Updating or inserting entities using Entity Framework

Hi All,

I have an Asp.Net application in which I am trying to insert/upate a database table in the backend. But I am getting following message.

Unable to update the EntitySet 'message' because it has a DefiningQuery and no <insertfunction> element exists in the <modificationfunctionmapping> element to support the current operation.

Can anybody help me please by giving any suggestions, links or code snippet. Mean time I will be googling about the exception.

Thanks in advance.

Thanks & Regards,

Page.ResolveUrl and reverse proxy

Hi,

I've got an issue with Page.ResolveUrl and an ISA reverse proxy.

We've got an internal webserver that hosts multiple webapplications. The are therefore configured as applications.

Let's say we have:

http://internalserver/applicationX

By using an ISA2006 server this adres is being reverseproxy'd to:

https://subdomain.myorg.com

If i put this in my page
<script src="<%= Page.ResolveUrl("~/MicrosoftAjax.js") %>" ></script>

it wil stil resolve into
https://subdomain.myorg.com/applicationX/MicrosoftAjax.js

Is there a way to make .NET aware that it a reverse proxy is changing the path?

Or should the reverse-proxy solve this?

Kind regards,
Sebastiaan

For starters, don't put repetitive server code in a web application because then you will need something to trigger the process anyway.
Why not investigate using a Windows Service or an application that is setup to be run by the Windows Task Scheduler.

I wasn't, now I am, then I won't be anymore.

The best way to do this is by writing a windows service and run it on the server. this windows service can be written in such a way that it will do some particular task every hour.

In that case, I will have to suggest a very very dirty workaround for tackling this problem.

1. Have a page that will do the required task. do the required task only when a specific query string is present. This way you will ensure that only you know this actual link that will perform this operation.

2. Now whenever you access this page with this specific query string this task will run. you can do it manually but you can still automate it. lets see how:

3. create a simple winform application with webbrowser control in it and navigate it to the required page with the specific querystring. all hard coded in the page_load. so when application opens up your task is done. close this app in webbrowser navigated event.

4. Now configure a windows service on your PC that will run this application on a specified time.

P.S. all this assuming that the task you need to perform is not time consuming otherwise you will get timeout problem.

Note: I am not recommending this approach. it is very very bad. but in desperate times such workarounds do work.

Is this a task SQL server based?

maybe you could write a SQL job and have it scheduled. (if your hosting agreement allows it)

Just a thought.

As you are using shared hosting, it is not possible to connect to windows service as this will not be allowed.

Create a web page which will do the task (as per your requirement - say adding some data or sending mail etc). Use query string to specify your parameters. Don't forget to encrypt the querystring value for security concern.

Now the interesting thing, create a windows service in your local machine which calls the above mentioned aspx page with querystring value.
Thus the page is fired in background and the code behind of the page will do the rest.

Thanks,
Sandip

Hi All,

I have an ASP.Net application and a WCF Service running on the same machine in IIS7. My machine name is "mmmmmmm250D" my user name is "uuuuuuu250". When I am running my applications(asp.net and wcf service), I am seeing that these applications are running under the user account "<domainname>\<machinename>$". This is taken automatically. This account is assigned when ApplicationPoolIdentity is "LocalSystem" and "NetworkService" in both the cases.
Is there any way that I can make these applications to run under my user account as I am admin for this machine where IIS is installed. The applications should run under account looks like "<domainname>\uuuuuuu250". Please help me I am struggling with this for a while.

Thanks in advance.

Interactive Chart - Write Back to Database

Member 936975420-Aug-12 7:56

Hi,

I want to display some fairly simple graphs and charts. For example, horizontal bar chart with 25 bars.

Then, I want a user to have the ability to resort the bars and upon completion (click event on button or something) write the results back to a database.

Here's an example: List 10 car companies in a bar chart (horizontal) from 1 to 10. User thinks that the car company at 8 should be ranked #3. They move the bar to the #3 spot and the bar at #3 goes to #8. User is done and clicks "Submit". Now create a unique id for this session and write to a database.

Can anyone tell me what tools/languages would work well with this?

Thanks for your responses!

I don't know who downvoted this, but I have voted you back up. Whoever it was their rep was small, so my upvote will more than counter.

First, jquery alone can't do this for you, it needs to get the information from the server (assuming the files are on the server). You'll need to do some googling as a full solution will take time but:

On the server you need to create a JSON result with the paths of the files
On the client side you need to use jQuery's ajax/[^] function to get the information

As you are using AJAX I'd suggest the server responds with the next Image url (don't forget loops round at the end). This means the Client needs to send the current url (or some identifier) so the server knows where the client is in the list. If an empty or unknown url is passed to the server, return the first element, that way the slideshow can bootstrap itself easily. If you are using MVC3/4 the server component is easy, these can return a JSON result directly. With ASP.NET webforms, it is a little harder (see http://stackoverflow.com/questions/2422983/returning-json-object-from-an-asp-net-page[^]) but not very hard.

There is a reasonable amount of work in all this, it might be worth getting one of the many on-line sliders and taking them apart to see how they work (or just using them if one fits!).

There seems to be a trick with javascript, see http://forums.asp.net/p/1132444/1806386.aspx[^].
But I'd also mark the cookies expired, and check for valid cookies on every page. Also use no-cache and expires directives for every page.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
