VC对Office进行操作

注：本文转载于vctop.com，如有问题，请与站长联系。

 

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Microsoft Office 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。

例2:

给企业开发的项目中，客户经常要求将数据汇总显示并打印。站在程序员的立场上，简单数据的汇总打印可以采用VB自带报表，对复杂的数据用水晶报表或第三方打印控件。在企业中，汇总数据另一个目的是为了便于交流和共享资源，报表的格式通常固定，内容可以自己调整，他们对 Excel 和 Word 情有独钟。

　　刚完成的项目中，客户要求将汇总的数据以三种方式进行显示和打印：AutoCad、Excel 和 Word 文档中。前两种方式网上资源很多，对 Word 文档我找到例子不是很多。由于需要和 AutoCad 开发程序结合，不能将 Word 文档以 OLE 的方式 嵌入到程序中，文档只能在内存中形成，这将占用大量的CPU资源，另开一个线程进行处理，线程间以发送消息的方式进行通信。

　　首先在VC引入Word, 对格式相同的地方一定使用模版的方式进行处理，这可以大大的提高运行速度,Word中的模版为*.dot。加载模版的代码为：

sDocs=sApp.GetDocuments();
　　 sDocs.AttachDispatch(sApp.GetDocuments(),true);
　　 COleVariant vFalse((long)0),vTrue((long)1);
　　 sDoc.AttachDispatch(sDocs.Add(COleVariant(_variant_t(strFileName)), vFalse,vFalse, vTrue));

　　需要注意的是，如果Word中使用到表格，VBA录制的全是Selection对象的处理方法，在VC中使用Selection对象的MoveUp和MoveDown函数时会出现不确定现象（如果你知道为什么的话请告诉我）。如果你需要绘制表格，不要用程序来动态形成，绘制表格的代码是很繁琐的，而且在页眉中绘制单元格是很难控制的。可以先在模版中绘出你要的表格格式，然后用程序复制单元格或者直接使用模版中的单元格。由于我做的项目表格的行数不确定，我采用的是复制单元格的方式（速度比较慢，谁有更好的方法?）。

　　剩下的处理流程，就是你想做什么操作，先在Word中录制一段宏，然后查看其VBA代码，并将其转化到Vc程序中。这就看你Word使用的熟练程度了，例如如何把不同页的页眉页脚设置不同，如何得到当前页的页数以及总的文档的页数，具体可以参考程序。

　　VC中也可以像Excel中调用模版中存在的宏，代码如下：

VARIANT vtMissing ;vtMissing.vt =VT_ERROR;
　　 vtMissing.scode =DISP_E_PARAMNOTFOUND;
　　 sApp.Run("AddCell",&vtMissing,&vtMissing,&vtMissing,
　　 &vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing,
　　 &vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing,
　　 &vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing,
　　 &vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing,&vtMissing);
