CBindStatusCallback Members

IBindStatusCallback Methods

GetBindInfo	Called by the asynchronous moniker to request information on the type of bind to be created.
GetPriority	Called by the asynchronous moniker to get the priority of the bind operation. The ATL implementation returns E_NOTIMPL.
OnLowResource	Called when resources are low. The ATL implementation returns S_OK.
OnObjectAvailable	Called by the asynchronous moniker to pass an object interface pointer to your application. The ATL implementation returns S_OK.
OnProgress	Called to indicate the progress of a data downloading process. The ATL implementation returns S_OK.
OnStartBinding	Called when binding is started.
OnStopBinding	Called when the asynchronous data transfer is stopped.

Class Methods

CBindStatusCallback	The constructor.
~CBindStatusCallback	The destructor.
Download	Starts the download process, creates a CBindStatusCallback object, and calls StartAsyncDownload.
OnDataAvailable	Called to provide data to your application as it becomes available. Reads the data, then calls the function passed to it to use the data.
StartAsyncDownload	Initializes the bytes available and bytes read to zero, creates a push-type stream object from a URL, and calls OnDataAvailable every time data is available.

Data Members

m_dwAvailableToRead	Number of bytes available to read.
m_dwTotalRead	Total number of bytes read.
m_pFunc	Pointer to the function called when data is available.
m_pT	Pointer to the object requesting the asynchronous data transfer.
m_spBindCtx	Pointer to the IBindCtx interface for the current bind operation.
m_spBinding	Pointer to the IBinding interface for the current bind operation.
m_spMoniker	Pointer to the IMoniker interface for the URL to use.
m_spStream	Pointer to the IStream interface for the data transfer.

Static Functions

Download

Creates a CBindStatusCallback object and calls StartAsyncDownload to start downloading data asynchronously from the specified URL.
