  • Is it possible to access a running instance of an app using JNA/JNI?

    - by Carlos Blanco
    I'm writing a test engine for a Java application that has some of the code written in C. This application uses JNI to access it's native part. In the engine I'm writing, I use Fest to control de UI and perform the tests. However, I,m blind when dealing with the part that is written in C. I wonder if I can use JNA or JNI to access the native part of the app. I believe that the fact that the application is already running is huge issue here.

  • Is it possible to call a procedure within an SQL statement?

    - by darren
    Hi everyone I thought I would use a stored routine to clean up some of my more complex SQL statements. From what I've read, it seems impossible to use a stored procedure within an sql statement, and a stored function only returns a single value when what I need is a result set. I am using mySQL v5.0 SELECT p.`id`, gi.`id` FROM `sport`.`players` AS p JOIN `sport`.`gameinstances` AS gi ON p.`id` = gi.`playerid` WHERE (p.`playerid` IN (CALL findPlayers`("Canada", "2002"))) AND (gi.`instanceid` NOT IN (CALL findGameInstances`("Canada", "2002"))); For example, the procedures 'findPlayers' and 'findGameInstances' are are stored routines that execute some SQL and return a result set. I would prefer not to include their code directly within the statement above.

  • Is it possible to create ICriteria/ICriterion from LINQ or HQL?

    - by adrin
    I am creating a method that can create filter understood by NHibernate (by filter i mean a set of ICriteria object for example) from my abstract filter object. public static IEnumerable<ICriterion> ToNhCriteria(this MyCriteria criteria) { // T4 generated function // lots of result.Add(Expression.Or(Expression.Eq(),Expression.Eq)) expression trees - hard to generate // Is there a way to generate HQL/Linq query here istead? } then i want to do something like session.CreateCriteria<Entity>().Add(myCriteria.ToNhCriteria()) to filter entities. The problem is that using Expression. methods (Expression.Or etc) is quite tedious (the method is generated and i have multiple or statements that have to be joined into an expression somehow). Is there a way to avoid using Expression.Or() and create ICrietrion / ICriteria using LINQ or HQL?

  • Is it possible to bind data asynchronously between two dropdownlists in a view?

    - by user252160
    I'd like to achieve the following effect using ASP.NET MVC and JQuery. I've got a drop down list displaying a list of Countries. I want to make it so that when I change the value of the country, a new drop down list appears below it, showing a list of companies whose country of origin is the particular selected company. The thing is that I do not want to rely too much on controller actions because I'm using it in a Template Helper which is a "headless" view. Can I bind it somehow?

  • Is ADO.NET Entity framework database schema update possible?

    - by fyasar
    I'm working on proof of concept application like crm and i need your some advice. My application's data layer completely dynamic and run onto EF 3.5. When the user update the entity, change relation or add new column to the database, first i'm planning make for these with custom classes. After I rebuild my database model layer with new changes during the application runtime. And my model layer tie with tightly coupled to my project for easy reflecting model layer changes (It connected to my project via interfaces and loading onto to application domain in the runtime). I need to create dynamic entities, create entity relations and modify them during the runtime after that i need to create change database script for updating database schema. I know ADO.NET team says "we will be able to provide this property in EF 4.0", but i don't need to wait for them. How can i update database changes during the runtime via EF 3.5 ? For example, i need to create new entity or need to change some entity schema, add new properties or change property types after than how can apply these changes on the physical database schema ? Any ideas ?

  • Is it possible to force ignore the :hover pseudoclass for iPhone/iPad users?

    - by christophercamps
    I have some css menus on my site that expand with :hover (without js) This works in a semi-broken way on iDevices, for example a tap will activate the :hover rule and expand the menu, but then tapping elsewhere doesn't remove the :hover. Also if there is a link inside the element that is :hover'ed, you have to tap twice to activate the link (first tap triggers :hover, second tap triggers link). I've been able to make things work nicely on iphone by binding the touchstart event. The problem is that sometimes mobile safari still chooses to trigger the :hover rule from the css instead of my touchstart events! I know this is the problem because when I disable all the :hover rules manually in the css, mobile safari works great (but regular browsers obviously don't anymore). Is there a way to dynamically "cancel" :hover rules for certain elements when the user is on mobile safari? I'm using jQuery.

  • In facebook connect, how can I check if a user is a fan of my facebook page? Is it possible to track

    - by Tony
    I am trying to determine if a user is a facebook fan. I load the facebook JS library and initialize: <script type="text/javascript" src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US"></script> FB_RequireFeatures(["XFBML","Connect","Api"], function() { FB.init("my_api_key","xd_receiver.htm") }); FB.ensureInit(function () { FB.ApiClient.pages_isFan(my_profile_id,"some_UID",callback); }); However when I call the API client with FB.ApiClient.pages_isFan, I get a JS error - FB.ApiClient is undefined I am also using the FBML fan tag to display the "become a fan" button: <fb:fan profile_id="my_profile_id" stream="0" connections="10" logobar="1" width="300"></fb:fan> And would like to be notified when either the "become a fan" button is clicked or a user has successfully become a fan. The business logic is pretty simple - If they become a fan, track it in my database. Then if they try to become a fan again, check with the library if they are a fan and say "You are already a fan" if they are a fan, show the widget if not.

