Visual Basic example program to modify an XMP array property by removing some values and adding some others.

    ' Modify an array property.
    
    ' Create an instance of the XMP ActiveX and unlock it.
    Dim xmp As New ChilkatXmp
    success = xmp.UnlockComponent("anything for 30 day trial")
    If (success = 0) Then
        MsgBox "Failed to unlock"
        Exit Sub
    End If
    
    ' Load a JPG file.
    success = xmp.LoadAppFile("IndependantPhotographer-Example.jpg")
     If (success = 0) Then
        MsgBox xmp.LastErrorText
        Exit Sub
    End If
   
   ' Get the 1st (and only) XMP in this JPG.
    Dim xml As ChilkatXml
    Set xml = xmp.GetEmbedded(0)
    If (xml Is Nothing) Then
        MsgBox xmp.LastErrorText
        Exit Sub
    End If
        
    ' Get the "dc:subject" array items.
    Dim sa As CkStringArray
    Set sa = xmp.GetArray(xml, "dc:subject")
    If (sa Is Nothing) Then
        MsgBox "dc:subject property not found"
        Exit Sub
    End If
    
    ' Prevent duplicates in the string array object by
    ' setting the Unique property
    sa.Unique = 1
    
    ' Remove a few items we don't want...
    sa.Remove "age"
    sa.Remove "beach"
    sa.Remove "nature"
    
    ' Add some...
    sa.Append "sand"
    sa.Append "ocean"
    
    ' AddArray is a "replace" operation if the property already exists.
    xmp.AddArray xml, "bag", "dc:subject", sa
    
    ' Save the XML to review if desired.
    xml.SaveXml "out.xml"
    
    ' Save the JPG with the dc:subject modified.
    xmp.SaveAppFile "out.jpg"
