powershell - How can I count running EC2 Instances? -

-

I use PowerShell to calculate the number of running EC2 example on AWS, looking for a very basic script I am here. I have found many ways, but for some reason when I try them, I do not get the results.

The closest is: 

  $ instancestate = (get-ec2instance) .instances.state.name $ instancestate

which : 

  Stopped stopped stopping

(this list is released for approximately 80 instances)

I want to make a reaction that calculates the running people.

I'm not sure about other people, but I clearly have my ec2 filter in the variable I like to specify, and then Get-EC2Instance . This makes it easy to work with filters if you have to filter in many situations

Here are examples of your work, in which I have 6 running examples: 

  #FilterPsC: \ & gt; $ FilterRunning = New Object Amazon AC 2 Modell. Filter-property @ {name = "instance-state-name"; Value = "Running"} # Force output of Get-EC2 instance in a collection. PS: \ & gt; $ Running instances = @ (gate-EC 2 instance-filter $ filtering) Count the # running examples (more literally, count the collection iterative) PSC: \ & gt; $ Running instances. Number 6

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. ...
