Dim zip As New Chilkat.Zip()

Dim success As Boolean

'  Any string unlocks the component for the 1st 30-days.
success = zip.UnlockComponent("Anything for 30-day trial")
If (success <> true) Then
    TextBox1.Text = TextBox1.Text & zip.LastErrorText & vbCrLf
    Exit Sub
End If


success = zip.NewZip("test.zip")
If (success <> true) Then
    TextBox1.Text = TextBox1.Text & zip.LastErrorText & vbCrLf
    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
recurse = true
success = zip.AppendFiles("c:/temp/a/*",recurse)
If (success <> true) Then
    TextBox1.Text = TextBox1.Text & zip.LastErrorText & vbCrLf
    Exit Sub
End If



success = zip.WriteZipAndClose()
If (success <> true) Then
    TextBox1.Text = TextBox1.Text & zip.LastErrorText & vbCrLf
    Exit Sub
End If


MsgBox("Zip Created!")
