c# - Databindings.Add really slow -

-

i asked question yesterday , reference: keeping track of 40+ control values

i binding bunch of controls property class; however, slows down gui portion of application. example, following code:

        numericupdownphysicalais.databindings.add("value", configurationvalues, "physicalais");         numericupdowninternalais.databindings.add("value", configurationvalues, "interalais");         numericupdownphysicalaos.databindings.add("value", configurationvalues, "physicalaos");         numericupdowninternalaos.databindings.add("value", configurationvalues, "internalaos");         numericupdownsetpoints.databindings.add("value", configurationvalues, "setpoints");         numericupdownindexregisters.databindings.add("value", configurationvalues, "indexregisters");         numericupdownnetworkid.databindings.add("value", configurationvalues, "networkid");         numericupdownquiescentoperationstartupdelay.databindings.add("value", configurationvalues, "quiescentoperationstartupdelay");         numericupdownquiescenttelemetrytable.databindings.add("value", configurationvalues, "quiescenttelemetrytablescanrate");         numericupdownpercentquiescentthreshold.databindings.add("value", configurationvalues, "percentquiescentthreshold");         numericupdownpercentageofquiescentinterval.databindings.add("value", configurationvalues, "percentquiescentinterval");         numericupdownaodayweek.databindings.add("value", configurationvalues, "aodayweek");         numericupdownaodaymonth.databindings.add("value", configurationvalues, "aodaymonth");         numericupdownaomonthyear.databindings.add("value", configurationvalues, "aomonthyear");         numericupdownaoyear.databindings.add("value", configurationvalues, "aoyear");         numericupdowntimeday.databindings.add("value", configurationvalues, "timeday");         numericupdowndebugstatementnumbersetpoint.databindings.add("value", configurationvalues, "debugstatementnumbersetpoint");         numericupdowntelemetrycontrolsetpoint.databindings.add("value", configurationvalues, "telemetrycontrolsetpoint");         numericupdowncommunicationfaildi.databindings.add("value", configurationvalues, "communicationfaildi");         numericupdowncommunicationfailaddressao.databindings.add("value", configurationvalues, "communicationfailaddressao");         numericupdownaddressunreachableao.databindings.add("value", configurationvalues, "addressunreachableunitao");         numericupdownpowercountao.databindings.add("value", configurationvalues, "powercountao");         numericupdownresetcountao.databindings.add("value", configurationvalues, "resetcountao");         numericupdownrandomnumberao.databindings.add("value", configurationvalues, "randomnumberao");

it takes 30 seconds minute form show numeric up/down boxes. if comment code out, gui pops instantly. limitation of databindings.add method?

thanks

c# - Copy ObservableCollection to another ObservableCollection -

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...
