load

try { x = session.load(...); y = x; } catch(Exception e) { //do something } If the key is not present, will load(...) throw an exception right away will return a proxy and then throw an exception when the object is trying to be obtained from the db later? Also, in the code above, if the execution reaches the assignment y = x, is it guaranteed that at that point, x is not null? Are there situations where x can be null at that point? In short: x will not be null after the load, so neither will y There may or may not be an exception from load() if the object doesn't exist If there is no exception

Whenever I try to load a PNG using SDL_Image's IMG_Load function it gives the error Failed loading libpng16-16.dll: . I have all the right dll's in the right path and I can use other parts of SDL_Image, but for some reason it can't load the libpng dll. How can I fix this? Any help is appreciated. See my article " SDL2: Loading Images with SDL_image ": If you're going to run from Visual Studio, make sure the image is in the same folder as your main.cpp file; otherwise if you're running straight from the executable, the image should be in the same folder with it. Needless to say, what I wrote

I am trying to load an .rda file in r which was a saved dataframe. I do not remember the name of it though. I have tried a<-load("al.rda") which then does not let me do anything with a. I get the error Error:object 'a' not found I have also tried to use the = sign. How do I load this .rda file so I can use it? I restared R with load("al.rda) and I know get the following error Error: C stack usage is too close to the limit Use 'attach' and then 'ls' with a name argument. Something like: attach("al.rda") ls("file:al.rda") The data file is now on your search path in position 2, most likely. Do:

I searched everywhere for this but no one appears to have an answer. My simple question is: Is there a way to preload an activity? I need this because I use a tab,and a tab has multiple activities. One of my activities is a rss reader,and it loads pretty hard(about 2-3 seconds). All I found on the web is a joke.Everyone has an opinion,but no one can point you to a sample code. Waiting for an answer,thanks! This is the code that loads the feed: At onCreate: // go get our feed! feed = getFeed(RSSFEEDOFCHOICE); // display UI UpdateDisplay(); countdown(); And the functions: private RSSFeed getFeed

I'm having some trouble understanding how codeigniters loading works. Well first you have the autoload which seems pretty straight forward, it loads everything everytime. So this sounds good to use for the stuff I use all the time. Second you can load everything inline. But here is my question: How long does it stay loaded? Let say I load the form validation library in the controller, then I load the model, can I use the form validation in the model or do I have to reload it again? Continuing let say I load a view and another controller, can I use the form validation? Or do I need to load?

I don't think this question has been posed before, at least not in the way I need it answered. I'm using jQuery's .load function. I have a problem when loading just page fragments. When using something like: $('#content').load('loadTest.html'); All of the scripts on loadTest.html load just fine. However, when loading page fragments like this: $('#content').load('loadTest.html #content'); the scripts are stripped out prior to the DOM being updated This is clearly documented in http://api.jquery.com/load/ which says: Note: When calling .load() using a URL without a suffixed selector expression,
