excel - Opening a diffrent Macro-Enabled workbook from VBA code, security issues -

so, have program writing (in parent workbook). in program need open .xlsm file (child),although not need run macros immediately. problem way security setting work means when try pop-up shown in (http://www.sigmaxl.com/images/helpdesk/sw1.jpg).

i using basic workbooks.open method, , have application.displayalerts = false. there way can disable security message code in parent workbook? not allowed change security settings.

unfortunately problem, there isn't way change macro security settings vba. if place child book in location excel considers safe, open & run it.
