  • Is it possible to change WCF service without regenerating & recompiling client proxy?

    - by Buu Nguyen
    Let's say I have a WCF service which has a method returning object Person. In one of the clients of this service, I can add service reference to the service and start using its method. Now, let's say the Person class is changed on the server, having a new DataMember added. Other clients will make use of this new DataMember, but my client doesn't. Therefore, this client shouldn't even be aware that the service returns s/t "more" than what it needs. Is there any way that my client can still work with the service without having to update the service reference (which, as I understand, means regenerating the proxy & compiling it)?

  • Is the video recording possible in the background service?

    - by pyt
    Hello, All. I've tried video recording in the background. But had failed. Under normal circumstances, the recording works properly. However, if HOME key down- Home screen or Other Activity is running, recording terminates. In such a situation, I want to record continuously. I want to record whole process! What should I do? thanks. -Michael

  • Is it possible to combine these 3 mySQL queries?

    - by Greenie
    I know the $downloadfile - and I want the $user_id. By trial and error I found that this does what I want. But it's 3 separate queries and 3 while loops. I have a feeling there is a better way. And yes, I only have a very little idea about what I'm doing :) $result = pod_query("SELECT ID FROM wp_posts WHERE guid LIKE '%/$downloadfile'"); while ($row = mysql_fetch_assoc($result)) { $attachment = $row['ID']; } $result = pod_query("SELECT pod_id FROM wp_pods_rel WHERE tbl_row_id = '$attachment'"); while ($row = mysql_fetch_assoc($result)) { $pod_id = $row['pod_id']; } $result = pod_query("SELECT tbl_row_id FROM wp_pods_rel WHERE tbl_row_id = '$pod_id' AND field_id = '28'"); while ($row = mysql_fetch_assoc($result)) { $user_id = $row['pod_id']; }

  • Is it possible to take a screenshot of a web page with Javascript or HTML5/Canvas?

    - by Ryan Kearney
    Is there a way I could insert some code into a page that would take a screenshot of what the user sees in the browser window, then upload that image via a web form of some sort? I'm working on a clone of a pay-to-use service that lets you install a widget on a web page which in turn allows viewers to report bugs in the sites layout. Currently they use a Java applet to take the screenshot, which, in my opinion, is probably the worst way to go about it (aside from requiring the user to install a plugin) Is there a javascript/flash/other alternative? Thanks

  • Is it possible to restrict instantiation of an object to only one other (parent) object in VB.NET?

    - by Casey
    VB 2008 .NET 3.5 Suppose we have two classes, Order and OrderItem, that represent some type of online ordering system. OrderItem represents a single line item in an Order. One Order can contain multiple OrderItems, in the form of a List(of OrderItem). Public Class Order Public Property MyOrderItems() as List(of OrderItem) End Property End Class It makes sense that an OrderItem should not exist without an Order. In other words, an OrderItem class should not be able to be instantiated on its own, it should be dependent on an Order class to contain it and instantiate it. However, the OrderItem should be public in scope so that it's properties are accessible to other objects. So, the requirements for OrderItem are: Can not be instantiated as a stand alone object; requires Order to exist. Must be public so that any other object can access it's properties/methods through the Order object. e.g. Order.OrderItem(0).ProductID. OrderItem should be able to be passed to other subs/functions that will operate on it. How can I achieve these goals? Is there a better approach?

  • In an Android TextView, is it possible to insert paragraphs?

    - by johnrock
    Below is an example of the type of problem that I have. I have data in a pojo that I need to display in a textview... the data has pseudo code that denotes each paragraph with [p] I would like to somehow parse the [p]'s into paragraphs when they are displayed in the textview. Can this be done? Is there something I can substitute for the [p] that will make a new paragraph in the textview? Question question = new Question(); question.setText("Here is the first paragraph.[p] And this should be the second."); TextView view = (TextView) findViewById(R.id.qtext); view.setText(question.getParsedText());

  • Is Accessing USB from web application for cross browser cross os possible at all ?

    - by Ved
    Hey Guys, I am wondering if there is anyway we can achieve this. I heard different things about Silverlight 4 , Java Script or Active X control but not seen any demo of code for any of them. Does anyone know any web component that is available or how to write one. We really like capture client's USB drive via Web and read/write data on it. This has to work for ANY Operating system in Any web browser. Thanks UPDATED What about WPF in browser mode...I read that I can host my wpf apps inside browser and sort of like smart client. Here is a great example of doing this via silverlight 4 but author mentions about possibility of accessing USB on MAC via 1) Enable executing AppleScripts. This option will let us have the same amount of control on a mac machine as we do on a windows machine. 2) Add an overload to ComAutomationFactory.CreateObject() that calls the “Tell Application” command under the scenes and gets a AppleScript object. This option would work extremely well for Office automation. For any other operating system feature, you’ll have to code OS access twice.  I did not quite understand it. Has any tried this ?

