Memunculkan Field Gambar

Sedikiit berbagi.. Mungkin Teman2 ada yang kesulitan mengenai memunculkan file Image Database Acces ke VB. Saya menggunakan dua Cara untuk mewujudkan hal tersebut diantaranya adalah :

1. Me-Load Gambar dalam Kontrol Image dari String Alamat Gambar yang telah ada di Field Database, jadi Field dalam tabel bertype Text. Keuntungannya Database berukuran lebih Kecil dibanding cara kedua.
2. Meload Gambar Dari Field yang bertype OLE Object kedalam kontrol Image. Keuntungannya semua gambar dalam satu database sehingga dapat sebagai pustaka gambar.




Kali ini kita akan menggunakan cara yang kedua, Buat Database Acces bernama "terserahData.mdb" terdiri atas satu Tabel yaitu "TblPhotoSaja" dan di dalamnya buat field Type Ole Object beri nama "Image",serta satu field lagi Bertype AutoNumber berinama "Id", Langsung saja ^_^ ini saourcenya..
