不止一位问道可不可以在CVF中为多行代码加注释。
CVF本身无这样的功能，但是可以用macro功能自己添!而且是添加工具钮！
俺初步试验成功，虽然在容错性方面还可以改进，但已经基本够用，特奉献给大家。

[color=FF0000]做法：[/color]

(1) 在..\Microsoft Visual Studio\Common\MSDEV98\MACROS文件夹下生成文件GrpComment.dsm
(2) 用文本编辑器打开该文件，将以下所附的代码贴在其中，保存（注意保留.dsm后缀）
(3) 启动CVF，选Tools=>Customize=>Add-ins and Macro Files
(4) 在GrpComment前打勾，去掉其他的勾
(5) 在同一对话框中选Commands=>Macros，此时在右边可以看见CommentDel和CommentOut
(6) 选中CommentOut，拖到CVF的工具栏上去（添加工具钮），会弹出Button Appearance对话框
(7) 选Image and text，在下边Button text框中输入名称（默认是CommentOut），如“加注释”
(8) 类似的方法再将CommentDel命令以工具钮的形式添加到工具栏上，名称可取为“去注释”

这时，工具栏上应该多了两个工具钮：“加注释”和“去注释”。

[color=FF0000]用法：[/color]

加注释：选择要加注释的多行代码，点击“加注释”按钮即可；
去注释：选择已经注释的多行代码，点击“去注释”按钮即可。

[color=FF0000]适用：[/color]后缀为f90或f77的代码文件。
