i have uiview , added in xib file. through connection inspector join properly. in viewdidload: method hiding , on button pressed showing it. here code far: .h file @property (nonatomic, retain) iboutlet uiview *subview; in viewdidload: method: _subview.hidden = yes; it hiding view properly, on button pressed not showing up. - (ibaction)customerinvoice:(id)sender { //self->_subview.hidden = no; _subview.hidden = no; } using both ways not showing up. please, me resolve it. sometime (or xcode) can make mistake during connecting iboutlets/ibaction if doesn't work can remove connection , again, should help. also apple recommendation use weak instead of strong/retain iboutlet property if haven't got reason should do: @property (nonatomic, weak) iboutlet uiview *subview;

i have not experience in objectivec (ios) development i've seen many codes curiosity , found people using goto statement ( jsonkit library , code games, etc), apple's source code known use ( you can see here ). as have learned in academic life, using goto bad development pratice , must avoid, why "commom" pratice in ios development, there special reason?? it programming style use break , continue , , return statements instead of goto statement whenever possible. however, because break statement exits 1 level of loop, might have use goto statement exit nested loop. *source - microsoft one more example blog

i want row in layout radiobutton, edit text, textview surrounded radiogroup. radiogroup does't seem work way. i'm generating layout code not xml, show how like: <scrollview> <linearlayout> <radiogroup> <relativelayout> <radiobutton> <edittext> <textview> </relativelayout> <relativelayout> <radiobutton> <edittext> <textview> </relativelayout> </radiogroup> </linearlayout> </scrollview> i can select radiobuttons, group not working. wrong, or how solve problem? you can't have relativelayouts in radiogroup. view rendered expected, radio buttons won't function (they lose grouping). if need edittext inside each button, you'll have code radio button functionality yourself. however, if need different text styles inside radio bu...

between command not working correctly geo coordinates select * table_name loc_lng between $ln2 , $ln1 , loc_lat between $la2 , $la1 the code works fine when $ln2 smaller $ln1 , $la2 smaller $la1, dosent work when values $ln1 greater $ln2 , $la1 greater $la2. ln , la geo coordinates 1 bigger other. that's expected. need additional logic define minlatitude , maxlatitude , minlongitude , maxlongitude before pass values query. then query can be select * table_name loc_lng between $minlongitude , $maxlongitude , loc_lat between $minlatitude , $maxlatitude

as per how optimistic locking in hibernate , need enable optimistic locking version element or version annotation in hibernate. clear till here. i not sure purpose of lock mode optimistic ? in kind of scenario, developer should use ? to understand why want optimistic locking, first need understand no locking , pessimistic locking mean. i'm no hibernate expert, i'll tell without focus on hibernate. when 2 process/users update same object 1 updates last win. need find way prevent this. 1 way pessimistic locking. here, put lock on object @ moment load database "select update". until transaction commited or rolled back, nobody else can "select update" object. problem is: when load entity via hibernate, specify if want load read-only purpose or if want modify object. so here comes optimistic locking. concept assumes optimistically go ok in cases. when 2 processes/users update same object, second 1 not win, exception on commit.

i'm trying read , write hbase through rest api, have running on machine @ port 8085 (can see @ xxxxx:8085/rest.jsp) i've made script test , gives me 405 (i think it's "method not allowed" i'm not sure): #!/usr/bin/env python starbase import connection socket import gethostname hostname = gethostname() print "hostname: %r" % hostname con = connection(host=hostname, port=8085) print con.tables() i think have problem prerequisites i'm not sure, perhaps more experience can help. are there nicer solutions connect hbase , python? thanks. starbase works stargate http://wiki.apache.org/hadoop/hbase/stargate . stargate runs on port 8000 default. if have stargate running, should able see list of tables accessing xxxxx:8000 (8085 in case). if don't see that, you're running old , deprecated version of rest api. you try apache thrift framework http://thrift.apache.org or happybase (which based on apache thrift fr...

we using google compute engine instance generate convert datastore tables large downloadable csv files. want instance log errors app engine front end instance calling: /api/log but want sure call came google compute engine instance has authority write log. how can check api call came google compute engine instance? it depends on how secure want be. simplest solution include parameter in post request backend , front-end instances recognize - random sequence of characters trick. next level use secret key encrypt contents of request - there many implementations depending on language use. this approach more flexible too, if decide, example, move backend app engine compute engine.
