以上其实是通过com来调用office API，其他语言貌似也可以

当然你也可以用上面的代码将word文件转换成任意格式文件（只要office 2007支持，比如将word文件转换成PDF文件，把8改成17即可），下面是office 2007支持的全部文件格式对应表：

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照着字面意思应该能对应到相应的文件格式，如果你是office 2003可能支持不了这么多格式。word文件转html有两种格式可选wdFormatHTML、wdFormatFilteredHTML（对应数字8、10），区别是如果是wdFormatHTML格式的话，word文件里面的公式等ole对象将会存储成wmf格式，而选用wdFormatFilteredHTML的话公式图片将存储为gif格式，而且目测可以看出用wdFormatFilteredHTML生成的HTML明显比wdFormatHTML要干净许多。
