i'm concerned endianness when comes problem. maybe overthinking have worry about. the input code packet looks like: i've received network packet contains bytes. if know index in byte array (and have valid data) of in_addr is, safe like: uint8_t* addrptr = packet[ip_idx]; struct in_addr addr; memcpy((void*) addr, addrptr, sizeof(in_addr)); is safe regardless of endianness? what in6_addr 16 bytes? thanks. struct in_addr supposed in network byte order, iirc. assuming packet delivered in network byte order, you're go.

i'm doing things said in how prevent user changing selected tab page in tabcontrol? things working fine. validating event of tabpage1 occurs if i've tabpage1 selected , user clicks on tabpage1 itself. , later when user clicks on tabpage2 validating event tabpage1 doesn't fire. what happens if e.cancel in validating event of tabpage1, in above case, when user clicks on tabpage1 mistake having tabpage1 selected, prompt user "do want stay on current tab save data or move current tab?". , if user clicks stay doesn't changes. , when correctly clicks tabpage2, validating event of tabpage1 not firing. i've uploaded sample application here . can run , see behavior understand problem use tabcontrol.selecting event instead. use this: tabcontrol1.selecting += tabcontrol1_selecting; private void tabcontrol1_selecting(object sender, tabcontrolcanceleventargs e) { e.cancel = !(can switch tab); }

i have couple of global variables in servlet. individual servlet sessions read , wrote these variables. used coordinate values posted database important sessions remain in synch. question can use synchronize key words servlets keep different servlet sessions colliding each other @ these global variables? thank you, i'd recommend not doing stuff in servlet class itself. have servlet's doget() etc. call object real work. if delegated class singleton have full control on initialization, state etc. if rely on how app server loads servlet class things can brittle. best let server classload/share servlet whenever feels , not depend on specific behavior.

what point of one-comparison-per-iteration binary search? , can explain how works? there 2 reasons binary search 1 comparison per iteration. less important performance. detecting exact match using 2 comparisons per iteration saves average 1 iteration of loop, whereas (assuming comparisons involve significant work) binary searching 1 comparison per iteration halves work done per iteration. binary searching array of integers, makes little difference either way. expensive comparison, asymptotically performance same, , half-rather-than-minus-one isn't worth pursuing in cases. besides, expensive comparisons coded functions return negative, 0 or positive < , == or > , can both comparisons pretty price of 1 anyway. the important reason binary searches 1 comparison per iteration because can more useful results some-equal-match. main searches can are... first key > goal first key >= goal first key == goal last key < goal last key <= goal last key ...

i want select 10 last messages received or sent different users. for example results must shown that: 1. john1 - last message received 04/17/10 3:12 2. thomy - last message sent 04/16/10 1:26 3. pamela - last message received 04/12/10 3:51 4. freddy - last message received 03/28/10 9:00 5. jack - last message sent 03/20/10 4:53 6. tom - last message received 02/01/10 7:41 ..... table looks like: create table `messages` ( `id` int(11) not null auto_increment, `time` timestamp not null default current_timestamp, `sender` int(11) default null, `receiver` int(11) default null, `content` text ) i think facebook (and iphone) uses solution. when go mail box, have last messages received/sent grouped users (friends). so take example. if have theses messages (they ordered yet): **mike** **tom** **pam** mike mike **john** john pam **steve** **bobby** steve steve bobby only message **** should returned because last messages sent/received user. in fact want last ...

i have simple task in need select rows particular field value of 1 first, value of 2 , other rows value of 0. i using join items member of category. thought performing 3 selects , using union combine results in correct order, wrong :) my sql follows: select * tblcompanycategory inner join tblcompany on tblcompany.idcompany = tblcompanycategory.idcompany tblcompanycategory.idcategory = @category , tblcompany.intpremium = 1 union select * tblcompanycategory inner join tblcompany on tblcompany.idcompany = tblcompanycategory.idcompany tblcompanycategory.idcategory = @category , tblcompany.intpremium = 2 union select * tblcompanycategory inner join tblcompany on tblcompany.idcompany = tblcompanycategory.idcompany tblcompanycategory.idcategory = @category , tblcompany.intpremium = 0 my results not come out ordered 1, 2 , 0.. doing wrong here?? * solution * guys. below final sql using. select * tblcompanycategory inner join tblcompany on tblcompany.idcompany = ...

hopefully isn't redundant question--i'm not sure how word it. let's have list of items on asp.net page. list selectable in whenever user clicks on one, page postback , server code stores index or unique identifier of picture in viewstate property indicating selected. i minimize load on server , therefore store index or unique identifier representing image in way on client side. best way can think store said information in hidden field ), had 2 questions before go crazy: is security risk in way, shape or form (i.e., exposing implementation details of page)? is there better/best way more industry-standard? asp.net provide framework cleaner idea? seems common requirement me... i have been working in asp.net 2 years now. please, kind :-) best, patrick kozub the security risk if list items must remain non-selectable. sounds not case in situation. user knows information, because or selected item. note: if server ever information , pulls user, must valid...

i'm writing simple c program uses taglib library. had installed library in /usr/local , compiled , linked program against it. i've since removed library , attempting link against compiled version of library in location. problem when compile program now, compiles cleanly, when attempting run it, program looking library used exist in /usr/local/lib instead of new location. example, code , new taglib library in /users/mdi/code/tag. i'm compiling program this: cc main.c -wall -i./taglib/bindings/c -o tag -l./taglib/bindings/c/.libs -ltag_c like said, compile completes no errors or warnings. when attempting run binary, error: dyld: library not loaded: /usr/local/lib/libtag_c.0.dylib referenced from: /users/mdi/code/tag/./tag reason: image not found trace/bpt trap running 'otool -l' on binary shows this: tag: /usr/local/lib/libtag_c.0.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libsystem.b.dylib (compatibility version 1.0.0, current...

i looking use berkeley db create simple key-value storage system. keys sha-1 hashes, in 160-bit address space. have simple server working, easy enough written documentation berkeley db website. however, have questions how best set such system, performance , flexibility. hopefully, has had more experience berkeley db , can me. the simplest setup single process, single thread, handling single db; inserts , gets performed on 1 db, using transactions. alternative 1: single process, multiple threads, single db; inserts , gets performed on db, threads in process. does using multiple threads provide performance improvements? there 1 single db, , therefore it's on 1 disk, , therefore guessing won't boost. if berkeley db caches lot of stuff in memory, perhaps 1 thread able run , answer cache while has blocked waiting disk? using gnu pth, user level cooperative threading. not familiar details of pth, not sure if pth can have userlevel thread run while userlevel thread has bloc...

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

i have problem malloc(). weird. code in following. use random generator generate elements array. array opened malloc(). if array size smaller 8192, ok. if size larger 8192, shows segment fault. void random_generator(int num, int * array) { srand((unsigned)time(0)); int random_integer; for(int index=0; index< num; index++){ random_integer = (rand()%10000)+1; *(array+index) = random_integer; cout << index << endl; } } int main() { int array_size = 10000; int *input_array; input_array = (int*) malloc((array_size)); random_generator(8192, input_array); // if number larger 8192, segment fault free(input_array); } malloc() takes size in bytes, not number of elements. size of int typcially 4 bytes, allocating enough memory 2500 integers. allocating array_size bytes, while should allocating array_size * sizeof(int) bytes. so, error fixed input_array = (int*) malloc(array_size * sizeof(int)); p.s. never assume k...

so i've run confusion in past, , got around not using ninject. i'm redoing site i'm @ point ninject seems handy again, i've got myself confused. again . i have mvc3 project using repository pattern. currently, home controller creates few objects orderrepository.cs, customerrepository.cs , sends them service called orderservice.cs , customerservice.cs. have test project can use send in fakeorderrepository.cs , fakecustomerrepository.cs. handy unit testing go through project. however, realise declaring repositories in controller , unit tests, i'm setting dependency on objects. have no repositories passed, , have service layer use ninject "oh look, iorderrepository in constructor, better go orderrepository". the issue ran last time while can bind orderrepository instance or iorderrepository in contructor , bind 2 in global.ascx, seems leave unit tests high , dry. unless go in , switch every bind in global.ascx object want passed in (in case, fakeord...
