html - Perl code to check progress bar level and display through jQuery -

-

I have a Perl code that gets the percentage of usage which is 30% I have written HTML, which That's the value in class Progress Bar and Pearl as $ usage. And I've used that category to show the progress bar in a page in jQuery. But this is not working 

  & lt; Link rel = "stylesheet" href = "// code.jquery.com/ui/1.11.2/themes/smoothness/jquery-ui.css"> & Lt; Script src = "// code.jquery.com/jquery-1.10.2.js"></script> & Lt; Script src = "// code.jquery.com/ui/1.11.2/jquery-ui.js"></script> & Lt; Script & gt; $ (Function () {$ ("#progressbar"). Programbar ("value");}); & Lt; / Script & gt; & Lt; Div class = "progress bar" value = & lt;% $ usage_percentage% & gt; & Lt; / Div & gt; & Lt;% Perl & gt; My $ usage_percentage = 30; & Lt; /% Pearl & gt;

Please help in advance thanks.

Some things are wrong in your code. First, you use the ID selector $ ("# progressbar") , but your HTML does not have any such id Change 

  & lt; Div class = "progressbar" ... & gt;

to 

  & lt; Div id = "progressbar" ... & gt;   
 Second,  value   & lt; Div & gt;  is not a valid feature for the tag, when the data from HTML to HTML / JavaScript is passing from Perl, then I recommend using it, for example 
 
  and lt; Div id = "progressbar" data-percent-used = "30" & gt; & Lt; / Div & gt;  
 
 provides one to access the jQuery  data - *  attributes: 
 
  Var percent usage = $ ("#progressbar"). Data ("percent-usage"); // 30  
 
 Note that you can use the  data-*  attributes in HTML4, they are only considered as regular attributes. 
 
 Third, you are calling a method for the progress bar, do not set it

to 

  $ (" #progressbar ") .progressbar (" value ");  
  $ ("#progressbar") .progressbar ({value: 30});  
   
  
  
  
  
  & Lt; Script & gt; $ (Function () {var container = $ ("#progressbar"); container.progressbar ({value: container.data ("percent-usage"}}}}); & lt; / script & gt; & lt; Div id = "progressbar" data-percent-used = "& lt;% $ usage_percentage%>" & gt; & lt; / div & gt;
< / Html>

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
