i customizing styles on web page better printing experience. i using print media query hide header, footer , nav pane. since size of container may change, trying dynamically scale main container fit paper , keep container's aspect ratio. works in chrome mediaquerylistener (calculate scaling factor based on current container size , paper size, , generate "@media print {.containerclass{transform: scale(0.3)}}" . append body). blocked on how in ie (always :-( ). i looking @ onbeforeprint , onafterprint , thought me. but turned out onafterprint happened after onbeforeprint before print dialog, means not technically after print . , when onbeforeprint gets called, media query hasn't been applied page yet. here problem, scale factor calculation based on paper size , current container size. paper size available when in print mode. seems cannot detect if current page in print mode in ie. do guys know how achieve in ie/edge?

i have question. have module following : define(['jquery', 'amodule', 'anothermodule'], function () { .... } lets assign above module name 'mymodule' in requirejs config file. in other file this: require(['myconfigfile'], function () { require['mymodule'], function(module) { } } do need require modules part of 'mymodule' definition in nested require statement well? no, requirejs 'translate' 'jquery', 'amodule', 'anothermodule' . in other words, first load modules 'jquery', 'amodule', 'anothermodule' before loading 'mymodule'

i trying add backlog items sprint using hansoft sdk. there function "hpmfunctiontask get linkedtosprint" gets id of sprint task linked. unfortunately there no function set sprint of task, in sdk. is there way commit item sprint? in gui looks this: thank you, ondras. i have got answer hansoft support. to add backlog item sprint have create proxy item: hpmtaskcreateunified proxytaskcreate = new hpmtaskcreateunified(); proxytaskcreate.m_tasks = new hpmtaskcreateunifiedentry[1]; hpmtaskcreateunifiedreference parent = new hpmtaskcreateunifiedreference(); hpmtaskcreateunifiedreference previous = new hpmtaskcreateunifiedreference(); parent.m_blocalid = false; parent.m_refid = sprint.uniqueid.m_id; // task reference id of sprint previous.m_blocalid = false; previous.m_refid = sprint.uniqueid.m_id; // task reference id of sprint proxytaskcreate.m_tasks[0] = new hpmtaskcreateunifiedentry(); proxytaskcreate.m_tasks[0].m_bisproxy = true; proxytaskcreate.m_tasks...

let's take simple case .net smtpclient, can following (ignoring credentials, ssl , exception handling): async task sendmail() { var m = new mailmessage(...); var s = new smtpclient(host, port); s.sendcompleted += (s, e) => { m.dispose(); s.dispose(); }; await s.sendmailasync(m); } all fine; func dispose()ing called whenever async sending finishes. m , s within containing scope declared, no problem there. but had following: smtpclient setupmailclient(mailmessage mail) { var smtpclient = new smtpclient(host, port); smtpclient.sendcompleted += (s, e) => { mail.dispose(); smtpclient.dispose(); }; return smtpclient; } async task sendmail() { var m = new mailmessage(...); var s = setupmailclient(m); await s.sendmailasync(m); } now, calling await sendmail() still safe? closure still valid? pass in reference mailmessage 'mail' - copy of reference, valid in context of setupmailclient(). overthinking it, or still safe...
