SUB PROGRAMPROCEDURE (SUB) dan FUNCTION
PROCEDURE / SUB• Adalah sekumpulan statemen dari visual basic yang
diberi nama, tidak menghasilkan nilai balik, hanyamengerjakan sejumlah proses
Private /public sub nmsub(byref/byval/optional/paramarray namapara as type )PerintahPeriintah

Nmsubnama subprogram / procedureByref melewatkan parameter secara referensiByvalmelewatkan parameter secara nilaiOptional nilai parameter boleh tidak diisiParamarrayparameter berupa arrayNamaparanama parameter
Catatan :•Parameter bisa lebih dari 1•Parameter optional harus diletakan diurutan belakang
Memanggil Procedure / Sub•Namaprocedure(para,para,para…)•Call Namaprocedure(para,para,para…)

Catatan :•Parameter bisa lebih dari 1•Parameter optional harus diletakan diurutan belakang
Memanggil function•Var=Namafunction(para,para,para…)
Private Function Sum(ParamArray args() As Variant) As SingleDim total As SingleDim i As Integer
For i = 0 To UBound(args)total = total + args(i)
Next i
Sum = total
End Function
Pada button 1 dapat disii denganprint Sum(1,2,3,4,5)AtauPrint Sum(11, 14, 55, 78, 102, 45, 99, 101, 55, 21)
Contoh function dengan parameter array
Private Function Sum(ParamArray args() As Variant) As SingleDim total As SingleDim i As Integer
For i = 0 To UBound(args)total = total + args(i)
Next i

Function dengan return valueberupa array
Private Function fstat(ByVal ParamArray args() As Object) As Single()Dim hasil(3) As SingleDim i As IntegerFor i =0 To UBound(args)
hasil(0) = hasil(0) + args(i)If i = 0 Then

Next iReturn hasil
End Function
pada button1 click ketik program berikutDim statistik As Single() = fstat(1, 6, 2, 7, 3, 9, 4, 10, 8, 5)TextBox1.Text = statistik(0)TextBox2.Text = statistik(1)TextBox3.Text = statistik(2)

Overloading Function
• Beberapa function mempunyai nama samatetapi mempunyai parameter berbeda
Function hitung(ByVal bil1 As Integer, ByVal bil2 As Integer) As Integerhitung = bil1 + bil2
End Function
Function hitung(ByVal bil1 As Integer, ByVal bil2 As Integer, ByVal bil3 As Integer) As Integerhitung = bil1 + bil2 + bil3
End Function
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.ClickTextBox1.Text = hitung(1, 2, 3)
End Sub
