Наследование: IDisposable

Private Properties

Свойство	Тип	Описание
BeginAsyncRead	void
GetDevicePath	string
HIDDevice	System
HidD_GetProductString	bool
HidD_GetSerialNumberString	bool
Initialise	void

Метод	Описание
CreateInputReport ( ) : InputReport	Virtual method to create an input report for this device. Override to use.
Dispose ( ) : void	Dispose method
FindDevice ( int nVid, int nPid, Type oType ) : HIDDevice	Finds a device given its PID and VID
RegisterForUsbEvents ( IntPtr hWnd, System.Guid gClass ) : IntPtr
ToString ( ) : string	Converts all significant properties of USBDevice to human readble string
UnregisterForUsbEvents ( IntPtr hHandle ) : bool	Unregisters notifications. Can be used in form dispose

Метод	Описание
Dispose ( bool bDisposing ) : void	Disposer called by both dispose and finalise
HandleDataReceived ( InputReport oInRep ) : void	virtual handler for any action to be taken when data is received. Override to use.
HandleDeviceRemoved ( ) : void	Virtual handler for any action to be taken when a device is removed. Override to use.
ReadCompleted ( IAsyncResult iResult ) : void	Callback for above. Care with this as it will be called on the background thread from the async read
Write ( OutputReport oOutRep ) : void	Write an output report to the device.

Метод	Описание
BeginAsyncRead ( ) : void	Kicks off an asynchronous read which completes when data is read or when the device is disconnected. Uses a callback.
GetDevicePath ( IntPtr hInfoSet, SP_DEVICE_INTERFACE_DATA &oInterface ) : string	Helper method to return the device path given a DeviceInterfaceData structure and an InfoSet handle. Used in 'FindDevice' so check that method out to see how to get an InfoSet handle and a DeviceInterfaceData.
HIDDevice ( uint pid, uint vid ) : System
HidD_GetProductString ( IntPtr hDevice, IntPtr Buffer, uint BufferLength ) : bool
HidD_GetSerialNumberString ( IntPtr hDevice, IntPtr Buffer, uint BufferLength ) : bool
Initialise ( string strPath ) : void	Initialises the device

Virtual method to create an input report for this device. Override to use.

public CreateInputReport ( ) : InputReport

Dispose method

public Dispose ( ) : void
Результат	void

Disposer called by both dispose and finalise

protected Dispose ( bool bDisposing ) : void
bDisposing	bool	True if disposing

Finds a device given its PID and VID

public static FindDevice ( int nVid, int nPid, Type oType ) : HIDDevice

oType	System.Type	Type of device class to create
Результат	HIDDevice

virtual handler for any action to be taken when data is received. Override to use.

protected HandleDataReceived ( InputReport oInRep ) : void
oInRep	InputReport	The input report that was received
Результат	void

Virtual handler for any action to be taken when a device is removed. Override to use.

protected HandleDeviceRemoved ( ) : void
Результат	void

Callback for above. Care with this as it will be called on the background thread from the async read

protected ReadCompleted ( IAsyncResult iResult ) : void
iResult	IAsyncResult	Async result parameter
Результат	void

public static RegisterForUsbEvents ( IntPtr hWnd, System.Guid gClass ) : IntPtr
hWnd	System.IntPtr
gClass	System.Guid
Результат	System.IntPtr

Converts all significant properties of USBDevice to human readble string

public ToString ( ) : string
Результат	string

Unregisters notifications. Can be used in form dispose

public static UnregisterForUsbEvents ( IntPtr hHandle ) : bool
hHandle	System.IntPtr	Handle returned from RegisterForUSBEvents
Результат	bool

Write an output report to the device.

protected Write ( OutputReport oOutRep ) : void
oOutRep	OutputReport	Output report to write
Результат	void
