Hello:
Please forgive me if my question is too silly or just not
well-formed.
Wesley Chun in his book (Core Python Programming) says that
**everything** in Python is an object. So I became curious
about the precise definition of an object in Python. My
curiosity was also driven by Wesley's statement that while
every class instance is...

Has anyone come across this exception before when dealing with C#
graphics? Have come across some answers that point to the
accelleration control under the screen's
properties/settings/advanced/troubleshooting.

Hi,
I've started work on my own control some parts of which use standard
controls, others I need to draw on my controls surface to get the display
output I require, however....
I seem to be stupid or missing the point. I used DrawString( ) as a simple
test but I cannot get it to work at all unless I handle my custom controls

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
