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
