Derek,

I too have worked with this API and got bogged down when it came to 
retrieving the full path from the ITEMIDLIST structure.  Here's the code 
up to where I left off (I was having trouble getting the length of the 
first item in the list):

include win32lib.ew
with trace

atom xSHBrowseForFolder, binfo, result, rtn_code, cb1, cb2
sequence folder, folder_path

xSHBrowseForFolder = registerw32Function(shell32, "SHBrowseForFolder", 
{C_POINTER}, C_POINTER)

global constant
bfOwner = allot( Long ),
bfpidlRoot = allot( Long ),
bfDisplayName = allot( Lpsz ),
bfTitle = allot( Lpsz ),
bfFlags = allot( Long ),
bfFunction = allot( Long ),
bfParam = allot( Long ),
bfImage = allot( Long ),
SIZEOF_BROWSEINFO = allotted_size()

binfo = acquire_mem(0, SIZEOF_BROWSEINFO)

store( binfo, bfOwner, 0)
store( binfo, bfpidlRoot, NULL)
store( binfo, bfDisplayName, "")
store( binfo, bfTitle, "Select a Folder")
store( binfo, bfFlags, NULL)
store( binfo, bfFunction, NULL)
store( binfo, bfParam, NULL)
store( binfo, bfImage, NULL)

result = w32Func(xSHBrowseForFolder, {binfo})
folder = fetch( binfo, bfDisplayName )
trace(1)
cb1 = peek(result)
cb2 = peek(result)
folder_path = peek({result+2,cb1-2})
rtn_code = message_box("Folder: " & folder_path, "Test", MB_OK)
release_mem(binfo)

With this code the dialog does appear and you can select a folder but I 
can't seem to figure out how to get the path from "result".  I will keep 
plugging away and maybe between the two of us we can figure it out.  I 
have some places where I would also like to select a folder.
