Auto Increment Build Numbers for C# Projects in VS.NET 2003

Ok… I was really sick of incrementing the build number, each time that I built my project. Also, I know that I could use the NAnt task to increment build numbers, but this project does not have NAnt configuration files, and I don’t feel like writing them just to increment the build number. Since no one else has apparently created one of these for Visual Studio .NET C# projects, I hacked together this macro to do it autonomously. It basically opens up all projects in the solution (you can change this to only the active projects) and tries to open the corresponding AssemblyInfo.cs file in each project. You can specify which field you would like to increment, also. To install, do the following:

  1. Tools->Macros->New Macro Project
  2. Call it whatever you want. Example BuildMacros
  3. Alt-F11 (Opens up the Macros IDE)
  4. Copy and paste the macro code below, in the Module1 code.
  5. Rename Module1 macro to BuildIncrementer
  6. Open up EnvironmentEvents macro under BuildMacros (Or whatever you named your macro project)
  7. Add the following under the Automatically generated code region in the EnvironmentEvents macro

Private Sub BuildEvents_OnBuildDone(ByVal Scope As EnvDTE.vsBuildScope, ByVal Action As EnvDTE.vsBuildAction) Handles BuildEvents.OnBuildDone


End Sub

This is the macro:


Option Strict Off
Option Explicit Off
Imports EnvDTE

Public Module BuildIncrementer

    ‘ From
    Function GetProjectDir(ByVal FullName)

    Dim proj_path proj_path = Split(StrReverse(FullName), "", -1, 1)
    Dim count
    count = UBound(proj_path)
    Dim full_path full_path = ""

    Dim i
    For i = 1 To count

      full_path = full_path & "" & proj_path(i)


    GetProjectDir = StrReverse(full_path)

    End Function

    ‘ objSel- Represents the TextSelection object highlighting the version string to increment
    ‘ count- Represents the position, in the version string, to be incremented
    ‘ incrementBy- Represents a number to increment the version number by

    Sub ReplaceText(ByVal objSel As TextSelection, ByVal count As Integer, ByVal incrementBy As Integer)

      Dim strTemp As String() = Nothing
      Dim strTemp2 As String = ""
      Dim i As Integer = 0

      strTemp = objSel.Text.Split(".")
      Dim s As String
      For i = 1 To strTemp.Length – 1

        If i = count Then

          Dim oldValue As Integer = strTemp.GetValue(i)
          Dim newValue As Integer
          newValue = oldValue + incrementBy
          Dim strNewValue As String = newValue
          strTemp.SetValue(strNewValue, i)
          Exit For

        End If

      Next i

      objSel.Text = Join(strTemp, ".")

    End Sub
