how to turn off a LED in an array

[altenbach]

From looking at the code, it seem you want to turn it red to show deactivation.

Here's a quick rewrite. Maybe it can give you some ideas. 😄

(also note some of my comments in the other thread)

I think a tab controls is inappropriate for the mode selection. Why not use a radio button for example?

Also, why use a tab control to indicate which mode is selected when a radio button group would seem more intuitive?

EDIT: This is really weird. When I posted my message I did not see altenbach's reply above that had this same question. Then, when I went back into the thread due to an email notification I saw altenbach's reply with the same question I had about using radio buttons, but posted before my question. Weird.

Do you need to have multiple active? ie:  more than one radio button selected?

Hi altenbach

With this problem,at the moment the LED array is in front of the event structure and we got deactivate event is in separate event case.Its working fine

But when i moved the LED array into the Drive select event(because the LED needs to be enabled only after certain conditions) i am able to enable it but when i tried turn OFF (in ur program u have assigned to RED)its not turning OFF,still remaining the enabled colour.

How to turn OFF when moved into the event structure

Thanks

Whatever you are saying is too confusing without seeing the program. Why don't you attach some code again?

[Veeru]

I have attached the code

For time being i am using the tab control

Then don't move it inside the event structure! Why do you break the code by doing random things like that.

Can you tell me why you think you need to move it inside one of the events? Makes no sense!

[Veeru]

becoz in that Drive select event i am using a button so the LED needs to be enabled only after the button is pressed(many case structures in that event)

Thanks

[altenbach]

If it is outside the event as in my original design, it will faithfully display whatever is in the shift register.

If you want a a different output in certain cases, all you need is to manipulate the array going to the shift register accordingly. For example, you can just replace a "black" back into the appropriate location. Right?

Move your Drive Select Array Terminal out of event case 0 "Drive Select Value change".  You may be changing the colors in the array, but they never get passed to the terminal until you change the value in your Drive Select Array.

I still don't understand why when you select a Drive, you disable it in the list.
