c# - WPF Thumb drag behaviour wrong -

-

I created a thumb in WPF. 

  Private Zero Thumb_DragDelta (Object Sender, System.Windows Control.Premitives.DragDelTeventEurges e) {MyValue = e.VerticalChange; }   
 This works fine, however, when my button is clicked again, the value starts at the point where I clicked (0). I need to click and drag to change the relative value of the original. So I tried to do this:  
  Private Zero Thumb_DragDelta (Object Sender, System.Windows.Controls.Primitives.DragDeltaEventArgs ) {MyValue + = e.VerticalChange; }   
 This works, but when I pull down and then go up, the value decreases, even if I take the mouse back up. The only thing when moving the mouse up (the value increases), and then move the mouse back down (the value keeps increasing).   
 
 
 How it works:  
  double minLeft = double MaxValue; Double hntop = double. Maxwell; Double left = canvas. Gadget left (item); Double top = canvas.Tet (item); MinLeft = Double. ISNAN (left)? 0: Math (Left, minorleaf); MinTop = Double. ISNAN (Top)? 0: Math (Top, Mintop); Double delhoraciontal = monastery.max (-min lift, e. Horizontal change); Double Delta Vatic = Meth. Max (-Mantop, E. Vertical Change);   
 Replace your container control with the canvas.

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...
