Just write the data's size to the socket before writing the actual data, and
then read the size before reading the data, ie:

    int size = the data size;
    ...->SendBuf(&size, sizeof(int));
    ...->SendBuf(buffer, size);

    //...

    void __fastcall TLanServerThread::ClientExecute()
    {
        TWinSocketStream *Stream = new TWinSocketStream(ClientSocket, 5000);
        try
        {
            while( (!Terminated) && (ClientSocket->Connected) )
            {
                if( Stream->WaitForData (5000) )
                {
                    int size = 0;
                    if( !ReadData(Stream, &size, sizeof(int)) )
                        break;

                    char *buffer = new char[size];
                    try
                    {
                        if( ReadData(Stream, buffer, size) )
                            // use your buffered data as needed...
                    }
                    __finally {
                        delete[] buffer;
                    }
                }
            }
        }
        __finally
        {
            delete Stream;
        }
    }
