--> Hanya Angka yang bisa di Input dalam TextBoxt

Private Sub txtNomor_KeyPress(KeyAscii As Integer)
If Not (KeyAscii >= Asc("0") & Chr(13) _
And KeyAscii <= Asc("9") & Chr(13) _ Or KeyAscii = vbKeyBack _ Or KeyAscii = vbKeyDelete _ Or KeyAscii = vbKeySpace) Then Beep KeyAscii = 0 End If End Sub

--> Hanya Huruf

Private Sub txtNama_KeyPress(KeyAscii As Integer)
If Not (KeyAscii >= Asc("a") & Chr(13) _
And KeyAscii <= Asc("z") & Chr(13) _ Or (KeyAscii >= Asc("A") & Chr(13) _
And KeyAscii <= Asc("Z") & Chr(13) _ Or KeyAscii = vbKeyBack _ Or KeyAscii = vbKeyDelete _ Or KeyAscii = vbKeySpace)) Then Beep KeyAscii = 0 End If End Sub

--> membersihkan Seluruh Control TextBox dan Combo Box

Sub Clear()
For Each Control In Me.Controls
If TypeOf Control Is TextBox Then
Control.Text = ""
End If
If TypeOf Control Is ComboBox Then
Control.Text = ""
End If
Next Control
End Sub

NB: jika ada tombol yang lain tinggal di tambah kondisi IFnya aja, dan tuk menonaktifkan seluruh tombol tinggal ganti "Control.Text=Enabled" aja

--> Get Auto Number

Private Sub Auto()
Dim Urutan As String * 10
Dim Tgl As String
Dim Hitung
Set TMasuk = New ADODB.Recordset
TMasuk.Open "Select * from Masuk", Persediaan, adOpenDynamic, adLockPessimistic
'TMasuk.MoveFirst
Tgl = Format(Now, "yy/mm/dd")
With TMasuk
If .RecordCount = 0 Then
Urutan = Right(Tgl, 2) + Mid(Tgl, 4, 2) + Left(Tgl, 2) + "0001"
Else
.MoveLast
If Left(![No Masuk], 6) <> Right(Tgl, 2) + Mid(Tgl, 4, 2) + Left(Tgl, 2) Then
Urutan = Right(Tgl, 2) + Mid(Tgl, 4, 2) + Left(Tgl, 2) + "0001"
Else
Hitung = (![No Masuk]) + 1
Urutan = (Right(Tgl, 2) + Mid(Tgl, 4, 2) + Left(Tgl, 2)) + Right("0000" & Hitung, 4)
End If
End If
txtNomor = Urutan
End With
End Sub

--> Mengambil record ke dalam COmboBox

Sub DaftarPelanggan()
Me.MousePointer = 11
Pesan = "Select * from Pelanggan Order By kodePlg"
Set TPelanggan = New ADODB.Recordset

cmbPlg.Clear

TPelanggan.MoveFirst
While Not TPelanggan.EOF
cmbPlg.AddItem TPelanggan!KodePlg
TPelanggan.MoveNext
Wend
End If
TPelanggan.Close
Set TPelanggan = Nothing
Me.MousePointer = 1
End Sub
