CSTRING LPCTSTR LPTSTR Type of Transformation

CSTRING LPCTSTR LPTSTR type mutual conversion // 変 number definition LPTSTR S_T; LPCTSTR S_C; CSTRING STR; CSTRING SRESULT; const I_CT = 5; INT i = 10; const * p_ct = & i_ct; int * p = & i;

// メ メ ド ド 1. CString -> LPTSTR

// Initialization す す S_T = "null"; s_ct = "null"; str = "secbug"; // 変 S_T = (lptstr) (LPCTSTR) STR;

/ / The result is す

SResult = CString ("Turn CString から LPTSTR, OK:") S_T;

MessageBox (SResult);

// メ メ ド ド 2. CSTRING -> LPCTSTR

// Initialization S_T = "null"; s_ct = "null"; str = "secbug"; // 変 す S_CT = STR;

/ / The result SResult = CString ("Turn CString から lpctstr, OK:") S_CT; MessageBox (SRESULT);

// メ メ ド ド 3. LPCTSTR -> LPTSTR

// Initialization S_T = "NULL"; s_ct = "null"; str = "secbug"; // 変 す S_CT = Str; // s_t = s_ct; // error, The Same with p = p_ct;

/ / The result SRESULT = CString ("Turn LPCTSTR から LPTSTR, NG"); MessageBox (SRESULT);

// メ メ ド ド 4. LPTSTR -> LPCTSTR

// Initialization S_T = "sec"; s_ct = "bug"; str = "secbug"; // 変 す す S_CT = S_T; // Wright, The Same with p_ct = P;

/ / The result is SRESULT = CSTRING ("Turn LPTSTR から LPCTSTR, OK") S_CT; MessageBox (SRESULT);
