So, back to the original question, there isn't a "preferred" practice. VB.Net allows you to benefit from both of the methods at the same time. Different languages use both to a greater or lesser extent but to ask "what is the recommended approach in .Net" is purely rhetorical, academic, and...
Because Implementation Inheritance does not always guarantee polymorphic subsititutability (i.e. just because TennisBall uses Ball as a base class does not always ensure Ball can be substituted by TennisBall), the tendency is more towards the use of delegates.

I am looking for help from anyone who has designed an undo manager.
I have a manager that will save the current form object to a stack array. I fire this method on every controls GotFocus event.

I have a form that consists of multiple copies of a user control (made itself of a label, a textbox and twenty checkboxes).

They then click a button and a page containing a list of items from the checklist box appears like this:

OK. Well your clue is in the needed DialogResult enumeration.
If lblStatusID.Text = "2" Then
Dim result As DialogResult
result = MessageBox.Show(... ... )
If result = DialogResult.OK Then....

If MessageBox.Show(" ... ", MessageBoxButtons.OKCancel, MessageBoxIcon.Information) then ...
and it should (hopefully) work.
