『急』C# 有关鼠标转化问题（左右键切换问题）

Question

请问一下：
        本人在做一个小项目：现有一支蓝牙笔（笔上有一个按键）以及一个显示屏。
        功能是：使蓝牙笔能当左右鼠标使用。        现遇到一个问题，现通过按键能单独实现左，右键；但当右键按下后，一直为右键菜单，不能响应左键事件。
        代码如下：         //for firing mouse and keyboard events

    请问高手指点，谢谢啦！

看代码，这东西是不是按下比如按下按钮后蓝牙发送鼠标动作给电脑，按住就是移动，放开移动停止？
你好像吧原来定义为左键操作改成了右键，但这里好像没改掉
  buffer1[0].type = INPUT_MOUSE; 
                    buffer1[0].mi.dx = 0; 
                    buffer1[0].mi.dy = 0; 
                    buffer1[0].mi.mouseData = 0; 
                    buffer1[0].mi.time = 0;                     { 
                    //  MessageBox.Show("Right"); 
                        buffer1[0].mi.dwFlags = MOUSEEVENTF_RIGHTUP;                     } 
                  
                    buffer1[0].mi.dwExtraInfo = (IntPtr)0; 
                    SendInput(1, buffer1, Marshal.SizeOf(buffer1[0]));
