so, have rails webapp utilizes subdomains separating admin functionality public functionality using subdomain-fu. there functionality(that want test!) contained within 2 urls(eg admin.example.com , www.example.com ). want scenarios run against admin domain, , against www domain. my problem cant figure out how change domain selenium uses @ time after startup. can put in env.rb: webrat.configure |config| config.mode = :selenium config.application_address = "admin.example.com" end and work, scenarios need admin domain. if try like: host! "www.example.com" inside steps, seems ignored selenium, goes on using "admin.example.com" any ideas? or if not possible, ideas workaround? i haven't got working using webrat cabybara following works me. given /^i visit subdomain "(.+)"$/ |sub| # host!

it's bit complicated one... lets have listing of pdf files displayed in user's browser. each filename link pointing not file, asp page, say <--a href="viewfile.asp?file=somefile.pdf">somefile.pdf</a> i want viewfile.asp fetch file (i've done bit ok) want file loaded browser if user had opened pdf file directly. , want open in new tab or browser window. here's (simplified) viewfile.asp : <% var fileid = request.querystring ("file") ; var responsebody = mygetrequest (someurl + fileid) ; if (myhttpresult == 200) { if (extractfileext (fileid).tolowercase = "pdf") { ?????? // return file contents in new browser tab } .... %> as daniel points out can control whether open in new window not new tab. if user has configured browser new windows should open in new tabs (like do) you're golden. if not open in new window. can't control tabs.

what best way keep track of eventlistener function s on dom elements? should add property element references function this: var elem = document.getelementsbytagname( 'p' )[0]; function clickfn(){}; elem.listeners = { click: [clickfn, function(){}] }; elem.addeventlistener( 'click', function(e){ clickfn(e); }, false ); or should store in own variable in code below: var elem = document.getelementsbytagname( 'p' )[0]; function clickfn(){}; // using window sake of brevity, otherwise wouldn't =d // dom elements , listeners referenced here in paired array window.listeners = [elem, { click: [clickfn, function(){}] }]; elem.addeventlistener( 'click', function(e){ clickfn(e); }, false ); obviously second method less obtrusive, seems intensive iterating through possibilities. which best way , why? there better way? as other answers have mentioned, since tagged question jquery, doesn't make sense you're trying add , track events...

basically has said has been said in title. how make window other default 1 pop when insert pen drive pc? can come program in usb well? not doing actual coding yet. btw- if default window al options has special name plz tell me. can word google searches better. appreciated. thx if default window al options has special name plz tell me ‘autoplay’. can come program in usb well? no. ‘autorun’ program on usb device come 1 option on autoplay window. user must select run it. it used autorun programs executed automatically under default settings. was, obviously, total security disaster. after years of flash-drive viruses disabled in vista, leading current option-in-autoplay situation.

i'm trying find if window specific has been open process. process spawns multiple windows, , need check them all. i have no trouble finding process, with foreach (process p in process.getprocesses()) { if (p.mainmodule.filename.tolower().endswith("foo.exe")) findchildwindowwithtext(p); //do work the problem next. cannot use process' mainwindowtext , because changes whichever window activated. then i've tried use windows function enumchildwindows , getwindowtext , not sure if i'm passing correct handle enumchildwindows. enumchildwindows works expected when passed mainwindowhandle, of course mainwindowhandle changes active window. passed process.handle , different handles , different results when switching app's windows. (i understand enumchildwindows returns handles not windows , controls in .net speak, that's no problem if caption of window too) maybe doing wrong way , need different approach - again, problem simple finding wind...

i have series of images generated @ servlet. want show images on jsp page. want show images in way jsp page not refreshed image gets refreshed , replaced new one. thought of doing of applet or ajax. still looking convenient way of doing it. can suggest way of doing it? appreciated. thanks in advance. i'd go javascript if you. should pretty simple have list of images , set timer change source of image tag every second (or whatever). don't need "real" ajax that... changing attributes in dom. admittedly may not great if images take while load - might want have cunning mechanism load all images beforehand, , change 1 visible @ 1 time, or that. still shouldn't need ajax or applet though. i'm not sure i'd describe "video-like" experience - more slide-show - should okay. if want real video, use video :)

i'm using alarm manager trigger intentservice every hour. however, alarm gets registered when user runs app. problem when user opens app again makes manager create new service run , if current service running trip on each other because of database connection , dies! another problem alarm service stops. why? thought alarm should go on every hour no matter what! at beginning check existing database . if doesn't exist. make database , start alarm. next time app start if found database not start alarm again. or use saved value use semaphores check value 0 or 1.. rest functionality of alarm manager supposed work

i understand these client-side apps, 3 must based on component of computer itself. which component this, , how can utilize programmatically c# app (not web)? they're client-side, , use different sources location information. w3c api in firefox uses google location services (a json api) , bet google gears uses google database well, while loki uses skyhook wireless service. , different browsers implement w3c api can use different location services. mobile safari uses skyhook, or gps info device itself. you @ of these providers accessing location through desktop app. google location services appears particularly simple web api, think can programmatic access skyhook. since you're writing in c#, might windows 7 location platform, provides easy-to-use os-level framework abstracts away different providers. (sorry typos , lack of links; answer posted tablet.)

