RTD(progID, server, topic1 [,topic2] [,…]) |
| Returns the real time data from a program that supports COM automation. |
| progID | The programmatic ID of the registered COM add-in. | |
| server | The name of the server running the add-in. | |
| topic1 | The first parameter to pass to the add-in. | |
| topic2 | The second optional parameter to pass to the add-in. |
| REMARKS |
| The RTD COM automation add-in must be installed and registered on the computer. | ||
| No RTD servers are shipped with Microsoft Office, so you must manually install a real-time data server if you want to use this function. | ||
| The "progID" must be enclosed in speech marks. | ||
| The "server" must be enclosed in speech marks. | ||
| If the real-time data server is being run locally then leave the "server" argument blank. | ||
| This function will only continuously update when the calculation mode is set to automatic. | ||
| When using RTD within Visual Basic for Applications (VBA), double quotation marks or the VBA NullString property are required for the server, even if the server is running locally. | ||
| You can have a maximum of 28 topics. | ||
| This function was added in Excel 2002. |
