自从注册表诞生以来ini文件正在逐渐失去其市场占有率，然而基于ini文件的独立性，致使其还没有到达退出历史舞台的地步，很多应用程序的初始化和一些界面参数的设置仍然很愿意从ini文件中读取，为了保证操作需用参数对ini文件的读取的通明性，建议使用一个模块来完成此工作。注：所有操作调用标准的Win API函数来完成。
Dim Ret As Long
Dim Start As Long
Public FileName As String
Const BufSize = 10240
Dim buf As String * BufSize
Private Declare Function GetPrivateProfileInt Lib "kernel32" Alias "GetPrivateProfileIntA" (ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal nDefault As Long, ByVal lpFileName As String) As Long
Private Declare Function GetPrivateProfileSection Lib "kernel32" Alias "GetPrivateProfileSectionA" (ByVal lpAppName As String, ByVal lpReturnedString As String, ByVal nSize As Long, 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 Declare Function WritePrivateProfileSection Lib "kernel32" Alias "WritePrivateProfileSectionA" (ByVal lpAppName As String, ByVal lpString As String, ByVal lpFileName As String) As Long
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
Public Sub SetValue(ByVal clsName As String, ByVal key As String, ByVal V As String)
Ret = WritePrivateProfileString(clsName, key, V, FileName)
End Sub
Public Function GetValue(ByVal clsName As String, ByVal key As String) As String
Ret = GetPrivateProfileString(clsName, key, "", buf, BufSize, FileName)
Start = 1
GetValue = RetStr()
End Function
Private Function RetStr() As String
Dim i As Long
i = InStr(Start, buf, Chr(0))
If i > Start Then
RetStr = Mid(buf, Start, i - Start)
End If
Start = i + 1
End Function
至此已经完成了对一个完整的独立模块的封装，接下来就来看看怎么引用（其实看完上面程序就明了了），
