CARA MEMBUAT ANTIVIRUS SENDIRI

CARA MEMBUAT ANTIVIRUS DNGAN VB

1.Buka program microsoft visual basic 6.0 -> Standard EXE -> OK maka akan tampil form baru sesuai dengan gambar di bawah,desain form sesuai keinginan anda

Beri nama form tersebut : frmUtama

(2)

contoh seperti gambar di bawah ini

3.Setelah component sukses di tambahkan langkah selanjutnya adalah menambah Command Button,Textbox,Listview,Picture Box

disini saya menggunakan desain yang sangat sederhana,desain bisa anda rubah sendiri sesuai kreatifitas anda ^^

(3)

yang saya lingkari merah adalah listview yang telah di tambahkan ke dalam form.

setelah itu setting listview dengan cara

(4)

Lalu pada tab Column Headers klik insert column - Column 1 beri nama : Virus Name

- Column 2 beri nama : Path

- Column 3 beri nama : Checksum Virus - Column 4 beri nama : Status Virus lalu klik Ok

(5)

Setting :

Appearance : Flat Auto Redraw : True Border Style : None Visible : False

Tambahkan Textbox ke dalam form dengan nama txtPath Setting :

Appearance : Flat Border Style : None

Tambahkan Command Button dengan nama cmdBrowse di samping Textbox yang telah di buat tadi Setting :

Caption : ...

Masukan Code ini ke dalam cmdBrowse

Spoiler: Code:

Dim Pathnya As String Pathnya = ""

Pathnya = BrowseFolder("Pilih folder yang akan di Scan:", Me) If Pathnya <> "" Then

txtPath.Text = Pathnya End If

Code di atas berfungsi untuk membuka kotak dialog yang berisi path" yang ada di dalam komputer lalu mencetaknya ke dalam textbox yang bernama txtPath

Tambahkan label dengan nama default Setting :

Caption : Dir Scanned

Tambahkan label dengan nama lblDirScan Setting :

Caption : 0

Caption : Detected

Tambahkan label dengan nama lblFileDet Setting :

Caption : 0

Caption : File Scanned

Tambahkan label dengan nama lblFileScan Setting :

Caption : 0

(6)

Multiline : True Scroll Bar : 2-Vertical

Tambahkan Command Button dengan nama cmdScan Setting :

Caption : &Scan

Spoiler: 'Code:

If cmdScan.Caption = "Scan" Then Pathnya = txtPath.Text

If Mid(Pathnya, 2, 1) <> ":" Or Pathnya = "" Then

MsgBox "Direktori Tidak Ditemukan", vbCritical, "Error" Exit Sub

Else

lvScan.Enabled = False cmdEnable False, False, False clear_log

cmdScan.Caption = "Stop" StopScan = False

FindFilesEx txtPath.Text, CBool(chkSubDir.Value)

MsgBox "Scan finished !" & vbNewLine & vbNewLine & "Total Dir Scanned = " & lblDirScan.Caption & _

vbNewLine & "Total File Scanned = " & lblFileScan.Caption & vbNewLine & "Total File Detected = " & lblFileDet.Caption, vbInformation, "Finish"

If lblFileDet.Caption <> "0" Then cmdEnable True, True, True Else

cmdEnable False, False, True End If

lvScan.Enabled = True cmdScan.Caption = "Scan" End If

Else

cmdScan.Caption = "Scan" StopScan = True

End If

fungsi kode di atas adalah untuk memulai scan pada antivirus

Tambahkan Command Button dengan nama cmdAction Setting :

Caption : &Delete

Caption : &Quarantine

Tambahkan Command Button dengan nama cmdViewQ Setting :

Caption : &View Quarantine File

(7)

Tambahkan kode ini di dalamnya

Spoiler: 'Code:

Dim DftrFile As String

DftrFile = GetSelected(lvScan) If DftrFile = "" Then

MsgBox "No Detected File(s) Selected", vbCritical, "" Exit Sub

End If

Select Case Index Case 0

clean = Action(DftrFile, lvScan, "D") MsgBox clean & " File(s) has been deleted" Case 1

clean = Action(DftrFile, lvScan, "Q")