  • java System.nanoTime is really slow. Is it possible to implement a high performance java profiler?

    - by willpowerforever
    I did a test and found the overhead of a function call to System.nanoTime() is at least 500 ns on my machine. Seemed that it is very hard to have a high performance java profiler. For enterprise software, suppose a function takes about 350 seconds and has 12,500,000,000 times of method calls. Therefore, the number of calls to System.nanoTime() is: 12,500,000,000 * 2 = 25,000,000,000 (one for start timestamp, one for end timestamp) And the overhead of System.nanoTime in total is: 500 ns * 25,000,000,000 = 500 * 25000 s = 12500000s. Note: all data from real case. Any better way to acquire the timestamp?

  • Convert Stream to IEnumerable. If possible when "keeping laziness"

    - by Binary255
    Hi, I recieve a Stream and need to pass in a IEnumerable to another method. public static void streamPairSwitchCipher(Stream someStream) { ... someStreamAsIEnumerable = ... IEnumerable returned = anotherMethodWhichWantsAnIEnumerable(someStreamAsIEnumerable); ... } One way is to read the entire Stream, convert it to an Array of bytes and pass it in, as Array implements IEnumerable. But it would be much nicer if I could pass in it in such a way that I don't have to read the entire Stream before passing it in. public static IEnumerable<T> anotherMethodWhichWantsAnIEnumerable<T>(IEnumerable<T> p) { ... // Something uninteresting }

  • Possible to access gdata api when using Java App Engine?

    - by PCBEEF
    I have a dilemma where I want to create an application that manipulates google contacts information. The problem comes down to the fact that Python only supports version 1.0 of the api whilst Java supports 3.0. I also want it to be web-based so I'm having a look at google app engine, but it seems that only the python version of app engine supports the import of gdata apis whilst java does not. So its either web based and version 1.0 of the api or non-web based and version 3.0 of the api. I actually need version 3.0 to get access to the extra fields provided by google contacts. So my question is, is there a way to get access to the gdata api under Google App Engine using Java? If not is there an ETA on when version 3.0 of the gdata api will be released for python? Cheers.

  • Symfony 1.4: Is it possible to prevent escaping of a redirect URL?

    - by Tom
    Hi, If I do a redirect in action as normal: $this->redirect('@mypage?apple=1&banana=2&orange=3'); ... Symfony produces the correct URL: /something/something?apple=1&banana=2&orange=3 However, the following gets escaped for some bizarre reason: $string = 'apple=1&banana=2&orange=3'; $this->redirect('@mypage?'.$string); ... and the following URL is produced: /something/something?apple=1&amp;banana=2&amp;orange=3 Is there a way to avoid this escaping and have the ampersands appear correctly in the URL? I've tried everything I can think of and it's driving me mad. I need this for a situation where I'm pulling a saved query as a string from the database and would just like to latch it onto the URL. I'm aware that I could generate an array from the string and then generate a brand new URL from the array, but it just seems like a lot of overhead because of this silly escaping. Thanks.

  • Is it possible to defer member initialization to the constructor body?

    - by Kjir
    I have a class with an object as a member which doesn't have a default constructor. I'd like to initialize this member in the constructor, but it seems that in C++ I can't do that. Here is the class: #include <boost/asio.hpp> #include <boost/array.hpp> using boost::asio::ip::udp; template<class T> class udp_sock { public: udp_sock(std::string host, unsigned short port); private: boost::asio::io_service _io_service; udp::socket _sock; boost::array<T,256> _buf; }; template<class T> udp_sock<T>::udp_sock(std::string host = "localhost", unsigned short port = 50000) { udp::resolver res(_io_service); udp::resolver::query query(udp::v4(), host, "spec"); udp::endpoint ep = *res.resolve(query); ep.port(port); _sock(_io_service, ep); } The compiler tells me basically that it can't find a default constructor for udp::socket and by my research I understood that C++ implicitly initializes every member before calling the constructor. Is there any way to do it the way I wanted to do it, or is it too "Java-oriented" and not feasible in C++? I worked around the problem by defining my constructor like this: template<class T> udp_sock<T>::udp_sock(std::string host = "localhost", unsigned short port = 50000) : _sock(_io_service) { udp::resolver res(_io_service); udp::resolver::query query(udp::v4(), host, "spec"); udp::endpoint ep = *res.resolve(query); ep.port(port); _sock.bind(ep); } So my question is more out of curiosity and to better understand OOP in C++

  • Port forwarding in C#/software possible? Isn't it only managed by the router?

