Membuat Aplikasi pembelian dengan Visual FoxPro

     Untuk membuat program pembelian, hal ini adalah hal yang biasa dan sering banyak dibahas di banyak artikel. Tapi untuk kali ini, tetap membahas pembelian tapi dengan cara yang berbeda.

     Pengertian Pembelian :
     Pembelian dapat diartikan sebagai urutan kerja atau salah satu proses yang berkaitan dengan pengadaan barang dagangan.


 Persiapan untuk membuat program transaksi pembelian sbb :
1.  Buat project : PjPembelian

2.  Dabatase :dbPembelian

3.  Buat beberapa tabel, berikut struktur sbb:

Tabel Souvenir
kdbrg : Primary key

Isi record pada tabel souvenir sbb :

Tabel Supplier
kdsup : Primary key 

Tabel Pembelian
nofak : Primary Key
kdbrg : Foreign Key (Regular)

Tabel dtBeli
nofak : Foreign Key (Regular)
kdbrg : Foreign Key (Regular)

Design Form pembelian : 

     

Keterangan :
1,2,4,5, 11  : textbox
9                : Listbox
6,7,12        :  CommandButton

1  :  txtNoFak
2  :  txtTglFak
3  :  Combo1
4  :  txtNmSup
5  :  txtQty
6  :  CInput
7  :  cmdFirst, cmdBack, cmdNext, cmdLast
8  :  Text1
9  :  List1
10 : Grid1
11 : txtTotal, txtUbay, txtKembali
12 : cTambah, cSimpan, cKeluar

Untuk setiap textbox yang menampilkan angka, maka akan diubah tipe datanya menjadi numerik melalui builder

Untuk combobox

Klik kanan pada combo

Pilih Builder, lalu masukkan kdsup ke “selected field”

Untuk ListBox, sama seperti combo
KLik kanan pada List
Pilih Builder, lalu masukkan semua field ke "Selected Field"
