  • Problems upgrading VB.Net 2008 project into VS2010

    - by Brett Rigby
    Hi there, I have been upgrading several different VS2008 projects into VS2010 and have found a problem with VB.Net projects when they are converted. Once converted, the .vbproj files have changed from this in VS2008: <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' "> <DebugSymbols>true</DebugSymbols> <DebugType>full</DebugType> <DefineDebug>true</DefineDebug> <DefineTrace>true</DefineTrace> <OutputPath>bin\Debug\</OutputPath> <DocumentationFile>CustomerManager.xml</DocumentationFile> <WarningsAsErrors>41999,42016,42017,42018,42019,42020,42021,42022,42032,42036</WarningsAsErrors> </PropertyGroup> To this in VS2010: <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' "> <DebugSymbols>true</DebugSymbols> <DebugType>full</DebugType> <DefineDebug>true</DefineDebug> <DefineTrace>true</DefineTrace> <OutputPath>bin\Debug\</OutputPath> <DocumentationFile>CustomerManager.xml</DocumentationFile> <NoWarn>42353,42354,42355</NoWarn> <WarningsAsErrors>41999,42016,42017,42018,42019,42020,42021,42022,42032,42036</WarningsAsErrors> </PropertyGroup> The main difference, is that in the VS2010 version, the 42353,42354,42355 value has been added; Inside the IDE, this manifests itself as the following setting in the Project Properties | Compile section as: "Function returning intrinsic value type without return value" = None This isn't a problem when building code inside Visual Studio 2010, but when trying to build the code through our continuous integration scripts, it fails with the following errors: [msbuild] vbc : Command line error BC2026: warning number '42353' for the option 'nowarn' is either not configurable or not valid [msbuild] vbc : Command line error BC2026: warning number '42354' for the option 'nowarn' is either not configurable or not valid [msbuild] vbc : Command line error BC2026: warning number '42355' for the option 'nowarn' is either not configurable or not valid I couldn't find anything on Google for these messages, which is strange, as I am trying to find out why this is happening. Any suggestions as to why Visual Studio 2010's conversion wizard is doing this?

  • Stack overflow in compojure web project

    - by Anders Rune Jensen
    Hi I've been playing around with clojure and have been using it to build a simple little audio player. The strange thing is that sometimes, maybe one out of twenty, when contacting the server I will get the following error: 2010-04-20 15:33:20.963::WARN: Error for /control java.lang.StackOverflowError at clojure.lang.RT.seq(RT.java:440) at clojure.core$seq__4245.invoke(core.clj:105) at clojure.core$filter__5084$fn__5086.invoke(core.clj:1794) at clojure.lang.LazySeq.sval(LazySeq.java:42) at clojure.lang.LazySeq.seq(LazySeq.java:56) at clojure.lang.RT.seq(RT.java:440) at clojure.core$seq__4245.invoke(core.clj:105) at clojure.core$filter__5084$fn__5086.invoke(core.clj:1794) at clojure.lang.LazySeq.sval(LazySeq.java:42) at clojure.lang.LazySeq.seq(LazySeq.java:56) at clojure.lang.RT.seq(RT.java:440) at clojure.core$seq__4245.invoke(core.clj:105) at clojure.core$filter__5084$fn__5086.invoke(core.clj:1794) at clojure.lang.LazySeq.sval(LazySeq.java:42) at clojure.lang.LazySeq.seq(LazySeq.java:56) at clojure.lang.RT.seq(RT.java:440) at clojure.core$seq__4245.invoke(core.clj:105) at clojure.core$filter__5084$fn__5086.invoke(core.clj:1794) at clojure.lang.LazySeq.sval(LazySeq.java:42) at clojure.lang.LazySeq.seq(LazySeq.java:56) at clojure.lang.RT.seq(RT.java:440) ... If I do it right after again it always works. So it appears to be related to timing or something. The code in question is: (defn add-track [t] (common/ref-add tracks t)) (defn add-collection [coll] (doseq [track coll] (add-track track))) and (defn ref-add [ref value] (dosync (ref-set ref (conj @ref value)))) where coll is extracted from this function: (defn tracks-by-album [album] (sort sort-tracks (filter #(= (:album %) album) @tracks))) which uses: (defn get-album-from-track [track] (seq/find-first #(= (:album track) (:name %)) @albums)) (defn sort-tracks [track1 track2] (cond (= (:album track1) (:album track2)) (cond (and (:album-track track1) (:album-track track2)) (< (:album-track track1) (:album-track track2)) :else 0) :else (> (:year (get-album-from-track track1)) (:year (get-album-from-track track2))))) it gets called more or less directly from the request I get in: (when-handle-command cmd params (audio/tracks-by-album decoded-name)) (defn when-handle-command [cmd params data] (println (str "handling command:" cmd)) ....) I never get the handling command in my log, so it must die when it does the tracks-by-album. so it does appear to be the tracks-by-album function from the stack trace. I just don't see why it sometimes works and sometimes doesn't. I say that it's tracks-by-album because it's the only function (including it's children) that does filter, as can be seen in the trace. All the source code is available at: http://code.google.com/p/mucomp/. It's my little hobby project to learn clojure and so far it's quite buggy (this is just one bug :)) so I havn't really liked to tell too many people about it yet :)

