 | Subyek: .= CARA MEMBUAT ANTIVIRUS DENGAN MENGGUNAKAN VISUAL BASIC 6.0 =.  Thu Aug 11, 2011 7:31 pm | |
| Berikut cara membuat antivirus menggunakan visual basic .. Visual Basicnya download disini1.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 https://2img.net/r/ihimizer/img546/987/formawal.pngBeri nama form tersebut : frmUtama 2.Setelah form selesai di rubah namanya tambahkan component Mscomctl.Ocx dengan cara Klik Project -> Components -> Microsoft Windows Common Controls 6.0 -> lalu klik OK Contoh seperti gambar di bawah http://2.bp.blogspot.com/-9T4Guk54mGo/TVPhvB2SIXI/AAAAAAAAAIg/tDlgBZgQI4w/s1600/Component.bmp3.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 ^^ - Tambahkan Listview kedalam form dan beri nama lvScan http://4.bp.blogspot.com/-ph85_qpKBwM/TVPiJdI95sI/AAAAAAAAAIk/s7s9bUx_0OI/s1600/listview.bmpyang saya lingkari merah adalah listview yang telah di tambahkan ke dalam form. setelah itu setting listview dengan cara Klik Listview -> Disebelah kanan bawah ada kotak properties -> Custom lalu ikuti settingan seperti pada gambar di bawah ini http://2.bp.blogspot.com/-ImPNBY3VJ_Y/TVPidlnX-pI/AAAAAAAAAIo/CmKXztXnT64/s1600/gambar4.jpgLalu 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 Tambahkan picture box buat picture box itu sekecil mungkin dan beri nama sIcon 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 - 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 Tambahkan label dengan nama default Setting : Caption : Detected Tambahkan label dengan nama lblFileDet Setting : Caption : 0 Tambahkan label dengan nama default Setting : Caption : File Scanned Tambahkan label dengan nama lblFileScan Setting : Caption : 0 Tambahkan Textbox dengan nama txtFileScan Setting : Multiline : True Scroll Bar : 2-Vertical Tambahkan Command Button dengan nama cmdScan Setting : Caption : &Scan - 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 Tambahkan Command Button dengan nama cmdAction Setting : Caption : &Quarantine Tambahkan Command Button dengan nama cmdViewQ Setting : Caption : &View Quarantine File Tambahkan Command Button dengan nama cmdAction Setting : Caption : &Delete Tambahkan kode ini di dalamnya - 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 Tambahkan Command Button dengan nama cmdAction Setting : Caption : &Quarantine Tambahkan Command Button dengan nama cmdViewQ Setting : Caption : &View Quarantine File Lalu masukan code ini ke dalamnya - code:
Me.hide
frmquarantine.show
Code di atas berfungsi untuk memunculkan form quarantine dan meng enabled form utama nah selesai untuk memasukan control ke dalam formnya contoh form yang telah selesai. http://4.bp.blogspot.com/-AtUzd_myzQg/TVPlXQ1Z9iI/AAAAAAAAAIs/krTCH3So7xE/s1600/udah.bmplalu klik kanan pada form masukan kode di bawah ini - code:
Private Sub lvScan_ItemCheck(ByVal Item As MSComctlLib.ListItem)
UnSelect lvScan, "Di Karantina"
UnSelect lvScan, "Di Hapus"
End Sub
Private Function cmdEnable(hapus As Boolean, Quarantine As Boolean, openQuarantine As Boolean)
cmdAction(0).Enabled = hapus
cmdAction(1).Enabled = Quarantine
cmdViewQ.Enabled = openQuarantine
End Function
Private Function clear_log()
lblDirScan.Caption = 0
lblFileScan.Caption = 0
lblFileDet.Caption = 0
lvScan.ListItems.Clear
jumlahDir = 0
jumlahFile = 0
jumlahVirus = 0
End Function
lalu di Form_load() masukan kode ini - code:
On Error Resume Next
MkDir "Quarantine"

