To enable the following commands on the menu:
- Import Binary Data for Current Field
- Export Binary Data for Current Field
- Delete Binary Data for Current Field
- View Binary Data for Current Field
For a component bound to a binary property, you must set the BLOBFORMAT( ) parameter for the component. During import and export operations, Windows client displays in the open and save dialog boxes only files with the extension specified by the parameter. In the view operation, Windows client creates a temporary file with the extension specified by the parameter and then opens it with the program associated with this extension.
