XControl: automatic update

Hello

Is there an easy way to tell LabView to regularly call the structure of an XControl of the event? In my scenario the XControl should query the data (for example every 250ms) and update its display. In a normal VI with a structure of the event, I'd do polling in the event of delay, but it will not work in an XControl.

A complicated to make this automatic updating would be an extra VI that periodically calls a function of the XControl to force an update - but I would have preferred an XControl operating without such assistance VI.

Best regards.

My experience with XControls is limited, so I do not have a direct answer, but you can at least hide the problem of the user of the control in asynchronous mode launched the VI yourself inside the XControl initializing it and appellant to stop it when uniniting. I don't know how it worked in development time if you remove the XControl of the FP. If she does not call the uninit method when you remove it, you will find yourself with a few screws red, but how many times you delete the XControl?
