Good, since the introduction of the PlusWnd::RegisterMessageNotification function I saw this as the solution to my child windows resizing problem. And yes, it was. By registering WM_SIZE and WM_SIZING for my main window I don't need a timer anymore to refresh the size.

However, I still have a timer for my window. This timer is used to update the preview which shows how the countdown will look like. RegisterMessageNotification works for PlusWnd objects, but how can I make it work for a control? So, for example, when the date of a DateTimeControl is changed (DTN_DATETIMECHANGE), it should trigger a function.

Not possible, it is only for Plus! Windows.

So, there's no way to do this?

Then I better keep my timer.

A message should be sent to the parent window when it's changed, or at least a click message -- you can register that too.
