Simplifying the variable input in SAS -

-

My data has 90 variables, I want to do the following in the SAS.

Here is my SAS code: 

  data testing; Length ID class sex $ 30; Input id $ 1 class $ 4-6 sex $ 8 $ 10; Leaves; 1 3F Y2 sec F Y3 2FN 4 1 MN 5 3FN 6 2MM; Run; Data item 2; Set test; Length 8; Length items $ 8; Tid = _n_; Item = class; Output; Item = sex; Output; Item = hiccup; Output; Keep items; Run; Do I have 9 0 variables to input such data? There should be a very long list. I want to simplify it.   
 
 
 You can use an ARRAY or Alternatively a PROC TRANSPOSE.  
 The following is Untested, because you have not given an example of your input dataset.  
  data items; ARRAY VARS {*} VAR1-VAR90; Change the set; DO I = LBOUND (Wars) to HBOUUND (Wars); ITEM = VARS {I}; Output; End; Run;  
 
 or 
 
  PROC TRANSPOSE data = test = want out; By ID; Class class - servile; Run;  
 
 In the future it will be best that you can supply your input and desired output.

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. ...
