my question how send key's application application running in background? let's made shortcut left arrow key alt+s, , want whenever i'm in application , when press alt+s background application response shortcut , send opened program left arrow key. here code made in embarcadero c++ 2010 simulate arrow left when pressing alt+s every 200 milisecond's: void __fastcall tform1::timer1timer(tobject *sender) { bool bbothpressed = getasynckeystate(vk_menu) && getasynckeystate(0x53); if(bbothpressed){ // showmessage("control!"); keybd_event(vk_left, 0, 0, 0); } } ... , work fine application, want know how include code global scope (any application), not application. i encourage use registerhotkey instead of getasynckeystate. way won't need loop nor timer, making application more reliable , responsive. to simulate keypresses application/window, need to: a) focus specific window: bringwindowtotop(hwnd); ...

my website uses linq-to-sql load 50k rows of data database. data static , never changes. works similar spam filter , 50k rows of patterns need loaded. what's best way program this? optimal performance? loading entire thing single static readonly data-structure (it being immutable means once constructed can safely used many threads) give greatest overall performance per lookup. however, lead long start-up time, may not acceptable. in case may consider loading each item accessed, brings concurrency issues (since mutating data-structure used multiple threads). in between option of loading indices on start-up, , adding rest of information on per-access basis, finer-grained locks reduce lock contention. or can ignore lot , load database needed. have advantages in terms of performance because memory not used rarely-used information. it'll whole lot easier if ever find have allow data change. no 1 comes out reasonable way go in general, it'll depend on speci...

i've got array of d unique (int, int) tuples. i need know if array contains (x, y) value. am implement search algorithm myself or there standard function in scala 2.8? i've looked @ documentation couldn't find of such there. that seems easy (unless i'm missing something): scala> val = array((1,2),(3,4)) a: array[(int, int)] = array((1,2), (3,4)) scala> contains (1,2) res0: boolean = true scala> contains (5,6) res1: boolean = false i think api calls you're looking in arraylike .

how can modify gap between lines in multiline uilabel ? edit: evidently nsattributedstring it, on ios 6 , later. instead of using nsstring set label's text, create nsattributedstring , set attributes on it, set .attributedtext on label. code want this: nsmutableattributedstring* attrstring = [[nsmutableattributedstring alloc] initwithstring:@"sample text"]; nsmutableparagraphstyle *style = [[nsmutableparagraphstyle alloc] init]; [style setlinespacing:24]; [attrstring addattribute:nsparagraphstyleattributename value:style range:nsmakerange(0, strlength)]; uilabel.attributedtext = attrstring; nsattributedstring's old attributedstringwithstring did same thing, that being deprecated. for historical reasons, here's original answer: short answer: can't. change spacing between lines of text, have subclass uilabel , roll own drawtextinrect , create multiple labels, or use different font (perhaps 1 edited specific line height, see p...

how read number of files in specific folder using python? example code awesome! to count files , directories non-recursively can use os.listdir , take length. to count files , directories recursively can use os.walk iterate on files , subdirectories in directory. if want count files not directories can use os.listdir , os.path.file check if each entry file: import os.path path = '.' num_files = len([f f in os.listdir(path) if os.path.isfile(os.path.join(path, f))]) or alternatively using generator: num_files = sum(os.path.isfile(os.path.join(path, f)) f in os.listdir(path)) or can use os.walk follows: len(os.walk(path).next()[2]) i found of these ideas this thread .

in d, main function defined: void main(/*perhaps args not remember*/) { } i know sure function returns 0 on success , non-zero on failure , yet defined not returning anything. logic behind it? function void return type not return value. there nothing illogical when consider call stack looks this: os -> d runtime -> main the main function invoked d runtime system, recognized main function returns nothing - , in case return success os. in case main function defined return type int, d runtime return os value returned main function.

when travel between files using shortcut on pathfile, seems don't travel between files. i go file using >, within file change location of cursor , something, press <. instead of going previous file, first goes original location @ when entered file, need press < again previous file. that's nuisance doesn't allow me change stored location within destination file. remains same enter @ same place, plus requires 2 clicks travel when 1 necessary. , makes system behavior more confusing. this problem seems arise when enter large files. small ones location works fine. how make < button move me previous file in, directly, always? p.s. use following mapping in vimrc: noremap > gf noremap < <c-o> have tried substituting <c-o> <c-6>, doesn't work, reason. you can use :bp in mapping (previous buffer): :noremap < :bp<cr>
