Andrue I have changed the uncompres fonction, like this:
char *  UNCOMPRESSSTRING(char * szString, char *szBuff)
{
    ULONG ulBuffLen;

    int iErrorCode = Z_BUF_ERROR;
    ulBuffLen = lstrlen(szString) + BUFFER_SIZE;
    do{
        ulBuffLen = ulBuffLen *2;
        szBuff = new char[ulBuffLen];
        ZeroMemory(szBuff,ulBuffLen);
        iErrorCode = uncompress(szBuff, &ulBuffLen,  szString, 
lstrlen(szString));
    }while (iErrorCode == Z_BUF_ERROR);

    if (iErrorCode != Z_OK){

       switch (iErrorCode)
          {
              case Z_MEM_ERROR : throw Exception ("UnCompress: Not enough 
memory");
              case Z_DATA_ERROR: throw Exception ("UnCompress: Input data is 
corrupted");
              default          : throw Exception ("UnCompress: Unknown 
error");
          }
       }
But it loops in the while with no stop, whereas by debug I have found that 
the content of  szBuff is fine and match exactly the compress string for the 
*first pass* in the while ??
I don't understood what is wrong ?
