I'm trying to access the value held within a specific section of a Microsoft Outlook window (specifically when an email has been opened).

I can easily gain access to all handles of the main window and the specific children that I'm interested in, but have been unable to determine a method to access some lower level properties.  Specifically:  when a message is being read in plain text (converted from HTML), there is a clickable control item that allows the user to convert the view to HTML.  I'm trying to read the text within that control item.  So far, I can access the handle and class name of this 'sub-window' of the main window...but have been unable to access the specific property (value of the string held within) I'm looking for.

Is there a win32 function/method that would provide access to this data?  Am not interested in modifying the value, just being able to read what is there.

Thanks!
