12.6 Summary

 There are various DDX_OC functions used to exchange data between a property of an OLE
control in a dialog box, form view, or control view object and a data member of the dialog
box, form view, or control view object.
 When we insert a command into a menu, it would trigger a call to DialogBox(), or a
derivative, in our command message handling code.

 In our main application, we need to modify our menu and/or toolbar to add a command
to activate our dialog box.
 Global variables can be read or modified by any part of the program, making it difficult
to remember or reason about every possible use.
 Modal dialog boxes (also called as Application Modal dialog box) insist you to respond to
them before continuing in the same application.

 Modeless dialog boxes are just like any other form in your application and loose their
focus as soon as you click some other Window outside the application.

 A System Modal dialog box restricts the user from continuing work on the system unless
it gets unloaded.
 You create a modeless dialog box by means of the CreateDialog function, mentioning the
identifier or name of a dialog box template resource and a pointer to the dialog box
procedure.
