str.FormatエラーBuffer too small
The call will fail if the string object itself is offered as a parameter to Format. For example, the following code will cause unpredictable results:

CAtlString str = _T("Some Data");
str.Format(_T("%s%d"), str, 123);   
// Attention: str is also used in the parameter list.
