Hi,
Don't know about VFP7, but in VFP6 IDispatch is an Object. And this code works:

osvg= CREATEOBJECT("Adobe.svgctl")
osvg.Src = GETFILE("svg")
oSVGDoc = osvg.GetSVGDocument()
? oSVGDoc.URL

>I'm not sure what an IDispatch is but, I'm tryinig to use the SVG viewer 3.0.
>To access the document I use the getsvgdocument method which returns IDispatch.
