yinengsoft 的 LPTSTR CString 相互转换

/* 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 );
