SQL

Hi,
From my asp.net form, I am trying to save a picture to my SQL Database.  Problem is the File Upload button just takes the name of the file, not the full path.  When I try to save it, it says file not found.
Is there something like OpenFileDialog in webforms, as I use that for vb.net and that works excellent.

Thanks

That's because the FileUpload control does not save the file to disk - it doesn't know what you want to do with it.
Here is the code I use:

C#

/// <summary>
/// Save an upload into the database.
/// </summary>
/// <param name="fl">Control containing the download.</param>
/// <returns>Status as a string</returns>
private string SaveUpload(FileUpload fl)
    {
    if (fl.HasFile)
        {
        try
            {
            int version = 0;
            string filename = Path.GetFileName(fl.FileName);
            byte[] filedata = fl.FileBytes;
            string strCon = ConnectionStrings.Download;
            using (SqlConnection con = new SqlConnection(strCon))
                {
                con.Open();
                // Stick file into database.
                using (SqlCommand ins = new SqlCommand("INSERT INTO dlContent (iD, fileName, description, dataContent, version, uploadedOn) " +
                                                       "VALUES (@ID, @FN, @DS, @DT, @VS, @UD)", con))
                    {
                    ins.Parameters.AddWithValue("@ID", Guid.NewGuid());
                    ins.Parameters.AddWithValue("@FN", filename);
                    ins.Parameters.AddWithValue("@DS", "");
                    ins.Parameters.AddWithValue("@DT", filedata);
                    ins.Parameters.AddWithValue("@VS", version);
                    ins.Parameters.AddWithValue("@UD", DateTime.Now);
                    ins.ExecuteNonQuery();
                    }
                }
            return string.Format("{0} uploaded, version = {1}", filename, version);
            }
        catch (Exception ex)
            {
            return "The file could not be uploaded. The following error occured: " + ex.Message;
            }
        }
    return "Please select a file.";
    }

That gets called from the Upload Button Click event handler.
