An ACommonDialog consists of a standard set of dialog boxes for operations such as opening and saving files, setting print options, and selecting colors and fonts. The control also has the ability to display help by running the Windows Help engine. From ATEasy 51, this also allows to select directory See the property OpenOptions for example.
The ACommonDialog control provides an interface between ATEasy and the routines in the Microsoft Windows dynamic-link library Commdlg.dll.
You use the ACommonDialog control in your application by adding it to a form and setting its properties. The dialog displayed by the control is determined by the methods of the control. At run time, a dialog box is displayed or the help engine is executed, when the appropriate method is invoked. At design time, the ACommonDialog control is displayed as an icon on a form. This icon can't be sized.
The ACommonDialog control automatically provides context sensitive help on the interface of the dialog boxes by clicking:
The WhatsThisHelp button in the title bar, then clicking the item for which you want more information.
The right mouse button over the item for which you want more information, then selecting the What's This command in the displayed context menu.
The operating system provides the text shown in the Windows Help popup.
Note: There is no way to specify where a dialog box is displayed.
