【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, _
Len(strTmp), strInI)

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
´ ----flybird@chinaasp.com
strUser = Trim(myIniFile.GetFile("setting", "username"))
strUser = Left(strUser, Len(strUser) - 1)
