c# - ExportToHttpResponse - Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack -


i'm attempting open crystal report in new window. settled on javascript open page in new window so:

 clientscript.registerstartupscript(this.page.gettype(), "",               "window.open('reportwindow.aspx?" + thequerystring + "','_blank');", true);

this works fine, new window opens, etc.

from new window use line generate report:

contractlevelreport.exporttohttpresponse(crystaldecisions.shared.exportformattype.portabledocformat, response, false, "contractlevelreport");

again, works... kinda. in debug generates report, catch exception listed in subject line. if f5 (continue) on through report shows. when publish web error causes hang.

i suspect new window bumping against response.end needs happen , causes hang.

i've tried following line in couple of places.

httpcontext.current.applicationinstance.completerequest();

... not seem work.

if calling using response.redirect tell end current request, javascript window.open messes up.

suggestions?

thanks!

update:

if leave out javascript portion , generate report current window error still thrown (threadabortexception), continues , shows pdf report anyway.

something 2nd window , how cr forces response.end causing problem... not sure how resolve it.

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
