i created ui uibuilder. instead of using findxxxx () , love in statemachine : public class statemachine ... { private container c; private tabs t; initvars () { initall(); } .... private initall () { container c = findcontainer(); tabs t = findtabs(); ... } } and use them c.getyyy() . is possible? if yes, how? yes can that, not advisable. the danger of when have 2 components same name on different forms, may reference wrong component , may hard debug. if sure can deal above, can declare , initiate variables inside statemachine class outside of methods private global variable. public class statemachine ... { private container c = findcontainer(); private tabs t = findtabs(); initvars () { } .... }

i finding taking current date (only date) in datetime datatype. for made googling , made following code>> datetime dtcurrdate; dtcurrdate=datetime.parseexact(datetime.now.date.toshortdatestring(),"mm/dd/yyyy",null); this code giving me exception : string not recognized valid datetime. what mistake within it? please me. i believe aware of datetime.now.date property, give current date time set 00:00:00 . now why having problem in parsing: probably because of current culture, datetime.toshortdatestring() give (for en-us culture): displaying short date en-us culture: // 6/1/2009 (short date string) and later parsing with: "mm/dd/yyyy" need single digit m , d so code be: dtcurrdate=datetime.parseexact(datetime.now.date.toshortdatestring(),"m/d/yyyy",null); it better if can store result of toshortdatestring() in string , check kind of format get, , parse accordingly.
