问题 I am using Microsoft.WindowsAzure.StorageClient to manipulate blobs on Azure storage. I have come to the point where the user needs to list the uploaded files and modify/delete them. Since there are many files in one container, what is the best way to query azure storage services to return only the desired files.

问题 I have an odd case where adding a record is causing unwanted loading of a related collection. For example, I have Requests and Sessions. A Session can contain many Requests. I already have loaded the session, and just want to add a new request. However, when I set call AddObject on the ObjectSet of the Request repository, SQL Profiler shows a select query getting executed on all related requests on that session. Here is the problem code: this._request = new Request { Action = (string

问题 I am attempting to lazy load a controller and template in my UI-Router router.js file, but am having difficulty with the template. The controller loads properly, but after that is loaded, we must load the template and this is where things go wrong. After ocLazyLoad loads the controller, we resolve an Angular promise which is also included in the templateProvider. The issue is instead of returning the promise (templateDeferred.promise) after the file is done loading, the promise is returned as

问题 I have a service that gets a JPA entity from outside code. In this service I would like to iterate over a lazily loaded collection that is an attribute of this entity to see if the client has added something to it relative to the current version in the DB. However, the client may have never touched the collection so it's still not initialized. This results in the well known org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.example.SomeEntity. Of

问题 let's say we have a CountryList object in our application that should return the list of countries. The loading of countries is a heavy operation, so the list should be cached.
