    ((CMainFrame*)(AfxGetApp()->GetMainWnd()))->ApplyPolicy();
}

void CMainFrame::ApplyPolicy(void)
{
    m_wndToolBar.RemoveButton(4);
    
}

推荐答案

您应该首先为该按钮添加一个测试.如果您的代码被多次调用，则还应该使用按钮标识符而不是索引.您是否真的确定要删除而不是禁用它?

You should first add a test for that button existing. You should also use button identifiers rather than indices in case your code gets called multiple times. Are you really sure that you want this removed rather than disabled?
