Dim zip As New ChilkatZip

Dim success As Long
success = zip.NewZip("test.zip")
If (success <> 1) Then
    Debug.Print zip.LastErrorText
    Exit Sub
End If

' Create a string array object with our set of filename patterns
' to be excluded:
Dim sa As New CkStringArray
success = sa.Append("*.bak")
success = sa.Append("*.tmp")

' Tell the zip object to use these exclusions:
zip.SetExclusions sa

' Append a directory tree.  The AppendFiles does
' not read the file contents or append them to the zip
' object in memory.  It simply appends references
' to the files so that when WriteZip (or WriteZipAndClose,
' or WriteExe, etc.) is called, the files are compressed
' and encrypted.
Dim recurse As Long
recurse = 1
success = zip.AppendFiles("/temp/a/*",recurse)

Dim success As Long
success = zip.WriteZipAndClose()
If (success <> 1) Then
    Debug.Print zip.LastErrorText
    Exit Sub
End If

Debug.Print "Zip Created!"
