BSCF enumeration

Values from the BSCF enumeration are passed to the client in IBindStatusCallback::OnDataAvailable to indicate the type of data that is available.

Syntax

typedef enum  { 
  BSCF_FIRSTDATANOTIFICATION         = 0x00000001,
  BSCF_INTERMEDIATEDATANOTIFICATION  = 0x00000002,
  BSCF_LASTDATANOTIFICATION          = 0x00000004,
  BSCF_DATAFULLYAVAILABLE            = 0x00000008,
  BSCF_AVAILABLEDATASIZEUNKNOWN      = 0x00000010,
  BSCF_SKIPDRAINDATAFORFILEURLS      = 0x00000020,
  BSCF_64BITLENGTHDOWNLOAD           = 0x00000040
} BSCF;

Constants

• BSCF_FIRSTDATANOTIFICATION
  Identify the first call to IBindStatusCallback::OnDataAvailable for a given bind operation.

• BSCF_INTERMEDIATEDATANOTIFICATION
  Identify an intermediate call to IBindStatusCallback::OnDataAvailable for a bind operation.

• BSCF_LASTDATANOTIFICATION
  Identify the last call to IBindStatusCallback::OnDataAvailable for a bind operation.

• BSCF_DATAFULLYAVAILABLE
  All of the requested data is available.

• BSCF_AVAILABLEDATASIZEUNKNOWN
  Size of the data available is unknown.

• BSCF_SKIPDRAINDATAFORFILEURLS
  Internet Explorer 8. Flag sent to IBindStatusCallback::OnDataAvailable to bypass cache downloads for file:// URLs. Normally, the cache file is emptied when new data is available. Specify this flag when it is not necessary to read the data and throw it away, such as when downloading a file through a UNC path.

• BSCF_64BITLENGTHDOWNLOAD
  Internet Explorer 8. Notification to the IInternetProtocolSink::ReportProgress that the size cannot be expressed in 32-bit terms for downloads exceeding 4 GB.
