Hi,

What can I do to save a file to a certain location with the SaveFileDialog but the same file allready exists! I get an message to override it. And I click Yes. But then I get an error:
   
System.IO.IOExeption: the file c:\Users\Peter\Desktop\DBRoot.bak already exists.

        private void bbBackup_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
        {
            string pathDB = Application.StartupPath + "\\DBRoot.mdb";
            glucsTA.Update(glucsDS);
            glucsDS.AcceptChanges();
            suppTA.Update(suppDS);
            suppDS.AcceptChanges();
            favorTA.Update(favorDS);
            favorDS.AcceptChanges();
            calenTA.Update(calenDS);
            calenDS.AcceptChanges();
            SaveFileDialog saveFileDlg = new SaveFileDialog();
            saveFileDlg.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
            saveFileDlg.Filter = "Backup File (*.bak)|*.bak";
            saveFileDlg.FileName = "DBRoot.bak";
            try
            {
                if (saveFileDlg.ShowDialog() == DialogResult.OK)
                {
                    System.IO.File.Copy(pathDB, saveFileDlg.FileName);
                }
            }
            catch (Exception ex)
            {
                XtraMessageBox.Show(ex.ToString());
            }
        }

The role of the SaveFileDialog is to select a file. It flags the user if the file already exists, but does nothing else. It's you job to react.

It's your Copy that causes the problem. The way you call it, overwrite is not enabled.

Try passing true as a third parameter to Copy. This enables overwriting the file.
