Question How to put OLEObject image from Access into PictureBox control

[DaveRI]

Hello All,

I'm trying to pull an image stored as an OLEObject from an Access DB and load it into a PictureBox control using VB.NET. Based on where the exception is getting thrown, the code is making a connection to the database and the query is working. However, I am getting a System.ArgumentException message that tells me the "Parameter is not valid" on the following line:

newImage = Image.FromStream(imgMemoryStream)

Full Code:

Imports System.IO
Imports System.Data.OleDb


Public Class Form1


Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim imgByte() As Byte
Dim connString As String
Dim sqlCommand As String
Dim comm As OleDbCommand
Dim WorkingDirectory As String = Application.StartupPath
Dim newImage As Image
connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + "Photo.accdb; Persist Security Info=True"
Dim cnction As New OleDbConnection(connString)
cnction.Open()
sqlCommand = "SELECT imgData FROM Photo WHERE ID=1"
comm = New OleDbCommand(sqlCommand, cnction)
imgByte = comm.ExecuteScalar()
Dim imgMemoryStream As MemoryStream = New MemoryStream(imgByte)
newImage = Image.FromStream(imgMemoryStream)
PictureBox1.Image = newImage




End Sub

How are you saving the image in the first place? Is it done through your app using similar code? If not, try doing so and see if it works.

Thanks for the reply. I saved the .jpg image using access. I'll try to create the save the image through VB and see if that makes any difference.
