The AskYesNo function presents a message box that displays a question that the end user can answer by clicking a Yes or No button. The AskYesNo message box contains four items:
| • | Question mark icon |
| • | Question text |
| • | Yes button |
| • | No button |
Note • The default title is Question. To change the contents of the title bar, call SetDialogTitle before calling AskYesNo.
The AskYesNo message box is created by a direct call to the corresponding Windows API function, which displays a system modal dialog. Once a modal dialog is displayed, it retains focus until the end user closes it.
Windows displays this dialog; therefore, the installation cannot change the text of the buttons on the dialog. Windows displays the button text—"Yes" and "No" on English-based systems—in the language of the operating system; no manual localization of this text is required. If you need to display a more flexible dialog, call a Windows API function directly or use a custom dialog.
