Cara pembuatan client-server dengan menggunakan data karyawan

Server
Login

Form login

Perintah program nya
Private Sub Command1_Click()
If user.Text = "hery" And password.Text = "0902" Then
MDIForm1.Show
ElseIf user.Text = "" & password.Text = "" Then
MsgBox "Silahkan masukkan password login", vbCritical, "info"
user.SetFocus
Else
MsgBox "Password yang anda inputkan salah", vbCritical, "info"
user.Text = ""
password.Text = ""
End If
End Sub

Private Sub Command2_Click()
Unload Me
End Sub

Private Sub Form_Load()
user.Text = ""
password.Text = ""
password.PasswordChar = "*"
End Sub

Setelah anda buat login terus anda link kan ke MDI

Form MDI

Listing program nya
Private Sub e_Click()
Unload Me
End Sub

Private Sub ldm_Click()
Datakaryawan.Show
End Sub

Lalu anda memilih laporan data karyawan

Cara koneksi ke database
Pertama anda harus membuat data base nya terlebih dahulu dari
Start - all program - ms office - lalu pilih ms acces
Create a new file - blank database - lalu buat nama database nya
Create table in design view - isi field nya - save(ctrl+w)
Buat nama table nya lalu kembali ke table nya dan isi record nya
Selesai lah pembuatan table nya
Lalu anda koneksikan dari
Adodc klik kanan lalu pilih Adodc properties
Klik build pada menu general
Klik connection lalu pilih dari brows dan pilih database nya
Lalu pilih menu bar - record source
Ganti command type menjadi 2-adCmd table
Dan pilih table nya dari pilihan yang no :2(table or stored procedure name)
Lalu copy kan yang ada di menu general(use connection string)
            Dan pastekan di listing program modul(db.open”…”)

Adapun Langkah-langkah koneksi ke database adalah sebagai berikut:

Langkah 1

Langkah 2







Langkah 3









Langkah 4
