CButton - change background color problem
You don't need to override every single control, there are always some
walkarounds. For instance, you could trap WM_LBUTTONDOWN in
PreTranslateMessage, you could avoid subclassing controls with MFC classes
and use GetDlgItem instead etc.
I don't think it's am only root of all UI bugs, there are other bugs for
this. ;)
As to service pack, this is not possible since MFC library (release version
of it) is part of Pocket PC platform and is supplied with all devices (in
device ROM). So patching eVC will not help at all. As to fixing this bug in
future versions of MFC, I doubt that this will happen. The bug we are
discussing may in fact be a feature. ;-)
