  • Git/SVN for asp.net development instead of VSS?

    - by jrutter
    At work, we are using ASP.net 2.0 and VSS. VSS is a beast, we are continually having issues with people checking out files and there is no branching - makes it crazy. I know SVN/GIT is mainly used by open source developers, are there any downsides to ASP.NET developers using it? I have been pushing for SVN internally, but am thinking GIT might also be a great option. Our team is spread across 3 continents.

  • opengl + glew in Eclipse (for windows)

    - by echo
    I'm trying to get glew to work under eclipse (mingw) in windows. Seems as if it is extremely unusual not to use Visual Studio in this context. The install instructions for glew is simply "use the project file in build/vc6/"... The glew readme also writes: "If you wish to build GLEW from scratch (update the extension data from the net or add your own extension information), you need a Unix environment (including wget, perl, and GNU make). The extension data is regenerated from the top level source directory with: make extensions" In order to get glew to work in eclipse and windows I have to compile it in a unix environment? Is there no other way? Sure, it would probably be a learning experience to pull that off (if I were to succeed) but I feel that my time is best spent actually working on my project. And even if I did manage to crosscompile everything, would it work in anything but Visual Studio? Is the whole thing unfeasible and the best solution is to install Visual Studio? Google haven't been of much help, I feel like I am the only one that has ever attempted to do this (is there a good reason this?).

  • Why do .NET developers offer 32-bit/64-bit versions of .NET assemblies?

    - by Tyler
    Evey now and then I see both x86 and x64 versions of a .NET assembly. Consider the following web part for SharePoint. Why wouldn't the developer just offer a single version and have let the JIT compiler sort out the rest? When I see these kinds offering is it just that the developer decided to create a native image using a tool like ngen in order to avoid a JIT? Someone please help me out here, I feel like I'm missing something of note. Updated From what I got below, both x86 and x64 builds are offered because one or more of the following reasons: The developer wanted to avoid JITing and created a native image of his code, targeting a given architecture using a tool like ngen.exe. The assembly contains platform specific COM calls and so it makes no point to build it as AnyCPU. In these cases builds that target different platforms may contain different code. The assembly may contain Win32 calls using pinvoke which won't get remapped by a JIT and so the build should target the platform it is bound to.

  • Scrum backlog sizing is taking forever

    - by zachary
    I work on a huge project. While we program we end up meeting for endless backlog sizing sessions where all the developers sit down with the team and size user stories. Scrum doubters are saying that this process is taking too long and development time is being wasted. My question is how long should it take to size a user story on average? And does anyone have any tips to make these sizing sessions go quicker?

  • How to disable MSBuild's <RegisterOutput> target on a per-user basis?

    - by Roger Lipscombe
    I like to do my development as a normal (non-Admin) user. Our VS2010 project build fails with "Failed to register output. Please try enabling Per-user Redirection or register the component from a command prompt with elevated permissions." Since I'm not at liberty to change the project file, is there any way that I can add user-specific MSBuild targets or properties that disable this step on a specific machine, or for a specific user? I'd prefer not to hack on the core MSBuild files. I don't want to change the project file because I might then accidentally check it back in. Nor do I want to hack on the MSBuild core files, because they might get overwritten by a service pack. Given that the Visual C++ project files (and associated .targets and .props files) have about a million places to alter the build order and to import arbitrary files, I was hoping for something along those lines. MSBuild imports/evaluates the project file as follows (I've only looked down the branches that interest me): Foo.vcxproj Microsoft.Cpp.Default.props Microsoft.Cpp.props $(UserRootDir)\Microsoft.Cpp.$(Platform).user.props Microsoft.Cpp.targets Microsoft.Cpp.$(Platform).targets ImportBefore\* Microsoft.CppCommon.targets The "RegisterOutput" target is defined in Microsoft.CppCommon.targets. I was hoping to replace this by putting a do-nothing "RegisterOutput" target in $(UserRootDir)\Microsoft.Cpp.$(Platform).user.props, which is %LOCALAPPDATA%\MSBuild\v4.0\Microsoft.Cpp.Win32.user.props (UserRootDir is set in Microsoft.Cpp.Default.props if it's not already set). Unfortunately, MSBuild uses the last-defined target, which means that mine gets overridden by the built-in one. Alternatively, I could attempt to set the %(Link.RegisterOutput) metadata, but I'd have to do that on all Link items. Any idea how to do that, or even if it'll work?

