But your purpose is to replace the c with r, you can use the Replace function..
CString cstr = "abcd"; cstr.Replace( 'c','r');nave [OpenedFileFinder]

CString cstr = _T("abcd");
cstr.SetAt(2, _T('r'));If you insist on using GetBuffer(), remember: "If you use the pointer returned by GetBuffer to change the string contents, you must call ReleaseBuffer ..."
CString cstr = _T("abcd");
LPTSTR p = cstr.GetBuffer();
p[2] = _T('r');
cstr.ReleaseBuffer();Mark

Does it take a boolean parameter too?

Actually it does, however it is optional:
PXSTR PlzGetBuf(BOOL bUrgent = TRUE);
