How to display errors using Page_Error event of Page Object

VB.NET

Private Sub Page_Error(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Error
        	Response.Write(Server.GetLastError().ToString)
        	Server.ClearError()
End Sub

C#

//In InitializeComponent 
this.Error += new System.EventHandler (this.Page_Error );

//
private void Page_Error(object sender, System.EventArgs e   ) 
{
	Response.Write(Server.GetLastError().ToString());
	Server.ClearError ();
}

In the Same manner handle the Errors in the Application_Error event in global.asax
