I\'m saving a picture in an access database, and everything is OK but when I want to retrieve it I can\'t.

This is my code to save the picture in database. I need code t

Answer 1

But I don't think that you're saving the Image in a Binary format, and even you have not put your last update on this query. So I assume you have saved the Image in a Binary form.
Let's take a look.

I assume that if you've saved the Image in "Long Binary data", then you have to call that Image by using the Image ID. Or, better, if you're using a Student's Number.
Now what you do here is simply make a TextBox (i.e. Textbox1). Then follow the code.

Open a Connection first then:

Try
    Dim command As New OleDbCommand("SELECT Image FROM Table WHERE Rollno ='" & textbox1.Text & "'", myconnection)
    command.Parameters.AddWithValue("@Rollno", Textbox1.Text)
    Dim pictureData As Byte() = DirectCast(command.ExecuteScalar(), Byte())

    myconnection.Close()
    command.Dispose()
    Dim stream As New IO.MemoryStream(pictureData)
    Me.PictureBox1.Image = Image.FromStream(stream)'See in this picturebox1 you're showing the Image.
    '' NOTE: don't dispose the stream!!
Catch ex As Exception
    Label3.ForeColor = Color.Red
    Label3.Text = "The Given Rollno has not found in the database"
    Return
End Try
