c# - asp.net Internet Explorer image cache? -


i'm writing asp.net app in c#. in program image of schedule grid has lines drawn on depending on selections user. when user selects day, image redrawn show scheduled time"lines" day. works fine in chrome, , firefox, in internet explorer(9) image won't change day, displays whatever first image regardless of day user selects afterward.

i used code on code-behind because thought caching image, didn't resolve issue. pointers?

response.cache.setnostore(); response.cache.setcacheability(httpcacheability.nocache);

(a standard clean grid image loaded, drawn on, renamed , saved different local folder. new image loaded image control on screen. happens every time user changes days.)

you refer ms's documentation on avoiding image caching:

http://msdn.microsoft.com/en-us/library/w9s3a17d(v=vs.71).aspx

and place in page_load method:

response.cache.setcacheability(httpcacheability.nocache)

but since naming file @ run time, name file differently each time (maybe using date since it's timeline), other images on page not cached.

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
