Hi guys,

I am trying to add shared members in derived classes and use that values in base classes...

I have base

class DBLayer
    public shared function GetDetail(byval UIN as integer)
    dim StrSql = string.format("select * from {0} where uin = {1}", tablename, uin)
    ....
    end function
end class

my derived class

class User inherits dblayer
    public shared tabledname as string = "users"
end class

class item inherits dblayer
    public shared tabledname as string = "item"
end class

class category inherits dblayer
    public shared tabledname as string = "category"
end class

currently there is error using the tablename variable of derived class in base class but i want to use it... coz i dun know other techniques... if other solutions are better then u can post it or u can say how can i make it work? confused...
