Hi there,
I literally just started to develope my own application after working through the beginners guide to ASP.NET in
VB.NET to test what I had learnt. I have come across a problem.
When i am pulling user name and password from the database with the database string in the page code it is fine. but when i replace it with the ConfigurationSettings.AppSettings("connectionStrin g") it throws me errors. i have matched the syntax... this is my web.config
<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
<appSettings>
<add key="connectionString" value="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Inetpub\wwwroot\DJSTORE\database\store.m db"/>
</appSettings>
<system.web>
<authentication="Forms">
<forms name=".djstore" loginurl="admin/login.aspx" protection="Validation" timeout="999999" />
</authentication>
<authorization>
<allow users="*" />
<deny users="*" />
</authorization>
</system.web>
</configuration>
And this is my page so far:
<%@ Page Language="
VB" %>
<script runat="server">
' This is the code for the Login Button
Sub LoginBtn_Click(Sender as Object, E as EventArgs)
Dim UsersDB as System.Data.iDataReader
UsersDB = Users()
While UsersDB.Read
Dim UserLogin as String = UsersDB("UserName")
Dim UserPassword as String = UsersDB("UserPass")
Dim AdminLevel as String = UsersDB("UserLevel")
If (UserName.Text = UserLogin And UserPass.Text = UserPassword) Then
Dim UserNameCookie as New HttpCookie("UserNameCookie")
UserNameCookie.Value = UserName.Text
Response.Cookies.Add(UserNameCookie)
Dim UserLevelCookie as New HttpCookie("UserLevelCookie")
UserLevelCookie.Value = AdminLevel
Response.Cookies.Add(UserLevelCookie)
FormsAuthentication.RedirectFromLoginPage(UserName .Text, true)
Else
Msg.Text = "Invalid User Name or Password: Please try again!"
End If
End While
End Sub
' This creates the database connection and reads the information for admin logins
Function Users() As System.Data.IDataReader
Dim connectionString As String = ConfigurationSettings.AppSettings("connectionStrin g")
Dim dbConnection As System.Data.IDbConnection = New System.Data.OleDb.OleDbConnection(connectionString )
Dim queryString As String = "SELECT [UserDetails].[UserName],[UserDetails].[UserPass], [UserDetails].[UserLevel] FROM [UserDetails]"
Dim dbCommand As System.Data.IDbCommand = New System.Data.OleDb.OleDbCommand
dbCommand.CommandText = queryString
dbCommand.Connection = dbConnection
dbConnection.Open
Dim dataReader As System.Data.IDataReader = dbCommand.ExecuteReader(System.Data.CommandBehavio r.CloseConnection)
Return dataReader
End Function
</script>

cheers for any help, if it cant be done then i will just have to do it with the direct connection which is not really what i wanted.
Database Connection with Web.Config
