Unusual problem with application

Solved!
Go to solution

Hi labview-community,

I will try to explain my problem as simple as possible.

My application contains only 1 string control, 1 time control, 1 numeric control in 1 while loop refresh every 250ms(no events, no other controls) .

When I try to open .exe everything is ok, I can modify the value inside the string control.

The problem occurs when I click somewhere around app(desktop for example), at the moment application stops to react. Wherever I click in the app it doesnt react at all, but works( i can see the increasing value of timer control)....

It happens only in 1 computer station(DELL, Win7 x64), but unfortunately this one is the computer of the service guy.

There is no errors during working, it just doesnt react when someone wants to enter data to string control/ numeric control/ actually any kind.

I tried with other applications wrote by me, and all of them have the same behaviour in this 1 station. User is not able to enter data after click around app, after minimalize it etc..

I assume the problem is outside Labview but no guarantee. Installed all libraries.

Anyone had a similar problem?

 

Thanks for any help.

If the application itself works, you have everything installed which is required for it.

From the description i understand that

as soon as the application looses the focus (active app) in Windows, the issue occurs.

 

Does that happen with other applications (e.g. Word) as well?

 

I recommend you to double check Windows configuration settings (e.g. running services) and configuration/involvment of anti-virus software and firewall.

If possible, reinstall that machine with a new image of a working system.

As you wrote, focus doesnt work correctly. I tried to set focus on string control - no reaction.

 

Does that happen with other applications (e.g. Word) as well?

No problems with others

 

I recommend you to double check Windows configuration settings (e.g. running services) and configuration/involvment of anti-virus software and firewall.

I will verify all of it, thank you for the advice.

 

I noticed 1 interesting thing:

- I am not able to update numeric control "by hand" - enter digit in control field

- I am able to update numeric control by using increment/decrement pointers(next to control)

So it seems that the issue is evolving around keyboard interaction. Mouse interaction works correctly all the time, right?

This is indeed very strange, but i am still confident that it is connected to some system specific configurations.

Ok I have done it, but I dont quite understand the core of the problem.

I had to change Window behaviour from default to float, it solved the problem.

But the reason why it didnt work correctly is not understandable for me. I assume some OS settings difference between computers created problems with focus.
