How to insert File into Database using SqlDataSource control in ASP.Net

Hi,

I want to insert a .rar file into my database, i tried many times, but i couldnt.

May you help me please? 

The database is called db_AkiraNetwork

The table is called tbl_driver:

iddriver - int - PK and Auto Increment

tipo - nchar(15)

so - nchar(10)

arquitectura - nchar(3)

ficheiro - varbinary(MAX)

The code i made in ASP is:

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="adddriver.aspx.cs" Inherits="admin_adddriver" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:FormView ID="fvAddDriver" runat="server" DataKeyNames="iddriver" DataSourceID="SqlDSAddDriver" DefaultMode="Insert">
<InsertItemTemplate>
Tipo:
<asp:TextBox ID="txtTipo" runat="server" Text='<%# Bind("tipo") %>' />
<br />
Sistema Operativo:
<asp:TextBox ID="txtSO" runat="server" Text='<%# Bind("so") %>' />
<br />
Arquitectura:
<asp:TextBox ID="txtArquitectura" runat="server" Text='<%# Bind("arquitectura") %>' />
<br />
Ficheiro:
<asp:FileUpload runat="server" ID="fuFicheiro" Text='<%# Eval("ficheiro") %>'/>
<br />
<asp:Button ID="btnInsert" runat="server" CausesValidation="True" CommandName="Insert" Text="Inserir"/>
&nbsp;<asp:Button ID="btnCancel" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancelar" />
</InsertItemTemplate>
</asp:FormView>
<asp:Label ID="lblMensagem" runat="server" Text=""></asp:Label>
<asp:SqlDataSource ID="SqlDSAddDriver" runat="server" ConnectionString="<%$ ConnectionStrings:CSAkiraNetwork %>" InsertCommand="INSERT INTO [tbl_driver] ([tipo], [so], [arquitectura], [ficheiro]) VALUES (@tipo, @so, @arquitectura, @ficheiro)"
SelectCommand="SELECT * FROM [tbl_driver]"
UpdateCommand="UPDATE [tbl_driver] SET [tipo] = @tipo, [so] = @so, [arquitectura] = @arquitectura, [ficheiro] = @ficheiro WHERE [iddriver] = @iddriver">
<InsertParameters>
<asp:Parameter Name="tipo" Type="String" />
<asp:Parameter Name="so" Type="String" />
<asp:Parameter Name="arquitectura" Type="String" />
<asp:Parameter Name="ficheiro" Type="String" />
</InsertParameters>
<UpdateParameters>
<asp:Parameter Name="tipo" Type="String" />
<asp:Parameter Name="so" Type="String" />
<asp:Parameter Name="arquitectura" Type="String" />
<asp:Parameter Name="ficheiro" Type="Object" />
<asp:Parameter Name="iddriver" Type="Int32" />
</UpdateParameters>
</asp:SqlDataSource>
<br />
<br />
</asp:Content>
