c++ - Multithreading in VS2010 -


i have c++ dll created in vs2010. dll responsible generating report , sending server. dll called application creates data. since sending file server takes time so, don't want calling application wait till dll busy in sending file server.

to deal above-mentioned issue, want assign task of sending file server (just 1 small function) separate thread , not want wait thread complete (otherwise no benefit). 

while(usershutdowntheapp) {     - main app gather data      - main app call data management dll , pass data         - datamanagementdll: generate report         - datamanagementdll: start thread , send report server thread. not wait thread complete     - main app finishes iteration , going enter next iteration.     }

since, not have control on main calling application, can make modifications inside dll. confused how should implement logic? mean, happens if thread has not completed task of sending file server , meanwhile main calling application has called dll second time.

you should add bit more logic dll. first of all, call dll should not directly sends data server, queue task (simply add passed data internal queue). dll can have internal worker thread should responsible processing queue of tasks.

how internal implementation , architecture should like, depends on existing api (is modifiable or not).

hint - please take @ dllmain() https://msdn.microsoft.com/en-us/library/windows/desktop/ms682583(v=vs.85).aspx - should helpful entry point.

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

i'm integrating okta own idp server using okta's api. i'm implementing authorization code flow following steps below: in own server, use /api/v1/authn endpoint sessiontoken. use sessiontoken obtain authorization calling endpoint: /oauth2/v1/authorize?client_id=" + clientid + "&sessiontoken=" + sessiontoken + "&response_type=code&response_mode=query&scope=openid&redirect_uri=" + redirecturl + "&state=evanyang&nonce=" it's supposed return response status code 302 , location header containing redirect url code value. however, keep getting response status code 200 , without location header, html body saying "you using unsupported browser." , "javascript disabled on browser." according api documentation: http://developer.okta.com/docs/api/resources/oidc.html#authentication-request , sessiontoken parameter sufficient this: an okta one-time sessiontoken. allows api-based

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
