Re: Strange Problem with pythonw.exe
Hello subscribers, I've recently encountered a strange problem with Python for Windows. I'm using Windows 7 Pro 64 Bit and Python 3.2.3 64 Bit (also tried 32 bit). The Problem is, that pythonw.exe does not work at all! Therefore no IDLE for me... But python.exe runs just fine. I ran Process Monitor, which showed some activity for pythonw.exe, but no window is coming up. It is not quite clear what you did here, but if you just run pythonw.exe, you should not see anything, as the 'w' stands for 'Windows', 'windowless', or 'with user interaction through a gui brought up by the python program being run'. It make it hard to debug if no gui is being brought up. The problem isn't restricted to my main python installation. I have also tried running portable python and active state python. No pythonw.exe of them is working. Reinstallation didn't change anything. Windows firewall was deactivated, no difference. No firewall-software or any possibilities of blocking pythonw.exe. I couldn't find the problem online. My problem was triggered by using PyQt. I've loaded an .ui, which did NOT show up. I have Ne ver seen IDLE since that crash. Advice anyone? I take it that IDLE *did* work before using PyQT. If this is correct (I must admit, I hope so), I would ask the author of PyQT whether it or QT does anything to the system that could persist across installs. The most likely change to me would be in the registry. So if it were my machine, I would fire up regedit, back up the registry, search it for 'pythonw', look at the results, and perhaps delete all pythonw entries. Then reinstall the core component. You might also try 3.3.0a4, which had additional bug fixes, or go back to something like 3.2.0. -- Terry Jan Reedy Thank you for your help. I found the problem at some other place. The registry tweaks didn't solve it. But I found the hint to look up my .idlerc folder. So the problem was entirely IDLE related (yes, it worked before). But it wasnt PyQt'S problem, but the mapping of some keyboard command I made. I used the 'ü' key (german keyboard), which kept me from using IDLE for 4 days now... Deleting the %username%/.idlerc folder got the job done finally! Arthur J -- http://mail.python.org/mailman/listinfo/python-list

I believe there is a patch, either on the tracker or applied since 3.2.3, to catch .idlerc problems and report to the user rather than quit. -- Terry Jan Reedy -- http://mail.python.org/mailman/listinfo/python-list

Pythonw.exe appears to work when i run it through cygwin however I don't really want to use cygwin for this application. Any idea as to what might be the problem? Windows GUI programs don't have any standard streams. stdin, stdout and stderr aren't attached so any print statement or traceback isn't shown. Could this explain the behavior?

Thanks in advance, Martin Exactly what program is pythonw executing? You need to search your PATH to see what's on it. For example, if your PATH has a c:\bat directory on it, and in that directory you have a one-line batch file: @c:\python26\pythonw.exe then you're seeing the expected behavior. You'd need to add a parameter to the batch file, probably %* Or you could be pointing at some other executable. The other possibility for you is to use the .pyw file association that your install probably set up for you. Rename your main script to have a .pyw extension, and then just type it as your command. To check file associations, use assoc and ftype utilities, both standard on Windows XP and Vista. DaveA -- http://mail.python.org/mailman/listinfo/python-list
