You can use the Process class to determine what processes are running. I suggest a bit of reading.

try this one.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim pro() As Process = Process.GetProcesses
        For Each p As Process In pro
            If p.ProcessName = "calc" Then
                MessageBox.Show("The calculator was running")
            End If
        Next
    End Sub
