How to cast the arguments in the MdiChildActivate event?

[Ronny Van Assche]

Hi,

I am working with an Mdiform and several Childforms who are loaded
dynamically with reflection.
Every time a child is getting activate i must reinitialize the menu.
(i think) This is something to handle in the MdiChildActivat e event of the
MdiForm.

My problem now is to get the initial properties of the active child.
When i try to cast the "e" arguments to
((System.Window s.Forms.Form)e) .GetHashCode() it gives me a compile error
"Cannot convert type 'System.EventAr gs' to 'System.Windows .Forms.Form".

Now the question. What is the correct cast for this?

Kind regards,

Ronny

Ronny,

The EventArgs instance that was passed in doesn't have any information
about the child being activated. Also, it is of type EventArgs, which can
not be cast to a type of System.Windows. Forms.Form. You will have to get
the active mdi child using the MDI parent form's ActiveMdiChild property.

Hope this helps.
