//
// instance - The instance handle of the control panel containing the applet.
//
// parent - Contains the handle of a parent window for the applet (if any).
//
// cmdline - Points to the command line for the applet (if available).
// If the applet was launched without a command line,
// 'cmdline' contains NULL.
