i'm having problem storyboard has beside navigation controller modal views separate them main "route" in app. when press button modal segue opens other view. the problem is: when go navigation controller , press button open modal view again, creates new instance of view controller without deleting old one. is possible clean memory when leaving modal view or something? i found solution: when finished separated modal view part, use [[self presentingviewcontroller] dismissviewcontrolleranimated:yes completion:nil]; , app goes last view controller, in case uinavigationcontroller. , this, deallocates old views.

i have osgi bundles provide services , require services . if have service implements interface , interface provides variety of methods can have reference these methods in service registry or somewhere other bundles can aware of these methods. if service implements interface method on interface implemented service, definition in java. other bundle knows service (and interface) aware of these methods. if want advertise bundles not know interface, register properties. however, definition accessing methods require reflection. in general not way go in java, nicer stay type safe , use interface anchor.

i updates on lifted entities using slick. code updates firstname of contact object: def updatecontact(id: int, firstname: option[string]): unit = { val q1 = { c <- contacts if c.id id } yield c.firstname // update value same or new value q1.update(firstname.getorelse(q1.list().head)) } the option here useful updating value in case (although nicer if update happened if there new value). what looking way query object id, updates in memory using getorelse , update on whole object. else have run above each field of object works know, feels dirty hack. instead of q1.update(firstname.getorelse(q1.list().head)) can write firstname.foreach{ fn => q1.update(fn) } shorter, simpler, 1 instead of 2 queries :). using foreach on option stops looking weird when think of collection 1 or 0 elements. regarding idea fetch whole object, modify , save back, can this: def updatecontact(id: int, firstname: option[string], lastname:option[string], ...): unit ...

i need validate few attributes in model when present in params while updating or creating object. validates :attribute_a,format: {with: /some_regex/}, :if => lambda{ |object| object.attribute_a.present? } like attribute_a there multiple attributes may not present while being created or updated .instead of writing validates statement each of them,is there way in can check presence of multiple attributes , validate every 1 common validation such inclusion_in or format:{with:/some_regex/ } . i wanted following code wrong. validates :attribute_a,attribute_b,attribute_c,attribute_d,:format => {:with => /some_regex/}, :if => lambda{ |object| object.attribute_name.present? } you can use validates_format_of : validates_format_of :attr_a, :attr_b, with: /someregexp/, allow_blank: true the allow blank option means regexp doesn't have match if attribute not present.

you can create dynamic queries in c# if add more restrictions current query. var list = new list<item>(); var q = list.asqueryable(); q = q.where(x => x.size == 3); q = q.where(x => x.color == "blue"); in case, every new predicate added performing , operation previous. previous result equivalent to: q = list.where(x => x.size == 3 && x.color == "blue"); is possible achieve same result or instead of and? q = list.where(x => x.size == 3 || x.color == "blue"); the idea have variable number of expressions joined or operator. expected result need written in how similar following pseudo code: var conditions = new list<func<item, bool>>(); and later iterate conditions build like: foreach(var condition in conditions) finalexpression += finalexpression || condition; thanks raphaël althaus gave following link: http://www.albahari.com/nutshell/predicatebuilder.aspx predicate builder soluti...

i have asp.net application updating use jquery ajax calls web service return json rather having gridview perform rendering. the contents of grid controlled various radio buttons. presently application set perform postback when radio button changed, store selected value in session , rebind data grid. the values held in session page 'remember' criteria used , reapply them if user navigates separate page in application , navigates grid. i have amended use knockout js handle data binding , presentation. viewmodel calls asmx web service returns json needs displayed. far good. i stuck set session variables - when jquery ajax call made web service web service has no current session can't store variables here. i don't think jquery / javascript can save session variables i'm bit stuck. anyone have ideas? many thanks chris

i need 2 regex regular expressions. 1 find second block of numbers , 1 find third block of numbers. data this: 8782910291827182 04 1988 081 one code find 04 , other find 1988 . have expression find first 16 numbers , last 3 numbers, stuck in finding 2 numbers of second , third section. use field-splitting instead based on corpus, seems 1 should able rely on existence of 4 fields separated tabs or other whitespace. splitting fields easier building , testing regex, i'd recommend skipping regex unless there edge cases not included in examples. consider following ruby examples: # split string fields. string = '8782910291827182 04 1988 081' fields = string.split /\s+/ #=> ["8782910291827182", "04", "1988", "081"] # access members of field array. fields.first #=> "8782910291827182" fields[1] #=> "04" fields[2] #=> "1988" # unpack array elements variables. fi...

i work in both php , java projects, ubuntu machine has both apache2 server , apache tomcat server installed. problem is, when run java application eclipse, url is, localhost:8080/myjavaapp and when enter credentials , log in url should be localhost:8080/myjavaapp/homepage.jsp but browser how taking localhost/myjavaapp/homepage.jsp hence error. when edit url adding 8080 port number, works fine. annoying edit url adding 8080 every time. appreciated. thanks. change default port tomcat else, example 8181 current versions of web browsers recognize port 8080 80, that's why it's forward 80 or cut port option url. to change tomcat port open server config file server.xml search "8080", current port in use, , replace else (make sure new port not in use) , save , restart tomcat.
