找到VC++6.0的安装路径下的 Microsoft Visual Studio 6.0\Common\MSDev98\Macros 路径
在该目录新建一个文本文件，并重命名为：comment.dsm，并打开增加以下内容：
Sub CustomCommentOut()
'DESCRIPTION: 注释/取消注释宏，可处理VB和C++、Java注释
Dim win
set win = ActiveWindow
If win.type <> "Text" Then
MsgBox "This macro can only be run when a text editor window is active."
Else
TypeOfFile = 3
If TypeOfFile > 0 And TypeOfFile < 6 Then
If TypeOfFile > 3 Then
CommentType = "'"' VB注释
CommentWidth = 1
Else
CommentType = "//"' C++、java 注释
CommentWidth = 2
End If
StartLine = ActiveDocument.Selection.TopLine
EndLine = ActiveDocument.Selection.BottomLine
If EndLine < StartLine Then
Temp = StartLine
StartLine = EndLine
EndLine = Temp
End If
' 单行
If EndLine = StartLine Then
ActiveDocument.Selection.StartOfLine dsFirstColumn
ActiveDocument.Selection.CharRight dsExtend, CommentWidth
If ActiveDocument.Selection = CommentType Then
ActiveDocument.Selection.Delete
Else
ActiveDocument.Selection.StartOfLine dsFirstText
ActiveDocument.Selection.CharRight dsExtend, CommentWidth
If ActiveDocument.Selection = CommentType Then
ActiveDocument.Selection.CharRight dsExtend
ActiveDocument.Selection.Delete
Else
ActiveDocument.Selection.StartOfLine dsFirstText
ActiveDocument.Selection = CommentType + vbTab + _
ActiveDocument.Selection
End If
End If
' 多行
Else
For i = StartLine To EndLine
ActiveDocument.Selection.GoToLine i
CommentLoc = dsFirstColumn
ActiveDocument.Selection.StartOfLine CommentLoc
ActiveDocument.Selection.CharRight dsExtend, CommentWidth
If ActiveDocument.Selection = CommentType Then
ActiveDocument.Selection.Delete
Else
ActiveDocument.Selection.StartOfLine CommentLoc
ActiveDocument.Selection = CommentType + _
ActiveDocument.Selection
End If
Next
End If
Else
MsgBox("Unable to comment out the highlighted text" + vbLf + _
"because the file type was unrecognized." + vbLf + _
"If the file has not yet been saved, " + vbLf + _
"please save it and try again.")
End If
End If
End Sub
