Hi Roel
"Our problem turned out to be caused by a loss of precision in an
application of ours, caused by Direct3D. The solution for us was to
include the flag D3DCREATE_FPU_PRESERVE in CreateDevice(). The
documentation seems to imply that the lower precision only has effect in
the Direct3D code, b
blems and appears to be frozen as a result.
C, only supporting early binding cannot change the function referenced
at runtime so how the devil is it managing to do this.

Hi all,
I've been a long time user of Python and written many extensions but
this problem has me stumped.
I've written a straight forward extension that wraps a vendors SDK for a
video capture card. All works well except that in the Python thread on
which I call the extension, after certain calls
Title: RE: built-in 'property'
Thanks to everyone that has helped on this. What I am trying to do is create a capability based api that I can build to order. This is as far as I get at the moment.
Each of the first three classes represents some function I can do to a radio, there would be man
Title: RE: built-in 'property'
What I want to achieve is a class whereby I can set the property access per instance so the user can test if a property is present using hasattr(klass,'prop') such that the instance has a given capability that can easily be tested by the user. The actual get/set
it is a property object. Is this statement only designed to
work at class scope? I really want to set these properties per
instance.
Thanks

Yes I am realising there are variaous ways to achieve the same end. I guess I am in research mode at the moment and understanding what metaclasses can do is important even if I end up not using them. There is another thread on this question where I am trying to

only way I can see to
do this at the moment is to have a metaclass for each capability type and
hardcode the type inside it, then pick the appropriate metaclass when I build
the implementation class.
