# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$zip = New-Object Chilkat.Zip

# Initialize the zip object.  Because we will never actually write a zip file to the filesystem,
# the filepath passed to NewZip does not matter.
$success = $zip.NewZip("x.zip")
if ($success -ne $true) {
    $($zip.LastErrorText)
    exit
}

# Append a directory tree.  The call to 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 WriteBd, WriteZip, or WriteZipAndClose 
# is called, the referenced files are streamed and compressed
# into the .zip output file (or BinData object).

$recurse = $true
$success = $zip.AppendFiles("c:/temp/a/*",$recurse)
if ($success -ne $true) {
    $($zip.LastErrorText)
    exit
}

# Write the zip archive into the bdZip object.
$bdZip = New-Object Chilkat.BinData
$success = $zip.WriteBd($bdZip)
if ($success -ne $true) {
    $($zip.LastErrorText)
    exit
}

# We could directly access the bytes of the zip archive, or perhaps
# get the zip bytes in base64 format.
$zipAsBase64 = $bdZip.GetEncoded("base64")
$($zipAsBase64)

# Or the zip can be used by some other Chilkat method call that accepts
# a BinData object as an argument.
