Forms Authentication Against An XML File
By Orcs Web, published on 17 Jan 2005
This code shows how to validate against an XML file for Forms Authentication security in ASP.Net. Please read one of the earlier articles on Forms Authentication for an introduction and to see the required settings in the web.config file. The code below is just a modification of the login.aspx page.
<%@Page Language="VB" Trace="false"%>
<%@ Import Namespace="System.Web.Security" %>
<%@ Import Namespace="System.Xml" %>
<script language="VB" runat=server>
Sub ValidateLogin(Src as Object, E as EventArgs)
Dim sXmlPath As String = "C:\Inetpub\wwwroot\users.xml"
Dim oXmlDoc As New XmlDocument()
Try
oXmlDoc.Load(sXmlPath)
Catch oError As Exception
StatusMessage.innerHTML = "There was an error:<BR>" & oError.Message & "<BR>" _
& oError.Source & "."
Exit Sub
End Try
Dim oXmlUser As XmlNodeList
oXmlUser = oXmlDoc.GetElementsByTagname(txtUser.Value)
If Not (oXmlUser Is Nothing) Then
If txtPwd.Value = oXmlUser(0).FirstChild().Value Then
FormsAuthentication.RedirectFromLoginPage(txtUser.Value, false)
Else
StatusMessage.InnerHtml = "Invalid login"
End If
End If
End Sub
</script>
