If you call Access by command line:
create 2 macros to display 2 forms in Access, then use "c:\prog... ...\msaccess.exe" /x macro1|macro2 in Shortcut or bath file
Other way is /cmd as last parameter in command line and form as startup in Access project
As ActiveX Object in LabView:
Open(Access._Application).Forms.Item(Form1).Visible = true ...
Ofcource OpenDB is also required!
