Folder Locking with vbscript

Question

I am stuck in the following script,Please Help

 ' Discover Current Drive Path
  curDrv = objFSO.GetParentFolderName(WScript.ScriptFullName) 'Drive Path
  ulpath = curdrv & "\Locker"
  propath = curdrv & "\Control_Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
  passFile = curdrv & "\pass.txt"
  If objFSO.FolderExists (propath) Then call Unlock

  If Not objFSO.FolderExists (ulpath) Then
  objFSO.CreateFolder (ulpath) 
  MsgBox "Folder Created Successfully" , vbInformation, "Process Success"  & WScript.Quit
  end if
  If objFSO.FolderExists (ulpath) Then call Lock
  WScript.Quit

  Sub PassCreate
  PSCR = InputBox ("Type a password to lock folder.                          Do Not use blank password for your safety.")
  IF PSCR="" then MsgBox "Password cannot be blank" , vbCritical, "Faulty"  
  IF PSCR="" & objFSO.FileExists(passFile) then
  objFSO.DeleteFile(passFile)
  end if
  IF PSCR="" then call PassCreate 
  Set objFile = objFSO.CreateTextFile(passFile,True)
  objFile.Write PSCR & vbCrLf
  objFile.Close
  End Sub

  Sub Unlock
  PSW = InputBox ("Please Enter your 10 digit Password.               Example : 9867123456")
  Set objFile = objFSO.OpenTextFile(passFile)
  Do Until objFile.AtEndOfStream
  strLine= objFile.ReadLine
  Loop
  objFile.Close
 If not PSW=strLine Then MsgBox "Wrong Password" , vbCritical, "Illegal Operation" & WScript.Quit
 objFSO.MoveFolder propath , ulpath
 Set FO = objFSO.GetFolder(ulpath)
FO.Attributes = FO.Attributes AND 0 
MsgBox "Folder Unlocked Successfully" , vbInformation, "Success Operation" & WScript.Quit
End Sub 

 Sub Lock
 Message = "Are you Sure you want" & vbCr & vbCr
 Message = Message & "to Lock the folder ?" & vbCr & vbCr
 X = MsgBox(Message, vbOKCancel, "Confirmation")
 If not objFSO.FileExists (passFile) then call PassCreate

 Select Case X

 Case vbOK
 objFSO.MoveFolder ulpath , propath
 Set objFolder = objFSO.GetFolder(propath)
 Set FL = objFSO.GetFolder(propath)
 FL.Attributes = FL.Attributes XOR -1
 MsgBox "Folder Locked Sucessfully." , vbInformation, "Process Success"

Case vbCancel
MsgBox "Nothing Done." , vbExclamation, "Process Aborted"
End Select

End Sub 

Under sub passcreate if the password is blank first time nothing is written to the pass.txt so no password created.I want to prevent accidental blank password creation.I do not know how to cancel script execution if cancel is selected on the both the inputbox.

Answer 1

Use exit sub just below the condition where you are checking if password is empty eg:

IF PSCR="" then
  MsgBox "Password cannot be blank" , vbCritical, "Faulty"  
  Exit Sub
End If

Answer 2

Why not ask for the password in a loop like this.

PSCR = ""
DO While PSCR = ""
    PSCR = InputBox ("Type a password to lock folder.                          Do Not use blank password for your safety.")
    IF PSCR="" then 
        MsgBox "Password cannot be blank" , vbCritical, "Faulty" 
    END IF 
Loop

That way the user would have to enter a password to continue running the script.

EDIT: This should do everything you want.

Sub TheScript
    password = GetPassword
    If password = "" Then Exit Sub
    MsgBox password
End Sub

Function GetPassword
    PSCR = ""
    DO While PSCR = ""
        PSCR = InputBox ("Type a password to lock folder. Do Not use blank password for your safety.")
        If IsEmpty(PSCR) Then 
            MsgBox "Cancel Pressed"
            Exit do            
        ElseIf PSCR = "" Then
            MsgBox "Password cannot be blank" , vbCritical, "Faulty"            
        End If
    Loop
    GetPassword = PSCR
End Function
