MSDN says:

CFile::modeCreate
Directs the constructor to create a new file. If the file exists already, it is truncated to 0 length

CStdioFile file;
<font color="blue">if</font> (file.Open(_T(<font color="blue">"\\log.txt"</font>), CFile::modeCreate | CFile::modeWrite | CFile::modeNoTruncate)) {
    <font color="green">//file.Seek(0, CFile::end);</font>
    file.SeekToEnd();
    file.WriteString(logfile);
    file.WriteString(_T(<font color="blue">"\n"</font>));
    file.Close();
}

file.Seek(CFile::end)

file.Seek(0,CFile::end)

this is not right and right one is this
file.Seek(0,CFile::end)

For windows, I plan to use WPF and for LINUX and MAC someother opensource UI framework.

For writting the core engine, which compiler should I use?

And is it possible to use the Visual Studio editor even if I am not using MFC/C++ CLI?

Rajesh R Subramanian wrote:

On Windows, you may use Visual C++ (Yes, visual studio).

I plan to use the borland compiler and use VS as editor.

After completing it, I need to compile it for each platform, right?

Christian Flutcher wrote:

Do you know that compiler allows to create a DLL for that class in windows?

Christian Flutcher wrote:

Thanks for taking time to help me. Your replies were really helpful. Thanks again Smile

Rajesh R Subramanian wrote:

Is there a specific reason to it? If you are using the VS, then why not use the Visual C++ compiler itself?

Christian Flutcher wrote:

Okay. So I shoud not use any MFC classes. Use plain C++ classes for it, right?

Christian Flutcher wrote:

But this class should compile with other compilers which are in LINUX and MAC. So I think, using VC++ compiler won't allow me to compile the same code on other platforms.

Rajesh R Subramanian wrote:

write plain and portable C++ code, which is standards-conformant and that should compile on any standard C++ compiler. Hope that helps

BTW, all these C++ things are bit confusing compared to C#, isn't it?
