PropertySets Failing to Access iProperties

[richard.joseph.pollak]

I am trying to compare expression values in my iProperties, but some of the default iProperties have been giving me trouble.

Does anyone know why I am getting an error?

oPropSet = ThisDoc.Document.PropertySets.Item("Design Tracking Properties")

MessageBox.Show(oPropSet.Item("Description").Expression)
MessageBox.Show(oPropSet.Item("Project").Expression)
MessageBox.Show(oPropSet.Item("Checked By").Expression)
'The following returns an error:
MessageBox.Show(oPropSet.Item("Eng. Approved By").Expression)

Here is the error:

Unspecified error (Exception from HRESULT: 0x80004005 (E_FAIL))

System.Runtime.InteropServices.COMException (0x80004005): Unspecified error (Exception from HRESULT: 0x80004005 (E_FAIL))

It seems that isn't the correct item name. My cheat sheet shows "Engr Approved By".

Here is a copy of the iProperties list from an AU pdf I found.

Now that I think about it, I remember having this issue before because the label in the iProperties dialog do not match the item name in the API.

oPropSet = ThisDoc.Document.PropertySets.Item("Design Tracking Properties")

search = True
i = 1
Do While search = True
	Try
		MessageBox.Show(oPropSet.Item(i).Name)
	Catch
		search = False
	End Try
	i = i + 1
Loop

I was able to trouble shoot using the rule above. I learned that the name of "Eng. Approved By" is actually "Engr Approved By".

Go figure! Hopefully if anyone else comes across this problem they will find this post.
