Dim xmp As New ChilkatXmp

' Load a JPG or TIF image file.
Dim success As Long
success = xmp.LoadAppFile("qa_data/xmp/AJ_123642_1511.tif")
If (success <> 1) Then
    Debug.Print xmp.LastErrorText
    Exit Sub
End If

Debug.Print "Num embedded XMP docs: " & xmp.NumEmbedded

' This example assumes that XMP metadata is already present in the image file.
If (xmp.NumEmbedded = 0) Then
    Debug.Print "No XMP metadata already exists.."
    Exit Sub
End If

' Get the XMP metadata.
Dim xml As ChilkatXml
Set xml = xmp.GetEmbedded(0)

' Show the XML:
Debug.Print xml.GetXml()

' Update (overwrite) a string property.
success = xmp.AddSimpleStr(xml,"NumberofTimes","123")

success = xmp.SaveAppFile("qa_output/updated.tif")
If (success <> 1) Then
    Debug.Print xmp.LastErrorText
    Exit Sub
End If

Debug.Print "Success."
