i'm having trouble coming xaml page bind keyboard layout displayed on page. have observablecollection of rows contain keyboardkey datatypes specify width of button. collection bound listbox in xaml. problem i'm having on keyboards the height of key spans 2 rows, xaml listbox not support. avoid hard coding bunch of keys in xaml. thoughts on how approach this? you can create own layout buy inheriting 1 of container controls , overriding arrangeoverride method. you can find example here: http://www.wpftutorial.net/customlayoutpanel.html when creating virtual keyboard, declined automatic layout , put buttons manually in designer. think in cultures better put key rows horizontal shift , in others better to place buttons under each other. have flexible layout , can edit in designer.

i'm implementing iobserver. are there conventions throwing exceptions iobserver? can onnext or other method of implementation throw exceptions? what should happen if exception thrown in onnext or oncompleted - should catch exceptions , call this.onerror(ex)? what happen if onerror throws? from previous discussions in rx forums, best practice if onnext throws, let bubble handled subscribe method, if user decides handle it, so. actually answer not simple, can check out thread related question, here : more closely related thread: what if exception thrown observer in onnext

im making online game, , in many online games need loads of data being transfered via internet, need able compress data efficiently. for instance want send client server character coordinates. edit: yeah bad example, let me change values... x coordinate(say -32 32).(65 diferent possible values) y coordinate(-32 32).(65 diferent possible values) z coordinate(-16 16).(33 diferent possible values) i know x stored before y stored before z on byte array before sending. i know in server x cannot lower -31 nor higher 32, same other values. 65*65*33 = 139.425 diferent possible combinations of values 3 numbers = 17 bits. 7 + 7 + 5 = 19 bits. so if store x in first 7 bits, y in next 7 bits , z in next 5 bits take 19 bits , able read them in other side ease, since posible combinations of values 3 numbers can take take 17 bits store feel im losing space here. there way compress 3 numbers using less 19 bits? of course 19 bits , 17 bits both need 3 bytes, if 17 bits , 15 bits m...

i'm trying find maximum diagonal product of 2 digit numbers in 20x20 matrix. this gives error message : i <- 17:1 z <- (j in 1:(18-i)) {b <- max ((x[i,j]*x[i+1,j+1]*x[i+2,j+2]*x[i+3,j+3]))}} but doesn't: z <- (i <- 17:1) {for (j in 1:(18-i)) {b <- max ((x[i,j]*x[i+1,j+1]*x[i+2,j+2]*x[i+3,j+3]))}} but second version gives me number small . why first 1 not work, think yield correct answer, don't understand error message. this looks wrong. you cannot assign result of for loop variable. , max() on scalar variable nonsense. lastly, matrix x isn't specified. i'd retry smaller, , maybe print interim results screen. walk before run still advice. later can still vectorise sprint solution.

i've got uibutton in uiview, in uiviewcontroller i've allocated , inited .xib file. when hooking ibaction 'touch down' event of uibutton triggers correctly. if hook 'touch inside' event doesn't respond. other events don't work either. 'touch drag enter', 'touch drag exit', 'touch outside' etc. touch down. does have idea why might be? rich first, can absolutely, positively guarantee uibuttons correctly connected in ib responds expected touch-up-inside events. (can imagine if didn't?!) given that, it's fair bet have not hooked things expect. here things try: make action print log statement first thing: nslog(@"%s", __pretty_function__); check in ib function button wired touch-up-inside action. (later, can wire multiple events but, testing, want simplify as possible.) make sure button 50x50 or bigger. (small buttons hard press.) for now, make button rounded-rect button. if had im...

our software needs able register ocx @ runtime. ocx lives in program files directory of app. find if manually fire cmd line admin , run command works great, if fire our app admin , let app try register ocx, fails. notice app able run regsvr32 when run build directory, presumably because own build dir. still have run admin though. have ideas going wrong? thanks, brian the answer firstly, i'm sloppy, , secondly command line args passed regsvr32 need wrapped in double quotes. never occurred me because wrote code so: string args = "/s " + path.combine(mp_xxxx_dir.fullname, map_point_ocx) ; when should have looked like: string args = "/s " + "\"" + path.combine(mp_xxxx_dir.fullname, map_point_ocx) + "\""; hope helps else :)

how can build novice-usable (clickable download) installer mac os x command-line tool, , should binary installed novice user no knowledge of shell paths can open terminal app , type "foo" run freshly installed foo tool? can installer install documentation user can type "man foo"? are there other options should considered make use of pure command-line (stdin, stdout) tool accessible novice mac user? what's minimum version of os x you're targeting? 10.6 (and iirc 10.5) include /usr/local/bin in default path, 10.4 did not. long don't need support 10.4, should put executable in /usr/local/bin , man page in /usr/local/share/man/man1 (or whatever appropriate chapter number is). for building installer itself, can use apple's packagemaker utility (part of xcode). create prototype local folder bin , share/man/man1 subfolders , populate them files. create package project in packagemaker, , choose organization name , minimum target os. d...

