【vb.net】求个用VS2013读写INI的代码

vb.net有自己的设置，不需要ini，在工程【属性】-【设置】中设置。

ini设置属性。

'声明API函数

Private Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal lpString As String, ByVal lpFileName As String) As Int32

Public Function WriteINI(ByVal Section As String, ByVal AppName As String, ByVal lpDefault As String, ByVal FileName As String) As Long

Return WritePrivateProfileString(Section, AppName, lpDefault, FileName)

End Function

‘调用writeini函数存储属性。

‘section为节点，也就是ini中带[]符号的节点文本

’APPname为存储的名称，即ini文件中等于符号前面的文本

’ipdefault为存储的属性，即等于符号右边的文本。

‘filename为存储的ini文件地址，如d:\save.ini

————————

ini返回属性。

'声明API函数

Private 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

Private Function GetINI(ByVal Section As String, ByVal AppName As String, ByVal lpDefault As String, ByVal FileName As String) As String

Dim Str As String = ""

Str = LSet(Str, IniCount)

GetPrivateProfileString(Section, AppName, lpDefault, Str, Len(Str), FileName)

Return Microsoft.VisualBasic.Left(Str, InStr(Str, Chr(0)) - 1)

End Function

’调用getini函数

‘说明同上。

VB.NET做的一个行业小软件，请问如何加密，比如需要通过什么硬件的序列号注册；

最好的加密就是通过你的网站去加密！用网络服务器验证把一些主要程序都可以加载到服务器上！这样你的程序加密就完美了！　（个人观点纯属不懂装懂的。哈哈见笑）

求大神指点 vb.net 怎么读 ini 配置呢

VB.NET读写INI配置文件

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

Dim path As String

path = Application.StartupPath + "\Send.ini"

TextBox1.Text = GetINI("Send", "Send1", "", path)

TextBox2.Text = GetINI("Send", "Send2", "", path)

Dim IsSms As Integer = GetINI("Send", "IsSms", "", path)

If (IsSms = 1) Then

Me.RadioButton1.Checked = True

ElseIf (IsSms = 0) Then

Me.RadioButton2.Checked = True

End If

End Sub

Public Function GetINI(ByVal Section As String, ByVal AppName As String, ByVal lpDefault As String, ByVal FileName As String) As String

Dim Str As String = LSet(Str, 256)

GetPrivateProfileString(Section, AppName, lpDefault, Str, Len(Str), FileName)

Return Microsoft.VisualBasic.Left(Str, InStr(Str, Chr(0)) - 1)

End Function

Public Function WriteINI(ByVal Section As String, ByVal AppName As String, ByVal lpDefault As String, ByVal FileName As String) As Long

WriteINI = WritePrivateProfileString(Section, AppName, lpDefault, FileName)

End Function

Private 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

Private Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal lpString As String, ByVal lpFileName As String) As Int32

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

Try

Dim path As String

path = Application.StartupPath + "\Send.ini"

WriteINI("Send", "Send1", TextBox1.Text, path)

WriteINI("Send", "Send2", TextBox2.Text, path)

If (Me.RadioButton1.Checked = True) Then

WriteINI("Send", "IsSms", 1, path)

ElseIf (Me.RadioButton2.Checked = True) Then

WriteINI("Send", "IsSms", 0, path)

End If

MsgBox("配置设置已经成功！！！！")

Catch ex As Exception

MsgBox("错误！！！！")

End Try

End Sub

VB.NET开发的软件，大家一般都是怎么加密的

网上有很多专业的加密教程

最适合小开发者的软件加密方式就是下面这个

获取硬件信息和个人注册时的姓名手机号等一系列信息，通过预先设定好的加密函数进行散列加密，生成一个只有本人本机能使用的序列号，软件正版授权的时候用同样的方式生成序列号进行比对，一样则通过

用.net实现文件夹加密
