I agree with Joe. I actually search my files periodically to see if there
are any "char" things anywhere I need to replace since force of habit
occasionally sees me typing one in that I miss. I would just use TCHAR or
the _T or LPCTSTR or, better yet, as Ali suggested, get used to using
CStrings for these sorts of things. The overhead is minimal and it morphs
itself into the most amazing places with hardly any trouble.

I am trying to do a simple operation, open a file and write to it. In my
view
class I added code which I copied from the MSDN site and modified it for
my
purposes but here's what it looks like.

char* pszFileName = "c:\\test\\myfile.txt";
CFile myFile;
CFileException fileException;

if ( !myFile.Open( pszFileName, CFile::modeCreate |
         CFile::modeReadWrite, &fileException ) )
{
   TRACE( "Can't open file %s, error = %u\n",
      pszFileName, fileException.m_cause );
}

when I try to build I get an error that Open cannot convert pszFileName
from
char* to LPCTSTR. When I cast pszFileName to LPCTSTR it builds
successfully
but the file ends up being created in

C:\Documents and Settings\<myuser>\My Documents\Visual Studio
2005\Projects\<my project> instead of in C:\test\. Further, the file has a
weird name that looks like chinese or japanese and it's not even in text
format. Does anyone know what it happening. I am using VS 2005.
