  • Recoverable error while running XSL

  • Difference in calling redefined functions in F# and Clojure

    - by Michiel Borkent
    In F#: > let f x = x + 2;; val f : int -> int > let g x = f x;; val g : int -> int > g 10;; val it : int = 12 > let f x = x + 3;; val f : int -> int > g 10;; val it : int = 12 In Clojure: (defn f [x] (+ x 2)) (defn g [x] (f x)) (g 10) ;; => 12 (defn f [x] (+ x 3)) (g 10) ;; => 13 Note that in Clojure the most recent version of f gets called in the last line. In F# however still the old version of f is called. Why is this?

  • Can I have two names for the same variable?

    - by Roman
    The short version of the question: I do: x = y. Then I change x, and y is unchanged. What I want is to "bind" x and y in such a way that I change y whenever I change x. The extended version (with some details): I wrote a class ("first" class) which generates objects of another class ("second" class). In more details, every object of the second class has a name as a unique identifier. I call a static method of the first class with a name of the object from the second class. The first class checks if such an object was already generated (if it is present in the static HashMap of the first class). If it is already there, it is returned. If it is not yet there, it is created, added to the HashMap and returned. And then I have the following problem. At some stage of my program, I take an object with a specific name from the HashMap of the first class. I do something with this object (for example change values of some fields). But the object in the HashMap does not see these changes! So, in fact, I do not "take" an object from the HashMap, I "create a copy" of this object and this is what I would like to avoid.

  • How can I compile .NET 3.5 C# code on a system without Visual Studio?

    - by JimEvans
    I have some C# code that uses some constructs specific to .NET 3.5. When you install the .NET Framework distribution, you get the C# compiler installed with it (csc.exe). Even if I specify the csc.exe in C:\Windows\Microsoft.NET\Framework\v3.5, I cannot compile the code on a computer with only the .NET Framework installed, but not Visual Studio. I am able to compile code that uses v2.0 constructs without difficulty. How can I accomplish this? Here is a sample that demonstrates my problem: using System; class Program { public static void Main() { // The MacOSX value to the PlatformID enum was added after // .NET v2.0 if (Environment.OSVersion.Platform == PlatformID.MacOSX) { Console.WriteLine("Found mac"); } Console.WriteLine("Simple program"); } } When compiling this code using csc.exe, I receive the following error: test.cs(9, 58): error CS0117: 'System.PlatformID' does not contain a definition for 'MacOSX' When executing csc.exe /? I receive the banner: Microsoft (R) Visual C# 2008 Compiler version 3.5.21022.8 for Microsoft (R) .NET Framework version 3.5 Copyright (C) Microsoft Corporation. All rights reserved.

  • WCF service not working after program update

    - by Boesj
    I have recently added a WCF service reference to my program. When I perform a clean install of this program, everything seems to work as expected. But, when I install the program on a client which already has a previous version (without the new service reference) installed, I get a exception telling me the default endpoint for this particular service could not be found. It seems that the appname.exe.config is not being updated with the new endpoint settings. Is there any reason for this and how can I force the installer to overwrite the config file? I'm using the default Visual Studio 2008 installer project with RemovePreviousVersions set to True. Update: My program encrypts the settings section after the first run with the following code Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); ConfigurationSection section = config.GetSection(sectionKey); if (section != null) { if (!section.SectionInformation.IsProtected) { if (!section.ElementInformation.IsLocked) { section.SectionInformation.ProtectSection("DataProtectionConfigurationProvider"); section.SectionInformation.ForceSave = true; config.Save(ConfigurationSaveMode.Full); } } } When I do not run the program before installing the new version the app.config gets updated.

