c# - Storing Data from Forms without creating 100's of tables: ASP.NET and SQL Server -

-

Let me describe the situation first. We host several alumni during each year and provide an online registration form for each program.

  1. An event with date, time, managers, internal billing information etc.
  2. with a registration record
  3. 1 or more attendees (name , Address, degree, etc.) Information about bio / demographic and alumni data payments and payments

We expect that all the above data columns in the table we store We do.

The problem is with the 'extra' field that we put on the form. Maybe it is a dinner and there is a veggie or carnivor option, maybe there is a bed and smoking option, or maybe alternative transportation option. It is very strange in "Can you add it in this form?" The types of requests we receive

At present, we store any non-standard data in JSONify and in a column (present), which is called 'extra', we can read this data in code but it Not suitable for inquiries. Our internal staff want to generate a quick report on Veggie Dinner for example.

In addition to creating a separate table for each form containing specific 'extra' data items, is there any other approach that makes your life (and reporting) easy? Any simulator working in the environment?

This is really the most difficult problem to solve efficiently. The SQL Server Customer Advisory Team has dedicated a white paper on the subject which I highly recommend to you.

You have basically 3 options:

  • Mean database ()

Each solution comes with fluctuations from the top of my hat, I can say that XML is probably the one who gives you the best balance of power and flexibility, but the optimum solution really depends on many factors. Is the data set size, the frequency at which new features are created, the actual process (ma And operators) who use these properties, and at least your team skills set (some may be better with some EAV solutions, some may be better with XML solutions) if the features are of the Central Authority Are made / managed under and adding new features is a fairly rare event, then the rare column can be a better answer.

paypal - How to know the URL referrer in PHP? -

-
I'm new to integrating PayPal with sites, so easily from the service I can use Can the available method be? What am I trying to do, when the user clicks on "Return to my website", I want my return URL to know that the referrer is PayPal so I can send it automatically to the homepage . how to do this? I tried $ _ SERVER ['HTTP_REFERER'] but it does not seem like anything. During the IPN conversation I set the cookie and session (though I am not sure whether I am correcting it or doing this right), but on returning to my website, it does not seem to recognize any session . If I use it by using $ _ SERVER ['HTTP_REFERER'] , then I'm afraid it's a security risk, is not it? If so, is there any other way I remember? help please. Should you really know the referrer? Set the PayPal Return URL to a "secret" URL which is always redirected to the homepage. If someone reaches there and gets redirected without coming from PayPal, then ...

oauth - Facebook OAuth2 Logout does not remove fb_ cookie -

-
This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page. However, when they return to my site, I find that the FB_ cookie is still there. PHP SDK still gives user FB session details. The strange thing is that www.facebook.com shows that I am already logged out of Facebook. What can be wrong here? Thanks, I've been stumped: (. OK, finally, what did I do? > GetLogoutUrl () with a next = address url on my logout script which will remove the Facebook cookie by setSession (null) .

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...
