Right-click an ActiveX automation refnum control and select Select ActiveX Class»Browse from the shortcut menu to display this dialog box.

Use this dialog box to call an ActiveX object from LabVIEW or select an ActiveX Server class.

This dialog box includes the following components:

  • Type Library—Displays the type libraries available on the computer. The type libraries in the list are not the ActiveX implementations, but metadata files that explain what type libraries the ActiveX component uses.
    Note  You can store type libraries in a shared library (DLL) or an executable (EXE). When you browse to the DLL or an EXE, you are browsing to the type library.
  • Objects—Displays the objects available in the type library you select. This list displays only the ActiveX objects installed and registered with the operating system.
  • Show Creatable Objects Only—Causes the Objects listbox to display only creatable objects.

    COM/ActiveX utilizes interfaces, not classes. You can specify which implementation you want for the interface. Selecting Show Creatable Objects Only displays all implementations that are available. The object you select is the implementation of the interface while the object shown in the LabVIEW block diagram is the interface itself. If you do not select Show Creatable Objects Only, LabVIEW displays both the implementations and the interfaces.
