From: Alex Hall on 9 Mar 2010 08:55 Hi all, In the same program I wrote about yesterday, I have a dictionary of keystrokes which are captured. I just tried adding a new one, bringing the total to 11. Here are entries 10 and 11; 10 has been working fine for months. 10 : (57, win32con.MOD_CONTROL), 11 : (99, win32con.MOD_CONTROL | win32con.MOD_SHIFT) Now, though, when I press ctrl-shift-c (keystroke 11), nothing happens. Pressing any other keystroke after that will crash the program with some sort of Python internal com server exception that I have never seen before. When set to a keystroke I already use, such as #10, the function called by #11 works just fine. Does anyone see a problem with the above syntax? The trouble almost definitely has to be there; again, using an already-working keystroke instead of making a new one works perfectly, it is just when I add this new one that things break. -- Have a great day, Alex (msg sent from GMail website) mehgcap(a)gmail.com; http://www.facebook.com/mehgcap

Neither do I, in particular since you don't share that rare gem with us. ;) Uli -- Sator Laser GmbH Geschäftsführer: Thorsten Föcking, Amtsgericht Hamburg HR B62 932
From: Alex Hall on 9 Mar 2010 11:18 I know ctrl-c kills a process in the shell, but these are global hotkeys and all others work fine. You made me discover something, though: the error only happens if ctrl-shift-c is pressed when in the shell from where the program was run; when pressed anywhere else, the keystroke does nothing at all. Is there something I am missing about these keystroke dictionaries? It seems like they do not work unless the keycodes are in numerical order and are not separated by more than one number. Currently, my dictionary consists of the numbers 1-0 on the top of the keyboard, but adding any other keycode, like the 99 in my original message, will cause that keystroke to do absolutely nothing. Thanks to your response, I suspect the problem is something to do with the keypress being captured by the shell. Still, not being able to use anything except numbers is very annoying!! Why would this be happening?

You may be able to do something by adding a break handler through SetConsoleCtrlHandler (exposed in win32api). But it would obviously be a special case outside your normal control flow. TJG

But that would only work (I think) in one console, not at a global level. TJG |
