VBASigned Property

True if the Visual Basic for Applications project for the specified workbook has been digitally signed. Read-only Boolean.

Example

This example loads a workbook named “mybook.xls” and then tests to see whether its Visual Basic for Applications project has a digital signature. If there’s no digital signature, the example displays a warning message.

Workbooks.Open FileName:="c:\My Documents\mybook.xls", _
    ReadOnly:=False
If Workbook.VBASigned = False Then
    MsgBox "Warning! The project " _
    "has not been digitally signed." _
    , vbCritical, "Digital Signature Warning"
End If
