在Qt Creator，eclipse等编辑器中，都默认有注释代码的快捷键：Ctrl + /。

注释快捷键在程序编程当中的作用相当明显，提高了编程效率。我在网上找到了一个在VC++6.0工具中添加注释快捷键的方法，VC++6.0是以VB为脚本来配置的。

首先，找到VC++6.0的安装路径，假设在：D:\Program Files (x86)\Microsoft Visual Studio 6.0，那么进入到Common\MSDev98\Macros目录下，全路径为：D:\Program Files (x86)\Microsoft Visual Studio 6.0\Common\MSDev98\Macros。

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

此时打开VC++6.0窗口，以下步骤：

1.打开菜单栏"Tools" -> "Customize" 打开了"Customize"对话框。

2.

3.

4.在代码中，只需要选中代码或者在光标所在行，执行快捷键"Ctrl + /"，进行注释或取消注释。
