  /* LPTSTR 转换成 CString */
  
  (1)直接赋值
  CString strText;
  LPTSTR lpszText = _T("LPTSTR >> CString");
  strText = lpszText;
  ::MessageBox( NULL, strText , _T("标题"), MB_ICONASTERISK|MB_TASKMODAL|MB_OK );
  
  (2)CString::Format()格式化
  CString strText;
  LPTSTR lpszText = _T("LPTSTR >> CString");
  strText.Format( _T("%s"), lpszText );
  ::MessageBox( NULL, strText , _T("标题"), MB_ICONASTERISK|MB_TASKMODAL|MB_OK );
  
  /* CString 转换成 LPTSTR */
  
  (1)强制转换
  CString strText( _T("This is a test") );
  LPTSTR lpszText =(LPTSTR)(LPCTSTR)strText;
  ::MessageBox( NULL, lpszText, _T("标题"), MB_ICONASTERISK|MB_TASKMODAL|MB_OK );
  
  (2)使用lstrcpy()
  CString strText( "This is a test" );
  LPTSTR lpszText = new TCHAR[strText.GetLength()+1];
  lstrcpy( lpszText, strText );
  ::MessageBox( NULL, lpszText, _T("标题"), MB_ICONASTERISK|MB_TASKMODAL|MB_OK );
  
  (3)使用CString::GetBuffer()
  CString strText(_T("This is a test "));
  LPTSTR lpszText = strText.GetBuffer();
  strText.ReleaseBuffer();
  ::MessageBox( NULL, lpszText, _T("标题"), MB_ICONASTERISK|MB_TASKMODAL|MB_OK );
  
  /* char * 转换成 CString
  
  char chArray[] = "This is a test";
  char * p = "This is a test";
  
  CString theString = chArray;
  theString.Format(_T("%s"), chArray);
  theString = p;
  
  /* CString转换成char*
  1.
  CString theString( "This is a test" );
  
  LPTSTR lpsz = new TCHAR[theString.GetLength()+1];
  
  _tcscpy(lpsz, theString);
  
  
  2.
  
   CString s(_T("Char test "));
   LPTSTR p = s.GetBuffer();
  
   LPTSTR dot = strchr(p, ''.'');
  
   // 在这里添加使用p的代码
  
   if(p != NULL)
  
   *p = _T('');
   s.ReleaseBuffer();
