my address variable equal at address =C:\\prpgm\\prpgm\\program.accdb but its change every time and address doesnt work in file.copy what must ı write in parantesis that will be equal to address forc ever time
File.Copy(address,.....) should solve the problem, u have already assigned a string to address variable, why do you want to pass address as a string inside the quotes.
you have hard coded the path, it will not change, or make sure you have a specific logic from where you get the path. may be u can assign that path to address each time and it will work fine.
or if possible you can paste here all that you have done.
