JavaFX Line numbers doesn't work if there's no content on line -

-

I have tried to do a bit with the line number today but I have only one problem that I can not fix.

It can be calculated that if there is any material in the line, but if there is no content in it, it only says 0.

And I get text from Textaria in JavaFX. / P>

This is my simple code 

  GetArea (). SetOnKeyPressed (- of KeyEvent) -> {if (ke.getCode (.) Equals (KeyCode.ENTER)} {int m = GetArea (.) GetText (). Partition ("\ n"). Length; Out.println (m);}});  
 
 The method  split  searches for a string that matches The substrings are the regular expression, dividing the sentence at that point and leaving the matching substrings. Take a look at these examples:  
     
  •  
     "This is a test string. \ N And this is another." As a result ["This is a test string.", "And it is another."] And count 2.   
  •  
     "This is a test string \ N" result [[it is a test string.]] And therefore the result will be 1.   
     If you want to get results, you can, for example, if the last letter in the string is \ '\ n' and add 1 to line count If so, get something like this:  
      GetArea (). SetOnKeyPressed ((of KeyEvent)) - & gt; {If (ke.getCode (.) Equals (KeyCode.ENTER)) {string text = GetArea (). GetText (); Int m = text.split ("\ n") length; If (text .charAt (text.length () - 1) == '\ n') m ++; System.out.println (m);}});

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...
