Thanks. Anything I need to be careful to select or not to select when I create the project in VC? When you say implement handlers, do you mean each message gets it own handle and is processed from that perspective?
I would suggest you forget about the TCP stuff until you have mastered the text viewer and scrolling. Whether you use simple Win32 or MFC this can be quite a challenge and TCP would only complicate matters. Start with a view window and add the scroll features then add a mechanism to send some lines of text, say up to 100 and see that your scrolling is working. Then when you have all those features under control you can start to add the more complex pieces of the TCP feed.
To get myself starting I would like to write an app that simply receives messsages over a tcp connection and displays them to a scrolling window.
Hi Alan! I suggest an alternative approach without multi threading to get up and running quickly:
1) create a new MFC project and add a CListBox control: Using the CListBox control[^], this comes with a working example dialog project. 2) Add a TCP client socket such as CAsyncSocket to your dialog: Socket Programming with MFC (Part 1)[^], this will also explain which initialisation is needed in your application. 3) Add a button to your dialog so you can connect/disconnect to a server.
The client will tell you in its OnReceive()[^] handler when more data is available, you can add this to the listbox with AddString()[^] and scroll listbox with SendMessage(WM_VSCROLL, SB_BOTTOM, NULL). There are many ways to communicate between socket and GUI, for starters you could give the socket object a pointer to your dialog. For example with a method OnReceiveText() that you call from your socket whenever a full text line is available:
// Add text to end of listbox and remove old text
void CMyDlg::OnReceiveText(const char* szText)
m_output.SendMessage(WM_VSCROLL, SB_BOTTOM, NULL);
while(m_output.GetCount() > 10000) m_output.DeleteString(0);
I think you have difficulty understanding the purpose of these forums. They are here to help with technical questions, not so someone can provide you with a working solution to order. Reread the guidelines on how to ask a question.
