用VB.NET開(kāi)發(fā)的應(yīng)用程序，大家用什么軟件或第三方控件做UI界面的編碼?。?/h2>

Visual Studio?2013

成都創(chuàng)新互聯(lián)長(zhǎng)期為數(shù)千家客戶提供的網(wǎng)站建設(shè)服務(wù)，團(tuán)隊(duì)從業(yè)經(jīng)驗(yàn)10年，關(guān)注不同地域、不同群體，并針對(duì)不同對(duì)象提供差異化的產(chǎn)品和服務(wù)；打造開(kāi)放共贏平臺(tái)，與合作伙伴共同營(yíng)造健康的互聯(lián)網(wǎng)生態(tài)環(huán)境。為永清企業(yè)提供專(zhuān)業(yè)的成都網(wǎng)站建設(shè)、做網(wǎng)站，永清網(wǎng)站改版等技術(shù)服務(wù)。擁有10年豐富建站經(jīng)驗(yàn)和眾多成功案例,為您定制開(kāi)發(fā)。

Microsoft Visual Studio（簡(jiǎn)稱(chēng)VS）是美國(guó)微軟公司的開(kāi)發(fā)工具包系列產(chǎn)品。VS是一個(gè)基本完整的開(kāi)發(fā)工具集，它包括了整個(gè)軟件生命周期中所需要的大部分工具，如UML工具、代碼管控工具、集成開(kāi)發(fā)環(huán)境(IDE)等等。所寫(xiě)的目標(biāo)代碼適用于微軟支持的所有平臺(tái)，包括Microsoft Windows、Windows Mobile、Windows CE、.NET Framework、.NET Compact Framework和Microsoft?Silverlight?及Windows Phone。?Visual Studio是目前最流行的Windows平臺(tái)應(yīng)用程序的集成開(kāi)發(fā)環(huán)境。最新版本為 Visual Studio 2013 版本，基于.NET Framework?4.5.1 。

求vb.net的源代碼，最好說(shuō)明其解決問(wèn)題，越多越好，滿意加50分。

下面這段代碼，是我用來(lái)計(jì)算每個(gè)月存500元進(jìn)銀行，連續(xù)30年，最后連本帶利能有多少錢(qián)。這里面涉及復(fù)利計(jì)算。界面中右邊的文本框用來(lái)輸出每一次計(jì)算的結(jié)果。

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

? Dim nianxian As Integer '年限變量

? Dim dingcun As Integer '定存變量

? Dim fuli_big As Long '大復(fù)利

? Dim fuli_small As Long '小復(fù)利

? Dim i As Integer '循環(huán)變量

? Dim DATAstring As String '數(shù)據(jù)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

? 結(jié)果_TextBox.Text = Str(fuli_big) + "元"

End Sub

在vb.net中怎么調(diào)用自定義類(lèi)？

代碼已測(cè)試。

一、測(cè)試需要的INI文件。名稱(chēng)為“setinfo.ini”，存放路徑為你解決方案里“Bin“文件夾的”Debug“文件夾里。

內(nèi)容：

[Location]

pnlTime.Location.X=787

pnlTime.Location.Y=0

[TopMost]

Top=True

二、操作INI文件的類(lèi)。新建一個(gè)類(lèi)，類(lèi)中內(nèi)容為：

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、界面代碼：

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?開(kāi)辟存儲(chǔ)的內(nèi)存

myBf?=?New?String(CChar(""),?256)

Dim?myFN?As?String?'配置文件的文件路徑

myFN?=?Path.Combine(My.Application.Info.DirectoryPath,?"setinfo.ini")

Dim?myAN?As?String?'Application_NAME,也是Section名稱(chēng)

myAN?=?Me.TextBox1.Text

Dim?myKN?As?String?'KEY_NAME,關(guān)鍵字名稱(chēng)

myKN?=?Me.TextBox2.Text

Class1.GetPrivateProfileString(myAN,?myKN,?"",?myBf,?myBf.Length,?myFN)?'調(diào)用讀取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

四、測(cè)試截圖如下
