Vb.Net Menu

Hi Experts

I Have a menu Structure
Click on drop down and it runs a program
see following code
I need to finish the first program then automatically run the second
not run the second until the first is completed
I know I can run from first program newprogram on close or save events
but need to return to menu to check other variables before running 2nd program newprogram2

Private sub newprogram_click(ByValue sender as tObject,ByVal e As Enventargs)_
handles newprogram.Click

dim newprog as new newprogram()
newprog.show()

dim newprog2 as new newporgram2()
newprog2.show()

End sub

The show() methods must be blocking. Otherwise it's not possible.

btw, what are your "program" classes doing? show sounds like simple windows. Here we have the built-in option of modal windows:

- Displaying Modal and Modeless Windows Forms

Or use the chain of responsibility pattern with a null or result collecting object.