  • Reading the .vcproj file with C#

    - by Dulantha Fernando
    We create the vcproj file with the makefileproj keyword so we can use our own build in VS. My question is, using C#, how do you read the "C++" from the following vcproj file: <?xml version="1.0" encoding="Windows-1252"?> <VisualStudioProject ProjectType="Visual C++" Version="8.00" Name="TestCSProj" ProjectGUID="{840501C9-6AFE-8CD6-1146-84208624C0B0}" RootNamespace="TestCSProj" Keyword="MakeFileProj" > <Platforms> <Platform Name="x64" /> <Platform Name="C++" ===> I need to read "C++" /> </Platforms> I used XmlNode and got upto the second Platform: String path = "C:\\blah\\TestCSProj\\TestCSProj\\TestCSProj.vcproj"; FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); XmlDocument xmldoc = new XmlDocument(); xmldoc.Load(fs); XmlNodeList oldFiles = xmldoc.GetElementsByTagName("Platform"); XmlAttribute name = oldFiles[1].Attributes[0]; Console.WriteLine(name.Name); This will print Name, but I need "C++". How do I read that? Thank you very much in advance

  • XSLT - Comparing preceding-sibling's elements with current's node element

    - by siondream
    Hello, I have this XML file: <recursos> <recurso url="http://w3c.com"> <descripcion>Consorcio W3C</descripcion> <tipo>externo</tipo> <idioma>ingles</idioma> <contenido>General</contenido> <unidad>Unidad 2</unidad> </recurso> <recurso url="http://html.com"> <descripcion>Especificación HTML</descripcion> <tipo>externo</tipo> <idioma>castellano</idioma> <contenido>HTML</contenido> <version>4.01</version> <unidad>Unidad 3</unidad> </recurso> </recursos> I want to compare one "recurso"'s preceding sibling element "unidad" with the "unidad" of the current "recurso" to check if they're different. I was trying: <xsl:if test="preceding-sibling::recurso[position()=1]::unidad != unidad"> </xsl:if> But I know it's horribly wrong :( I hope you could help me, thank you very much.

  • Cannot generate/run migrations on rails 2.3.4

    - by Brian Roisentul
    I used to work with rails 2.3.2 before and then I decided to upgrade to version 2.3.4. Today I tried to generate a migration(I could do this fine with version 2.3.2) and I got the following error message: C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/gems/1.8/gems/rails-2.3.4/lib/initializer.rb:812:in `const_missing': uninitialized constant ActiveSupport (NameError) from D:/Proyectos/Cursometro/www/config/environment.rb:33 from C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/gems/1.8/gems/rails-2.3.4/lib/initializer.rb:111:in `run' from D:/Proyectos/Cursometro/www/config/environment.rb:15 from D:/Proyectos/Cursometro/www/config/environment.rb:31:in `require' from C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' from C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/gems/1.8/gems/rails-2.3.4/lib/commands/generate.rb:1 from C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/gems/1.8/gems/rails-2.3.4/lib/commands/generate.rb:31:in `require' from C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' from script\generate:3 I don't know why this is happening.

  • Flex 3 (Action Script): How to access a function from a loaded swf-file ?

    - by Trantec
    Hi, i load in ActionScript a swf file. So far no Problem, but I didn't found a way to access one of it's functions, the best thing would be if I could access the main function in the mxml part of the swf. Here is the code of the main-mxml file that belongs to the swf that should load and access another swf: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="basket();"> <mx:Script> <![CDATA[ import mx.controls.SWFLoader; private function basket(): void { var swfLoader: SWFLoader = new SWFLoader(); swfLoader.addEventListener( Event.COMPLETE, handleSWFLoaded ); try { swfLoader.load( "../../data/InternalSWF.swf" ); } catch (error: Error) { trace( "Couldn't load file !" ); } } private function handleSWFLoaded( event: Event ): void { var swfApp:* = event.target.content; // This both ways don't work... //if (swfApp.hasOwnProperty("initApp")) { // var initApp:Function = (swfApp["initApp"] as Function); // initApp(); //} // swfApp.initApp(); } ]]> </mx:Script> <mx:Text id="output" width="100%" textAlign="center" /> </mx:Application> The if-Statement "if (swfApp.hasOwnProperty("initApp")) {" is never true and the call "swfApp.initApp()" says that this function does not exist. In the original version I added event listeners for HTTPStatusEvent.HTTP_STATUS, IOErrorEvent.IO_ERROR and SecurityErrorEvent.SECURITY_ERROR. But except for HTTP_STATUS = 0 none of them are called. Is the whole idea of how i try to do this wrong ?

