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

loCrypt = CreateObject('Chilkat.Crypt2')
loZip = CreateObject('Chilkat.Zip')

lnSuccess = loZip.NewZip("test.zip")
IF (lnSuccess = 0) THEN
    ? loZip.LastErrorText
    RELEASE loCrypt
    RELEASE loZip
    CANCEL

* Add the bytes 0x00 0x01 0x02 0x03 ... 0x0F as a file in the .zip
loBd = CreateObject('Chilkat.BinData')
loBd.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex")
loZip.AddBd("binaryData.dat",loBd)

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

loZipFileInMemory = loZip.WriteToMemory()

* We could save these files to a file, and it is a valid .zip
loFac = CreateObject('Chilkat.FileAccess')
lnSuccess = loFac.WriteEntireFile("test.zip",loZipFileInMemory)
IF (lnSuccess = 0) THEN
    ? loFac.LastErrorText
