Get Multiple Combo box contents from single external INI file

I am trying to learn SW API from help files and Sample macros from this forum.

Here is a sample macro with an external INI file that populates one combo box (Material for example)

Can someone please help me to modify this macro with simple code to get multiple combo boxes to work from same INI file

I need to add other properties to this macro later.

Thanks
