  • initialize a const array in a class initializer in C++

    - by Nathan Fellman
    I have the following class in C++: class a { const int b[2]; // other stuff follows // and here's the constructor a(void); } The question is, how do I initialize b in the initialization list, given that I can't initialize it inside the body of the function of the constructor, because b is const? This doesn't work: a::a(void) : b([2,3]) { // other initialization stuff } Edit: The case in point is when I can have different values for b for different instances, but the values are known to be constant for the lifetime of the instance.

  • Accessing Sharepoint tasks via web services?

    - by scooterhanson
    I've looked at a lot of the previous questions asked about sharepoint and accessing objects via web-services, and I am pretty convinced that tasks can be accessed through the Lists interface. Can anybody please verify this for me? Also, if anyone has any examples of this I would be very grateful. I'm not a Sharepoint guy but I need to connect to an instance just to retrieve task objects.

  • How to get MS Word templates directory for another user?

    - by Steve
    I'm using the following code to get the path where Word stores its templates: WordTemplatePath:=WordApp.Options.DefaultFilePath[$00000002]; The problem is that this returns the path for the actual, logged-in user. Is there a way to get the path for another user of the same Windows instance? I need it so my installer program can install the templates used by my program for other users as well.

  • Using a model to represent the overall state of a view

    - by James P.
    Is there a standard practise for representing the state of a user interface that is not linked to a single Component? For example, a Swing interface could have a series of tabs with a constraint that a single tab should only be displayed once per a given entity type (this could be represented as a HashSet). Or a message could give the result of the last operation carried out. Or a JPanel could be linked to a single entity instance for editing purposes.

  • Not sure what happens to my apps objects when using NSURLSession in background - what state is my app in?

    - by Avner Barr
    More of a general question - I don't understand the workings of NSURLSession when using it in "background session mode". I will supply some simple contrived example code. I have a database which holds objects - such that portions of this data can be uploaded to a remote server. It is important to know which data/objects were uploaded in order to accurately display information to the user. It is also important to be able to upload to the server in a background task because the app can be killed at any point. for instance a simple profile picture object: @interface ProfilePicture : NSObject @property int userId; @property UIImage *profilePicture; @property BOOL successfullyUploaded; // we want to know if the image was uploaded to out server - this could also be a property that is queryable but lets assume this is attached to this object @end Now Lets say I want to upload the profile picture to a remote server - I could do something like: @implementation ProfilePictureUploader -(void)uploadProfilePicture:(ProfilePicture *)profilePicture completion:(void(^)(BOOL successInUploading))completion { NSUrlSession *uploadImageSession = ..... // code to setup uploading the image - and calling the completion handler; [uploadImageSession resume]; } @end Now somewhere else in my code I want to upload the profile picture - and if it was successful update the UI and the database that this action happened: ProfilePicture *aNewProfilePicture = ...; aNewProfilePicture.profilePicture = aImage; aNewProfilePicture.userId = 123; aNewProfilePicture.successfullyUploaded = NO; // write the change to disk [MyDatabase write:aNewProfilePicture]; // upload the image to the server ProfilePictureUploader *uploader = [ProfilePictureUploader ....]; [uploader uploadProfilePicture:aNewProfilePicture completion:^(BOOL successInUploading) { if (successInUploading) { // persist the change to my db. aNewProfilePicture.successfullyUploaded = YES; [Mydase update:aNewProfilePicture]; // persist the change } }]; Now obviously if my app is running then this "ProfilePicture" object is successfully uploaded and all is well - the database object has its own internal workings with data structures/caches and what not. All callbacks that may exist are maintained and the app state is straightforward. But I'm not clear what happens if the app "dies" at some point during the upload. It seems that any callbacks/notifications are dead. According to the API documentation- the uploading is handled by a separate process. Therefor the upload will continue and my app will be awakened at some point in the future to handle completion. But the object "aNewProfilePicture" is non existant at that point and all callbacks/objects are gone. I don't understand what context exists at this point. How am I supposed to ensure consistency in my DB and UI (For instance update the "successfullyUploaded" property for that user)? Do I need to re-work everything touching the DB or UI to correspond with the new API and work in a context free environment?

  • What is the best way to create a Singleton Webservice in PHP?

    - by ChronoFish
    Hello, We have a need to access a DB that only allows one connection at a time. This screams "singleton" to me. The catch of course is that the singleton connection will be exposed (either directly or indirectly) via a web-service (most probable a SOAP based web-service - located on a separate server from the calling app(s) ) - which means that there may be more than one app / instance attempting to connect to the singleton class. In PHP, what is the best way to create a global singleton or a web-service singleton? TIA

  • how do I use mod_rewrite for just one file?

    - by Angela
    I want to use mod-rewrite for just one file instance: www.domain.com/contact to pull from www.domain.com/contact.php I used a rewrite rule for all files that look like a directory to do this initially but it messed up some diretory redirects I created so in the short-term, I'd rather just do it for a specific file. Thanks.

  • How to reference a class that implements certain interface?

    - by vikp
    Hi, I have an interface for logging the exceptions, i.e. IExceptionLogger. This interface has 3 implementations: DBExceptionLogger, XMLExceptionLogger, CSVExceptionLogger. I have an application that will make a use of DBExceptionLogger. The application references only IExceptionLogger. How do I create an instance of DBExceptionLogger within the application. I can't reference the DBExceptionLogger directly since it will break the purpose of having IExceptionLogger interface. Thanks
