Question

The information on the version Exe-file I receive by means of VerQueryValue. Is there an inverse function (WinApi or Delphi) which can register (establish or change) such information?
Here, for example, there is a program which is able to do so. How may it work (http://www.angusj.com/resourcehacker)?

Answer 1

The version information is stored via resources; to edit that you simply need to edit that resource. Here is a unit I found that can clone an existing file version information and attach it to another file. It’s very easy to do what you want starting from this code (it’s coded by a friend of mine and is available public):

unit cloneinfo;

interface

uses Windows, SysUtils;

type
 LANGANDCODEPAGE = record
  wLanguage: Word;
  wCodePage: Word;
 end;

procedure clone(sFile,output:string);

implementation

procedure clone(sFile,output:string);
var
  dwHandle, cbTranslate: cardinal;
  sizeVers: DWord;
  lpData, langData: Pointer;
  lpTranslate: ^LANGANDCODEPAGE;
  hRes : THandle;
begin
 sizeVers := GetFileVersionInfoSize(PChar(sFile), dwHandle);
 If sizeVers = 0 then
 exit;
 GetMem(lpData, sizeVers);
 try
  ZeroMemory(lpData, sizeVers);
  GetFileVersionInfo (PChar(sFile), 0, sizeVers, lpData);
  If not VerQueryValue (lpData, '\VarFileInfo\Translation', langData, cbTranslate) then
  exit;
  hRes := BeginUpdateResource(pchar(output), FALSE);
  //For i := 0 to (cbTranslate div sizeof(LANGANDCODEPAGE)) do
  //begin
  lpTranslate := Pointer(Integer(langData) + sizeof(LANGANDCODEPAGE));
  UpdateResource(hRes, RT_VERSION, MAKEINTRESOURCE(VS_VERSION_INFO), lpTranslate^.wLanguage,lpData, sizeVers);
  //end;
  EndUpdateResource(hRes, FALSE);
 finally
  FreeMem(lpData);
 end;
end;


end.
