c++ - enumerate child windows doesn't function, but enumWindows does...? -


heading

i don't know why, when start enumerating windows, goes correctly, enumerating child windows not enter function... , moves around code... if put hwnd = 0 runs... have no idea why not hwnd find child windows.

enter code here #include "stdafx.h" #include <windows.h> #include <iostream> using namespace std; hwnd h; int wpoc, chpoc; static bool callback enumwindowsproc(hwnd hprog, long lparam) {     wpoc++;      cout << wpoc << ": " << hprog << endl;     if(wpoc == 5) h = hprog;     if (wpoc > 20) return false;     return true; } static bool callback enumchildproc(hwnd hprog, long lparam) {     chpoc++;     cout <<"ch "<< chpoc << endl;     if (chpoc > 20) return false;     return true; } void search() {     wpoc = 0;     bool procsuccess;     procsuccess = enumwindows((wndenumproc)enumwindowsproc,null); } void searchmap() {     chpoc = 0;     bool procsuccess;     procsuccess = enumchildwindows( h,(wndenumproc)enumchildproc,null); }  int _tmain(int argc, _tchar* argv[]) {     search();     searchmap();      return 0; }

i made simple code find mistakes , same... don't know wrong... help.

it's not work you, because found window no childrens. debug stuff. paste breackpoint after serach(), see value of h. open spy++ , find handle same value h. see if window has childrens. possible output:

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
