Marquee Progress Bar in LabVIEW

[Hesloppy]

Hi Thoric,

This was reported to R&D (#109450) for further investigation.  I added your workaround to the CAR information.

Best Regards,

Great, thanks Bryan.

Hi all.  Nice work.

Does anyone know how to get the .NET progress bar to work in a For loop?

[battler.]

I don't mean with the marquee.  I mean with the Value progress.

I tried combining the .NET progress with Darren's nugget progress (attached).

Hi battler,

I wonder if your attachment is missing the subvi in the for loop? Or is it somewhere else on these forums? (I don't have it on my system)

[Thoric]

battler,

I've found that missing subvi by reading your message more carefully!

I modified it to use a .NET progress bar in a .NET container. It initialises the .NET control upon first requirement, then closes it on the last iteration.

It needs a little bit of work still to get to look quite right (for some reason it ends before it reaches 100% full, but I think it might be to do with update rates running a little slow).

Use it in your loop (in place of Darren's subvi).

I created it in LV2009 and exported it for LV8.0, but not tested the 8.0 version.

Good luck!

Thanks very much Thoric.

I looked into why the bar was never reaching 100%.  It does appear to be an update delay.

To fix this (not the best solution) I added a delay before the VI terminates to allow the progress bar to reach 100%.  It works.

A question: Will this NET instance of the progress bar be compatible with any operating system (once I deploy as exe?  Will the end user need to have the latest NET framework or anything like this?

Cheers,

Battler.

Nice work on the delay.

I think this .NET instance is .NET 2.0, so the user will need at least that revision on their PC. If it is not present, I think a whole world of hurt can open up (error messages at launch regarding an inexecutable vi). Best to test this, rather than take my word for it !

Hello Everybody,

I used the latest example of marquee for For-loops and it works nice only once! After calling it for a second time, the marquee window pops up but the marquee is from the beginning and stay at 100%, no matter of the for-loop iteration until last for loop iteration has been acheved, then the marquee window closes normaly. What should i do in order to get the marquee bar growing even after the second call of it?

First call - everytrhing works fine:

Second call - Marquee is 100% from the beginnng until the end:

Source - how i call it:

Hope somebody can halp,

Thank you
