dependency properties - How WPF DependencyProperty pickup the key to distinguish each instance of an object and seek the values of the DependencyProperty? -

-

Many articles from Google have said that the dependency property is stable because it contains a key to maintain the value of each instance. Value is the object

But the problem is that, if we call GetValue / SetValue against deprecated property, then how it recognizes each instance and generates the key so that the values ​​are read / saved from the hashtable for different instances What is the active object?

For example: If we create 2 examples of TestDP and then set the value for TestDProperty for both instances, then SetValue recognizes each instance and saves the dependency portion value accordingly to the hash table. is?

I getValue & amp; Code is examined for; Set up the dependency object, but I still can not understand how it separates each example. Code is it.LockUpEntire (DP Global Index) will pick up the Entry Index but I'm not sure how the Global Index has been prepared to distinguish each instance of the object. 

  Public class TestDp: DependencyObject {protected static dependency document DpTest = DependencyProperty.Register ("TestDProperty", typef (string), typef (testdp)); Public string TestDProperty {get {var r = (string) GetValue (dpTest); Return r; } Set {Set Value (DPTist, Value); The GetValue of DependencyObject will call GetValueEntry and will consume EntryIndex which you have mentioned 'However, it does not generate any key based on informational information.

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. ...
