在LabVIEW界面设计的风水中讲到容错性，请教一下大家采用什么方式实现“失效"避免用户误操作的。

That's also called "idiot-proved"...

Examples including but not limited to...

• Set range for a numeric input control for Voltage Control to prevent user from keying/ entering Voltage level that could cause damage to a PCB when it is being powered up.
• Enable/ disable Enum/ Ring items for a given mode.
• Many more....

There isn't fixed way of achieving such but depending on how user-friendly and "idiot-proved" you want to achieve on your particular software panel(s).

假如我的测试系统在运行的时候，不希望用户对硬件设置等对监测有影响的面板进行误操作，当打开设置面板的时候，使确定等按钮变灰，再次请教一下应该如何实现这类在主面板运行时子面板不能设置确定按钮变灰等类容错。谢谢。

Take a Boolean Control (Button) for example...

You may create a Property Node: Disabled for the control, set it to 0 to enable, 1 or 2 to disable the control.

For more information, you may read the context help for that property.
