将字符串添加到Visual Basic窗体

如何向Visual Basic窗体添加字符串?

我正在为自己创建一个学习应用程序,这就是我所拥有的:

Imports System.Diagnostics
Public Class Form1

Dim amounts As Integer


Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Processes.Tick
    Dim proc() As Process = Process.GetProcesses
    Dim newproc As New Process
    amounts = 0
    For Each newproc In proc
        If newproc.ProcessName = "firefox" Then
            newproc.Kill()
            amounts = +1

        Else

        End If
    Next
End Sub

Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click

End Sub

结束类

我正试图在我的表单上显示一行文本,并说……阻止火狐运行x次。

x是我的“数量”变量。

我的表格是这样的: http://img696.imageshack.us/img696/8162/programq.png

那么,我怎样才能用我的数量变量来代替x呢?
