VS 2005 introduced new feature which confuses many people. Newly opened documents are placed in reverse order - to the left of already opened pages and not to the right as it used to be in VS 2002/2003 and as we know it from majority of programs that use tabbed interface. Existing documents are scrolled to the right. See MS Suggestion Page to see what I'm talking about.

Some people love this new feature while some hate it. MS has its arguments for this new design, see for example this forum. There are however reasons for traditional way too. For example, our VBdocman's Comment Editor can be placed as tabbed document.

Usually, user wants to have it on constant position and doesn't want it to be scrolled away. And of course, the biggest reason is personal attitude. I personally would appreciate if there was an option to turn this behavior on or off.

I searched for some add-in or macro that fixes this but couldn't find anything. So I tried to fix it myself. I must say that I haven't found a way how to do it perfectly with macro or add-in. You would probably need to create VSIP package. Despite this fact I created a macro that solves this problem. It causes VS 2005 to open new documents or tabbed tool windows to the right. It has the following issues:

• Short flickering when new document is opened. It's because all existing document windows are redrawn.
• After opening new document, VS forgets the order in which the documents had focus.
• It ignores the order of documents if you manually moved them (drag-and-drop) to another position.

To create and apply this macro:

1. Go to menu Tools - Macros - Macros IDE...
2. In the Macros IDE Class View navigate to MyMacros - {} MyMacros - EnvironmentEvents. Open (double-click) EnvironmentEvents.
3. Paste this code inside module (just before End Module line):
PLAIN TEXT
    Private timer As System.Threading.Timer
    Private ideTitle As String = Nothing

    Declare Auto Function SetWindowText Lib "user32" (ByVal hWnd As System.IntPtr, _
    ByVal lpstring As String) As Boolean

    '''<summary>Called when any window in VS gets activated.</summary>
    '''<param name="GotFocus">Window that got focus.</param>
    '''<param name="LostFocus">Window that lost focus.</param>
    Private Sub WindowEvents_WindowActivated(ByVal GotFocus As EnvDTE.Window, ByVal LostFocus As EnvDTE.Window) Handles WindowEvents.WindowActivated
        Try
            If timer Is Nothing Then
                ' Create timer which refreshes the caption because
                ' IDE resets the caption very often
                Dim autoEvent As New System.Threading.AutoResetEvent(False)
                Dim timerDelegate As System.Threading.TimerCallback = _
                    AddressOf tick
                timer = New System.Threading.Timer(timerDelegate, autoEvent, 0, 200)
            End If

            If GotFocus.Document Is Nothing Then
                ideTitle = Nothing
            Else
                ideTitle = GotFocus.Document.FullName
                showTitle(ideTitle)
            End If
        Catch ex As System.Exception
        End Try
    End Sub

    '''<summary>Called by timer.</summary>
    Public Sub tick(ByVal state As Object)
        Try
            If Not ideTitle Is Nothing Then
                showTitle(ideTitle)
            End If
        Catch ex As System.Exception
        End Try
    End Sub

    '''<summary>Shows the title in main window.</summary>
    Private Sub showTitle(ByVal title As String)
        SetWindowText(DTE.MainWindow.HWnd, ideTitle & " - " & DTE.Name)
    End Sub

4. That's all. Close macro IDE and restart VS.

How it works

This macro is slightly different than macros I already described because it handles VS events. To do so, you must write it in special module: EnvironmentEvents. In this case we handle WindowEvents.WindowActivated event. We check if there was new tabbed window opened. If yes, we hide all old windows and then show them again (by setting Visible property). This will cause that they will appear to the left so the new document will be the right-most one.

As I wrote, this is not perfect solution but you can experiment with it. Let us know if you find something better.
