python - PySide Dialog return values on accept -

-

I am creating a dialog that returns a dictionary to a function, though the need to validate the input before being processed is.

I am using the following code to run the dialog and return the dictionary: 

  if transadd.exec_ (): known = trans.widig.get_views ()   
 A dialog that communicates with a dialog and a widget with a transition.   
  
 
 
 
 
 
 
 
 
 
 
 
 
 . Unknown: self Unknown [key] = self.unknown_trans [key] [1]. Current text () returns self I have an authentication method that is activated when the user clicks on 'OK':  
  def is valid (auto, Dialog): count = 1 incorrect = wrong for the key in itself. Unknown: if self Unknown_tr key [1]. Current text () == "Please select ..." and \ self.gridLayout.itemAtPosition (counting, 3)! = 0: self.gridLayout.addWidget (QtGui.QLabel ("missing answer", dialog), count, 3, 1, 1) incorrect = true self.sizePolicy = Q TGui.QSizePolicy (QtGui.QSizePolicy.Expanding, QtGui.QSizePolicy .Expanding) Count = = 1 If not Errored: Dialog.accept ()   
 Currently all the above mentioned tasks are exactly how I want it to serve me. The problem occurs when the user clicks on the canceled dialog (disapproved ()). This case is not recognized because we are canceling it which is fine. But due to the first part of the code, get_values ​​is still running - that will turn the remaining function and create an incorrect output.  
 So my question is: How do I return a dialog box only when accepting acceptable clicks as opposed to rejecting the user? 
 
 
 In general, if you do not go into a standard way (a top-level modal widget) , You can still use whether the result was accepted or rejected:  
  transadd.widg.result ()

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...
