如何从下载的ActiveX控件中知道URI

Question

I have .NET(C#) ActiveX contol that was downloaded into IE from some URI, for example http://somehost/controlfolder/mycontrol.dll . That control have to download files from host via relative URI. By URI 'files/file.ext' control have to download 'http://somehost/controlfolder/files/file.ext'.

How my control can know main part of URI to construct from relarive URI full URI?

UPD0: I'm using <object> tag for definition control in native html(without using ASP.NET).
UPD1: Is it possible to know server path without assigning public control property from Javascript?

Answer 1

Here are two ideas:

1. From javascript, set a property on your control to the root url. myControl.RootUrl = window.location.replace ("default.aspx", "");

2. From your aspx (or whatever engine you're using).

   <object codebase='http://somehost/controlfolder/mycontrol.dll' ...> <param name="RootUrl" value="<% =Request.ApplicationPath + "/controlfolder/" %>"/> </object>
