* NAME: ChangeAppIDLaunchAndActivateACL *
* --------------------------------------------------------------------------*
* DESCRIPTION: Modifies an AppID's launch access control list. *
* The system uses the AppID launch ACL to determine if a principal *
* (a user or group of users) is allowed to launch the COM server *
* associated with the AppID. *
* --------------------------------------------------------------------------*
* ARGUMENTS: *
* *
* tszAppID - The Application ID you wish to modify *
* (e.g. "{99999999-9999-9999-9999-00AA00BBF7C7}") *
* *
* tszPrincipal - Name of user or group (e.g. "redmond\johndoe") *
* *
* fSetPrincipal - TRUE if you want to add/update the principal's entry *
* in the ACL, FALSE if you want to remove the principal from the ACL *
* *
* fPermit - TRUE if you want to allow the principal to launch the object *
* FALSE if you want to prevent the principal from launching the object *
* *
* dwAccessMask - Specifies what type of access the principal is to be *
* given. Can be any combination of the COM_RIGHTS_* values *
* *
* --------------------------------------------------------------------------*
* RETURNS: WIN32 Error Code *
