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

Dim xmp As Chilkat.Xmp
Set xmp = Chilkat.NewXmp

' The first step is to create a new XMP document, which is nothing
' more than XML.  The NewXmp method returns an XML document with
' the standard XMP boilerplate.  
Set xml = xmp.NewXmp()

' Add some properties...

success = xmp.AddSimpleStr(xml,"Iptc4xmpCore:Chilkat","Blah blah")
' If you wish to view the XML, save it to a file and review it
' with a text editor:
success = xml.SaveXml("newXmp.xml")
If (success <> True) Then
    Debug.Print xml.LastErrorText
    Exit Sub
End If

' To add the XMP to the JPG (or TIFF), simply load the JPG,
' append the XMP, and save:
success = xmp.LoadAppFile("scream.jpg")
If (success <> True) Then
    Debug.Print xmp.LastErrorText
    Exit Sub
End If

success = xmp.Append(xml)
If (success <> True) Then
    Debug.Print xmp.LastErrorText
    Exit Sub
End If

success = xmp.SaveAppFile("screamOut.jpg")
If (success <> True) Then
    Debug.Print xmp.LastErrorText
    Exit Sub
End If
