我们在编写Word文档时，希望也能有CSDN博客中的代码插件的效果，可以插入带有行号和高亮显示的代码，然而这却不太容易做到。要做到这一点，有两种方式，一种是借助Notepad++，将内容导出为HTML格式，然后插入到Word中。这种方式的缺点是不能带行号，这对于想要解释代码来说，非常不方便。还有一种方式，就是我们通过Word中的VBA语言进行编程，来自动对代码段进行高亮显示和添加行号，这种方式可以由我们自己来定制，非常方便。以下代码参考了这篇博文（http://blog.chinaunix.net/uid-20672257-id-3323617.html），在此表示感谢。
在Word2007中要实现代码段的行号和高亮显示，我们首先定义一个新的样式来表示代码行。点击“开始”=》“样式”右下角的箭头，如下图所示：
如上图中红色圆圈处，在随后弹出的窗体中，点击新建样式，如下图所示：
在弹出的样式定义界面中，选择样式定义，如下图所示：
我们将进入段落编辑界面，如下图所示：
这是因为Word缺省的行距太大，我们希望代码紧凑一些，所以缩小了行距。因为要使代码突出显示，我们希望代码有一个柔和的底色，如下图所示：

在随后弹出的边框定义页面中，选择下图中红色圆圈选项：
我们可以将这个样式命名为code1。
至此，我们就定义了一个完整的代码段样式，下面我们就需要通过程序来对关键字、运算符进行高亮显示，并添加行号，我们将使用Word自带的VBA来实现这一功能，我们首先进入宏编辑界面，如下所示：
然后选择创建宏，将下面的代码粘到界面中：
'script to high light code In document

isKeyword = isSpecial(w, keys)
End Function
Private Function isSpecial(ByVal w As String, ByRef col As Collection) As Boolean
For Each i In col
If w = i Then
isSpecial = True
Exit Function
End If
Next
isspeical = False
End Function

Sub SyntaxHighlight()
Dim wordCount As Integer
Dim d As Integer
' set the style of selection
Selection.Style = "code1"
d = 0
wordCount = Selection.Words.Count
Selection.StartOf wdWord
While d < wordCount
d = d + Selection.MoveRight(wdWord, 1, wdExtend)
w = Selection.Text
If isKeyword(Trim(w)) = True Then
Selection.Font.Color = wdColorBlue
ElseIf isType(Trim(w)) = True Then
Selection.Font.Color = wdColorDarkRed
Selection.Font.Bold = True
ElseIf isOperator(Trim(w)) = True Then
Selection.Font.Color = wdColorBrown
ElseIf Trim(w) = "//" Then
'lIne comment
Selection.MoveEnd wdLine, 1
commentWords = Selection.Words.Count
d = d + commentWords
Selection.Font.Color = wdColorGreen
Selection.MoveStart wdWord, commentWords
ElseIf Trim(w) = "/*" Then
'block comment
While Selection.Characters.Last <> "/"
Selection.MoveLeft wdCharacter, 1, wdExtend
Selection.MoveEndUntil ("*")
Selection.MoveRight wdCharacter, 2, wdExtend
Wend
commentWords = Selection.Words.Count
d = d + commentWords
Selection.Font.Color = wdColorGreen
Selection.MoveStart wdWord, commentWords
End If
'move the start of selection to next word
Selection.MoveStart wdWord

Selection.MoveLeft wdWord, wordCount, wdExtend

End Sub
Private Sub SetLIneNumber(ByVal base As Integer)
Dim lines As Integer
lines = Selection.Paragraphs.Count
Selection.StartOf wdParagraph
For l = base To lines + base
lIneNum = l & " "
If l < 10 Then
lIneNum = lIneNum & " "
End If
Selection.Text = lIneNum
Selection.Font.Bold = False
Selection.Font.Color = wdColorAutomatic
p = Selection.MoveDown(wdLine, 1, wdMove)
Selection.StartOf wdLine
Next l
End Sub
上面的代码不太长，而且结构也很简单，大家可以自己去研究一下。与原始代码相比，这里为了高亮显示Python中的import等关键字，所以添加了新的关键字，另外，如果希望开始行号不是从1开始，可以修改SetLIneNumber函数调用中的参数，由1变为希望的值即可。
做好上述设置之后，我们就可以在Word中添加代码段了，添加完成之后，先选中这个代码段，然后点击“开发工具”=》“宏”，在如下界面中点击运行：
最终的效果如下所示：
如上所示，可以看出，我们添加的代码段可以非常好的和Word中的普通文本一起显示，达到了我们的目的。
