i'm quite new to asp.net and have been working on a simple way for users to send messages to each other....
the messages work fine, users can send and reply, however, i want a way to tell the users when they have a message and how many...
how to do this in simple terms and supply vb code if possible.
I have an MVC app that uses [Authorize] to protect the private bits. When I select the SignOut() URL it signs me out but if I hit the back button on my browser the it goes to the secure page and even lets me use the form. The action takes place and then it shows that I'm signed out. The problem is that it performs the secured action (inserting a row into my database). Then I can use the back button again and do it all over. Am I missing something important? It seems like it could be a really big security issue.

After a user creates an account on my website, I want to redirect the user to the home page and display a twitter style message bar on top. This is how I have it:
success: function (response) {
if (response.Success) {
location.href = response.ReturnUrl;
}
ShowMessageBar(response.Message);
},
The message bar does appear but it gets displayed only for a second as it gets canceled by the redirect. What can I do to display the message right after the redirect has completed? Is there a complete event for the location.href?
Without giving away specifics: basically, I have a bunch of users adding content to my site. What happens now is ajax sends the text to a web service which does its thing, sends the info to the DB, Sends the user an e-mail, and then returns a response to the browser to do something.
What I would like to do is change that order. I want to return a response to the browser so the user is not waiting on the e-mail to send before they get their response. Basically, I'm trying to gain every milisecond I can to quicken the response, and there's no reason for the user to wait for the server to send their e-mail before it tells them that everything worked ok. If the info went to the DB, that's all the user needs to know, they'll know the e-mail sent when it shows up in their inbox. I notice this is an issue on my local machine which has no SMTP server and can actually hang the page response up for a few extra seconds because it's throwing errors trying to send something with no SMTP server.
So, I know in my function when I say
[Code]....
it WORKS, but I want to send the e-mail after the return. Is there ANY way to get this to happen?
In a details or form view I have a number of entries from a database
For example:
Pass-Attempts, Passes-Completed, AvgYds, TdPercentage
If I want to perform a simple calculation on these values, and then display them in the same details/form view
Such as:
QBRating =((Passes-Completed/Pass-Attempts)*100)+(AvgYds*5)+(TDPercentage*4)
With the ideal result being:
Pass-Attempts, Passes-Completed, AvgYds, TdPercentage, QBRating on the same Details/Form view.
So basically I need to programmatically get at those values, perform calculations on them and them display them back in the same control.
This is a very common error as evidenced but the very large number of problems and suggested solutions on the web. I finally got around it last week but can't remember what was the step that did it. At that time, I was building a web application rather than a web site. Is that the difference? As you can see, it is no longer in the APP_DATA folder and is named membership.mdf rather than aspnetdb.mdf. I ran aspnet_regsql.exe to create it and actually had it working and was updating it successfully. But for other reasons, I had to scrap the application and decided to re-create it from scratch as a web site rather than a web application. I had been using Visual Studio 2008 to build the web application but am now using Visual Web Developer 2008 Express Edition to build the web site. Unfortunately, the Visual Studio application will no longer open so I can't verify that the web application still works. Can anybody help? (Please!!!) BTW, ASPNET and NETWORK SERVICE both have full control over the membership.mdf.

My web application calls a stored procedure and stores the result in a .NET datatable. I'd like to use this datatable and join it with other tables in my database. Is this possible?
Would the best way to set this up be to create another datatable and then use a dataview to join both datatables?

View 3 RepliesI have the following query:

The results look like this:
