The LoadFromURL method is used to update an ActiveX control with data from a file, ASPX, or ASP page from a server.

If szURL represents a simple file, it should be the product of a PEsavetofile method call.

If szURL represents an ASPX page, the server page should contain a ProEssentials WebForm control (except a PedoWeb lwhich is only used for appending) with it's RenderingType property set to BinaryDataStream. This enables client-side code to update a client-side ActiveX with data from the server. Example code for use of this method can be found within the included VB.NET_WebDemo, Walk-Through3.

If szURL represents an ASP page, the server page should contain and ProEssentials ActiveX control and output its data via the SaveToStream method. This enables client-side code to update a client-side ActiveX with data from the server. Example code for use of this method can be found in the topic SaveToStream.
