EXAMPLE
Example code for the CFormPos class

To try this example, do the following:
1. Create a new form (be sure to leave the form's StartupPosition
property set to 3 - Windows Default
2. Paste all the code from this example to the new form's module
3. Run the form. If the form's previous position was saved,
it is restored on open. When the form is closed its position
is saved.
