ios - What is the hexadecimal part in the Documents folder's path? -

-

I have a file in my app's document folder. When the app is finished, I save the url of the file in the applicationWillTerminate method of the appadailate: // archiver init code [archiver encodeObject: file.URL forKey: kFileURL];

To complete the file encoding and write the data

but the file manager file was not detected when trying to restore the file Can: After Calling 

  NSURL * fileURL = [Without Rectangle Decoded ObjectFor: kFileURL]; NSString * filePath = fileURL.path;   
 method  
  [[NSFileManager defaultManager] filesyxist: filepath]; Returns   
  no .  
 I tried to find the reason for this and I came to know that the  document  code> changes the folder changes with each app launch which is the hexadecimal folder in the middle. Here are two examples Given:  
  / personal / var / mobile / application / 04083 A4A-87 ACC-4E3C-8Ba1-F002B97AE304 / document /. .. / private / var / mobile / applications / 65 D1 36BA-42C3-887A-B947-7FE396978153 / document / ...   
 I always thought that the heck Sadesiml part of the ID of a specific type for every application, but as it changes: the number is exactly what? And how do I delete my file again and then launch my app?   
 
 
 You simply load your file for the Directory document folder and then.  
  + (NSString *) documentDatePath {NSArray * path = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); If ([path count] == ​​0) {return zero; } NSString * directory = [path object at indexX: 0]; If (directory == blue) {NSLog ("NSDocumentDirectory not found!"); } Return directory; }

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
