c# - Why the cpu performance counter kept reporting 0% cpu usage? -


यहाँ मेरा कोड स्निपेट है: 

  PerformanceCounter cpuload = नया PerformanceCounter (); Cpuload.CategoryName = "प्रोसेसर"; Cpuload.CounterName = "% प्रोसेसर समय"; Cpuload.InstanceName = "_Total"; कंसोल.प्रकाश रेखा (cpuload.NextValue () + "%");

लेकिन आउटपुट हमेशा 0% है, जबकि cpuload.RawValue 736861484375 जैसा है या ऐसा है, क्या NextValue () हुआ है? मेरा सीपीयू स्पष्ट रूप से 0% उपयोग में है।

धन्यवाद दोस्तों ~ 8 ^)

उस काउंटर की पहली यात्रा हमेशा 0 होगी, क्योंकि उसके पास अंतिम मान से तुलना करने के लिए कुछ नहीं है इसे आज़माएं: 

  var cpuload = नया प्रदर्शनकॉन्टर ("प्रोसेसर", "% प्रोसेसर समय", "_Total"); कंसोल.प्रकाश रेखा (cpuload.NextValue () + "%"); कंसोल.प्रकाश रेखा (cpuload.NextValue () + "%"); कंसोल.प्रकाश रेखा (cpuload.NextValue () + "%"); कंसोल.प्रकाश रेखा (cpuload.NextValue () + "%"); कंसोल.प्रकाश रेखा (cpuload.NextValue () + "%");

तब आपको कुछ डेटा बाहर आना चाहिए। यह एक निरंतर ग्राफ़ या अपडेट किए गए परिदृश्य में देखा जाता है ... इसलिए आप अक्सर इस समस्या में नहीं आते हैं।

यहाँ है:

विधि अगले वेल्यू () हमेशा पहली कॉल पर 0 मान देता है। इसलिए आपको इस विधि को दूसरी बार कॉल करना होगा।

.net - C# List<T>.Find(x=>x.Rectangle.Contains(Point)) FAIL -

For my life, I can not understand why this code generates the following output ... I think there is a bug or something while using the list and lambda, if type one rectangle exposes the property and you use the included method of rectangle object ... and the clear statement proves true while Find list method fails .... Onway Code Public Gridskeyr Warldtokapadsb (Point location) {location = _Map.WorldToClient (location); Gridsquare gs = this.find (x => x.Rectangle.Contains (location)); GridSquare KP = G.Find (X => X. laxative canteen (location)); & Lt; GridSquare & gt; List = kp.FindAll (x => x.Rectangle.Contains (location)); U.dp (list.Count); Gridskare sub = KP.Fid (X => X. laxative canteen (location)); If (sub == faucet) {u.dp (place to look for "location"); U.dp ("The location found in the grid category" + GS toaster ()); U.dp ("Grid Square Bounds" + gs.Rectangle.ToString ()); U.dp ("location found in keypad" +...

I am making my own UITableViewCells with a gradient background. I have worked all the logic and drawing, but the one that I want to fix is ​​"chunky" around the corners of my custom cell: If you have corners, you See what I'm talking about.

c++ - QtQuick: QQmlApplicationEngine failed to load component qrc:/main.qml:23 Invalid attached object assignment -

Looking at my thoughts below, am I barking the wrong tree? Or in the information given below, am I misusing the Qt API to get an error in the title? I'm trying to modify the sample to work with the default coefficic project generated from Qt Creator 3.3.0 (OpenSource). Qt 5.4.0 (GCC 4.6.1, 64bit) Based on. The first thing to look at after the code is that I stand by: The sample uses the main.cpp: qmlRegisterType & lt ; Squircle & gt; ("OpenGLUARMM", 1, 0, "Squircle"); QQuickView view; View.setResizeMode (QQuickView :: SizeRootObjectToView); View.setSource (QUrl ("QRC: ///scenegraph/openglunderqml/main.qml")); View.show (); Some name changes in my name. CPP qmlRegisterType & lt; Menuscreen & gt; ("OpenGLUnderQML", 1, 0, "Main Screen"); QQmlApplicationEngine engine; Engine.load (QUrl (QStringLiteral ("QRC: /main.qml"))); I'm not sure that the difference in using QQmlApplicationEngine...
