Hi all, i'm using C# wpf ans MS Access database and my question is how to retrieve a picture from mdb file(saved as byte) to image control and the saving code works fine but the problem is on the retrieve.
////////////////////////////////////////////////////////saving code/////////////////////////////////////////////////////////////////////////////////
private void save_click(object sender, System.Windows.RoutedEventArgs e)
{
OleDbConnection con = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; DataSource=|DataDirectory|\\Location.mdb");
con.Open();
try
{
OleDbCommand cmd = new OleDbCommand("INSERT INTO vehicles (ID,manufacturer,model,doors,price_per_day,picture) VALUES (?,?,?,?,?,?)", con);
cmd.Parameters.AddWithValue("?", txtconstructeur.Text);
cmd.Parameters.AddWithValue("?", txtconstructeur.Text);
cmd.Parameters.AddWithValue("?", txtmodel.Text);
cmd.Parameters.AddWithValue("?", cmbdoors.Text);
cmd.Parameters.AddWithValue("?", txtprix.Text);
var bits = getJPGFromImageControl(img1.Source as BitmapImage);
cmd.Parameters.AddWithValue("?", bits);
cmd.ExecuteNonQuery();
con.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Erreur", MessageBoxButton.OK, MessageBoxImage.Error);
}
}
public byte[] getJPGFromImageControl(BitmapImage img1)
{
MemoryStream memStream = new MemoryStream();
JpegBitmapEncoder encoder = new JpegBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(img1));
encoder.Save(memStream);
return memStream.GetBuffer();
}
