Note This function signature is shown as it appears when you create a client using the LabWindows/CVI ActiveX Controller Wizard. If you create a client for the LabWindows/CVI ActiveX server interface using a different development environment, this function might be exposed differently. Some of the parameters documented here, such as objectHandle or errorInfo, are not applicable if you write a client using a different development environment. |
Purpose

All of the methods that you can apply to a particular object are grouped under a single class in the function tree. The name of the class corresponds to the type of the object to which this handle refers. |

When an ActiveX server function fails with the error codes DISP_E_PARAMNOTFOUND, DISP_E_TYPEMISMATCH, or E_INVALIDARG, the parameter position of the invalid argument may be stored in the errorParamPos member of this parameter. You can pass NULL for this parameter. |
| returnValue | long * | The value that the LabWindows/CVI ActiveX server function returns. A negative value indicates that the LabWindows/CVI ActiveX server function returned an error.
