Using Multiple Forms

All Windows applications have two types of windows: normal windows and dialog boxes. A normal window provides the main user interface for an application. For example, if you use Word, you use a normal window for editing your documents.

On occasion, the application will display a dialog box when you want to access a special feature. This type of window “hijacks” the application and forces you to use just that window. For example, when you select the Print option in Word, a dialog box appears, and from that point on, until you close the dialog by clicking OK, Cancel, or the close box, you can’t go back and change the document the only thing you can use is the Print dialog box itself. Forms that do this are called modal. While they’re up, you’re in that mode.

Dialog boxes are discussed in more detail in Chapter 7. For now, you can focus on adding additional forms to your application.
