請問各位先進： 我想將一串IP宣告成wchar_t的型態，是否要以下列的形式宣告才行： wchar_t DeviceAddress[11]={'1','9','2','.','1','6','8','.','1','.','3'}; 我試過其他的宣告都不行，這是唯一的宣告形式嗎？

應該有簡單的可行方法，不過我不清楚 但你可以先用這種方式..     AnsiString a("192.168.1.1"); wchar_t *w=new wchar_t[a.WideCharBufSize() 1]; a.WideChar(w, a.WideCharBufSize()); .... delete [] w;

WideString DeviceAddress="192.168.1.3"; 這樣不知道符不符合你的要求阿?? WideString represents strings of 16-bit characters (wchar_t). As such, it is useful when working with COM. WideString values are easily converted to or from BSTR values. WideString also supports sharing the value of an existing BSTR. The C class WideString is functionally equivalent to an Object Pascal intrinsic type, also called WideString.

引言: WideString DeviceAddress="192.168.1.3"; 這樣不知道符不符合你的要求阿?? WideString represents strings of 16-bit characters (wchar_t). As such, it is useful when working with COM.

謝謝你，這樣可以用了， 可是我還是有一點不懂， 因為我有import 一個VC 寫的OCX， 其中一個method的參數所需的type即為wchar_t， 但如果我以我上面所說或是依照justdo大大所說的宣告， 雖然可以compile，但是在執行時都會有很奇怪的錯誤發生， 這三種宣告方式難道不一樣嗎？

wchar_t 字符的宣告方式要用 L'' wchar_t 字串的宣告方式要用 L""    EX:

wchar_t wc=L'我';
wchar_t wc1=L'\x0041';          // == L'A'
wchar_t wstr[]=L"三二一";
wchar_t wstr1[]=L"A\x0042"L"C"; // == L"ABC"

Compiler 會自動將字串轉成 Unicode 格式。
