Can I using a VB program to trigger the excel file to run a macro for
some other updates?

Yes, you can. You need to define an object in the VB program and bind it
to the Excel type library.

Dim objExcel as Object

Set objExcel = New Excel.Application

Then in your code use

objExcel.Run("<Macro Name", [<arg_1,...,<arg_n]) to cause Excel to
trigger the macro (if that syntax doesn't work, try
objExcel.Application.Run...I can't remember which one is correct).

In VBA, simply use Application.Run("<Macro Name", [<arg1,...,<arg_n]

HTH.
