Dim crypt As New Chilkat.Crypt2
Dim zip As New Chilkat.Zip

Dim success As Boolean
success = zip.NewZip("test.zip")
If (success <> True) Then
    System.DebugLog(zip.LastErrorText)

// Add the bytes 0x00 0x01 0x02 0x03 ... 0x0F as a file in the .zip
Dim binFileData As MemoryBlock
binFileData = crypt.Decode("000102030405060708090A0B0C0D0E0F","hex")
Dim entry As Chilkat.ZipEntry
entry = zip.AppendData("binaryData.dat",binFileData)

// Add the string "Hello World!" to the .zip
entry = zip.AppendString2("helloWorld.txt","Hello World!","utf-8")

Dim zipFileInMemory As MemoryBlock
zipFileInMemory = zip.WriteToMemory()

// We could save these files to a file, and it is a valid .zip
Dim fac As New Chilkat.FileAccess
success = fac.WriteEntireFile("test.zip",zipFileInMemory)
If (success <> True) Then
    System.DebugLog(fac.LastErrorText)
    Return
