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

$crypt = New-Object Chilkat.Crypt2
$zip = New-Object Chilkat.Zip

$success = $zip.NewZip("test.zip")
if ($success -eq $false) {
    $($zip.LastErrorText)

# Add the bytes 0x00 0x01 0x02 0x03 ... 0x0F as a file in the .zip
$bd = New-Object Chilkat.BinData
$bd.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex")

# Add the string "Hello World!" to the .zip
$zip.AddString("helloWorld.txt","Hello World!","utf-8")

$zipFileInMemory = $zip.WriteToMemory()

# We could save these files to a file, and it is a valid .zip
