i'm designing application. found make more modularize, number of dll's getting increased. better design have more number of dll's? regards arundhaj this common tricky question. don't overly fragmented dlls, makes quite hard (imo) track , deploy. prefer limited number of more chunky dlls. in addition project/dll management, reduces amount of work "fusion" has when loading things. you should aim reusable components, don't go mad making them too granular - consider "system.windows.forms.dll", example; quite lot in there! vertically, obvious ones keep separate ui / repository / logic concerns; horizontally tend have 1 column of dlls per logical area - can still compartmentalize namespaces , don't have keep dll just 1 thing.

so i'm trying add number of days date, , i'm getting strange issue: var date = new date(); var newdate = date.getdate() + $('#ddldays option:selected').val(); date.setdate(newdate); so if today 09/29/2010, date 29. if user selects "5" ddldays, assume adding strings together, adding 295 days date. i under impression javascript assume integers? getdate() return string instead of integer? how can fix this? if want add selected value day of month (i.e. 29 + 5), need parse string value int: var newdate = date.getdate() + parseint( $('#ddldays option:selected').val(), 10); but if want new date, rather int, result, can this: date.setdate( date.getdate() + parseint( $('#ddldays option:selected').val(), 10);
