You could do this:
c = new OleDbCommand("Create Table " + textbox1.Text + " (name char(10), surname char(10), age integer, phone char(12), email char(20))",s);

or this:

c = new OleDbCommand("Create Table ? (name char(10),surname char(10), age integer, phone char(12), email char(20))",s);
c.Parameters.Add("table",textbox1.Text);

HTTP has been In use by the WWW global Information Initiative since 1990 and nowadays It Is one of the most widely used protocols on the Internet
HTTP application have historically allowed three different formats for the representation of date/time stamps (described In RFC 2616)
1. RFC 1123 format, for example
Sun, 06 Nov 2005 08:49:37 GMT
2. RFC 1036 format, for example
Sunday, 06-Nov-05 08:49:37 GMT
3. ANSI C's asctime() format, for example
Sun Nov 6 08:49:37 2005

An Implementation Is not HTTP 1.1 compliant If It fails to understand one of the above date/time formats

Question 1
You are require to write an HTTP 1.1 compliant program to parse a string containing one of the above date/time formats. The program must detect the date/time format automatically based on the Input string and store the result In the following object
Class MyDate
{
public Int day; /*1 to 31*/
public Int month; /*1 to 12*/
public Int year; /*1970 to 9999*/
public Int hour; /*0 to 23*/
public Int minute; /*0 to 59*/
public Int second; /*0 to 59*/
public Int dayofweek; /* 0= Sun, 1=Mon,etc* /

}
Question 2
Develop a program to display the system date/time In the RFC 1123 format(as show In example)
=====================================================
I have no idea to do this exercise, please help me.
Thanks alot.
Good luck.

Hence why you are given homework, so that you can learn. If you are totally stuck on where to start can I sugggest you either a) Attend your classes and/or b) Seek advice from your tutor.

Voted 1 because:

a) we don't do your homework for you
b) you've posted this before
c) the problem is really neither interesting or all that advanced

If you're really stuck start with the MSDN documentation for the string class. You might also find the Regex class and the DateTime class useful.
Show that you are actually making an effort and somebody can problem help you with specific problems.

I would have to say that the most interesting aspect to this post is that you are a 3rd year computer student and yet you do not know how to parse a string. By my third year I was writing compilers and operating systems. I highly recommend you consider a new career path. We definitely don't need more developers like you around. You got a 1 vote from me.

I already have attributes in the app settings part of the file. For these particular att. I need to extract their values and put them into an array.

The number of attributes is not static so I cannot place them in an array using their keys.

Is there any other way???.

Hi
I am trying to create a socket for listening form my machine as a server.
Could somebody tell me why there is an exception "An invalid argument was supplied" in the last line below?

IPHostEntry ipHostInfo = Dns.Resolve(Dns.GetHostName());
IPAddress ipAddress = ipHostInfo.AddressList[0];

IPEndPoint localEndPoint = new IPEndPoint(ipAddress,myPort);

Socket listener = new Socket(AddressFamily.InterNetwork,
aSocketType.Stream, ProtocolType.Tcp);
listener.Bind(localEndPoint);
Socket acceptedSocket=listener.Accept();

Thanks
