求vb.net的源代码,最好说明其解决问题,越多越好,满意加50分。

下面这段代码,是我用来计算每个月存500元进银行,连续30年,最后连本带利能有多少钱。这里面涉及复利计算。界面中右边的文本框用来输出每一次计算的结果。

  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)-vb.net源码

      Next

      'fuli_big = fuli_small

      TextBox1.Text = DATAstring

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

  End Sub

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 = CType(WebRequest.Create(httpURL), HttpWebRequest)

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。

Dim reader As StreamReader = _

New StreamReader(httpResp.GetResponseStream,

System.Text.Encoding.GetEncoding(-0))

Dim respHTML As String = reader.ReadToEnd() 'respHTML就是网页源代码

vb.net中如何利用api函数获取网页源代码???

Dim MyClient As WebClient = New WebClient

Dim MyReader As New System.IO.StreamReader(MyClient.OpenRead(url), System.Text.Encoding.Default) '定义新的文件流并读取网页文件数据,url表示需要打开的网页地址-vb.net源码

Dim longTxt As String = MyReader.ReadToEnd 'longtxt存储了网页的源码

MyReader.Close()

vb.net源代码如何生成exe格式

vb.net编译出来的exe只有依赖.net

framework才能运行

但有一些第三方工具可以用来把exe用到的assembly和dll打包成一个exe文件,不过这样的结果就是exe体积非常大

比如.netz工具,它的官方地址:

使用很简单,比如你的exe文件是a.exe,直接netz

a.exe就可以把a和它用到的.net代码一起打包成一个exe
