PromptForFileName is a Boolean function used to display an Open or Save dialog using the values passed as arguments to the routine. It creates a TOpenDialog or a TSaveDialog instance for use in the routine. The AIsSaveDialog argument determines which dialog class is used in the routine.
Argument values are assigned to the corresponding properties in the dialog class. The Execute method in the dialog class is called to perform file selection or creation as needed, and its return value is used as the return value for the routine. The return value is True when the Execute method for the dialog class returns True.
AFilename contains the initially selected file name in the dialog, and is updated with the value selected using the dialog. A default value is not provided for the argument. If the dialog returns True, the FileName property in the dialog class is assigned to the AFileName argument.
AFilter contains file masks that can be selected in the dialog. The default value is an empty string ('') and causes the all files mask ('*.*' or '*') to be used. See TFileDialog.Filter for more information about the notation allowed in the argument.
ADefaultExt contains the file extension used for the file name selected in the routine. The default value for the argument is an empty string ('') and indicates that a default file extension is not used. See TFileDialog.DefaultExt for more information about default extensions.
ATitle contains the caption displayed on the dialog. The default value is an empty string ('') and allows the default value provided by the dialog class to be used.
AInitialDir indicates the initial directory when the dialog is displayed. The default value is an empty string ('') and causes the current directory in the application to be used as the initial directory in the dialog.
