i have 1 numericupdown1 control if select 5 in numeric down control.the calling value this: numericupdown1.value that return value 5 integer instead of getting 5. want value in time format if select 5 .that should return 00:05:00 .. how can convert numeric down value times.. in data base want store value data type time(7).i tryed this: dim value timespan = convert.todecimal(numericupdown1.value) but getting error you using timespan wrongly, better rely on date : dim value date = new date(now.year, now.month, now.day, 0, numericupdown1.value, 0) you can convert variable string format want doing: dim valueasstring string = value.tostring("hh:mm:ss") this right way use timespan : dim value timespan = new timespan(0, numericupdown1.value, 0) but recommend date alternative above. use timespan measuring intervals (between date type variables) , better store date/time-related information date , easier deal with.

scenario : sensitive information exchanged (1) client server , (2) server client . problem : data exchanged not encrypted, sniffing easy (it's theoretically possible, right?) solution : encrypt data transmitted in either direction (server-to-client , client-to-server). implementation : (1) client server - generate certificate, install private key on server , configure tomcat work on https (many tutorials online). (2) server client - private key goes (or generated by) clients, seems tutorials emphasize that every client should have own certificate sake of authentication. question: if authenticating users through database username/password (hashed salt) combo, still need encrypt server-to-client data transmissions reduce chance of sniffing, can generate 1 private key clients? there other ways of achieving need tomcat/spring? it seems you're mixing up: regular https includes encryption in both directions, , private key + certificate on server side....
