运用VC或对Office进行编程操作的方法技巧
用VC对Office进行操作的介绍已经不少了，但是从来没有把word,excel,powerPoint进进全面的介绍的。
由于工作的需要，我需要对在自己的软件中对word,excel,powerPoint进行操作。所以把自己的体会写出来和大家分享，希望对大家有所帮助。当然还有很多不当之处，希望大家指出。
用例子来说明吧，首先创建一个MFC AppWizard(EXE)工程，然后通过在VIEW菜单中，选ClassWizard,选Automation选项卡,选Add Class,选择From a TypeLibrary, 选中MicrosoftOffice 2000 类型库:Excel9.olb，MSPPT9.OLB，MSWORD9.OLB(在Microsoft Office/Office目录下) 会将类型库中的所有类添加到你的工程中。
然后写一个类来操作Office吧!

以上是用Office打开相应的文档进行打印的操作，如果你需要进行相应的其他操作，你可以用Office里面的宏进行录制然后转化为相应的代码。
对于在Java里需要时行Office操作的，你必须用JNI调用或运用Java-Com的相应包
