Hi. I've developed a workbook which i pretend to sell. Its a very complex workbook which has more than 700 worksheets and a lot of work invested. Has more than 100 macros across and i manage to establish a trial period based on this code:
This code above creates a log file that the macro uses at the opening to check if the file has trial period or not. What i need now is a code similar that creates a log file with the machine ID so then when this workbook opens checks if the machine id matches the one in the log file and if so let it open. Case not closes it right away. The log file stays hidden somewhere in the hard drive with a name i create (instructed in the vba code like the code above).
Is this possible to do?
Code:
Option Explicit
Private Sub Workbook_Open()
Dim StartTime#, CurrentTime#
'*****************************************
'SET YOUR OWN TRIAL PERIOD BELOW
'Integers (1, 2, 3,...etc) = number of days use
'1/24 = 1Hr, 1/48 = 30Mins, 1/144 = 10Mins use
Const TrialPeriod# = 30 '< 30 days trial
'set your own obscure path and file-name
Const ObscurePath$ = "C:\"
Const ObscureFile$ = "TestFileLog.Log"
'*****************************************
If Dir(ObscurePath & ObscureFile) = Empty Then
StartTime = Format(Now, "#0.#########0")
Open ObscurePath & ObscureFile For Output As #1
Print #1, StartTime
Else
Open ObscurePath & ObscureFile For Input As #1
Input #1, StartTime
CurrentTime = Format(Now, "#0.#########0")
If CurrentTime < StartTime + TrialPeriod Then
Close #1
Exit Sub
Else
If [A1] <> "Expired" Then
MsgBox "Sorry, your trial period has expired - your data" & vbLf & _
"will now be extracted and saved for you..." & vbLf & _
"" & vbLf & _
"This workbook will then be made unusable."
