all combo box are blocked when vi is running

[larson09]

Hi!!

I have a problem with my VI.....when it's running all the combo box are blocked and i can't change them value using the mouse....i don't know why!!

What can i do to solve this problem without copying all the block diagram into a new VI??

Thank you very much.

Can you post your code here?

are you sure you didn't create Combo Box indicators?

Also, right-click on the Combo Box and choose Advanced > Enabled State and make sure you don't have them "Disabled".  Furthermore, make sure you don't have Property Nodes for the Combo Boxes in your code somewhere that are setting their state to Disabled.

Hello!

All the combo box control are enabled.

I explain better what it happens in my VI. The combo boc aren't blocked......i can see the items of each one but when i select one of them the combo box doesn't change.....the value is blocked.

I don't understand...I press on the combo box and i see the list of each one but when i select one of them the value doesn't change...always the value is the same that when you start running the VI.

I've copied the block diagram to a new one and the problem continues.

What can I do?

Thanks!!!

I'm guessing you've got a local variable or property node that is programmatically changing the value of the Combo Box after you have changed it in the UI.  Or perhaps it's a screen updating issue.  I would search for locals and property nodes of the combo box and figure out where you're writing its value, and make sure you don't have a race condition.

If you can reproduce the problem in a simple VI, you should post it so we can take a better look at the issue.

Hello again!

I've searche all property nodes and local variables and i haven't find any place where the value of the combo box is changed..this is not the problem.

I don't understand what t means "Or perhaps it's a screen updating issue".

This vi was build in labview 7.0 and now i'm using it in labview 7.1....this iin't problem, is it?

Thank you for helping me

Yeah, at this point I'm out of suggestions.  There's really nothing else I can think of other than for you to narrow the problem down to a simple VI and post it so we can take a look.

Good luck,
