Public Function SetActiveAddins( _
   ByRef AddinNames As Variant, _
   Optional ByRef ErrorDescription As Variant _
) As Boolean



An array containing strings specifying the add-in names to load.

The available Add-in names are displayed in the Add-in Manager dialog box. Alternatively, you can use the Addin.Name property to retrieve the relevant add-in name.

ErrorDescriptionIf the set of add-ins you specify contains two or more conflicting add-ins, or if you specify an add-in that is dependent on another add-in that was not included in the specified add-ins list, the ErrorDescription argument stores the error string describing these errors.

Return Type

  • True--The add-ins were loaded successfully.
  • False--UFT One was unable to load the specified set of add-ins.


  • In addition to using this method to load add-ins provided with UFT One, you can also use it to load add-ins that you or a third party developed  using add-in extensibility to provide UFT One support for additional environments or controls.
  • If an add-in is displayed in the Add-in Manager dialog box as a child of another add-in, and you instruct UFT One to load the child add-in, UFT One also loads the parent add-in. 
  • The Add-ins specified in this method are loaded instead of any add-ins loaded previously.
  • Add-ins loaded using this method are not unloaded dynamically when the test ends.
