Java addWindowListener syntax error -

-

I'm looking for Google in the morning and this website, but I really do not know what I'm doing wrong. I have created a class (walboard) and I am trying to call it, but when it is compiled, there are errors on "add-window listener".

This is the error that I get: 

  Error: The constructor wallboard version can not be applied to the type of wallboard given; AddWindowListener (new wardboard (this)); ^ Required: No argument found: The reason for the wallboard: The actual and formal logic lists vary in length   
 And this is the code:  
  Public class Runabout extends to the Walboard JFrame {JLabel WbText; Applies; Thread t = null; String [] textLine = new string [4]; Public wallboard () {setUndecorated (true); SetExtendedState (6); . GetContentPane () setBackground (Color.BLACK); GetContentPane () SetCursor (Toolkit.getDefaultToolkit (). CreateCustomCursor (new BufferedImage (16, 16, 2), new point (0, 0), blank)); SetVisible (true); This.WbText = new JLabel ("0123456789012345", 0); This.WbText.setFont (new font ("Monospaced", 1, getWidth () * 18/160)); This.WbText.setHorizontalTextPosition (0); This.WbText.setVerticalTextPosition (0); Add (this.WbText); AddWindowListener (new wardboard (this)); This.t = new thread (this); This.t.start (); }   
 Can anyone help me? What am i doing wrong  
 Many thanks for your input.   
 
 
 It looks like your constructor does not have any logic:  
  Public Wallboard () {setUndecorated (true); SetExtendedState (6); ...   
 and then try calling it using this code as  this  asn logic:  
  addWindowListener (new Wardboard (it));   
  inside the new wallboard (this)  addWindowsListener ()  instead of  WindowListener  apply something else Should>. Try it instead:  
  addWindowListener (new windolister () {});

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...
