6. MODIFIKASI
a) Saat form dijalankan : semua isian tidak
aktif, tombol isidata dan tutup aktif, tombol clear tidak aktif
b) Saat ditekan tombol isi data : kodebarang,
jumlahbarang, cara beli, tombol clear, aktif, tombol isidata tidak aktif
c) Saat ditekan combol clear sama dengan saat form
dijalankan
7 7. Buat tampilan sebelumnya menjadi seperti

-
Hapus Label bayar,
serta script atau kodingnya
-
Hapus textbox uang
bayar & txtkembalian, serta script atau kodingnya
-
Hapus button kembalian,
serta script atau kodingnya
-
Tambahkan button Isi data
-
Tambahkan GroupBox1
8. Pindahkan Semua isian, kecuali semua label ,
button isi data dan button tutup
9. Tambahkan GroupBox1.Enabled = False pada form1,
sehingga kodingnya seperti berikut
cmbcode.Items.Add("SPT")
cmbcode.Items.Add("SND")
cmbcode.Items.Add("TST")
cmbcode.Items.Add("TOP")
cmbcode.Items.Add("TAS")
GroupBox1.Enabled = False
10. Pada button isi data,
isikan kodingnya seperti berikut
cmbcode.Items.Add("SPT")
cmbcode.Items.Add("SND")
cmbcode.Items.Add("TST")
cmbcode.Items.Add("TOP")
cmbcode.Items.Add("TAS")
GroupBox1.Enabled = False
11. Pada button Clear, tambahkan
koding ”yang bercetak tebal”, sehingga seperti berikut
txtbayar.Clear()
txtdiskon.Clear()
txtharga.Clear()
txtjumlah.Clear()
txtnama.Clear()
txttotal.Clear()
Me.radiotunai.Checked
= False
Me.radiokredit.Checked
= False
cmbcode.Text = ""
GroupBox1.Enabled = False
Button1.Enabled = True
12. Sekarang Test Program yang telah kita
buat.
a. Saat form dijalankan : semua isian tidak
aktif, tombol isidata dan tutup aktif, tombol clear tidak aktif
b. Saat ditekan tombol isi data : kodebarang,
jumlahbarang, cara beli, tombol clear, aktif, tombol isidata tidak aktif
c. Saat ditekan tombol clear sama dengan saat
