You can use a Visual C++ macro to do the job for you. I use the following code to do the job although it been that long since I implemented it I can't remember who to credit for the original version.

sub Application_BeforeBuildStart()
   if instr (ActiveConfiguration, "Release") then
      IncResVersion()
   end if
end sub

Sub IncResVersion()
   WindowCount = Windows.Count

   if WindowCount <> 0 then
      OldActiveWindow = ActiveWindow
   end if

   DspName = left(ActiveProject.FullName, len(ActiveProject.FullName)-3)+"dsp"
   Application.PrintToOutputWindow "Opening : "+DspName
   Documents.Open DspName, "Text"
   IsFind=ActiveDocument.Selection.FindText(".rc", dsMatchFromStart)

   if IsFind=false then
      if WindowCount=0 then
         ActiveWindow.Close dsSaveChangesPrompt
      elseif ActiveWindow<>OldActiveWindow then
         ActiveWindow.Close dsSaveChangesPrompt
      end if

      MsgBox "No .RC file found in project - terminating"
      exit sub
   end if

   ActiveDocument.Selection.StartOfLine
   ActiveDocument.Selection.CharRight dsMove, 7	
   ActiveDocument.Selection.EndOfLine dsExtend
   RCName = ActiveDocument.Selection

   if left (RCName, 2) = ".\" then RCName = mid (RCName, 3)
      if WindowCount=0 then
         ActiveWindow.Close dsSaveChangesPrompt
      elseif ActiveWindow<>OldActiveWindow then
         ActiveWindow.Close dsSaveChangesPrompt
      end if

      IncreaseVersionInFile (RCName)

      if WindowCount=0 then
         ActiveWindow.Close dsSaveChangesPrompt
      elseif ActiveWindow<>OldActiveWindow then
         ActiveWindow.Close dsSaveChangesPrompt
         Windows(OldActiveWindow).Active= True
      end if
End Sub

Sub IncreaseVersionInFile (Filename)
   Dim strOldFileVersion
   Dim strNewFileVersion
   Dim strOldProductVersion
   Dim strNewProductVersion
   Dim strSelection

   Application.PrintToOutputWindow "Opening : " + Filename

   ' Open the given resource script.
   Documents.Open (Filename), "Text"
   Windows(Filename).Active = True

   ' Save backup copy of file.
   ActiveDocument.Save (Filename+"~")

   ActiveDocument.Close() 
   Documents.Open Filename, "Text"
  
   Dim Sel
   Set Sel=ActiveDocument.Selection
   Sel.GoToLine 2
   Sel.SelectLine

   ' Only delete our comment.
   if left (Sel, 3) = "//#" Then		
      Sel.Delete
   else
      ' Insert our comment.
      Sel.StartOfLine	
   end if

   ' Write current date/time and add newline.
   Sel.Text ="//# Last version auto update " + CStr(now) + vbCrLf

   ' Find line with FileVersion Information.
   ActiveDocument.Selection.FindText "FILEVERSION", dsMatchForward + dsMatchFromStart + dsMatchCase + dsMatchWord

   ' Move to eol and then to end of build number.
   ActiveDocument.Selection.EndOfLine

   ' Mark Build Number and store in strSelection
   ActiveDocument.Selection.WordLeft dsExtend, 1

   Set strSelection = ActiveDocument.Selection
   strOldFileVersion = strSelection.Text
   strNewFileVersion = strOldFileVersion + 1

   ' Replace file entry.
   strSelection.Text = strNewFileVersion

   ActiveDocument.Selection.FindText "PRODUCTVERSION", dsMatchForward + dsMatchFromStart + dsMatchCase + dsMatchWord

   ' Move to eol and then to end of build number.
   ActiveDocument.Selection.EndOfLine

   ' Mark Build Number and store in strVersion.
   ActiveDocument.Selection.WordLeft dsExtend, 1

   Set strSelection = ActiveDocument.Selection
   strOldProductVersion = strSelection.Text
   strNewProductVersion = strOldProductVersion + 1

   ' Replace the entry.
   strSelection.Text = strNewProductVersion

   ' Info block.
   ActiveDocument.Selection.FindText "VALUE ""FileVersion"",", dsMatchForward + dsMatchFromStart + dsMatchCase  

   ' Move to eol and then to end of build number.
   ActiveDocument.Selection.EndOfLine
   ActiveDocument.Selection.CharLeft dsMove, 3 

   ' Mark Build Number and store in strVersion.
   ActiveDocument.Selection.WordLeft dsExtend, 1

   Set strSelection = ActiveDocument.Selection
   strSelection.Text = strNewFileVersion

   ActiveDocument.Selection.FindText "VALUE ""ProductVersion"",", dsMatchForward + dsMatchFromStart + dsMatchCase  

   ' Move to eol and then to end of build number.
   ActiveDocument.Selection.EndOfLine
   ActiveDocument.Selection.CharLeft dsMove, 3 

   ' Mark Build Number and store in strVersion.
   ActiveDocument.Selection.WordLeft dsExtend, 1
   Set strSelection = ActiveDocument.Selection
   strSelection.Text = strNewProductVersion
End Sub 

This is one of the more useful macros for the Visual C++ IDE, I will add this to the UT knowledge base.
