recursing into subdirectories

Hi.

I would be eternally grateful if someone could point me in the right
direction for this. I can't find it on the FAQ.

I am using the info-zip DLLS from visual basic using a wrapper from
vbaccelerator.com, but I don't think the problem is in the VB code.

say I have a zip file who's root directory is c:\temp and I want to add the
'foo' subdirectory and eveything in it. in my zip file I want to paths to
look like this

foo/file1
foo/subdir/file2

my pseudocode looks like this:

let root dir = "c\:temp"
let recurse subdirectories = true
let store foldernames = true
let store directories = true
add file spec "foo\*.*"

in the zip file, I just get the contents of the foo directory but no
subdirectories (in the above example I just get file1 with no directory
path)

if I set the file spec to '*.*' everything works fine (except, of course,
that I get all the other subdirectories of temp when I only want foo)

I have tried this with winzip and I notice it is possible to do this by
dragging and dropping but not with the 'add files' dialog. of course, I
don't know what info-zip calls winzip is making so it doesn't really help me
much

many thanks in advance
