OLECMDEXECOPT_SHOWHELP = 3
对于这个参数﹐一般来说﹐选1就可以了。4.常用:
WebBrowser.ExecWB(1,1) 打开
WebBrowser.ExecWB(2,1) 关闭现在所有的IE窗口，并打开一个新窗口
WebBrowser.ExecWB(4,1) 保存网页
WebBrowser.ExecWB(6,1) 打印
WebBrowser.ExecWB(7,1) 打印预览
WebBrowser.ExecWB(8,1) 打印页面设置
WebBrowser.ExecWB(10,1) 查看页面属性
WebBrowser.ExecWB(15,1) 好像是撤销，有待确认
WebBrowser.ExecWB(17,1) 全选
WebBrowser.ExecWB(22,1) 刷新
WebBrowser.ExecWB(45,1) 关闭窗体无提示5.示例﹕
