C++技巧(寬字符的CString轉(zhuǎn)換為constchar*)

一、
    使用函數(shù)_tcscpy_s：
    CString theString( "This is a test" );
    int sizeOfString = (theString.GetLength() + 1);
    LPTSTR lpsz = new TCHAR[ sizeOfString ];
    _tcscpy_s(lpsz, sizeOfString, theString);
    最后再轉(zhuǎn)換一下lpsz為const型的
    LPTSTR在UNICODE環(huán)境下編譯考試,大提示是whca_t類型
    二、
    CString str = _T("Hello World!");
    char szStr[256] = {0};
    wcstombs(szStr, str, str.GetLength());
    const char * p = szStr;
