Data structure for quick time interval look up -

-

I have a set of time interval in = (a, bn) I have a lot of lookups Need to run where I T is given at one time and the need to quickly return those gaps in which t , such as those intervals like A & lt; = T & lt; = Bn .

What is a good data structure or algorithm for this?

If it matters, in my case a and BN are integers.

There is one for what you are looking for (which is of one type).

These are logarithmic lookup times such as other tree structures (e.g., RB trees), so you should see comparable performance to use something like JavaTrinmark or a STL map.

asp.net - Javascript/DOM Why is does my form not support submit()? -

-
This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
