本文介绍了两种类型的对话框：模态对话框和非模态对话框，并详细阐述了它们的特点及创建过程。模态对话框要求用户响应才能继续程序运行；而非模态对话框则允许用户同时进行其他操作。创建对话框需要使用对话编辑器设计模板资源，并通过ClassWizard创建对话类、连接控件到消息处理程序等步骤。

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 ClassWizard 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.
Use ClassWizard to create a dialog class.
Use ClassWizard to connect the dialog resource’s controls to message handlers in the dialog class.
Use ClassWizard to add data members associated with the dialog box’s controls and to specify dialog data exchange and dialog data validations for the controls.
