1. The document discusses creating a database in Microsoft Access 2007 and connecting it to a VB2010 project. It includes code for connecting to the database and performing basic CRUD operations like retrieving, adding, editing and deleting records. 2. Screenshots and code are provided for designing a form with textboxes, buttons, radiobuttons and a datagridview to display records. Code examples demonstrate querying the database and populating the form fields. 3. The form and buttons allow for inserting new records, editing existing ones based on a primary key, deleting records, and performing other basic data management tasks on a table called PEGAWAI within the Access database.

1. LATIHAN CRUD VB2010 DENGAN MS. ACCESS 2007 (BY: DIK-DIK.COM)
1. Buat database denganMs. Accces 2007, sbb:
Simpandi projectini,caranyaklikkananpada nama project:
Masuk ke FolderBin  Debug,masukandatabase ke folderini.
2. Buat Module Koneksi
KlikmenuProject  AddModule,ketikankodingberikutini:
Imports System.Data.OleDb
Module Module1
Public Conn As OleDbConnection
Public da As OleDbDataAdapter
Public ds As DataSet
Public cmd As OleDbCommand
Public rd As OleDbDataReader
Public Sub Koneksi()
Conn = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data
Source=PTABC.ACCDB")
Conn.Open()
End Sub
End Module

2. 3. Buat tampilan Design sbb:
Object Properti Value
Form Name Pegawai
Textbox1 Name txtKOPEG
Textbox2 Name txtNAPEG
Textbox3 Name txtUsia
Button1 Name btnNew
Text NEW
Button2 Name btnSave
Text SAVE
Button3 Name btnEdit
Text EDIT
Button4 Name btnDelete
Text DELETE
Button5 Name btnExit
Text EXIT
DataGridView Name DGV
Radiobutton1 Name OPTJK
RadioButton2 Name OPTJK2
Berikutkodingnyasbb:
