can recommend p4win-like alternative perforce, supports shelving , may open source? needn't cross platform, windows fine. i'm asking i'm not fan of new p4v interface, , found p4win lot more intuitive, easier use, , more stream lined. i haven't found in google searching, i'm hoping nexus of programmers might know of hidden jewel out there. :) this isn't answer, don't have enough rep comment on original post. if primary concern support shelving, can still use shelve/unshelve through command line. hook p4win ui using simple python (or language of choice) script that's set external tool runs on changelists.

i have html select list (let's call list a) dynamically populated list of values. need change select list (list b) depending on value of list a. part, can do. ordinarily, user selects one element of list a, , gets list b contingent on list a. however, first element of list "all values." therefore, in instance, want list b consists of aggregate of of values possible list b. because available values of list dynamically generated, can't pull list b values. need pull list b values contingent on list values shown . to this, want iterate through of values in list a, , append list b each item in list a. i'm stuck. how can populate array consist of of values in select list? again, because list populated dynamically, way list of these values pull them select list element. i tried this: iterate_models = $.map($('#lista'), function(e) { return $(e).val(); }); this did not give me array of values of each element in #lista. can't figure ...

this total newbie question, can't figure out figured ask here , see happened. here's problem: java programming class, supposed download .class file created our instructors containing custom-made class methods supposed use in assignment. know of code create class within actual program, can't figure out directory place .class file in. have tried src , bin folders inside project directory, , placed directly project directory, nothing seems work. instructors put in same directory java program, using jgrasp. doing wrong? you can place class file anywhere, sure add directory project's build path. right click on project, properties @ bottom build path, til find add class folder.

i working on wpf project c# (.net 4.0) capture sequence of 300 video frames high-speed camera need saved disk (bmp format). video frames need captured in near-exact time intervals, can't save frames disk they're being captured -- disk i/o unpredictable , throws off time intervals between frames. capture card has 60 frame buffers available. i'm not sure best approach implementing solution problem. initial thoughts create "buffertodisk" thread saves images frame buffers become available. in scenario, main thread captures frame buffer , signals thread indicate ok save frame. problem frames being captured quicker thread can save files, there needs kind of synchronization deal this. thinking semaphore tool job. have never used semaphore in way, though, i'm not sure how proceed. is reasonable approach problem? if so, can post code me started? any appreciated. edit: after looking on linked "threading in c# - part 2" book excerpt, decided impleme...

how can best write query selects 10 rows randomly total of 600k? a great post handling several cases, simple, gaps, non-uniform gaps. http://jan.kneschke.de/projects/mysql/order-by-rand/ for general case, here how it: select name random r1 join (select ceil(rand() * (select max(id) random)) id) r2 r1.id >= r2.id order r1.id asc limit 1 this supposes distribution of ids equal, , there can gaps in id list. see article more advanced examples

as title says, have black font white border in textbox . how achieved? cheers. check out blacklight controls @ http://blacklight.codeplex.com/ . in particular @ sample on http://mightymeaty.members.winisp.net/blacklight.silverlight/ | visual controls | text | stroke text block (alpha).

here's want - given couple of [image] layers inside scrollviewer, i'd apply same scaling factor layers. in xaml, have scroll viewer hosts grid hosts 2 image controls. have checkbox controls visibility of top image. right now, have scaletransform each image, , apply same scale both. is there way unify scaling in 1 container? sure can apply scale transform @ higher level, e.g. apply grid. <grid.layouttransform> <transformgroup> <scaletransform scalex="1.0" scaley="1.0"/> </transformgroup> </grid.layouttransform> that automatically propagate transform down child ends inside grid. regards, donovan

i want write string of assembly code in c# , have sent win32 api compile , execute , results back. example: string str = "mov 1,2;xor ebp,ebp"... sounds hard suggestion helpful. i doubt there's win api compile & execute assembly. best write file, execute masm (or whatever it's called these days), link execute resulting program. can't imagine trying pretty last way try solve problem! if want compare native & managed code, write 2 programs more or less same thing. there no reason generate assembly .net. can use suitable tool this. masm, debug etc.

i noticed strange behaviour when binding array listbox. when add items same "name", can't select them in runtime - listbox goes crazy. if give them unique "names", works fine. please explain why happening? the view: <window x:class="listboxtest.listboxtestview" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:listboxtest" title="listboxtestview" height="300" width="300"> <window.resources> <local:listboxtestviewmodel x:key="model" /> </window.resources> <grid datacontext="{staticresource resourcekey=model}"> <listbox itemssource="{binding items}" margin="0,0,0,70" /> <button command="{binding path=add}" content="add" margi...

i'm new programming, sorry if question seems trivial. have looked answer, can't straight one. we've covered in class, brain failing me right . in c, need make array each element corresponds word. edit: remembered should pointer array. i'm doing... main() { char *line[maxline]; // points beginning of words in compare[] char compare[maxline]; // words read in int counter[maxline]; // counter words appear more once char c; int = 0; int n; (n=0; c!=eof; n++){ while ((c=getchar())!=' '||c!='\n'||c!=eof){ compare[i]=c; i++; } line[n]=compare; = 0; } i'm aware that's not whole thing because need make compare have new address, how 1 suggest going doing that? need use structs or there way? should using malloc that? i apologize if asked stupid question. since first post here, input on way went asking question appreciated since respect community incred...

hey guys, trying socket programming in php. so running socket "server": $address = '127.0.0.1'; $port = '9999'; $mastersocket = socket_create(af_inet, sock_stream, sol_tcp); socket_set_option($mastersocket, sol_socket, so_reuseaddr, 1); socket_bind($mastersocket, $address, $port); socket_listen($mastersocket, 5); $clientsocket = socket_accept($mastersocket); so open ssh , run script. running, no errors. then have php script attempts connect this: $fp = fsockopen("me.com", 9999, $errno, $errstr, 30); fclose($fp); but it's giving me: warning: fsockopen(): unable connect me.com:9999 (connection refused) how begin fix this? you haven't finished listening socket sequence, need call socket_accept accept new connections. there example in comments in php documentation. $clients = array(); $socket = socket_create(af_inet,sock_stream,sol_tcp); socket_bind($socket,'127.0.0.1',$port); socket_listen($socket); soc...

how can generate different random numbers @ runtime? i've tried srand((unsigned) time(0)); but seems me random number on every startup of program, not on every execution of function itself... i'm trying automate tests random numbers, random iterations, number of elements, etc... thought call srand((unsigned) time(0)); at beginning of test function , bingo, apparently not. what suggest me do? srand() as others have mentioned. srand() seeds random number generator. means sets start point sequence of random numbers. therefore in real application want call once (usually first thing in main (just after setting locale)). int main() { srand(time(0)); // stuff } now when need random number call rand(). unit tests moving unit testing. in situation don;t want random numbers. non deterministic unit tests waste of time. if 1 fails how re-produce result can fix it? you can still use rand() in unit tests. should initialize (with srand()) unit t...
