    <p>A simple program I lifted from somewhere, all it does is register some global keyboard hooks,(for global hotkeys) , It works as expected when the hotkeys() function is called. But if the hotkeys() function is called inside another thread like this:</p> <pre><code>t = threading.Thread(target=hotkeys) t.start() </code></pre> <p>then the statements sys.exit() , os.startfile (os.environ['TEMP']) , user32.PostQuitMessage (0) , inside def handle_win_f3 () are not executed immediately , but after a minute or so(sometimes). Why? and is there a fix? better way of doing what I am doing?</p> <p>The program:</p> <pre><code>import threading import datetime import os import sys import ctypes from ctypes import wintypes import win32con HOTKEYS = { 1 : (win32con.VK_F3, win32con.MOD_WIN), 2 : (win32con.VK_F4, win32con.MOD_WIN) } def handle_win_f3 (): print 'opening' #this works! os.startfile (os.environ['TEMP']) #this doesn't print 'opened' def handle_win_f4 (): print 'exiting' sys.exit() user32.PostQuitMessage (0) HOTKEY_ACTIONS = { 1 : handle_win_f3, 2 : handle_win_f4 } def hotkeys(): byref = ctypes.byref user32 = ctypes.windll.user32 print "hotkeys" for id, (vk, modifiers) in HOTKEYS.items (): print "Registering id", id, "for key", vk if not user32.RegisterHotKey (None, id, modifiers, vk): print "Unable to register id", id msg = wintypes.MSG() while user32.GetMessageA (byref (msg), None, 0, 0) != 0: print 'looping' if msg.message == win32con.WM_HOTKEY: action_to_take = HOTKEY_ACTIONS.get(msg.wParam) print action_to_take if action_to_take: action_to_take () t = threading.Thread(target=hotkeys) t.start() #hotkeys() </code></pre> <p>Thanks</p>

    1. CO`sys.exit()` when run from another thread only kills that thread. What exactly are you trying to achieve? If you want to kill your process entirely, try `os._exit(0)`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