  • How to setup an hibernate project using annotations compliant with JPA2.0

    - by phmr
    I would like to setup an hibernate project, for this I use the lastest hibernate 3.5-Final. BTW my IDE is Netbeans. The problem is that each time a run the application, it seems to start from a fresh database whatever db backend I use (I tried hsqldb & sqlite): here is my persistence.xml <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="PMMPU" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <class>model.Extrait</class> <class>model.Mot</class> <class>model.Prefixe</class> <class>model.Suffixe</class> <class>model.Texte</class> <properties> <property name="hibernate.dialect" value="dialect.SQLiteDialect"/> <property name="hibernate.connection.username" value=""/> <property name="hibernate.connection.driver_class" value="org.sqlite.JDBC"/> <property name="hibernate.connection.password" value=""/> <property name="hibernate.connection.url" value="jdbc:sqlite:test.db"/> <property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/> <property name="hibernate.hbm2ddl.auto" value="update"/> </properties> </persistence-unit> </persistence> I tried to change hibernate.hbm2ddl.auto value. I got a HibernateUtil class which takes care of creating the emf & em: public class HibernateUtil { private static EntityManagerFactory emf = null; private static EntityManager em = null; public static EntityManagerFactory getEmf() { if(emf == null) emf = Persistence.createEntityManagerFactory("PMMPU"); return emf; } public static EntityManager getEm() { if(em == null) em = getEmf().createEntityManager(); return em; } What did a I do wrong ? edit1: further research with mysql lead me to think that the problem is related to sqlite & hsqldb interaction with hibernate 3.5

  • What is the best way to documentate a system metaphor?

    - by SDReyes
    A metaphor help us to communicate with our project stakeholders, using a shared set of concepts and analogies. we develop them all the time, in one way or another. even the XP- programming highly recommend to get it defined since project start. How do you write such thing down in a document (specially if it already exists)? maybe a dictionary-like approach?

  • FileFinder using SQL

    - by James Morgan
    I was thinking of working on a project while I have some free time and this one looks pretty nice: http://mindprod.com/project/filefinder.html One thing I'm wondering about is that will it really be much faster compared to the regular windows search if I use SQL? I'm planning to use MySQL since it's open source. Also, do I need to be good at databases for this? I have basic knowledge about relational databases and can definitely make some SQL statements. Thanks.

  • MPXJ - get ResourceAssignment baseline values

    - by patmortech
    I'm trying to display the Baseline Start, Finish, Cost, and Work values for a ResourceAssignment, but cannot seem to find any methods on the ResourceAssignment object that would provide this information. Anybody know if this is possible? I know the information is stored because I can see it in MS Project, and I can see it in the XML version of the project file. Just can't see in the API where to get access to it.