  • Which compiler option I should choose?

    - by Surjya Narayana Padhi
    Hi Geeks, I have to use the third party static library for my qt application to run on windows. The third party provides me a .lib and .h file for use. These libraries are compiled with MSVC compiler. My qt Creator is using MinGW compiler to compile my application. I copied the .h and .lib file to my qt project directory and then added those in .pro file as follows QT += core gui TARGET = MyTest TEMPLATE = app LIBS += C:\Qt\2010.05\qt\MyTest\newApi.lib SOURCES += main.cpp\ mainwindow.cpp HEADERS += mainwindow.h \ newApi.h FORMS += mainwindow.ui Now I am getting some runtime error like this - Starting C:\Qt\2010.05\qt\MyTest-build-desktop\debug\MyTest.exe... C:\Qt\2010.05\qt\MyTest-build-desktop\debug\MyTest.exe exited with code -1073741515 Can any body suggest is this runtime error is due to mismatch of compiler? (because of my .lib file I added is comipled in MSVC compiler and my qt app is compiled using MinGW compiler) If not what may be the reason? Am I missing anything in adding the .h and .lib file to my qt project? If my MinGW compiler will not support the .lib file generated in MSVC compiler what may be the work-arround? Can I create the .lib files in MinGW compiler? or this format is supported only by MSVC compiler only? Please suggest...

  • Are there good reasons not to use an ORM?

    - by hangy
    During my apprenticeship, I have used NHibernate for some smaller projects which I mostly coded and designed on my own. Now, before starting some bigger project, the discussion arose how to design data access and whether or not to use an ORM layer. As I am still in my apprenticeship and still consider myself a beginner in enterprise programming, I did not really try to push in my opinion, which is that using an object relational mapper to the database can ease development quite a lot. The other coders in the development team are much more experienced than me, so I think I will just do what they say. :-) However, I do not completely understand two of the main reasons for not using NHibernate or a similar project: One can just build one’s own data access objects with SQL queries and copy those queries out of Microsoft SQL Server Management Studio. Debugging an ORM can be hard. So, of course I could just build my data access layer with a lot of SELECTs etc, but here I miss the advantage of automatic joins, lazy-loading proxy classes and a lower maintenance effort if a table gets a new column or a column gets renamed. (Updating numerous SELECT, INSERT and UPDATE queries vs. updating the mapping config and possibly refactoring the business classes and DTOs.) Also, using NHibernate you can run into unforeseen problems if you do not know the framework very well. That could be, for example, trusting the Table.hbm.xml where you set a string’s length to be automatically validated. However, I can also imagine similar bugs in a “simple” SqlConnection query based data access layer. Finally, are those arguments mentioned above really a good reason not to utilise an ORM for a non-trivial database based enterprise application? Are there probably other arguments they/I might have missed? (I should probably add that I think this is like the first “big” .NET/C# based application which will require teamwork. Good practices, which are seen as pretty normal on Stack Overflow, such as unit testing or continuous integration, are non-existing here up to now.)

