word轉pdf主要是利用word自帶的函式，主要有三個函式(1)Saveas();(2)PrintOut();(3)ExportAsFixedFormat();這三個

函式可以實現：下面著重對其進行說明：

函式原型public: Void SaveAs( &Object^ FileName, //檔名含路徑名，例如COleVariant(CW2T(_T("G:\\C++\\MFC2table1\\000.pdf"))) &Object^ FileFormat, //    17:wdFormatpdf &Object^ LockComments, //置false；COleVariant((short)false), &Object^ Password

,     //置空；COleVariant(_T("")) &Object^ AddToRecentFiles, //置false；COleVariant((short)false), &Object^ WritePassword, //置空；COleVariant(_T("")) &Object^ ReadOnlyRecommended, //置false；COleVariant((short)false), &Object^ EmbedTrueTypeFonts, //置false；COleVariant((short)false), &Object^ SaveNativePictureFormat, //置false；COleVariant((short)false), &Object^ SaveFormsData, //置false；COleVariant((short)false), &Object^ SaveAsAOCELetter, //置false；COleVariant((short)false), &Object^ Encoding, //置false；COleVariant((short)false), &Object^ InsertLineBreaks, //置false；COleVariant((short)false), &Object^ AllowSubstitutions, //置false；COleVariant((short)false), &Object^ LineEnding, //置false；COleVariant((short)false), &Object^ AddBiDiMarks//置false；COleVariant((short)false), );

對於printOut()而言word中必須存在這個選項才可以執行；而ExportAsFixedFormat()似乎在C++中不能被呼叫成功，MSDN中C++就沒有該函式，在C#中可以實現

其中主要第二個引數的設定：
