i using asp.net 4.0 , mvc 2.0 web application. project requiremrnt have use server side control in application not possibl in noraml case. ideally want use adrotator control , datalist control. i saw few samples , references in codepleax mvc controllib howwver found less useful. can tell how utilize theese controls in asp.net application along mvc. note: please provide functionalities related adrotator , datalist controls not equivalent functionalities thanks in advace. mvc pages not use normal .net solution makes use of normal .net components impossible. a normal .net page use event driven solution call different methods service side mvc use actions , view completly different way handle things. also, mvc not use viewstate normal .net controlls require. found article discussing mixing of normal .net , mvc.

algorithm - Split 2-3 tree into less-than and greater-than given value X -

-

i need write function, receives key x , split 2-3 tree 2 2-3 trees. in first tree there nodes bigger x, , in second less. need make complexity o(logn). in advance idea.

edited thought finding key x in tree. , after split 2 sub-trees(bigger or lesser if exist) 2 trees, , after begin go , every time check sub-trees i've not checked yet , join 1 of trees. problem leaves must @ same level.

assuming have covered 2-3-4 trees in lecture already, here hint: see whether can apply same insertion algorithm 2-3 trees also. in particular, make insertions start in leaf, , restructure tree appropriately. when done, determine complexity of algorithm got.

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
