Unfortunately there is no other way. Take a look,

attachfile.ascx

No. Check the Default.aspx code at post #6.

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>
[B]<%@ Register src="attachfile.ascx" tagname="attachfile" tagprefix="uc1" %>[/B]

Then you should consider switching your major.
