Right. You would create it as a custom property. Form|Add Property. I'd add it to my form baseclass.

If you go this route, please do make sure you set the property to .NULL. in the destroy of the form. If you don't, when you close the form, it won't really release because there will be an orphaned reference to the object in .oLastActive.

Post back here if you need more details if you chose this route.
