　　String __fastcall TForm1::GetFileVersion(String FileName)
{
int iVerInfoSize;
char *pBuf;
AnsiString asVer="";
VS_FIXEDFILEINFO *pVsInfo;
unsigned int iFileInfoSize = sizeof( VS_FIXEDFILEINFO );

iVerInfoSize = GetFileVersionInfoSize(FileName.c_str(), NULL);
if(iVerInfoSize!= 0)
  {
  pBuf = new char[iVerInfoSize];
  if(GetFileVersionInfo(FileName.c_str(),0, iVerInfoSize, pBuf ) )
    {
    if(VerQueryValue(pBuf, "//",(void **)&pVsInfo,&iFileInfoSize))
      {
      asVer  = IntToStr( HIWord(pVsInfo->dwFileVersionMS) )+".";
      asVer += IntToStr( LOWORD(pVsInfo->dwFileVersionMS) )+".";
      asVer += IntToStr( HIWORD(pVsInfo->dwFileVersionLS) )+".";
      asVer += IntToStr( LOWORD(pVsInfo->dwFileVersionLS) );
      }
    }
  delete pBuf;
  }
