i've been trying 2d distance joint working in unity. want free rotation both body joint , connected body, need mass , other constraints adhered to, such fixing rigidbody's position. i've tryed days now, no luck configuring joint type. tryed verlet constraint using: float xdistance = hinge.transform.position.x - target.transform.position.x; float ydistance = hinge.transform.position.y - target.transform.position.y; float newdistance = mathf.sqrt( xdistance * xdistance + ydistance * ydistance ); float con = ( newdistance - maxdistance) / newdistance; vector3 movetarget = new vector3( xdistance * 0.5f * con , ydistance * 0.5f * con, 0.0f ); hinge.rigidbody.moveposition( hinge.transform.position - movetarget ); target.rigidbody.moveposition( target.transform.position + movetarget ); but doesn't take account mass/force or fixtures. can see here want movement on x/y , rotation on z. help? i know isn't answer, add comment button not there. i'm unit...

can explain me difference between vector , linked list adt in c programming language context. thanks. well, in c, there no "vector" , "list" data types available directly in c++ std library. in terms of "abstract data type", vector considered represent contiguous storage, , linked list considered represented individual cells linked together. vectors provide fast constant time random-access read , write operations, inserting , deleting vector elements take linear time. lists have linear lookup performance find element read , write, given element location, have constant time insertion , deletion. can add items start , end of list in constant time (if adt implementation caches location of last element in list).

i bit confused. implemented own usercontrol , want control discover components (like binding source) hosted in same control @ design time. code this: private void findcomponentbyname(string aname) { foreach(component component in this.container.components) { if (component.tostring()==aname) { dosomething(); break; } } } this code not working either @ design time or run time container null. if run code in form not in usercontrol private component findcomponentbyname(string aname) { component result = null; foreach (component component in this.components.components) { if (component.tostring() == aname) { result = component; break; } } return result; } it works, components not null , man...

i trying make fluid layout app , having trouble using css height percentages. using horizontal size of window specify height % when want getting percentage vertical size of window. possible or out of luck? width: x%; height: y%; x , y being percentage want element be. both being determined horizontal size of window, , want each use it's respective axis. if use javascript update absolute height of parent node, height % begins mean something. playing around, p or div first generation child of body ignores css height%; wrap in absolute height. if don't know height before hand, use onload js function set it.

i have columns may contain data if user wants provide it. example | email | first name | last name | email - required column set not null - default: none first name - not required column set null - default: null last name - not required column set null - default: null in phpmyadmin when creating/editing column; has option saying default: drop down showing none | defined | null | current timestamp because first name | last name optional , not required should choose default null or maybe none? which best , why please? i know there many discussions on not find answered question; more in regards allowing null or not null, question default value. you should set them default:null if user doesn't provide info fields, should null obviously.

similar feature as: function __autoload(undefinedclass) { include 'library/'.undefinedclass.'.php'; } ?> python package = _init.py, bios=mbr, c++= stil or templates, php5 = autoload, python 3.x ? no, there no such feature, because don't need it. if want not import module until it's needed, import when it's needed. if want avoid circular imports, pretty same thing. there, question has answer. :-)

i looking sending data server in compressed format client(with ajax requests), , decompress data browser? there library this? i not looking compressing javascript files! thanks... edit: think question not clear enough, don't want compress html files, want store compressed lzma files or other compression format on server(like obj file), , need decompress them after got ajax. not simultaneous compression/decompression gzip. opening zipeed files after getting them javascript. your web-server (and browser) should capable of handling transparently using gzip. how setup depend on server using. checkout mod_deflate in apache or enabling gzip in nginx. the browser automatically decompress data before reaches xhr handler , can safe in knowledge data compressed as possible in transit.

i've got forms use absolute positioning , pixels win7 adds "handles" enhance translucency screwing controls up. i'd take them back. tried using code in 1 of answers here: can make borderless application main window in windows, without ws_popup style? specifically answer goleztrol provided utilizing override in showform call setwindowrgn. code's behavior bit different under w7 xp, , in case can't effect i'm looking for. for standard tform in xp, quantity width-clientwidth = 8, , in win7, it's 16. i'd 8 pixels back. i'd height pixels while i'm @ it, though width more important. i think bad practice rely on border width of form, especially since end-user can change in control panel! clientwidth property there use instead of width . set former whatever like, , latter computed.

