IDataObject Interface

Definition

Creates a connection between a caller and a data object implementing the IDataObject interface. This connection enables notifications of changes in the data for the data object to the caller.

public interface class IDataObject
[System.Runtime.InteropServices.Guid("0000010e-0000-0000-C000-000000000046")]
[System.Runtime.InteropServices.InterfaceType(System.Runtime.InteropServices.ComInterfaceType.InterfaceIsIUnknown)]
public interface IDataObject
[<System.Runtime.InteropServices.Guid("0000010e-0000-0000-C000-000000000046")>]
[<System.Runtime.InteropServices.InterfaceType(System.Runtime.InteropServices.ComInterfaceType.InterfaceIsIUnknown)>]
type IDataObject = interface

Methods

DAdvise(IntPtr, Int32, IntPtr, Int32)

Creates a notification connection between a data object implementing the IDataObject interface and a caller object, letting the caller receive notification of changes in the data for the data object.

DUnadvise(Int32)

Destroys a notification connection that was created by an earlier call to the DAdvise(IntPtr, Int32, IntPtr, Int32) method.

EnumDAdvise(IntPtr)

Retrieves a pointer to an object that can enumerate the notification connections that are currently maintained by this IDataObject interface.

EnumFormatEtc(Int32, IntPtr)

Retrieves a pointer to an object that can enumerate the FORMATETC enumerator types that this implementation supports.

GetCanonicalFormatEtc(IntPtr, IntPtr)

Retrieves a pointer to a standard FORMATETC structure that is logically equivalent to, but not necessarily equal to, the FORMATETC structure that is referenced by the a parameter.

GetData(FORMATETC, STGMEDIUM)

Renders the data that is described in the specified pFormatEtc structure and transfers it to the b parameter.

GetDataHere(FORMATETC, STGMEDIUM)

Renders the data that is described in the specified pFormatEtc structure and transfers it to the b parameter.

QueryGetData(FORMATETC)

Retrieves a value indicating whether the implementer can render the data that is contained in the a parameter.

SetData(IntPtr, IntPtr, Int32)

Transfers the data that is contained in the STGMEDIUM structure, referenced by a, to this instance of the IDataObject interface.
