I have to admit I haven’t taken advantage of enough of VS.NET’s capabilities… the ability to write macros alone should have resulted in a ton of useful little routines, but I have only written a few. One of the ones I use most often converts between a list of my internal member variables in a class…

    Dim m_fred As String
    Dim m_counter As Integer

to the bare-bones properties

    Public Property fred() As String
            Return m_fred
        End Get
        Set(ByVal Value As String)
            m_fred = Value
        End Set
    End Property

    Public Property counter() As Integer
            Return m_counter
        End Get
        Set(ByVal Value As Integer)
            m_counter = Value
        End Set
    End Property

It is dependent on my particular hungarian-ish (m_) naming style for internal variables and it doesn’t deal well with arrays or variables that get instantiated in their declarations… but I find it a real timesaver to spit out that initial pass at the properties before I go in and add any validation or whatever else I was going to do… On the off chance that you might find it useful as well, or that you want to “finish it up”, here is the source of the macro:

Sub ConvertProperties()
        Dim txt As TextSelection
        txt = DTE.ActiveDocument.Selection

        Dim line, originalCode As String
        originalCode = txt.Text

        Dim lines() As String
        lines = Split(originalCode, vbLf)
        Dim variableName As String
        Dim publicName As String
        Dim dataType As String
        Dim propertyProcedure As String

        Dim r As Regex
        r = New Regex( _
        "(Dim|Private)\s*(?<varname>\S*)\s*As\s*(?<typename>\S*)", _
        RegexOptions.IgnoreCase Or RegexOptions.ExplicitCapture)

        For Each line In lines
            line = line.Trim
            If Not line = "" Then
                Dim mtch As Match
                mtch = r.Match(line)
                If mtch.Success Then
                    variableName = mtch.Groups("varname").Value.Trim
                    dataType = mtch.Groups("typename").Value.Trim
                    publicName = variableName.Substring(2)

                    propertyProcedure = _
                        String.Format("{0}Public Property {1} As {2}{0}" _
                            & "    Get{0}" _
                            & "        Return {3}{0}" _
                            & "    End Get{0}" _
                            & "    Set(ByVal Value As {2}){0}" _
                            & "        {3} = Value{0}" _
                            & "    End Set{0}" _
                            & "End Property", vbCrLf, publicName, _
                            dataType, variableName)

                    txt.Insert(vbCrLf & propertyProcedure, _
                End If

            End If
        'don't do anything
        'but I don't want to see an error!
    End Try
End Sub

Anyone have some real cool/useful VS.NET macros?
