i have wpf project 1 window (mainwindow). depending upon config file shows 1 of 2 usercontrol's content. may horizontal (1920x1080) control or vertical (1080x1920) control. it's fine horizontal screen, when vertical loaded do: 1) rotate window/control 270 degrees 2) change primary screen orientation i prefer rotate application , don't interact windows api. can't change orientation manually, because have remote access computer. you can not rotate window object itself, positioned window management system built in windows. can, however, transform (and rotate) frameworkelement inside window. includes, not limited to, grid , button , textbox elements. all need edit layouttransform property on element want rotate, root element in window. set rotation 270/-90 degrees , wpf automatically rotate ui. because using layouttransform property, layout system scale ui correctly. rendertransform property causes control first rendered, rotated.

i have splash screen handles automatic login. if user logged in, sends s/he directly main activity, through following code: intent intent = new intent(activity, mainactivity.class); activity.startactivity(intent); activity.finish(); where activity activity finished (i'm not using this because method common automatic logins, manual logins, social logins etc.) however 70% of time, splash screen still there after finishing main activity. not occur during debugging. looks happens when login happens quickly, why never happens during debugging (because becomes slow). logging has helped see that, when problem happens finish() indeed being called, ondestroy() not. i have tried flag_activity_clear_top , doesn't help. nohistory work, brings unwanted finishing animation and, really, want know problem code is. i've used , don't see why fails. thanks in advance.

i got stuck texturing cubes - searched web , realized way give cube 6 different textures (with gldrawelements) create 24 indices. still faster gldrawarrays, seems quite illogically , horribly slow. understand purpose of gldrawelements deal complex models few indices share different texture coords. but, still pretty confused, because gldrawelements gave me perfomance boost (without effects, shader coloring) 50-67ms 10,000 cubes (gldrawarrays), 25-33ms 100,000 cubes. my question is: have accept it, or there still way come on this? i not know want archieve can try reduce number ob vertices in scene. make more faster. think if cube needs more 1 texture, can store them in texture atlas ans assign each vertex of cube corresponding texture coordinate image in texture atlas. reduce number of texture calls, there 1 texutre. in addition need render vertices/triangles visible user, not need texture of cube. i've found site explains lot of speeding rendering thousands of cube...

we have web app used ipads , iphones. using fastclick ( https://github.com/ftlabs/fastclick ) eliminate 300ms wait time mobile/tablet users. this makes snappier, interaction chart (using svg rendering) spotty. tapping works, not. ​users need able normal chart interactions tap point see value , toggle series on/off in legend. if disable fastclick, chart tapping works fine. fastclick has built-in way bypass element. add "needsclick" css class, , leaves element alone. put css class on div chart rendered in, each clickable element in chart apparently needs have "needsclick" class added it. is possible? i gave up. added "needsclick" svg elements after chart rendered, , ipad clicking still weird. worked, not consistently. i think these libraries both trying solve same problem , stepping on each other it, removed fastclick. this fastclick 1.0.6 , kendo ui v2015.1.408.

tl;dr: can explain difference in implementing client-side google login flow between these 2 platforms? the backstory: i've been trying implement client-side google sign in website. first, implemented google+ platform global settings using tags, user session monitored. got info here: https://developers.google.com/+/web/signin/ however, encountered problem site automatically check user login state if user not logged in, resulted in many 'toastr' messages of 'logged out', implemented in signincallback function. pretty annoyting. so did research , stumbled across 'quick start app' , browsed through it. way more complicated guide, many elements documented on google identity platform, here: https://developers.google.com/identity/sign-in/web/reference now don't understand correct way of implementing login - lightweight google+ button tag callback check user state, or robust gip way listeners, gapi instances , all? different these platforms offe...

using angularjs, have double loop display data, , filter year. when, given year, have no results, want display message "no results...", because of double loop, i'm not able work here demo http://plnkr.co/edit/oswsyxk8bnvmj1rfwhj0?p=preview the div want display when <div ng-if="personnes.length < 1" class="noresults">no results</div> to see example no results, choose "2013-2014" in year dropdown thanks lot well, not pretty like, anyways. update html follows: <div ng-if="filterarray(resultspersonnes).length < 1 && $first" class="noresults">no results</div> and in controller create new function: $scope.filterarray = function(resultspersonnes) { return resultspersonnes.filter(function(prop) { return prop.fraiss[0].annee == $scope.annee.id; }); } so repeats angular in ng-repeat filters. see updated demo .

in code, method being called repeatedly within loop so: foreach (var file in files) { somemethod(file); } the method throw exceptions, don't want code exit loop after first exception. furthermore, code above being called web api controller, need way pass exception information controller, handled (log exception , return error response client). what i've done far catch , store exception in list. var errors = new list<exception>(); foreach (var file in files) { try { somemethod(file); } catch(exception ex) { errors.add(ex); } } considering rethrowing errors in list not option, best approach return exception information controller? use aggregateexception . you can pass list<exception> constructor , throw that. at end of loop do: aggregateexception aggregateex = new aggregateexception(errors); throw aggregateex; (or return aggregateexception )

i have binary outcome variable (disease) , continuous independent variable (age). there's cluster variable clustvar. logistic regression assumes log odds linear respect continuous variable. visualize this, can categorize age (for example, 0 <5, 5 <15, 15 <30, 30 <50 , 50+) , plot log odds against category number using: logistic disease i.agecat, vce(cluster clustvar) margins agecat, predict(xb) marginsplot however, since categories not equal width, better plot log odds against mid-point of categories. there way can manually define values plotted on x-axis marginsplot should 2.5, 10, 22.5, 40 , (slightly arbitrarily) 60, , have points spaced appropriately? if interested, achieved required graph follows: recategorised age variable differently using (integer) labels represent mid-point of category: gen agecat = . replace agecat = 3 if age<6 replace agecat = 11 if age>=6 & age<16 replace agecat = 23 if age>=16 & age<30 replac...

using node/express - want json out of request headers, want safely. if reason it's not valid json, it's fine, can return false or whatever , reject request , keep going. problem throws syntax error if it's not valid json. want syntax error blow up, not in case. var boom = json.parse(req.headers.myheader); do scrape stack , check bad parse call particular module, , if it's case, ignores it? seems bit crazy. surely there's better way. edit: aware try/catch blocks a way of handling error, best way in node app? way block node? the best way catch invalid json parsing errors put calls json.parse() try/catch block. you not have other option - built-in implementation throws exception on invalid json data , way prevent exception halting application catch it. using 3rd party library not avoid - must try/catch on json.parse() call somewhere. the alternative implement own json parsing algorithm more forgiving on invalid data structures, feels...
