I designed a small app and I wanted to do a BrowseFolder (see
http://www.mvps.org/access/api/api0002.htm), basically do a file open
diaglog and select a directory/folder. The problem is that you can't
specify the starting folder.
Stephan Leban provided a neat solution that does allow me to browse using
a starting folder.
I am using A97 and it works fine. However, I put it onto a system that
uses AccessXP. And it chokes on references to VBA332.DLL. I searched the
drive on the XP system and there is no VBA332.DLL. That makes Stephan's
utility unworkable.
Is there anything I can use to substitute vba332.dll? Below are the
functions that make refererence to it. Does XP have a "built-in"
browsefolder command where one can specify a starting folder?

ByRef strFunctionId As String) As Long

(ByVal hProject As Long, ByVal strFunctionId As String, _
ByRef lpfn As Long) As Long
