It may just be me here, but does n-tier architecture not normally refer to the separation of your code, i.e. something like UI code, business logic and some kind of data access layer?
|

|
|
|
iam sorry still iam not clear
can u plz elaborate
|
|

For three tier you app should be in differen modules (as explained by Paddy Boyd)
1- DAL Data Access Layer
2- BLL Business Logic Layer
3- PL Presentation layer
each layer functionality can be handeld sepratley.

a three tier or not Y or N

Hi,
I am creating a webapp and would like to pass some values to each page via the querystring. The reason for this is so that that people can access certain sections by typing in the URL. At some point I will also implement URL rewriting to help achive this.
What I want to know is if there is any way to automatically add those parameters to the querystring without me having to specifiy them i.e. If I enter the link in my source as ~/default.aspx the url should automatically get something like ?lang=en&country=za. If this is in one centralised place then making any changes in the future would also be easier.
I think I probably have to create an httpmodule but I'm not sure. Any help apprceiated.

Could you not just create a class that has a redirect method - this method will retrieve whatever you defualt values are from whereever you are storing them and then call a response.redirect.
Then instead of calling response.redirect from your code you just call aClass.Redirect or something like that. Bit simpler than creating a Http module.
|
|
|
|
|
If I do a response.redirect I lose any form values that may have been posted. I preferably don't want to even have to enter a URL as navigateURL=ChangeURL(URL), I'd rather have it happen automatically in case I forget.

I am using .NET 2.0 C#. How can I check what time the user log in. And greet the user "Good Morning, name" etc. Do I need to set the time for morning, afternoon and evening? Or .NET has its property set.
Example:
Morning 12am-11.59am
Afternoon 12pm-4pm
etc
thanks in advance. Much appreciated.

Dont think thers any specific function that will do it. Alternatively you could just get the DateTime.Now.Hour and use a condition

Thanks. I did a if else.
thanks in advance. Much appreciated.

no s at the end of Subscription

Something looks like:
FormView1.DefaultMode = FormViewMode.Insert; Also, you might want to check out the ChangeMode method to change the current mode of the control.
