vc调用dll 其实，调用dll文件的方法很多，不一定要使用LoadLibrary函数。如果使用的话，你就要预先声明dll中的函数，很麻烦-vc call dll in fact, many ways to call the dll files do not have to use the LoadLibrary function. If so, you must pre-declare dll function in much trouble

hinstLib = LoadLibrary("ActPcCom.dll") //装载动态链接库ActPcCom.dll hinstLib1 = LoadLibrary("ActMulti.dll") //装载动态链接库ActPcCom.dll hinstLib2 = LoadLibrary("ActEther.dll") //装载动态链接库ActPcCom.dll
