How to get any control reference?

Himmet — Fri, 03 Apr 2015 14:28:46 GMT

Hi everyone,

I want to get any control's reference when click the mouse button on any control.(Front Panel includes hundreds of different types of control.) Actually, I found method using "register for event:mouse down value source". This solution is fine working.

But I don't want to use this method. Please Can you suggest any other method ?

Thanks for answer...

There is a property of the front panel of a VI that returns all controls of a front panel. You can register for all controls on a front panel and then the same event will be generated for any control. Drop down a property node of type VI, get the front panel reference, then use another property node to get all controls.

I also made an XNode to help getting references of a specific type, or with a specific label. Say get all controls that start with Boolean.

Be sure and pay attention that XNodes are experimental.

Oh and using the hidden gems you can get a reference to an object based on its label. Using this you could iterate over an array of labels to get.

Using a couple of property nodes, you can get an array of references for all of the controls on a front panel. From there, just register the array.

If your solution is working fine, then why do you not want to use it?

The solution is working fine on Pc. But the solution is not working when this VI(reentrant vi) published for web request on browser( using web publishing tool). You can try it on my example vi(getControlReference.vi). So I need other solution.

Hi Himmet,

I am sorry that you are having trouble with using control references. Can you explain in more detail why the above solutions do not work in your application?
