Prevent others from running my macros
 

Hi all,

Very often I have to send my Excel files (with macros) to others. Is there
any simple way of preventing third parties from running the macros in those
files? Thanks.

Prevent others from running my macros
 

The simple way would be to require a password to run the macro:

Public Sub MyMacro()
Const sPWORD As String = "drowssap"
Dim vResponse As Variant
Do
vResponse = Application.InputBox("Password: ", Type:=2)
If vResponse = False Then Exit Sub 'User Cancelled
Loop Until vResponse = sPWORD
'your code here
End Sub

Then protecting your code (Tools/Project Properties in the VBE).

However, that will not keep anyone with the gumption to find these
newsgroups from finding a way to see/run your macros:

A more secure way is to put your code in a separate add-in so that it's
never sent to the others.

Thanks a lot. A textbox asking for a password is a workable solution.
