Re: Problems with wxPython _core_.pyd on windows98

I have a build for Python 2.7 for Windows98 that works but I'm having trouble with running wxPython. I get the following error. I'm sure you have your reasons, but of course Windows 98 hasn't been supported, by Python, Microsoft, or anybody else, for many years. Are you sure it wouldn't be easier to use a newer laptop or install Linux? Support for Windows 98 was dropped in Python 2.6. C:\pyobd>python pyobd.py Traceback (most recent call last): File "pyobd.py", line 28, in import wx File "C:\Python27\lib\site-packages\wx-3.0-msw\wx\__init__.py", line 45, in from wx_core import * File "C:\Python27\lib\site-packages\wx-3.0-msw\wx\_core.py", line4, in import _core_ Import Error: DLL load failed: A device attached to the system is not functioning. So what is going on? Do these pyd files need to be compiled specifically for win98? If so how do I do that? Does python compile these dlls or do I need a C compiler? If you want to compile extension modules, you need to C compiler Python was compiled with. I expect this is Visual C++ 6.0 for the last Win9x releases. Is there an old version of wxPython that will work on windows 98? -- https://mail.python.org/mailman/listinfo/python-list
Re: image in db to string to actual image
And what is your database? Maybe there is an API for the blob field On 08/02, Abdur-Rahmaan Janhangeer wrote: storing images in db is easy but to retrieve them natively how to?

Re: asyncio: Warning message when waiting for an Event set by AbstractLoop.add_reader
Thanks for the answer, but the problem is that this is happening in the built-in Event of the asyncio package; which is actually a coroutine. I don't expect the built-in to have this kind of behavior. I guess I'll have to dig on the source code of the asyncio default loop to actually understand how all the thing is behaving in the shadows. Maybe I'm simply doing something wrong. But it would mean that the documentation is lacking some details, or maybe that I'm just really stupid on this one.
