Adding digital signature programmatically

Hi,
I have an application, developed in Delphi 6 using the Excel97 type
library, which creates excel workbooks dynamically.
I have to add digital signature to the macros that are added to these
workbooks and I noticed that this could be done manually in the VB
Editor for a whole VBA project.

Is there a way to have my macros digitally signed programmatically
(i.e. at the point when the workbook is being created by the Delphi
code)?

I am neither a VB, nor a security expert, so any hint will be greatly
appreciated, thanks!

One way is to start with an empty, signed, workbook, then provide the
name of that workbook to the Workbooks.Add method. You can then add
code to that workbook and save it, keeping the signature.

Thanks a lot, Stephen,

Your suggestion is what I actually resorted to doing.
It works well with Excel 2002, but Office 2003 seems to have different
ways of managing the stuff, as I can't seem to produce signed
workbooks on a machine with Excel 2003.

Still trying to find a way around that. If anyone has had a similar
problem, I'll be interested in hearing how you coped with it.

Thanks,
RIL
