Hi!

I'm debugging a windows service and it works perfect but there is one thing
that I wonder about and that is what happen
to all those calls to the t_Elapsed method when I keep Visual Studio
executing on the same row without stepping through the t_Elapsed method
code.
I mean the service control manager will keep calling the t_Elapsed method
every 10 seconds.
When I test this nothing unusual happen accept that when I step through the
t_Elapsed method another call is pending
to the t_Elapsed method. So there will be many pending calles buffered to
the t_Elapsed method if I keep
Visual Studio on the same row without stepping through the code.

So my question is if anyone know how the implementatin is used with the
buffering of calls to the t_Elapsed method?
For example is there some kind of limit of how many pending calls there
could exist to the t_Elapsed method.
As I mention when I test this I didn't discoved any kind of error so there
might be some kind of ringbuffer overwriting old pending calls with new
pending calls.


void t_Elapsed(object sender, ElapsedEventArgs e)
{
try
{
// Send the HTTP request
string url = "http://www.microsoft.com";
HttpWebRequest g = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse r = (HttpWebResponse)g.GetResponse();

// Log the response to a text file
string path =
AppDomain.CurrentDomain.SetupInformation.ApplicationBase + "log.txt";
TextWriter tw = new StreamWriter(path, true);
tw.WriteLine(DateTime.Now.ToString() + " for " + url + ": "
+ r.StatusCode.ToString());
tw.Close();

// Close the HTTP response
r.Close();
}
catch (Exception ex)
{
System.Diagnostics.EventLog.WriteEntry("Application",
"Exception: " + ex.Message.ToString());
}

//Tony
