用VB.NET开发的应用程序，大家用什么软件或第三方控件做UI界面的编码啊？
Visual Studio 2013

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)
Next
'fuli_big = fuli_small
TextBox1.Text = DATAstring
结果_TextBox.Text = Str(fuli_big) + "元"
End Sub
在vb.net中怎么调用自定义类？
代码已测试。
一、测试需要的INI文件。名称为“setinfo.ini”，存放路径为你解决方案里“Bin“文件夹的”Debug“文件夹里。
内容：
[Location]
pnlTime.Location.X=787
pnlTime.Location.Y=0
[TopMost]
Top=True
二、操作INI文件的类。新建一个类，类中内容为：
Public Class Class1
Public Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" _
( _
ByVal lpApplicationName As String, _
ByVal lpKeyName As String, _
ByVal lpDefault As String, _
ByVal lpReturnedString As String, _
ByVal nSize As Int32, _
ByVal lpFileName As String _
) As Int32
End Class
三、界面代码：
Imports System.IO 'for path
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
getINI()
End Sub
Private Sub getINI()
Dim iniclass As New Class1 '
Dim myBf As String 'get set_info 开辟存储的内存
myBf = New String(CChar(""), 256)
Dim myFN As String '配置文件的文件路径
myFN = Path.Combine(My.Application.Info.DirectoryPath, "setinfo.ini")
Dim myAN As String 'Application_NAME,也是Section名称
myAN = Me.TextBox1.Text
Dim myKN As String 'KEY_NAME,关键字名称
myKN = Me.TextBox2.Text
Class1.GetPrivateProfileString(myAN, myKN, "", myBf, myBf.Length, myFN) '调用读取INI文件的操作
TextBox3.Text = Microsoft.VisualBasic.Left(myBf, InStr(myBf, Chr(0)) - 1) '截取有用部分,有必要
End Sub
End Class