i have simple r beginner's question: how express sum below concisely in r ? sum_{i=1}^n / (a+i) i tried following, there must better way, without calling for : r<-0 for(i in 1:n){ r <- r + (a / (a+i)) } thanks! i believe it's simple as: sum(a/(a+1:n))

i have been working on website using mvc preview 1 since came out. beta out, have updated system beta. there not alot of out there upgrading preview 1 beta, , rebuilding caused lot of problems. have done far: 1) copied web.config new mvc3 beta project (to correct sections , values). 2) added references system.web.helpers , system.web.webpages, references match newly created project. 3) changed @import @model per new format. the problem getting, views in existing project, being derived off of system.web.web.pages , in new project being derived off system.web.mvc.webviewpage<>. what missing causing base class issue. you need copy /views/web.config new mvc 3 project - base page class defined

i have implemented pid function using formula, correction = kp * error + kd * (error - preverror) + ki * (sum of errors) what should keep output between range? 0-255 if disregard value not between 0 255 produces jiggly behavior? correction = ... correction2 = correction; if(correction < least) {correction2 = least;} if(correction > most) {correction2 = most;} then use correction , correction2 output appropriate. don't correct based on correction2 , wonder why behaves in odd way when reach edge of least <-> most.

how find number float or integer ? 1.25 --> float 1 --> integer 0 --> integer 0.25 --> float check remainder when dividing 1: function isint(n) { return n % 1 === 0; } if don't know argument number need 2 tests: function isint(n){ return number(n) === n && n % 1 === 0; } function isfloat(n){ return number(n) === n && n % 1 !== 0; }

i trying create custom component using java awt or swing rectangle number of components inside of it, including other rectangles. this: ╔══════╗ ║ ┌┐ ║ ║ ├┘ ║ ║ ║ ╚══════╝ and needs component can preferably draw 1 instruction. myframe.add(new mycomponent()) . what best way this? there way can using rectangle , or should go jpanel or swing? i recomend extending jpanel , overriding it's paintcomponent() method. see another answer of mine on that. basically, when rectangle 'drawn' on panel, want save member of jpanel . then, in paintcomponent method, draw of rectangles have saved in jpanel . this how implement 'draw' method: list<rectangle> recs; list<stroke> strokes; list<color> colors; public void drawrectangle(rectangle newr, stroke stroke, color c){ recs.add(newr); strokes.add(stroke); colors.add(c); } and, paint component similar to: protected void paintcomponent(graphics g){ super.pain...

i seemingly straightforward question can't seem find answer (and hindering app). i have background thread running paricular method: -(void)processimage:(uiimage *)image { nsautoreleasepool * pool = [[nsautoreleasepool alloc] init]; //process image here in background here [pool drain]; } this works great, question comes when want call method inside already-background method. call stay in background? need add nsautoreleasepool * pool = [[nsautoreleasepool alloc] init]; , [pool drain]; new method make run in background well? any advice helpful. bit confused this. many thanks, brett it stay in background, on same thread called from. some threading notes consider this: it may not obvious, if call timer background thread, , thread exits before timer supposed go off, timer not called. recommended setup timers main thread you dont need autorelease pool unless spawn thread. any ui updates should done on main thread

ok, i'll admit don't entirely "get" lambda expressions , linq expression trees yet; lot of i'm doing cutting , pasting , seeing works. i've looked on lots of documentation, still haven't found "aha" moment yet. with being said... i'm attempting dynamically add groupby expression linq expression. followed question here: need creating linq.expression enumerable.groupby and tried implement saw there. first off, i've got entity classes database, , table calledobjcurlocviewnormalized i've got method initial call, public iqueryable<objcurlocviewnormalized> getlocations() { iqueryable<objcurlocviewnormalized> res = (from loc in tms.objcurlocviewnormalized select loc); return res; } so can call: iqueryable<metamericanlinqdatamodel.objcurlocviewnormalized> locations = american.getlocations(); no problem far. now, want group arbitrary column, call this: var group...
