ios8 - Swift: array of dictionaries has count of 1 after initialization but should have 0 -

-

इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 4 जवाब 
  var व्यक्ति = [शब्दकोश & lt; स्ट्रिंग, स्ट्रिंग & gt; ()] println (persons.count)

प्रिंट 1 । मैं देखता हूं कि सरणी के भीतर एक खाली डिक्शनरी है, जब इसे आरम्भ किया जाता है, लेकिन उस से बचने और 1 के बजाय 0 तत्व होने का कोई तरीका है? बाद में मुझे करने में सक्षम होना चाहिए: 

  persons.append (["प्रथम नाम": "फू", "अंतिम नाम": "बार"])
< P> कोई भी विचार?

इसका उपयोग करके: 

  [शब्दकोश & lt ; स्ट्रिंग, स्ट्रिंग & gt; ()]

आप एक तत्व dictionary & lt; स्ट्रिंग, स्ट्रिंग & gt; ()

के साथ एक सरणी बना रहे हैं सही तरीके से वर्ग कोष्ठक के बाद कोष्ठक को स्थानांतरित करना है: 

  [शब्दकोश & lt; स्ट्रिंग, स्ट्रिंग & gt;] ()

यह प्रकार की एक सरणी को घोषित करता है < कोड> शब्दकोश & lt; स्ट्रिंग, स्ट्रिंग & gt; , और इसे तत्काल।

इसे बनाने का समतुल्य तरीका है: 

  ऐरे & lt; शब्दकोश & lt; स्ट्रिंग, स्ट्रिंग & gt; & gt; ; ()

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. ...
