  • 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

  • Mercurial: Diff current source vs source at point in time

    - by Marcus
    I know how to view all changes in a changeset.. But let's say you update your source, you do a pull and you get 3 new changesets. How can you compare the current state of the remote repository (with the 3 changesets checked in) vs. the current source (on your local machine)? I'd like to do this using the visual diff tool which I currently have configured (Examdiff or Kdiff3).

  • Using WINAPI ReadConsole

    - by Jim Fell
    I am trying to use the WINAPI ReadConsole() to wait for any keypress at the end of my Win32 console application. CONSOLE_READCONSOLE_CONTROL tControl; char pStr[65536]; DWORD dwBufLen = 1; DWORD dwCtl; tControl_c.nLength = sizeof( CONSOLE_READCONSOLE_CONTROL ); tControl_c.nInitialChars = 0; tControl_c.dwControlKeyState = 0; tControl_c.dwCtrlWakeupMask = NULL; pBuf[0] = 0x00; do { ReadConsole( hConsole_c, pStr, (*pBufLen) * sizeof(TCHAR), pBufLen, &tControl ); } while ( pStr[0] == 0x00 ); The code executes without throwing an exception. However, when the ReadConsole() function executes the error code ERROR_INVALID_HANDLE (0x06) is flagged. I have verified hConsole_c to be a valid handle. Does anyone have any insight as to what I am doing wrongly? I am using Visual C++ 2008 Express Edition. Thanks.

  • Sql query - how to construct

    - by Max Malmgren
    Hi. I am working to implement a dataconnection between my C# application and an Sql Express database. Please bear in mind I have not worked with Sql queries before. I have the following relevant tables: ArticlesCommon ArticlesLocalized CategoryCommon CategoryLocalized where ArticlesCommon holds language independent information such as price, weight etc. This is the statement for now: SELECT * FROM ArticlesCommon INNER JOIN ArticlesLocalized ON ArticlesCommon.ID = ArticlesLocalized.ID WHERE ArticlesLocalized.Language = @language ORDER BY ArticlesCommon.DateAdded ArticlesCommon contains a category id for each row. Now, I want to use this to look up the localized information in CategoryLocalized and add it to the result, something like SELECT *, CategoryLocalized.Name as CategoryName. If I have gotten my point across, is this doable? Thank you.

  • iPhone Localization: simple project not working

    - by gonso
    Hello Im doing my first localized project and I've been fighting with it for several hours with no luck. I have to create an app that, based on the user selection, shows texts and images in different languages. I've read most of Apple's documents on the matter but I cant make a simple example work. This are my steps so far: 1) Create a new project. 2) Manually create a "en.lproj" directory in the projects folder. 3) Using TexEdit create file called "Localizable.strings" and store it in Unicode UTF-16. The file looks like this: /* Localizable.strings Multilanguage02 Created by Gonzalo Floria on 5/6/10. Copyright 2010 __MyCompanyName__. All rights reserved. */ "Hello" = "Hi"; "Goodbye" = "Bye"; 4) I drag this file to the Resources Folder on XCode and it appear with the "subdir" "en" underneath it (with the dropdown triangle to the left). If I try to see it on XCode it looks all wrong, whit lots of ? symbols, but Im guessing thats because its a UTF-16 file. Right? 5) Now on my view did load I can access this strings like this: NSString *translated; translated = NSLocalizedString(@"Hello", @"User greetings"); NSLog(@"Translated text is %@",translated); My problem is allowing the user to switch language. I have create an es.lproj with the Localizable.strings file (in Spanish), but I CANT access it. I've tried this line: [[NSUserDefaults standardUserDefaults] setObject: [NSArray arrayWithObjects:@"es", nil] forKey:@"AppleLanguages"]; But that only works the NEXT time you load the application. Is there no way to allow the user to switch languages while running the application?? Do I have to implement my own Dictionary files and forget all about NSLocalizableString family? Thanks for ANY advice or pointers. Gonso

  • MySQL bindings for Rails 2.3.5 on Mac OS X 10.5.8

  • Accessing a share point site using the object model.

    - by Prashanth
    Hi I am trying to access a share point site using the SP object model from a console application. I am trying to do something like this.. SPSite site = new SPSite(sitePath) //Operations go here This works fine when the share point site and the console app are on the same machine. However when the console app and the site are on different machines, I get an error "The Web application at "http://server/url" could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application" Here are the things that I have already done: 1) I have tried accessing the site via both IP address as well as machine name, assuming that it could be a DNS resolution issue. 2) Initially I impersonated using a farm admin account, still i could not access. Then I added myself as the farm admin, still no joy. 4) The site is accessible via IE. So it is not a permission issue I guess. 5) I have tried almost all the solutions suggested by various links obtained by googling the error message. I am trying this on share point 2010. A similar issue occurs on 2007 also. Sometimes its kind of frustrating to do SharePoint development , since I get the feeling of stumbling from one error to the next, with no clue as to what could be wrong and the error messages not being helpful in the least :(

