据说是最后一个支持VC6R的SDK，我在项目中出现如下错误： error LNK2001: unresolved external symbol _CLSID_ ConnectionManager 明明包含了这些头文件，也链接了LIB。。。 #include //启用、禁用网卡 #pragma comment(lib,"ole32.lib")
VC6使用WMI编程时，最好更新一下SDK。 下面给出Microsoft Platform SDK Febrary 2003下载地址： http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.1.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.2.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.3.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.4.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.5.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.6.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.7.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.8.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.9.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.10.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.11.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.12.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.13.cab http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.bat http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/Extract.exe
ps：安装SDK需要IE5或者之后版本的浏览器
下载到同一个目录下，如：D:VC6.0SDK2003 1、进入命令行方式,进入D:VC6.0SDK2003 2、输入PSDK-FULL.bat D:SDK2003 第2步是将文件再解压到D:SDK2003目录下，路径之间不能有空格，目录不存在的情况会自动创建。 3、运行D:SDK2003中的setup.exe来安装SDK。 4、记得点 Windows Install SDK 来安装所有SDK内容。 5、安装成功后，先关闭Microsoft Visual C++ 6.0。 6、到开始菜单--Microsoft Platform SDK February 2003--Visual Studio Registration点击Register PSDK Directories with Visual Studio自动注册SDK的路径到工程设置里面。
