c++ - Using boost::mutex - implicitly deleted error (because the default definition would be ill-formed) -

-

मेरे पास क्लास दिखता है जैसा कि .h फ़ाइल में है (हैडर) 

  #include & lt; boost / thread.hpp & gt; क्लास मायक्लास {निजी: बढ़ावा :: माइटेक्स बीपीयूएमएमटीएक्स_; // ... अन्य वार्स सार्वजनिक: // सार्वजनिक वार्स और विधियां}

मुझे बनाने / संकलन करने की कोशिश करने में निम्न त्रुटि मिलती है। 

  MyClass H: 38: 7: नोट: 'MyClass :: MyClass (const MyClass & amp;)' को निहित रूप से हटा दिया जाता है क्योंकि डिफ़ॉल्ट परिभाषा बीमार रूप से बन जाएगी: MyClass.h: 38: 7: त्रुटि: हटाए गए फ़ंक्शन का उपयोग 'boost :: Mutex :: mutex (const boost :: mutex & amp;) '

मैं अभी भी cpp फाइल में mutex का उपयोग नहीं करता। जब मैं boost :: mutex लाइन पर टिप्पणी करता हूं तो यह ठीक बनाता है क्या हो रहा है?

कंपाइलर द्वारा उत्पन्न डिफ़ॉल्ट प्रतिलिपि कंट्रोलर सभी डेटा सदस्यों को डिफ़ॉल्ट रूप से प्रतिलिपि बनाता है boost :: mutex का आपका उपयोग त्रुटि को फेंकता है क्योंकि म्यूटक्स कॉपी करने योग्य नहीं है।

आप अपनी खुद की कॉपी कन्स्ट्रक्टर लिख सकते हैं जो म्यूट एक्स की प्रतिलिपि करने का प्रयास नहीं करता है MyClass के लिए प्रतिलिपि कन्स्ट्रक्टर हटाएं। 

  #include & lt; boost / thread.hpp & gt; क्लास मायक्लास {निजी: बढ़ावा :: माइटेक्स बीपीयूएमएमटीएक्स_; // ... अन्य वार्स सार्वजनिक: // सार्वजनिक वार्स और विधियों MyClass (const MyClass & amp;) = हटाएं; }

c# - Highlight all words containing a letter in a richtextbox -

-
How do I highlight all the words in a letter in a rich text box? If I want to expose the words that contain the letters "a", such as a hat or candle word, both words are highlighted, I am using C # on Winform. Private Zero Button 208_Click (Object Sender, EventArgs E) {HighlightFrage (Rich Textbox 1, "A", Color. Yellow); } It exposes all the words with a word "a", but I'm not sure how to highlight the length of the spaces. Thank you. You can use the method to find incidents of sub-location. Then, use the property to change the colors back to Highlight colors for each event. int len ​​= richTextBox.TextLength; Int index = 0; String textconfind = "A"; // This will highlight the text you are viewing (index & lt; len) {richTextBox.Find (textToFind, index, len, RichTextBoxFinds.None); RichTextBox.SelectionBackColor = Color.Yellow; Index = rich textbox. Lesson Index (texttofind, index) + textaophind Langeline; } If you want...

Do you know about a problem due to Admob not being able to click on interstitial ads and therefore on Nexus 5 devices Have not brought any revenue? Fact: It does not have intermediate ads - some clickable, but mostly no . It comes with the old standalone Google Admob SDK and with the new Google Play Services SDK. It is on Nexus 5 with Android 4.4.2 , but it is possible that other devices are also affected. This happens in many programs in the Google Play Store - I'm not only with my application. For example, you can not Galaxy Nexus (Nexus 3), Galaxy S, on the HTC One. Below is a screenshot that opens the small info button in the clickable below the ad and OK, the Close X button also looks working properly , Though clicking on the ad does not happen - like it does not exist or something on it. Do you know of any solutions or possible solutions to the problem? Thanks! --- Update - - This activity declaration is: & amp; Activity Activity:...

java - MigLayout - selective component fill -

I am trying to add a JTabbedPane to a panel, as well as for control I am using Migrates with the following buttons. However, I can not even get the JTabbedPane to fill without the buttons when they are not needed. The following SSCCE: public static zero main (string [] args) {jpn panel = new zpinal (new megallout (new lc.) Filling ())) ; Panel.add (new pocket ("+"); Panel.add (new pocket ("-"), "wrap"); Panel.ed (new zetaabbedpan (), "duration, increase"); Jeffre Frame = New Gefram (); Frame.add (panel); Frame.setSize (new dimension (300, 500)); Frame.setLocationRelativeTo (zero); Frame.setVisible (true); Frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); } This creates a panel that looks like this: However, if I lack layout ( JPanel panel = new JPanel (new MigLayout)); ), looks like: If you do not want to apply a barrier to all the cells, do not say the layout ;-), instead, use the column and row barr...
