Posted on June 1, 2011. Filed under: IT, VB.NET | Tags: Excel, FireBird, Microsoft Office, MS SQL Server, MySQL, Office Automation, Open Office, Oracle, Sybase, Visual Basic NET |

Tulisan dibawah ini akan membahas bagaimana proses “Excel Office Automation ” pada Visual Basic.NET (EOA VB.NET),namun sebelum anda membuat sebuah proses EOA VB.NET,sebaiknya anda sudah familiar dengan Visual Basic.NET (Form,Class,Event,Property,Reference dll) karena dalam tutorial ini saya tidak mencantumkan tutorial bagaimana membuat beberapa hal tersebut.
Tutorial EOA VB.NET berikut ini akan menuntun kita bagaimana data yang ada kemudian diexport kedalam sebuah file berformat excel. Karena dalam banyak hal ternyata laporan-laporan dari end user adalah berformat excel. EOA VB.NET akan membuat pekerjaan user lebih efisien, karena laporan yang ada sudah terotomatisasi sehingga user tidak perlu lagi menghabiskan waktu untuk tampilan file excel tersebut.
Sebelum anda membuat EOA VB.NET,maka anda membutuhkan beberapa file yang diperlukan pada proses ini, diantaranya adalah :
– Interop.excel.dll
– Microsoft.Office.Core.dll
– Microsoft.Office.Interop.Excel.dll

Ketiga file ini harus berada didalam folder references dari solution yang akan anda buat
Gambar dibawah ini adalah sebuah data contoh yang akan diexport menjadi sebuah file berformat excel
