title: How can I change extended file properties using vba
body: <p>Using <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/bb787870%28v=vs.85%29.aspx" rel="nofollow">this link</a> I was able to write a program in vba that reads extended file properties.  Now, I'd like to make a program that can edit extended file properties - specifically property 22, the "subject" of a file.  So, given a file path, how could you edit the subject associated with that file?</p>
