i have winforms c# app displays tabular data db gridview control. i need programmatically add final column tickbox each row, in order find out rows have been ticked form current view. how go doing that, tickbox column not exist in db? you add column directly datasource before binding datagridview. supposing using datatable datacolumn dc = table.columns.add("select", typeof(bool)); dc.defaultvalue = false; grid.datasource = dt; another method define datagridviewcheckboxcolumn() , append current column list checkcol = new datagridviewcheckboxcolumn(); checkcol.headertext = "select"; checkcol.width = 80; checkcol.readonly = false; grid.columns.add(checkcol);

so problem having appears bug occurs on linux. i'm trying have swing app record when key pressed down, detect when key released. shouldn't in issue because keylistener supposed handle me. the problem when hold key down lots of repeated keypressed()/keyreleased() events instead of single keypressed(). have solution or workaround knowing when key released on linux? thank you. so problem having appears bug occurs on linux yes linux problem. on windows when key held down multiple keypressed events single keyreleased event. this question asked , i've never seen solution. but think basis of solution use timer. when key pressed start timer. when keypressed restart timer. long timer interval greater repeat rate of key board timer continually reset when key held down. when keypresses stop being generated timer fire assume key has been released. implies have delay in processing keyreleased.

i'm trying create chrome packaged app complicated web app. i'm getting error: refused execute inline event handler because violates following content security policy directive: "default-src 'self' chrome-extension-resource:". note 'script-src' not explicitly set, 'default-src' used fallback. how explicitly set policy in manifest.json? i've tried things like: "content_security_policy": "default-src 'inline'; script-src 'inline'" but still same error message. syntax wrong, or error red herring? you can't loosen default csp in packaged app. if you're doing <button id="foo" onclick="dosomething()"> should instead include separate js file in html document.queryselector("#foo").onclick = dosomething; in onload handler. comply csp , make app more resistant xss attacks.

(minx=x1,maxx=x2) : (minx=x2, maxx=x1); and don't need first 2 pairs of parentheses. also check question .

i reconized numpy can link blas, , thought of why not using gpu accelerated blas library. did use so? update (2014-05-22) amd has produced beta release of amd core math library (acml) version 6.0 can offload fft , blas functions gpu using clmath internally. announcement here: acml beta 6.0 release leverages power of heterogeneous compute . caveat here input data must transferred cpu gpu , output data returned cpu on each blas or fft call. therefore, amd has bunch of scripts tuning when problem large enough acml use gpu instead of cpu. for sake of completeness, i'll mention nvidia supports similar functionality nvblas library relies on cublas , cuda won't work on nvidia gpus. original answer unfortunately, amd's gpu accelerate blas library cannot directly link numpy or other application expecting standard cpu-based blas library. reason existing gpu blas libraries require 1 first copy matrices gpu before calling blas functions. requires modify n...

as understand, update object couchdb. have send whole object since "inserting" new revision same id. neat , works quite well. but have problem, i'm not sure how should handle that. have object can't sent user completely. have hide informations such password hash. the data sent client, revision sent too. when try update object have 1 problem. since data missing, update erase attributes missing user. that said, easiest way have object couchdb, check if id , rev matches. if match, merge object missing attributes. work pretty , can support deleting attributes too. then using technique, add objects cache reduce time query frequent objects database. if object can updated, clear cache id. if object newer, i'll have handle error or merge object. is there better "good way" handle problem? edit after thinking during night, think found much better solution. instead of having username , password inside profile. i'll separate identification obje...