  • How do I return the value of the owner and id attributes respectively from an XML result set using P

    - by pharma_joe
    I am using PHP to iterate over the following result set, the aim is to build a hyperlink for each result using a foreach loop. I have stored the XML result in $images, and have constructed this loop: foreach ($images as $image) { //Build link to each photo returned //base URL $flickrPhotoUrl = 'http://www.flickr.com/photos/'; //Append user ID $flickrPhotoUrl .= ""; echo $flickrPhotoUrl; } Here is a sample result from Flickr: <photos page="1" pages="10982" perpage="10" total="109813"> <photo id="4616840471" owner="47823583@N03" secret="1b83173bc0" server="4013" farm="5" title="Strawberry Bears" ispublic="1" isfriend="0" isfamily="0"></photo> <photo id="4616612597" owner="12658756@N08" secret="f626214382" server="4059" farm="5" title="Yarn Chef Minestrone - Grickle Grass" ispublic="1" isfriend="0" isfamily="0"></photo> <photo id="4616469567" owner="26284268@N00" secret="6911a66838" server="4022" farm="5" title="P5130121.JPG" ispublic="1" isfriend="0" isfamily="0"></photo> <photo id="4617076736" owner="26284268@N00" secret="8b990acba4" server="4047" farm="5" title="P5130106.JPG" ispublic="1" isfriend="0" isfamily="0"></photo> <photo id="4616470013" owner="26284268@N00" secret="44600b3836" server="4036" farm="5" title="P5130125.JPG" ispublic="1" isfriend="0" isfamily="0"></photo> <photo id="4616466147" owner="26284268@N00" secret="554eab8667" server="4052" farm="5" title="P5130116.JPG" ispublic="1" isfriend="0" isfamily="0"></photo> <photo id="4617082398" owner="26284268@N00" secret="4a2b663442" server="3350" farm="4" title="P5130118.JPG" ispublic="1" isfriend="0" isfamily="0"></photo> <photo id="4617078272" owner="26284268@N00" secret="357737017b" server="4013" farm="5" title="P5130109.JPG" ispublic="1" isfriend="0" isfamily="0"></photo> <photo id="4617081446" owner="26284268@N00" secret="1f87726497" server="4048" farm="5" title="P5130117.JPG" ispublic="1" isfriend="0" isfamily="0"></photo> <photo id="4617077676" owner="26284268@N00" secret="77ca9f754a" server="3330" farm="4" title="P5130108.JPG" ispublic="1" isfriend="0" isfamily="0"></photo>

  • Host WCF in MVC2 Site

    - by Basiclife
    Hi, We've got a very large, complex MVC2 website. We want to add an API for some internal tools and decided to use WCF. Ideally, we want MVC itself to host the WCF service. Reasons include: Although there's multiple tiers to the application, some functionality we'd like in the API requires the website itself (e.g. formatting emails). We use TFS to auto-build (continuous integration) and deploy - The less we need to modify the build and release mechanism the better We use the Unity container and Inversion of Control throughout the application. Being part of the Website would allow us to re-use configuration classes and other helper methods. I've written a custom ServiceBehavior which in turn has a custom InstanceProvider - This allows me to instantiate and configure a container which is then used to service all requests for class instances from WCF. So my question is; Is it possible to host a WCF service from within MVC itself? I've only had experience in Services / Standard Asp.Net websites before and didn't realise MVC2 might be different until I actually tried to wire it into the config and nothing happened. After some googling, there don't seem to be many references to doing this - so thought I'd ask here.

