CString类GetBuffer 用法

CString m_strApplicationPath；

LPTSTR lpszBuffer = m_strApplicationPath.GetBuffer(_MAX_PATH);

GetModuleFileName(NULL, lpszBuffer, _MAX_PATH);

_tcsrchr(lpszBuffer, _T('\\'))[0] = 0;

lpszBuffer = _tcsrchr(lpszBuffer, _T('\\'));

if(lpszBuffer)

*lpszBuffer = 0;

m_strApplicationPath.ReleaseBuffer();

//以上程序运行完毕后m_strApplicationPath里面就是当前模块所在路径。
