VBA- digital signatures

If I create a VBA user form using EXCEL 2007 can the form itself be digitially signed by users of the form? I noticed if I decided to create an embedded form in EXCEL there is a way to add a digital signature control by selecting INSERT tab then signature line icon is located on the ribbon.


Thanks for your help.

@RoyUK - company already has digital signatures in place.

@snb - can you please explain attachment. thanks.

@snb...The attachment in the prior post is not what I am looking for.
Attached has two examples
1 - workbook has digitial signature line control if you right click there is an option in the context menu to add the digitial signature. Note my company already has the digitial id's created.

2 - VBA userform has a lablel control and textbox control

What I was lookng for is to some how do in the UserForm what is possible in the workbook

Note: attachment in Excel 2010 this is the version I have at home but at work where I am trying to accomplish this Excel 2007.

Thanks for our help.

Anyone, any ideas? when I click on the object browser in EXCEL VBA and search all libraries using the search word SIGN I see possible classes relating to signatures. How do I access or call these from my VBA code? Very new to VBA..

thanks in advance.

Found on MS Office page that only a word document or an excel workbook can contain digitial signature lines. Therefore the above can not be done on a userform.
