is there a way in c# to be able to ping a url every 15 minutes and get a response back from the server?
i want to try to see if .net can be used to build a simple tool to have asp.net websites invoke a re-build so that the first user doesn't incur the load penalty when the application is started.

I want to redirect the user after 2 mins if there is inactivity for 2 mins. I am not using ASP.NEt membership. And I dont want to use Sessiontimeout for this. Session timeout will logout the user even if he is working on the system. My objective is like screensaver process.
If there is no action for the specified time, the screensaver runs. Similarly, I want to redirect the user to login page.
note that i have already handled it with the following javascript:
[Code]....
Here what my problem is,
the user is working on the site...ok.. he want to see someother site.he browse someother site and works on....or even he can do some other work in his system...but he is active in his system... What this script does is, it automatically logout the user and redirect him to login page. But it should not do while he is active...IT SHOULD REDIRECT IF HE IS NOT ACTIVE REALLY (Similar to Screensaver process)
Is it possible ?
I got a strange issue after hosting the my site in IIS 7.5, Windows server 2008 64 bit
The applicaion is created in ASP.Net 2.0
The page with issue has following workflow:
Upload a file from browser (may be very large size ~50 MB)Perform some process (May take very long time: up to 30 minuits)Notifies the client that process is done.During the process client uses something like http://www.codeproject.com/KB/session/Session_Defibrillator.aspx to keep the session alive.
The Issue:
The client does not get any response sent by my code after the process is over. It should refresh the page with the response provided by my code. But instead it only shows waiting for... in the status bar.
I have tried this on IE and firefox.
To veryfy the process is over
I have added some trance message in my code to check when the process gets finished.I have also checked the Log from IIS, it also shows that response sent with Code 200.
Please help me solving this issue:
What could be the issue?How can I diagnose and fix this problem?In what cases connection between browser and IIS server gets lost.
I used the following code for the form download
[Code]....
But form is not posting back on execution of the above statement. What should I do , so that form postback also occurs after this statement.
Does a response.Redirect first postback to the page that's calling the redirect before actually redirecting? I don't think so but my debugging is showing me that it is.
I can see it doing so and that causes me a problem. The problem is this:
1) My page has an asp.net button on it
2) When the button is clicked, the page posts back of course. Then the following is called in the event handler method for that button:
Response.Redirect("Checkout?frpp=1"), true);
3) But I notice that when the redirect is called, it first goes back and hits the page load for this page, the page that's doing the redirecting. Well that is causing me problems because it's calling code that I don't want it to be calling again such as this:
if (!IsPostBackl)
ShowOrderItems();
so it's like I'm doing a 2nd postback:
first postback happens when you click the button, hits the event handler, runs my handler method which calls the Redirect. Redirect is called but it's doing another postback to the same page here..why?
I have a webservice that sends the response back in XML format.I'm able to connect and call the webservice adding an external web reference to the Visual Studio project.Then in my code behind:As New servicename_addedLabel1.Text = servicename_added.Functionexposed(param1, param2, etc)With that code I can get the response in a large label and unstructured data. If I "view source" I see the XML structured data.I have tried to create an XML document without success.My goal is to parse the response and write it to a database separating all the fields.
View 5 RepliesMy web site is integrated into a client web site. Client web site reaches out to my site through an Xml request and I return Html embedded in an Xml response. Client site then displays the Html in an area on a page on their site. All is well so far...
Now, there is a link on the Html that does an HttpPost back to my site which causes a re-direct to another page on my site. i.e. [URL] -> HttpPost -> [URL]-> Response.Redirect("CookieTest.aspx"). Still, all is well. [URL]
All of the above can occur without authentication to mysite. Where I start running into problems is when CookieTest wants to do a FormsAuthentication.SetAuthCookie(). If I put a button on CookieTest that does FormsAuthentication.SetAuthCookie() and then Response.Redirect("SecurePage.aspx"), still under [URL], the SecurePage does not recognize the authentication because the auth cookie is not present.
1. Navigate straight to CookieTest.aspx
So I simplfied the problem into basic cookie set/read excercise and used the code below to test out cookie writing/reading ability. When I call the page directly from the browser I see that on initial load the response cookies are empty. Then on button click I see that the cookie is properly set in the response. Then on subsequent page refresh I see that the page load shows the request cookie.
2. Navigate to CookieTest.aspx in an HttpPost from [URL], as mentioned above.
Now on button click I see the cookie in the Response but do not see it come back in the Request of subsequent page refreshes, as if the client browser is rejecting cookies set by my server.
3. Navigate straight to CookieTest.aspx, then do the HttpPost from [URL]
In this case, since the cookie was set during a straight navigation to CookieTest.aspx, the cookie is present in the subsequent HttpPost/Redirect from [URL]. CookieTest.aspx has full access to the cookie and can even delete it.
4. Have CookieTest.aspx pop a new browser window simply sets the cookie and closes itself down.
Similar to #3, if the cookie is set through a popup window and then CookieTest is refreshed the cookie is present in the Request.
Notes:
The code does prove that the client browser accepts cookies.
When my page (CookieTest.aspx) is shown within the frame on the [URl] page, during any link back to my server, the Request.Url.Host shows my domain.

