Close 2 Forms on Exit

If FormA if startup form, then you can write Me.Close() or End in FormA to close all forms.

you have to keep the reference to the other form, and close that.

formA is not a startup form nor a parent

>Ive got a formA that has a button that fires another form
that means that formA is the "parent" of the other one...
I guess a confusion of terms here.

As formA fires the other form, it should have/retain that form's reference. and using that, it can close it also at any time.

Bit late but you can lop through the My.Application.OpenForms and close them fromt he main form.
