Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

  Dim nianxian As Integer '年限变量

  Dim dingcun As Integer '定存变量

  Dim fuli_big As Long '大复利

  Dim fuli_small As Long '小复利

  Dim i As Integer '循环变量

  Dim DATAstring As String '数据字符串

  nianxian = Val(年限_TextBox.Text)

  dingcun = Val(定存_TextBox.Text)

  DATAstring = ""

  For i = 1 To nianxian

      fuli_small = dingcun * (1 + 0.1875)

      dingcun = fuli_small

      fuli_big = fuli_big + fuli_small

      DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_big) + Chr(13) + Chr(10)

      'DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_small) + Chr(13) + Chr(10)

  Next

  TextBox1.Text = DATAstring

  结果_TextBox.Text = Str(fuli_big) + "元"

如何用vb.net获得网页的源代码

Dim url As String=" 网址"

Dim httpReq As System.Net.HttpWebRequest

Dim httpResp As System.Net.HttpWebResponse

Dim httpURL As New System.Uri(url)

httpReq.Method = "GET"

httpResp = CType(httpReq.GetResponse(), HttpWebResponse)

httpReq.KeepAlive = False ' 获取或设置一个值，该值指示是否与

Internet资源建立持久连接。