situation: i have webpage opens modal windows (light boxes) contain forms user can input data. users navigate using keyboard, tabbing 1 field next. problem: when modal window opens, window active, rest of page not accessible using mouse, elements can reached tabbing out of modal window. question: how can restrict movement using tab button elements within form window? the thing can think of using javascript set tabindex=-1 on form elements (and other focusable elements) when modal window opened , set tabindex values previous values when modal window closed. there simpler/better way? no, it's way. find elements have tabindex greater -1 † , don't belong modal. create array &ddagger; , fill references each element along original tabindex . set each element's tabindex -1 can no longer receive focus keyboard. when modal dialog closed, iterate on array , restore original tabindex . here's quick demo: function isdescendant(anc...

the problem i'm trying solve follows: i'm given sorted list must pair first , last items in list. must pair 2nd , (last-1) items in list until list either empty or 1 element remains. must return list of pairs. the steps decided take problem first check if list's length greater 1. if wasn't, means have list of 0 or 1 elements. then first , last items in given list, delete them list, pair them, , recursively call same predicate on new list. once i've gone way down 0/1 items, pop , append them return list. the problem i'm having when try append pair l = [first,last] return list, errors out. code listed below. t input list. first/2 gets first item in list. pair/3 strips away info p1 , p2 , creates l = [p1,p2] . getmatches(t,k,returnlist) :- ( length(t,val), val > 1, first(t,p1), last(t, p2), delete(t,p1,g), delete(g,p2,h), pair(p1,p2,l), getmatches(h,k,returnlist), append(l,k,returnlist...

i need similar in php: struct msg_head { unsigned char c; unsigned char size; unsigned char headcode; }; struct get_info { struct msg_head h; unsigned char type; unsigned short port; char name[50]; unsigned short code; }; void example(get_info * msg) { printf(msg->name); printf(msg->code); } i created general purpose php struct class, emulate c-structs, might useful you. code , examples here: http://bran.name/dump/php-struct example usage: // define 'coordinates' struct 3 properties $coords = struct::factory('degree', 'minute', 'pole'); // create 2 latitude/longitude numbers $lat = $coords->create(35, 40, 'n'); $lng = $coords->create(139, 45, 'e'); // use different values name echo $lat->degree . '° ' . $lat->minute . "' " . $lat->pole;

the question is: possible create sparse matrix using following sparse list implementation? in special, using class template class template (sparselist*>)? i've created class template named sparselist can add elements in whatever index want. i'd use create sparsematrix class template. tried following... //sparsematrix.h template <typename t> class sparsematrix { public: sparsematrix(); private: sparselist<sparselist<t>*> *matrix; }; template <typename t> sparsematrix<t>::sparsematrix() { matrix = new sparselist<sparselist<t>*>(); } but when try instantiate on main... int main() { sparsematrix<int> *matrix; matrix = new sparsematrix<int>(); //without line compiled normally. return 0; } i got following error... in file included src/main.cpp: sparsematrix.h: instantiated 'sparsematrix<t>::sparsematrix() [with t = int]' main.cpp: instantiated here...

i creating text editor. text-box control subclass of textbox called editor . main form, mainform , has instance of editor . when mainform wants to, say, load text document, calls editor.loaddocument(string path) . editor.loaddocument calls document.load(string path) . the same kind of thing happens save: mainform --> editor.savedocument --> document.save . it seems editor acting middleman unnecessarily here, i'm thinking of letting mainform access document directly: editor.document.load(path) . editor still create , maintain document ; provide direct access it. note create bidirectional association: editor have document , document have editor ( document uses editor.text , subscribes editor.textchanged ). i have 2 questions: is design? do bidirectional associations create slowdown pertaining garbage collection when app exits? you need read patterns such model-view-controller. generally, ui should activate operations directly on...

is possible run asp.net , asp classic in separate app pools? asp classic pages mixed within same asp.net application , sub folders. basically, have site , run asp.net portion in own app pool , asp classic in separate app pool. intent run asp.net in "web garden" configuration; can not if asp.net , asp classic in same app pool, due fact classic portions rely on session variables in process. we have considered rewriting classic self contained in 1 directory, , switching sql-based session storage classic. determined easier attempt split app pools, these 2 options require significant time investment. thank assistance! that's not possible afaik, can configure iis application pool application.
