-

i creating website used accounting dept. track budget expenditures different projects.

i using sql server 2008 r2 database , asp.net c# mvc 3 website.

what boss has asked me every time user updates or creates project, need log change new table called mapping_log. should record whole mapping row being saved or created, , additionally user , datestamp. notes field mandatory, , note should saved mapping_log.

now when editing pa, notes field empty , below it, should have list of older notes organized date. have been looking maybe using nlog , log4net have not been able find tutorials situation mine. seems modules used error logging, although important not try @ moment.

i need direction... have advice or tutorials use learn how can implement process keep track of changes made data users of site.

thanks help/advice!

you can consider 2 new features sql server 2008 introduced: change tracking , change data capture.

you use , avoid custom mapping_log table.

but if need apply more complex -business- rule, perhaps better doing in application layer, rather purely in database.

regards.

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
