  • Visual C# Express 2010: how to set language to C# 2.0

    - by luqui
    I am using Visual C# Express 2010 to develop an application for the Unity3D game engine, which only supports C# 2.0. That is, I am only using it to edit code, but the compilation is done by Unity. I'm wondering if there is a way to configure Visual C# to edit C# 2.0, so that, for example, it yells if I (out of habit) try to use a var declaration or foo => bar function. Thanks!

  • Attempting to calculate width of Map Overlays on the fly

    - by Bloudermilk
    Hey all- I am working on an Android app that utilizes the Google Maps API MapView, MapController, MapActivity, and ItemizedOverlay. I am basically trying to recreate certain functionalities of the Maps app (damn Google for not providing speech bubbles—for lack of a better name—for items!), particularly those speech bubbles. I have an invisible XML structure for the speech bubble in the XML layout file containing my MapView. The first time I show a speech bubble I grab that XML and remove it from it's current parent, applying some ItemizedOverlay.LayoutParams to it, and add it to the MapView as an Overlay. I position it above the item that was selected, fill it with the proper text, then set it to visible. This all works great. The goal here, though, is to also automatically animate the map to reveal any parts of a speech bubble that may be off-screen when it opens. So I'm trying popup.getWidth() (popup is the instance of my LinearLayout that is the speech bubble) after I do all the manipulation to the bubble, even after I display it to the user. Problem is, popup.getWidth() is returning me the width of the previously displayed popup, not the currently displayed one. I can't figure out why this would be happening if I'm fetching the width after I set it to visible with its new dimensions (which, by the way, are relative when I'm setting them with LayoutParams: fill_content for both width and height).. I have even tried forcing both the MapView and the "popup" to invalidate() before trying to fetch the width. Any ideas why this may be happening? How can I force the View to settle into its new dimensions before trying to fetch them? Thanks! Nick

  • Rails: Added new Action in Controller, but there is no path?

    - by Newbie
    Hello! I try to do following: A user is on his profile page. Now he edits his profile. He klicks on update and the data is saved. Now I want to redirect the user to another kind of profile-edit-page. I did the following in my users_controller.rb: def update @user = User.find(params[:id]) respond_to do |format| if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' if(@user.team_id != nil) format.html { redirect_to(@user) } else format.html { redirect_to choose_team_path } end format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end end end def choose_team @user = User.find(params[:id]) end I created a view: /users/choose_team.html.erb Now I get the following error: undefined local variable or method `choose_team_path' for #<UsersController:0x1f56650> So I added choose_team to my routes.rb: map.choose_team 'choose-team', :controller => 'users', :action => 'choose_team' Now, after submitting my first edit form, it redirects me to http://localhost:3000/choose-team and I get following error: Couldn't find User without an ID What I want: If a user has no team_id, he should be redirected to my choose_team.html.erb for choosing a team, else he should be redirected to his profile/show. How to do this?

  • Advanced XPath query

    - by alex
    Hello, I have an XML file that looks like this: <?xml version="1.0" encoding="utf-8" ?> <PrivateSchool> <Teacher id="teacher1"> <Name> teacher1Name </Name> </Teacher> <Teacher id="teacher2"> <Name> teacher2Name </Name> </Teacher> <Student id="student1"> <Name> student1Name </Name> </Student> <Student id="student2"> <Name> student2Name </Name> </Student> <Lesson student="student1" teacher="teacher1" /> <Lesson student="student2" teacher="teacher2" /> <Lesson student="student3" teacher="teacher3" /> <Lesson student="student1" teacher="teacher2" /> <Lesson student="student3" teacher="teacher3" /> <Lesson student="student1" teacher="teacher1" /> <Lesson student="student2" teacher="teacher4" /> <Lesson student="student1" teacher="teacher1" /> </PrivateSchool> There's also a DTD associated with this XML, but I assume it's not much relevant to my question. Let's assume all needed teachers and students are well defined. What is the XPath query that returns the teachers' NAMES, that have at least one student that took more than 10 lessons with them? I was looking at many XPath sites/examples. Nothing seemed advanced enough for this kind of question... Thank you

  • How can I prevent page-break in CFDocument from occuring in middle of content?

