Метод Описание
RegisterForUsbEvents ( IntPtr hWnd, System.Guid gClass ) : IntPtr

Registers a window to receive windows messages when a device is inserted/removed. Need to call this from a form when its handle has been created, not in the form constructor. Use form's OnHandleCreated override.
UnregisterForUsbEvents ( IntPtr hHandle ) : bool

Unregisters notifications. Can be used in form dispose

Описание методов

RegisterForUsbEvents() публичный статический Метод

Registers a window to receive windows messages when a device is inserted/removed. Need to call this from a form when its handle has been created, not in the form constructor. Use form's OnHandleCreated override.
public static RegisterForUsbEvents ( IntPtr hWnd, System.Guid gClass ) : IntPtr
hWnd System.IntPtr Handle to window that will receive messages
gClass System.Guid Class of devices to get messages for
Результат System.IntPtr

UnregisterForUsbEvents() публичный статический Метод

Unregisters notifications. Can be used in form dispose
public static UnregisterForUsbEvents ( IntPtr hHandle ) : bool
hHandle System.IntPtr Handle returned from RegisterForUSBEvents
Результат bool

Описание свойств

InvalidHandleValue защищенное статическое свойство

Simple representation of the handle returned when CreateFile fails.
protected static IntPtr,System InvalidHandleValue
Результат System.IntPtr

NullHandle публичное статическое свойство

Simple representation of a null handle : a closed stream will get this handle. Note it is public for comparison by higher level classes.
public static IntPtr,System NullHandle
Результат System.IntPtr
