Pertemuan Pertama

Materi : Membuat Aplikasi Database Billing Management Sistem

Sub Materi : Membuat Database di Microsoft SQL Server 2005

: Membuat Projek Baru di Microsoft Visual Studio 2005

: Membuat Dataset di Microsoft Visual Studio 2005

: Membuat Form Deposit

Membuat Database di Microsoft SQL Server 2005

Langkah Pembuatan:

1. Buka aplikasi MS SQL Server 2005

2. Buat sebuah database baru dengan nama “Billing”

3. Susun dan buat tabel-tabel database sesuai gambar berikut:

4. Buat tabel dengan nama “Deposit” dengan field seperti berikut:

5. Buat tabel dengan nama “Member” dengan field seperti berikut:

1


6. Buat tabel dengan nama “Setting” dengan field seperti berikut:

7. Buat tabel dengan nama “Transaction” dengan field seperti berikut:

Membuat Projek Baru di Microsoft Visual Studio 2005

Langkah Pembuatan:

1. Buka aplikasi Microsoft Visual Studio 2005

2. Buat sebuah project baru -> Pilih menu “New Project”

2


3. Beri nama “Billing” untuk projek baru ini

4. Ada beberapa jendela kerja di Microsoft Visual Studio, diantaranya:

a) Jendela “Toolbox”

Kotak dialog ToolBox ini berisi semua komponen yang akan dipakai untuk membuat sebuah project

aplikasi. ToolBox terbagi menjadi beberapa sub bagian untuk mempermudah pemakai

menggunakannya diantaranya :

3


Common Controls

Containers

Menus and Toolbar

Data

Component

Printing

Dialog

Cristal Report (Tambahan jika sudah menginstal Cristal Report)

b) Jendela “Solutions Explorer”

Kotak dialog ini digunakan untuk mengelola (menambah, menghapus, mengganti Item) project yang

dibuat. Di kotak ini kita bisa menambahkan sebuah Form Baru maupun Item Baru yang akan

disisipkan kedalam project yang dibuat. Dalam Kotak ini terdapat 2 Tab Control yaitu Solution

Explorer dan Data Sources.

Data Sources digunakan untuk mengelola DataSet yang sudah kita buat. DataSet sendiri terdiri dari

konfigurasi Tabel Tabel Database.

c) Jendela “Property”

4


Kotak dialog ini digunakan untuk memberikan pengaturan pada objek yang ada di Form Project.

d) Jendela “Event”

Kotak dialog Event ini digunakan untuk memberikan perintah pada objek sesuai dengan kejadian

yang diingginkan.

Membuat Dataset di Microsoft Visual Studio 2005

Langkah Pembuatan:

1. Buat sebuah data source baru -> pilih icon “Add New Data Sourses” di tab Data Sources

5


2. Pihih “Database” pada pilihan Tipe Data Sources

3. Buat koneksi baru dengan cara Pilih “New Connection”

4. Pilih Data Source “Microsoft SQL Server” dan pilih Data Provider “.Net For SQL Server”

6


5. Pilih server Name sesuai dengan nama komputer yang dipakai untuk server database ->

NamaKomputer\SQLEXPRESS

6. Isikan pilihan database name “Billing”

7. Klik “Test Connection” untuk mengetahui apakah koneksinya sukses atau gagal

8. Klik “Ok"

Membuat Deposit Form di Microsoft Visual Studio 2005

Langkah Pembuatan:

Public Property Deposit_Id() As String Get Return varDepositId End Get Set(ByVal value As String) varDepositId = value End Set End Property

3. Buat Query Adapter di Dataset pada tabel “Deposit” dengan nama “FillByMonthLastTrxId “ yang

berfungsi sebagai filter untuk membuat kode “Id Deposit” secara otomatis, querynya seperti

berikut:

SELECT Deposit_Id, Member_Id, Name, Date, Price, Status

FROM Deposit

WHERE (SUBSTRING(Deposit_Id, 5, 2) = @Year) AND

(SUBSTRING(Deposit_Id, 7, 2) = @Month)

tmp_Dep_Id = "" Year = Microsoft.VisualBasic.Right(Me.DateDateTimePicker.Value.Year.ToString, 2) Month = Me.DateDateTimePicker.Value.Month.ToString.PadLeft(2, "0")

Me.DepositTableAdapter.FillByMonthLastTrxId(Me.BillingDataSet.Deposit, Year, Month) If Me.BillingDataSet.Deposit.Rows.Count > 0 Then tmp_Dep_Id = "DEP-" & Microsoft.VisualBasic.Right(Me.DateDateTimePicker.Value.Year.ToString, 2) & Me.DateDateTimePicker.Value.Month.ToString.PadLeft(2, "0") LastTrxId = CInt(Microsoft.VisualBasic.Right(Me.BillingDataSet.Deposit.Item(0).Deposit_Id, 4)) + 1 tmp_Dep_Id = tmp_Dep_Id & "-" & LastTrxId.ToString.PadLeft(5, "0") Me.Deposit_IdTextBox.Text = tmp_Dep_Id Else tmp_Dep_Id = "DEP-" & Microsoft.VisualBasic.Right(Me.DateDateTimePicker.Value.Year.ToString, 2) & Me.DateDateTimePicker.Value.Month.ToString.PadLeft(2, "0") & "-" & "00001" Me.Deposit_IdTextBox.Text = tmp_Dep_Id End IfEnd Sub

INSERT INTO [Deposit] ([Deposit_Id], [Member_Id], [Name], [Date],

[Price], [Status]) VALUES (@Deposit_Id, @Member_Id, @Name, @Date,

@Price, @Status)

6. Buat event “Click” pada tombol “Save Data”. Fungsinya untuk menyimpan data ke database,

kodenya seperti berikut:

8


Me.DepositTableAdapter.InsertQuery(Me.Deposit_IdTextBox.Text, Me.Member_IdTextBox.Text, Me.NameTextBox.Text, Me.DateDateTimePicker.Value, Me.PriceTextBox.Text, "COMPLETE") MsgBox("Transaksi disimpan") Me.DepositBindingNavigatorSaveItem.Enabled = FalseEnd Sub

7. Buat kode di event “Load” seperti berikut:

Private Sub DepositForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'TODO: This line of code loads data into the 'BillingDataSet.Deposit' table. You can move, or remove it, as needed. 'Me.DepositTableAdapter.Fill(Me.BillingDataSet.Deposit) If Me.varDepositId = "" Then Me.Member_IdTextBox.Text = "" Me.NameTextBox.Text = "" Me.StatusTextBox.Text = "COMPLETE" 'Me.User_IdTextBox.Text = CurrentUser.User_Id Me.PriceTextBox.Text = "" GetTrxId()

End If

End Sub

8. Yang terakhir berikan event perintah “Click” di tombol cari anggota, seperti berikut:

Private Sub SearchMemberButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SearchMemberButton.Click My.Forms.MemberListForm.ShowDialog() If My.Forms.MemberListForm.MemberId <> "" Then Me.Member_IdTextBox.Text = My.Forms.MemberListForm.MemberId Me.NameTextBox.Text = My.Forms.MemberListForm.MemberName End If End Sub