  • Google Maps API - Marker not showing

    - by popnbrown
    I'm trying to add markers for every single row from a table, that sits on the page. The page is http://www.sravanks.com/first/2013ftcmap.php This is the JS code that's loading the markers: $(document).ready(function() { var mapOptions = { center: new google.maps.LatLng(39.740, -89.503), zoom: 7 }; var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions); var infowindow = new google.maps.InfoWindow(); /* City Markers */ var cityCircle = new Array(); var i = 0; $.each($('.events tr'), function(index, value) { var name = $(this).find('td:first()').html(); var address = $(this).find('.address').html(); var linkUrl = "http://www.sravanks.com/first/geocode.php?address=" + address; $.ajax({ url: linkUrl }).done(function(data){ var json = $.parseJSON(data.substring(0, data.length-1)); lat = json.results[0].geometry.location.lat; lng = json.results[0].geometry.location.lng; var latlng = new google.maps.LatLng(lat, lng); var marker = new google.maps.Marker({ position: latlng, map: map, icon: 'map-pointer-medium.gif' }); google.maps.event.addListener(marker, 'click', function() { infowindow.setContent(name); infowindow.open(map, marker); cityCircle[i] = new google.maps.Circle({strokeColor: '#00FF00', strokeOpacity: 0.8, strokeWeight: 2, fillColor: '#00FF00', fillOpacity: 0.35, map: map, center: latlng, radius: 144841}); i++; }); }); }); /*Team Markers*/ var markers = {}; var teamName, teamNumber, lat, lng, content; $.each($('.list tr'), function(index, value) { teamName = $(this).find('td.name').html(); teamNumber = $(this).find('td.number').html(); markers[teamNumber] = {}; lat = parseFloat($(this).find('td.lat').html()); lng = parseFloat($(this).find('td.lng').html()); content = "Name: " + teamName + "<br />Number: " + teamNumber; markers[teamNumber]['latlng'] = new google.maps.LatLng(lat, lng); markers[teamNumber]['marker'] = new google.maps.Marker({ position: markers[teamNumber]['latlng'], map: map }); google.maps.event.addListener(markers[teamNumber]['marker'], 'click', function() { infowindow.setContent(content); infowindow.open(map, markers[teamNumber]['marker']); }); }); google.maps.event.addListener(infowindow, 'closeclick', function() { for(var i=0;i<cityCircle.length;i++){ cityCircle[i].setMap(null); } }); }); I've got no errors, but the Team Markers do not show up. The strange thing is that the City Markers do show up. Some more info, the City Markers ajax call is just to a proxy that calls the google geocoding api. Again the link's at http://www.sravanks.com/first/2013ftcmap.php

  • How to deploy a single webapp with multiple web-modules that may be removed or added individually

    - by Daniel Bleisteiner
    We currently run two separate webapps (WARs) deployed in one single EAR containing additional JARs and settings. To improve our deployment I want to split one of these webapps into different modules that may be build and packaged individually. But I've currently no clue on how to package these modules so that I'm able to add or remove them as desired - at best during runtime. The webapp is getting more and more complex and I'd like to separate some of the functionality into modules. These modules should be packaged as single archives. As long as they contain only classes and resources loaded through code I know how to do this (simple JARs). But how about JSPs? Normally a WAR file contains JSPs or HTML files. I my case it are JSF pages utilizing JBoss Seam and RichFaces. These modules will add classes, resources and JSF pages and other includes to the running webapplication. Is it somehow possible to deploy them as individual archives to serve the same running webapp? We are using Maven for our build and packaging and deploy into JBoss v4.

  • How can I spec out an authlogic sessions controller using using a stub?

    - by Dave
    I want to test my User Session Controller testing that a user session is first built then saved. My UserSession class looks like this: class UserSession < Authlogic::Session::Base end The create method of my UserSessionsController looks like this: def create @user_session = UserSession.new(params[:user_session]) if @user_session.save flash[:notice] = "Successfully logged in." redirect_back_or_default administer_home_page_url else render :new end end and my controller spec looks like this: describe UserSessionsController do it "should build a new user session" do UserSession.stub!(:new).with(:email, :password) UserSession.should_receive(:new).with(:email => "[email protected]", :password => "foobar") post :create, :user_session => { :email => "[email protected]", :password => "foobar" } end end I stub out the new method but I still get the following error when I run the test: Spec::Mocks::MockExpectationError in 'UserSessionsController should build a new user session' <UserSession (class)> received :new with unexpected arguments expected: ({:password=>"foobar", :email=>"[email protected]"}) got: ({:priority_record=>nil}, nil) It's although the new method is being called on UserSession before my controller code is getting called. Calling activate_authlogic makes no difference.

