Cara Membaca & Menulis INI File Vb6

Sumber : http://arifsoftgames.blogspot.com/2013/02/cara-membaca-menulis-ini-file-vb6.html

Pasti ada orang bertanya-tanya bagaimana menggunakan file INI untuk VB6???, nah Pada kesempatan ini saya akan memberikan cara untuk membaca dan menulis INI File pada VB6. Semoga membantu :)





Bahan - Bahan :
1. Visual Basic 6, kalo belom punya pake yang portable gak apa-apa. Download disini | Password : arifsoftgames
2. Kesabaran

Caranya :
1. Tambahkan 3 TextBox, 1 Timer dan 1 Command Button

Saya Menyusun Seperti ini.

2. Buat 2 Module
Module 1 kasih nama : Read
Module 2 kasih nama : Write

Klik kanan, pilih Add lalu klik Module

Sekarang Tahap Codingnya :

Klik 2x pada daerah form 1 dan masukkan code ini :

'Coding Form

Private Sub Command1_Click()

End

End Sub

Private Sub Form_Load()

Text1.Text = ReadIniValue(App.Path & "\INFO.ini", "Default", "Text1")

    Text2.Text = ReadIniValue(App.Path & "\INFO.ini", "Default", "Text2")

    Text3.Text = ReadIniValue(App.Path & "\INFO.ini", "Default", "Text3")

    Timer1.Enabled = True

End Sub

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)

    If UnloadMode = 0 Then Cancel = 1

End Sub

Private Sub Timer1_Timer()

WriteIniValue App.Path & "\INFO.ini", "Default", "Text1", Text1.Text

    WriteIniValue App.Path & "\INFO.ini", "Default", "Text2", Text2.Text

    WriteIniValue App.Path & "\INFO.ini", "Default", "Text3", Text3.Text

End Sub

Pada Module 1 / Read masukkan Code ini

'Fungsi Module Read

Option Explicit

Public Function ReadIniValue(INIpath As String, KEY As String, Variable As String) As String

Dim NF As Integer

Dim Temp As String

Dim LcaseTemp As String

Dim ReadyToRead As Boolean

    

AssignVariables:

        NF = FreeFile

        ReadIniValue = ""

        KEY = "[" & LCase$(KEY) & "]"

        Variable = LCase$(Variable)

    

EnsureFileExists:

    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

End Function

Pada Module 2 / Write masukkan Code ini :

'Fungsi Module Write

Option Explicit

Public Function WriteIniValue(INIpath As String, PutKey As String, PutVariable As String, PutValue As String)

Dim Temp As String

Dim LcaseTemp As String

Dim ReadKey As String

Dim ReadVariable As String

Dim LOKEY As Integer

Dim HIKEY As Integer

Dim KEYLEN As Integer

Dim VAR As Integer

Dim VARENDOFLINE As Integer

Dim NF As Integer

Dim X As Integer

AssignVariables:

    NF = FreeFile

    ReadKey = vbCrLf & "[" & LCase$(PutKey) & "]" & Chr$(13)

    KEYLEN = Len(ReadKey)

    ReadVariable = Chr$(10) & LCase$(PutVariable) & "="

        

EnsureFileExists:

    Open INIpath For Binary As NF

    Close NF

    SetAttr INIpath, vbArchive

    

LoadFile:

    Open INIpath For Input As NF

    Temp = Input$(LOF(NF), NF)

    Temp = vbCrLf & Temp & "[]"

    Close NF

    LcaseTemp = LCase$(Temp)

    

LogicMenu:

    LOKEY = InStr(LcaseTemp, ReadKey)

    If LOKEY = 0 Then GoTo AddKey:

    HIKEY = InStr(LOKEY + KEYLEN, LcaseTemp, "[")

    VAR = InStr(LOKEY, LcaseTemp, ReadVariable)

    If VAR > HIKEY Or VAR < LOKEY Then GoTo AddVariable:

    GoTo RenewVariable:

    

AddKey:

        Temp = Left$(Temp, Len(Temp) - 2)

        Temp = Temp & vbCrLf & vbCrLf & "[" & PutKey & "]" & vbCrLf & PutVariable & "=" & PutValue

        GoTo TrimFinalString:

        

AddVariable:

        Temp = Left$(Temp, Len(Temp) - 2)

        Temp = Left$(Temp, LOKEY + KEYLEN) & PutVariable & "=" & PutValue & vbCrLf & Mid$(Temp, LOKEY + KEYLEN + 1)

        GoTo TrimFinalString:

        

RenewVariable:

        Temp = Left$(Temp, Len(Temp) - 2)

        VARENDOFLINE = InStr(VAR, Temp, Chr$(13))

        Temp = Left$(Temp, VAR) & PutVariable & "=" & PutValue & Mid$(Temp, VARENDOFLINE)

        GoTo TrimFinalString:

TrimFinalString:

        Temp = Mid$(Temp, 2)

        Do Until InStr(Temp, vbCrLf & vbCrLf & vbCrLf) = 0

        Temp = Replace(Temp, vbCrLf & vbCrLf & vbCrLf, vbCrLf & vbCrLf)

        Loop

    

        Do Until Right$(Temp, 1) > Chr$(13)

        Temp = Left$(Temp, Len(Temp) - 1)

        Loop

    

        Do Until Left$(Temp, 1) > Chr$(13)

        Temp = Mid$(Temp, 2)

        Loop

    

OutputAmendedINIFile:

        Open INIpath For Output As NF

        Print #NF, Temp

        Close NF

    

End Function

' Selesai

Nah sekarang kita tinggal compile exe aja caranya :

Masuk menu file > Make EXE file

Make EXE file

Sekedar info aja, nanti file *.ini bernama INFO.ini
