hangs when execute powershell script using php -

-

when tring run powershell script using $out = shell_exec('powershell.exe -command c:\xampp\htdocs\web\ping.ps1 < nul'); echo $out;

it hangs , noting done , page keep loading , that's simple script 

ping 8.8.8.8 -t

i used command in powershell in order allow executing scripts @ first ,

set-executionpolicy remotesigned -scope currentuser

but nothing changes . need , how execute powershell scripts using php ?

this happening because tag -t gives command prompt command continue pinging until it's interrupted.

the constant loading php executing power shell script , waiting said script stop executing before continuing. because power shell script never stops until navigate away page. it'll load

so interruptions php memory being maxed out , failing. or user navigates away page halts execution. please review

i recommend using count capturing input after execution

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
