i have an application where it is password protected and connects to an MS Access DBase where there is a table in  it called "Users". Inside that table are the following fields.

Forename   Surname   Username    Password

each user can type in their username and password and logs into the program OK.

i would like to know how i can setup each persons account PASSWORD to expire in a certain amount of days and show on my form how many days are left before they have to change their password.

put a datefield called let's say "LastPwdChange".

Whenever you log-in, check this date against the current date using DateDiff ("d", Now(), rs.fields("LastPwdChange"))

if the result of Datediff is > number of days for expiration then prompt for change, otherwise show the result of datediff

const DAYS_TILL_PASSWORD_EXPIRES = 14  '' 2 weeks for example

public sub login()

   Dim conn as new ADODB.Connection
   Dim rs as new ADODB.Recordset
   Dim strSQL as string
   Dim daysSinceChange as integer

   conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
              "Persist Security Info = False;" & _
              "Data Source=<your access db>"
   rs.open strSQL, conn, adOpenForwardOnly, adLockOptimistic

   if rs.EOF then
       msgbox "Incorrect User Name or Password"
   else
       daysSinceChange = DateDiff("d", Now(), rs.fields("LastPwdChange"))
       if daysSinceChange > DAYS_TILL_PASSWORD_EXPIRES then
            msgbox "you need to change your password"
            '' maybe open the form for doing so here
       else
            msgbox "you need to change your password in " & (DAYS_TILL_PASSWORD_EXPIRES - daysSinceChange)  
       end if        
   end if

   rs.close
   set rs = nothing
   conn.close
   set conn = nothing
     
end sub

oops, put rs.movefirst before the line "daysSinceChange = DateDiff(...)"

also probably want to pass the username and password to the login sub:
ie.
sub login(uName as string, pass as string)

'' also, strSQL should look something like
strSQL = "Select * from tblUsers where userName = '" & uName & "' and Password = '" & pass & "'"

end sub
