Issue: Change in behavior from Office 2007 RTM to SP2 when Sheet.Unprotect is called
Let’s say you have a password protected Excel workbook, and you are calling following function through VBA in it:
Sheet.Unprotect Password:=""
If you run this macro in Office 2007 RTM or SP1 version, it will result in a VBA Error; provided the actual password is not an empty string. However, in SP2 it will result in a password input dialog box.
This change of behavior is the result of a design change for SP2 release.
In case you have a code/logic which depends on the handling of VBA Error received in Office 2007 RTM/SP1 for wrong password specified for the above call, you can get the same behavior in SP2 release by passing a dummy password instead of an empty string.
For example:
Sheet.Unprotect Password:="dummy"
If the specified string is the correct password then the Sheet will be unprotected without any error or showing the Password input dialog box.
