Part selection for subassemblies generation

Experts,
For the API program (2016 SOLIDWORKS API Help - Make Assembly From Selected Components Example (VB.NET)), I want to use this program for other developments but I didn't found how to automatize the selection of the 2 parts (valve<1> and valve_guide<1>).

As the pre-conditons of this program are:

' Preconditions:

' 1. Open install_dir\samples\tutorial\motionstudies\valve_cam2.sldasm

' 2. Ensure that the Save new components to external files check box

'    on the Tools > Options > Assemblies dialog is selected.

'    Otherwise, the selected components are saved as virtual components

'    and not as external files.

' 3. Select valve<1> and valve_guide<1> components.

Can anyone help me and thank you very much.
