Answer 1

如果不用UPDATE_COMMAN_UI的话:
CToolBar* pBar = &m_wndToolBar;
UINT iButtonID;
UINT iButtonStyle; 
int  iButtonImage;
pBar->GetButtonInfo(3, iButtonID, iButtonStyle,iButtonImage);
iButtonStyle = 0;
pBar->SetButtonInfo(3, iButtonID, iButtonStyle,iButtonImage);
如果想用UPDATE_COMMAN_UI:

重载CToolBar, 处理WM_IDLEUPDATECMDUI
LRESULT CToolBarEx::OnIdleUpdateCmdUI(WPARAM wParam, LPARAM) 
{
CToolBar::OnIdleUpdateCmdUI(wParam, 0);  if (IsWindowVisible()) 
{
CFrameWnd *pParent = (CFrameWnd *)GetParent();
if (pParent)
OnUpdateCmdUI(pParent, (BOOL)wParam);
}
return 0L;
}再Dialog中处理ON_MESSAGE_VOID(WM_KICKIDLE, OnKickIdle)void CMyDlg::OnKickIdle()
{
SendMessageToDescendants( WM_IDLEUPDATECMDUI );
}然后UPDATE_COMMAN_UI就可用了，哈哈
