"sub vi calling main vi"

[hema]

I have a main menu calling several submenus using button functions. When i enter the submenu it should close main menu. Then how do i come back to the main menu after closing the submenu?

You can use a VI reference to close and then reopen the front panel of your main menu vi. The attached example has a one button "menu". When you click the button, it closes the mainmenu front panel (not the VI, just its front panel), and runs a vi for the submenu. It waits for the subVI to get done, then it reopens the mainmenu front panel.
