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)

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点虐 读取ini的所有值
Dim s As String() = System.IO.File.ReadAllLines("t.ini") '文件
For i As Integer = 0 To s.Length - 1
Dim si As Integer = s(i).IndexOf("=")
If si -1 Then
ListBox1.Items.Add(s(i).Substring(0, si) " = " s(i).Substring(si + 1))
End If
Next
's(i).Substring(0, si)是变量名，s(i).Substring(si + 1)是值
VB点虐 2005中到底怎么读取ini文件
用API吧
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
'读
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
'写
Public Function WriteINI(ByVal Section As String, ByVal AppName As String, ByVal WriteString As String, ByVal FileName As String) As Long
WriteINI = WritePrivateProfileString(Section, AppName, WriteString, FileName)
End Function
其中，Section是像[ip]那样的（填里面的就可以了），AppName是“=”前面的项名称，lpDefault是如果没有可用的值，就返回lpDefault，FileName是文件名，WriteString是要写入的值
你所希望的：
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MsgBox(GetINI("ip", "user_id", "", "D:\DataBase.ini"))
'返回sa
End Sub
vb点虐 读写ini文件问题
以下是我的办法:OK!
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 Integer, ByVal lpFileName As String) As Integer
Public Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal lpString As String, ByVal lpFileName As String) As Integer
写:
WritePrivateProfileString("存储", "账号", textbox1, Application.StartupPath "\song.ini")
读:
dim s as string
s = string(255," ")
GetPrivateProfileString("存储", "账号", s, s.Length, Application.StartupPath + "\song.ini")
textbox1 =s