  • CXF code first service, WSDL generation; soap:address changes?

    - by jcalvert
    I have a simple Java interface/implementation I am exposing via CXF. I have a jaxws element in my Spring configuration file like this: <jaxws:endpoint id="managementServiceJaxws" implementor="#managementService" address="/jaxws/ManagementService" > </jaxws:endpoint> It generates the WSDL from my annotated interface and exposes the service. Then when I hit http://myhostname/cxf/jaxws/ManagementService?wsdl I get a lovely WSDL. At the bottom in the wsdl:service element, I'll see <soap:address location="http://myhostname/cxf/jaxws/ManagementService"/> However, some time a day or so later, with no application restart, hitting that same url produces: This causes a number of problems, but what I really want is to fix it. Right now, there's a particular client to the webservice that sets the endpoint to localhost; because it runs on the same machine. Is it possible the wsdl is getting regenerated and cached and then exposing the 'localhost' version? In part I don't know the exact mechanism by which one goes from a ?wsdl request in CXF to the response. It seems almost certain that it's retrieving some cached version, given that it's supposed to be determining the address by asking the servletcontainer (Jetty). For reference I know a stopgap solution is using the hostname on the client and making sure an alias in place so that it goes over the loopback. EDIT: For reference, I confirmed that if I bring my application up and first hit it over localhost, then querying for the wsdl via the hostname shows the address as localhost. Conversely, first hitting it over the hostname causes localhost requests to show the hostname. So obviously something is getting cached here.

  • Git rebase and semi-tracked per-developer config files.

    - by dougkiwi
    This is my first SO question and I'm new-ish to Git as well. Background: I am supposed to be the version control guru for Git in my group of about 8 developers. As I don't have a lot of Git experience, this is exciting. I decided we need a shared repository that would be the authoritative master for the production code and the main meeting-point for the development code. As we work for a corporation, we really do need to show an authoritive source for the production code at least. I have instructed the developers to pull-rebase when pulling from the shared repository, then push the commits that they want to share. We have been running into problems with a particular type of file. One of these files, which I currently assume is typical of the problem, is called web.config. We want a version-controlled master web.config for devs to clone, but each dev may make minor edits to this file that they wish to locally save but not share. The problem is this: how do I tell git not to consider local changes or commits to this file to be relevent for rebasing and pushing? Gitignore does not seem to solve the problem, but maybe that's because I put web.config into .gitignore too late? In some simple situations we have stacked local changes, rebased, pushed, and popped the stack, but that doesn't seem to work all of the time. I haven't picked up the pattern quite yet. The published documentation on pull --rebase tends to deal with simplier situations. Or do I have the wrong idea entirely? Are we misusing Git? Dougkiwi

  • Invalid Argument javascript error only on certain computers

    - by Jen
    Getting an error whenever we click a particular button/link on our site. It is generating a javascript "Invalid Argument" error. I know in the other posts it is typically because it is a syntax error in the javascript however it only just seems to have started happening and it doesn't happen on all pcs. ie. in our client's environment if I remote onto their web server and view the uat website I get the javascript error. If I remote onto their sql server and view the uat website I don't get the javascript error. If it was a syntax error then I would always get the error wouldn't I? both browsers are the same version of IE6 (yeah I know...) :) I have tried deleting temporary internet files - including viewing the files and deleting them myself - but no joy. client uses citrix.. and they're all getting the error :( Any ideas would be appreciated - Thanks! :) Update - Sorry I haven't posted specific code as there is too much to post (and I'm not sure where the error is occurring). The "button" launches a new window which in turn opens up a couple of aspx pages and calls lots of javascript. So the window opens ok, and there's a function that gets called to resize the window - but before it calls the resizing of the window/content it throws the invalid argument error. Am busy trying to get alerts to trigger to see if I can see where it's falling over but so far no luck. Again not sure why this error doesn't occur when I use a particular PC (same browser version)

