i need check weather compiler has correct settings or not , purpose using cpp unit test cases , verifying settings correct or not.compiler settings concerned e.g 64 bit compiler 64 bit code exist , 32 bit compiler 32 bit code exists should not code supposed have 64bit compiler , executed on 32 bit compiler , if happens,a cpp unit test case shall check , fail. there can other condition version of compiler needs , code opened on different compiler version , cppunit test case shall fail. idea if in case of compiler related failure 1 should know , more clearity issue. @ runtime code not executed throwing errors e.g the application unable start correctly (0xc000007b). its because code actualy has executed 64 bit configurations , executed 32 bit configurations in such case there shall test case checking configurations , hence fail , user have ease know actualy went wrong such errors @ runtime quite pain analyze , resolve. so, whole idea make ease in getting knowing runtime error ca...

how can access related menuitem ? has been created on fly, cannot use name in xaml file. private void menuitem_canexecute(object sender, canexecuteroutedeventargs e) { var snd = sender; // main window var orgsource = e.originalsource; // richtextbox; var src = e.source; // usercontrol // think must use command, how? routedcommand routedcommand = e.command routedcommand; } you can pass commanding ui element command binding commandparameter property, like <menuitem ... commandparameter="{binding relativesource={relativesource self}}"/> now can access menuitem parameter property of canexecuteroutedeventargs: private void menuitem_canexecute(object sender, canexecuteroutedeventargs e) { var menuitem = e.parameter menuitem; ... }

hi i'm learning python , i'm facing problem dictionaries: i made dictionary contains shows , number of seasons have all_shows = {'modern family': 3 , 'how met mother': 9 , "modern world" : 12 } and made possible user number of season searching name of show showname = input('<<enter show: >>') season = (all_shows.get(showname)) print (season) the problem number of season returned if user writes exact name of show. i'm trying fix if user write "modern" shows "modern" in title ( if write in lower case) , can select show 1 wants. i looked online , found fuzzywuzzy. think me achieving want? thought using similar show title 1 selected, if wrote " how met mother " result still " 9 " , if wrote " modern " list follow select shows contains "modern" 1 wants. is fuzzywuzzy looking or there other ways that? regular expressions friends. import re all_s...

here header of function: int* matrixmult(const int*ap[], const int* bp[], int* cp[]) and working call of function: matrixmult(ap, bp, cp); why doesn't call work?: matrixmult(ap[0], bp[0], cp[0]); why doesn't call work?: matrixmult(ap[0], bp[0], cp[0]); here, values (first item of array - int ) passed function, while pointers expected: int* matrixmult(const int*ap[], const int* bp[], int* cp[]) this: matrixmult(ap, bp, cp); works because 3 pointers. ap same &ap[0] .

i have mysql query replace string on row below; update users set user_online = user_online - 1, connectedsrv= case when connectedsrv= '1.1.1.1' replace (connectedsrv, '1.1.1.1', '') else replace(connectedsrv, ';1.1.1.1', '') end username='$common_name' however, may use same value multiple times in row ; 1.1.1.1;1.1.1.1;1.1.1.1 once tried execute update sentence , replaces '1.1.1.1' values want delete one. result should be; 1.1.1.1;1.1.1.1 thanks in advance, correct way: normalize schema , ensure every column contains atomic data (first normal form). csv column violation of simple rule. should avoid it. workaround way use simple string manipulation: update users set user_online = user_online - 1, connectedsrv= case when connectedsrv= '1.1.1.1' '' when connectedsrv '%1...
