The indentation's wrong. The line starting "for subkey in..."
should be indented to the same level as the line above, placing
it within context of the "with open (...):" from a few lines
above. I've just checked the email I sent with that in, and it
looks ok (on my email client) so I can only imagine that
one of the various email clients / servers between us has
munged the indentation.

[python-win32] (no subject)
Hello!
Can anyone give me some hint please? I'm trying to make a log file which keep
track of a specific application. For example, I need to punch the time et date
where an application, such as Firefox, is opened and when it's closed. I also
need to detect when the application goes to idle and when it's re-activate
again. (I hope my question it's clear enough.) Thank you!

Re: [python-win32] Win API call to display a BMP/PNG file as a splash screen for a console app?
Malcolm: I used to have exactly what you need. Unfortunately, when I checked just now, I find that I failed to "lift" a copy of the source code when I left the place where I wrote it. "It" was a command line utility which accepted as arguments the name of a .jpg file and the number of seconds to display it before exiting. As it happens, mine was written in wxPython. Any of the previous suggestions would be a good start. The point is that you have your console program run the splash as a separate (non-console) program -- using a "Run and don't wait" OS call -- so that the GUI stuff is not complicating your console code. My application displayed a cartoon of a human skeleton looking at a computer display which said "Please Wait." It was placed at the beginning of a long and complicated automatic login script for a dedicated workstation and displayed for 20 seconds. It completely eliminated anxious users trying to poke at the workstation before it was ready. Yes, the extra .exe and the .jpg will add a little weight to your distribution, but storage is cheap these days, and user satisfaction is worth it, IMHO. -- Vernon > > On 1:59 PM, pyt...@bdurham.com wrote: > > Is there a Windows API call I can use to display a BMP or a PNG file in a > window centered on a user's display?

Yes, you need to find the window handle of your dialog. You can use the FindWindow API to do that. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

You don't NEED this second call. The number you get from the first call
is the handle to the dialog. Just pass that to SetDlgItemText along
with the control ID (1).
The reason is fails is that FindWindow only returns top-level windows,
not child windows. It IS possible to use FindWindowEx to search child
windows, but you don't want that. What you NEED is the top-level dialog
(which you have) and the control ID (which you also have).

You need to install a "window hook" to intercept the activate and deactivate messages going to all of the top-level windows in the system. The reason it's complicated is because of the way window hooks work. Your code must live in a DLL, and that DLL is injected into every process in the system. Thus, such a thing cannot be written in Python. You could certainly have a simple hook DLL that reports statistics back to some Python server "mother ship". There are several web articles on writing window hooks. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

On Linux, I think you could do that rather easily. On Windows, the sentence "just monitor the process ids" is not as trivial as it sounds. It's possible to use ToolHelp to run through the list of processes, and the list of threads for those processes, then use GetThreadTimes to get the CPU time. That doesn't necessarily tell you when an application gains and loses focus. It all depends on what the OP really needs to know. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

It shouldn't be any more complicated than that. I was under the impression that SetDlgItemText marshaled the string pointer so it would work between processes, but perhaps I am mistaken. SetDlgItemInt should CERTAINLY work -- perhaps you should try that first. BTW, you don't need to use ctypes for this. FindWindow, SetDlgItemText and SetDlgItemInt are all exported from win32gui. import win32gui t = win32gui.FindWindow( None, "Windows App" ) win32gui.SetDlgItemInt( t, 1, 37 ) -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
