i'm new borland c++ builder , application i'm working on has launched asp.net application on click of button. asp.net application able launch other exes (made in c#) when application launched crashes msg "an error has encountered, please tell microsoft problem" button "don't send" "send error report" , "debug". asp.net program able call "notepad.exe" not written on .net. so, how call application asp.net/c# written in borland c++ builder , launching when double click application. can check event log more information on caused error, guess cannot load c++ dll.

i have 2 pieces of windows technology i'd plumb together: tsp ( a tapi service provider ) , api wrapped around hardware. api accepts requests synchronously returns success/fail/status result asynchronously sending messages passed-down hwnd. as understand it, problem because tsp runs windows service, execution context doesn't have access interactive windows functions. so, i'd directly link 2 together, can't - far can tell, tsp doesn't ( and indeed couldn't ) have hwnd api send messages to. :-( for me has ever programmed windows stuff on 1 side of service/interactive line @ time, of bit of head-scratcher. windows being way is, there must several sensible ways of getting messages across line, surely? how advise me try hook these 2 things? thanks! :-) a service can create "message window" (a window whos parent hwnd_message) , run message pump. message window has no ui , therefore doesn't interact desktop.

according rest philosophy, put request should update resource @ url if exists, , create if doesn't exist. in other words, if use following url: put http://server/item/5 if item exists id of 5, updated. if item doesn't exist id of 5, new item created id of 5. however, i'm using nhibernate persistence, , mapped ids identity . means no matter value assign id, nhibernate replace own when save new item . how nhibernate save item id assign it, without changing id mapping assigned ? if use identity, db won't allow enter value. that said, if db has special syntax allow inserting explicit values in identity fields, can implement own generator, guarantee error prone, hard debug, , not useful. it's possible. study in https://nhibernate.svn.sourceforge.net/svnroot/nhibernate/trunk/nhibernate/src/nhibernate/id , start creating frankenstein :-)

are there javascript wrapper scripts available can use html5 javascript features if available (e.g. locastorage / web storage / in common between google gears , html5), falling google gears if browser not capable (e.g. ie6 or ie7) while ideal ie7/6 users move ie8 (or chrome, firefox, opera), still around years come (maybe ie6 not last long ie7, ie7 lacks real javascript changes). for feature detection think here recommend excellent modernizr . of course you'd still have write gears part yourself, isn't hard - secondary test after modernizr reporting features you're looking isn't available, or creating own test addtest() api . it comes across little odd you're trying use gears fallback html5 components - far can tell, gears penetration very low, can't reliable fallback those. although functionality similar, syntax isn't, going writing twice amount of code that's unlikely used.

how can hide row @ specific index of datagrid in as3 ? if dataprovider of datagrid arraycollection can specify filterfunction property it, that dataprovider.filterfunction = function (item:object):boolean{ if (dataprovider.getitemindex(item)==indexofrowyouwanttohide){ return false; } return true; }; the item still in arraycollection made invisible filter. not efficient solution works. need call dataprovider.refresh(); to apply filter. update: access raw, unfiltered data of arraycollection should use list property, if hid item @ index 0 , still want able access this: dataprovider.list.getitemat(0);

it's commonly understood in relational model: every relational operation should yield relation. relations, being sets, cannot contain duplicate rows. imagine 'users' relation contains following data. id first_name last_name 1 mark stone 2 jane stone 3 michael stone if runs query select last_name users , typical database return: last_name stone stone stone since not relation - because contains duplicate rows - should ideal rdbms return? "but information lost - there 3 users last name." if count of users name interested in, query of example not question should asking. the query of example provide answer question "what last names such there exists user has last name ?". if question want ask "how many users there named 'stone'", query should submit select count(...) users last_name = 'stone'; projection always "looses" information. information tied attributes projecte...
