TOleContainer and Refresh


Do somebody knows how to refresh a toleContainer object ?
I have a ToleContainer with a Word document inside. For some obscur reasons,
in fact I have made this object as a Active-Form object, the Word window is
not refreshed.

I have tried many methods, the best I have found is to make it not visible
then visible. This works for the text frame but not for the Word toolbar.
I think that I should send a WM-Paint message to the container, I have tried
without success. Is there a solution ?

2nd question: the parent of my active-Form is the calling window ? In this
case can I trap any event sent to this parent window to generate my own
paint method before returning the event to the window (windows hook) ?

Thank for your answers, it's important for my project.
