delphi - cxgrid custom menuitem (open with) for Image field -


in cxgrid have column "image" type.(properties=image,graphicclassname=tjpegimage). popupmenulayout - menuitems have added custommenuitem called "open with...". how can implement custom menu item opens underlying image paint (windows paint)? or @ least trigger "open with.." windows dialog.

if have image stored in database first have save image file on computer.

then can use shellexecute opening image default image viewing/editing program. shellexecute works same if user have double-clicked on file. problem doublec-licking on image file opens preview of if need edit image using of shellexecute might not best way.

now in order sure image opened editing rathen in preview have read windows registry information program used viewing , editing of specific image format , use createprocess api cal instead.

you make sure image opened specific program starting program using createprocess api call , passing image location startup parameter (most image editing programs treat first parameter file open upon startup

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
