there main page , there links on page. when individual links clicked, supposed load contents link loads inside div tag of main page. example: mainpage.htm <html> ... <body> ... <div id="maincontent"> </div> ... <a href='link1.htm'>link 1 </a> ... </html> link1.htm <script src="main.js">... <div> other contents here </div> when user clicks on link 1, browser doesn't go page, instead ajax used fetch linked document , load inside #maincontent . but, problem linked page has table , there table manipulation codes needed run when first loads. in fact linked document has link separate script , functions supposed run on window.onload . when load linked document using ajax using following approach: maincontent.innerhtml = xhr.responsetext; this not helping run window.onload codes on linked document. are there solutions or workaround type of problem?

i wondering if there build-in way in c++ compare order of 2 bidirectional iterators. example, have sum function calculate sum between 2 iterators in same list: double sum(std::list::const_iterator start, std::list::const_iterator end){ double sum=0; (start;start!=end;start++) sum+=*start; return sum; } then: sum(my_list.begin(),my_list.end()); fine, sum(my_list.end(),my_list.begin()); cause runtime error. i thinking putting if (start>end) return 0; prevent error. seems cannot compare iterators this. you should read introduction stl explains various refinements of iterator concept. only randomaccessiterators support comparison < because not efficient operation non-randomaccessiterators. the way tell if bidirectionaliterator i less-than another, j , incrementing i 1 step @ time , seeing if ever reach j , never happen if j not reachable i , , error if i not incrementable, e.g. because past-the-end iterator range. alter

i followed : uilabel , nslinkattributename: link not clickable , uitextview link clickable, when click it, safari doesn't open no avail. i have : uitextview.attributedtext = ... attributed string "http://google.com" ... "links detection", "selectable" , "user interaction enabled" enabled. "editable" disabled. i implemented uitextviewdelegate - (bool)textview:(uitextview *)textview shouldinteractwithurl:(nsurl *)url inrange:(nsrange)characterrange { return yes; } however, link appears blue when click, nothing happens. i had same issue. nothing did help. the problem was, added uitextview scrollview , used sizetofit . for example: had view.frame (0,0,320,440). , scrollview contentsize (0,0,320,1000) , links in view.frame works when scroll down - not. than tried check view selecting when scroll down , tap on uitextview. added uitapgesturerecognizers , find out when tap in bounds of self.view fra

i have created test sharepoint server close our production server possible. production sharepoint databases backed , restored our test server. 3 main web.configs (central admin, main site, security token service application) modified include our custom app settings. the site comes fine, logging in using both ad , our custom fba membership provider works well. certain pages visible in site libraries through view site content , using sharepoint designer sharepoint says page(s) not found if try view them or check them in. not pages not available. if delete bad page , replace copy our production application, displays fine. i've found , tried possible solutions such restarting search query , site settings service , checking alternate access mapping. found possible solution has go component services , modify security relative osearch14 property. not able modify since right clicking on property did not pop menu options. continue this. any ideas? appreciate help. thanks.

i implementing binary search in c++. here code: #include <iostream> #include <vector> #include <algorithm> using namespace std; int bs(vector<int> a, int val) { int l =0, r = a.size()-1; while(l<=r) // significance of == { int mid = l + (r-l)/2; if(a[mid]==val) return mid; if(a[mid]>val) { r = mid-1; continue; } else { l = mid + 1 ; } } return l; // deliberately returning } int main() { vector<int> = {1,3}; cout << bs(a,1) <<endl; return 0; } question 1 in implementations, see people use while(l<r) while in use while(l<=r) is there conceptual difference between preferring 1 way ? possible sources of error if don't use == ? question 2 in case element not found, l guaranteed position in element inserted list still remains sorted ? valid while using equal or not using equal ? it depend

does know how implement composerbar , keyboard appearing in facebook messenger? after scrolling tableview up, keyboard appears bottom smoothly , without jumps . in similar implementation works this: after scrolling up, when tableview bottom offset < 0, composerbar's input text field become first responder , keyboard jumps finger. yes, use uiscrollviewkeyboarddismissmodeinteractive . how facebook implement smooth animation? edit: try explain how works in facebook messenger, step step. i have inputaccessoryview on viewcontroller (tableviewcontroller). start scroll tv (pic 1) then, if bottom inset become more value (for example 10) (pic 2), set firstresponder inputtextfield (pic 3) so, in common case, 'uiscrollviewkeyboarddismissmodeinteractive', keyboard jumps finger position (pic 4) but! in facebook messenger keyboard drags bottom distance equal distance traveled finger. (pic 5) so, facebook messenger somehow control keyboard moving. question
