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

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Zip")
set zip = Server.CreateObject("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 <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( zip.LastErrorText) & "</pre>"
    Response.End
End If

' 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 = 1
success = zip.AppendFiles("c:/temp/a/*",recurse)
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( zip.LastErrorText) & "</pre>"
    Response.End
End If

' Write the zip archive into the bdZip object.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.BinData")
set bdZip = Server.CreateObject("Chilkat.BinData")
success = zip.WriteBd(bdZip)
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( zip.LastErrorText) & "</pre>"
    Response.End
End If

' We could directly access the bytes of the zip archive, or perhaps
' get the zip bytes in base64 format.
zipAsBase64 = bdZip.GetEncoded("base64")
Response.Write "<pre>" & Server.HTMLEncode( zipAsBase64) & "</pre>"

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