| Name | Type | Description |
| panelHandle | int | Specifier for a particular panel that is currently in memory. You can obtain this handle from functions such as LoadPanel and NewPanel. |
| controlID | int | The defined constant, located in the .uir header file, that you assigned to the control in the User Interface Editor, or the ID returned by functions such as NewCtrl and DuplicateCtrl. |

You can create a Point without having to declare a variable by using the following function: Point MakePoint (int x, int y); ExampleGetTableCellRingValueFromIndex (panelHandle, controlID, MakePoint (2, 3), 0, buffer); |
| index | int | The zero-based index into the list of values. |
