.net - 32 and 64 bit assemblies in one windows installer -

-

i have application written in c# depends on sqlite managed provider. sqlite provider platform dependent (there 2 dlls 32 , 64 bit applications same name). application loads desired 1 @ runtime based on os.

the problem while creating installer cannot add 64 bit mode dll setup project getting following error: file '' targeting '' not compatible project's target platform ''.

i use other installer have custom action must invoked during setup.

so wanted know if there installer let me add 32 , 64 bit dll , execute custom action written in c#.

one possible solution have 2 installers avoid if possible.

any suggestions?

the inno setup installer support feature wich request, installer flexible , reliable, exist many samples of scripts in web make conditional installation depending of architecture of final client.

check script located in c:\program files\inno setup 5\examples\64bitthreearch.iss

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
