The TCnPing type exposes the following members.
| Name | Description | |
|---|---|---|
 | Create(TComponent) | Creates and initializes a TCnPing instance. (Overrides TClrBaseComponent.Create(TComponent).) |
| Destroy | Frees the resources allocated with a TCnPing instance. (Overrides TClrBaseComponent.Destroy.) |
