you can get the messages from database by pulling it with given interval. you can create timer and append new messages in the panel. you can add panel inside UpdatePanel. You will not see any postback if you will use UpdatePanel.
You already have your answer but to explain Response.Redirect a little more: It is telling the Response object to redirect the user to the new page. What happens is the client gets that message and then requests somePage.aspx. So, it roundtrips but your C# thread will finish. It's essentially just adding a property to the Response object.
Server.Transfer will still finish your C# thread (finally will still run) but the client will not roundtrip. Execution will stay on the server and go to somePage.aspx and execute it and send the Response object back to the client.

So I separated some write functions, that update a XML file into separate classes, that generate a thread in the background to open, update and write the XML file using streamreader and streamwriter.
So I'm new to threads on vb managed code, and just found that StreamReader is not thread safe. I did some research and one MSDN article says I need to wrap the streamreader in textreader and synchronize.
I did some more research, stumbled across monitor.enter and monitor exit, and the singleton class, so that only 1 instance of the class can run at a time.
So I have a file called "Landing.xml" and I'm interested in only have 1 instance of the class work the file at a time.
Just looking for suggestions, or help with implementing. Will post code is someone asks.
Well I tried using monitor and so far so good. So I have like 15 of these class files that handle 1 xml file each, and they seem to be queuing up correctly, and waiting politely for the previous instance of itself to complete before firing again.
So the Yandex and Baidu bots have visited, and the updates were handled without error this time over the last 3 hour test period.
Well time will tell, will check the results again in the morning.
Still interested in the Singleton concept. Not quite sure how to implement it in vb
I have established a linq connexion with my database with this code behind.
And with manually set paging for 10 records.
data is shown in ListView.
How do I get the header sorting I'm using a linkbutton. Also I want to be able to insert a dropdownlist in the header. How do I receive this functionality.
With thanks in advance.
privatevoid DisplayData(int startRow)
using (Origo.Vefur.Linq.dbMainDataContext db = new Linq.dbMainDataContext(Origo.WMMain.Helpers.Global.ConnectionString))
var empList = from el in db.owm_USERs
where el.showOnWeb == 1select el;
ListView1.DataSource = empList.Skip(startRow).Take(10);
