使用Build获取FileVersion

Question

DelphiXe.

为了接收文件的版本我使用的功能:

function FileVersion(AFileName: string): string;
var
  szName: array[0..255] of Char;
  P: Pointer;
  Value: Pointer;
  Len: UINT;
  GetTranslationString: string;
  FFileName: PChar;
  FValid: boolean;
  FSize: DWORD;
  FHandle: DWORD;
  FBuffer: PChar;
begin
  try
    FFileName := StrPCopy(StrAlloc(Length(AFileName) + 1), AFileName);
    FValid := False;
    FSize := GetFileVersionInfoSize(FFileName, FHandle);
    if FSize > 0 then
    try
      GetMem(FBuffer, FSize);
      FValid := GetFileVersionInfo(FFileName, FHandle, FSize, FBuffer);
    except
      FValid := False;
      raise;
    end;
    Result := '';
    if FValid then
      VerQueryValue(FBuffer, '\VarFileInfo\Translation', p, Len)
    else
      p := nil;
    if P <> nil then
      GetTranslationString := IntToHex(MakeLong(HiWord(Longint(P^)),
        LoWord(Longint(P^))), 8);
    if FValid then
    begin
      StrPCopy(szName, '\StringFileInfo\' + GetTranslationString +
        '\FileVersion');
      if VerQueryValue(FBuffer, szName, Value, Len) then
        Result := StrPas(PChar(Value));
    end;
  finally
    try
      if FBuffer <> nil then
        FreeMem(FBuffer, FSize);
    except
    end;
    try
      StrDispose(FFileName);
    except
    end;
  end;
end;

对于大多数执行的文件和库,它返回正确的值.但是在某些文件中,版本被截断并显示没有Build.这里例如文件BASS.DLL(http://us.un4seen.com/files/bass24.zip)在Windows资源管理器中的文件属性中我看到版本2.4.7.1,函数result ='2.4.7':(

我通过Resourcehacker.exe(http://angusj.com/resourcehacker/)打开一个文件,我看结构VersionInfo:

1 VERSIONINFO
FILEVERSION 2,4,7,1
PRODUCTVERSION 2,4,0,0
FILEOS 0x4
FILETYPE 0x2
{
BLOCK "StringFileInfo"
{
    BLOCK "000004b0"
    {
        VALUE "CompanyName", "Un4seen Developments"
        VALUE "FileDescription", "BASS"
        VALUE "FileVersion", "2.4.7"
        VALUE "LegalCopyright", "Copyright © 1999-2010"
    }
}

BLOCK "VarFileInfo"
{
    VALUE "Translation", 0x0000 0x04B0
}
}

问题:如何收到2.4.7.1,即完整版？

如果您想要根块的文件版本,那么请忘记特定于语言的翻译:

function FileVersion(const FileName: TFileName): String;
var
  VerInfoSize: Cardinal;
  VerValueSize: Cardinal;
  Dummy: Cardinal;
  PVerInfo: Pointer;
  PVerValue: PVSFixedFileInfo;
begin
  Result := '';
  VerInfoSize := GetFileVersionInfoSize(PChar(FileName), Dummy);
  GetMem(PVerInfo, VerInfoSize);
  try
    if GetFileVersionInfo(PChar(FileName), 0, VerInfoSize, PVerInfo) then
      if VerQueryValue(PVerInfo, '\', Pointer(PVerValue), VerValueSize) then
        with PVerValue^ do
          Result := Format('v%d.%d.%d build %d', [
            HiWord(dwFileVersionMS), //Major
            LoWord(dwFileVersionMS), //Minor
            HiWord(dwFileVersionLS), //Release
            LoWord(dwFileVersionLS)]); //Build
  finally
    FreeMem(PVerInfo, VerInfoSize);
  end;
end;
