c# - Window Closing Event and KeyPress -

- 

<window closing="window_closing"></window>

assuming keys used close window. there way determine keys used?

i know can keydown event need in closing event.

thank you!

rather trying determine cause of closing event disable keystrokes, disable methods closing until "secret" keystroke entered.

use keydown event intercept , record keystrokes, , have set flag if secret combination entered, , call close().

in closing event, set e.cancel = true unless flag set.

here's simple example:

bool _allowclose = false;  void onkeydown(object sender, keyeventargs e) {     if (detectsecretcombo(e))  //implement see fit.     {         _allowclose = true;         close();     } }  void onclosing(object sender, closingeventargs e) {     _e.cancel = !_allowclose; }

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
