MFC/VC++调用word进行报表制作

      使用word进行数据报告的制作可谓非常方便,word具有非常强大的编辑、排版功能。使用word能够制作出内容丰富、样式精美的报告。我们在工作中当然会有报表报告的需求,如果能够在MFC/VC++里面能够调用word进行word格式报告的自动生成,岂不是一件非常惬意的事情。

    我在工作当中需要对大量的数据或者各种测试数据进行统计分析,最终的统计分析结果总归要汇总为一份报告,不管是内部使用也好还是外部提供给客户也好,一份内容翔实、格式精美的报告自然必不可少。我对MFC/VC++也不是高手,只是业余爱好自己动动手做些东西。自然,低于VC操作word可谓完全没有经验,在网络上面也查找了很多资料,都是些只言片语,不能真正的领略通过VC使用word的方法。于是自己摸索了几个礼拜,可谓耗时甚长,劳心劳力啊。MS的东西,封装的也太严实了,对于函数部分只有些许的简单介绍,往往看的云里雾里。没有实践还是不行啊!体会自己的经历,虽然辛苦但也有收获。不想其他朋友再继续走我走过的路,浪费时间、精力,故成文以共享。

    废话少说,进入正题吧。

    第一步,当然我们需要首先导入word需要的库。通过ClassWizard->Add Class选择From a Type Library…定位需要的库文件导入。本例应该使用C:"Program Files"Microsoft Office"OFFICE11"MSWORD.OLB,在这里尽可选择所有的类导入,反正用的时候都有了,呵呵。完成这一步,我们得到两个文件msword.h和msword.cpp,那就加入你的工程吧。

 

说明:如果需要在VC++/MFC开发程序操作word/exceloffice元素,那么需要对必要的类型库进行导入.下面是office系列的类型库参考,导入类型库时候请选择正确的类型库进行导入.

       wordTables.ReleaseDispatch();

       wordRange.ReleaseDispatch();

       wordSelection.ReleaseDispatch();

       wordDoc.RecheckSmartTags();

       wordDocs.ReleaseDispatch();

       wordApp.ReleaseDispatch();

       returnTRUE;

}

注释如下:

1.       使用之前比忘记先进行COM环境的初始化,最好放在BOOLCMDIDemoApp::InitInstance()里吧。

//Initialize COM context

       if (FAILED(::CoInitialize(NULL)))

       {

              AfxMessageBox("Initialize COM context failed!");

              returnFALSE;

       }

2.       注意几个函数的用法:

a)       wordSelection.EndOf(COleVariant((short)6),COleVariant((short)0));

b)       wordSelection.EndKey(&CComVariant(10),&CComVariant(1));

c)       wordSelection.HomeKey(&CComVariant(5),&CComVariant(1));

d)       wordTable=wordTables.Add(wordRange,5/*row*/,4/*column*/,&defaultBehavior,&AutoFitBehavior);

这几个函数可以说是我收获最大的地方了,EndOf/EndKey/HomeKey实现了当前焦点的任意移动,比如到一个文档的末尾或者行尾、表格的操作位置等。举例来说:EndOf (VARIANT* Unit, VARIANT* Extend) 其第二个参数Extend决定了你是单纯的移动光标还是扩展移动选中内容。通过VBA参考,你可以知道wdMove=0 wdExtend=1,这样就可以决定是移动还是扩展选择内容了。

当然还有其他很多操作可以摸索,大可以先用word的宏录制,然后编写自己的VC代码,不过确实是个繁琐的过程,很多VBA常量需要查找具体的value替换。

通过预先的模版,你可以实现打开一个word模版,然后添加你自己的内容,灵活应用。然后保存为自己的报告。请参阅我的例子自己实现吧。Enjoy it by yourself...... J

由于时间关系,我还没有摸索通如何在word报告中插入图表(chart/bar/pie)以及如何插入图片jpg等,这样就可以做出图文并茂的报告了。如果你有经验,欢迎交流共享。