  • Maintenance tool for Application Database

    - by Thierry
    Hello ! Does anybody know about a good tool which help maintaining the database of an application ? I'm working on an application which uses a database (Microsoft Sql Server). When a development requires to change something in the database (e.g., structure, data migration...), we create a script (Transact-SQL script) and add it into our revision control tool (subversion - that tool also contains our code). Each script must add a line in a log table to keep a trace of all the scripts that have been ran into a database. In order to build a database for our application, one needs to run all scripts ordered by their creation date. I'm not really happy with this technique notably because it make application migration a bit hard. If we want to install a new version of the application somewhere, e.g., migrate from version 1.3 to 2.1, we must get all the scripts between these two versions. Then run them and ensure that everything is done in a transaction... For sure we could built home-made tools to help but I wonder if some tools already exists to do that kind of job.

  • optimistic and pessimistic locks

    - by billmce
    Working on my first php/Codeigniter project and I’ve scoured the ‘net for information on locking access to editing data and haven’t found very much information. I expect it to be a fairly regular occurrence for 2 users to attempt to edit the same form simultaneously. My experience (in the stateful world of BBx, filePro, and other RAD apps) is that the data being edited is locked using a pessimistic lock—one user has access to the edit form at the time. The second user basically has to wait for the first to finish. I understand this can be done using Ajax sending XMLHttpRequests to maintain a ‘lock’ database. The php world, lacking state, seems to prefer optimistic locking. If I understand it correctly it works like this: both users get to access the data and they each record a ‘before changes’ version of the data. Before saving their changes, the data is once again retrieved and compared the ‘before changes’ version. If the two versions are identical then the users changes are written. If they are different; the user is shown what has changed since he/she started editing and some mechanism is added to resolve the differences—or the user is shown a ‘Sorry, try again’ message. I’m interested in any experience people here have had with implementing both pessimistic and optimistic locking. If there are any libraries, tools, or ‘how-to’s available I’m appreciate a link. Thanks

  • How Best to Replace Ugly Queries and Dynamic PL/SQL with C#?

    - by Mike
    Hi, I write a lot of one-off Oracle SQL queries (in Toad), and sometimes they can get complex, involving lots of unions, joins, and subqueries, and sometimes requiring dynamic SQL. That is, sometimes SQL queries require set based processing along with significant procedural processing. This is what PL/SQL is custom made for, but as a language it does not begin to compare to C#. Now and then I convert a PL/SQL procedure to C#, and am always amazed at how much cleaner and easier to both read and write the C# version is. The C# program might for example construct a SQL query string piece by piece and/or run several queries and process them as needed. The C# version is usually much faster as well, which must mean that I'm not very good at PL/SQL either. I do not currently have access to LINQ. My question is, how best to package all these little C# programs, which are really just mini reports, that is, replacements for ugly SQL queries? Right now I'm actually using NUnit to hold them, and calling each report a [Test], even though they aren't really tests. NUnit just happens to provide a convenient packaging framework.

  • Why does the Maven goal "package" include the resources in the jar, but the goal "jar:jar" doesnt?

    - by Bernhard V
    Hi, when I package my project with the Maven goal "package", the resources are included as well. They are originally located in the directory "src/main/resources". Because I want to create an executable jar and add the classpath to the manifest, I'm using maven-jar-plugin. I've configured it as the following likes: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.2</version> <configuration> <archive> <manifest> <addClasspath>true</addClasspath> <mainClass>at.sozvers.stp.zpv.ekvkumsetzer.Main</mainClass> </manifest> </archive> </configuration> </plugin> Why won't the jar file created with "jar:jar" include my resources as well. As far as I'm concerned it should use the same directories as the "package" goal (which are in my case inherited from the Maven Super POM).

