possible duplicate: can declare variables of different types in initialization of loop? i'd have loop in c++ constructs 2 different kinds of vector iterator in initialisation. here rough idea of like: std::vector<double> dubvec; std::vector<int> intvec; double result = 0; dubvec.push_back(3.14); intvec.push_back(1); typedef std::vector<int>::iterator intiter; typedef std::vector<double>::iterator dubiter; (intiter = intvec.begin(), dubiter j = dubvec.begin(); != intvec.end(); ++i, ++j) { result += (*i) * (*j); } anyone know standard in situation? can't use vector of double intvec because i'm looking general solution. [i.e. might have function f takes int double , calculate f(*i) * (*j)] you declare std::pair first , second iterator types: for (std::pair<intiter, dubiter> i(intvec.begin(), dubvec.begin()); i.first != intvec.end() /* && i.second != dubvec.end() */; ++i.first, ++i.second

how compilers optimizes theese 4 types of function definitions. there optimization done in sense of argument passing? int check_collision(const sdl_rect const *a,const sdl_rect const *b) { ... } int check_collision(sdl_rect const *a,sdl_rect const *b) { ... } int check_collision(const sdl_rect *a, sdl_rect const *b) { ... } int check_collision(sdl_rect *a, sdl_rect *b) { ... } and if matters, think preferable way of passing read arguments function in cases these argument might inefficent copy when calling funcion? use const in of these cases indicate purpose of usage more , writing more readable code, modern day compilers efficient , smart enough apply required optimization's whether pass function argument const or not. in short, use const in case readability & preventing usage errors, & not compiler optimization, compiler smart enough take care of that.

i've written own grid inherits datagridview class , has custom properties , columns. like : public class foo : datagridview { private system.windows.forms.datagridviewtextboxcolumn c1; public foo() { initializeclass(); } void initializeclass() { this.autogeneratecolumns = false; c1 = new datagridviewtextboxcolumn(); this.c1.datapropertyname = "c1"; this.c1.headertext = "column 1"; this.c1.name = "c1"; } } the program runs well, visual studio creating mess code! in initializecomponent() vistual studio creates again datagridviewcolumns properties :s is there way avoid behavior. thnks! update : autogeneratecolumns set false you either create columns @ runtime, think checking system.componentmodel.licensemanager.usagemode works, or hide columns property designerserializationvisibility attribute.

whats cleanest way perform pointer arithmetic in c++? trying add n bytes address. int *foo; foo = static_cast<int*> (static_cast<unsigned int>(foo) + sizeof(t)) later recast , use foo differently char* somestr = reinterpret_cast<char*>(foo) is enough? understand pointer implementation dosent guarantee pointers ( char* , int* ) implemented of same size. not sure if int* (should foo* ) , using unsigned int math cleanest solution. also, has work on both 32 , 64 bit. nevermind why im doing this. not unusual though. run issue anytime youre working stream (or bytepool) of data interpreted dynamically different types. the cleanest way of doing pointer arithmetic not via numbers of bytes, typed. don’t treat int array else, offset directly: int* next = foo + n; or: int* next = &foo[n]; both superior casting solution. in cases work on byte buffer, use char* , not (never!) int* . is, char* buffer = get_the_buffer(); // pointer arithmeti

this question has answer here: regexp performance (compare “like” , “=”) 3 answers select data test col regexp "asdf_[0-9]+" limit 1 ...1 row in set (1 min 43.12 sec) select data test col "asdf_%" limit 1 ...1 row in set (0.01 sec) regexp can give me exact result, have filter data if use like sql. there way improve? btw: test has 2 million rows , grow up. try changing regexp string "^asdf_[0-9]+" . like anchored (ie like 'asdf_%' says "a string starting asdf_"), whereas regexp not ( regexp 'asdf_[0-9]+' looks anywhere within string). note doing regexp 'asdf_[0-9]+' saying like '%asdf_%' . i think regexp still bit slower like , start of line anchor speed up.

i have json object named data below and have function denomination in string below test name of function call , pass json object data. here test function: test = function (data) { alert('i test function'); } i try: eval(func(data)); it doesn't work. any idea? thanks. while eval() 1 possible solution, awful. instead, interrogate window find function want , run there: function test() { alert("test") } var func = $("#confirm-remove").data("success"); var data = {}; // object var fn = window[func]; if (typeof fn === 'function') { fn(data); } example fiddle this assumes function has global scope.

assume have process pid 1234 running in background under user a. if run following program user a, succeeds. if run user b, fails open: permission denied . this makes sense, environ file owned user , has read permission a. if make program set-user-id user , run user b, fails read: permission denied . doesn't seem happen regular file having same permissions. doesn't happen if root. any ideas why? there other way environment of process works around issue? #include <stdlib.h> #include <fcntl.h> #include <unistd.h> #include <stdio.h> int main(int argc, const char *argv[]) { unsigned char ch = 0; int fd = -1; int read_result = -1; setresuid(geteuid(), geteuid(), geteuid()); fd = open("/proc/1234/environ", o_rdonly); if (-1 == fd) { perror("open"); return exit_failure; } read_result = read(fd, &ch, 1); if (-1 == read_result) { perror("read");

i realize may duplicate question, such as, why use java.io.console? . however, wanted more detailed answer (pros/cons, applications, more). forgive me if misunderstanding this. ran program using eclipse , received error message "no console", let go , ran via terminal instead. however, little unclear why console object doing (i think it's because returns null, wanted more detailed answer). various reads, seems various ides such netbeans , eclipse haven't "implemented" properly. leads me question, , since first time seeing java.io.console , why want use on standard streams? examples applications using console appreciated , preferred! programs written interactive shells in mind provide lot of conveniences command line users tab completion history tracking password input secure against shoulder surfers colored , formatted output using preferred pager paging text console allows java programs invoked via command line present user-exper

so im trying figure out best way render 3d model in opengl when of textures applied have alpha channels. when have depth buffer enabled, , start drawing triangles in 3d model, if draws triangle in front of triangle in model, not render triangle when gets it. problem when front triangle has alpha transparency, , should able seen through triangle behind it, triangle behind still not rendered. disabling depth buffer eliminates problem, creates obvious issue if triangle opaque, still render triangles behind on top if rendered after. for example, trying render pine tree cones stacked on top of each other have transparent base. following picture shows problem arises when depth buffer enabled: you can see how can still see outline of transparent triangles. the next picture shows looks when depth buffer disabled. here can see how of triangles on of tree being rendered in front of rest of tree. any ideas how address issue, , render pine tree properly? p.s. using shaders

please need in how bind jqgrid asmx webservice c# , found topics in how convert asmx webservice json it's not clear me regards first of should define webmethod provide data jqgrid. if plan implement server side sorting , paging webmethod should have @ least following parameters public jqgriddata testmethod (int page, int rows, string sidx, string sord) where jqgriddata class defined example like public class tablerow { public int id { get; set; } public list<string> cell { get; set; } } public class jqgriddata { public int total { get; set; } public int page { get; set; } public int records { get; set; } public list<tablerow> rows { get; set; } } there other different options how 1 can fill grid, it's first important understand @ least 1 way. it's important, return json data web method you don't need convert returned data manually json . need return object data , asmx web service serialize object xml or json
