备忘

昨天在做一个程序的时候需要用到”剪辑板”功能, 可是死活引用不了”windows.forms”… (忘记添加引用了)

无奈只好去找了一个易语言的”置剪辑板文本”, 来翻译.

代码

      /// <summary>
      /// 复制字符串到剪辑板
      /// </summary>
      /// <param name="text"></param>
      /// <returns></returns>
      static bool CopyString(string text)
      {
          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;
      }

      //全局堆栈分配_
      [DllImport("kernel32.dll")]
      static extern int GlobalAlloc(int wFlags, int dwBytes);

      //锁住全局内存块_
      [DllImport("kernel32.dll")]
      static extern int GlobalLock(int hMem);

      //拷贝内存
      [DllImport("kernel32.dll")]
      static extern int RtlMoveMemory(int 目标地址, string 源数据, int 尺寸);

      //解锁全局内存块
      [DllImport("kernel32.dll")]
      static extern int GlobalUnlock(int hMem);

      //清空剪辑板
      [DllImport("user32.dll")]
      static extern int EmptyClipboard();

      //打开剪辑板
      [DllImport("user32.dll")]
      static extern int OpenClipboard(int 剪辑板句柄);

      //设置剪辑板数据
      [DllImport("user32.dll")]
      static extern int SetClipboardData(int wFormat, int hMem);

      //关闭剪辑板
      [DllImport("user32.dll")]
      static extern int CloseClipboard();
