如何用VB读取、输出.ini文件

我自己写的一个模块,里面定义了读写两个两函数:

Option Explicit

'定义API函数
'读入INI
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

'写出INI
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 Function GetIniStr(ByVal FileNames As String, ByVal AppName As String, ByVal In_Key As String) As String
On Error GoTo GetIniStrErr
If VBA.Trim(In_Key) = "" Then
GoTo GetIniStrErr
End If
Dim GetStr As String
GetStr = VBA.String(128, 0)

GetPrivateProfileString AppNam
