XL97: Protect Method Password Is Not Applied to Worksheet (161221)

CAUSE

This problem occurs when both of the following conditions are true:

You use a second ActiveSheet.Protect command that specifies a password in the macro. -and-
You set all the arguments (Contents, Scenarios, and DrawingObjects) for the second ActiveSheet.Protect command to True.

NOTE: Microsoft Excel may not apply password protection depending on the values of the arguments for the Protection statement. In some cases, Microsoft Excel applies worksheet protection but does not apply a password even if you specify a password in the macro.

WORKAROUND

To work around this problem, use either of the following methods.

Method 1

Use the ActiveSheet.Protect command only once and supply all the arguments, including the password. For example, use the following macro:

   Sub ProtectSheet()

       ActiveSheet.Protect password:="pw", Contents:=True, _
           Scenarios:=False, DrawingObjects:=True, UserInterfaceOnly:=True

   End Sub

Method 2

Set one of the Protect method arguments to False. To do this, use either of the following methods:

If the macro is recorded, clear one of the following check boxes: Contents, Objects or Scenarios. -or-

If the macro is manually typed, use the following syntax:

       Sub ProtectSheet()

          ActiveSheet.Protect password:="pw", Contents:=True, _
              Scenarios:=False, DrawingObjects:=True, _
              UserInterfaceOnly:=True

      End Sub

to set either Contents, Scenarios, or DrawingObjects to False.

MORE INFORMATION

Microsoft Excel 97 allows you to add an additional layer of protection by applying password protection to a previously protected sheet. You can add this protection programmatically.

In earlier versions of Microsoft Excel, using the ActiveSheet.Protect command more than once has no effect. In Microsoft Excel 97, using the command a second time with a password applies password-level security to a previously protected sheet as long as the arguments for Contents, Scenarios, and DrawingObjects are not all set to True. When all the arguments are set to True, Microsoft Excel protects the active sheet but does not apply password-level protection. The value of the UserInterfaceOnly argument has no effect on this behavior.

The following sample code demonstrates the problem:

     Sub Test()

       ActiveSheet.Protect
       ActiveSheet.Protect password:="pw", contents:=True, _
           Scenarios:=True, DrawingObjects:=True, UserInterfaceOnly:=False

   End Sub
