My bad. I thought track bar and scroll bar were the same thing. I now see that you are referring to a "slider control." Can you get the dimensions of the dialog bar, and then add a few to those dimensions during the creation of the track bar?

The same way you handle any window messages (assuming you're using MFC doc/view)

// Add to class
afx_msg void OnNcLButtonUp(UINT nHitTest, CPoint point);

// Add to message map 
ON_WM_NCLBUTTONUP()

// Add implementation of handler method
void CMyWndClass::OnNcLButtonUp(UINT nHitTest, CPoint point)
{
   baseclass::OnNcLButtonUp(nHitTest, point);

   ... do stuff...
}

I haven't tested this, but it's possible the default WM_NCLBUTTONDOWN message handler
is capturing the mouse and sitting in a modal loop until the WM_NCLBUTTONUP is
received. This would be for the default window dragging.

You may have to do the same.

Responding to just the WM_NCLBUTTONUP message is unique. What are you wanting to
do when you receive that message? Maybe there's a simpler alternative.

It looks like you're either missing a file, or the compiler can't find it. Is there a DSplit.rc2 file in a res directory within your project's directory? If not, either find the file or comment out the #include line and see what happens.

Hi, I am designing c++/MFC plugins for a certain CNC machine tool control system. I use (and have to use for the application VS2003, and VC++/MFC).
I am Brand new, and trying to be "self taught", but there really is no step by step beginners books (at least that I found), that teach VS2003 and VC++/MFC.

Since I am stuggling badly, would anyone perhaps around the Knoxville, TN area be willing to teach, perhaps private tutoring, I will pay if I can afford you for your time.

If it is a posibility for you could you email me at, replace the "AT" with @.

a very strange problem about socket

kcynic11-Aug-07 1:50

kcynic

11-Aug-07 1:50

I need a stream socket to listen other connects. So,I have to create a socket using such code:
if(m_listenSock.Create())
{
SOCKET soc=m_listenSock.m_hSocket;
BOOL ret= m_listenSock.Listen(10);
}
that,m_listenSock is a member of a class,and the socket also do not go out its scope. But after the codes performed I use "netstat -a" in the cmd line could not find the new listen port in the list.And other socket also could not connect to such socket;
But when I change it to
if(m_listenSock.Create())
{
SOCKET soc=m_listenSock.m_hSocket;
m_listenSock.Close();
if(m_listenSock.Create(soc))
m_listenSock.Listen(10);
}
as a result,the new port would be listed in the list.and other socket can also connect to the new socket.

And if I only could do such work using the second way,the new problem will occur,i.e. if when the socket was closed and before created using the old port but there is another process or thread create a new socket with the same port,the code: m_listenSock.Create(soc) would fail or create using another avalid port!It is not what I want to.

How to resolve such problem?
Thanks.
GOOD LUCK.

There is no "strange problem about socket". It works the way you code it to work.
It looks like you're blindly attempting to do something you don't know much about.

You need to choose a port for your socket to listen on.

A SOCKET is not a port number.

That,if what you said is really true,but there also would be two question :

1. What is the member m_hSocket of the CAsyncSocket? And if I use Create() to create a socket with a random port ,how can I get the port of the socket?
2.I real work is to create a listen socket and report the port of the listening socket to the server and other client can get the port from the server and connect to the client with such listening socket. If I report the m_hSocket number of the listen socket to the server,although other clients can get the number,they can't connect to the listening socket!

Thanks.

m_hSocket is a SOCKET - a handle to a socket. To get the address assigned to
your socket, including the port, you can use GetSockName():

    if (MySocket.Create(0, SOCK_STREAM))
    {
       CString SockAddrStr;
       UINT port;
       MySocket.GetSockName(SockAddrStr, port);

       MySocket.Listen();
    }

"port" is the port number that other peers should connect to. They'll need the
IP address as well.

oh,my God,it is so great!
I see now,the port is really different with the SOCKET member of the Socket!
Thanks.
But when I test the guide of you given,the SockAddrStr always be fill with "0.0.0.0"!why?

Thanks.

Because you haven't specifically bound the socket to one adapter - there's no specific
IP address.

If you want the IP address(es) of the machine, you can use the sockets APIs gethostname()
and gehostbyname() (or the newer getaddrinfo()). Note that you can only get a local LAN IP
address if you're on a LAN, not the public IP needed by peers outside the LAN.
