C# - What Is The Preferred Method To Manage A Timed Event With A Web Application
Sep 28, 2010
I'm designing an ASP.NET 4.0 Web application where administrators may create an auction with an expiration. The expiration time would be stored in a database. How can I ensure that the auction ends at the predetermined time, considering the fact that an application instance may not be running when it is time? The application will be hosted with IIS7. I am considering Windows service, but I am wondering what other options are out there.

- I have a situation in which I must execute a dynamically built stored procedure against tables that may, or may not be in the database. The data retrieved is then shunted to a VB.Net backed ASP based report page. By design, if the tables are not present in the database, the relevant data is automatically hidden on the report page. Currently, I'm doing this by checking for the inevitable error, and hiding the div in the catch block. A bit kludgy, but it worked. I can't include the VB code-behind, but the relevant stored procedure is included below.
However, a problem with this method was recently brought to my attention when, for no apparent reason, the div was being hidden even though the proper data was available. As it turned out, the user trying to select the table in the dynamic SQL call didn't have the proper select permissions, an easy enough fix once I could track it down. So, two fold question. First and foremost - is there a better way to check for a missing table than through catching the error in the VB.Net codebehind? All things considered, I'd rather save the error checking for an actual error. Secondly, is there a preferred method to squirrel out a particular OLE DB error out of the general object caught by the try->catch block other than just checking the actual stack trace string?
SQL Query - The main gist of the code is that, due to the design of the database, I have to determine the name of the actual table being targeted manually. The database records jobs in a single table, but each job also gets its own table for processing data on the items processed in that job, and it's data from those tables I have to retrieve. Absolutely nothing I can do about this setup, unfortunately.
DECLARE @sql NVarChar(Max),
@params NVarChar(Max),
@where NVarChar(Max)
-- Retained for live testing of stored procedure.
-- DECLARE @Table NvarChar(255) SET @Table = N'tblMSGExportMessage_10000'
-- DECLARE @AcctID Integer SET @AcctID = 10000
-- DECLARE @Type Integer SET @Type = 0 -- 0 = Errors only, 1 = All Messages
-- DECLARE @Count Integer
-- Sets our parameters for our two dynamic SQL calls.
SELECT @params = N'@MsgExportAccount INT, @cnt INT OUTPUT'
-- Sets our where clause dependent upon whether we want all results or just errors............................

I get this error "The server method xxx timed out." calling a WebService that internally does a hard query to the database, and takes some time. I use this method to change the webservice timeout, but it does not seems to do anything (the timeout errors appears in less than a second).
MyService.set_timeout(100000);

i like to design a asp.net application(app1) where we can create role and actions. here action is such as create student details and delete student details... this both actions comes underneath to a role1.. so, the application will have some roles with set of actions. This roles and action will be used later in another applications(app2 and app3).
i have designed app1 with single sign on for all the application(app2,app3). when a user enter into app2, he/she will be redirected login page which resides in app1. There user validation will take place. once validated, authentication ticket will be send back to requested application(app2).
Once app2 receive the ticket, it will make another request app1 to get the roles and action belongs to singed user. the app2 should behave based the actions belongs to role.
*A user can have more roles.
how to control the user activities based on the actions?
Is there any framework to achieve this model?

I want to create a multi-tenant application that uses the hostname to determine the customer.
For example:
CustomerOne.myapp.com
AnotherCo.myapp.com
AndOneMore.myapp.com
I can do the database and security side with no problems, I can also get the hostname from the URL, but what I am struggling to find out is how to create the basic plumbing that would allow a new customer to sign up online, provide their company name, and for the application to create the new URL, ready to be used straight away.

I am working on an application that resides on a development server on our internal network. The application was originally written to use Membership and Roles. We got busy almost a year ago before the app was finished, and now we are trying to get it ready to use internally.
The login page works just fine, but I have lost the ability to controls users and roles. I am running Visual Studio 2010 Professional now on a Windows 7 VM. I can open the application fine but there is no Web Administration Tool available for me to manage users or roles. If I go to Website -> in Visual Studio, there is no option for ASP.NET Configuration in the drop down menu. It simply isn't there.
How can I regain access to manage users and roles for this application? We are using Forms authentication and the database resides on a SQL Server 2005 instance on a separate box from the web server and my local VM.

