How to get help on specific methods in the interactive shell of MongoDB? -

-

In the interactive shell in MongoDB, db.help () list (all) methods that can The (current) database can be used for reference.

But how do I method db.logout () ?

Calling db can get information about using & Lt; CollectionName & gt; .help () list (selected) is available for archiving.

But how can I do the method db & Lt; CollectionName & gt; .logout () ?

Why db & Lt; CollectionName & gt; .exists () not listed?

calling db & Lt; CollectionName & gt; (). Help () list (all) cursor-function.

But I do not like the method db & Lt; CollectionName & gt; .find () Sort () ?

If you just need to review limited details about the use of a fixed By method, you can type the method without brackets and enter the code to get the javascript For example, type db.c.find and enter (no archive name is available). If you need to get more details about the use of a certain method, then you should read them.

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).

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. ...
