How to get this working?

[nemaroller]

The problem is simple...

On your form... in your button click event.... you call Test()...

Which then declares a new form, and disables/enables a button on the new form. By default, the new form's button is enabled, so it disables it.

You see.. you have two forms here... one is instantatied by the IDE when you click RUN (Form1)... the other one is being declared and manipulated in your module1 Class. and that one has a problem though...you haven't set the frm.visible=true

------------------

You should have this in your module:

Module Module1
    Public Sub Main()
        Dim frm As New Form1()
        Application.Run(frm)
 
    End Sub
End Module

And this in your button1_click event:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If Button2.Enabled = False Then
            Button2.Enabled = True
        Else
            Button2.Enabled = False
        End If
    End Sub

And then right-click your project file in the solution explorer window, and set the startup object to Main().
