  • Display the info window of a Google map marker

    - by Keyslinger
    I have succeeded in loading a Google map using the gMap jQuery plugin and making it display several markers passed to it in a JSON object using the pattern demonstrated here under "Map with marker and info window". So far, so good. Now I want to have a link on the same page which, when clicked, displays the info window for a marker on the map. How is this done?

  • Group by in Winforms/webforms DataGrid

    - by Kumar
    I'd like to implement the group by features for the default grid as it's available for the commercial grid like devexpress/infragistics et al, if you want a sample, see the 2nd image on http://www.devexpress.com/Products/NET/Controls/WinForms/Grid/dataoperations.xml I'd think there's some pattern or better yet some opensource/free grid which does this already, if not, i would probably implement it if i can find the time (doubtful ! and esp since it's available so easily in most packages, if only i can convince the client to pay for a license ) & want to get some ideas/patterns on the same

  • How significant are JPA lazy loading performance benefits?

    - by Robert
    I understand that this is highly specific to the concrete application, but I'm just wondering what's the general opinion, or at least some personal experiences on the issue. I have an aversion towards the 'open session in view' pattern, so to avoid it, I'm thinking about simply fetching everything small eagerly, and using queries in the service layer to fetch larger stuff. Has anyone used this and regretted it? And is there maybe some elegant solution to lazy loading in the view layer that I'm not aware of?

  • Compare Database container and class container

    - by Mohit Deshpande
    I am using a SQL Server database in my current project. I was watching the MVC Storefront videos (specifically the repository pattern) and I noticed that Rob (the creator of MVC Storefront) used a class called Category and Product, instead of a database and I have notice that using LINQ-SQL or ADO.NET, that a class is generated. Is there an advantage to using a class over a database to store information? Or is it the other way around? Or are they even comparable?

  • ASP.NET MVC + fluent nNibernate, what IoC tool?

    - by bondehagen
    I'm working on a ASP.NET MVC project where we have decided to use Fluent nHibernate for dataccess. To enable loose coupling we go for a IoC/DI pattern. My questions is what IoC tool to go for. I've tried to find the differences between windsor, ninject, spring, structuremap and unity, but it's difficult to see the benefits each one has to offer. Whats your experience?

  • C++ Virtual Constructor, without clone()

    - by Julien L.
    I want to perform "deep copies" of an STL container of pointers to polymorphic classes. I know about the Prototype design pattern, implemented by means of the Virtual Ctor Idiom, as explained in the C++ FAQ Lite, Item 20.8. It is simple and straightforward: struct ABC // Abstract Base Class { virtual ~ABC() {} virtual ABC * clone() = 0; }; struct D1 : public ABC { virtual D1 * clone() { return new D1( *this ); } // Covariant Return Type }; A deep copy is then: for( i = 0; i < oldVector.size(); ++i ) newVector.push_back( oldVector[i]->clone() ); Drawbacks As Andrei Alexandrescu states it: The clone() implementation must follow the same pattern in all derived classes; in spite of its repetitive structure, there is no reasonable way to automate defining the clone() member function (beyond macros, that is). Moreover, clients of ABC can possibly do something bad. (I mean, nothing prevents clients to do something bad, so, it will happen.) Better design? My question is: is there another way to make an abstract base class clonable without requiring derived classes to write clone-related code? (Helper class? Templates?) Following is my context. Hopefully, it will help understanding my question. I am designing a class hierarchy to perform operations on a class Image: struct ImgOp { virtual ~ImgOp() {} bool run( Image & ) = 0; }; Image operations are user-defined: clients of the class hierarchy will implement their own classes derived from ImgOp: struct CheckImageSize : public ImgOp { std::size_t w, h; bool run( Image &i ) { return w==i.width() && h==i.height(); } }; struct CheckImageResolution; struct RotateImage; ... Multiple operations can be performed sequentially on an image: bool do_operations( std::vector< ImgOp* > v, Image &i ) { std::for_each( v.begin(), v.end(), /* bind2nd(mem_fun(&ImgOp::run), i ...) don't remember syntax */ ); } int main( ... ) { std::vector< ImgOp* > v; v.push_back( new CheckImageSize ); v.push_back( new CheckImageResolution ); v.push_back( new RotateImage ); Image i; do_operations( v, i ); } If there are multiple images, the set can be split and shared over several threads. To ensure "thread-safety", each thread must have its own copy of all operation objects contained in v -- v becomes a prototype to be deep copied in each thread.

