[ranjana1980]

In my project of desktop application using c#.net save image in database during registration of student But it is not mandatory.Without Browse the image i click on insert button it gives error "Empty path name is not legal".

con.ConnectionString = "Data Source=XPO3;Initial Catalog=Imsapplication;Integrated Security=True";
           con.Open();
           //Cryclass cc = new Cryclass();
           string filepath = textBox2.Text;
           FileStream fs = new FileStream(filepath, FileMode.Open, FileAccess.Read);
           BinaryReader br = new BinaryReader(fs);
           byte[] photo = br.ReadBytes((int)fs.Length);
 
 
           br.Close();
           fs.Close();

hi ranjana,
i got the code in VB.net 2003 , it is working fine .

imgstyle is Picture Box

Dim msImage As New MemoryStream
dim strSQL as string

imgStyle.Image.Save(msImage, imgStyle.Image.RawFormat)

Dim arrImage() As Byte = msImage.GetBuffer
dim cmd as sqlcommand

msImage.Close()
strSQL = "INSERT INTO tblDesignDetails (imgDesign) VALUES ( @Picture )"

cmd = New SqlCommand(strSQL, Cn)
cmd.Parameters.Add(New SqlParameter("@Picture", SqlDbType.Image)).Value = arrImage
