Things have been said already. So in addition, if you are programing
with MFC, simply:

CString strRem( _T("PM_REMOVE") );

And get in the habit of using the _T macro. TCHAR without it doesn't
make any sense. I said it again as this will pay off later. My fingers
automatically do it any more.

LOGFONT NewFontLogStruct;
if ( StringCchCopy( ( TCHAR* )&NewFontLogStruct.lfFaceName, sizeof ( NewFontLogStruct.lfFaceName), "Courier New" ) == S_OK);
{ //rest of program execution if the above StringCchCopy went ok }

You should have gotten a warning about that semicolon at the end of your
if(...); Compile with warnings cranked all the way up.

You should very rarely, and only if you really know better:
#pragma warning(disable : xxxx)

The call can simply be:
StringCchCopy( lf.lfFaceName, LF_FACESIZE, _T("Courier New") );

lfFaceName will be sized according to build as there is a LOGFONTW and a
LOGFONTA.
