java - Replacing a class file inside a folder in a jar file -

-

I have a jar file in C: \ (xx.jar). I need to change a class file (path: com \ sample \ folder \ xfile.class) inside xx.jar with a square file (yfile.class) that is C:.

Please help me command to change a class file in jar with another class file out of jars I point to the directory structure.

I tried,

jar uf c: \ xx.jar C: \ yfile.class

The above command creates a new folder C: \ xx In .jar and yfile.class comes inside C. But I want to put the file inside xx.jar inside com.ample.folder

Please help please thank in advance!

You really can not have jars to actually package a ready folder. I think this is the reason that with Mare, etc. everything creates a build folder that ends in jar / war / ear file. 

  jar uf C: \ xx.jar C: \ Yfile.class

Really adding the file to the archive Some-C can use the instructions, but it's about it. Let's say that you have a dior in myfile.class C: \ classes and you can call it jar from the folder 

  jar uf c: \ xx.jar -C .. classes \ file.class < / Code>

The folder is going to add the square to the jar, in which the file is myclass.class.

Kind regards

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. ...
