I have a if statement and a table with 2 atributes. They are description and date. I will check if there is in the table some date like 01-01-2008.
String test "01-01-2008";
if (test.Equals(here I will a SELECT query like SELECT date FROM appointmentTable))
{
textbox1.text = "The description on this date is: " + Here I will the descripton of the selected date
}
Does someone know how I can make something like this in C#?

You need to do the select statement first, then you can compare the data that comes out. You probably want them both to be date time objects, so you compare the dates and not their string representation.

There is a screen that appears before a user logs off.
He has to choose whether to log off or switch user.
Or it can be the screen of log off / shut down and etc.
I want to perform some code before this screen appears.
How can I register to the event ?
Thanks,
Clint

are you kididng it must be some way to compile it like working with bits and bytes ore such ...
or some lists,arrays, ....

Why would I be kididng [sic]? You asked whether variables names that begin with a number are valid. I suggested that you tried it and observed what happened. You tried it and found that it didn't work. By following an empirical approach, you have answered your own question.

This sentence is nonsense. I have no idea what you are talking about.

You lose.
Not even with the @ identifier specifier does it work:
int @int = 1;
int @1name = 1;
An identifier in C# can never ever start with a digit.

Bonus question: can identifier start with digit in IL? (I gave up after maybe 2 min. of googling  )

I hope you didn't bet too much, or you could end up buying your teacher a Porsche. He's right, and you're wrong. Variables can't start with a number as you found out when you tried to compile it.

but if i enum ??
enum(1a,2a,3a,4a,5a)

Enum members are not variables, and even those identifier cannot start with a number.
Had you tried it yourself, you would have found out quite easily.
But, in either case, you still lose...

My sympathys are with your teacher. You don't listen to him, and you still haven't learned your lesson.

But not this one.

You are ninety-two feet? Or did you perhaps mean '92?

Oh, a newbie.

Go figure...

That's good. Pascal is an excellent language for learning programming.
conemajstor wrote: becaues my teacher is 65 years old and dont know anything other
I seriously doubt that.

So now you think that you know anything?

There's nothing wrong with being 65. Unless you're the leader of the British Liberal Democrats...

You really need to listen. If he's your teacher, he's better than you. Usually, but now, duh. Period.
The most knowledge doesn't mean the most wise...

Sorry, but it's not valid in Pascal, either.

You could always... cheat.
Fonts, all they are a little pictures really. What is it, courier new that compilers mostly use?
Anyway, see if you can get yourself that font, edit out some symbol that is allowed, and make it a number.
To the user, the first letter in the variable name is a number, but to the compiler its just a symbol, or another letter.
Oh, by the way, cheating is bad. Don't do it