  • Cube project doesn't work because of permissions

    I'm doing "Multidimensional Project" with MS SQL Server 2012 (Server Data Tools - Visual Studio 2010 Shell). I can't run (debug) it. If the data source's impersonation information is set to "use the service account", this error occures: Error 2 Internal error: The operation terminated unsuccessfully. 0 0 Error 3 OLE DB error: OLE DB or ODBC error: Login failed for user 'NT Service\MSSQLServerOLAPService'.; 28000. 0 0 Error 4 Errors in the high-level relational engine.

  • Good source for studying professional software development with Visual Studio 2010?

    - by Ben
    I spent a lot of time reading blogs and tutorials on the Net regarding how to do this and that with VS2010, but I thought it would be better to learn it in a more systematic way. Do you know of a good website/book that will teach me how to use Visual Studio 2010/2008 Team System + Microsoft Project to perform various tasks from Project Management to code development and testing in the way the software was designed for? Thank you.

  • Profile memory-performance for part of an rails project

    - by Florian Pilz
    I want to test the profile usage of an important library-class of my rails-project. It uses ActiveRecord so I need all rails dependencies to profile it. As far as I know, I need a patched ruby (rubygc) so script/profile and script/benchmark can track memory usage. I tried to follow this official guide to patch the source code of ruby 1.8.6 (p399) and 1.8.7 (p248), but both fail with the following message: patching file gc.c Hunk #2 succeeded at 50 with fuzz 2 (offset 2 lines). Hunk #3 succeeded at 87 with fuzz 2 (offset 6 lines). Hunk #4 succeeded at 153 with fuzz 1 (offset 45 lines). Hunk #5 succeeded at 409 with fuzz 2 (offset 274 lines). Hunk #6 FAILED at 462. Hunk #7 FAILED at 506. Hunk #8 FAILED at 520. Hunk #9 FAILED at 745. Hunk #10 FAILED at 754. Hunk #11 FAILED at 923. Hunk #12 succeeded at 711 (offset 46 lines).

I also tried to use ruby-prof, but I always get the error "uninitialized constant RubyProf::Test". I don't know how to use the gem "memory" and neither "memprof" nor "bleak_house" could be installed successfully. If I get a patched ruby running, I should be fine. But any other possibility to profile the memory of library classes are welcome. Thanks for helping!

  • executing a script from maven inside a multi module project

    Hi everyone. I have this multi-module project. In the beginning of each build I would like to run some bat file. So i did the following: <profile> <id>deploy-db</id> <build> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.1.1</version> </plugin> </plugins> <pluginManagement> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.1.1</version> <executions> <execution> <phase>validate</phase> <goals> <goal>exec</goal> </goals> <inherited>false</inherited> </execution> </executions> <configuration> <executable>../database/schemas/import_databases.bat</executable> </configuration> </plugin> </plugins> </pluginManagement> </build> </profile> when i run the mvn verify -Pdeploy-db from the root I get this script executed over and over again in each of my modules. I want it to be executed only once, in the root module. What is there that I am missing ? Thanks

  • Function Point Analysis -- a seriously over-estimating technique?

