This is a rare example of a question which isn't vulnerable to SQL Injection. Bobby Tables doesn't apply here.

You are of course entirely right. I'd read the code and my brain screamed "this is so wrong" so loudly that I overlooked the parameters...

Never use SQL in your production code. Always use stored procedures and pass in parameters where necessary. This is one of the ways hackers use to SQL inject your code.

You can use parameters without stored procedures.

That wasn't the point I was making. It was about avoiding SQL injection and using stored procedures instead of passing SQL over the wire in your code.

Well, certainly seemed like that.

That's unrelated to Stored Procedures.

Well, if your application server isn't on the same network as the database, you're having much bigger problems.

Like many developers, we use third-party providers for our hosting requirements. This includes our application and database. They are hosted independently on separate Azure instances (and in separate geographic regions). Having the two hosted on separate servers is neither unusual nor a problem.
Using a stored procedure to initiate a CRUD operation allows you to reduce the likelihood of a SQL injection attack as you are not passing raw SQL statements over the wire from the application to the database.
Don't just take my word for it, this is the advice given by many articles for reducing the problem.

People who say "never" and "always" tend to be wrong a lot.

Not in this case.

Not half as tough as England will be playing!
The All Blacks are on fire this year ... 
And we barely scraped through.

We were not very good at all Paul hopefully WG will have a hard word before the South Africa game - a wins a win though we had Warburton sent off in 2011 and France beat us

There is a bloody great big frog getting an earful for the red card that cost them the match. Japan match was a real grind for the first 50 minutes before the weight of SA took its toll.
Looking forward to seeing the Kiwis give the dammed poms a hard time.

I'm Welsh and would love them to win but they won't unless they shape up.

We played much better than Wales, as even Wales coach admitted, but in the end with the two missed penalties and that red card (Our guy must be brainless to do something like this at all, let alone in a world cup) and a bit of technical errors in front of Wales line, we did no make it. Anyway, it was a nice game, and I enjoyed watching it.

I just spent over an hour fixing some custom DateTime TextBox that only worked if the system clock was in a specific Dutch format (both CurrentCulture and CurrentUICulture had to match) 
I'm sure it all works at the customer (for now), but as a developer I prefer having my OS in English because it's more Googleable.
And I REALLY don't know what to make of this 
smtp.Send(mail)
For n = 1 To 10
Thread.Sleep(500)
Application.DoEvents()
NextI wanted to apply the boy scout rule, but that's a full time job
There's new work (and a new customer) in it for me though.
Probably a new web or mobile application hosted in Azure

Application.DoEvents() is used to keep a Winforms GUI responsive, otherwise in a tight loop it will freeze.
Agree with you on the English Windows version, just can't stand Windows Dutch translation 
|
|

I know what DoEvents does, but why would you need it in the first place?
And in a loop?
With a Thread.Sleep?
I should add that the class in which it is used is not even a Form.

My bet is that the SMTP method runs asynchronously and they wanted to make sure it goes through before the code goes on.
Could be worse, I've inherited a code base that crashes when compiled in release build, works only in debug build. Thankfully, I am rid of it now.

Then he should put that send mail call in an async method and prevent user from sending another mail or closing the program before it's done.
