Keep Dialog window in bounds of an app

[Jeff]

I have a MDI application.
I open a Form (Data Window) which has the apps window as the MDIParent.
From this Data Window I open a Dialog Window.

This Dialog window can float outside of the bounds of the App window.
How can I keep the dialog window within the bounds of my app.

I'm not an expert on this but in the layout properties of the form you
should have an option for Start Position to center on the parent.
