Membuat perintah insert,edit,hapus dan cari file image dengan VB.Net dan MS   Access

JUNE 28, 2012 1 COMMENT

Sudah lama gak pernah ngisi artikel di blog, karena terlalu sibuk dengan pekerjaan. Ok berhubung banyak yang

minta source code, gimana cara menginput file gambar sekaligus fungsi cari dan edit menggunakan VB.Net

dengan database MS Access, disini saya akan memulai langkah-langkah pembuatan projectnya. Pada postingan

sebelumnya sudah saya tulis juga artikel tentang perintah insert,edit dan hapus menggunakan VB.Net dan MS

Access dimana disana hanya disinggung mengenai modifikasi data dengan format string, sedangkan pada artikel

ini akan kita singgung gimana sih… sekalian input file gambar sekaligus. Langsung buka MS Access anda

kemudian buat sebuah database, disini saya beri nama BLOB lalu buah sebuah tabel dengan nama PEGAWAI.

susunlah field-fieldnya beserta tipe datanya seperti gambar dibawah ini.

Jika sudah selesai langsung buka MS Visual Studio anda, yang saya pake versi 9.0 atau lebih akrabnya VB.Net

2008, buat project dengan nama BLOB_project kemudian simpan. Desainlah form anda seperti gambar dibawah

ini

Jangan lupa buat sebuah modul yang berfungsi untuk menyimpan string koneksi ke database yang akan diakses

oleh form nantinya dan isinya seperti ini

Module modKoneksi

Public Koneksi As String = “Provider=Microsoft.Jet.OLEDB.4.0;Data Source=” & Application.StartupPath & “\

BLOB.mdb”

End Module

Berikut ini adalah isi dari source code yang ada pada form BLOB.

Imports System.IO

Imports System.Data.OleDb

Public Class frmBlob

Private path As String = “”

Private Sub btnBrowse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles

.FileName = “Pilih Gambar”

.Filter = “Type(*.jpg, *.jpeg, *.bmp, *.gif, *.png)|*.jpg; *.jpeg; *.bmp; *gif; *.png”

.ShowDialog()

path = .FileName

picPhoto.Image = Image.FromFile(path)

Sekilas mengenai isi source code dari program ini. Maaf jika kurang mengerti karena saya gak sempat

memaparkan fungsi dari masing-masing statement yang ada. Silahkan anda mempelajari sendiri biar ngerti he…
