Hi David,
You can't sign a single .BAS file. What you can do is signing VBA projects
associated with Word, Excel, and PowerPoint documents, templates, and
add-ins. For Outlook, you can sign the VBA project that is associated with
the installation of Outlook on a particular computer, or if user profiles
are in use, for a particular user on that computer.
You should do this only after your solution has been tested and is ready
for deployment, because any time code in a signed VBA project is modified
in any way, its digital signature is removed. However, modifying the
contents of the document other than the VBA code won't invalidate the
signature on a VBA project contained within the document. This is because
only the VBA project is signed, not the entire document. If you want to
prevent users of your solution from accidentally modifying your VBA code
and invalidating your signature, lock the VBA project before signing it.
To lock a VBA project:
1. Open the Visual Basic Editor.
2. In the Project Explorer, right-click the project you want to protect,
and then click ProjectName Properties on the shortcut menu.
3. On the Protection tab, select the Lock project for viewing check box,
enter and confirm the password, and then click OK.
To digitally sign a VBA project
1. Open the document or template that contains the VBA project you want to
sign. For Outlook, open Outlook on the computer that contains the VBA
project you want to sign. If user profiles are in use, log on as the user
whose Outlook VBA project you want to sign.
2. Open the Visual Basic Editor.
3. In the Project Explorer, select the project you want to sign.
4. On the Tools menu, click Digital Signatures. Do one of the following:
* If you haven't previously selected a digital certificate, or want to use
another one, click Choose, select the certificate, and click OK twice.
* Click OK to use the current certificate.
Note: If a VBA project has been signed previously, clicking Choose and
selecting a new digital certificate replaces the previous signature. To
remove a signature from a previously signed project, click Remove.
If you have any further questions regarding this issue, please feel free to
post here.
