From what you have provided YES, OnTimer could get called before
OnSomeMessage.

Now it's not clear how OnSomeMessage gets called.

And OnTimer wouldn't get called until OnSomeMessage returns.

Could parent window's handler be called while a child window is being
resized/moved as a result of a call to MoveWindow() or ShowWindow()?

Let's say that I have the following code:

CParentWnd::OnTimer()
{
}

CParentWnd::OnSomeMessage()
{
m_childWnd.MoveWindow()
m_childWnd.ShowWindow()
}

Both windows are created on the same UI thread. MoveWindow() will result
in WM_SIZE message(s) being sent to the child window. Is there a
possibility that at the same time any pending timer messages for the
parent window will be flushed and as a result parent's OnTimer() handler
will be called before OnSomeMessage() handler completes?

Thanks,
Bogdan
