[vtkusers] MFC CWnd and VTK

[Andrew J. P. Maclean]

The leaks may be a MFC "feature"! Often many of these problems go away
if you statically link in the MFC DLL's. If it only occurs on exit it
may be due to the fact that (I think!) that the MFC dynamic DLL's don't
clean up properly on exit.

Thanks for your kind comments (and many thanks to John for all the work
he did). I deliberately designed these demos to be as simple as possible
(with reasonable functionality) in order to let new users get started
quickly.

Hello All,

These demos work for me, I still get one memory leak using the vtkSDI
example but that's a blessing considering the hundreds in the original
demos.

I have tracked down this memory address before and the problem seems to
be
in the vtkOpenGLPolyDataMapper.cxx class. I found the threads in the
mail
archives relating to this earlier and moved the vtk classes and
destructors
from the doc to the view but it didn't help.

...
Detected memory leaks!
Dumping objects ->
{2216} normal block at 0x03787320, 5200 bytes long.
 Data: <        Building> 00 00 00 00 00 00 00 00 42 75 69 6C 64 69 6E
67
Object dump complete.
...

I must confess to having written some huge commercial apps using MFC,
I'll
add some complexity to these demos (sliders/buttons/splitters/doc
archives)
when I get a chance and send them to John.

Thanks again Andrew,

Tom
