this may long shot i'm out of ideas. i've got vs c# solution 3 projects in it. there's class library project , 2 application projects depend on class library. class library in turn depends on few other dlls including avalonedit dll sharpdevelop project. one of applications building , running fine, including use of own control wraps avalonedit control. other application failing run , seems failing @ point when avalonedit control initialised via xaml in wrapping control. the problem don't see errors in debug output @ all, see dll loaded message , nothing. if step constructor of control step never completes. debugger says app running, apparently spinning somewhere in avalonedit dll when underlying edit control constructed xaml side. i have assume there's issue difference in environment between 2 projects i'm kind of stumped how proceed in tracking problem down. going have somehow arrange matters can put break in avalonedit source? edit: if pause/break

i thinking on data types ranges, question arises. know signed char's range -128 127. got how 127 comes, i.e. 0111111 = +127 but not how -128 comes? if on sign bit 11111111, how equal -128 ? most of time, computers use what's called 2's complement represent signed integers. the way 2's complement works possible values in huge loop, 0, max_value, min_value, zero, , on. so minimum value maximum value +1 - 01111111 = 127 , , 10000000 = -128 . this has nice property of behaving same unsigned arithmetic - if want -2 + 1 , have 11111110 + 00000001 = 11111111 = -1 , using same hardware unsigned addition. the reason there's value on low end choose have numbers high-bit set negative, means 0 takes value away positive side.

i want make synchronous request server. want entire program stop processing until request complete , server has responded; proper way of doing this? you don't want entire program stop processing until server responds, because runs risk swf trigger "script has executed 15 seconds" modal dialog warning appear in front of user, @ point might consider action lost cause. considered "crash" , "not idea." what you're trying accomplish believe halting execution (including rendering) achieve? if really want make application non-responsive user activity during request, might able away setting mousechildren = mouseenabled = false on application's root movieclip. if need stop timeline animations, you'll have come way globally find / stop them yourself. obviously, enter_frame events you're listening for, or timers you're running should stop when make request. you might able away setting swf's framerate 0fps in code (

possible duplicate: calculating angle between 2 lines without having calculate slope? (java) i need find angle between 3 points. have point , point c being 2 points of ray , have point b being central point points , c extend from. if create line between points b , a, , create line between points b , c, can find angle between 2 lines. take line direction vector a(a,a',a") , line b direction vector b(b,b',b"). a.b = ||a||.||b||.cos(t) a.b cos(t) = -------------- ||a||.||b|| take a(1,2,3) ; b(4,5,6) ; c(3,2,0) calculate angle between lines ab , ac. line ab has direction numbers (3,3,3) , line ac has direction numbers (2,0,-3). hence 6 + 0 - 9 cos(t) = ----------------- sqrt(27) .sqrt(13) update: use arccos(cos(t)) obtain angle. convert radians degrees multiply 180/π convert degrees radians multiply π/180

i trying render opengl es surface ndk, got halted in work. have setup similar 3d example in ndk. have class inheriting glsurface view , 1 inheriting glsurfaceview.renderer. in .c file, have simple method nothing. void function nothing in it. can call function in class inherit activity oncreate method. private static native void nativesetup(); @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); requestwindowfeature(window.feature_no_title); mglview = new graphglsurfaceview(this); setcontentview(mglview); nativesetup(); } the program works fine. however, if put call (and declaration) in 1 of glsurfaceview classes, program fails (nativesetup call in question). have verified working fine without native call (a colored surface drawn). have ideas why cannot call native code glsurface classes? my c file: #include <string.h> #include <jni.h> void java_com_test_intro_nativesetup( jnienv* env ){} my jav

edit, slight problem caused fix in respond below: now these rules clash: $router->addroute('view-category', new zend_controller_router_route(':id/category/:page', array('module' => 'default', 'controller' => 'category', 'action' => 'view', 'page' => null))); $router->addroute('management/category', new zend_controller_router_route('management/category/', array('module' => 'management', 'controller' => 'category', 'action' => 'index'))); so /management/category/reset gets captured view-category rule, if switch there order. never used issue. ideally if caught /management or /administration ignore :name/category rule. possible make /management , /administration ignore previous rules , route controller action there no specific rules otherwise in areas. old question: $router->addroute('v

