Wrong place to ask - it even says so at the top of the page in red letters!

And don't call your tables by SQL Reserved words: "Table" is either not the name of where you store that info, or you should change it. Not only is "Table" a reserved word, it tells nobody anythign about what kind of data it contains, and that's kinda important ...
Fix that, and your problem will go away.

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
For n = 1To10
I 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
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.
