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

Dim zip As New Chilkat.Zip

Dim success As Boolean = zip.NewZip("test.zip")
If (success <> True) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
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 WriteZip or WriteZipAndClose 
' is called, the referenced files are streamed and compressed
' into the .zip output file.

Dim recurse As Boolean = True
success = Await zip.AppendFilesAsync("c:/temp/a/*",recurse)
If (success <> True) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


success = Await zip.WriteZipAndCloseAsync()
If (success <> True) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("Zip Created!")