Code di atas adalah kumpulan fungsi etc untuk scanning,karantina,delete Ini adalah tampilan antivirus setelah di berikan module http://1.bp.blogspot.com/-CZCnZPdKa5c/TVPoeAnpf0I/AAAAAAAAAIw/tq53Q0vFOT0/s1600/module.bmpsekarang tinggal cara membuat form quarantinenya, caranya adalah sebagai berikut pada gambar berikut http://1.bp.blogspot.com/-r9zENldVom0/TVPpTSe4EPI/AAAAAAAAAI0/iOsKj9bOcik/s1600/form1.bmphttp://3.bp.blogspot.com/-f1QZAFe1Gbs/TVPpiIDxkQI/AAAAAAAAAI4/hBciG75K5DE/s1600/from2.bmphttp://2.bp.blogspot.com/-bpMw9NfGwKY/TVPpwnnZxXI/AAAAAAAAAI8/iuBbwNIg7bg/s1600/form3.bmpsetelah form baru sudah di buat,lalu rubah nama formnya menjadi frmQuarantine Tambah 1 buah listview dengan nama lvQ lalu setting listview tersebut sesuai dengan gambar di bawah ini,cara setting listview sudah tertera diatas. http://2.bp.blogspot.com/-ImPNBY3VJ_Y/TVPidlnX-pI/AAAAAAAAAIo/CmKXztXnT64/s1600/gambar4.jpgTambahkan 3 buah Command button dengan nama - cmdDelete - cmdRestore - cmdRestore(1) Tambahkan code di bawah ini ke dalam Command [ cmdDelete ] - code:
If lvQ.ListItems.Count = 0 Then Exit Sub
Dim Data() As String
If PathFileExists(Dat) <> 0 Then
Open Dat For Input As #1
Input #1, isi
Close #1
DeleteFile Dat
Else
isi = ""
End If
Data = Split(isi, "|")
For i = 1 To UBound(Data)
namafile = lvQ.SelectedItem.SubItems(2)
If namafile <> Split(Data(i), "?")(1) Then
nyu = nyu & "|" & Data(i)
End If
Next
DeleteFile AppPath & "Quarantine\" & lvQ.SelectedItem.SubItems(1)
Open Dat For Output As #2
Print #2, nyu
Close #2
MsgBox "Success Deleting File !!!", vbInformation, ""
UpdateQ
code di atas berfungsi untuk menghapus file yang telah di karantina Masukan code di bawah ini ke Command [ cmdRestore ] - code:
If lvQ.ListItems.Count = 0 Then Exit Sub
Select Case Index
Case 0
DecodeFile AppPath & "Quarantine\" & lvQ.SelectedItem.SubItems(1), lvQ.SelectedItem.SubItems(2)
MsgBox "File Restored to " & Chr(34) & lvQ.SelectedItem.SubItems(2) & Chr(34) & " !!!", vbInformation, ""
Case 1
sTitle = "Select path:" & vbNewLine & "Select path to restore file."
ThePath = BrowseFolder(sTitle, Me)
If ThePath <> "" Then
DecodeFile AppPath & "Quarantine\" & lvQ.SelectedItem.SubItems(1), ThePath & GetFileName(lvQ.SelectedItem.SubItems(2))
MsgBox "File Restored to " & Chr(34) & ThePath & GetFileName(lvQ.SelectedItem.SubItems(2)) & Chr(34) & " !!!", vbInformation, ""
End If
End Select
Fungsi code di atas berguna untuk me restore file kembali ke asalnya. lalu pada Form_Load() tambahkan code di bawah ini. - code:
frmUtama.Enabled = False
Dat = AppPath & "Quarantine\HN.dat"
UpdateQ
Masukan code di bawah ini ke dalam frmQuarantine yang telah anda buat tadi. - code:
Dim Dat As String
Private Sub UpdateQ()
lvQ.ListItems.Clear
Dim Data() As String
If PathFileExists(Dat) = 0 Then Exit Sub
Open Dat For Input As #1
Input #1, isi
Close #1
Data = Split(isi, "|")
For i = 1 To UBound(Data)
With lvQ.ListItems.Add(, , Split(Data(i), "?")(0))
.SubItems(1) = Split(Data(i), "?")(2)
.SubItems(2) = Split(Data(i), "?")(1)
End With
Next
Me.Caption = "Quarantine (" & lvQ.ListItems.Count & ")"
End Sub
Berfungsi untuk memanggil data yang ada di folder karantina. Hanya itu ilmu yang bisa saya bagikan. sekarang kita bukan hanya sebagai pemakai atau user sekrang kita sudah bisa mmembuat antivirus. dan ini adalah Screenshot antivirus yang kita buat tadi saat melakukan scanning. http://1.bp.blogspot.com/-n1g8W1CuZqU/TVPrmuBYH2I/AAAAAAAAAJA/WBeCU-C53yk/s1600/finish.bmp[center] SEKIAN ILMU DARI SAYA.. SEMOGA BERMANFAAT  | |
