For Save Images:
Private Sub Save()
Dim strConn, strQuery As String
Dim cmd As SqlCommand
Dim img As Image
Dim imagedata As Byte()
Dim imgFormat As Imaging.ImageFormat
Dim myParameter As SqlParameter
Try
img = Image.FromFile(Me.txtImage.Text)
imgFormat = img.RawFormat
imagedata = ConvertImageToByteArray(img, imgFormat)
strQuery = "Insert into TBL_STUDENT
(STUD_NAME,SUBJECT,NUMBER,IMAGES) values ('" & txtName.Text
& "','" & txtSubject.Text & "'," & txtNumber.Text & ",@Image)"
strConn = //Your Connection String
conn = New SqlConnection(strConn)
cmd = New SqlCommand(strQuery, conn)
myParameter = New SqlParameter("@Image",
SqlDbType.Image, imagedata.Length)
myParameter.Value = imagedata
cmd.Parameters.Add(myParameter)
conn.Open()
cmd.ExecuteNonQuery()
MsgBox("Saved Successfully", MsgBoxStyle.OkOnly)
Catch ex As Exception
End Try
End Sub
Private Shared Function ConvertImageToByteArray(ByVal
imageToConvert As System.Drawing.Image, ByVal formatOfImage
As Imaging.ImageFormat) As Byte()
Dim Ret As Byte()
Try
Using ms As New MemoryStream()
imageToConvert.Save(ms, formatOfImage)
Ret = ms.ToArray()
End Using
Catch generatedExceptionName As Exception
Throw
End Try
Return Ret
End Function
For Retrieve:
Private Sub RetrieveImages()
Dim strConn As String
Dim cmd As SqlCommand
Dim da As SqlDataAdapter
Try
strConn = //Connection string
conn = New SqlConnection(strConn)
cmd = New SqlCommand("Select * from
TBL_STUDENT", conn)
da = New SqlDataAdapter(cmd)
ds = New DataSet
da.Fill(ds)
Catch ex As Exception
End Try
End Sub