  • Is it possible to broadcast audio to shoutcast / icecast / other server? from flash player?

    - by Jeffrey
    I am trying to create a flash client that can stream audio to an online radio server. Theoretically a user could enter the server info / login, and then connect and start sending data to the server which could then be broadcasted and listened to by other clients. I don't think this would be very hard, but am unsure about what data formats to use and what is the best server for the job. I'd like to be able to use one of the most popular radio servers like shoutCast. Any ideas? Thanks in advance.

  • Servlet Mapping Help - Possible to Avoid Referencing Context Name?

    - by AJ
    Hi all, I am working on a Spring application and trying to get my URL mapping correct. What I would like to have work is the following: http://localhost:8080/idptest -> doesn't work But instead, I have to reference the context name in my URL in order to resolve the mapping: http://localhost:8080/<context_name>/idptest -> works How can I avoid the requirement of referencing the context name in my URL without using a rewrite/proxy engine e.g. Apache? Here is the servlet definition and mapping from my web.xml: <servlet> <servlet-name>idptest</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/conf/idptest.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>idptest</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> Here's the outline of my controller (showing annotations for request mappings): @Controller @RequestMapping("/idptest") public class MyController { @RequestMapping(method=RequestMethod.GET) public String setupForm(Model model){ MyObject someObject = new MyObject(); model.addAttribute("someObject", someObject); return "myform"; } @RequestMapping(method = RequestMethod.POST) public String processSubmit(@ModelAttribute("someObject") MyObject someObject) throws Exception { // POST logic... } } Thanks!

  • Is it possible to download a .zip file into iPhone when user clicks a link inside UIWebView?

    - by Horace Ho
    In a new app, I plan to let users download their own files and stored them inside iPhone. The process is typically: iPhone present a web page by UIWebView, in which there are several links to .zip files the user browser the page and click on one of the .zip file link iPhone downloads the file into the iPhone document folder, closes WebView, acknowledges the user when download is complete How can that be done? Thanks

  • Is it possible to convert text to shape in VML /canvas/SVG ?

    - by est
    Hello, I need to display a text in 3D using vml/canvas/svg and do some transformation to the shape of the text like the effect of Ctrl+T in photoshop, even align a line of text to a curve, is there a way to convert text to shape first? The only thing close is getImageData() in firefox which is not ideal but OK. Any better methods? Using browser-specific hacks or voodoo is OK, but no Flash please :)

  • Is it possible to unit test methods that rely on NHibernate Detached Criteria?

    - by Aim Kai
    I have tried to use Moq to unit test a method on a repository that uses the DetachedCriteria class. But I come up against a problem whereby I cannot actually mock the internal Criteria object that is built inside. Is there any way to mock detached criteria? Test Method [Test] [Category("UnitTest")] public void FindByNameSuccessTest() { //Mock hibernate here var sessionMock = new Mock<ISession>(); var sessionManager = new Mock<ISessionManager>(); var queryMock = new Mock<IQuery>(); var criteria = new Mock<ICriteria>(); var sessionIMock = new Mock<NHibernate.Engine.ISessionImplementor>(); var expectedRestriction = new Restriction {Id = 1, Name="Test"}; //Set up expected returns sessionManager.Setup(m => m.OpenSession()).Returns(sessionMock.Object); sessionMock.Setup(x => x.GetSessionImplementation()).Returns(sessionIMock.Object); queryMock.Setup(x => x.UniqueResult<SopRestriction>()).Returns(expectedRestriction); criteria.Setup(x => x.UniqueResult()).Returns(expectedRestriction); //Build repository var rep = new TestRepository(sessionManager.Object); //Call repostitory here to get list var returnR = rep.FindByName("Test"); Assert.That(returnR.Id == expectedRestriction.Id); } Repository Class public class TestRepository { protected readonly ISessionManager SessionManager; public virtual ISession Session { get { return SessionManager.OpenSession(); } } public TestRepository(ISessionManager sessionManager) { } public SopRestriction FindByName(string name) { var criteria = DetachedCriteria.For<Restriction>().Add<Restriction>(x => x.Name == name) return criteria.GetExecutableCriteria(Session).UniqueResult<T>(); } } Note I am using "NHibernate.LambdaExtensions" and "Castle.Facilities.NHibernateIntegration" here as well. Any help would be gratefully appreciated.

  • Is it possible to mix orm.xml definitions with annotations when using JPA/hibernate ?

