问题 I have a scenario which I think is pretty common in Android applications. I know partial attempts of solving the issue were made, but until now I have not stumbled upon the full implementation.

So basically my case is the following: I have list view showing image loaded from the web and text per each row. I want to lazily load the images, placing default for each image and

阅读更多关于 Is automapper preventing lazy loading with EF?

问题 I have been using an AutoMapper and it seems that it gets me all the child entities (even if I don't specify them in "Include()" clause). Is there any way how to make lazy loading possible and get child properties only if I specify them. Thank you, Jakub 回答1: After mapping you will have mapped object without any references to source entity (which holds database context for lazy loading). Only property values are copied to destination entity. So you will not be able to do any lazy-loading

阅读更多关于 Lazy module variables--can it be done?

问题 I'm trying to find a way to lazily load a module-level variable. Specifically, I've written a tiny Python library to talk to iTunes, and I want to have a DOWNLOAD_FOLDER_PATH module variable. Unfortunately, iTunes won't tell you where its download folder is, so I've written a function that grabs the filepath of a few podcast tracks and climbs back up the directory tree until it finds the "Downloads" directory. This takes a second or two, so I'd like to have it evaluated lazily, rather than at

问题 I'm using code first EF5 and I have an object which has a collection defined as virtual (lazy loaded). This returns data when called. However I want it to be eager loaded. I've removed virtual from the property signature but now it always returns null data. EF doesn't even run the query , can anyone help? Edit: I know about .include() I'd just prefer to use the non-virtual property method of doing it. Objects User ( [Key] Id is on Resource object which is the Parent of person class):

问题 I found Fedor's code here and implemented it into my project. The only difference is that my application does not have a list view, rather, I am accessing 1 image at a time from the server. When the activity launches, i call "DisplayImage(...)" to show the first picture. Then there are 2 buttons (previous/next) that when clicked, they call "DisplayImage(...)". It works fine for a little while, but then I get an Out of Memory error. At the top of his code, he comments that you may want to use
