If you are using the above code, and the text dissapears when you use SetSel(...), it might be due to the fact that your call to SetSel is incorrect, and is selecting the entire control. Then, the base CEdit::OnChar(...) gets called, which will replace the selection with whatever character was entered (a CR or LF); the result: no text in the control.
Also, in the above code, "nLines" is not initialized. That might result in some strange scrolling effects.
Lastly, if all you want to do is add a CRLF and some text to an edit control, the easiest (and faster than the code you posted) is to do a CEdit::SetSel(...) to get to the end of the control, and then call CEdit::ReplaceSel(...) with the text you want to add to the control. And since pasting normally moves the caret to the end of the pastes text, you will still be at the end of the edit control's text.
Peace!

Ah, right you are.
It works if I remove the selection afterwards, naturally.
Thank you for the help, much appreciated!

Hi!
How can I create a tab control like the ones used in VC++, Office, Homesite etc. for switching documents. It's upside-down and the selected one is generally in white. 
Thanks

You can also check http://www.codeproject.com/editctrl/enhfocusedit.asp. Not meant to be a self-plug, but I really do not see the need for (1) a potential dynamic memory allocation whenever a paint cycle happens, or (2) the need to draw the text yourself...
You can just handle the correct messages, and let Windows do all of the work for you. Functions of interest in the code are CFocusEditCtrl::CtlColor(...) and CFocusEditCtrl::OnEraseBkgnd(...). The code also handles Disabled and Read-Only edit controls.

Season greetings to all  .
In my MFC-app I have a logon-dialog that presents the user with a list-box to select between (hardcoded) odbc-connections.
My question is: Is there a way to list the defined obdc-connections in this list-box instead of whichever is hard-coded?

How would I get the list of offline and online users into list boxes in my program if I wanted to make an MSN messanger client with more features than what MSN has at the moment?
Are there any resources people can tell me about using the MSN commands like Block Sender, etc etc??
Thanks

How do I tell at runtime if am in an sdi/mdi or dlg app?
i.e are there some #defines I can use.
If so - what are they?
-cheb

I wonder why you thought it was an easy question
Anyway first do this
AfxGetMainWnd
to get a pointer to the main window
now call this function on the CWnd* returned
GetRuntimeClass
you'll get the class name using the m_lpszClassName member
now use IsDerivedFrom and pass the CRuntimeClass* for CDialog, CFrameWnd and CMDIFrameWnd till one of them matches
got it?
Nish
p.s. I haven't tried it out yet, so there might be somethin I missed...

Sounds good.
I thought it would be easy as I assumed that there would be #defines buried in MFC some where for sure.
I just did not know where.
Anyway, thanks this is a good robust solution.

I don't know if there are any #defines, but you might try:
AfxGetMainWnd()->IsKindOf( RUNTIME_CLASS(CDialog) );
AfxGetMainWnd()->IsKindOf( RUNTIME_CLASS(CFrameWnd) );
AfxGetMainWnd()->IsKindOf( RUNTIME_CLASS(CMDIFrameWnd) );
I haven't, though, given this a try, so I can't guarantee it will work.

Hello!!
I am building a TAPI application in which there is one server and many clients.i.e. N client machines would be connecting and communicating with 1 server machine. Once the connection is established, server would be accepting the data sent by the clients and then the same data would be again sent back to the same client who sent it to the server, through modem. The application should have the capability to do data transmission and receive simulnateously with n-clients.
The application is supposed to run on Win 98,WinNT, WIN 2000 and Win XP. I am using C programming and TAPI 2.0. I do not want to use COM/DCOM. Can you please tell me if it is possible to build an application of n-clients and 1 server using language C, TAPI 2.0 and without COM/DCOM.
I already have built an application for data communication between single client and single server.
Data transmission is done through the COM port to which the modem is connected.
Can anyone please help and advise as to how I could go on to build a n-client 1 server TAPI application.
Any help would be higly appreciated.
Thanks

I am trying to do this:
...
CString strMsg;
...
char *pBuffer = new char[nLen+1];
...
strcpy(pBuffer,(const char*)strMsg);
...
I get error C2440: 'type cast' : cannot conver from 'class CString' to 'const char *'.....
How do I get this to work?
Thanks

If you're using UNICODE, then why not use a TCHAR instead of a char?
CString strMsg = _T("Test me");
TCHAR *pBuffer = new TCHAR[100];
_tcscpy(pBuffer, (LPCTSTR) strMsg);
cout << pBuffer << endl;

I assume you're doing this in a Unicode build? CString holds TCHARs, so in your case it's got WCHARs (wide characters, a.k.a. Unicode chars), and CString has no facility for converting between character sets.
Use one of ATL's conversion macros:
USES_CONVERSION;
strcpy ( pBuffer, T2CA((LPCTSTR) strMsg) ); T2CA() converts from a TCHAR string (Unicode string in Unicode builds) to a const ANSI string.
