Recursively appends files in a directory tree and writes a zip archive into a Chilkat BinData object.

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

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

Dim recurse As Boolean
recurse = True
success = zip.AppendFiles("c:/temp/a/*",recurse)
If (success <> True) Then
    System.DebugLog(zip.LastErrorText)
    Return
End If

// Write the zip archive into the bdZip object.
Dim bdZip As New Chilkat.BinData
success = zip.WriteBd(bdZip)
If (success <> True) Then
    System.DebugLog(zip.LastErrorText)
    Return
End If

// We could directly access the bytes of the zip archive, or perhaps
// get the zip bytes in base64 format.
Dim zipAsBase64 As String
zipAsBase64 = bdZip.GetEncoded("base64")
System.DebugLog(zipAsBase64)

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