Express VI - access to POP-UP front panel?

[DonRoth]

Hi:

Some of the express VI pop-up front panels have an excellent layout and would be similar to some of the front panels that I might have to create (see example for wavelet denoise in latest digital filter design toolkit).  Rather than having to recreate one, is there a way to gain access to it as a VI with the existing front panel controls and indicators?



Sincerely,

Don

Hello Don,

I don't see any reason why you can't use shipping components as a template provided they ship without a password.  Most LabVIEW "core" shipping Express VIs are located in [LabVIEW]\vi.lib\express, in various folders roughly matching the palette layout.  The main config page VI is usually the top-level VI in an LLB containing the word "config".  Most of these VIs are not password-protected.

The ones you're referring to are probably going to be located in [LabVIEW]\vi.lib\addons\... for the toolkit that this Express VI ships with.  Hopefully it is easy enough to find from there.  I can't say whether or not the particular Express VI you pictured ships password-protected or not.  If it does, there is probably good reason for it, and you won't be able to use that one for a template.

Another thing that might be a little difficult is that some things on the diagram are Express VI-specific (which you probably don't want), while others are for handling the UI (which you probably do want).

Good luck!

P.S.  Please keep in mind that most of the "core" shipping Express VIs that I referred to initially were created well before LabVIEW 7.0's release, and some haven't been updated much since then, so they might not be the best example of UI handling in today's LabVIEW (a few don't even use the event structure).  I believe the one you referenced is significantly newer, so it's probably pretty good, provided it's not password-protected.

Hi Jeff:

Thanks for your reply.

I found the _WaveletDenoiseConfig.llb in the C:\Program Files\National Instruments\LabVIEW 8.2\vi.lib\addons\Wavelet Analysis\_express directory and it is not password-protected.  It does not use the event structure but it does use the older case-within-while loop state machine structure, which is still not bad.  I may however convert it to event structure.  In any case, I can customize it for my needs - and it gives me a great start without having to start from scratch.

Thanks again,

Don