  • iPhone app works hundreds of times, then crashes from memory error on startup, then never works unti

    - by peter
    I have a Cocos2d/openGL iPhone game. It's a universal app and I'm dealing with an occasional but nasty error on the iPad. We are loading a lot of textures up front (3 2048x2048 textures). I'm working on reducing this up front load, but what worries me is I really don't understand the root cause of this crash that permanently breaks the app. This is the deal: 1. App works fine for hundreds of plays on the iPad 2. Eventually (I'm guessing due to other programs using up some memory and not letting go or whatever) the app starts crashing on startup. It just closes again in the middle of loading. 3. The App will now never work again on that iPad, closing immediately every time, until the iPad is restarted. Obviously my app is demanding too much memory up front to work reliably every time, I get that. What I don't get is why when it fails once, it has failed forever until the iPad is restarted. Can anyone explain what is going on here? EDIT: forgot to add organizer crash lags just say low memory, like this every time (I changed my app name to MyAppName below). Again, I know it's low memory, but why does it stay low memory until restart?: Incident Identifier: E7A2507C-3FB1-4E3B-B315-09F094236541 CrashReporter Key: 0fda9d667f2c6073f20a76809aa25438b6854d15 OS Version: iPhone OS 3.2 (7B367) Date: 2010-04-30 16:59:44 -0400 Free pages: 437 Wired pages: 17228 Purgeable pages: 0 Largest process: MyAppName Processes Name UUID Count resident pages MyAppName <6307ce41802850944baa78d29224fa7f> 22385 (jettisoned) (active) mediaserverd <ea8bac28b06fe3980fdd44b5caceb563> 242 DTMobileIS <a0f651e43881e66f50f8a95abea72921> 5826 notification_pro <4c9a7ee0a5bbe160465991228f2d2f2e> 67 syslog_relay <4ceaed776d2df957fa130712f4ef21d0> 66 notification_pro <4c9a7ee0a5bbe160465991228f2d2f2e> 67 notification_pro <4c9a7ee0a5bbe160465991228f2d2f2e> 67 afcd <4f3c9566e33b4463f05603d990584e5d> 72 ptpd <83de0f774bd6553d513ae9e19b0f9b56> 181 syslogd <66247e305d5c0bf6f1ce1cc950653263> 81 lsd <a4d852c1c8da2b3d231bdc90887b52ba> 130 iapd <a8534cbde4b90ad5915dd26ab03ff3e3> 204 notifyd <5e9d5bee7c3eae1c8b494c79eb11406e> 71 BTServer <64e4a6ea6b1240db2331e05a29caa862> 108 CommCenter <97bf297944ac4bde19bcee96dd23bd5f> 181 SpringBoard <c7a5904c12db7b14334a4edaa4cabaa9> 5339 (active) configd <aca9fa3380322669164fd6b1a3864300> 373 fairplayd.K48 <2d997ffca1a568f9c5400ac32d8f0782> 84 locationd <dd1ea88105c62173908ce767db5c4d37> 599 mDNSResponder <820560222d47a1f2a0dce98a7f8a9721> 108 lockdownd <497fd54c79a680bf29f5d9320f514613> 303 MobileStorageMou <c277b79c2157c4dc5cfc5c3ca35bd5f2> 69 launchd <66972eee4d865c4383b33d985d22994b> 98 **End**

  • Does anyone have experience simultaneously running a Drupal and Wordpress site and redirecting some

    - by DKinzer
    This is a really weird question and I apologize: I've been asked if it's possible not to import our blog from Wordpress to Drupal but just keep it in Wordpress as an archive and re-direct our users say from hostname/blog/... to hostname/wordpress/... when a URL matches the Wordpress URL pattern. I've never heard of anyone trying this and I'm wondering about pitfalls and whether or not it's even possible. Thanks! D

  • Are there any MVP Frameworks projects out there?

    - by Greg Malcolm
    MVC is used a number of popular frameworks. To name just a few, Ruby on Rails, ASP.NET MVC, Monorail, Spring MVC. Are there any equivalent frameworks using any variant of MVP? Most of the examples I've found online seem to be custom implementations of the pattern rather than reusable frameworks. Suggestions need not be specific to any particular programming language, my interest is mostly academic.
