c# - SignalR disconnect not being called on internet disconnection/re-connection -

i using signalr in app.i have app depends great grade on ondisconnected() beingness called correctly. , called correctly under next circumstances:

public task ondisconnected() { seek { deleteuser(context.connectionid); homecoming null; } grab (exception ex) { homecoming null; } } the user refreshes page the user navigates new page the user closes browser

however, not called if network connection drops. instance, if unplug network cable on client machine, or disable client's wireless network, or unplug router, ondisconnected() never called, after several min wait.

it raise disconnected not immediately. there's configurable threshold (30 seconds default) signalr wait (after underlying tcp connection has gone away , isn't immediate either) before considers client disconnected. if connection drops , reconnects before configured timeout won't raise ondisconnected.

if you're never seeing beingness raised in scenario after waiting while might bug. signalr 1.0 released today i'd encourage seek , see if still see problem.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