  • How to update to jersey 2.X on an app using jersey 1.1X?

    - by Maxrunner
    i recently faced a problem with the handling of exceptions using jersey. In this case it was that the exceptions thrown from Exception mapper are not re thrown to the underlaying container, i searched and found that this has been fixed in the 2.0 version. But i'm using jersey 1.10 and the 2.X dependencies are all different and its also maven based. Since this project is not using maven, how do i use the more recent version?In the 2.X versions there are no jackson json jars for example. So i'm having some doubts in how to upgrade. Here's my web.xml config entry for jerse <servlet> <servlet-name>Jersey REST Service</servlet-name> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> <init-param> <param-name>com.sun.jersey.config.property.packages</param-name> <param-value>com.mobile.rest.resources</param-value> </init-param> <init-param> <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name> <param-value>true</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Jersey REST Service</servlet-name> <url-pattern>/rest/*</url-pattern> </servlet-mapping> regards,

  • Replacing words in string

    - by abkai
    Okay, so I have the following little function: def swap(inp): inp = inp.split() out = "" for item in inp: ind = inp.index(item) item = item.replace("i am", "you are") item = item.replace("you are", "I am") item = item.replace("i'm", "you're") item = item.replace("you're", "I'm") item = item.replace("my", "your") item = item.replace("your", "my") item = item.replace("you", "I") item = item.replace("my", "your") item = item.replace("i", "you") inp[ind] = item for item in inp: ind = inp.index(item) item = item + " " inp[ind] = item return out.join(inp) Which, while it's not particularly efficient gets the job done for shorter sentences. Basically, all it does is swaps pronoun etc. perspectives. This is fine when I throw a string like "I love you" at it, it returns "you love me" but when I throw something like: you love your version of my couch because I love you, and you're a couch-lover. I get: I love your versyouon of your couch because I love I, and I'm a couch-lover. I'm confused as to why this is happening. I explicitly split the string into a list to avoid this. Why would it be able to detect it as being a part of a list item, rather than just an exact match? Also, slightly deviating to avoid having to post another question so similar; if a solution to this breaks this function, what will happen to commas, full stops, other punctuation? It made some very surprising mistakes. My expected output is: I love my version of your couch because you love I, and I'm a couch-lover. The reason I formatted it like this, is because I eventually hope to be able to replace the item.replace(x, y) variables with words in a database.

  • some problem with iOS 4.2.1

    - by bicbac
    Hi, I've been developing an app with MacBook Pro (MBP) so far. Last week one of my friends gave me new macbook air 11"(MBA). so Now I can test my code with more than one machine with the same version of developing tools - Both machine has Xcode (3.2.5) and iOS SDK 4.2.1). After some point my app starts get terminated suddenly(iPhone sumulator), and I was using MBP. I got no error message whatsoever. it just stops. I reckon the crash comes from dealing with memory, like 'release'/ 'double-release'. (I'm not 100% sure though). Anyway I thought there must be some mistake within my code for sure. -Confusion starts from this part.- With my MBA, on the other hand, I don'y see any crash. It just works fine. There is nothing different between MBA & MBP except the h/w specifications. Same code, same versions of XCode and iOS SDK. Is the fact that no crash at MBA suggesting that I have to look somewhere else than the code itself? I red some article and Q&As on iOS4.2.1 and XCode 3.2.5 that the most recent version of XCode doesn't recognize the iOS 4.2.1 since the 4.2.1 came out later the 3.2.5. Is it the reason? I have no idea at this moment what should be the next move. thanks

