increase button for slide does not work correctly

[cctt126]

Hi everyone,

I want to make a button to increase a slide value according to user's mouse operation:

1. the button pressed less than 0.5 s, the slide increase 1

2. the button pressed more than 0.5 s, the slide increase more

I have done the second function, but I don't know how to realise the first function.

Here is the vi. Please Note, I would like to keep the while loop run all the time.

I appreciated it if someone could help me. Thanks a lot.

Hi cctl,

see attachment: you just need one more decision (before or after delay setpoint)...

And you don't need to convert to string when you want to display hex or octal formatted numbers...

Hi Gred,

Thanks for your kindly help.

I am sorry I did not describe the problem clear enough. 

I hope I just press the 'X++' button for a short while, like 0.5 s (which means the 'Elapsed Time' indicator on the front panel is less than 0.5s), the program could consider that I just pressed the button only once, and then after this button is released, only 1 value add to slider.

Would you please help me, thanks again.

Hi cctt,

you need to check for "events" like "button pressed" and "time elapsed" like shown in the attached VI.

In the long term you better try to use the event structure for handling events...

Hi Gerd,

Great job, thanks. The attached vi looks more closer to what I want.

Actually, I would like to make a button for the slider to instead of the slider's increasement/decreasement button.

Because the slider's increase/decrease button moves too slow when hold press, and the size is too small. So I used the 'X++' button to instead of them.

I really appreciated if more suggestions could give me for design the button.

Thanks a lot.

Hi cctt,

look in the help for "customizing controls". You will even find videos for that topic on the NI.com website...

Yes, you are right, using event structure is a good way to solve this problem.

To help others, I attached a simple example, see attachments.
