求助！急！谢谢

我现在在用LabWindow做一个虚拟设备，结果遇到了很多问题。
我要做的是对信号的检测虚拟软件，现在已经把虚拟信号调试完了，但是面板之间转换按键却转换不了，老是有问题！再就是虚拟出来的信号要在检测面板用7个灯来显示的检测结果，如果检测过程中在某个地方有信号不符合要求的话，相应的灯就会熄灭，然后检测停止，接下来的灯也就是熄灭的。可是我总是想不通，编不出来！麻烦各位高手了，帮小弟费心了！最好有程序给我研究下！在这里先谢谢拉！

你最好能把代码贴出来看看，这样说，不太清楚你的目的。

还有就是，我在一个窗口里面有两个面板，但是只有一个面板的程序，请问怎么生成另一个面板的程序呢？而且是把两个程序加在一起的那种？

sjm12 发表于 2007-5-19 21:38:55

用installpopup()函数安装你的检测面板（即灯显示面板).在原先产生信号的函数后面，添加点亮灯的函数即可。然后在该面板的关闭函数中用removepopup（）函数即可转回原先的面板（控制信号面板）。不知答复是否满意？

我想在select里面有三个选项，在点start之后，如果选在第一个选项就是前3个灯亮。要是第二个选项就是最后两个灯亮，如果是第三个选项就是是前5个灯亮。可以帮我实现么？感激不尽......谢谢

对你的描述不是很明白，抱歉，帮不上什么忙啊！呵呵

fuucc 发表于 2007-5-22 07:47:55

select是个旋转开关，通过旋转来实现不同的灯亮。然后一按start就开始亮灯了
明白么？:) 嘿嘿
在帮帮忙看看吧？

}

break;

前面板有一个旋转开关（三种状态）。同时有七个状态灯和一个按钮。
上述回答不知可以吗？
