我有一個代碼來獲取硬盤製造序列號，它總是適合我... 但是從Delphi 7到Delphi 2010的版本，此代碼doesn'工作了。 當然，我認爲由DELPHI版本支持的UNICODE和ANSI之間的區別原因。 但現在，轉換爲德爾福2010年是很難我... 如果你有這樣的代碼示例，在DELPHI的Unicode支持版本的作品， 或者可以修改我的代碼可以輕鬆地使用DELPHI Unicode版本，請給我幫忙。 。 感謝閱讀我的文章... 下面是我的原代碼，在DELPHI 7DELPHI：HardDisk unequal製造序列號源代碼修改

問題是什麼？將所有'Char'類型更改爲'AnsiChar'，將所有'String'類型更改爲'AnsiString'，'PChar'更改爲'PAnsiChar'，並且Unicode不是問題。 –
你說過嗎？我認爲你很容易說話。我已經像你說過的那樣嘗試過了，但仍然存在問題......理解？ – fangrenxing
你說沒有提到嘗試任何東西。如果您已經嘗試過，但它不起作用，您需要準確告訴我們您嘗試的是什麼，以及哪些結果不起作用。理解？堆棧溢出不是代碼寫入或轉換服務。 @KenWhite只是基於我們可以看到的解決方案來回答你的問題。你已經知道這是一個unicode問題，並且有很多文檔解釋如何去做這個轉變。 –