    - by Dan Roberts
    I am generating a PDF file dynamically from html/css using the cfdocument tag. There are blocks of content that I don't want to span multiple pages. After some searching I found that the style "page-break-inside" is supported according to the docs. However in my testing the declaration "page-break-inside: avoid" does no good. Any suggestions on getting this style declaration to work, or have alternative suggestions? Here is an example. I would expect the content in the div tag not to span a page break but it does. The style "page-break-inside: avoid" is not being honored. <cfdocument format="flashpaper"> <cfloop from="1" to="10" index="i"> <div style="page-break-inside: avoid"> <h1>Table Label</h1> <table> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> </table> </div> </cfloop> </cfdocument>

  • Can I add a spring mvc filter using jetty with a jar file?

    - by Juan Manuel
    I have a simple web application disguised as a java application (as in, it's a .jar instead of a .war), and I'd like to use a filter for my requests. If it was a .war, I could initialize it with a WebAppContext and specify a web.xml file where I'd have my filter declaration like this <filter> <filter-name>myFilter</filter-name> <filter-class>MyFilterClass</filter-class> </filter> <filter-mapping> <filter-name>myFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> However, I'm using a simple Context to initialize my application with Spring. Server server = new Server(8082); Context root = new Context(server, "/", Context.SESSIONS); DispatcherServlet dispatcherServlet = new DispatcherServlet(); dispatcherServlet.setContextConfigLocation("classpath:application-context.xml"); root.addServlet(new ServletHolder(dispatcherServlet), "/*"); server.start(); Is there a way to programmatically specify filters for the spring servlet, without using a web.xml file?

  • LaTeX - Changing the font sizxe for a document, but in the preamble, not the document class?

    - by Rory
    I have a LaTeX document. I want to change the font size of all the text, to make it smaller. Normally I would just change the documentclass part. However I am generating LaTeX files from another programme, and it is setting the documentclass, I can't change that. However I can put things in the preamble. Is there anyway to change the font size in the preamble, without touching the documentclass declaration.

  • Override generic methods in c#

    - by Pascal
    I thought I can not override generic methods of a derived class. http://my.safaribooksonline.com/book/programming/csharp/9780071741163/generics/ch18lev1sec13 The code in this link runs fine. The overriden method is called although the instance type of the base class is used and not the instance of the derived type. Now I am confused because a former question of mine Type parameter declaration must be identifier not a type is about calling the overriding generic method with the instance of base type which did NOT work!

  • Problem with C function of type char pointer, can someone explain?

    - by JJ
    Find the errors from following C function : char* f(int i) { int i; char buffer[20]; switch ( i ) { 1: strcpy( buffer, "string1"); 2: strcpy( buffer, "string2"); 3: strcpy( buffer, "string3"); default: strcpy(buffer, "defaultstring"); } return buffer; } this is c funtion not C++, I think it has to do with type conversion my compiler give warning that declaration of int i shadows a parameter.

  • shared_ptr as class member

    - by idimba
    It's common to declared contained objects as a pointers to that class, while "forward declarating" them in header file. This in order to reduce physical dependencies in code. For example class B; // forward declaration class A { private: B* pB; }; Would it be good idea to declare such a member as shared_ptr, instead of naked pointer? I would prefer scoped_ptr, but AFAIKit it won't be in standard.

  • What is wrong with this list comprehension code?

    - by suresh
    My aim is to list all elements of the array a whose values are greater than their index positions. I wrote a Haskell code like this. [a|i<-[0..2],a<-[1..3],a!!i>i] When tested on ghci prelude prompt, I get the following error message which I am unable to understand. No instance for (Num [a]) arising from the literal 3 at <interactive>:1:20 Possible fix: add an instance declaration for (Num [a])

I know that I should link the wchar library during compilation, but how do I do that?

  • How to change database connection without compiling, using JBoss Seam?

    - by MLB
    Hi there: I am developing a web site in Eclipse using JBoss Seam 1.2. My site uses a database (named ALregcli) hosted in a MySQL server. That database has only one table named trazasfallos. The server I am using is local (localhost). When I deploy the site in an "X HOST", the MySQL server it is not in the same computer... the server is in an "Y HOST", so, the connection will not be stablished to the database. I was changing the Context.xml, but it didn't work. The only way it worked was changing the host to connect to in the Context.xml and "recompiling" all the project. Then, it generates the new version of the compiled class trazasfallos.class, and this is the file I have to overwrite for connecting to a new database server. The point is that I want to make the change without "recompiling" anything... Maybe there is a way to make only a "text change" and it will work (maybe in a .xml file)... but I don't know how to do it!! The question is: how to change the connection to the database without recompiling anything in the site?? I am sorry about my English, I am from Cuba.

  • SVNKit: How to get the repository url from a local path?

