hi good afternoon,

hi good afternoon,
               am creating one point of sale software in vb.net ,today only i realize that i need a backup for the database i have attached with this project,after change my project as executable file how can i or my clients can take the backup for that database please send me the coding ..i am creating project with vb.net2010 and ms access 2007 database...thank you

What coding? Just copy the files to another hard drive.

after make the project as exe file i need to take the auto backup for my database how can i write the coding for that

What you want is a tool or feature of the system that can backup the database by clicking a button?

feature of the system that can backup and restore the database by clicking a button please send me the coding

O.K. You can't just have one button to do the backup and restore at the same time. This doesn't make sense. So you need either 2 buttons, one to backup and one to restore or set a flag with a radiobutton or something else.
OK. this what I do: At the first use of my program I createall the databases and folders the program needs. So on first run I create the backup folder:

Case 14 'create the backupfolder on first run of the program
                My.Computer.FileSystem.CreateDirectory(mypath & "\" & constfoldername & "\" & "Backups") 'create workingfolder in th app directory
                InClass.Label7.Text = "Created Backup Folder"

When it comes to backing files up I first create a folder with todays date and then copy the files the user wants to back up into this folder:

Case 15 'create the backup files
                Dim st As String
                st = Now.ToString("D")

                If My.Computer.FileSystem.DirectoryExists(mypath & "\" & constfoldername & "\" & "Backups" & "\" & st) = False Then
                    My.Computer.FileSystem.CreateDirectory(mypath & "\" & constfoldername & "\" & "Backups" & "\" & st)
                End If

                If My.Computer.FileSystem.FileExists(mypath & "\" & constfoldername & "\" & "Globals" & "\" & "Forms.txt") Then
                    My.Computer.FileSystem.CopyFile(mypath & "\" & constfoldername & "\" & "Globals" & "\" & "Forms.txt", mypath & "\" & constfoldername & "\" & "Backups" & "\" & st & "\" & "Forms.txt", True)
                End If
