i building java-servlet-based web application should offer service quite lot of users (don't ask me how "a lot" :-) - don't know yet). however, while application being used, there might occur long-taking processing on serverside. in order avoid bad ui responsiveness, decided move these processing operations own threads. means once user logged in, can happen 1-10 threads run in background ( per user! ). i once heard using multiple threads in web application "bad idea". is true , if yes: why? update: forgot mention application heavily relies on ajax calls. every user action causes new ajax call. so, when main servlet thread busy, ajax call takes long process. that's why want use multiple threads. it bad idea manually create threads yourself. has been discussed lot here in so. see this question example. another question discusses alternative solutions.

i wondering if there way capture state of iis6 app pool using directoryentry in c#? i have seen people use apppoolstate iis7 there equivalent work iis6? or need use different namespace? edit: there display string status? apppoolstate looks accepts integers. looks you'd use same property: check status of application pool (iis 6) c#

i have several ways solve this, interested in whether there better solution problem. please respond pure numeric algorithm. string manipulation not acceptable. looking elegant , efficient solution. given currency value (ie $251.03), split value 2 half , round 2 decimal places. key first half should round , second should round down. outcome in scenario should $125.52 , $125.51. divide two, round 2 d.p. (in c# decimal.round(value, 2) ), subtract rounded value original, , sort them using if. library may support control on rounding can save if - c# can using 3-parameter overload of decimal.round .

i have ui layer/ domainservice layer (domain logic , services reside here) , repo layer persistance, use ninject decouple things. i have kept ui layer simple - delegate tasks service layer, have complex application depends on loggedonuser, therefore crud can quite complex. my problem though is: have service , connects onto genericrepository. for example iorder communicates idbrepo order info depending on client accesses order, have ishipping - connects idbrepoand retireves info... gets complicated when 1 service needs call service, both connected idbrepo. i have managed pull out iusersession , can give each service - seems complicated me... when setting test have like: var db = new dbrepo(); var s1 = new orderservice(db); var s2 = new shippingservice(s1,db); then extend some/most of services have add iloggingservice , inotificationservice - both need access database too... note: not looking pure ddd, trying take best of things , make work guess has been problem....

the color schemes in emacs shell mode appear primary colors (high saturation) , primitive, , colors, example, purple, not appear: i want adjust colors use more intermediate colors , more soft in gnome-terminal: how can change color schemes in shell mode? couldn't find shell-mode related font assignments in emacs, , because color given shell , different other font assignmets in emacs. when program run inside shell-mode issues ansi escape characters set display color to, say, magenta, emacs intercepts escape characters , creates colored overlay using exact foreground color "magenta". there's no color theme interaction going on here, , no shell-specific customizations for. the interception made functions in ansi-color.el , though, , looks customize ansi-color-names-vector , use "paleblue" "blue", either m-x customize ret ansi-color-names-vector , or try putting following in emacs config: (setq ansi-color-names-vector [...

for example bash: kill -9 -pid os.kill(pid, signal.sigkill) kill parent process. when pass negative pid kill , sends signal process group (absolute) number. equivalent os.killpg() in python.

i have written application. works fine on resolutions of controls on lapped when run on other computers. there way of setting application automatically when run on different computers? thanks furqan you might want take @ this: http://msdn.microsoft.com/en-us/library/ms229649.aspx (assuming not wpf) you can lot docking , anchoring form maintain it's usability @ different sizes. but, there practical limits. can enforce minimum size , ensure controls resize appropriately down limit.
