ISCardTypeConv interface

[The ISCardTypeConv interface is available for use in the operating systems specified in the Requirements section. It is not available for use in Windows Server 2003 with Service Pack 1 (SP1) and later, Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The Smart Card Modules provide similar functionality.]

The ISCardTypeConv interface provides the methods needed to support the users of the other smart card COM interfaces. This interface is provided for backward compatibility only and should no longer be used.

Members

The ISCardTypeConv interface inherits from the IDispatch interface. ISCardTypeConv also has these types of members:

• Methods

Methods

The ISCardTypeConv interface has these methods.

Method	Description
ConvertByteArrayToByteBuffer	Converts a typical C/C++ byte array into a universal buffer of bytes (IStream object).
ConvertByteBufferToByteArray	Converts a byte array mapped into a universal buffer of bytes (IStream object) into a typical C/C++ byte array.
ConvertByteBufferToSafeArray	Converts a byte array mapped into a universal buffer of bytes (IStream object) into a SAFEARRAY of unsigned char (byte).
ConvertSafeArrayToByteBuffer	Converts a byte array defined as a SAFEARRAY into a universal buffer of bytes (IStream object).
CreateByteArray	Creates an array of bytes.
CreateByteBuffer	Creates a universal buffer of bytes mapped into an IStream (IByteBuffer) object.
CreateSafeArray	Creates an Automation SAFEARRAY of unsigned characters (bytes).
FreeIStreamMemoryPtr	Frees a memory pointer to the HGLOBAL memory block managed by an IStream COM interface.
GetAtIStreamMemory	Acquires a byte pointer to the HGLOBAL memory block that is managed by the IStream COM interface.
SizeOfIStream	Determines the size (number of bytes) of an IStream COM interface.
