Re : how to initialize x control to default value

[LV_user1]

Hi all

I have developed the X control in which I have one knob and 1 numeric control.

It is working fine. But when my VI stops , for next run i want my x control to get initialize to default value.

Right now it shows the last values.

How should I initialize X control to default values?

Do i need to do something with the init ctl of X control??

Hi,

I think its not possible to directly initialize the X control to its default value using its property. But you can initialize its value during each run in the X Control itself. You can set the value of each control in the "Exec State Change" event. I have attached an example XControl which has a knob and a numeric control. Have a look at it,

The XCtrl Init ability is only run when a VI is loaded into memory (aka, when you open the VI). Resetting the XCtrl to a default value depends on what you actually want to reset :

- Specific controls from within the XCtrl : follow Citra's post

- The "real" data of the XCrtl : from a local variable or property node from the calling VI. You still can use the aforementioned method for this one (make sure you set the Data Changed flag to True).

Hi,

you might create a property or method for your XCtrl. Then you would call that at the start of your VI...
