c#   谢谢了  我再看看   

我想做的事情就是模仿记事本  在文本编辑框里  移动鼠标 或键盘移动光标  能再状态栏里显示当前的行 列 值

现在鼠标的能做到了  主键盘输入也能做到了  但是 方向键的移动却是实现不了

   嗯  还真是那么回事   以后再研究了  （暂时有点看不懂  呵呵）

private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            int EM_LINEFROMCHAR = 0xC9;
            int Row = (int)SendMessage(textBox1.Handle, EM_LINEFROMCHAR, -1, 0) + 1;
            int j = (int)SendMessage(textBox1.Handle, 0xB0, 0, 0) / 65536;
            int k = (int)SendMessage(textBox1.Handle, 0xBB, -1, 0);
            int m = j - k + 1;
            this.toolStripStatusLabel1.Text = "当前光标:" + Row + "行" + " " + m + "列";

        }

        private void textBox1_KeyUp(object sender, KeyEventArgs e)
        {
            int EM_LINEFROMCHAR = 0xC9;
            int Row = (int)SendMessage(textBox1.Handle, EM_LINEFROMCHAR, -1, 0) + 1;
            int j = (int)SendMessage(textBox1.Handle, 0xB0, 0, 0) / 65536;
            int k = (int)SendMessage(textBox1.Handle, 0xBB, -1, 0);
            int m = j - k + 1;
            this.toolStripStatusLabel1.Text = "当前光标:" + Row + "行" + " " + m + "列";

        }

也没啥心得了   把这2个事件都写上  就实现 目标了  可以用方向键移动位置的同时   状态栏的行列位置也跟随改变