  • How to automate detection of out of order tab navigation in Qt dialogs?

    - by WilliamKF
    Typically, a dialog wishes to have tab navigation proceed in an orderly fashion through a dialog that roughly corresponds to the order of reading a book. When new fields are added to a dialog by engineers on a team, the new widgets can often not be inserted in tab correct order. Can anyone think of a way to automate the detection of out of tab navigation order widgets within a dialog?

  • Possible to Dynamic Form Generation Using PHP global variables

    - by J M 4
    I am currently a fairly new programmer but am trying to build a registration page for a medical insurance idea we have which captures individual information and subsequent pieces of information about that individual's sub parts. In this case, it is a fight promoter enrolling his 15+ boxers for fight testing services. Right now, I have the site fully laid out to accept 7 fighters worth of information. This is collected during the manager's enrollment. However, each fighter's information is passed and stored in session super globals such as: $_SESSION['F1Firstname']; and $_SESSION['F3SSN3'];. The issue I am running into is this, I want to create a drop down menu selector for the manager to add information for up to 20-30 fighters. Right now I use PHP to state: if ($_SESSION['Num_Fighters'] 6) ... then display the table form fields to collect consumer data. If I have to build hidden elements for 30 fighters AND provide javascript/php validation (yes I am doing both) then I fear the file size for the document will be unnecessarily large for the maanger who only wants to enroll 2 fighters. Can anybody help?

  • Decent profiler for Windows?

    - by olliej
    Does windows have any decent sampling (eg. non-instrumenting) profilers available? Preferably something akin to Shark on MacOS, although i am willing to accept that i am going to have to pay for such a profiler on windows. I've tried the profiler in VS Team Suite and was not overly impressed, and was wondering if there were any other good ones. [Edit: Erk, i forgot to say this is for C/C++, rather than .NET -- sorry for any confusion]

  • What is the technical skill degree of your co-workers?

    - by bonefisher
    For now it has been around 4 years that I work as developer. Most of my team mates, from their tech-skill, programming ability and code practices view, are somewhere between junior and senior. In all my previous jobs, there was a real geek who was brilliant at coding/analyzing/lead, but the others were just 'average' programmers. How would you rank your co-workers as good developers from rank 1 (best) - 5 (worst) ?

  • How do I enforce the order of qmake library dependencies?

    - by James Oltmans
    I'm getting a lot of errors because qmake is improperly ordering the boost libraries I'm using. Here's what .pro file looks like QT += core gui TARGET = MyTarget TEMPLATE = app CONFIG += no_keywords \ link_pkgconfig SOURCES += file1.cpp \ file2.cpp \ file3.cpp PKGCONFIG += my_package \ sqlite3 LIBS += -lsqlite3 \ -lboost_signals \ -lboost_date_time HEADERS += file1.h\ file2.h\ file3.h FORMS += mainwindow.ui RESOURCES += Resources/resources.qrc This produces the following command: g++ -Wl,-O1 -o MyTarget file1.o file2.o file3.o moc_mainwindow.o -L/usr/lib/x86_64-linux-gnu -lboost_signals -lboost_date_time -L/usr/local/lib -lmylib1 -lmylib2 -lsqlite3 -lQtGui -lQtCore Note: mylib1 and mylib2 are statically compiled by another project, placed in /usr/local/lib with an appropriate pkg-config .pc file pointing there. The .pro file references them via my_package in PKGCONFIG. The problem is not with pkg-config's output but with Qt's ordering. Here's the .pc file: prefix=/usr/local exec_prefix=${prefix} libdir=${exec_prefix}/lib includedir=${prefix}/include Name: my_package Description: My component package Version: 0.1 URL: http://example.com Libs: -L${libdir} -lmylib1 -lmylib2 Cflags: -I${includedir}/my_package/ The linking stage fails spectacularly as mylib1 and mylib2 come up with a lot of undefined references to boost libraries that both the app and mylib1 and mylib2 are using. We have another build method using scons and it properly orders things for the linker. It's build command order is below. g++ -o MyTarget file1.o file2.o file3.o moc_mainwindow.o -L/usr/local/lib -lmylib1 -lmylib2 -lsqlite3 -lboost_signals -lboost_date_time -lQtGui -lQtCore Note that the principle difference is the order of the boost libs. Scons puts them at the end just before QtGui and QtCore while qmake puts them first. The other differences in the compile commands are unimportant as I have hand modified the qmake produced make file and the simple reordering fixed the problem. So my question is, how do I enforce the right order in my .pro file despite what qmake thinks they should be?

