Setelah sekian lama vakum dari dunia blog karena banyaknya
aktifitas yang saya lakukan (padahal
cuma main game online) akhirnya bisa update artikel lagi di awal tahun 2013 ini
(bulan 3 masih awal kan?) :D .., okay sambil merapikan blog yang mulai usang karna
lama gak di urus, pada kesempatan kali ini saya akan berbagi tutor tentang cara
koneksi database MySQL dengan Visual Basic 6.0. Sebelum kita mulai, pertama
kalian harus install dulu driver MySQL ODBC untuk menghubungkan database
kedalam program nantinya. Kalau belum punya drivernya silahkan download dulu
filenya di sini.
Nah jika drivernya sudah terinstall sekarang kita mulai
tutornya, pertama buat dulu database MySQLnya dengan Xampp di PHPMyadmin dengan
nama latihansqldb.
Nama table = latihansqldb
Nama
|
Tipe
Data
|
Keterangan
|
Nrp
|
Varchar(10)
|
Primary Key
|
Nama
|
Varchar(30)
|
|
jurusan
|
ENUM(‘Sistem Informasi’,’Teknik Informatika’,’Komputer
Akuntansi’,’Manajemen Informatika’)
|
Default : Sistem Informasi
|
Atau anda bisa langsung import table databasenya dari folder
File Database yang sudah saya sediakan di file source code nya.
Setelah membuat database selesai, desain form seperti
dibawah ini :
Komponen yang digunakan dalam form ini dan konfigurasinya
adalah :

Text2

Txtnama
|
Text3
|

|

|

|

|
Gridmhs

Jika sudah selesai desain formnya,, sekarang kita buat modul
untuk setting koneksi ke database MySQL yg telah kita buat sebelumnya, untuk
membuka modul caranya pilih menu Project > Add Modul > Open. Setelah
muncul jendela koding modul, ketikkan koding dibawah ini :
========================================================================
Option Explicit
Public KonekDb As New ADODB.Connection
Public Rs_mhs As New ADODB.Recordset
Public SQLubah, SQLsimpan, SQLhapus As String
Sub BukaDatabase()
Dim strSS,
strPort, strDB, strUID, strPWD As String
strSS =
"localhost"
strPort =
"3306"
strDB =
"latihansqldb"
strUID =
"root"
strPWD =
""
Set KonekDb = New ADODB.Connection
KonekDb.CursorLocation = adUseClient
KonekDb.ConnectionString = "" _
&
"DRIVER={MYSQL ODBC 3.51 Driver};" _
&
"SERVER=" & strSS & ";" _
&
"DATABASE=" & strDB & ";" _
&
"UID=" & strUID & ";" _
&
"PWD=" & strPWD & ";" _
&
"OPTION="
On Error Resume
Next
If KonekDb.State =
adStateOpen Then
KonekDb.Close
Set KonekDb =
New ADODB.Connection
KonekDb.Open
Else
KonekDb.Open
End If
If Err.Number
<> 0 Then
MsgBox
"GAGAL KONEKSI SERVER", vbOKOnly, "Kesalahan"
End If
End Sub
========================================================================
Setelah membuat modul koneksi, sekarang masuk kedalam form
yang kita buat tadi dan ketikkan koding berikut di form load, tombol simpan,
edit, hapus, keluar dan flexgrid.

Jika semua koding sudah
diketikkan coba jalankan form yang telah diisi dengan koding diatas, jika
berhasil, maka akan tampil seperti gambar dibawah ini :
Okay, sampai disini dulu tutor vb
nya, semoga bermanfaat buat teman2 yang ingin belajar VB 6.0. ^^
Sampai jumpa lagi di pembahasan
selanjutnya :D
