So when you call ParentDelegate() from Form2, it will call private method InformParent() which is in Form1 My Website | Ask smart questions

Thanks again will try with delegate first C#

Sure Will do so ......thanks again :) :) C#

You should use it instead of Int.Parse() Have a look at documentatio in MSDN, it shows how to use Int.TryParse() #region signature my articles #endregion

IF you are referencing a static method the class must be known, if you are using an instance method, the instance should be known (and definately NOT null). xacc.ide The rule of three: "The first time you notice something that might repeat, don't generalize it. The second time the situation occurs, develop in a similar fashion -- possibly even copy/paste -- but don't generalize yet. On the third time, look to generalize the approach."

Why didn't you just edit the post? --- "Anything that is in the world when you're born is normal and ordinary and is just a natural part of the way the world works. Anything that's invented between when you're fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. Anything invented after you're thirty-five is against the natural order of things." -- Douglas Adams

It also lets you store a collection of 'Animals' in a collection without having to have a collecton of dogs, a collection of cats, a collection of llamas, a collection of...I think you know where I am going. You can just have a collection of Animals, and add any class dervied from Animal to it. class Animal {}; class Cat : Animal {}; class Dog : Animal {}; List<Animal>_myListOfAnimals = new List<Animal>(); Animal myCat = new Cat(); //assume Cat derived from Animal Animal myDog = new Dog(); //assume Dog derived from Animal _myListOfAnimals.Add( myCat ); _myListOfAnimals.Add( myDog ); Saying this, if you are using inheritence just to have this ability, then interfaces are the way to go.

It would make life easier." - comment posted on WTF "This time yesterday, I still had 24 hours to meet the deadline I've just missed today."

just replace add method with public int add(int x,int y) { return x+y; } And remove the global variable result from the code

what are the times that we create an object to call a method:: i know that we do so wen we have to 1) call a method from another class and 2)to call a nonstatic function into a static function again we create an object. otherthan these what are the other instances we do so ...... thanks C#
