I have a C# asp.net file upload form with a submit button. After the form is submitted the file is uploaded and post-processing is started. The point is that the post-processing can take up to several minutes.I would like to create some kind of asynchronous call of the post-processing function with showing information to the user

View 3 RepliesI have to call a function to run a report through a web service, then call another function to get the data but only after the 1st function has finished processing. How do I make c# wait till the first function has finished processing to run the second function?
my code looks something like:
NetworkCredential Cred = new NetworkCredential("uid", "pw");
ReportWebService reportService = new ReportWebService();
reportService.Credentials = Cred;
string s = reportService.runReportAsync("0ede9884e6394daf73fa418e9bffd4fc");
string report = reportService.getReportData(s);
This code will break because s is not set since the function (runreportasynch) has not finished running to produce s.
I have a function in a class file called auth_user and its in App_code folder.
I am trying to call that function from random pages that are on the website.
Inside the class file is a function that is simple, basicly check for flags in the sessions, i just wanna have it there so i dont have to type it again and again.
I want to be able to call it with one function like auth_user();
How to make a call to my WCF service asynchronous?
Here is how I am doing it
Dim wcfService = New EmailBlastService.EmailBlastServiceClient
wcfService.WCFSubCallAsync()
But when I actually do the call it seems to tie up the server for about a minute (even though I know the async process takes longer than that and is still processing the request). Even if I try to hit the page in a different browser it still takes a minute to load.
Basically I just want to make the WCF call and forget about it, I don't want users to be waiting while I am doing some heavy processing and calling an external
I'm currently working on a web site which involves a data upload process. The file is currently uploaded to the server method is called (in app_code) where ultimately a DTS package is called (via a web method) to load the data into a database and perform some validation on it.The client has specified that they don't want to have to wait for the DTS package to execute (execution time is less than 5 minutes) so it appears that I need to call the method asynchronously. The user will probably logout or close the browser window while this task is running so I believe I'm unable to run this on an asp.net thread.

I'm working on an existing web application (web site project and some class library projects). In the web site project, the guys created many web services, that are called from the aspx pages (sometimes on client side).
I need to create a new web service, so I was suggested to put it "near" the existing web services. I'm gonna need to make an asynchronous call to my new web services.
So I created the service this way, but when I try calling a method asynchronisly, I have only the method in intellisense, I don't have the method for the asynchronous call, neither the Complete event. Why is that ?
On the other hand, I created a new project, with a web service application and a web site where I added the reference to the web service, and this way I have the asynchronous method and the complete event in intellisense.
I've the following doubt. I've a page "MyPage" and i've declared few dictionary objects in the page classMy doubt isIf i declare the dictionary as a private non-static object i'm not able to use it across the functions in that page class (the object is getting nulled)able to across the object across the functions. But will that object be same across all the users who have opened the page right now (guessing that each user will have an instance of the page in turn has an instance for the page class and static variables of a class are invariable across all the instances of the class

I've created a small class library to asynchronously call a WebService(Fire and Forget. I don't need the result).In a Windows Form application, the XXXAsync() method works fine. But, in a Web Application, the process is locked until the XXXCompleted event is fire.My problem is: I tried to create a Delegate and use the Begin/EndInvoke to call the XXXAsync() method. It worked fine, but, the w3wp process seems to be consuming a huge amount of memory. I'm calling the EndInvoke method properly. Invoking the GC.Collect did not free any memory

An external server sends incoming SMS messages converted to HTTP requests into my sometimes very time-consuming .aspx page. If no response is returned to the external server in 20 seconds, this is considered as an timeout and the same message is sent to my aspx page again (and maybe again....The optimal solution for me would be that the aspx page reads the incoming message (as an HTTP request to the aspx page), starts the processing of the message in another thread, and immediately renders response back to the external server. The external server has no interest in other stuff than the HTTP status (normally 200). When the processing of the message is completed this results in an entry into the log file of the application.

I don't know how to apply this scenario:
Senerio 1:
1- run Asynchronous function to export data from SQL for specified period to CSV file (without locking the table)
2- Refresh page every 5 sec in order to track the status of extracting data
3- compress the file
4- Stop refreshing and showing the download link in order to download the compressed file

I have a try-catch inside a method that is called asynchronously. When an error occurs, inside the catch I have a Response.Redirect because I need to redirect to the login page.
This is my issue.
But my problem doesn't involve things that expire, so the idea of a timer isn't the best way to resolve it.

I am using a third party service for location time(zonal).If I pass latitude and longitude of the location with service URL it returns the time of that location in XML format.But the problem is some of the time this service gets too much slow so because of that my home page gets stuck because its a synchronous call of that service.here my code-
string TimeZoneUrl = "http://ws.geonames.org/timezone?";
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(TimeZoneUrl + "lat=" + latitude + "&lng=" + longitude);
XmlElement root = xmlDoc.DocumentElement;
XmlNodeList nodes = root.SelectNodes("//*");

I am building a page with databound list control. For each row I want to display piece of info retrieved from web service call. This could be time demanding so I want to render page first and retrieved additional info asynchronously and in parallel later on. Anyone has some tips how to make it? Just to have a more detailed picture it is a product list in e-shop which I want to render so customers can use it (go to product detail/add goods to shopping cart...) but meantime there will be a placeholder displaying info that informations are retrieving which after completion of call will be replaced by result data.
