Hi somebody could help me, i need to create two classes only with this like reference:
Dim objA As A= New A()
Dim objB As B = objA.CreateObj()

I don´t know how class A creates the B object in its method.
I have not used OOP for a while, so any help will be grateful.

Thanks.

Solution 1

It is called factory method and (as correctly pointed out by Bruno Sprecher) is usually implemented as Shared method. This Code Project article however show many different ways a factory could be implemented: "Different ways of implementing factories"[^].

My 5 at least. Thanks for the note. I was not quite sure; therefore only a comment. But your answer reduces my uncertainty and gives real information.

Thanks guys.
My 5 too.
I saw this here and drive me here to request help: http://www.asppdf.com/manual_03.html

Specifically these two lines:
IPdfManager objPdf = new PdfManager();
IPdfDocument objDoc = objPdf.CreateDocument(Missing.Value);

Thanks for guide me.
