10x. I prefer hard copy as I read it while using the morning train.
I'm looking for a new book so the questions there are supposed to be up-to-date (relatively).
It's not for a specific interview, but I love to stay sharp at these questions.
I feel it opens my mind.

Thanks for the tip, but yet I'm looking for books names.
I do it in addition to reading other professional programming books.

Exactly what I was looking 4. 10x !

BTW, how can I define and how do I use a comperator obj in c# (like in java)?
How can I apply LINQ to object to oreder according to that comperator?

Didn't mean to offend you. I should have used other words. sorry.

10x, I'll try tomorrow

I have a dictionary of

<string, <decimal,list<mytype="">>>

So the right syntax would be:
"order by item.Value.decimalfield"

?

It's more complex object:

Pair<key,value> ==> <string, dataclass=""> ==> <string, <decimal,="" list...="">>

Can I still use LINQ ?

Can I write:

"order by item.Value.percent"

?

I saw this before. I prefer .net type. If I find no such I might use that. Thanks

My Values don't have any oridinal or comparer.

1) Generally - How do I implement it?

2) Specific - I want to oreder the Values by thier "Percent" field (decimal value). Is there any "clean" syntax to do so ?

What happens if the returned value from the dataReader.GetOrdinal("BOOL_FLAG") is a DBnull value ?

The probelm wasn't the casting but catching a null value.

I don't want depend on coulmn location. This is a bad practice.

found the answer:
dataReader.NextResult() brings you the next dataTable

thanks. i have a stored procedure that returns 3 tables.
Do you know how can I read these 3 tables using dataReader?

I have wrote the c# code I needed.
Does someone know of a free server where I can host my c# code behind to work all time? (it's just one small file).

10x, what c# classes should I use in order to acquire a certain string from a given url ? I have no clue what classes and namespace could help me out.

I think I can write c# program that does that. But few questions:
1) That means my program needs to be on all the time. I was thinking of an offline service that will monitor the website also when my PC is off.

2) Is there a way of achieving that with scripts, or will it be too complicated?

the problem is that
MethodAttributes Enumeration
contains no "webMethod" value.


http://msdn.microsoft.com/en-us/library/system.reflection.methodattributes.aspx

couldn't find (1). Any way you have a quick try to help me find out ?
Found (2).

I want to create a new webMethod at runTime.
I have a user that request via POST method. I want to take his request and under some condition I want to redirect its request to a new method (useing the same POST request)

I'll try that out.
But before I do that, 2 questions:
1. can I define the new dynamic method as [WebMethod]?
2. can I Emit an instruction of putting a const value onto the stack (I want to call the statically define method with a const string as its arg0)?

My only problem is how to emit the new method's body to call a statically defined method with 3 args. (no varargs method).

Thanks. I'll read it.

runtime only.

No, but I got the solution for q1:
the regex pattern ignore domain name (from the documentation)

my main problem now is q2

10x.

Regarding the "lock"
my q: is it realy needed? because the singleton is thread safe. no?
Or just its creation is thread safe?

"Not that I know of."

How can I make sure. I could find one evnironment list that documents all the attributes.

This errorlevel is considered to be a "DOS" environment variable...
