Indicates that the specified cells are about to change. aboutToChangeCell is an event handler method, implemented through OLEDBSimpleProvider::addOLEDBSimpleProviderListener. This notification is issued when values are modified through OLEDBSimpleProvider::setVariant or internally through a provider, and before any data value changes are implemented.
Important
This feature will be removed in a future version of Windows. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Instead, write a fully functional OLE DB provider using the native OLE DB interfaces.
