i'm using resharper 7.1 , stylecop 4.7 (with visual studio 2012). default resharper loads stylecop rules inspection , off them action taken "warning", though in settings.stylecop file of rules disabled. if stylecop rule disabled resharper "do not show" (because of course, not default rules make sense time). i know can done manually in resharper - options - inspection severity, choosing action take each rule. there way automatically? is, make resharper not warn rule being broken if it's disabled in stylecop.settings? it makes sense automatically, because want define set of mandatory rules team apply, , redundant have each engineer manually fix action taken each existing rule (since lot). thanks in advance, mihai it seems there no way this, although, possible configure rules manually in resharper options , export options (via manage -> export file) , can imported on other machines.

this based on earlier question asked . sending octet of 0 bits linux linux machine such on socket const char null_data(0); send(newsockfd,&null_data,1,0); my question same when sending windows machine (64 bits) ? or have change code ? the trick here use uint*_t data types, insofar feasible: #include <cstdint> /* ... */ #if !defined(__win64) // *nix variant typedef int socket_fd_t; #else // winxx socket descriptor data type. typedef socket socket_fd_t; #endif void send_0_byte(socket_fd_t newsockfd) { uint8_t zero_byte(0); send(newsockfd, &zero_byte, 1, 0); } you want add error checking code, include correct platform socket header. uint8_t 8-bit quantity (octet) definition, meets requirement , avoids potential char size issues. on receiver side, want recv uint8_t buffer.

i have grid made of ios buttons (think sudoku). assigned each button have aspect ratio 1:1. further ensure equality, have made each button have width = height constraint set. however, when @ buttons, of them have 44x45, while others have 44x44 (as expected). is there constraint i'm missing or there workaround can guarantee buttons perfect squares. this happening because have other constraints affecting views too. eg. might have put these in container view , specified container views width or made container view's width equal width of screen. now when these square view fill container view, there space left eg 7 points. autolayout adds these 7 points making of squares wider 1 point. this can fixed providing correct constraints container view.
