【VB源码推荐：一个操作Ini文件的类】
'--------cIniFile.cls 代码----------------
'这里定义了一个cIniFile类
Option Explicit
'// Private member that holds a reference to
'// the path of our ini file
Private strInI As String
'// Win API Declares
Private Declare Function WritePrivateProfileString _
Lib "kernel32" Alias "WritePrivateProfileStringA" _
(ByVal lpApplicationName As String, _
ByVal lpKeyName As Any, _
ByVal lpString As Any, _
ByVal lpFileName As String) As Long
Private Declare Function GetPrivateProfileString _
Lib "kernel32" Alias "GetPrivateProfileStringA" _
(ByVal lpApplicationName As String, _
ByVal lpKeyName As Any, _
ByVal lpDefault As String, _
ByVal lpReturnedString As String, _
ByVal nSize As Long, _
ByVal lpFileName As String) As Long
Private Function MakePath(ByVal strDrv As String, _
ByVal strDir As String) As String
'// Makes an INI file: Guarantees a sub dir
Do While Right$(strDrv, 1) = "\"
strDrv = Left$(strDrv, Len(strDrv) - 1)
Loop
Do While Left$(strDir, 1) = "\"
strDir = Mid$(strDir, 2)
Loop
'// Return the path
MakePath = strDrv & "\" & strDir
End Function
Public Sub CreateIni(strDrv As String, strDir As String)
'// Make a new ini file
strInI = MakePath(strDrv, strDir)
End Sub
Public Sub WriteFile(strSection As String, _
strKey As String, _
strValue As String)
'// Write to strINI
WritePrivateProfileString strSection, _
strKey, strValue, strInI
End Sub
Public Function GetFile(strSection As String, _
strKey As String) As String
Dim strTmp As String
Dim lngRet As String
strTmp = String$(100, Chr(32))
lngRet = GetPrivateProfileString(strSection, _
strKey, "", strTmp, _

GetFile = strTmp
End Function
Public Property Let INIFile(ByVal New_IniPath As String)
'// Sets the new ini path
strInI = New_IniPath
End Property
Public Property Get INIFile() As String
'// Returns the current ini path
INIFile = strInI
End Property
'--------cIniFile.cls 使用举例----------------
Dim myIniFile As New cIniFile
'---指定访问的ini文件
If Len(App.Path) > 3 Then
'under disk root dir , eg: "C:\"
myIniFile.INIFile = App.Path & "\setting.ini"
Else
myIniFile.INIFile = App.Path & "setting.ini"
End If
'---写入ini文件
myIniFile.WriteFile "setting", "username", strUser
'---读出ini文件的数据
' 注意，如果是字符串，则去掉末尾一个字符
' [email protected]
strUser = Trim(myIniFile.GetFile("setting", "username"))
strUser = Left(strUser, Len(strUser) - 1)