  • Cost of logic in a query

    - by FrustratedWithFormsDesigner
    I have a query that looks something like this: select xmlelement("rootNode", (case when XH.ID is not null then xmlelement("xhID", XH.ID) else xmlelement("xhID", xmlattributes('true' AS "xsi:nil"), XH.ID) end), (case when XH.SER_NUM is not null then xmlelement("serialNumber", XH.SER_NUM) else xmlelement("serialNumber", xmlattributes('true' AS "xsi:nil"), XH.SER_NUM) end), /*repeat this pattern for many more columns from the same table...*/ FROM XH WHERE XH.ID = 'SOMETHINGOROTHER' It's ugly and I don't like it, and it is also the slowest executing query (there are others of similar form, but much smaller and they aren't causing any major problems - yet). Maintenance is relatively easy as this is mostly a generated query, but my concern now is for performance. I am wondering how much of an overhead there is for all of these case expressions. To see if there was any difference, I wrote another version of this query as: select xmlelement("rootNode", xmlforest(XH.ID, XH.SER_NUM,... (I know that this query does not produce exactly the same, thing, my plan was to move the logic to PL/SQL or XSL) I tried to get execution plans for both versions, but they are the same. I'm guessing that the logic does not get factored into the execution plan. My gut tells me the second version should execute faster, but I'd like some way to prove that (other than writing a PL/SQL test function with timing statements before and after the query and running that code over and over again to get a test sample). Is it possible to get a good idea of how much the case-when will cost? Also, I could write the case-when using the decode function instead. Would that perform better (than case-statements)?

  • waveInProc / Windows audio question...

I'd like to do more with the buffers than simply write to a file, so now I've got a callback set up. It works great and I'm getting the data, but I'm not sure what to do with it once I have it. Here's my callback... everything here works: // Media API callback void CALLBACK AudioRecorder::waveInProc(HWAVEIN hWaveIn, UINT uMsg, DWORD dwInstance, DWORD dwParam1, DWORD dwParam2) { // Data received if (uMsg == WIM_DATA) { // Get wav header LPWAVEHDR mBuffer = (WAVEHDR *)dwParam1; // Now what? for (unsigned i = 0; i != mBuffer->dwBytesRecorded; ++i) { // I can see the char, how do get them into my file and audio buffers? cout << mBuffer->lpData[i] << "\n"; } // Re-use buffer mResultHnd = waveInAddBuffer(hWaveIn, mBuffer, sizeof(mInputBuffer[0])); // mInputBuffer is a const WAVEHDR * } } // waveInOpen cannot use an instance method as its callback, // so we create a static method which calls the instance version void CALLBACK AudioRecorder::staticWaveInProc(HWAVEIN hWaveIn, UINT uMsg, DWORD_PTR dwInstance, DWORD_PTR dwParam1, DWORD_PTR dwParam2) { // Call instance version of method reinterpret_cast<AudioRecorder *>(dwParam1)->waveInProc(hWaveIn, uMsg, dwInstance, dwParam1, dwParam2); } Like I said, it works great, but I'm trying to do the following: Convert the data to short and copy into an array Convert the data to float and copy into an array Copy the data to a larger char array which I'll write into a WAV Relay the data to an arbitrary output device I've worked with FMOD a lot and I'm familiar with interleaving and all that. But FMOD dishes everything out as floats. In this case, I'm going the other way. I guess I'm basically just looking for resources on how to go from LPSTR to short, float, and unsigned char. Thanks much in advance!

  • Domain validates but won't save

    - by marko
    I have the following setup. Class, say, Car that has a CarPart (belongsTo=[car:Car]). When I'm creating a Car I also want to create som default CarParts, so I do def car = new Car(bla bla bla) def part = new CarPart(car:car) Now, when I do car.validate() or part.validate() it seems fine. But when I do if(car.save && part.save() I get this exception: 2012-03-24 14:02:21,943 [http-8080-4] ERROR util.JDBCExceptionReporter - Batch entry 0 insert into car_part (version, car_id, id) values ('0', '297', '298') was aborted.