MsgBox clean & " File(s) has been quarantine" End Select

Fungsi di atas adalah fungsi untuk menghapus/mengkarantina file yang terdeteksi

Caption : &Quarantine

Tambahkan Command Button dengan nama cmdViewQ Setting :

Caption : &View Quarantine File

Lalu masukan code ini ke dalamnya

Spoiler: Me.hide

frmquarantine.show

Code di atas berfungsi untuk memunculkan form quarantine dan meng enabled form utama

(8)

lalu klik kanan pada form masukan kode di bawah ini

Spoiler: /Code:

Private Sub lvScan_ItemCheck(ByVal Item As MSComctlLib.ListItem) UnSelect lvScan, "Di Karantina"

(9)

Private Function cmdEnable(hapus As Boolean, Quarantine As Boolean, openQuarantine As Boolean)

lagi sehingga muncul kontrol command1(2). Lakukan proses tersebut teru-menerus

sampai kontrol CommandButton berjumlah sepuluh buah.

3. Atur posisi kontrol-kontrol Command tersebut sehingga tampilan form menjadi

seperti berikut.

4. Kemudian atur properti caption untuk commandButton sehingga tampilannya

menjadi seperti berikut.

(42)

6. Atur properti kontrol TextBox dan CommandButton baru seperti berikut.

(43)

8. Buka jendela kode, lalu ketikkan kode berikut ini:

Private pilihan As String

Private x As Double

Private y As Double

Private Sub AC_Click()

Text1.Text = ""

y = x = 0

Tanda.Enabled = False

End Sub

Private Sub Akar_Click()

If x < 0 Then

Text1.Text = "Angka Tidak Boleh Negatif Coy"

Else

Text1.Text = Sqr(x)

End If

End Sub

Private Sub Bagi_Click()

Text1.Text = ""

(44)

y = x

x = 0

Tanda.Enabled = False

End Sub

Private Sub Command1_Click(Index As Integer)

Text1.Text = Text1.Text & Command1(Index).Caption

x = Text1.Text

Tanda.Enabled = True

End Sub

Private Sub Form_Load()

Tanda.Enabled = False

End Sub

Private Sub Hasil_Click()

If pilihan = "tambah" Then

x = y + x

Text1.Text = x

ElseIf pilihan = "kurang" Then

x = y - x

Text1.Text = x

ElseIf pilihan = "kali" Then

x = y * x

Text1.Text = x

ElseIf pilihan = "bagi" And x <> 0 Then

x = y / x

Text1.Text = x

Else

Text1.Text = "Tidak Terdefinisi"

End If

(45)

Private Sub Kali_Click()

Text1.Text = ""

pilihan = "kali"

y = x

x = 0

Tanda.Enabled = False

End Sub

Private Sub Koma_Click()

If Text1.Text = "" Then

Text1.Text = "0."

Else

Text1.Text = Text1.Text & "."

End If

End Sub

Private Sub Kuadrat_Click()

Text1.Text = x ^ 2

End Sub

Private Sub Kurang_Click()

Text1.Text = ""

pilihan = "kurang"

y = x

x = 0

Tanda.Enabled = False

End Sub

Private Sub Tambah_Click()

Text1.Text = ""

pilihan = "tambah"

y = x

(46)

Tanda.Enabled = False

End Sub

MEMBUATPROGRAM PORT PARALEL LED BERJALAN DENGAN VB

1. Buatlah hardwarenya dengan 12 buah led dimana 8 led pertama sambungkan dengan pin data

(2-9) dan 4 led trakhir sambungkan dengan pin control (1,14,16,17) jangan lupa tambahkan

resistor dan penyambungan system katoda.

2. Buat project baru kemudian tambahkan 12 shape untuk simulasi lednya, 1 label untuk judul

kemudian 5 commandbutton dan 4 buah timer.

3. Kemudian desain lah menjadi seperti gambar berikut :

4. Atur properties masing-masing komponen seperti untuk shape backstyle ubah menjadi

1-opaque kemudian backcolornya pilih warna putih kemudian unutk timer semua interval beri

nilai 100 dan dalam keadaan false.

5. Save project dan Form di folder yang sama lalu copykan inpout32.dll pada folder tempat

penyimpanan tersebut.