    - by kizzx2
    I know questions about FPA has been asked numerous times before, but this time I'm taking a more analytical angle at it, backed up with data. 1. First, some data This question is based on a tutorial. He had a "Sample Count" section where he demonstrated it step by step. You can see some screenshots of his sample application here. In the end, he calculated the unadjusted FP to be 99. There is another article on InformIT with industry data on typical hour/FP. It ranges from 2 hours/FP to 27.4 hours/FP. Let's try to stick with 2 for the moment (since SO readers are probably the more efficient crowd :p). 2. Reality check!? Now just check out the screenshots again. Do a little math here 99 * 2 = 198 hours 198 hours / 40 hours per week = 5 weeks Seriously? That sample application is going to take 5 weeks to implement? Is it just my feeling that it wouldn't take any decent programmer longer than one week to have it completed? Now let's try estimating the cost of the project. We'll use New York's minimum wage at the moment (Wikipedia), which is $7.25 198 * 7.25 = $1435.5 From what I could see from the screenshots, this application is a small excel-improvement app. I could have bought MS Office Pro for 200 bucks which gives me greater interoperability (.xls files) and flexibility (spreadsheets). (For the record, that same Web site has another article discussing productivity. It seems like they typically use 4.2 hours/FP, which gives us even more shocking stats: 99 * 4.2 = 415 hours = 10 weeks = almost 3 whopping months! 415 hours * $7.25 = $3000 zomg (That's even assuming that all our poor coders get the minimum wage!) 3. Am I missing something here? Right now, I could come up with several possible explanation: FPA is really only suited for bigger projects (1000+ FPs) so it becomes extremely inaccurate at smaller scale. The hours/FP metric fluctuates abruptly from team to team, project to project. For a small project like this, we could have used something like 0.5 hour/FP or something. (Now this kind of makes the whole estimation thing pointless, unless my firm does the same type of projects for several years with the same team, not really common.) From my experience with several software metrics, Function Point is really not a lightweight metric. If the hour/FP thing fluctuates so much, then what's the point, maybe I could have gone with User Story Points which is a lot faster to get and arguably almost as uncertain. What would be the FP experts' answers to this?

  • Dealing with personal failure

    - by codeelegance
    A while ago I was given the task of updating and extending the functionality of a software project. I was given a year to make the needed changes working solo. A month into development I came to the conclusion that it would take longer to change the existing product than to rewrite it from the ground up. I'd never attempted a complete rewrite so I talked with my boss about it and he was thrilled with the idea. I'm a fan of agile development but had never had the opportunity to take advantage of all of the prescribed practices so when I set to work I tried to incorporate as many as I could. I didn't have direct access to the customer and my coworkers (non-programmers) knew the business domain but were already so busy they didn't really have time to participate in design meetings so I resigned to working in the dark and occasionally calling one of them over to my desk to get feedback on my progress. I used TDD and refactored mercilessly and even tried taking a domain driven design approach. Things went well for a while. As the deadline came closer and the complexity of the project grew my productivity start slipping. I found myself cutting corners and ignoring the practices I had established as the pressure increased to meet the deadline. I also started working late nights and weekends to keep up with the load. In the end it made little difference how hard I worked. The project missed its deadline and what was completed wasn't enough to give to the customer. I had failed. Not only had I not finished on time but the previous version had sat untouched for almost a year so it wouldn't be of any help. Luckily we had another product that offered some of the same functionality. My boss decided to cancel the project entirely and moved all our orphaned customers to the other product. I spent weeks (along with everyone else at the company) manning the phones providing technical support for those customers. After it was all over, my boss was gracious enough not to fire me for nearly ruining the company. I was moved to the other product and have been trying to redeem myself ever since. Where did I go wrong? Has anyone else had to deal with this kind of defeat? How did you recover?

  • Error when deploying site of a maven multi module project with FTP

    - by julien
    I have a multi module project. When I launch mvn site:deploy, the deployment of the base module works fine, but it fails to create the directory of the module sites on the FTP server: [INFO] Error uploading site Embedded error: Required directory: '/myremoteftprepository/myproject-mymodule' is missing When I create the missing directory by hand, it works fine, but I would like to avoid that. It is surprising that the deploy command do not create it. Do you how to force this directory creation? Is it a bug in the wagon-ftp plugin? FYI, here is my POM: <build> <extensions> <!-- Enabling the use of FTP --> <extension> <groupId>org.apache.maven.wagon</groupId> <artifactId>wagon-ftp</artifactId> <version>1.0</version> </extension> </extensions> </build> I have chosen to include the javadoc with: <reporting> <plugins> <!-- include javadoc in the site --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <version>2.8</version> <configuration> <show>public</show> </configuration> </plugin> </plugins> </reporting> and <distributionManagement> <site> <id>site</id> <name>maven site</name> <url>ftp://ftp.blabla.org/myremoteftprepository</url> </site> </distributionManagement> and my settings.xml is good.

