A carriage return is \r. A line feed is \n. A CRLF pair is \r\n. This has nothing to do with CString.

Hi,
I have the following wrapper to FormatMessage that helps the caller not worry about freeing the memory required for the error description string. This works great for me, but I would like to know this can be extended to using in multiple threads too. Any comments and ideas? Thanks in advance.

<br />
_TCHAR *error_string (DWORD errCode)<br />
{<br />
    static _TCHAR szMsgBuf[4096];    <br />
    _TCHAR *pMsgBuf = (_TCHAR *)szMsgBuf;<br />
    DWORD result;<br />
<br />
    ZeroMemory(szMsgBuf, sizeof(szMsgBuf));<br />
<br />
    result = FormatMessage( FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS,<br />
                            NULL, <br />
                            errCode, <br />
                            MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language<br />
                            pMsgBuf, <br />
                            sizeof(szMsgBuf), <br />
                            NULL );<br />
<br />
    if (result == NULL) return NULL;<br />
<br />
    return pMsgBuf;    <br />
}<br />

As built, you would need to use thread local storage. So in general, I would change your solution to return something such as a managed string if you can.

I'm going to patent thought. I have yet to see any prior art.

oh, i was just saying this because you asked this question few days ago...

i also posted to you some links that "i thought" they were answering your request...

moreover, you have a [delete] link at the bottom of your posts if you wrote one twice.

however, is this[^] and this[^] satisfying you ??? if not, search CodeProject for Charting Controls[^]...

You can also find online help here[^]

For your problem, if you don't give us more details (errors you encounter, if these are compile errors or crashes, ...), we won't be able to help you (nobody here can read what's on your screen Smile | :)

). Just one question: are you using an application with MFC (Microsoft Fundation Classes) ? Otherwise, this won't work because the controls on this website use the MFC (and I suppose in Borland, they are not available).

From MSDN online help:

"The Microsoft Developer Network (MSDN) is a set of online and offline services designed to help developers write applications using Microsoft products and technologies..."

It's normally added to your PC when you intall Visual Studio but if you can't install it you can find it at http://msdn.microsoft.com/[^].

Particullary, for VC++ and MFC[^]
