possible duplicate: declaring variable inside or outside foreach loop: faster/better? hi all, what difference between 2 examples or there any? ex 1: for (int = 0; < 2; i++) { thread newthread = new thread( ... ); newthread.start(); } ex 2: thread newthread; (int = 0; < 2; i++) { newthread = new thread( ... ); newthread.start(); } their il codes same... in second example, can access last thread newthread , not possible in first example. one more difference: second example holds reference last thread, garbage collector can't free memory when thread finished , disposed. the new keyword allocates memory, there no difference in memory allocation (see this link ).

problem description: have iseries query in vb.net/vs 2008 need run 2 separate values of same parameter , present in report a/b comparison. in other words - want see report result of run parameter = value1 on left, same query parameter = value2 on right. my initial idea use 2 tables on report each table based on result of each run dataset (xsd), seem able specify parameters on reportviewer level, means have 2 identical tables instead of a/b cases. obvious second way create 2 separate reports, each own parameter value , them subreports onto main one. however, both subreports show "error: subreport cannot shown". there way catch error see why? i did few other experiments, have problem fact it's not "neat" solution. what best way (a.k.a. best practices, industry standard, whatever want call it) create kind of a/b report? sure there well-known method make work, surprise haven't found except multiple copies of msdn articles. to use 2 reports s...

i have list of names here apple.fruit appleorder2.fruit orange.fruit i want extrat fruit name expected apple apple orange i have regex (.*)((order)|(\.fruit)) that returns @ position one, apple appleorder2 orange i think \. messing alternation character because when did test using (.*)((order)|(ge)) the alternation works fine returning @ position 1 empty apple oran perl being used use lazy quantifier: (.*?)(order|\.fruit) in regex, .* first matches entire string, backtracks 1 character @ time until alternation order|\.fruit matches. since that's case after 6 backtracks already, regex engine never gets point might find other, earlier alternative. solution: tell regex engine match few characters possible adding ? quantifier.

i've duplicated elements in datastore (not whole row, of fields on it) in app engine. what's best way find them? i've both integer , string fields duplicated (in case comparing 1 faster other). thanks! an stupid quick approach take fields care about, concatenate them long string , store them key of db_unique entity references original entity. each time db_unique.get_or_insert() should verify reference correct original entity, otherwise, have duplicate. should done in map reduce . something like: class db_unique(db.model): r = db.referenceproperty() class db_obj(db.model): = db.integerproperty() b = db.stringproperty() c = db.stringproperty() # executed each db_obj... def mapreduce(entity): key = '%s_%s_%s' % (entity.a,entity.b,entity.c) res = db_unique.get_or_insert(key, r=entity) if db_unique.r.get_value_for_datastore(res) != entity.key(): # have possible collision, verify , delete? # out 2 entities res , entity th...

i issue following sql: select * mytable myid =123 , mydate >= (case when isnull(null,'')='' mydate else null end) performance pretty bad. if modify this: select * mytable myid =123 , mydate >= mydate the performance better. my real sql like: select * mytable myid =123 , mydate >= (case when isnull(@mydate,'')='' mydate else null end) mydate datetime column. how improve performance case? if t-sql then: declare @mydate datetime set @mydate = null if @mydate not null begin select * mytable myid = 123 , mydate >= @mydate end else begin select * mytable myid = 123 , mydate >= '' end else param'd sql: select * mytable myid = 123 , (@mydate null or mydate >= @mydate) edit: added not if condition.

i have function allocates memory using new keyword. that array gets returned function, need somehow free it. ever freed after function returns, or receiving code free array after done it? should make array member variable, , free in class destructor? it depends. need define has got ownership of such object. you can allocate array in function, return it, , let caller free it, or put pointer in class destroy pointer in destructor. if ownership such object should shared among many entities should use shared_ptr . i'd suggest use kind of smart pointer handle raw pointers.

i want create bookmark send parameter querystring such author=john smith inserted rails app, have far correct? providing find out how url parameters function updatedata(param) {   var myurl = 'http://localhost:3000/app/book';   http.open("get", myurl + "?author=" + value-of-querystring-param, true);   http.onreadystatechange = usehttpresponse;   http.send(null); } that looks should work, presuming usehttpresponse handler function. one thing should encode parameter: http.open("get", myurl + "?author=" + encodeuricomponent(param), true);

so in bufferedimage , receive single integer has rgb values represented in it. far use following rgb values it: // rgbs array of integers, every single integer represents // rgb values combined in way int r = (int) ((math.pow(256,3) + rgbs[k]) / 65536); int g = (int) (((math.pow(256,3) + rgbs[k]) / 256 ) % 256 ); int b = (int) ((math.pow(256,3) + rgbs[k]) % 256); and far, works. what need figure out how integer can use bufferedimage.setrgb() , because takes same type of data gave me. i think code like: int rgb = red; rgb = (rgb << 8) + green; rgb = (rgb << 8) + blue; also, believe can individual values using: int red = (rgb >> 16) & 0xff; int green = (rgb >> 8) & 0xff; int blue = rgb & 0xff;

can 1 explain conceptual difference between both of them. read somewhere second 1 creates new array destroying references existing array , .length=0 empties array. didn't work in case //declaration var arr = new array(); the below 1 looping code executes again , again. $("#dummy").load("something.php",function(){ arr.length =0;// expected empty array $("div").each(function(){ arr = arr + $(this).html(); }); }); but if replace code arr =[] in place of arr.length=0 works fine. can explain what's happening here. foo = [] creates new array , assigns reference variable. other references unaffected , still point original array. foo.length = 0 modifies array itself. if access via different variable, still modified array. read somewhere second 1 creates new array destroying references existing array that backwards. creates new array , doesn't destroy other references. var foo = [1,2,3]; var bar = [1...
