GetOpenFileName API Hooks

[SammyB]

I am trying to get back to the way Office 97 allowed multiselect in GetOpenFileName: the order you selected was the order returned. This means that I must keep my own list of files which changes whenever the user changes the selection. I started with Dev Ashish's code for the GetOpenFilename API, http://www.mvps.org/access/api/api0056.htm. In the hook proc whenever I get a CDN_SELCHANGE notification, I send a CDM_GETSPEC msg to the parent to get the current list of files. The first one in the list seems to be the most recently selected, so I can construct an ordered list as long as the
user ctrl-clicks.

The problem is when the user shift-clicks. In order to construct a list, I need to get the complete list of files for the current directory which is in the listbox and also get it in the order that it is in the listbox. I have tried to send the listbox a WM_GETTEXT message, but I do not get a response: probably I have the wrong hWnd. I am getting the hWnd with

hWndList = FindWindowEx(hWndParent, 0, "SHELLDLL_DefView", vbNullChar)
 

How should I get the handle and/or the list?

Note, I get the directory name whenever the user changes it via the CDN_FOLDERCHANGE notification and the CDM_GETFOLDERPATH msg, but I cannot just use dir to get the file list, because it may be in the wrong order. I have to get it from the dialog's listbox.
