wxString字串轉換

char*、TCHAR*、wxString三種字串轉換
char*->TCHAR*

char *ansii_string = "some text";

int size = strlen(ansii_string);

TCHAR unicode_string[30];

mbstowcs(unicode_string, ansii_string, size+1);

TCHAR*->char*

TCHAR* unicode_string=_T("unicode string");

int size= wcslen(unicode_string);

char ansi_string[30];

wcstombs(ansi_string, unicode_string, size+1);

wxString->char*

wxString wx_string=_T("wx string");

char ansi_string[30];

strcpy(ansi_string,wx_string.mb_str());

char*->wxString

char *ansii_string = "some text";

wxString wx_string(ansii_string,wxConvUTF8);

wxString->TCHAR*

wxString wx_string=_T("wx string");

TCHAR wchar_string[30];

wcscpy(wchar_string,wx_string.wc_str());

TCHAR*->wxString

TCHAR *tchar_string = _T("some text");

wxString wx_string(tchar_string,wxConvUTF8);
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
wxString::operator <<

wxString& operator <<(const wxString& str)

wxString& operator <<(const char* psz)

wxString& operator <<(char ch)

Same as +=.

wxString& operator <<(int i)

wxString& operator <<(float f)

wxString& operator <<(double d)

These functions work as C++ stream insertion operators: they insert the given value into the string. Precision or format cannot be set using them, you can use Printf for this.
