c# - Download images from web and use downloaded images when presen -


My C # program needs to display several possible images at a time. The images are on the web and I have the exact URL for each. The program needs to either load the image from the web or, if it has been previously loaded, load it with memory / file (as from the web The previous load should be saved in memory / file). How do I implement this? I can get loading from the web with the WebRequest object, but later, fast, not enough to save it for use. 

  WebRequest request = WebRequest.Create (imageURL); Stream stream = request GetResponse () GetResponseStream (); PictureBoxFirstPack.Image = Image.FromStream (stream);    
 
 
 I'm sure you should be able to:    memorystream ms = new memorystream (); Stream.CopyTo (ms); Byte [] data = MS. ToArray ();   
 Once you take it as a byte array, you can keep it in a dictionary, database or anywhere you want.

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
