Description |
| IASProvidePowerListBoxCommandData::GetCaption | Retrieves the caption associated with a particular command item. |
The IASProvidePowerListBoxCommandData interface, which has a global unique identifier equal to IID_ASPROVIDEPOWERLISTBOXCOMMANDDATA, extends the IUnknown interface.
The purpose of this interface is for applications such as Contacts that either have large numbers of entries, or whose entries may change frequently. To use this interface, point to it in the ProvidePowerListBoxCommandData property of the form. The power list box then invokes GetCaption when drawing a command item that has a Null caption.
