The VolumeCostList control presents information about the cost associated with the selection on the different drives. It shows all the drives involved in the current installation plus all drives that are of the types chosen in the Drives to Display area of this dialog. If the required disk space exceeds the amount available on some drive, it is highlighted in the control.

The following localizable string identifiers are used for the column headings in the control:

UITextVolumeCostVolume

UITextVolumeCostSize

UITextVolumeCostRequired

UITextVolumeCostDifference

UITextVolumeCostAvailable

 

The following four localized strings are used in formatting the size of a file:

bytes

KB

MB

GB

 

Note: The installer does not update the content of the VolumeCostControl when a user enters a different path into a PathEdit control, browse dialog box, DirectoryList control, or DirectoryCombo control because there is no property associated with this control.

Text

Text:

The font, font style, and column widths to use for the control. Text styles can be managed in your project on the Styles dialog (Project > Styles).

To set the column widths in the VolumeCostList control, append the column widths to any font specification. Column widths are entered as a series of positive integers enclosed in curly braces. Empty curly braces or {0} hide the column. A negative number or a string that cannot be converted into a positive integer is an invalid column width. When an invalid column width is encountered in the series, the remaining columns are hidden. A maximum of five column widths can be specified.

Example: (the last column is set to be hidden)

{\UI_Font_Normal}{40}{55}{60}{60}{0}
