Pyhook stops capturing key events after 6 clicks

Question

I wrote a script to move the mouse when a key is pressed using pyHook. The problem is that after 6 keystroke events, the script stops typing keystrokes and needs to be terminated from the task manager.

I am using python 2.7 on a Windows 7 machine. I have not found anyone else with an answer to a similar problem.

The code is designed to connect the mouse, and then when it is clicked, move the cursor, unhook the mouse and hook the keyboard. There the keyboard hook only works for 6 events. If I hold both the mouse and the keyboard, each hook only works for 6 events. Does anyone have any idea what the problem is and how to fix it?

import pythoncom, pyHook, win32api import math from time import sleep # Radius is 250px radius = 50 # Intervals in the circle n_intervals = 50 # List of intervals l_intervals = [] for i in range(0, n_intervals): l_intervals.append((i+1) * math.pi * 2 / n_intervals) # Move the cursor in a circle def move_circle(): (x, y) = win32api.GetCursorPos() old_pos = (x, y) center = (x-radius, y) for i in l_intervals: p = (radius * math.cos(i), radius * math.sin(i)) new_pos = (int(center[0]+p[0]), int(center[1]-p[1])) win32api.SetCursorPos(new_pos) sleep(0.01) def OnKeyboardEvent(event): if event.Key == "Media_Play_Pause": exit() else: move_circle() # return True to pass the event to other handlers return True def OnMouseEvent(event): # called when mouse events are received if event.MessageName == "mouse left down": move_circle() # move the cursor hm.UnhookMouse() # unhook the mouse hm.HookKeyboard() # hook the keyboard return True hm = pyHook.HookManager() hm.MouseAll = OnMouseEvent hm.KeyDown = OnKeyboardEvent # Hook the mouse hm.HookMouse() # Wait for any events pythoncom.PumpMessages() 

UPDATE: I found a solution and posted the answer below, but I will still be grateful for any answers that may explain why I had the problem in the first place and why the solution corrects it.

Answer 1

After another google search, I found a solution that worked for me: pyHook + pythoncom stopped working after too much keystroke [Python] . I tried my first suggestion and my problem was resolved. Now my piece of pyHook code looks like this:

 import pythoncom, pyHook, win32api, sys import math import threading, time from time import sleep ... #attempt to stop pyHook hang... lock = threading.Lock() def KeyEventThread1(i): lock.acquire() sys.exit() lock.release() def KeyEventThread2(i): lock.acquire() move_circle() lock.release() def OnKeyboardEvent(event): if event.Key == "Media_Play_Pause": t = threading.Thread(target=KeyEventThread1, args=(1,)) t.start() sys.exit() else: t = threading.Thread(target=KeyEventThread2, args=(1,)) t.start() # return True to pass the event to other handlers return True def MouseEventThread(i): lock.acquire() sleep(.2) #So that mouse is not depressed when moved move_circle() # move the cursor hm.UnhookMouse() # unhook the mouse lock.release() def OnMouseEvent(event): # called when mouse events are received if event.MessageName == "mouse left down": t = threading.Thread(target=MouseEventThread, args=(1,)) t.start() hm.HookKeyboard() return True hm = pyHook.HookManager() hm.MouseAll = OnMouseEvent hm.KeyDown = OnKeyboardEvent # Hook the mouse hm.HookMouse() # hook the keyboard # Wait for any events pythoncom.PumpMessages()
