    यहां मेरा कोड है: < / P> 

      & lt; SCRIPT भाषा = "जावास्क्रिप्ट" & gt; $ (फ़ंक्शन () {$ ("# selectall")। क्लिक करें (फ़ंक्शन () {$ ('। name')। attr ('checked', this.checked);}); $ ("। name") क्लिक करें (फ़ंक्शन () (यदि ($ ("। नाम")। लंबाई == $ ("। नाम: चेक किया हुआ") लंबाई) {$ ("# selectall")। एट्र ("चेक किया गया", "चेक किया गया") ;} और {$ ("# selectall")। RemoveAttr ("चेक");}}};}); & Lt; / स्क्रिप्ट & gt;   
     और फ़ॉर्म के लिए:  
      & lt; td & gt; & lt; इनपुट प्रकार = "चेकबॉक्स" id = "selectall" /> gt; & lt; / td & gt ; & LT; टीडी & gt; नहीं। & Lt; / टीडी & gt; & Lt; td वर्ग = "वेब" चौड़ाई = "400" संरेखित करें = "केंद्र" & gt; नाम & lt; / td & gt; & Lt; td वर्ग = "वेब" चौड़ाई = "240" align = "center" & gt; उपयोगकर्ता नाम & lt; / td & gt;   
     मेरी समस्या यह है, जब मैं चुनिंदा चेकबॉक्स पर क्लिक करता हूं, यह सभी चेकबॉक्स को चेक नहीं करता।   
     
     
     एक नज़र रखना:  
      $ ("# selectall") .क्लिक करें (फ़ंक्शन () {$ ('। नाम')। एट्र ('चेक किया गया', यह। चेक);}); $ ("। नाम")। क्लिक करें (फ़ंक्शन () {if ($ ("। नाम")। लंबाई == $ ("। Name: checked")। लंबाई) {$ ("# selectall")। Attr ( "चेक", "चेक किया गया");} और {$ ("# selectall")। RemoveAttr ("चेक");}}); & Lt; इनपुट प्रकार = "चेकबॉक्स" id = "selectall" / & gt; सभी & lt; तालिका & gt; चुनें & LT; टीआर & gt; & Lt; td & gt; & lt; इनपुट प्रकार = "चेकबॉक्स" id = "1" वर्ग = "नाम" /> gt; & lt; / td & gt; & LT; टीडी & gt; नहीं। & Lt; / टीडी & gt; & Lt; td वर्ग = "वेब" चौड़ाई = "100" संरेखित करें = "केंद्र" & gt; नाम & lt; / td & gt; & Lt; td वर्ग = "वेब" चौड़ाई = "140" संरेखित करें = "केंद्र" & gt; उपयोगकर्ता नाम & lt; / td & gt; & Lt; / टीआर & gt; & LT; टीआर & gt; & Lt; td & gt; & lt; इनपुट प्रकार = "चेकबॉक्स" id = "2" वर्ग = "नाम" /> gt; & lt; / td & gt; & LT; टीडी & gt; नहीं। & Lt; / टीडी & gt; & Lt; td वर्ग = "वेब" चौड़ाई = "100" संरेखित करें = "केंद्र" & gt; नाम & lt; / td & gt; & Lt; td वर्ग = "वेब" चौड़ाई = "140" संरेखित करें = "केंद्र" & gt; उपयोगकर्ता नाम & lt; / td & gt; & Lt; / टीआर & gt; & Lt; / तालिका & gt;

c++ - ERROR: cannot open source file x11\xlib.h -

-
I am using OpenCV 2.4.8 and Visual Studio Express 2012. I have included all environmental variables PATH and additional libraries etc. I get this error when I run the code: Error: source file x11 \ xlib.h p> Can not open I tried in Google but I can not be able to get the proper solution. #include & lt; X11 / Xlib.h & gt; #include & lt; X11 / Xutil.h & gt; You can not just use that code on windows While OpenCV itself is very portable, the code is not clearly above it. Instead of using cv :: imshow (), jujojujo2003 was using the native XWindo call for the pirate.)

c - What are pthread cancelation points used for? -

-
In some cases the respondents say that unless the programmers do not know that they are doing the pthread cancellation points (in many cases) If there are very well, the cancellation points should not be used. My question --- what is the use of pthread cancellation points? [Updated from the comment] Does a cancellation status allow those specific API calls to be canceled? Why not others and others? Does anyone want to use them for something else? Is he a hack to deal with a problem in the kernel, or are they contained in some things that are with posics? Do you want to use the user-level code or only the cancellation point in the API? whether a cancellation point allows to cancel those special API calls is? Stuck with PTHREAD_CANCEL_DEFERRED, this can be the center of confusion. You are thinking about it at the rear side about the Allow system call (the API does not name your name) to cancel the cancellation point, checks the call whether a cancellation reque

c# - Show a huge number of data in DevExpress GridView -

-
With 3000 lines I have a DevExpress grid view and each row has 10 as extensions (this means that when I have 30000 loads in grid load items to load) All data loads It takes a long time to do so, then there is a way to show example 100 lines, and when I use the automatic filter, do I show the lines I want? Example I tried to leave and take (using LINQ), but what I actually see for it Also want to use the automatic filter of the grid. Public Static Binding List & lt; Patient & gt; GetObjectUsingLinq (string sql = "", int skipCount = 0, int lekton = 0) {var gsData = GetDataContext (); Var query = (to choose q.nom q with GS dataApotate order); Return new compulsory list & lt; Patient & gt; (LinqHelper.DoSortPaginate (Query, "" Leave, Techcount) .Oolist ()); } and to call it on the grid listPatient = patients.getObjectUsingLinq (); myGrid.DataSource = listPatient; If you need to display large amounts of records in the grid control,
