when place 2 elements (buttons, etc.) side-by-side in flow panel in google apps script gui builder, rearranged in column. in other words, flow panel behaving vertical panel, not flow panel. on related note, list of widgets in gui builder includes vertical panel, not horizontal panel. consequently, can't place items side-by-side short of using absolute placement (which imagine not adjust different window sizes). is bug? being fixed? there workaround? (for reference, i'm working through example in chapter 3 of james ferreira's "google script" book.) the first thing check width of elements. admit never use gui builder. not doesn't work, it's not how write code.

i made new wpf project web browser control in it. when load html page css3 transformations in both simple app , plain ie10 (both on windows 8, versions), there vast different in performance. inside webbrowser control choppy, in ie10 smooth. things have tried: installed high end video card added dword value of 10001 wpfapplication1.exe registry @ hklm\software\microsoft\internet explorer\main\featurecontrol\feature_browser_emulation . (we set value wow6432 version of same key) set feature_gpu_rendering 1 wpfapplication1.exe (e.g. hkey_local_machine\software\wow6432node\microsoft\internet explorer\main\featurecontrol\feature_gpu_rendering ) confirmed both these new values being read application using process monitor. does know more tricks force web browser control behave ie10? know there lot of featurecontrols turned on default in ie off in web browser control, doesn't more affect animation performance.

i'm building simple phonegap application new messages mysql server , show them user. application supposed json { "key": [ { "message": "test" } ] } from server every minute , alerts if there new. right alerts message "test" every time though json has changed this: {"key":[]} after application has asked server first time. this js use setinterval ( "getmessages()", 60000 ); function getmessages() { $.getjson(serviceurl + 'messages.php' ,function(result){ $.each(result.key, function(index, field){ alert(field.message); }); }); } the request being cached browser. change url to: serviceurl + 'messages.php?' + new date().gettime() this trick browser thinking it's different request each time , therefore avoids issues caching.

i've started working yii, forgive ignorance :) i have sql query returns multiple rows (array of arrays), want insert rows db: $queryresults = $command->queryall(); $model=new campaigns(); foreach ($queryresults $cactive) { $model->setisnewrecord(true); $model->attributes=$cactive; if($model->save($cactive)) { echo "good!"; } the problem though i'm setting model new record has record of previous pk (since it's same model). do need create new model each row? (doesnt seem likely...) thanks always, danny you have create new instance @ every insert, this, otherwise updating 1 model on , over. $queryresults = $command->queryall(); foreach ($queryresults $cactive) { $model=new campaigns; $model->attributes=$cactive; if($model->save($cactive)) echo "good!"; }
