the app have under development utilizing lot of plist that's taking lot of space. considering zipping plist files. @ runtime, app unzip them nsdata , deserialize them nsdictionary using nspropertylistserialization eventual use. is there risky approach? or useless if property list output encoding set binary. if getting point you're considering zipping property lists save on space, think it's time move different format. property lists storing few defaults or settings, they're not replacement database. my recommendation @ moving data core data database. if trying embed large digital files elements in property list, @ storing separate resources in application bundle or in application's /documents directory. core data allow lazy-load items need them, saving on load times , memory, , sqlite base provide fast read / write times.

i new databases. if make primary key 2 columns, userid , dayofweek . how can search primary key? (dayofweek int 1 = monday, 2 = tuesday, etc.) would use: select * userid = 1 , dayofweek = 4 would scan entire database or use information provided primary key? there more appropriate query use? a primary key index internally other index, except you're explicitly saying this key uniquely identifies record. it's index "must unique" constraint imposed on it. whether db uses composite primary key depends on how specify key fields in query. given pk(userid, dayofweek), then select * mytable (userid = 1); select * mytable (userid = 1) , (dayofweek = 4); would both use primary key index, because you've used fields in order they're specified within key. however, select * mytable (dayofweek = 4) will not, because userid not specified, , userid comes before dayofweek in key definition.

now have project sign language recognition , accomplish project need program image processing,detection,tracking,recognition phases....etc i know best use: vc++ opencv or vc# aforge.net ? thanks in advance :) the short answer is, know. things consider: operational: know? know c++ , c# equally well? feel comfortable in? based on windows? application run on windows? engineering: have work in real time? how important it works in real time? how many man hours have project? scientific: methods plan use? sure these methods work or there trial , error required? as can see, there no "best" in type of things tradeoff, balance between many competing needs.

what difference between -[uiviewcontroller viewwillappear:] , -[uiviewcontroller viewdidappear:] ? in general, do: 1) viewdidload - whenever i'm adding controls view should appear view, right away, put in viewdidload method. method called whenever view loaded memory. example, if view form 3 labels, add labels here; view never exist without forms. 2) viewwillappear : use viewwillappear update data on form. so, example above, use load data domain form. creation of uiviews expensive, , should avoid as possible doing on viewwillappear method, becuase when gets called, means iphone ready show uiview user, , heavy here impact performance in visible manner (like animations being delayed, etc). 3) viewdidappear : finally, use viewdidappear start off new threads things take long time execute, example doing webservice call data form above.the thing because view exists , being displayed user, can show nice "waiting" message user while data.

how .net decides order of items when iterating through collections ? for example: list<string> mylist = new list<string>(); mylist.add("a"); mylist.add("b"); mylist.add("c"); foreach (string item in mylist) { // what's order of items? -> b -> c ? } i need order (accessing collection members): for (int = 1; < mylist.count; i++) { string item = mylist[i - 1]; // order need } can safely use foreach list ? other types of collections? .net doesn't decide - class implementing ienumerable decides how being done. list index 0 last one. dictionary depends on hash value of key think. list indexes 0 based, can this: for (int = 0; < mylist.count; i++) { string item = mylist[i]; // order need } and same result foreach . if want explicit stick loop. nothing wrong that.

i using open source library npgsql http://pgfoundry.org/projects/npgsql/ manipulate third party data on postgres database. database encoded sql_ascii. if run query using standard c# string insert cities(cityname) values("köln") the value shows in database looks more like: пїЅпїЅпїЅпїЅпїЅпїЅпїЅпїЅпїЅпїЅ e.g. scrambled. i've spent many hours trying use different string encodings etc no success sql_ascii means turn off encoding functionality in database. it's make sure clients use same encoding. believe npgsql use utf8, , cannot changed. so there no "the value shows in database" - depending on encoding client talks database in. the best way fix set actual encoding in database, , set useful - such utf8 or latin1.
