front panel is frozes

[Vardan]

Hello,

I have front panel froze problem in my vi.

My vi contains Activex control and DAQ.

 In vi properties I have to choose execution mode

"user interface" because otherwise my activex control do not communicate with external device.

At all other modes there is no front panel frozen problem. Is there a known solution?

Thank you in advance

This is just a wild guess, but do you have loops?  Do you have any wait in the loops?  Do you have multiple loops that can run in parallel?

The above was just a wild guess.

Actually, is it possible for you to post the code and we can have a look at it.

Thanks,

RayR

Hello RayR,

Thanks for your replay.

Here is the code.

Please pay attantion that it is not frozen. It will be frozen as you  try

to move it.

Thanks

Hi Vardan,

I downloaded your file, but the arrow is broken to start with.
I am unable to load your Motion Control

Sorry

[Vardan]

Hello,

Thank you for downloading the vi.

I think this is due to drivers which are missing in your computer.
The motion control is thorlabs ATP motion controls.

It has simulation regime.

I do not know what can be done in this situation. Excuse me for
inconvenience.

Best wishes

Hi Vardan,

      Here's your code - cleaned-up a bit.  I think RayR may be on to something re:loops - note that until "Start" is pressed, the main loop is "free-running".

(you probably want to add a delay in the False case...):smileywink:

Cheers!

(Amazingly, the cleanup button in LabVIEW 8.6 does about the same thing. :D)

The loops are not the problem, you problem is the priority setting at "time critical priority(highest) ". Set this back to "normal" and thing will improve. 😄

A VI set to time critical will focus mostly on code and will postpone any UI features, thus your VI seems frozen when you run it.

(Also your "delay values" does not do anything, since you don't use the output)

I wish I could see what you mean, but alas, my LV version # is smaller than yours.

(sigh)

It actually works amazingly well here, but of course it does not remove obsolete stuff, such as the sequence structure.

Here's the before (top) and after(bottom) picture. All I did was load the VI and press cleanup. What a time saver! 😄
