Andrue, very thanks for your sample that works PERFECTLY with the magic 
vector<BYTE> !
Here your code with some added for testing returned value came from compress 
and uncompres zlib.
Thanks again, you are not TeamB by chance but by experience !

================================
#include <vector>
#include <zlib.h>
#define   MULTIPLICATOR_FACTOR 3

//------------------------------------------------------------------------------
bool compress( AnsiString const & sInputStr ,std::vector<BYTE> &result)
{
  //Alloue un Buffer �gale � 2 fois la taille de la chaine � d�compresser
  int iSizeBuf = MULTIPLICATOR_FACTOR * sInputStr.Length();
  std::vector<BYTE> resultTempo(iSizeBuf); // Allow for an overhead
  DWORD len=resultTempo.size();

   if(Z_OK == compress(&(resultTempo[0]),&len, reinterpret_cast<BYTE 
*>(sInputStr.c_str()),sInputStr.Length())){
           //Ajuste la taille � len qui est la taille r�elle utilis�e
           resultTempo.resize(len);
           result=resultTempo;
           return true;
   }

   return false;
}

//------------------------------------------------------------------------------

bool decompressData( std::vector<BYTE> DecompressBuffer, AnsiString 
&sResult)
{
  //Taille du bufer qui contiendra la chaine d�compress�e
  size_t SizeArray = MULTIPLICATOR_FACTOR * DecompressBuffer.size();
  std::vector<BYTE> result(SizeArray);

  DWORD len=result.size();
  if(Z_OK == 
uncompress(&(result[0]),&len,&(DecompressBuffer[0]),DecompressBuffer.size())){
          sResult =  (AnsiString)reinterpret_cast<char *>(&(result[0]));
          sResult.SetLength(len);
          return true;
  }

  return false;

}
//---------------------------------------------------------------------------

#pragma argsused
int main(int argc, char* argv[])
{
  AnsiString sInput="I am testing the fabulous ZLIB compression library !!";
  AnsiString sOutput;

  std::vector<BYTE> compressedData;
  if(!compress(sInput,compressedData))
       return 0;

  if(decompressData(compressedData, sOutput))
          ShowMessage("["+sOutput+"]");
  else
          ShowMessage("Decompression error");


  return 0;
