Modal and Modeless Dialog Boxes
You can use class CDialog to manage two kinds of dialog boxes:
Modal dialog boxes, which require the user to respond before continuing the program
Modeless dialog boxes, which stay on the screen and are available for use at any time but permit other user activities
The resource editing and procedures for creating a dialog template are the same for modal and modeless dialog boxes.
Creating a dialog box for your program requires the following steps:
Use the dialog editor to design the dialog box and create its dialog-template resource.
Create a dialog class.
Connect the dialog resource's controls to message handlers in the dialog class.
Add data members associated with the dialog box's controls and to specify dialog data exchange and dialog data validations for the controls.
