Closed event not fired when form hidden.

[GlynA]

I have a problem in a VB.NET application where the Closed event is not fired when I used the Close method on a form which has previously been hidden. Simply showing the form again before closing it makes no difference. The form is an MDI parent - I do not know if that is significant.
Also, I notice that if I show the form again after hiding it then the close gadget does not work.

Has anyone seen this problem or have any ideas how to address it?

Glyn,

I have seen this happening even with forms which are not MDI. And as a work around I started using the event OnHandleDestroyed which is guaranteed to fire when you close out of a window.

Thanks for the suggestion Kris,

I have now changed the application to close the form rather than hiding it. This resolves both the problem with the close gadget and the lack of the closed event.

I would still be interested to hear if anyone else has come across these problems.
