Dera Paulo,
Let me explain clearly..1st thing, When I click a figure(actually I set it as button, but I hide it), I want a dialog box appear as a menu selection, eg:-there are 2 types of machine..A and B.Then, when I click A..a new window(window A) will appear. My second problem is, How to connect the button in main vi to subvi?I hope it should be clear for you. Please show me the simple example because i'm so stupid in LV :headbang:
Regards,
Roxe
