National Instruments recommends using front panel data binding through the Shared Variable Engine or using the Bind To Network Path method to attach a data connection to a control.

This method allows you to attach an opc, ftp, and http connection to a control on Windows, and a dstp and file connection to a control on all LabVIEW-supported platforms. You can add new connections only at edit time.

This method is similar to the Data Binding Selection, Path, and Access Type options on the Data Binding page of the Properties dialog box.

Note If you use this method with a Boolean control in a radio buttons control, this method returns an error.
