c# - listbox selectedindex only selecting last element -


i have listbox bound list of objects database. have secondary list has less objects want use mark selected elements.

        cell = new htmltablecell();         list<clasaautor> listaautori = datatabletoclasaautor(dal.citestetotiautori());         list<clasaautor> listaautoripublicatie = datatabletoclasaautor(dal.citestetotiautoriuneipublicatii(guidpublicatie));         listbox list = new listbox();         list.selectionmode = listselectionmode.multiple;         list.id = "cbautori";         list.datasource = listaautori;         list.datatextfield = "numecomplet";         list.datavaluefield = "guidautor";         list.databind();         foreach (clasaautor autor in listaautoripublicatie)         {             (int = 0; < list.items.count; i++)             {                 if (list.items[i].value == autor.guidautor.tostring())                     list.selectedindex = i;             }         }          cell.controls.add(list);         row.cells.add(cell);

the problem last element gets selected... why? how can fix it?

my if ok, gets true 2 times...

try loop:

foreach (clasaautor autor in listaautoripublicatie) {     foreach (listitem item in list.items)     {         if (item.value == autor.guidautor.tostring())             item.selected = true;     } }

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