I have Web Application which uses the Logged In User (Authenticated User) to query his Profile Data from Adabas/Unix using OLEDB. The application provides the user with about 21 different pages (Basic Info, Employment Info, Education, Dependants, Financial Info ...).
The web application has a master page, and each profile data page is based on a User Control loaded in the Child ASPX Page.
The Data Layer of this Web Application will have to undergo major modification, since we are migrating our legacy applications from Adabas/Unix to SAP, the development Team has prepared web services to query for the same Profile Data from SAP using Web Services. Now, we have to modify the web application to consume the web services instead of using OLEDB to query Adabas.
Since we are in the testing phase, and we have only very limited data in SAP, I have to provide temporary control to allow test query the Staff Profile for a Specified User (instead of the Authenticated User) and to select the Source:
1. SAP, or
2. Adabas.
So I am thinking to add the following "Control Section" in the Master Page:
[Code]....
See image below to clarify:
[URL]
Becuase the users defined in SAP are based on Dummy Data, so we want to allow the user to Enter the required SAP User, and he will select "SAP" from the Drop-Down-List. In this case, the program will query for Staff Profile Data from SAP for the specified "Staff ID" (txtSAPStaffID) instead of the Authenticated User. But, if "Adabas" is selected for the "ddlDataSource" then, it will default to the Authenticated User.
I noticed that when I am following the above technique, if I press "Go", the Staff Profile Data Page is disappeared, and when I navigate from page to another, the selection on the values entered in the "Control Section" in the master page are reset to default value, ie, the last values are not maintained.
Questions:
1. What is your feedback on the method I followed above ? Any other recommendations? I need very simple method.
2. Why the data page (the child page of the master page) is cleared (disappears) when I press the Go button ?
3. How to maintain the values selected when I navigate from one page to another ?

I'm planning to set up an online store for a friend, unfortunately his product line introduces some demands most out-of-the-box solutions don't fit. I'm hoping somebody here has had some experiences with an open source package that they can recommend. The specific issue is that the products are going to number in the hundreds of thousands. Since the type of products have a lot of clearly defined specifics, searching and sorting can be (and needs to be) very granular and efficient. For this reason, the primary requirement is that I replace the product and search-related parts of the app, but only those parts. I'm hoping that there's an ecommerce solution with the product segment abstracted so that I can change the database tables, product display code, search code, and create the obvious code to interact with the database.
I'd prefer something that's built on ASP.Net MVC since it'll play nicely with some extensions I am considering for the future but I'd consider WebForms. I'd also like it to be something that functions on GoDaddy's Hosting, though I'm not optimistic, I just got the account before I discovered how terrible of an ASP.Net web host they are. And finally I need something that's reasonably mature as I don't have time up front to deal with a system that hasn't been tested, and the majority of issues worked through already.

In an ASP.NET website, how would I run a process, such as send an email, on a timed interval?
Lets say send myself an email every 4 hours. And assume there is no activity at all on the website during that period.
The only way I can think of doin it is open a web page on the site and have it refresh at a timed interval that is less than the server time out setting. When the page refreshes check to see if it is time to send the email, if so send it.

This is my base class for all pages except EndSession.aspx
override protected void OnInit(EventArgs e) {
base.OnInit(e);
if (Context.Session != null)
{
//check the IsNewSession value, this will tell us if the session has been reset.
[Code]....
But on EndSession I try to navigate back to, say default.aspx, and then this code above just redirects be back to EndSession.aspx.
So for better clarification:
Step 1: Go to mypage.aspx
Step 2: Wait for timeout
Step 3: try to navigate away
Step 4: get redirected to EndSession.aspx
Step 5: try to navigate away
Step 6: GoTo set 4
Setp 6 should be actually being able to navigate away...

There is no way I'm the only one who thinks that I'm missing such a shortcut in Visual Studio.In the markup (aspx) I begin writing the event name "On..." then choose the event I need. What I'm looking for now is functionality for auto-inserting the event name and the delegate method in the codebehined exactly as it's done from the Design view.It's a simple and very helpful functionality that's obviously missing - or I havn't been able to localize it yet.Does any one know if it can be done in VS? Maybe using ReSharper?
