Example

//This example sends a message to a remote connection to get a bitmap and send to the client
//This example also sets extra data to a sample string
//It is assumed that:
//1.  m_Inet is an object of the class LInet.
//2.  the network as been started (LInet::StartUp()) 
//3.  a connection has been established with a remote server (LInet::m_Inet.Connect())
//4.  GetNextCommandID() is a function that returns a unique command identifier
//5.  UpdateStatusbar() is a function that displays a message in the status bar
//6.  m_uWindowID is a window id that is received in the LInet::ResponseCallBack() as a result
//    of a call to m_Inet.SendCreateWinCmd()
//7.  m_uBitmapID is a bitmap id that is received in the LInet::ResponseCallBack() as a result
//    of a call to m_Inet.SendLoadCmd()
