Refresh an opened form vb.net

I have my form 1 and when I click in a button it opens my form 2. I want to introduce some information in this second form in order to uptade the first form.
I tried this:
Public class Form2
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
... {some code here}
Form1.Refresh()
Me.Close()
End Sub
End Class
But this isn't refreshing my form1. I know I can close the first form and open it again, but i don't pretend that.
Is there any other way to do this?

What exactly do you think thatRefreshmethod does? It's not going to magically know to get data from a database or from a file or whatever else. Perhaps you should explain whatForm2actually does and what exactly you expect to happen inForm1. My guess is that you have data in a grid inForm1and you making changes to the database inForm2and expectingForm1to reflect those changes. I say that because it's common that beginners do that when it's completely wrong. In that case, you should be making the changes inForm1first, then saving them to the database from there.

If you want to execute some code then you need to execute that code. CallingRefreshis not going to do that and you should not simply assume that it will.

@jmcilhinney yes but how can I execute it from another form?

How do you usually execute code in an object? You call a method.. It has to be a method that actually contains the code you want executed though. Refresh doesn't contain such code so it won't magically execute such code.

Based on the input provided by you, you should fetch the data again from the database in the first form. The refresh method / event handler is different that the Form Load method. You need to call again the method / code responsible for fetching the data from the database.
