   Hi Christophe,

   If you like this kind of stuff, you definitively must take a look to ReSharper. As you said, “once you get used to it, you can’t live without it”.

   Thanks, I’m moving from Linux dev and all the text editors I have ever used have had ctrl+d for duplicate line. I find it hard to believe this functionality was missing from VS2005! Thanks for the macro

   Thanks Christophe! I’ve been missing this from Eclipse… nice to have it back!

   Hi,
   I’m modified the macro so that if multiple line are selected, they are duplicated. If not, only the current line is dupplicated (as before).

   Note: The String.Replace function is used to prevent the “Automatic insertion of end constructs” option from being triggered, which would add uneeded additionnal end constructs.

   [CODE]
   Imports System
   Imports EnvDTE
   Imports EnvDTE80
   Imports System.Diagnostics

   Public Module DuplicateSelectionOrCurrentLineModule
   Sub DuplicateLine()
   Dim line As String
   line = DTE.ActiveDocument.Selection.Text
   If (line.Length = 0) Then
   DTE.ActiveDocument.Selection.StartOfLine(0)
   DTE.ActiveDocument.Selection.EndOfLine(True)
   line = DTE.ActiveDocument.Selection.Text
   End If
   line.Replace(ControlChars.NewLine, ControlChars.NewLine & “‘”)
   DTE.ActiveDocument.Selection.EndOfLine()
   DTE.ActiveDocument.Selection.NewLine()
   DTE.ActiveDocument.Selection.StartOfLine(0)
   DTE.ActiveDocument.Selection.Text = line
   End Sub
   End Module
   [/CODE]

   This didn’t work for me in VS 2008 Pro.

   Same here, this does not work with VS 2008 Pro.

   Ok, you have to Name your Macro “DuplicateLastLineModule” or if you want to change that name, you must change the name in the script file as well.
   After that, go to Tools -> Options -> Environment -> Keyboard.
   On the search box, enter
   Macros.[NAME OF THE MACRO MODULE].DuplicateLastLineModule.DuplicateLine

   Now you can assign a keyboard shortcut.

   Here’s a simpler, faster, and better (works with a single undo) way… The use of Collapse is not ideal, however:
   Imports EnvDTE
   Public Module DuplicateLine
   Sub DuplicateLine()
   Dim objSel As TextSelection = DTE.ActiveDocument.Selection
   If (objSel.IsEmpty()) Then
   objSel.SelectLine()
   End If
   objSel.Insert(objSel.Text, vsInsertFlags.vsInsertFlagsInsertAtEnd)
   objSel.Collapse()
   End Sub
   End Module

    this is my code to invert the equality on a line
    a = b becomes b = a
    Sub Invert()
    Dim line As String
    DTE.ActiveDocument.Selection.StartOfLine(0)
    DTE.ActiveDocument.Selection.EndOfLine(True)
    line = DTE.ActiveDocument.Selection.Text
    Dim EqMembers = line.Split(“=”)
    If EqMembers.Length > 0 Then
    DTE.ActiveDocument.Selection.EndOfLine()
    Dim newLine = EqMembers(1) + “=” + EqMembers(0)
    DTE.ActiveDocument.Selection.StartOfLine(0)
    DTE.ActiveDocument.Selection.EndOfLine(True)
    While newLine.IndexOf(” “) > -1
    newLine = newLine.Replace(” “, ” “)
    End While
    DTE.ActiveDocument.Selection.Text = newLine
    End If
    End Sub

    Thanks for sharing!
    I used the macro recorder in VS 2010 Pro. Your example was very helpful to connect macro and shortcut.
    Cheers

    Guys – if you do one thing for yourselves – you’ll read Scott Hanselman’s tool listings. Every decent developer knows that ReSharper is great (provided you’ve got either VS2008 and a maximum 3 year old machine – or VS2010 and a 64bit, 12 GB dev mmachine). If you have Visual Studio 2010 Professional and above, you can use the Extensions. (Tools > Extension Manager) for many of the features available as single downloads (VX10 Code Map, etc). Also – check out CodeRush from the guys over at DevExpress.

    Google is your friend. Everything is possible.

    Hi!
    Thanks for useful macro!
    Does anyone know how to achive similar results in VS Express, without Macro engine?

    You can also use built-in Visual Studio (at least 2010) feature: just put cursor on the line and press Ctrl+C > Ctrl+V in a sequence. Found here:
