hi,
i have a problem with undo. i load a dxf/dwg-file, call startundorecording(); and then i change the color of some entities.
when i make undo (), i get the message "undo-operation is not available".
i don't now why this happend...

you class derived from oddbhostappservices must implement function newundocontroller() to enable undo functionality.
see odamfcapp sample: odamfcappapp::newundocontroller() returns an object implementing undo controller interface.
its sample implementaion is in examples/exservices folder.
