मैं एक कस्टम लॉगर और मैं एक स्क्रीनशॉट लेने के बाद जो भी करने की कोशिश कर रहा हूं, मैं छवि नाम को लॉग करने के लिए अपने लॉगर फ़ंक्शन को कॉल करना चाहता हूं। जब मैं वादा करता हूं तो यह कक्षा में सभी कार्यों को नहीं देख सकता 

  module.exports = {takeScreenshot: function (driver, filename) {driver.takeScreenshot ()। फिर ( फ़ंक्शन (डेटा) {name = filename} 'ss.png'; var screenshotPath = 'results / screenshots /'; fs.writeFileSync (screenshotPath + name, डेटा, 'base64'); वापसी स्क्रीनशॉट पाथ + नाम;})। फिर (फ़ंक्शन (e) {this.logger (e, "true");}); }, लकड़हारा: फ़ंक्शन (लॉग, स्क्रीनशॉट) {isScreenshot = screenshot || "असत्य"; Var obj = {}; अगर (isScreenshot == "true") {obj [testName.replace (/ / g, '')] = {लॉग्स: "", स्क्रीनशॉट: "& lt; img src = \" "+ + + +" \ "class = \ "परीक्षण-आईएमजी \" / & gt; " }; logger.push (obj); } अन्य {obj [testName.replace (/ / g, '')] = {लॉग्स: "& lt; span class = \" test-log \ "& gt;" + लॉग + "& lt; / span & gt;", स्क्रीनशॉट: ''}; logger.push (obj); }}}

असल में यह लॉगर विधि नहीं देख रहा है मैं क्या खो रहा हूँ? धन्यवाद

आपका यह अलग है।
अधिक जानकारी के लिए पढ़ें के बारे में यह । 

  लेफ्टसॉटसः फ़ंक्शन (चालक, फ़ाइलनाम) {var self = this; Driver.takeScreenshot ()। तब (फ़ंक्शन (डेटा) {name = filename || 'ss.png'; var screenshotPath = 'results / screenshots /'; fs.writeFileSync (screenshotPath + name, डेटा, 'base64'); वापसी ScreenshotPath + name;})। तब (फ़ंक्शन (ई) {self.logger (e, "true");}); },

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. ...
