            UInt32 count = SendMessage(h, TCM_GETITEMCOUNT, 0, 0);

            Console.WriteLine("共有 " + count + " 个分页");



            UInt32 index = SendMessage(h, TCM_GETCURSEL, 0, 0);

            Console.WriteLine("当前选中第 " + (index + 1) + " 页");



            if (index == 0)

            {

                index = count - 1;

            }

            else

            {

                index = 0;

            }



            SendMessage(h, TCM_SETCURSEL, index, 0);

            Console.WriteLine("已跳转到 " + (index + 1) + " 页");



            Console.ReadKey();

        }

    }

}

非常简单

这里有个帖子
然后你可以在需要切换tab页的界面调用切换页面事件模拟传入参数。定义一个变量或者判断sender参数是否为空在事件里面判断然后判断是否执行该方法

这些问题我已经解决了，已经实现了跨进程选择TabControl的当前页，不过发送了TCM_SETCURSEL消息后，Tabcontrol的标题确实有变化，不过TabPage的内容并没有变，我再用ShowWindow显示一下对应的Tabpage试试看

[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);

或者

[DllImport("user32.dll", ExactSpelling=true, CharSet=CharSet.Auto)]
public static extern IntPtr GetParent(IntPtr hWnd);

TabPage的句柄怎么取出来的?难道不用先取出TabControl句柄才能取TabPage句柄?
