This is what I want to do.
I have an MDI Style app, The processes are 'Orders', 'Customers'. these are two mdi child forms that have a details of orders, customers. Each one have Add, Modify
What I want is If yo click Add in orders, display the Add orders Child form on top of Orders form i dont permits to focus the order form until the add work is done. But it permits to open the Customer form without problems. ('The same for customers')
