轉(zhuǎn)換為 const char*
?
How do I convert from CString
to const char*
in my Unicode MFC application?
推薦答案
要將 TCHAR
CString 轉(zhuǎn)換為 ASCII,請(qǐng)使用 CT2A
宏 - 這也將允許您將字符串轉(zhuǎn)換為 UTF8(或任何其他 Windows 代碼頁):
To convert a TCHAR
CString to ASCII, use the CT2A
macro - this will also allow you to convert the string to UTF8 (or any other Windows code page):
// Convert using the local code page
CString str(_T("Hello, world!"));
CT2A ascii(str);
TRACE(_T("ASCII: %S
"), ascii.m_psz);
// Convert to UTF8
CString str(_T("Some Unicode goodness"));
CT2A ascii(str, CP_UTF8);
TRACE(_T("UTF8: %S
"), ascii.m_psz);
// Convert to Thai code page
CString str(_T("Some Thai text"));
CT2A ascii(str, 874);
TRACE(_T("Thai: %S
"), ascii.m_psz);
還有一個(gè)宏可以從 ASCII -> Unicode (CA2T
) 轉(zhuǎn)換,只要你有 VS2003 或更高版本,你就可以在 ATL/WTL 應(yīng)用程序中使用這些.
There is also a macro to convert from ASCII -> Unicode (CA2T
) and you can use these in ATL/WTL apps as long as you have VS2003 or greater.
有關(guān)詳細(xì)信息,請(qǐng)參閱 MSDN.
See the MSDN for more info.
