Hi
I'm trying to get data from a abstract class and use it in BLL class, problem is i cannot seem to pass the data over, the data i'm trying to get is:
protected static string CurrentMemberIpAddr from public abstract class MemberBrowserDetails
protected static string CurrentMemberBrowser from public abstract class MemberBrowserDetails
Which will be used instead of:
"TestIP", "TestBrowser" in CheckLoginUsernamePasswordBLL
I've attached the two classes
Can any help with this problem
Regards
George

        }
        protected static string CurrentMemberIpAddr
        {
            get { return HttpContext.Current.Request.UserHostAddress; }

        protected static string CurrentMemberBrowser
        {
            get { return HttpContext.Current.Request.UserAgent; }
        }

        {

Looking at your abstract class MemberBrowserDetails, all the Properties are marked "protected", this implies that they are only available to a class that inherits them.
As CheckLoginUsernamePasswordBLL doesn't implement the abstract class it cannot access it's members.

Making these properties public will allow all classes access to them, you could also mark them as internal the calling class be in the same assembly.

Hi johnaryan:

I had tried the code attached, but this did not work. So i added the code snippet "as is" when posted
The code attached does not insert the IPAddr or browser info.
