備忘

昨天在做一個程式的時候需要用到”剪輯板”功能, 可是死活引用不了”windows.forms”… (忘記新增引用了)

無奈只好去找了一個易語言的”置剪輯板文字”, 來翻譯.

程式碼

      /// 複製字串到剪輯板

      /// <param name="text"></param>
      /// <returns></returns>

      {
          int
 
 DwLength = text.Length+1;
          int GHND = 2;
          int hGlobalMemory = GlobalAlloc(GHND, DwLength);
          int lpGlobalMemory = GlobalLock(hGlobalMemory);

          RtlMoveMemory(lpGlobalMemory, text, DwLength);
          GlobalUnlock(hGlobalMemory);

          int hWnd=0;
          OpenClipboard(hWnd);
          EmptyClipboard();

          const
 
 int CF_TEXT = 1;
          bool i;
          if (SetClipboardData(CF_TEXT, hGlobalMemory) != 0)
          {
              i = true;
          }
          else
          {
              i = false;
          }
          CloseClipboard();
          return i;
