i have 2 web application projects (project , project b) in same solution. i want able to: through project a, save file somewhere in directory of project b. whenever use server.mappath etc, resolves virtual directory of project a, not of b. from reading, believe should able type url of project b directly save method. however, neither project deployed @ moment. besides, want leverage fact on same solution. tia! but if you're saving file , don't want access virtual directory ; want actual (physical) directory . means request.mappath way go; can use overload cross-app mapping set true . string pathtoappb = request.mappath("/appbvirtualpath", request.applicationpath, true); you still have know virtual path application b deployed to, though; , can't test locally unless deploy local iis.

Your way to write simple comments -

-
how guys write comments on simple code use yourself? i write javascript , php code, , can't feel found nice way write comments. if have short line of code, this: x = dothis(getsomevaluefromsomewhere()); // short line of code which seems nice think, doesnt works when line gets little longer or on multiple lines, // dont since it's not clear if describes line 1, or lines. alongervariablename = (getsomevaluefromsomewhere() == "this want") ? "true value" : "false value"; x = dothis(alongervariablename); so, how do it? (* * blocks of comments serve important documentation * e.g descriptions of functions. *) maybe reformatted as (* blocks of comments thet serve important documentation * e.g descriptions of functions. *) and // short inline comments do. don't forget ctrl-/ friend ;-)

bash - Test file existence with exit status from gnu-find -

-
when test -e file not flexible enough, tend use following bash idiom check existence of file: if [ -n "$(find ${find_args} -print -quit)" ] ; echo "pass" else echo "fail" fi but since interested in boolean value, there ${find_args} let me instead: if find ${find_args} ; ... i'd no. man find ... find exits status 0 if files processed successfully, greater 0 if errors occur. deliberately broad description, if return value non-zero, should not rely on correctness of results of find. testing output fine find. isn't "bash idiom". if that's not enough , have bash available can use extglobs , possibly globstar file matching tests [[ . find should used complex recursive file matching, or actual searching files, , other things can't done bash features.

regex - How to match a minimal pattern ending at the end of input in JavaScript? -

this follow-up previous question i find minimal sequence of characters of length > n , starts @ word boundary , ends @ end of input. for example: n = 5, input = "aaa bbb cccc dd" result = "cccc dd" i tried \b.{5,}?$ matches whole input rather minimal part. what regex suggest? the problem time isn't greediness, it's eagerness. regexes naturally try find earliest possible match, , getting them find last 1 can tricky. easiest way 1 @arcadien demonstrated: use .* gobble whole string, use backtracking find match on rebound. i have questions requirements, though. \b can match beginning or end of word, if (for example) n=5 , string ends "foo1 bar2" , result " bar2" (notice leading space). want match starts @ end of word, or should drop space or beginning of "foo1" ? also, words consist entirely of word characters? if there non-word characters, \b able match in more surprising places. for ...

java - GC collects referenced object after return from scope -

-
i have question how gc works in java. consider following code: class c1 { arraylist<int> mylist = new arraylist<int>(); public void setlist(arraylist<int> l) { mylist = l; } } func(c1 c) { arraylist<int> l1 = new arraylist<int>(); l1.add(1); c.setlist(l1); } main() { c1 c = new c1(); func(c); ... } my question is: gc releases 'l1' after func() returns or not? no, doesn't, because there's root reference (stack variable c ) has strong reference ( mylist ), new arraylist . after main() returns, c1 , arraylist collectible, because root reference disappears.

i have made jsfiddle: http://jsfiddle.net/grezzo/jr2lu/ when hit key on keyboard, picture flips around show text, during flip animation flickers (particularly text flickers) when viewed in chrome.

winforms - Datagridview excessive memory usage -

-
i have unbound datagridview 175 columns , 50,000 rows, populated doubles. according calculations, equates memory usage of 175*50000*8 bytes = 70 mb. however, task manager says grid using 1.2 gb of memory - 17x overhead! can explain why it's consuming memory? from msdn article on scaling datagridview ( http://msdn.microsoft.com/en-us/library/ha5xt0d9.aspx ) don't think i'm doing flagrantly wrong. i'm not setting styles or contextmenustrips individual cells. no modifications other populating cell values , setting format strings on column level. i understand virtual mode or shared rows might decrease memory consumption, given above calculations, don't think should necessary. 17x overhead doesn't sound right me. keep in mind each cell of datagridview holds datagridviewcell instance, containing 33 properties . it's more overhead double value.
