Take a picture of a sub vi with a not opend frontpanel

[DrBigred]

Hello,

I try to take a picture of a frontpanel.

This works fine if the Frontpanel is opend.

But this shall appear in a sub vi and I dont want to open the frontpanel of that sub vi.

So I get, with the frontpanel closed, only a picture without values and other mistakes.

How can I manage this?

Thans for yopur help!

Regards

Have you tried the Get Panel Image method? You can take the result and save it to a JPG or BMP file.

Yes, with this method i get the picture.

If the frontpanel is open, its fine.

But if the frontpanel is not opend, it is garblet.

And I dont want the frontpanel to pop up while running this sub vi.

Thanks for help!

What version of LV?

Could you post screen shots of the good and bad versions?

In additon to Ben's request, I'd like to see exactly how you are using the get image method.

Im using the latest version of LV, LV 8.2.

The Attachement "getpic" is how I get the picture.

"emailpicgood" is what I get with open frontpanel.

"emailpicbad" is what I get with closed frondpanel (bad picture).

Regards

LV 8.2.1 is now available.

Could you try a quick test?

Try doing an invoke node "Get Image" for just one of the controls prior to doing the "Get image" of the panels to see if that helps.

One other thing to check: If there is not one there already try putting a property node for a front panel control on the block diagram of the VI that you are getting the image of. There is a very old bug that keeps poppingup from time to time that the front panel is not displayed or updated properly if its not loaded into memory. Putting a property node on the block diagram forces LV to load front panels into memory, even if they aren't displayed.

The property node doesn't have to do anything useful. For example, it could set a control that's already visible to be visible, or enable a control that's already enabled.

Place the two vi's in a  folder and run Image.vi

@mikeporter: I aleready do changes in the frontpanel before making the picture.

@Ben: Sorry I did not get what you talking. Could you please explain for poor english dummies?

Thanks!