  • Making Global Struct in C++ Program

    - by mosg
    Hello world! I am trying to make global structure, which will be seen from any part of the source code. I need it for my big Qt project, where some global variables needed. Here it is: 3 files (global.h, dialog.h & main.cpp). For compilation I use Visual Studio (Visual C++). global.h #ifndef GLOBAL_H_ #define GLOBAL_H_ typedef struct TNumber { int g_nNumber; } TNum; TNum Num; #endif dialog.h #ifndef DIALOG_H_ #define DIALOG_H_ #include <iostream> #include "global.h" using namespace std; class ClassB { public: ClassB() {}; void showNumber() { Num.g_nNumber = 82; cout << "[ClassB][Change Number]: " << Num.g_nNumber << endl; } }; #endif and main.cpp #include <iostream> #include "global.h" #include "dialog.h" using namespace std; class ClassA { public: ClassA() { cout << "Hello from class A!\n"; }; void showNumber() { cout << "[ClassA]: " << Num.g_nNumber << endl; } }; int main(int argc, char **argv) { ClassA ca; ClassB cb; ca.showNumber(); cb.showNumber(); ca.showNumber(); cout << "Exit.\n"; return 0; } When I`m trying to build this little application, compilation works fine, but the linker gives me back an error: 1>dialog.obj : error LNK2005: "struct TNumber Num" (?Num@@3UTNumber@@A) already defined in main.obj Is there exists any solution? Thanks.

  • Can I send a variable to paypal, and have it post it back to me when payment completes?

    - by Yegor
    Ive been using express checkout API to convert people's accounts on my site to premium accounts after paying. The only problem with it is that it doesn't send the user back to the site until they click the button to return, and it updates their permission when that happens. About 40% of the users don't seem to do that.... so their accounts never get credited after payment. Although paypal does an instant post-back upon the successful payment, I was never able to make it actually update the user's account right away, since I cant get it to send back some sort of informational that would identify the user that just completed the payment. I could only do that when you are sent back to the site, which sends the transaction ID, that I logged with a post-back. It searches for it, and grants permission if it was found int he DB. Is there a way to submit some sort of a variable to paypal, that it will then post back to me? Something like &user_id=123, which would make it very handly to update the user's permission.

  • Android - Basic CRUD (REST/RPC client) to remote server

    - by bsreekanth
    There are lot of discussion about REST client implementation in android, based on the talk at GoogleIO 2010, by Virgil Dobjanschi. My requirement may not necessarily involved, as I have some freedom to choose the configuration. I only target tablets configuration changes can be prevented if no other easy way (fix at Landscape mode etc) I am trying to achieve. Basic CRUD operation to my server (JSON RPC/ REST). Basically mimic an ajax request from android app (no webview, need native app) Based on the above mentioned talk, and some reading I see these options. Implement any of the 3 mentioned in the Google IO talk Especially, the last pattern may be more suitable as I don't care much of caching. But not sure how "real time" is sync implementation. Use HTTP request in AsyncTask. Simplest, but need to avoid re-sending request during change in device configuration (orientation change etc). Even if I fix at one orientation, recreation of activity still happens. So need to handle it elegantly. Use service to handle http request. So far, it say use service for long ruiing request. Not sure whether it is a good approach for simple GET/POST/PUt requests. Please share your experience on what could be the best way.

  • Cross-browser method for hiding page elements until all content is loaded to prevent layout from appearing broken during load?

    - by Ryan
    I have an issue where due to some elements loading faster than others, the page looks broken for a few seconds at the start. An example is the CSS Pie behavior that allows me to do curved corners in IE, it appears before it becomes curved which looks bad. What would be ideal would be it somehow knowing when everything is loaded and then appear all at once, possibly including some kind of elegant visual way of not making the user feel impatient... any ideas or common tricks for doing this?

  • Simple way of getting the Last.fm artist image for recently listened songs?

    - by animuson
    On the Last.fm website, your recently listened track include the 34x34 (or whatever size) image at the left of each song. However, in the RSS feed that they give you, no image URLs are provided for the songs. I was wondering if there was a good way of figuring out the ID for the image that needs to be used for that artist and displaying it based on the data that we're given. I know it is possible to load the artist page from their website and then grab the image values from JavaScript, but that seems overly complicated and would probably take quite some time to do. What we're given: <item> <title>Owl City – Rainbow Veins</title> <link>http://www.last.fm/music/Owl+City/_/Rainbow+Veins</link> <pubDate>Thu, 20 May 2010 18:15:29 +0000</pubDate> <guid>http://www.last.fm/user/animuson#1274379329</guid> <description>http://www.last.fm/music/Owl+City</description> </item> and the 34x34 image for this song would be here (ID# 37056785). Does anything like this exist? I've considered storing the ID number in a cache of some sort once it has been checked once, but what if the image changes?

  • Vertical text alignment in Crystal Reports?

    - by George Mauer
    In the Crystal Reports editor that comes with Visual Studio (2008) is it possible to align text to the center of a text box rather than to the top? I can't find the option anywhere and a Google search is not encouraging but I just can't bring myself to believe that they would not include such an obvious feature.
