SUMMARY
=======

Visual C++ doesn't have a feature to automatically increment the version
resource information of your project after each build. This article describes
one way to provide such a feature.

MORE INFORMATION
================

You can write a program to modify the resource compiler (.rc) file instead of
using the steps described here. However, the RC file is under the control of
Visual C++. Visual C++ modifies the RC file while saving, and this may affect
the version resource. The approach described in this section can be applied to
any Visual C++ project. This example uses a Microsoft Foundation Classes
project.

Create a new project using the MFC (EXE) Appwizard and call it "MyProject"
(without the quotation marks). MyProject will have a MyProject.rc file, which
includes MyProject.rc2. The .rc2 file is meant for user-defined resources.
Follow these steps to increment MyProject's version information after each
build:

1. Remove the version resource from the .rc file and place it in the .rc2 file:

   a. Open both MyProject.rc and MyProject.rc2 (found in the Res folder), in a
      text editor. To use the Visual C++ editor, click Open on the File menu and
      select Text in the Open As list for the MyProject.rc file.

   b. Find the version resource statements in MyProject.rc. It should look
      something like:

   /////////////////////////////////////////////////////////////////////// 
   // 
   // Version
   // 

   VS_VERSION_INFO VERSIONINFO
    FILEVERSION 1,0,0,1
    PRODUCTVERSION 1,0,0,1
    FILEFLAGSMASK 0x3fL
   #ifdef _DEBUG
    FILEFLAGS 0x1L
   #else
    FILEFLAGS 0x0L
   #endif
    FILEOS 0x4L
    FILETYPE 0x1L
    FILESUBTYPE 0x0L
   BEGIN
       BLOCK "StringFileInfo"
       BEGIN
           BLOCK "040904b0"
           BEGIN
               VALUE "Comments", "Sample Application\0"
               VALUE "CompanyName", "Microsoft Corp.\0"
               VALUE "FileDescription", "MyProject MFC Application\0"
               VALUE "FileVersion", "1, 0, 0, 1\0"
               VALUE "InternalName", "MyProject\0"
               VALUE "LegalCopyright", "Copyright (C) 1999\0"
               VALUE "OriginalFilename", "MyProject.EXE\0"
               VALUE "ProductName", "MyProject Application\0"
               VALUE "ProductVersion", "1, 0, 0, 1\0"
           END
       END
       BLOCK "VarFileInfo"
       BEGIN
           VALUE "Translation", 0x409, 1200
       END
   END

   c. Cut the version resource from the MyProject.rc file and paste it into the
      MyProject.rc2 file below the comment "Add manually edited resources here."
      For information about what each one of the fields in the resource means,
      see the VERSIONINFO resource statement in Help.

2. Replace the FILEVERSION and PRODUCTVERSION data with macros FILEVER and
   PRODUCTVER. Similarly, replace the FileVersion and ProductVersion string data
   with the macros STRFILEVER and STRPRODUCTVER.

3. Add a #include "VersionNo.h" (without the quotation marks) immediately before
   the VS_VERSION_INFO resource statement. Now the version resource will look
   like:

   /////////////////////////////////////////////////////////////////////// 
   // 
   // Version
   // 
   #include "VersionNo.h"
   VS_VERSION_INFO VERSIONINFO
    FILEVERSION FILEVER
    PRODUCTVERSION PRODUCTVER
    FILEFLAGSMASK 0x3fL
   #ifdef _DEBUG
    FILEFLAGS 0x1L
   #else
    FILEFLAGS 0x0L
   #endif
    FILEOS 0x4L
    FILETYPE 0x1L
    FILESUBTYPE 0x0L
   BEGIN
       BLOCK "StringFileInfo"
       BEGIN
           BLOCK "040904b0"
           BEGIN
               VALUE "Comments", "Sample Application\0"
               VALUE "CompanyName", "Microsoft Corp.\0"
               VALUE "FileDescription", "MyProject MFC Application\0"
               VALUE "FileVersion", STRFILEVER
               VALUE "InternalName", "MyProject\0"
               VALUE "LegalCopyright", "Copyright (C) 1997\0"
               VALUE "OriginalFilename", "MyProject.EXE\0"
               VALUE "ProductName", "MyProject Application\0"
               VALUE "ProductVersion", STRPRODUCTVER
           END
       END
       BLOCK "VarFileInfo"
       BEGIN
           VALUE "Translation", 0x409, 1200
       END
   END