    - by hatchetman82
    I'm working on an application whihc supports using several DB vendors, with the table definitions being different for each DB type. The trouble is that the column definitions are not what hibernate expects, and so my entities contain a lot of @Column(..columnDefintion="..."...) annotations. To further complicate the issue, there's no way to specify a columnDefinition per DB. So I tried moving just the columnDefinition bits to an orm.xml file, and I have a Maven profile that bundles the correct file. JBoss 4.0.5/Hibernate 3.2.0GA fails to validate, and it seems it completely disregards the annotations given an xml file. Is there a way to make Hibernate "merge" the data from the xml with the annotations ?

  • C - is it possible to decrement the max value of a for loop from within the for loop?

    - by hatorade
    for example: void decrement(int counter) { counter--; } int counter = 20; for (int i = 0; i < counter; i++) { for (int j = 0; j < counter, j++) { decrement(counter); } } ideally, what i'd like to see is the counter var being decremented every time the for loop is run, so that it runs fewer than 20 iterations. but gdb shows that within decrement() counter is decremented, but that going back to the for loop counter actually stays the same.

  • Is my objective possible using WCF (and is it the right way to do things?)

    - by David
    I'm writing some software that modifies a Windows Server's configuration (things like MS-DNS, IIS, parts of the filesystem). My design has a server process that builds an in-memory object graph of the server configuration state and a client which requests this object graph. The server would then serialize the graph, send it to the client (presumably using WCF), the server then makes changes to this graph and sends it back to the server. The server receives the graph and proceeds to make modifications to the server. However I've learned that object-graph serialisation in WCF isn't as simple as I first thought. My objects have a hierarchy and many have parametrised-constructors and immutable properties/fields. There are also numerous collections, arrays, and dictionaries. My understanding of WCF serialisation is that it requires use of either the XmlSerializer or DataContractSerializer, but DCS places restrictions on the design of my object-graph (immutable data seems right-out, it also requires parameter-less constructors). I understand XmlSerializer lets me use my own classes provided they implement ISerializable and have the de-serializer constructor. That is fine by me. I spoke to a friend of mine about this, and he advocates going for a Data Transport Object-only route, where I'd have to maintain a separate DataContract object-graph for the transport of data and re-implement my server objects on the client. Another friend of mine said that because my service only has two operations ("GetServerConfiguration" and "PutServerConfiguration") it might be worthwhile just skipping WCF entirely and implementing my own server that uses Sockets. So my questions are: Has anyone faced a similar problem before and if so, are there better approaches? Is it wise to send an entire object graph to the client for processing? Should I instead break it down so that the client requests a part of the object graph as it needs it and sends only bits that have changed (thus reducing concurrency-related risks?)? If sending the object-graph down is the right way, is WCF the right tool? And if WCF is right, what's the best way to get WCF to serialise my object graph?

  • Is it possible to have a tableless select with multiple rows?

    - by outis
    A SELECT without a FROM clause gets us a multiple columns without querying a table: SELECT 17+23, REPLACE('bannanna', 'nn', 'n'), RAND(), CURRENT_TIMESTAMP; How can we write a query that results in multiple rows without referring to a table? Basically, abuse SELECT to turn it into a data definition statement. The result could have a single column or multiple columns. I'm most interested in a DBMS neutral answer, but others (e.g. based on UNPIVOT) are welcome. There's no technique application behind this question; it's more theoretical than practical.

  • possible to fetch @mentions thru Facebook API (like thru Twitter API?)

    - by db
    I'm looking to implement a feature where I am able to collect @mentions through the facebook API in a similar fashion to the twitter API. Specifically, if I run a group called foo, and other people on facebook mention @foo in their wall posts, I'd like to fetch and collect the text of that particular @foo mention. I can't find any relevant documentation on Facebook....

  • Possible to capture all events in a web browser?

    - by David
    I am working on a pet project and am at the research stage. Quick summary I am trying to intercept all form submits, onclick, and every single keydown. My library of choice is either jquery, or jquery + prototypejs. I figure I can batch up the events into a queue/stack and send it back to the server in time interval batches to keep performance relatively stable. Concerns Form submits and change's would be relatively simple.. Something like $("form :inputs").bind("change", function() { ... record event... }); But how to ensure I get precedence over the applications handlers as I have a habit of putting return false on a lot of my form handlers when there is a validation issue. As I understand it, that effectively stops the event in its tracks. My project For my smaller remote clients I will put their products onto a VPS or run it in my home data center. Currently I use a basic authentication system, given a username/password they see the website and then hopefully send me somewhat sane notes on what is broken or should be tweaked. As a better solution, I've written a simple proxy web server that does the above but allows me to have one DNS entry and then depending on credentials it makes an internal request relaying headers and re-writing URLS as needed. Every single html/text or application/* request is compressed and shoved into a sqlite table so I can partially replay what they've done. Now I am shifting to the frontend and would like to capture clicks, keydown's, and submits on everything on the page.
