I made same thing in delphi long time ago and have fogotten how i was thinking that time. anyway i still have the code for it in delphi but im vey new in C# and would like someone to translate this delphi code to C# (VS 2005). Thanks guys.

procedure TForm1.ADOConnection1InfoMessage(Connection: TADOConnection;
  const Error: Error; var EventStatus: TEventStatus);


begin



  if error.Description = '10 percent backed up.' then Form1.Progressbar1.StepIt;
  if error.Description = '20 percent backed up.' then Form1.Progressbar1.StepIt;
  if error.Description = '30 percent backed up.' then Form1.Progressbar1.StepIt;
  if error.Description = '40 percent backed up.' then Form1.Progressbar1.StepIt;
  if error.Description = '50 percent backed up.' then Form1.Progressbar1.StepIt;
  if error.Description = '60 percent backed up.' then Form1.Progressbar1.StepIt;
  if error.Description = '70 percent backed up.' then Form1.Progressbar1.StepIt;
  if error.Description = '80 percent backed up.' then Form1.Progressbar1.StepIt;
  if error.Description = '90 percent backed up.' then Form1.Progressbar1.StepIt;
  if error.Description = '100 percent backed up.' then Form1.Progressbar1.StepIt;
end;

Add a handler to the InfoMessage event:

   SqlConnection conn = new SqlConnection();
   conn.InfoMessage += new SqlInfoMessageEventHandler(InfoMessageSink);

   private void InfoMessageSink(object source, SqlInfoMessageEventArgs e)
  {
  }

I am not sure I understand your question?  Stored procedure?  C# procedure?

Are you asking where to put that code?

What does it mean to be "Always On"?

Johan,

Try this:

private void InfoMessageSink(object source, SqlInfoMessageEventArgs e)
{
   memobox.Items.Add(e.Message);
}

I guess you mean that a Memo box is a multi-line TextBox control, right?

>>then no more
Are you getting an exception?  Is it completing, just not giving you the right progress?

forgot the code...

 

private void InfoMessageSink(object source, SqlInfoMessageEventArgs e)
  {
     // listBox1.Items.Add(e.Errors.Count);
             for (int i = 0; i < e.Errors.Count; i++)
    {       listBox1.Items.Add(e.Errors[i].Message);
             }
thanks for your help mate..
