Dear jerry,
If you open "\aspuploader\include_aspuploader.asp", you can find the following code:
Public Function Render()
Response.Write(Me.GetString())
End Function
Public Function GetString()
GetString = Impl.GetString()
End Function
Render() and GetString() , it has same functionality, only usage is different.
<%=uploader.GetString() %>
or
<%uploader.render()%>
Thank you for asking