    - by StackedCrooked
    I would like to implement a method that can get the svn revision number from the path where a SVN repository has been checked out. The method declaration would look something like this: long getRevisionNumber(String localPath) { ... } I'm trying to use SVNKit for this, but it seems to require an SVN URL to start with. Is there any way to start with a local path?

  • Grails - Where to store properties related to domains

    - by GalmWing
    This is something I have been struggling about for some time now. The thing is: I have many (20 or so) static arrays of values. I say static because that is how I'm actually storing them, as static arrays inside some domains. For example, if I have a list of known websites, I do: class Website { ... static websites = ["web1", "web2" ...] } But I do this just while developing, because I can easily change the arrays if needed, but what I'm going to do when the application is ready for deployment? In my project it is very probable that, at some point, these arrays of values change. I've been researching on that matter, one can store application properties inside an external .properties file, but it will be impossible to store an array, even futile, because if some array gets an additional value, the application can't recognize it until the name of the new property is added where needed. Another approach is to store this information in the database, but for some reason it seems like a waste to add 20 or more tables that will have just two rows, an id and a name. And the last option, as far as I know, would be an XML, but I'm not very experienced with those. It seems groovy has a way of creating and reading XML files relatively easy, but I don't know how difficult would be to modify an XML whose layout is predefined in the application. Needless to say that storing them in the config.groovy is not an option since any change will require to recompile. I haven't come across some "standard" (maybe a best practice?) way of dealing with these. So the questions is: Where to store these arrays?

  • Eclipse Ant Builder problem

    - by styx777
    I made a custom ant script to automatically create a jar file each time I do a build. This is how it looks like: <?xml version="1.0" encoding="UTF-8"?> <project name="TestProj" basedir="." default="jar"> <property name="dist" value="dist" /> <property name="build" value="bin/test/testproj" /> <target name="jar"> <jar destfile="${dist}/TestProj.jar"> <manifest> <attribute name="Main-Class" value="test.testproj.TestProj" /> </manifest> <fileset dir="${build}" /> </jar> </target> </project> I added it by Right clicking my project properties builders clicked new Ant builder then I specified the location of the above xml file. However, when I run it by doing: java -jar TestProj.jar I get a NoClassDefFoundError test/testproj/TestProj I'm using Eclipse in Ubuntu. TestProj is the name of the class and it's in package test.testproj I'm pretty sure there's something wrong with the manifest and probably the location of the xml file as well but I'm not sure how to fix this. Any ideas?

  • What do I do about a Java program that spawned two instaces of itself?

    - by user288915
    I have a java JAR file that is triggered by a SQL server job. It's been running successfully for months. The process pulls in a structured flat file to a staging database then pushes that data into an XML file. However yesterday the process was triggered twice at the same time. I can tell from a log file that gets created, it looks like the process ran twice simultaneously. This caused a lot of issues and the XML file that it kicked out was malformed and contained duplicate nodes etc. My question is, is this a known issue with Java JVM's spawning multiple instances of itself? Or should I be looking at sql server as the culprit? I'm looking into 'socket locking' or file locking to prevent multiple instances in the future. This is the first instance of this issue that I've ever heard of. More info: The job is scheduled to run every minute. The job triggers a .bat file that contains the java.exe - jar filename.jar The java program runs, scans a directory for a file and then executes a loop to process if the file if it finds one. After it processes the file it runs another loop that kicks out XML messages. I can provide code samples if that would help. Thank you, Kevin

  • How do I copy files into an existing JAR file with Ant?

    - by Blue
    I have a project that needs to access resources within its own JAR file. When I create the JAR file for the project, I would like to copy a directory into that JAR file (I guess the ZIP equivalent would be "adding" the directory to the existing ZIP file). I only want the copy to happen after the JAR has been created (and I obviously don't want the copy to happen if I clean and delete the JAR file). Currently the build file looks like this: <?xml version="1.0" encoding="UTF-8"?> <project name="foobar" basedir=".." default="jar"> <!-- project-specific properties --> <property name="project.path" value="my/project/dir/foobar" /> <patternset id="project.include"> <include name="${project.path}/**" /> </patternset> <patternset id="project.jar.include"> <include name="${project.path}/**" /> </patternset> <import file="common-tasks.xml" /> <property name="jar.file" location="${test.dir}/foobar.jar" /> <property name="manifest.file" location="misc/foobar.manifest" /> </project> Some of the build tasks are called from another file (common-tasks.xml), which I can't display here. Thanks.