int[] a=new int[4]; i think when array created ..there constructor calling (assigning elements default values) if correct..where constructor.. no, there no such thing. primitive array elements initialized default primitive value ( 0 int ). object array elements initialized null . you can use java.util.arrays.fill(array, defaultelementvalue) fill array after create it. to quote jls an array created array creation expression (§15.10) or array initializer (§10.6). if use initializer, values assigned. int[] ar = new int[] {1,2,3} if using array creation expression (as in example), ( jls ): each class variable, instance variable, or array component initialized default value when created

i have 2 functions f , g , trying return f(g(x)) not know value of x , not sure how go this. a more concrete example: if have functions f = x + 1 , g = x * 2 , trying return f(g(x)) should function equal (x*2) + 1 it looks have right, f(g(x)) should work fine. i'm not sure why have return keyword there (it's not keyword in ocaml). here correct version, let compose f g x = f (g x) the type definition is, val compose : ('b -> 'c) -> ('a -> 'b) -> 'a -> 'c = <fun> each, 'a,'b,'c abstract types; don't care are, need consistent in definition (so, domain of g must in range of f ). let x_plus_x_plus_1 = compose (fun x -> x + 1) (fun x -> x * 2)

i got populate facttable 12 lookups dimension table sk's, of 6 different dim tables , rest 6 lookup same dimtable (type ii) doing lookup same natural key. ex: primeobjectid => lookup dimobject.objectid => objectsk and got other columns same otherobjectid1 => lookup dimobject.objectid => objectsk otherobjectid2 => lookup dimobject.objectid => objectsk otherobjectid3 => lookup dimobject.objectid => objectsk otherobjectid4 => lookup dimobject.objectid => objectsk otherobjectid5 => lookup dimobject.objectid => objectsk for such multiple lookup how should go in ssis package. for using lookup / unionall foreach lookup. there better way this. i assume doing lookup, errors redirected derived column set default values failed lookups, followed union each of lookup/derived column values. pattern common , use in stages debug. however, since union partially blocking component (ie union creates new buffer when executes, pass...

i want food class able test whenever equal instance of food . later use against list, , want use list.contains() method. should implement iequatable<food> or override object.equals() ? msdn: this method determines equality using default equality comparer, defined object's implementation of iequatable.equals method t (the type of values in list). so next question is: functions/classes of .net framework make use of object.equals() ? should use in first place? the main reason performance. when generics introduced in .net 2.0 able add bunch of neat classes such list<t> , dictionary<k,v> , hashset<t> , etc. these structures make heavy use of gethashcode , equals . value types required boxing. iequatable<t> lets structure implement typed equals method no boxing required. better performance when using value types generic collections. reference types don't benefit iequatable<t> implementation let avoid cast sy...

do know if possible launch or attach uiautomation tool process on actual ios device using instruments command line interface ? i know there command line interface instruments far haven't been able connect device. there bug in command line instruments interface. it's documented here: http://openradar.appspot.com/9150033 i filed bug through job, , closed dupe of one. when fixed, should work following: http://developer.apple.com/library/mac/#documentation/darwin/reference/manpages/man1/instruments.1.html the workarounds hacky, instruments product lacks osascript extensions well. i'm going investigating hacks, while waiting fix come through.

does have advice how read comma separated data file matlab? simple solutions (like dlmread, fscanf) not seem work, there multiple (10) lines of header information. closest got solution is: c=textscan(datafile) g=cell2mat(c{1,1}(34:endoffile)}) //34 line data starts v=str2num(g) the problem here data instance looks this: ;1.0345,937,18,763 ;1.0355,947,4,652 etc. when converting matrix strings in cell have of same size, otherwise error using 'vertcat' given. if no other option, delete header in lets notepad, many many files tedious job. dlmread accepts starting row/column parameters, or alternatively range parameter. if data starts on line 10, try v = dlmread(datafile, '', 9, 0); if prefer textscan , can specify number of headerlines skip: v = textscan(datafile, ..., 'headerlines', 10, ...); scan down "user configurable options" on documentation page more details.

