Question

How can I save and retrieve an image from a SQL Server database in ASP, VB.NET ? When I double click on FileUpload1 control no Private Sub comes. What am I missing?

Answer 1

Create a table in a SQL Server 2000 database which has at least one field of type IMAGE.

CREATE TABLE [dbo].[tblImgData] (

    [ID] [int] NOT NULL ,

    [Name] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,

    [Picture] [image] NULL 

     ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

used a file open dialog box

this.openFileDialog1.ShowDialog(this);
string strFn=this.openFileDialog1.FileName;

using FileInfo class to retrieved the file size

FileInfo fiImage=new FileInfo(strFn);

Declare an array of that size

this.m_lImageFileLength=fiImage.Length;
m_barrImg=new byte[Convert.ToInt32(this.m_lImageFileLength)];

By using FileStream object, I filled the byte array

FileStream fs=new FileStream(strFn,FileMode.Open, 
              FileAccess.Read,FileShare.Read);
int iBytesRead=fs.Read(m_barrImg,0,
           Convert.ToInt32(this.m_lImageFileLength));
fs.Close();

see what you messing!
have fun!
