Methods
Name
Description
Indicates whether the data object contains data in the WaveAudio format. (Inherited from DataObject.)
Indicates whether the data object contains data that is in the FileDrop format or can be converted to that format. (Inherited from DataObject.)
Indicates whether the data object contains data that is in the Bitmap format or can be converted to that format. (Inherited from DataObject.)
Overloaded. Indicates whether the data object contains text data.
Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
.gif "Protected method")
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Retrieves an audio stream from the data object. (Inherited from DataObject.)
Overloaded. Returns the data associated with the specified data format.
Overloaded. Determines whether data stored in this DataObject is associated with the specified format.
Retrieves a collection of file names from the data object. (Inherited from DataObject.)
Overloaded. Returns a list of all formats that data stored in this DataObject is associated with or can be converted to.
Serves as a hash function for a particular type. (Inherited from Object.)
Retrieves an image from the data object. (Inherited from DataObject.)
Overloaded. Retrieves text data from the data object.
Gets the type of the current instance. (Inherited from Object.)
Creates a shallow copy of the current Object. (Inherited from Object.)
Overloaded. Adds data to the data object in the WaveAudio format.
Overloaded. Adds an object to the DataObject.
Adds a collection of file names to the data object in the FileDrop format. (Inherited from DataObject.)
Adds an Image to the data object in the Bitmap format. (Inherited from DataObject.)
Overloaded. Adds text data to the data object.
Returns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations
Name
Description
.gif "Explicit interface implemetation")
.gif "Private method")
Infrastructure. Creates a connection between a data object and an advisory sink. This method is called by an object that supports an advisory sink and enables the advisory sink to be notified of changes in the object's data. (Inherited from DataObject.)
Establishes a connection between the data object and a caller object implementing IAdviseSink.
Infrastructure. Destroys a notification connection that had been previously established. (Inherited from DataObject.)
Terminates an advise connection previously established through DAdvise(FORMATETC, UInt32, IAdviseSink, UInt32).
Infrastructure. Creates an object that can be used to enumerate the current advisory connections. (Inherited from DataObject.)
Creates an enumerator to iterate through the current advisory connections.
Infrastructure. Creates an object for enumerating the FORMATETC structures for a data object. These structures are used in calls to GetData or SetData. (Inherited from DataObject.)
Creates an enumerator to iterate through the FORMATETC structures supported by the data object.
IDataObject.GetCanonicalFormatEtc
Infrastructure. Provides a standard FORMATETC structure that is logically equivalent to a more complex structure. Use this method to determine whether two different FORMATETC structures would return the same data, removing the need for duplicate rendering. (Inherited from DataObject.)
IDataObject.GetCanonicalFormatEtc
Retrieves a FORMATETC structure that is logically equivalent to one that is more complex.
Infrastructure. Obtains data from a source data object. The GetData method, which is called by a data consumer, renders the data described in the specified FORMATETC structure and transfers it through the specified STGMEDIUM structure. The caller then assumes responsibility for releasing the STGMEDIUM structure. (Inherited from DataObject.)
Transfers data from the data object to the client. The pformatetcIn parameter must specify a storage medium type of TYMED_MFPICT.
Infrastructure. Obtains data from a source data object. This method, which is called by a data consumer, differs from the GetData method in that the caller must allocate and free the specified storage medium. (Inherited from DataObject.)
Similar to GetData(FORMATETC, STGMEDIUM), except the client must allocate the STGMEDIUM structure.
Infrastructure. Determines whether the data object is capable of rendering the data described in the FORMATETC structure. Objects attempting a paste or drop operation can call this method before calling GetData to get an indication of whether the operation may be successful. (Inherited from DataObject.)
Determines whether the data object supports a particular FORMATETC structure for transferring data.
Infrastructure. Transfers data to the object that implements this method. This method is called by an object that contains a data source. (Inherited from DataObject.)
Transfers data from the client to the data object.
