有没有代码可以实现对本PC机浏览器的记录进行清空

[小赵儿]

我写了一个mfc，里面要加载一张地图，实现了。但是有个小问题，地图是用html写的，要连接浏览器，可能在之前连接的时候，由于网络或者其他原因，虽然地图加载上了，但是网络不好，卡住了，然后看的就跟没加载上一样，要清空一下浏览器，就好了。我想用代码实现对浏览器的清空，不知道那位大哥有高见，请赐教，谢谢！！！！！！！！！！！！！！！

刷新不就全部重新加载了吗

[小赵儿]

地图之前已经加载上了，再次加载的时候就直接调用之前加载好的，所以还是看不到，刷新没用。只有将之前的删掉，重新再去加载一遍。

重绘窗口呢？

报了这么多的错，主要是那几个库函数没定义，需要包含什么头文件吗？

这个是从网上找到的代码，不过好多的错，谁能帮忙改改，谢谢
