Here is a pretty simple one. When you push the button the input from the Arduino shows up in the immediate window. just make a form with a button

Public Class Form1
    
    Public readstr As String
    Function getCom() As String
        readstr = ""

        If SerialPort1.IsOpen = True Then
            SerialPort1.Close()
            SerialPort1.Open()
            readstr = SerialPort1.ReadLine
            Debug.Print(readstr)
            getCom = readstr
        End If
    End Function
    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        SerialPort1.BaudRate = 9600
        SerialPort1.Parity = 0
        SerialPort1.StopBits = IO.Ports.StopBits.One
        SerialPort1.DataBits = 8
        SerialPort1.PortName = "com7"
        SerialPort1.Open()
    End Sub

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
       dim bob as string
       bob = Me.getCom()
        Debug.Print(bob)
       'put your code to translate to an integer here
    End Sub


End Class
