Let me rephrase my question.

I'm using vb.net. I'm doing the following and this exeption was thrown. ex.message = invalid parameter used.

The msaccess db table column is set to type ole object. Try this, go to the db table and right click on the column and click inser object and insert a bmp. The column value will now display bitmap image. Try your code against that and you'll experience the problem. Why?

Dim cmd As OleDbCommand = New OleDbCommand(sql, cnn)
cnn.Open()
Dim b() As Byte
b = cmd.ExecuteScalar()
cnn.Close()


If (b.Length > 0) Then
Dim stream As New MemoryStream(b, True)
stream.Write(b, 0, b.Length)
'Display image
Dim PictureBox1 As New System.Windows.Forms.PictureBox

'exception is thrown at this statement
PictureBox1.Image = New Bitmap(stream)
'ex.message = invalid parameter used.

stream.Close()
End If
'conn.Close()


Why?

Thanks,
Glenn
