Can someone please tell me why I keep being redirected back to the login page
even though I have logged in with the correct cridentials!!!
I have used this code before on another site and it works fine but when I
copied it across to the new site it stops working! All the variables are
passed when I do a debug but it just returns me to the login page again and
again!
Please help! It's driving me nuts!
Thanks!!!
<<CODE>>>
If Page.IsValid Then
'Connect to Database for User Validation
If DBConnection(txtUserName.Text, txtPassword.Text) Then
FormsAuthentication.RedirectFromLoginPage(txtUserName.Text,
Remember.Checked)
Else
' Credentials are Invalid
lblMessage.Text = "Invalid Login!"
End If
End If
End Sub
Function DBConnection(ByVal txtUserName As String, ByVal txtPassword As
String) As Boolean
Dim Myconn As New
SqlConnection(ConfigurationSettings.AppSettings("strConn"))
Dim cmd As New SqlCommand("ValidateUser", Myconn)
cmd.CommandType = CommandType.StoredProcedure
Dim objParam1, objParam2 As SqlParameter
objParam1 = cmd.Parameters.Add("@UserName", SqlDbType.Char)
objParam2 = cmd.Parameters.Add("@Password", SqlDbType.Char)
objParam1.Direction = ParameterDirection.Input
objParam2.Direction = ParameterDirection.Input
objParam1.Value = txtUserName
objParam2.Value = txtPassword

Myconn.Open()
End If

Return True
