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.

Incremental update of docs in solr -

-

i have table called emp id , name fields , has 2 records. have formed xml doc 

<add>   <doc>     <field name="id">1</field>     <field name="name">name1</field>   </doc>   <doc>     <field name="id">2</field>     <field name="name">name2</field>   </doc> </add>

i have indexed above xml file solr first time. when 3rd record gets created in table, should go xml file has third record i.e 

<add>   <doc>     <field name="id">3</field>     <field name="name">name3</field>   </doc> </add>

and index xml file separately?

or should add new 3rd record original xml file i.e 

<add>   <doc>     <field name="id">1</field>     <field name="name">name1</field>   </doc>   <doc>     <field name="id">2</field>     <field name="name">name2</field>   </doc>   <doc>     <field name="id">3</field>     <field name="name">name3</field>   </doc> </add>

and index newly created xml file again? here when there millions of record generating xml file take time , indexing docs take time.

so, how need handle incremental indexing/updation scenario?

creating new xml file contains delta (i.e. new or changed rows) solves problem, , correct more efficient doing full export/import.

if want circumvent creating xml file, should dataimporthandler, lets import data (for instance) jdbc source. it's included contrib solr.

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.