    - by Rudi
    Isn't port forwarding managed by the router? Like, I've googled up some software applications that seem to port forward with great success, but it technically seems to be impossible. The packet must first go to the router. The router must forward it to the correct computer based on port forwarding rules. So how can a software application manage port forwarding if the packet must GO to the computer running this software application in the first place, meaning that port forwarding already is successful in the first place?

  • 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.

  • Is It Possible To Spring Autowire the same Instance of a protoype scoped class in two places

    - by Mark
    Hi ** changed the example to better express the situation i am using spring 2.5 and have the following situation @Component @Scope("prototype") Class Foo { } class A { @Autowired Foo fooA; } class B { @Autowired Foo fooB; } class C { @Autowired Foo fooC; } i am trying to understand if there is some way to use @Autowired and bind the same instance of FOO onto fooA and fooB while binding a different instance to fooC i understand that if the scope of FOO will be singleton it will work but i am wandering if there is a way to achieve the same goal while using a protoype scope. also please explain is this the correct usage of the autowiring concept ? am i trying to abuse the spring framework purpose

  • Is it possible to redirect non-HTML files with HTTP? And chaining redirects?

    - by Earlz
    Hello, I have been thinking about a neat way of load balancing and one thing that would be required is to be capable of loading an image on an HTML page from multiple locations without rewriting the URL(on each load) So what I need to be able to do is have one URL which is the "static" URL. Such as http://example.com/myimage.png The image is not actually contained in example.com though. So example.com does a either a 302 or 301 or 307 HTTP response to cause a redirect to 2.example.com. How do browsers handle this with images like in this situation? Also, how do browsers handle multiple redirections for instance if 2.example.com also didn't contain it and it went to 3.example.com ? (Note, I am asking this because I've never seen a 301 redirect on anything but an HTML page) Also, which status code would be best to use. 301 means "moved permanently" which this "move" isn't permanent so I don't want it cached. Should I use 307? Is that supported by search engines and modern browsers?

  • Analysis Services with excel as front end - is it possible to get the nicer UI that powerpivot provi

    - by AJM
    I have been looking into PowerPivot and concluded that for "self service BI" and ahoc buidling of cubes it has its uses. In particular I like the enhanced UI that you get from using PowerPivot rather than just using a PivotTable hooked up to an analysis services datasource. However it seems that hooking up PowerPivot to an existing analysis services cube is not a solution for "organisational BI". It is not always desireable to suck millions of rows into excel at once and the interface between PowerPivot and analysis services is very poor in my book. Hence the question is can an existing analysis services solution get the enhanced ui features that power pivot brings, withoout using powerpivot as the design tool? If powerpivot is aimed ad self service/personal BI then it seems bizare that the UI for this is better than for bigger/more costly analysis services solutions.

  • Is it possible to create a domain model for legacy code without refactoring?

    - by plaureano
    I currently have a client that wants me to 'abstract' out a domain model from the existing code but they specifically said that I shouldn't refactor the existing code itself. My question is 1) whether or not this is advisable and 2) what techniques would you apply in this scenario if you can't refactor the code yet they expect you to come up with a model for it? (EDIT: I can't quite put my finger on it, but somehow, not being able to refactor in this case just feels wrong. Has anyone else run into this type of scenario?)

    my site is aimed purely at the laptop market (dont ask why or argue!), all my users (or 95%+) we on a screen width of 1200+, netbooks are now taking off, with a resolution of 1024 wide. my site still looks great on a netbook if you zoom out once (ctrl-minus), but i don't want to rely on users knowing about ctrl-minus. what are my options besides redesign? I'm keen not to have zoom buttons on my page. is there a javascript zoomer outer?!!!

  • Commit in SVN without letting other to checkout - is it possible?

    - by strDisplayName
    Hey everybody, I am using SVN as my source control with ANKH and TortoiseSVN. I am writing a huge change in a project, and it takes a few days to make the change, but in the meantime I still want to commit once in a while for backup. But if I commit other team members will get updated with my unfinished work. Is there a way that I can "commit for backup" without changing the revision (so other won't get updated with my changes)? Thanks!
