Andrue, I have found these 2 ZLIB's functions for compress/uncompress a 
buffer:
The COMPRESSSTRING works without error, but the UNCOMPRESSSTRING generates 
error Z_BUF_ERROR.
What is wrong ?

bool   COMPRESSSTRING( AnsiString &sString)
{
   ULONG ulBuffLen;
   char *szBuff=NULL;

   ulBuffLen = sString.Length() + pMaxBuffer;
   szBuff = new char[ulBuffLen+1];
   szBuff[ulBuffLen]='\0';
   memset(szBuff,'\0',ulBuffLen);

   ULONG ulRet = compress( szBuff, &ulBuffLen, sString.c_str() , 
sString.Length());
   if(Z_OK == ulRet){
        // Now the pointer of the original string will point to the 
compressed string.
       AnsiString  sResultStr(szBuff,ulBuffLen);
       sString = sResultStr;
       delete[] szBuff;       return true;
   }
   else{
      ShowMessage("Error Compression");      delete[] szBuff;      return 
false;
   }

}
//------------------------------------------------------------------------------
bool  UNCOMPRESSSTRING(AnsiString &sString)
{
  ULONG ulBuffLen;
  char *szBuff=NULL;

  ulBuffLen = sString.Length() + pMaxBuffer+12;
  szBuff = new char[ulBuffLen+1];
  szBuff[ulBuffLen]='\0';
  memset(szBuff,'\0',ulBuffLen);
  ULONG ulRet = uncompress(szBuff, &ulBuffLen,  sString.c_str(), 
sString.Length());
  if(Z_OK == ulRet){
      AnsiString  sResultStr(szBuff,ulBuffLen);
      sString = sResultStr;
      delete[] szBuff;      return true;
  }
  else{
      ShowMessage("Error uncompress: <" + IntToStr((int)ulRet) + ">"); 
delete[] szBuff;      return false;
   }
