is possible use backgroundworker thread in asp.net 2.0 following scenario, user @ browser's end not have wait long time? scenario the browser requests page, sendemails.aspx sendemails.aspx page creates backgroundworker thread, , supplies thread enough context create , send emails. the browser receives response composeandsendemails.aspx, saying emails being sent. meanwhile, background thread engaged in process of creating , sending emails take considerable time complete. my main concern keeping backgroundworker thread running, trying send, 50 emails while asp.net workerprocess threadpool thread long gone. if don't want use ajax libraries, or e-mail processing long , timeout standard ajax request, can use asynchronouspostback method "old hack" in .net 1.1 days. essentially have submit button begin e-mail processing in asynchronous state, while user taken intermediate page. benefit can have intermediate page refresh as needed, without worrying ...

i htmlcontrols because there no html magic going on... asp source looks similar client sees. i can't argue utility of gridview, repeater, checkboxlists, etc, use them when need functionality. also, looks weird have code mixes , matches: <asp:button id='btnok' runat='server' text='ok' /> <input id='btncancel' runat='server' type='button' value='cancel' /> (the above case in event wanted bind server-side event listener ok cancel runs javascript hides current div) is there definitive style guide out there? should htmlcontrols avoided? it might useful think of html controls option when want more control on mark ends getting emitted page. more control in sense want every browser see same markup. if create system.web.ui.htmlcontrols like: <input id='btncancel' runat='server' type='button' value='cancel' /> then know kind of code going emitted. though of t...

i have inherited medium sized rails application , want try optimize right away. want start database ensure indexes placed need forth. therefore need find out possible sql statements activerecord might make can compare database schema , see immediate optimization can made. in short: there equivalent rake routes output possible sql templates? the hard way the rails development log file should contain of sql used during execution of server. grep file select statements - perhaps getting little smarter using regexp. unfortunately you're unlikely ever able process of information therein manage exception a better way use simple monitoring solution alert when request runs (e.g. scout ). @ rails log file see if problem related db. use db tools most dbs alert via log file somewhere if query runs - mysql example has 'slow queries log'.

i'm haskell newbie , couldn't find answer question. can define types conditions? example, simple user-defined data type be: data mylist = mylist [a] can somehow modify code mylist constructor can take lists number of elements? data mylist = mylist [a] (even (length a)) thank you! no, can't. if it's necessary, write constructor-like function yourself. tomylist :: [a] -> mylist tomylist l | (length l) = mylist l | otherwise = error "length of list has even" or if error-checking occur: tomylist :: [a] -> maybe mylist but depending on use-case, maybe can express through types (e.g. tuples or 2 lists) through runtime-checks.

we rewriting our legacy accounting system in vb.net , sql server. brought in new team of .net/ sql programmers rewrite. of system completed dollar amounts using floats. legacy system language, programmed in, did not have float have used decimal. what recommendation? should float or decimal data type used dollar amounts? what of pros , cons either? one con mentioned in our daily scrum have careful when calculate amount returns result on 2 decimal positions. sounds have round amount 2 decimal positions. another con displays , printed amounts have have format statement shows 2 decimal positions. noticed few times not done , amounts did not correct. (i.e. 10.2 or 10.2546) a pro float takes 8 bytes on disk decimal take 9 bytes (decimal 12,2) should float or decimal data type used dollar amounts? the answer easy. never floats. never ! floats according ieee 754 binary, new standard ieee 754r defined decimal formats. many of fractional binary parts can neve...

i have uiimageview being rounded on custom drawn uitableviewcell: rect = cgrectmake(13, 10, 48, 48); avatar = [[uiimageview alloc] initwithframe:rect]; [self.contentview addsubview: avatar]; calayer * l = [avatar layer]; [l setmaskstobounds:yes]; [l setcornerradius:9.0]; i noticed uitableview scrolling performance decreased little bit. not sure if related rounded corners though? rounded corners slow down drawing lot. mask layers faster. "baking" corners content (as image or using clipping path in drawrect: ) faster still. allocating new views/layers slow down scrolling--reuse them wherever can (creating uitableviewcell subclass creates subviews in init , destroys them in dealloc works well) that being said, adding additional views shouldn't reduce performance noticeably.

best recommendations accessing , manipulation of sqlite databases javascript. well, if working on client side javascript, think out of luck... browsers tend sandbox javascript environment don't have access machine in kind of general capacity accessing database. if talking sqlite db on server end accessed client end, set ajax solution invokes server side code access it. if talking rhino or other server side javascript, should host language's api access sqlite (such jdbc rhino). perhaps clarify question bit more...?
