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.

The buf2dword() added. I'll check what possibly could be wrong with the SHBrowseForFolder call.
