postgresql - query with not equal doesn't work -

-

This is a dumb question, but still, I am trying to write an equivalent where the document documents with PostGrussCl The icon & lt; & Gt; or ! = Both always get 0 results where an integer is on the field 

  Select user from user where user & lt; & Gt; 2; Choose UserAdd from Usartep! = 2;

The table looks like this: 

  User ID is not a major primary key to create a user, name VARCHAR (50) No, phone number VARCHAR (20 ) Is not unique, UserType INTEGER NULL);  Note:    Note:  Select the user from the following Executive Job and Return Results  
  User where the user & lt; 2 or Usery & gt; 2;  
 
 I was just thinking that someone is facing the same problem?

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. ...
