spam - Checking form submission against a word list -


i have code check form being spammed , if stop email.

it includes section this:

if(strpos($messagefield, " cialis") !== false){ $noemail = true; } if(strpos($messagefield, " viagra") !== false){ $noemail = true; }

etc many words have in bad word list

this works fine, clumsy , difficult add new words check. easier if create array , check field against array, strugling find example use (most examples still specify text search defeats object in case)

can code check $messagefield against array?

(i know there better ways maybe works @ moment!)

$i = 0; $wordlist = array(' cialis', ' viagra');  while ($i < count($wordlist) && $noemail == false) {   if (strpos($messagefield, $wordlist[$i]) !== false) {     $noemail = true;   }   $i++; }

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...
