c# - Change color of certain chart points -

-

मुझे एक चार्ट में रंग बदलने में समस्या है निम्न कोड: 

  चार्ट 1। श्रृंखला ["टेस्ट"]। रंग = रंग। Int start = array1.लांबी; (Ii = 0; i & lt; chart1.Series ["टेस्ट"]। अंक.काउंट; i ++) {यदि (i & gt; = प्रारंभ) chart1.Series ["टेस्ट"]। अंक [मैं]। रंग = हरा रंग करें; चार्ट 1। श्रृंखला ["टेस्ट"]। अंक.एडीएक्सआई (एक्स_एक्सिस [आई], वाई_एक्सिस [आई]); } चार्ट 1। श्रृंखला ["टेस्ट"]। अंक। डेटाबंड XY (x_axis, y_axis); चार्ट 1। श्रृंखला ["टेस्ट"]। चार्ट टाइप = सीरिजचार्ट टाइप। स्पलाइन;

इस मामले में: मेरे पास दो सरणियां हैं- एक्स-अक्ष के लिए एक और y- अक्ष के लिए एक है। मान लीजिए कि उनके पास लंबाई 32 है। मेरे पास 12 की लंबाई के साथ एक अन्य सरणी (महत्वपूर्ण नहीं) है। अब मैं चाहता हूं कि मेरा ग्राफ 12 वीं बिंदु के बाद रंग बदलता है। मैं उसे कैसे कर सकता हूँ? उपरोक्त कोड काम नहीं करता है ग्राफ़ एक रंग में रहता है।

आप प्रत्येक डेटा के लिए लूप दोहराकर कुछ डेटा बिंदुओं के लिए रंग बदल सकते हैं आपके डेटा को बाध्य करने के बाद डेटा बिंदु। 

  अंक अंक = (Microsoft.Office.Interop.Excel.Points) series.Points (Type.Missing); Foreach (अंक में प्वाइंट पीटी) {यदि (आपकी कंडीशन) {pt.Border.Color = (int) XlRgbColor.rgbDarkOrange; Pt.MarkerBackgroundColor = (int) XlRgbColor.rgbDarkOrange; Pt.MarkerForegroundColor = (int) XlRgbColor.rgbDarkOrange; }}

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. ...
