Question

I used the macro mentioned in this question to comment a text selection in the CSS editor in VS 2008. I am looking for another macro which uncomments comments.

Answer 1

Just write a similar module/method, I think that should work, I haven’t tried, but this is what I think.
Please consider this as addition to the post that you have linked, you can look for the other details from that post.

Public Module UnCommentCSS
    Sub UnCommentCSS()
        Dim selection As TextSelection
        selection = DTE.ActiveDocument.Selection

        Dim selectedText As String
        selectedText = selection.Text

        If selectedText.Length > 0 _
           and selectedText.StartsWith("/*") _
           and selectedText.EndsWith("*/") Then
           selectedText = selectedText.Split("*"c)
           selection.Text = selectedText(1)
        End If
    End Sub
End Module

Note: this works if you have no nested * in between /* */
Otherwise you have to make necessary improvements/changes