  • Getting a gestureoverlayview

    - by Codejoy
    I have been using some nice tutorials on drawing graphics on my android. I wanted to also add in the cool gesture demo found here: http://developer.android.com/resources/articles/gestures.html That takes these lines of code: GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures); gestures.addOnGesturePerformedListener(this); This is fine and dandy yet I realize in my demo i'm trying to build using code from "Playing with Graphics in Android". The demos make sense, everything makes sense but I found out by using: setContentView(new Panel(this)); as is required by the Playing With Graphics tutorials, then the findViewById seems to no longer be valid and returns null. At first I was about to post a stupider question as to why this is happening, a quick test of playing with the setContentView made me realize the cause of findViewById returning null, I just do not know how to remedy this issue. Whats the key I am missing here? I realize that the new Panel is doinking some reference up but I am not sure how to make the connection here. The: R.id.gestures is defined right int he main.xml as: (just like the tutorial) <android.gesture.GestureOverlayView android:id="@+id/gestures" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1.0" /> So I did confirm the setContentView(new Panel(this)) is causing the issue. So I know the issue is that I have to figure out how to add the android.gesture.GestureOverlayView to the panel class somehow, I am just not sure how to go about this. After fighting with this I generally know what I need to do just now how to do it. I think I need either the equivalent of creating a panel in that main.xml OR figuring out how to build whats in main.xml for the gestures in code. I am close because I did this: GestureOverlayView gestures = new GestureOverlayView(this); which gets me a non null gestures now, unfortunately since I am not telling it to fill Parent anywhere I don't think its really showing up, so I am trying hard to figure out layout pa rams. Am I even on the right track?

  • Spring Data Neo4J @Indexed(unique = true) not working

    - by Markus Lamm
    I'm new to Neo4J and I have, probably an easy question. There're NodeEntitys in my application, a property (name) is annotated with @Indexed(unique = true) to achieve the uniqueness like I do in JPA with @Column(unique = true). My problem is, that when I persist an entity with a name that already exists in my graph, it works fine anyway. But I expected some kind of exception here...?! Here' s an overview over basic my code: @NodeEntity public abstract class BaseEntity implements Identifiable { @GraphId private Long entityId; ... } public class Role extends BaseEntity { @Indexed(unique = true) private String name; ... } public interface RoleRepository extends GraphRepository<Role> { Role findByName(String name); } @Service public class RoleServiceImpl extends BaseEntityServiceImpl<Role> implements { private RoleRepository repository; @Override @Transactional public T save(final T entity) { return getRepository().save(entity); } } And this is my test: @Test public void testNameUniqueIndex() { final List<Role> roles = Lists.newLinkedList(service.findAll()); final String existingName = roles.get(0).getName(); Role newRole = new Role.Builder(existingName).build(); newRole = service.save(newRole); } That's the point where I expect something to go wrong! How can I ensure the uniqueness of a property, without checking it for myself?? THANKS IN ADVANCE FOR ANY IDEAS!! P.S.: I'm using neo4j 1.8.M07, spring-data-neo4j 2.1.0.BUILD-SNAPSHOT and Spring 3.1.2.RELEASE.
