please explain the scenario with some what more details so that it will be possible to give the desired solution. (i.e. how you want to display your "login form" either automatically after specified time or else after click on "loading form" or any control placed on "loading form")

Please explain your requirement with some more clarity.

that is not overriding because in overriding its required that the methods of the base class (that need to be override) should be re implemented in the child class. but here in my code i have not done this.
sorry but that's not the answer i m searching for.

hi Kunal,
thnx for a nice and detailed answer, but still i have one doubt in my mind that is: because both class MyCls1 and class MyCls2 are inheriting System.object class so that both have the same copy of methoods ("Equals", "GetHashCode", "GetType" and "ToString" ) inherited from System.object, but when we inheriting class MyCls1 into class MyCls2 then class MyCls2 will have the multiple copies of the above said methods (one from direct System.object and the other one is from class MyCls1) so when we will create the object and call above said methods then how the compiler is dealing with those ambiguous method callings.
(Ex: the same issue occurs in c++ and resolved by using virtual inheritance)
