what recommend simple result "ismailvalid?" -> true|false? is save use regexp is better use .net's system...mail.mailaddressparser simple try/catch around it? since speed not relevant, think going way mailaddressparser ok? regards john given requirements speed not being necessary, use mail.mailaddressparser try/catch. it's guaranteed filter out .net runtime can't recognize valid email address, , simpler. a regex same, bad regex give false positives, false negatives, or both. the performance cost in handling exceptions make me go other way if speed factor, in case, requirements, less code, more readable code, , "just works" balance out performance factor. clarification: i'm assuming intended code this: try { system.net.mail.mailaddress address = new system.net.mail.mailaddress(somestring); } catch(exception ex) { // handle invalid email addresses here. } and recommendation situation. intentional except...

i using .net environment , wanted track expiration date found in credit cards. date there of nature "mmyyyy". recommended way store ? should use .net string or instead use .net datetime object ? in cases easiest solution best solution. easy maintain, easy other programmers recognize, , may keep out of trouble (ints , strings can lead localization problems , invalid values). a system.datetime best option , gives flexibility cards may expire on given day (they rare, exist, , may become more prevalent temporary credit cards becoming popular). when storing value use date property of system.datetime struct since disregard time components.

possible duplicate: when should deploy assemblies gac? how deploy applications? copy necessary dlls (your own, 3rd party, etc.) application folder , finished or deploy or dependent dlls gac is there best practice of above solutions use , dlls go application folder vs gac? i using clickonce. so, not worry versioning, gac , other stuff, create additional folders in project solutions copy 3-d party assemblies into, , not have of difficulties updates, besause easy implement custom update system using built-in update system , reflection (for custom versioning), can find information clickionce deployment , custom updates for simplicity, recommend use directory structure: <assembly set>\<assembly name>\<assembly version>\ for example: media\ui\1.0.0.0\ui.dll or assemblies\libvnc\1.11.10\libvnc.dll

possible duplicate: calling closure assigned object property directly why not possible in php? want able create function on fly particular object. $a = 'a'; $tokenmapper->tokenjoinhistories = function($a) { echo $a; }; $tokenmapper->tokenjoinhistories($a); with $obj->foo() call methods, want call property as function/method. confuses parser, because didn't find method name foo() , cannot expect property callable. call_user_func($tokenmapper->tokenjoinhistories, $a); or extend mapper like class bar { public function __call ($name, $args) { if (isset($this->$name) && is_callable($this->$name)) { return call_user_func_array($this->$name, $args); } else { throw new exception("undefined method '$name'"); } } } (there issues within written example)

i made program solve this problem acm. matchsticks ideal tools represent numbers. common way represent ten decimal digits matchsticks following: this identical how numbers displayed on ordinary alarm clock. given number of matchsticks can generate wide range of numbers. wondering smallest , largest numbers can created using matchsticks. input on first line 1 positive number: number of testcases, @ 100. after per testcase: one line integer n (2 ≤ n ≤ 100): number of matchsticks have. output per testcase: one line smallest , largest numbers can create, separated single space. both numbers should positive , contain no leading zeroes. sample input 4 3 6 7 15 sample output 7 7 6 111 8 711 108 7111111 the problem it's way slow solve 100 matchsticks. search tree big bruteforce it. here results first 10: 2: 1 1 3: 7 7 4: 4 11 5: 2 71 6: 6 111 7: 8 711 8: 10 1111 9: 18 7111 10: 22 1...
