VS2008 VC+ XML 操作1. msxmlchs.msi 的安装安装 msxml 4.0 sp2 时要注意不要用默认安装,要选择自定义安装（全部安装）才能选择安装 SDK,若没有选择安装 SDk 会发现安装完成后安装目录下什么也没有,而选择了 SDK的安装可以在目录下看到 LIB INC doc 3 个文件夹 2. 注册 dll命令行输入如下命令可以弹出注册成功的对话框cd c:windowssystem32regsvr32 msxml4.dll (也可在运行框中直接输入这句) 3. VS2008 设置工具-选项 -项目和解决方案 -VC+目录 Include 添加 INC 的的路径 C:Program FilesMSXML 4.0INCLibrary 添加 INC 的的路径 C:Program FilesMSXML 4.0LIB4. VC60 设置Tools-Options. -Directories tab-Include 添加 INC 的的路径 C:Program FilesMSXML 4.0INCTools-Options. -Directories tab-Library 添加 INC 的的路径 C:Program FilesMSXML 4.0LIB5. 新建项目，链接库代码中#include VC60 open Project Settings by clicking Settings from the Project menu. Select the Link tab. Append msxml2.lib to the Object/library modules: textbox.6.
