The IRichEditOleCallback interface is used by a rich text edit control to retrieve OLE-related information from its client. A rich edit control client is responsible for implementing this interface and assigning it to the control by using the EM_SETOLECALLBACK message.
Inheritance
The IRichEditOleCallback interface inherits from the IUnknown interface. IRichEditOleCallback also has these types of members:
Methods
The IRichEditOleCallback interface has these methods.
| IRichEditOleCallback::ContextSensitiveHelp Indicates if the application should transition into or out of context-sensitive help mode. This method should implement the functionality described for IOleWindow::ContextSensitiveHelp. |

| IRichEditOleCallback::QueryAcceptData During a paste operation or a drag event, determines if the data that is pasted or dragged should be accepted. |
