Short Name: WebSrvr.VIAccess

Requires: Base Development System

Class: Application Properties

To Use: Create a property.

Sets or gets the VIs that are visible through the Web Server. This property also sets or gets whether LabVIEW allows access to each VI.

This property is an array of strings, where each string is a VI name that begins with + or -. If you specify a non-default control time limit for a VI, the value appears before +.

  • + specifies that LabVIEW allows access to the VI.
  • - specifies that LabVIEW does not allow access to the VI.
Note  You can use this property to limit access to clones already in memory for remote front panel connections. Limiting access to clones is useful when you have a limited number of resources. To limit the number of clones created for remote front panel connections, use the Open VI Reference function to create the required number of clones. Use the VI Clone Name property to get the name of each clone. Limit the access to only those clones you created by adding each clone name beginning with + to the array and by adding the name of the original reentrant VI beginning with - to the array.

This property is similar to the Web Server page of the Options dialog box.
