Instance of an object

[Beengie]

I am getting an "Object reference not set to an instance of an object" error on this code. I have searched the forums, but I cannot seem to find an example that is helping me. I am used to VB6, and trying to understand the basics of .NET

This is in a module, and there is a label on the frmMain called lblTestOutput

Public Sub MakeChanges()
        Dim f As New frmMain
        If f.lblTestOutput.Text = "" Then
            f.lblTestOutput.Text = "Button Pushed!"
        Else
            f.lblTestOutput.Text = ""
        End If
 
    End Sub

Also, I am wondering...

what is the correct way to load up a form using "Sub Main?"

When you started that project, what kind of project did you choose?

I have tried your code and it worked without error, although the app exits almost immediately after it starts (as predicted).

I chose a "Windows Application"

[Beengie]

I added "f.Show" to the code

Option Explicit On 
Option Strict Off
Module mdlTesting
    Private f As New frmMain
    '   Public Sub Main()
    '     Dim g As frmMain
    '     Application.Run(g)
    ' End Sub
    Public Sub MakeChanges()
        If f.lblTestOutput.Text = "" Then
            f.lblTestOutput.Text = "Button Pushed!"
        Else
            f.lblTestOutput.Text = ""
        End If
        Console.WriteLine(f.lblTestOutput.Text)
        f.Show()
    End Sub
End Module

to the module, and now it shows up.
But...
Now I have two forms open now because I had to dimension "f" as "New".
Isn't there a way to reference it without it being "New?"
Or what do I need to do to correct this?