Im using asp.net c# (webforms) I want to add a back button to my page. (you land on this page if you incorrectly fill in a form). if javascript is enabled i want to go back via javascript, but if it is disabled i'll just do a response.redirect("~/home.aspx"). how can i implement this? is it 2 buttons? how can i hide the other in the 2 different states if so.
View 2 RepliesI have a button that when clicked, will generate a PDF and write it out to the response.This is the basic structure of the code:

[code]...
Downloading the file works fine, except that it doesn't complete the postback.If I were to throw an exception above file.Transmit, the error handling would work properly and I would see the message get displayed in my browser. However, if there is an exception after the file.Transmit then nothing happens. The user saves/opens the pdf and the page does not reload.How can I make it so that the postback always completes, that way I can display an appropriate message to the user?
What I have?I have a ASP.NET page which allows the user to download file a on a button click. User can select the file he wants from a list of available files (RadioButtonList) and clicks on download button to download it. (I should not provide link for each file that can be downloaded - this is the requirement).What I want?I want the user to download multiple files one by one by selecting the required radio button and clicking on the button.What problem am I facing?I can download the file for the first time properly. But, after downloading, if I select some other file and click on the button to download it, click event of the button does not post back and the second file will not be downloaded.I use the follwoing code on the button click event:
protected void btnDownload_Click(object sender, EventArgs e)
{
string viewXml = exporter.Export();
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=views.cov");
Response.AddHeader("Content-Length", viewXml.Length.ToString());
Response.ContentType = "text/plain";
Response.Write(viewXml);
Response.End();
}
I have 2 datetime columns:
Date1 = 10/1/2010 11:00:00 PM
Date2 = 10/2/2010 1:00:00 AM

Date1 - Date2 = 120
How can I do this?

I have inherited a stored procedure that is taking a very long time to run. I need to optimise this as it feeds a web service and a wait time of over half an hour is somewhat not good.

I have not includes all 1000 sub-accounts just to save a little space here.
The constraints on the table variables are my doing as I was seeing if applying such primary keys / indexes would help matters, but they haven't so far.
So we have three 2008 R2 Servers where two are configured to be web servers (IIS 7.5), and the third a session state server. I have set the SessionState and MachineKey settings in the applications web.config. After I restart the two web servers I can log into one server, then change the IP address to the other server, and I am still logged in. Success.
I can typically log in/out with any user account I want, change the ip address back and forth, and all is well until some random time between 30-60 minutes when I log in to one server, change the IP address, and the new server asks for credentials.
This is the sessionState setting in both web.configs:
<sessionState mode="StateServer" stateConnectionString="tcpip=xxx.xxx.xxx.xxx:42424" cookieless="false" timeout="30"/>
The application resides under the default web site, and uses the default application pool. I am using forms authentication with a timeout of 20 minutes. I am not receiving any error events on any of the three servers when this happens, and restarting the two web servers fixes the problem for a while. The two web servers are not clustered per-se, but will be served round-robin via a network device.

i have a forms application which pings all the network machines. this works fine and also returns the status of each machine i.e. sucess, timeout etc. however i also want to get the name of the remote machines so i use this code:
[Code]....
the above code works fine however any exception is given when the remote machine is a mac. the exception is:
[Code]....
how can i counter the exception so that it simply ignores the exception and carries on the for loop for the other machines.
I have to execute a stored procedure. When I execute that, I have to keep on check (ping) whether that execution is completed or not. The I will update a label.
Do we have any way in c# to do that?

View 4 RepliesBeing new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.
