c# - Check if File Exists on Remote Machine via Console Application -


first - still relatively new .net development. now, since that's out of way. making reporting console application go , access remote machines , check see if .png exists on every machine , report if image there or if there error, , error's message. reading in csv of ip addresses. currently, application read csv list. then, iterate on list appending ip address beginning of file path(i.e \\10.155.191.239\c$\programstuff\blahblah\storepcmenu\data\myassets\app_icons.png). @ beginning of console app, elicit user credentials. using .\desktop user credentials should sufficient trying do.

my problem > application reporting false negatives. also, if remote machine denies credentials, shows me generic error message , not message pertaining credentials denied.

we using pinvokewindowsnetworking class validate credentials. however, couldn't figure out how class report whether or not credentials actual problem. so, included managementscope class, able show me whether or not credentials validated (while using credentials other .\desktop). however, managementscope class not seem want work .\desktop credentials.

foreach (mystruct record in mylist) {     try     {         //managementscope myscope = new managementscope("\\\\" + record.myip + "\\root\\cimv2", myoptions);         managementscope myscope = new managementscope("\\\\"+ record.myip + "\\", myoptions);         myscope.connect();         if (myscope.isconnected == true)         {             try             {                 logentry = pinvokewindowsnetworking.connecttoremote("\\\\" + record.myip, uname, pword);                 if (file.exists("\\\\" + record.myip +eopath ))                 {                     output.writeline(record.store + " ," + record.myip + ", yes");                     console.writeline(record.store + " ," + record.myip + ", yes, " + datetime.now.tostring("yyyy-dd-m--hh-mm-ss"));                 }                 else if (!file.exists(record.path))                 {                     if (logentry.contains("error"))                     {                         output.writeline(record.store + ", " + record.myip + ", no, " + logentry);                         console.writeline(record.store + ", " + record.myip + ", no, " + datetime.now.tostring("yyyy-dd-m--hh-mm-ss") + ", " + logentry);                     }                     else                     {                         output.writeline(record.store + ", " + record.myip + ", no, file not found");                         console.writeline(record.store + ", " + record.myip + ", no, " + datetime.now.tostring("yyyy-dd-m--hh-mm-ss") + ", file not found");                     }                 }             }             catch (exception ex)             {                 output.writeline(record.store + ", " + record.myip + ", no, " + ex.message);                 console.writeline(record.store + ", " + record.myip + ", no, " + datetime.now.tostring("yyyy-dd-m--hh-mm-ss") + ", " + ex.message);             }         }     }     catch (exception ex)     {         output.writeline(record.store + ", " + record.myip + ", no, " + ex.message);         console.writeline(record.store + ", " + record.myip + ", no, " + datetime.now.tostring("yyyy-dd-m--hh-mm-ss") +", " + ex.message);     }         {         if (!logentry.contains("error"))         {             pinvokewindowsnetworking.disconnectremote("\\\\" + record.myip);         }     }

any explanation of these 2 classes (other msdn links) or advice on use appreciated! need open , close socket between client , of these remote machines?

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
