lync 2013 - Ucma4 Delayed Response when using PresenceServices BeginPresenceQuery -


on test machine , when sending request front end, have great response (two seconds). on production, request takes 30 sec or more , organization have more 5000 users. if have away sips status using ucma? ucwa cannot using. any idea ?

code :

public dictionary<string, string> getagentsavailability(list<string> usersuris) {     lock (lockobj)     {         agentsavailability = new dictionary<string, string>();         try         {             if (usersuris != null && usersuris.count > 0)             {                 iasyncresult agentavailabilitycheck = applicationendpoint.presenceservices.beginpresencequery(usersuris, new string[] { "state" },null, null);                 waithandle[] w = new waithandle[] { agentavailabilitycheck.asyncwaithandle };                 waithandle.waitall(w, 3000);            }             else             {                 writeentry.elog("platform - getagentsavailability - no agent sips check.", eventlogentrytype.information);             }         }         catch (exception ex)         {             writeentry.elog(ex.tostring(), eventlogentrytype.error);             throw;         }         return agentsavailability;     } }

for such large number of users i'd recommend using presence subscription inform of current presence , presence changes rather trying check presence of users @ once.

see following microsoft article on working presence , groups more details https://msdn.microsoft.com/en-us/library/office/hh456406(v=office.14).aspx

there's quite lot on above link functionality after centred on remotepresenceview class.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
