求助：关于利用CVI做频谱分析仪提示的一个错误
运行源程序，提示出错：void board(void){
unsigned long type;
unsigned short choice; // User's board device number
GetCtrlVal (panelHandle, PANEL_DEVICE, &choice);

the third and fourth channel. */

小弟还是新手，还请各位大大帮忙解答下是什么问题``感谢
源程序在此：

小弟收集了些关于labwindows的源程序 您这个不是NI的卡吗？如果不是的话就不能用DAQ的，您的错误提示是这样说的！ 它这个程序好像是NI的卡的！ 哦，多谢提醒，小弟原本是想弄成实际信号或仿真信号的都能进行采样，应该如何将程序进行修改？多谢帮忙` 这些资料不错，我收录到精华中，让后面学习的朋友有资料可以学习，非常感谢兄弟！兄弟看看这个第5点！谢谢！
http://www.cpubbs.com/bbs/thread-54347-1-1.html 恩，小弟打算把这个程序改成实际信号或仿真信号的都能进行采样，应该如何将程序进行修改？多谢帮忙` 加一个CHECKBOX，如果是采集的就用函数发生的节点来产生信号！在CVI中没有用过NI的卡，不知道能不能像LV里面一样，可以用DAQ助手一样，可以用虚拟的采集卡，估计应该可以！ 如果有的话就可以更简单了！ 一群SB，就知道把specturm那个例子反反复复发。那例子有问题的
