c# - Check record state of a database entry -


i'm writing hardware inventory application. data computer through wmi , write database linq.

eventually end record like:

id  hostname    os         memory     1  myhostname  windows 7  4gb

now imagine add memory computer , next time application finds it, have information computer updated , try write database.

before writing check if hostname present on database (it primary key), in case exists. now, query database hostname , information have computer , create object , compare object got wmi ?

isn't there way create value on table based on each record information , have linq create 1 based on wmi object , compare each other?

sorry if text little confusing, hope guys can me out this.

try this.

var entry = yourcontext.yourtable.singleordefault(e => e.hostname == somehostname);

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
