Or windows messages that are outside of the wxWindows world. This is really for capturing custom windows messages Use the standard wxWindows method of binding events for that. This is not the correct way to deal with standard windows messages in wxPython (i.e. You can really screw things up this way, so be careful. WindowProc will not be invoked with the message. If the handler explicitly returns False then the standard Message, the specified handler function is invoked. You supply a set of message handler functions with the function addMsgHandler. This class can be mixed in with any wxWindows window class in order to hook it's WndProc function. _fields_ = [("dbch_size", wintypes.DWORD), _fields_ = [("dbcc_size", ctypes.c_ulong),Ĭlass DEV_BROADCAST_HDR(ctypes.Structure): UnregisterDeviceNotification.argtypes = Ĭlass DEV_BROADCAST_DEVICEINTERFACE(ctypes.Structure): UnregisterDeviceNotification.restype = wintypes.BOOL RegisterDeviceNotification.restype = wintypes.HANDLE WndProcType = ctypes.WINFUNCTYPE(ctypes.c_long, ctypes.c_int, ctypes.c_uint, ctypes.c_int, ctypes.c_int) #WndProcType = ctypes.WINFUNCTYPE(c_int, wintypes.HWND, wintypes.UINT, wintypes.WPARAM, wintypes.LPARAM) # first arg is return type, the rest are the arguments # Create a type that will be used to cast a python callable to a c callback function # It's probably not neccesary to make this distinction, but it never hurts to be safe

There are multiple ways to detect what is happening with device changesĭetecting USB Insertion / Removal Events in Windows using C++ What's wrong with this code? import wmiĭevice_connected_wql = "SELECT * FROM _InstanceCreationEvent WITHIN 2 WHERE TargetInstance ISA \'Win32_Keyboard\'"ĭevice_disconnected_wql = "SELECT * FROM _InstanceDeletionEvent WITHIN 2 WHERE TargetInstance ISA \'Win32_Keyboard\'"Ĭonnected_watcher = c.watch_for(raw_wql=device_connected_wql)ĭisconnected_watcher = c.watch_for(raw_wql=device_disconnected_wql) Issue: No message appears when a USB keyboard is plugged in, but both messages ("Keyboard connected" and "Keyboard disconnected") appear when the USB keyboard is unplugged. The following script is intended to output a message when a USB keyboard is plugged in or unplugged.
REMOVE USB FLASH DRIVE WINDOWS 10 CODE
I've improved the WQL query and Python code based on information I got in MSDN. Is there a way to extend the existing script accordingly? The removal of USB devices is not detected at all. This means that the insertion of USB flash drives is detected, but USB input devices are not. Unfortunately this script does not detect the insertion of all types of USB devices. Raw_wql = "SELECT * FROM _InstanceCreationEvent WITHIN 2 WHERE TargetInstance ISA \'Win32_USBHub\'"
I already have some working Python code to detect the insertion of some USB device types (from here).
