Check or UnCheck iProperties “Date Created” and “Date Checked” example

By Wayne Brill

It is not obvious how to add or remove a check to an iProperty such as Creation Date:

In the VBA watch window you will see that when the "Date Created" iProperty is not checked the Expression property of the iProperty is not a valid date. When it is checked it has a valid date. If you give the iProperty Expression a valid date value it will be checked. Using a date value of "1601, 1, 1" removes the checkmark.  

Here is a VBA example:

Public Sub iProperties_Test()
    ' Get the active document.
    Dim invDoc As Document
    Set invDoc = ThisApplication.ActiveDocument
   
    ' Get the design tracking property set.
    Dim invDesignInfo As PropertySet
    Set invDesignInfo = invDoc.PropertySets.Item("Design Tracking Properties")
       
    Dim iProp As Property
    For Each iProp In invDesignInfo
        'If iProp.Name = "Date Checked" Then
        If iProp.DisplayName = "Date Created" Then
            'Property is unchecked with this
           ' iProp.Expression = "1601, 1, 1"
            'Property is checked with this
            iProp.Expression = #7/22/2016#
           
            Exit For
        End If
    Next iProp
   
End Sub