how can check table have index or not ? if have how find index particular column table? regards, kumar in sql server management studio can navigate down tree table you're interested in , open indexes node. double clicking index in node open properties dialog show columns included in index. if use t-sql, might help: select sys.tables.name, sys.indexes.name, sys.columns.name sys.indexes inner join sys.tables on sys.tables.object_id = sys.indexes.object_id inner join sys.index_columns on sys.index_columns.index_id = sys.indexes.index_id , sys.index_columns.object_id = sys.tables.object_id inner join sys.columns on sys.columns.column_id = sys.index_columns.column_id , sys.columns.object_id = sys.tables.object_id sys.tables.name = 'table name here' order sys.tables.name, sys.indexes.name, sys.columns.name

i've got table (col1, col2, ...) index on (col1, col2, ...). table has got millions of rows in it, , want run query: select col1, count(col2) col1 not in (<couple of exclusions>) group col1 unfortunately, resulting in full table scan of table, takes upwards of minute. there way of getting oracle use index on columns return results faster? edit: more specifically, i'm running following query: select owner, count(object_name) all_objects group owner and there index on sys.obj$ ( sys.i_obj2 ) indexes owner# , name columns; believe should able use index in query, rather full table scan of sys.obj$ i have had chance play around this, , previous comments regarding not in red herring in case. key thing presence of nulls, or rather whether indexed columns have not null constraints enforced. this going depend on version of database you're using, because optimizer gets smarter each release. i'm using 11gr1 , optimizer used index in cases exc...

i have developed own snmp service, , want plot graph of oid provided. so, have created graph in cacti. -) showing device up. -) creating rrd file. (rrdtool says ok). -) showing graph, it's empty. but when check it, say rrdtool fetch <rrd file> average it shows me nan values. monitored oid has value 47 , have set min=0 , max=100. i using cacti appliance rpath: http://www.rpath.org/ui/#/appliances?id=http://www.rpath.org/api/products/cacti-appliance still, can't show value on graph.. where problem? can please tell me? first of all, use cacti's "rebuild poller cache" function under utilities menu. if didn't work ,check if rrd file updating new data. use command: rrdtool last [filename.rrd] output last time (in unix timestamp) new value has been inserted rra file can compare current time date +%s output. if it's not updating data should change cacti log level debug via settings page on cacti's web ui , appropriate m...

i have built application revolves around uitableview, core data , xml. app complete want add main menu before accessing tableview. main menu allow navigate table , other functions. easiest way go doing this? i'm confused how change inital file loaded. one suggestion add navigation controller , new view serve 'main' view , show menu. in response 'menu' choices push existing table view or other views might want show.

i'm facing weird problem in sliverlight 4 + ria services, or maybe it's not weird , i'm newbie anyway hope here can help, problem following i've created function on server side inside domain service function simple , has line in adds server current date , time database (it's hr application , employees should sign in , out thrue each it's own pc ) emp.timeout = system.datetime.now (c# syntax) the weird part users adds 3 hours current time(exp if signs out @ 5 shows 8) , others works perfectly. the server , stations in company have same time settings , same time zone, , anyway function on server side should no related users time. any ideas why happening? i've been trying find out why days no luck. you need use utc values ... everwhere there serialization involved ... whether db or client. convert local time when appropriate display/human readin (and in case of input)

i have dnn module renders user control (view.ascx) all ok ( logged in ) , dnn settings menu. however when add control , load so: string url = globals.navigateurl(portalsettings.activetab.tabid, "view_details", "mid=" + moduleid.tostring()); response.redirect(url); i lose settings link when new control loads. any ideas? there property somewhere turn on settings loaded user control? when have "mid" in querystring, you're going using module isolation (i.e. module control show in edit skin's contentpane , module on page). when in module isolation, action menu doesn't include settings. fact of dnn. you have couple of options. first, choose navigation method (see michael washington's old (but still good) module navigation options dotnetnuke® module article). second, put own link settings on control. may able implement iactionable , add action menu (i'm not sure if work), or can add sort of button or navigati...

i have code @column(updatable=false) @enumerated(enumtype.string) private examtype examtype; however, can still change value when update via merge. why? ok. first, if want examtype column included in sql update statements, shouldn't mark updatable=false . being said, appears updatable=false ignored when not used in combination insertable=false that's bug in eclipselink ( bug 243301 ), that's not jpa says. set true or remove it. secondly, following entity: @entity public class myentity { @id @generatedvalue private long id; @column(updatable = true) @enumerated(enumtype.string) private examtype examtype; ... } the following test method runs fine eclipselink: @test public void testupdateofenum() { myentity e = new myentity(); e.setexamtype(examtype.a); em.persist(e); em.flush(); assertnotnull(e.getid()); assertequals(examtype.a, e.getexamtype()); e.setexamtype(examtype.b); em.merge(...