4. Create a header file called VersionNo.h in the same directory as your
   project. This file will contain the following statements, which are the
   definitions for macros used in step 2:

   #define FILEVER        1,0,0,1
   #define PRODUCTVER     1,0,0,1
   #define STRFILEVER     "1, 0, 0, 1\0"
   #define STRPRODUCTVER  "1, 0, 0, 1\0"

   NOTE: Add linefeed and carriage return characters on the last line.

   Now, MyProject.rc file includes MyProject.rc2, and MyProject.rc2 file includes
   VersionNo.h.

5. The VersionNo.h file contents will be modified using a Visual Basic Script
   macro. The macro described below handles the Visual C++ BuildFinish event, so
   it will not be fired until a build completes. Whenever this VB Script code is
   called, it first increments the version numbers inside the header file by a
   fixed amount, then it saves the file and closes it. During a subsequent
   build, the new version number is included in the executable.

   To install and use the VB Script code, do the following:

   a. Open an existing DSM (macro) file or create a new DSM file in Visual C++.
      To create a new file, click New on the File menu, select Macro File on the
      Files tab, give it a name, and click OK.

   b. Paste the following VB Script code below (an empty DSM file cannot be
      installed in Visual C++; the next step explains installing):

   Function GetProjectDir(FullName)

   'VC++ doesn't provide any method for getting the path of the active project
   'See the VB Script reference for more information on the VB Script functions 
   'used in this function

   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)
   next

   GetProjectDir = StrReverse(full_path)

   End Function

   Sub ReplaceText(selection, count, incrementby)

   'selection represents the TextSelection object
   'count represents the position of the version number to be incremented
   'incrementby represents a number that will be added to the existing version number

   selection.WordRight dsMove, count
   selection.WordRight dsExtend, 1
   Dim str
   str = selection.Text
   str = str + incrementby

   selection.Text = str

   End Sub

   Sub Application_BuildFinish(numError, numWarning)

   'This event will be triggered after every build of a project
   'You can check numError and/or numWarning to determine if you want to continue
   'If numError <> 0 Then
       'exit sub
   'Obtain the full path of the active project
   Dim full_path
   full_path = GetProjectDir(ActiveProject.FullName)

   full_path = full_path & "versionno.h"

   'Open the VersionNo.h file
   Documents.Open full_path

   'Obtain the TextSelection object
   Dim selection
   set selection = ActiveDocument.Selection
   selection.StartOfDocument 

   'Increment the version information
   ReplaceText selection, 9, 1
   selection.LineDown
   selection.StartOfLine
   ReplaceText selection, 9, 1
   selection.LineDown
   selection.StartOfLine
   ReplaceText selection, 10, 1
   selection.LineDown
   selection.StartOfLine
   ReplaceText selection, 10, 1

   ActiveDocument.Save
   ActiveDocument.Close
    
   End Sub

      NOTE: This code is an unsupported sample. You may modify it for your build
      scenario.

   c. Install the DSM file if it is not already installed. To install, click
      Customize on the Tools menu, click the Add-in and Macro Files tab, browse
      to select the DSM file, and click Close.

6. Select Build MyProject.exe from the Build menu. After the build finishes,
   open the VersionNo.h file. It will contain the following statements:

   #define FILEVER        1,0,0,2
   #define PRODUCTVER     1,0,0,2
   #define STRFILEVER     "1, 0, 0, 2\0"
   #define STRPRODUCTVER  "1, 0, 0, 2\0"

   If you build the code again, this version information in included in the
   executable, and the version information is incremented. You can introduce
   some code in the macro described earlier to prevent incrementing version
   numbers if the build produced errors.
