Net Framework2.0, Download:xml file using a stored configuration information, which need to access the web site storage, the sample structure is as follows: an item on behalf of a visit, url is a specific site, set to automatically update the url website address, you can update with a query string to set the amount, time access time that day, time can only be accurate to 1 minute and must ensure that every item in the same minute, only a url tasks. program uses a timer, every 20 seconds to scan the configuration item in the need to access the site, if there is one visit the site. Relevant code is as follows: public Job () { System.Timers.Timer myTimer = new System.Timers.Timer (20000); myTimer.Elapsed + = new ElapsedEventHandler (myTimer_Elapsed); myTimer.Enabled = true; myTimer.AutoReset = true; XmlDocument xml = new XmlDocument (); xml.Load (AppDomain.CurrentDomain.BaseDirectory + ConfigurationManager.AppSettings [xmlfile ]); xmllist = xml.SelectNodes (/ / root / Urls / item); } void myTimer_Elapsed (object source, ElapsedEventArgs e) { try { Log.SaveNote (DateTime.Now.ToString (yyyy-MM-dd HH: mm: ss) + Heart Work,
Office Enterprise 2007 Key! (heartbeat detection )); YourTask ();} catch (Exception ee) { Log.SaveException (ee); } } void YourTask () { count ++; if (count> 10000) count = 0; for (int i = 0; i <xmllist.Count; i ++) { string url = xmllist [i]. Attributes [url]. Value; string time = xmllist [i]. Attributes [time]. Value; / / Log.SaveNote (url + - + time); DateTime workTime = DateTime.Parse (DateTime.Now.ToShortDateString () + + time); / / lastwork if (DateUtil.DateDiff (DateUtil.DateInterval.Minute, workTime, DateTime.Now) == 0) { / / to the execution time if (DateUtil.DateDiff (DateUtil.DateInterval.Minute, workTime, lastworktime)! = 0) { / / access the web site, such as mobile themes visit (url); lastworktime = DateTime.Now; } } } } void visit (string url) { HttpWebRequest myHttpWebRequest = null; HttpWebResponse myHttpWebResponse = null; Stream receiveStream = null; try { myHttpWebRequest = (HttpWebRequest) WebRequest.Create (url); myHttpWebResponse = (HttpWebResponse) myHttpWebRequest.GetResponse (); receiveStream = myHttpWebResponse.GetResponseStream ();// get back to writing the byte stream Log.SaveNote (visit: + url); } catch (Exception ex) { Log.SaveNote (access failed: + url); Log.SaveException (ex); } finally { if (receiveStream! = null) receiveStream.Close (); if (myHttpWebResponse! = null) myHttpWebResponse.Close ();} } 2) Web-side: site audit client should use mechanisms, such as a table News tables,
Microsoft Office Enterprise 2007, set field isaccept to review the field, one that has been audited, unaudited 0, add the contents of the default is not reviewed 0.
