Vanishing custom button images?

[Mitsurugi]

No joy on the PNG thing. Will let you know how the strictly typed setting works out. Cheers.

[Mitsurugi]

No, I'm afraid the Strictly setting didn't make a difference either. 😞

Hi Mitsurugi,

I'm currently running your code and unfortunately I haven't experienced the same issue you saw yet.

However I did notice on your block diagram that you lack timing in your while loop. I'd recommend that you insert a "Wait until next ms Multiple" function from the Functions-> Programming-> Timing palette with a constant such as 10 into your loop. This provides time for the processor to rest. If the disappearance is actually caused by your graphics card being 'maxed out' then this timing may also help to solve this issue.

Hope this helps and I will keep your code running to see if I can also observe the problem,

Hmmm.  It didn't disappear on me after setting it to strictly typed.  Perhaps I didn't wait long enough.  Tori.M has a good suggestion.  I didn't notice your lack of timing in the while loop.  As a matter of efficiency and good practice, regardless of your application, you should include a wait in your while loop, unless it's already built in, so as not to over-tax the processor.

Hi again MoReese & Mitsurugi,

After replicating your error and seeing that it still occurred with timing in the loop, I remade your code including both the VI and buttons.

These don't seem to disappear (correct me if you observe the same problem) which suggests that either the buttons or the VI was corrupted in your code.

Make a new project and add them in and have a look

Hope this fixes everything!!

[Mitsurugi]

Thanks for that, I'll check it out.

Hiya Tori. I wouldn't think it was the VI itself that was playing up, because there are a host of other custom buttons on the app we're building and none of them are affected in the same way my buttons are. Definitely something about the way my buttons were built I'm thinking. Anyway, thanks for the code you uploaded. Got it on screen now waiting to see if the problem still persists. Quick question though, when you were creating your buttons, what TYPE of button did you use (push button, rocker, slide switch, toggle switch, etc)....?

Hi Mitsurugi,

In the zip file, the controls I remade are also included. You can customise most of the controls, but I just used a Boolean Stop with the mechanical action "latch when pressed".

Couple of other things I did, but are unlikely to have caused the issue:

I converted your images to .png format - although GIFs are usable, PNGs are generally preferable. As suggested by MoReese, I also used Type Def controls.

Fingers crossed the code being remade has managed to tackle the problem!

[Tori.M]

Hi Mitsurugi,

Just wondering if the new VI and custom controls fixed the "disappearing" issue that you were having?

Let me know!

[Mitsurugi]

Hullo Tori.

The answer to your question is Yes AND No.

The buttons you sent over worked great....but when I tried to replicate what you did (mechanical action, file type, and all that) I still got the same blank buttons. In a last ditch effort I tried making a copy of your buttons, and modifying those, but that only resulted in the same outcome.

I've no idea what I'm doing different to you guys, and I don't know what else to try.

If only they'd let us drink in the office, y'know? 😞

Anyway, some more questions:

- regarding the images, did you do anything other than change the file extension from .gif to .png?

- when you allocated the .png to a given button's picture items, what method do you use: "import from file" or "import from clipboard"?

- any major difference or advantages between the two methods?

Thanks.

Mitsurugi.
