Before you begin:

Starting with VFP7 the original GETDIR function is changed to be a wrapper around the SHBrowseForFolder function.

My comment:
I use the GlobalFree function to release the allocated memory.

In Andrew Coates code this is
= CoTaskMemFree(lpIDList)
which is probably a better way.

The SHParseDisplayName translates the initial path to the pointer to an item identifier list (PIDL).

Windows Shell script:
oShell = CREATEOBJECT("Shell.Application")

oFolder = oShell.Application.BrowseForFolder(_screen.HWnd,;
        "Select Folder", 1, "c:\Program Files")

IF NOT ISNULL(oFolder)
        ? oFolder.self.Path
ENDIF

Hi,
Great function to document, I only think that the last update broke something. Function 'buf2dword' isn't defined and the call to SHBrowseForFolder gives an exception.
A.M. | 2005-05-23 07:25:32
The buf2dword() added. I'll check what possibly could be wrong with the SHBrowseForFolder call.
