This is the INIRead File I name it INIRead.bas
Here is the Code:
Option Explicit
 
Public Function ReadIniValue(INIpath As String, KEY As String, Variable As String) As String

    Open INIpath For Binary As NF
    Close NF
    'SetAttr INIpath, vbArchive
 
LoadFile:
    Open INIpath For Input As NF
    While Not EOF(NF)
    Line Input #NF, temp
    LcaseTemp = LCase$(temp)
    If InStr(LcaseTemp, "[") <> 0 Then ReadyToRead = False
    If LcaseTemp = KEY Then ReadyToRead = True
    If InStr(LcaseTemp, "[") = 0 And ReadyToRead = True Then
        If InStr(LcaseTemp, Variable & "=") = 1 Then
            ReadIniValue = Mid$(temp, 1 + Len(Variable & "="))
            Close NF: Exit Function
            End If
        End If
    Wend
    Close NF
