Macro to generate a c++ header file using excel - vba

Question

I am thinking to make a excel file which can generate a headre file for my c++ source file.
Previoulsy we used to generate .h files using excel but i dont know the logic behind that(Hope some macros using for that).
My header file contains this many data and my intention is to give "MYapp Alpha 0.0.3" through excel file because the version number changes for each release. If I used excel file then I can edit that excel and it creates .h file for me, later some more informations I can make configurable through excel file.
Is it possible to write macro that edit "MYapp Alpha 0.0.3" without touching other
#define APP_FLASH_APP_ID 0x123
#define APP_VERSION_NUM "MYapp Alpha 0.0.3 "
#define APP_PRODUCT_NAME "TPI "
#define APP_DESCRIPTION_STR APP_PRODUCT_NAME APP_VERSION_NUM
#define APP_RELEASE_DATE_STR "10/11/13"
#define APP_SOFTWARE_PARTNUM_LEN 10
Some valuable help or suggestions needed
Have a great day

I think this could help you:
Sub test()
Const strVerNumber As String = "0.0.4"
Dim FS, TSsource
Set FS = CreateObject("Scripting.FileSystemObject")
Set TSsource = FS.OpenTextFile("C:\test.txt", 1, 2)
Dim tmpString As String
tmpString = TSsource.ReadAll
TSsource.Close
tmpString = Replace(tmpString, _
"MYapp Alpha 0.0.3", _
"MYapp Alpha " & strVerNumber)
Dim TSout
Set TSout = FS.Createtextfile("C:\testOUT.txt", True)
TSout.Write tmpString
TSout.Close
End Sub

Well basically a .h file is a text file. So you need to do some string processing, open a text file, print the data in it and close it.
To open and close a text file use this:
Dim fso As Object
Set fso = CreateObject("Scripting.FileSystemObject")
Dim oFile As Object
Set oFile = fso.CreateTextFile("D:\test.h")
oFile.WriteLine "tfadfadsest"
oFile.Close
Set fso = Nothing
Set oFile = Nothing
