i have wpf mvvm application i'd refactor use mvvmcross support wpf , mono android implementations. our application's views consists of: a toolbar visible a navigation bar region a main view region a popup window region each of these regions usercontrol on main application window , uiservice swaps out views in each region. in case of pop-up window, usercontrol on main window that's visibility changes on show or hide calls uiservice. uiservice accepts context parameter allows state information passed view model shown. the main views typically composite of several child views. in these cases, main view model creates child view models exposed properties. main view sets these properties data context of child views. i think mvvmcross support style composite views, couldn't find example of such. there relevant mvvmcross examples? recommended approach implementing in mvvmcross? i think mvvmcross support style composite views, couldn...

i can't figure out why m1 apparently memoized while m2 not in following: m1 = ((filter odd [1..]) !!) m2 n = ((filter odd [1..]) !! n) m1 10000000 takes 1.5 seconds on first call, , fraction of on subsequent calls (presumably caches list), whereas m2 10000000 takes same amount of time (rebuilding list each call). idea what's going on? there rules of thumb if , when ghc memoize function? thanks. ghc not memoize functions. it does, however, compute given expression in code @ once per time surrounding lambda-expression entered, or @ once ever if @ top level. determining lambda-expressions can little tricky when use syntactic sugar in example, let's convert these equivalent desugared syntax: m1' = (!!) (filter odd [1..]) -- nb: see below! m2' = \n -> (!!) (filter odd [1..]) n (note: haskell 98 report describes left operator section (a %) equivalent \b -> (%) b , ghc desugars (%) a . these technically different becaus...

i have safari extension popover needs communicate global page. content-script using safari.self.tab.dispatchmessage(name,data); to accomplish that. popover didn't find way that. know can access methods in global page directly safari.extension.globalpage.contentwindow but goal reuse code fragments used in content-scripts. same chrome version of plugin. is there code little clever proxy emulates safari.self.tab.dispatchmessage(name,data); from popover? to honest it's easier have different code in popover , injected scripts. if want, this: function dispatchmessage(name, message) { if (safari.self.tab) { safari.self.tab.dispatchmessage(name, message); } else if (safari.extension.globalpage.contentwindow) { safari.extension.globalpage.contentwindow.handlemessage({name: name, message: message}); } } then use dispatchmessage('foo', 'bar') in both popover , injected scripts. it's bit hacky though, because...

in tone generator example ios: http://www.cocoawithlove.com/2010/10/ios-tone-generator-introduction-to.html i trying convert short array float32 in ios. float32 *buffer = (float32 *)iodata->mbuffers[channel].mdata; short* outputshortbuffer = static_cast<short*>(outputbuffer); (uint32 frame = 0, j=0; frame < innumberframes; frame++, j=j+2) { buffer[frame] = outputshortbuffer[frame]; } for reasons, hearing added noise when played speaker. think there problem conversion short float32? yes, there is. consider value-range floating point samples -1.0 <= xn <= 1.0 , signed short -32767 <= xn <= +32767 . merely casting result in clipping on virtually samples. so taking account: float32 *buffer = (float32 *)iodata->mbuffers[channel].mdata; short* outputshortbuffer = static_cast<short*>(outputbuffer); (uint32 frame = 0, j=0; frame < innumberframes; frame++, j=j+2)...

i programming mulithreaded client/server between processes program uses message queue's. server handle message's send clients, , later should give work threads continue handling it's processes. every client have different message queue. after making connection of 1st client , sending thread handle using pthread_join doesnt allow me to receive new connections on main thread,cause it's blocked how can fix it. receiving new messages in main thread ( or other solution if possible) sending threads handle client message's , after. getting receive new message very simple, make threads create detached main thread - means don't need "pthread_join" them anymore. main thread getting new connections , new request existing connections in loop, if it's new connection start new thread , if it's request existing connection it's add request thread's queue (using lock on it's mutex ofcourse).

this code segment have written in c#. mobile , name columns in table. problem there wrong format of query. syntax correct if want connect 2 queries in c # using or? sqldataadapter da = new sqldataadapter("select * [contact management] mobile='"+convert.toint32(txtsearch.text)+"' or name='"+txtsearch.text+"'",con); no, syntax not correct. it's vulnerable sql injection attacks. need build this: sqlcommand cmd = new sqlcommand("select * [contact management] mobile= @search or name= @search") sqldataadapter = new sqldataadapter(cmd); cmd.parameters.add("@search", sqldbtype.nvarchar, 50).value = txtsearch.text; you write query way: select * [contact management] @search in (mobile, name)
