[RESOLVED] [2005] Sharing control but preventing dispose?

[Bulldog]

I have a form with various controls, one of which is a combobox (called "C") which has some significant code behind it.

In a mode of the app, I open a sub-form and need that same combobox on it, rather than copy all of the code into the sub-form, in the load event of the sub-form I did;

Dim CBox As New ComboBox
CBox = Main.C

Which is great, since the sub-form now has the ComboBox and it works fine, I have only one set of code for it too. However... when I close the sub-form with Me.Close and go back to the main form, the ComboBox Main.C is now gone, presumably it was disposed of when the sub-form was closed.

How can I prevent this? I'm assuming there must be a way of sharing controls between forms without having to duplicate them?
