有msdn吗？哪里有，如果需要知道函数的用法，载索引里输入snmp然后后面的自己找就可以了。对了，给你一个网址，那里有一个vb的程序，那里面关于snmp的函数的调用的顺序写的很明白。

对了还需要一个lib：wsnmp32.lib。具体的函数的用法参考我给你的网址上的vb的实例。好运！

我在msdm中找过，但发现编译总是不通过。
给出如下的信息
不知道怎么处理

能告诉小弟怎么处理吗
万分感激

Header: Declared in Winsnmp.h.
Library: Use Wsnmp32.lib.have you include this header file?

他是链接错误，肯定是没有加上lib。

怎么加那个库啊
用include？

add your Wsnmp32.lib to object library modules.
