java - Insert to jTable date from MySQL -

-

Hello I'm jTable and I need to date jTable for this SQL query. But I can not include the jTable date from the rank, the second date is correct, but jTable 6 columns are empty. 

  try {class.forName ("com.mysql.jdbc.Driver"); Connection thief = (connection) DriverManager.getConnection ("JDBC: mysql: // local host: 3306 / db_mafia useUnicode = true & characterEncoding = UTF8", "root", "qwerty"); Statement ST2 = con.createStatement (); ResultSet result2 = st2.executeQuery (select ". T *, @rank: = @Rank + as the post \ 1 n" + "(select id_user, (Select from users the nickname where id_user = id ), (Where name selects id_user = id), (select the nickname from users where id_user = id), by SUM (digit) as the number \ n by the number "n" + by the ASC by the id_user command group ) T "); While (result2.next ()) {(DefaultTableModel) jTable1.getModel ()). AddRow (new object [] {result2.getString (1), result2.getString (2), result2.getString (3), result2.getString (4), result2.getString (5), result 2.getstring (6)} );} Result2 .Submit (); } Hold (exception e) {JOptionPane.showMessageDialog (null, e); E.printStackTrace (); System.exit (1); }

And before the query I want to execute it but I do not know where to put it?: 

  SET @ank = 0;

Select with rank 0 before the rank var: st2.executeUpdate ( "SET @ rank = 0"); 

  Try {class.forName ("com.mysql.jdbc.Driver"); Connection thief = (connection) DriverManager.getConnection ("JDBC: mysql: // local host: 3306 / db_mafia useUnicode = true & characterEncoding = UTF8", "root", "qwerty"); Description st2 = con.createStatement (); St2.executeUpdate ("SET @ank = 0"); Results result 2 = st2.executeQuery ("select t. *, Rank = \ ranks = 1 \ n" + "from (select id_user, (by selecting the user name where id_user = id), (users Selection Number from where id_user = id), (Select the nickname from users where id_user = id), by SUM (digit), by number \ n "+" by id ASUS by the ASC command group) T); While (result2.next ()) {(DefaultTableModel) jTable1.getModel ()). AddRow (New Object [] {result2.getString (1), result2.getString (2), result2.getString (3), Results 2 GetString (4), Results 2 .getString (5), Results 2 .getString (6) }); } Result2.close (); } Hold (exception e) {JOptionPane.showMessageDialog (null, e); E.printStackTrace (); System.exit (1); }

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. ...
