

• [Python] Detect destination of shortened, or "tiny" url

  - by conradlee

  I have just scraped a bunch of Google Buzz data, and I want to know which Buzz posts reference the same news articles. The problem is that many of the links in these posts have been modified by URL shorteners, so it could be the case that many distinct shortened URLs actually all point to the same news article. Given that I have millions of posts, what is the most efficient way (preferably in python) for me to detect whether a url is a shortened URL (from any of the many URL shortening services, or at least the largest) Find the "destination" of the shortened url, i.e., the long, original version of the shortened URL. Does anyone know if the URL shorteners impose strict request rate limits? If I keep this down to 100/second (all coming form the same IP address), do you think I'll run into trouble?

• .NET PostSubmitter sends backslashes

  - by Stefan N.

  Hi, I'm using C# to send JSON to a PHP-Script, like this: string json = "{"; json += "\"prop\":\"some text\""; json += "}"; PostSubmitter post = new PostSubmitter(); post.Url = "http://localhost/synch/notein.php"; post.Type = PostSubmitter.PostTypeEnum.Post; post.PostItems.Add("note", json); post.Post(); Of course I'll have to escape the inner quotes, but they get sended to the script! To make things worse: There is text, which already has quotation marks, so those must be escaped to be valid JSON. In this case I want the backslashes to be transmitted. Any idea to accomplish this?
