以上其實是通過com來調用office API，其他語言貌似也可以

當然你也可以用上面的代碼將word文件轉換成任意格式文件（只要office 2007支持，比如將word文件轉換成PDF文件，把8改成17即可），下面是office 2007支持的全部文件格式對應表：

wdFormatDocument                    =  0
wdFormatDocument97                  =  0
wdFormatDocumentDefault             = 16
wdFormatDOSText                     =  4
wdFormatDOSTextLineBreaks           =  5
wdFormatEncodedText                 =  7
wdFormatFilteredHTML                = 10
wdFormatFlatXML                     = 19
wdFormatFlatXMLMacroEnabled         = 20
wdFormatFlatXMLTemplate             = 21
wdFormatFlatXMLTemplateMacroEnabled = 22
wdFormatHTML                        =  8
wdFormatPDF                         = 17
wdFormatRTF                         =  6
wdFormatTemplate                    =  1
wdFormatTemplate97                  =  1
wdFormatText                        =  2
wdFormatTextLineBreaks              =  3
wdFormatUnicodeText                 =  7
wdFormatWebArchive                  =  9
wdFormatXML                         = 11
wdFormatXMLDocument                 = 12
wdFormatXMLDocumentMacroEnabled     = 13
wdFormatXMLTemplate                 = 14
wdFormatXMLTemplateMacroEnabled     = 15
wdFormatXPS                         = 18照着字面意思應該能對應到相應的文件格式，如果你是office 2003可能支持不了這么多格式。word文件轉html有兩種格式可選wdFormatHTML、wdFormatFilteredHTML（對應數字8、10），區別是如果是wdFormatHTML格式的話，word文件里面的公式等ole對象將會存儲成wmf格式，而選用wdFormatFilteredHTML的話公式圖片將存儲為gif格式，而且目測可以看出用wdFormatFilteredHTML生成的HTML明顯比wdFormatHTML要干凈許多。