i want simple cron-like management in php project there things have: php job worker plain script placed in subdir inside project directory there subtree /cron/daily, /cron/monthly ... etc in project root contains workers there no need mess crontab every worker added. all scripts run run-parts corresponding frequency, , respective output logged separate files /var/log/projectname/cron/daily/somescript.log would great have /cron/daemon dir containing scripts should run forever (minutely) no more 1 instance i've had experience kind of scheduling system in 1 project , loved it. provides number of neat things: jobs project scripts , reside in project dir, tracked git. no need crontab messing. logs sorted out. daemons easy build. i use /bin/run-parts on project /cron subdirs, didn't manage split logs wanted. , splitted logging nice feature have. so, thought kind of systems created many times before, there ready use solution php project? it's more smart ru

i have threadsafe object expensive create , needs available through application (a lucene.net indexreader). the object can become invalid, @ point need recreate (indexreader.iscurrent false, need new instance using indexreader.reopen). i'd able use ioc container (structuremap) manage creation of object, can't work out if scenario possible. feels kind of "conditional singleton" lifecycle. does structuremap provide such feature? alternative suggestions? i use scope of perrequest , not return indexreader directly. instead, i'd return abstraction of indexreader perform check on static reference held on class level. then, when property on shim/proxy/abstraction accessed, check static reference (you make thread-safe, of course) , re-get indexreader if needed before delivering user.

i've been told make class abstract: public abstract class airplane_abstract and make method called move virtual public virtual void move() { //use property ensure there valid position object double radians = planeposition.direction * (math.pi / 180.0); // change x location x vector of speed planeposition.x_coordinate += (int)(planeposition.speed * math.cos(radians)); // change y location y vector of speed planeposition.y_coordinate += (int)(planeposition.speed * math.sin(radians)); } and 4 other methods should "pure virtual methods." exactly? they right now: public virtual void turnright() { // turn right relative airplane if (planeposition.direction >= 0 && planeposition.direction < position.max_compass_direction) planeposition.direction += 1; else planeposition.direction = position.min_compass_direction; //due north }

in question here @ stack overflow, came across helpful code snippet send code google closure compiler, can minify javascript files pretty good. the problem i'm facing returns no compiled code in cases don't expect so. code: this works, i.e. returns minified code: dim script = "function test(name) {alert(name);}test('new user');" this one, on other hand, not return anything. statistics sent, no compiled data...: dim script = "function test(name) {alert(name);}" rest of code work: dim data = string.format(closurewebservicepostdata, httputility.urlencode(script)) _result = new stringbuilder _httpwebrequest = directcast(webrequest.create(closurewebserviceurl), httpwebrequest) _httpwebrequest.method = "post" _httpwebrequest.contenttype = "application/x-www-form-urlencoded" '//set content length length of data. might need change if you're using characters take more 256 bytes

i have c# based ui uses c++ based dll. requirement pass big chunk of memory c# dll. dll write memory buffer , pass c#. have used intptr & global memory functions this. works fine. the question is, how verify if marshal.freehglobal() has cleaned memory? using big chunk of memory, in terms of mbs. want make sure memory cleaned instantly. if pass valid handle marshal.freehglobal , will freed. since method doesn't return value, can't sure whether cleaned up. if have doubt whether you're passing right thing freehglobal , suggest code isn't clean should be. if want make sure, call localfree windows api function, passing handle have passed freehglobal : [dllimport("kernel32", setlasterror=true)] static extern intptr localfree(intptr mem); // now, free block of memory allocated marshal.allochglobal intptr rslt = localfree(memptr); if (rslt == intptr.zero) { // success! } else { int err = marshal.getlastwin32error(); // error. }

i have code need fix print "hello world!". reason prints letters scrambled. sub main() dim s string = "hello world!" parallel.for(0, s.length, sub(i) console.write(s(i)) end sub) console.read() end sub any suggestions? sub main() console.write("hello world!") end sub if must print 1 character @ time, write: sub main() dim s string = "hello world!" dim integer i=0 s.length-1 console.write(s(i)) end end sub
