-

i want calculate new date adding number of months specific date.

for example:

i have date "06/30/2012" (30th june 2012), , number of months "2" or "3" months.

now want function gets both values , returns date 2 months after specified date.

please show me how can achieved.

you can try putting code, has need date addition/subtraction 

date.prototype.add = function (sinterval, inum){       var dtemp = this;       if (!sinterval || inum == 0) return dtemp;       switch (sinterval.tolowercase()){         case "ms":           dtemp.setmilliseconds(dtemp.getmilliseconds() + inum);           break;         case "s":           dtemp.setseconds(dtemp.getseconds() + inum);           break;         case "mi":           dtemp.setminutes(dtemp.getminutes() + inum);           break;         case "h":           dtemp.sethours(dtemp.gethours() + inum);           break;         case "d":           dtemp.setdate(dtemp.getdate() + inum);           break;         case "mo":           dtemp.setmonth(dtemp.getmonth() + inum);           break;         case "y":           dtemp.setfullyear(dtemp.getfullyear() + inum);           break;       }       return dtemp;     }      //sample usage     var d = new date();     var d2 = d.add("d", 3); //+3days     var d3 = d.add("h", -3); //-3hours     var d4 = d.add("mo", 2); //+2 months

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

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...
