asp.net mvc - Server error: if (User.IsInRole("Administrators")) -


in mvc 4 internet application can't use this:

@if (user.isinrole("administrators"))

it result in error:

a network-related or instance-specific error occurred while establishing connection sql server. >server not found or not accessible. verify instance name correct , sql server >configured allow remote connections. (provider: sql network interfaces, error: 26 - error locating >server/instance specified)

this has been bothering me quite long time appreciated.

here stack trace:

edit: results in error when auto login.

in mvc user.isinrole or similar authorization methods trying use simplemembership provider default.

if using custom authorization need add below code web.config:

<system.webserver>   <modules>     <remove name="rolemanager" />   </modules> </system.webserver>

if using simplemembership make sure databases initialized.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
