Project-specific differences are noted where appropriate.
In InstallScript projects, FeatureIsItemSelected determines the current selection state of the specified feature. In InstallScript MSI projects, FeatureIsItemSelected determines the current installed state of the specified feature. You can also use FeatureGetData to determine if a feature is selected.
FeatureIsItemSelected is typically called to perform feature-specific tasks before or after file transfer. To perform feature-specific tasks during file transfer in an InstallScript installation, it is recommended that you place code in feature event handler functions.