  • Find completely commented files which are commented by /* */.

    - by Dave
    Similar to this question. I would like to find all commented files. But in my case /* */ is a possibility. Apparently when you write changes to a database project, dropped objects are only commented out instead of deleting the file. I would like to remove all of these commented out files from the project. Is is possible to find all files which start with /* and end with */?

  • How do you handle large projects?

    - by cam
    I've just inherited a large project previously coded by about 4-5 people. The documentation consists of comments, and is not very well written. I have to get up to date on this project. How do I start? It consists of many different source files. Do you just dig in? Are there tools that can help visualize the structure/flow?

  • Java projects without swing

    - by Jeff Home
    I'm quite familiar with Java and I would like to work on a project on my free time but for some reason, I just hate having to work with swing. I'm wondering what kind of Java technologies are available out there that I can use for starting a project. Thank you.

  • Java Sorting "queue" list based on DateTime and Z Position (part of school project)

    - by Kuchinawa
    For a school project i have a list of 50k containers that arrive on a boat. These containers need to be sorted in a list in such a way that the earliest departure DateTimes are at the top and the containers above those above them. This list then gets used for a crane that picks them up in order. I started out with 2 Collection.sort() methods: 1st one to get them in the right XYZ order Collections.sort(containers, new Comparator<ContainerData>() { @Override public int compare(ContainerData contData1, ContainerData contData2) { return positionSort(contData1.getLocation(),contData2.getLocation()); } }); Then another one to reorder the dates while keeping the position in mind: Collections.sort(containers, new Comparator<ContainerData>() { @Override public int compare(ContainerData contData1, ContainerData contData2) { int c = contData1.getLeaveDateTimeFrom().compareTo(contData2.getLeaveDateTimeFrom()); int p = positionSort2(contData1.getLocation(), contData2.getLocation()); if(p != 0) c = p; return c; } }); But i never got this method to work.. What i got working now is rather quick and dirty and takes a long time to process (50seconds for all 50k): First a sort on DateTime: Collections.sort(containers, new Comparator<ContainerData>() { @Override public int compare(ContainerData contData1, ContainerData contData2) { return contData1.getLeaveDateTimeFrom().compareTo(contData2.getLeaveDateTimeFrom()); } }); Then a correction function that bumps top containers up: containers = stackCorrection(containers); private static List<ContainerData> stackCorrection(List<ContainerData> sortedContainerList) { for(int i = 0; i < sortedContainerList.size(); i++) { ContainerData current = sortedContainerList.get(i); // 5 = Max Stack (0 index) if(current.getLocation().getZ() < 5) { //Loop through possible containers above current for(int j = 5; j > current.getLocation().getZ(); --j) { //Search for container above for(int k = i + 1; k < sortedContainerList.size(); ++k) if(sortedContainerList.get(k).getLocation().getX() == current.getLocation().getX()) { if(sortedContainerList.get(k).getLocation().getY() == current.getLocation().getY()) { if(sortedContainerList.get(k).getLocation().getZ() == j) { //Found -> move container above current sortedContainerList.add(i, sortedContainerList.remove(k)); k = sortedContainerList.size(); i++; } } } } } } return sortedContainerList; } I would like to implement this in a better/faster way. So any hints are appreciated. :)

  • What is a name for a job where you do system analysis, project management and data diagramming?

    - by David Archer
    In the last 4 months I've been able to manage a team and step away from the coding for a bit. I've been planning the system in full (both System Analysis and project managing, alongside action and data diagramming) writing the technical documentation, the code's architecture, keeping track of the other guys doing the actual coding, QA, bug reports and dealing with clients. I had to take two days' training on node.js just to see if it would be suitable for a project we were considering. Is there a name for this job? Project Manager and Systems Architect don't quite seem to have the same stuff, and IT manager seems way off. I only want to know so that I can get some qualification towards it and try to move into this kind of work full-time.
