Design Property (as Boolean)

This Window property can only be set in the Inspector and is not available in code.

If True, an instance of the window can be instantiated implicitly. Set ImplicitInstance in the Properties Inspector in the IDE.


For example, an implicit instance is instantiated by referring to one of its properties or by calling its Show method. That is, a statement such as:




will instantiate the window only if ImplicitInstance is True. The default is True. If False, you need to instantiate it explicitly via the New operator. That is, only a statement such as:

w = New Window2

will instantiate the window.

If ImplicitInstance is False, statements such as:


and references to any window or control properties will produce an error.
