求助
我现在在做一个检测面板，图片在附件里，这个面板是虚拟信号输入面板，还有个检测面板没有做出来，不过现在遇到的问题是两个面板之间的连接转换，我试了很多次都不成功，很郁闷，希望高手同志帮忙指点下！谢谢在有个问题，我这有三个通道，我的想法是输入三个信号传到下一个检测面板进行检测，希望各位帮我看看，能否实现，因为我第二个面板还没做出来。最好有程序给我研究下！谢谢

} 两个面板之间的连接转换也许可以这样(仅供参考):
先把两个面板都装入(在MAIN函数里),先只显示信号输入面板,当按下"检测"按钮时,将信号输入面板隐藏,显示检测面板.关闭检测面板(其实只是隐藏)时,再将信号输入面板显示(DISPLAY)出来...
