Programming :: Regarding Query Protocol On Internet?
Jul 17, 2011
There is a protocol in use - for example when I use Firefox to do a query through Google - as I type into the search field the browser sends my characters - one at a time - to the server. As I recall, at one time I found the specification but I'm pulling a blank. As I recall it does a POST of each character as I enter it, and the server responds before I have entered a <CR>. I want to write a client side program that uses that protocol and need to see the spec.

When I set up a Virtual Machine with windows (using VMPlayer), I set the Network Connection properties from the VM settings from NAT to bridged. Then I proceed to set the following IP Properties in the OS (see image below) so that the Virtual Windows OS becomes part of my network.How do I set the same IP Properties on a Linux machine (I use CentOS) using terminal? If its any file that needs to be edited please let me know which. I wish to set up the virtual Linux machine similar to how my Virtual Windows machines are set up.

I have since switched to Fedora 12 (still on the same computer) and I realize I made a dyslexic mistake earlier, I referred to the hardware as 4537 rather than 4357. Here is the Broadcom page for Linux Wireless driver: [URL]... I've tried following the instructions in the readme in the archive but to no avail. More details on this if I try to do it exactly as it details in there. my current browser on my internet computer can't open weblocations with the git protocol.

I have created a database which stores students grades for different stages of a project. One of the stages of the project is the specification part. I have a simple bit of html code which is going to be used as the searching facility. I want the user to be able to enter their ID and then it will display only their results. At the moment, it is displaying the results for EVERY student because I cant seem to find the correct syntax for my statement.
Heres the HTML code
<html>
<head>
</head>
<body>
<body bgcolor="#6881bb">
<center>
[Code]....
At the moment when i click the button, no matter what I enter every students marks appear on the screen.
I think, but obviously dont know for sure because if i did i would know how to solve the problem, the code that i need to change is in green.

What is the code snippet required to get an image to repeat vertically up a page? I can only find info relating to repeating *background* images in my search attempts, and this is just a regular image file which I want to repeat over the pre-existing page background. I'd like it to repeat all the way up the extreme left hand edge of the page. Say the image is called abd.jpg and is in the same folder as the index.html.

So what I'm trying to do is write a USB stack for a uC, but beyond the 10 ms reset signals from the host I'm kind of lost. What happens after that? If someone could point me somewhere that explains it step by step in detail, instead of jumping around

Trying to export a Mysql query to a .csv file the query draws from multiple tables, e.g. sales, purchase and currency
Code:
What i'm trying to do is to export both the sales and purchase to a single line where both the currency for the sales and the purchase is specified.
Basically like this:
Code:
Problem here is that i'm stating currency.value twice in the same select and don't know how to define which currency.value applies to sales and which to purchase.

I need to make a daemon which listens to port 81 for messages like [URL] So far I made a daemon which serves as a simple stream server: I set up a socket to listen to a non-reserved port (like 9999), but I don't know how to read the query strings.
Linux distro: Kubuntu 9.04

It is under PHP/MySQL
$queryresult = $conn->query("INSERT INTO normalrequests VALUES($finalkey, 1234, 5678, FALSE)");
It is connected to the database successfully but I feel there is something wrong with the statement up there.

I developed a protocol "it's a modification of OLSR" for wireless networks, it was with JAVA and I try to simulate it on NS2, I used AgentJ, so in the TCL I did any thing like usual;
set val(chan) Channel/WirelessChannel ;# channel type
set val(prop)Propagation/TwoRayGround ;# radio-propagation model
set val(netif) Phy/WirelessPhy ;# network interface type
[code]....
and I didn't specified the protocol because I attached my nodes to the JAVA class responsible for the protocol, but when I run it generates errors, it claims the protocol to use, so I don't know how proceeding.

I am querying a single string column in a table. The string values have spaces in them. I want to loop over each value in bash. I set IFS to split lists on newlines instead of spaces. When I try this, it is splitting the list of results on the actual character 'n', not the newline ''.
DATA=`mysql -u root -ppassword --silent 'SELECT name FROM table_a;'`
IFS=$'
'
for i in $DATA; do
echo "item = $i"

I have written a query of commands that I made executable with chmod +x, but this is an old version of what I'm writing. I'm in need of a way to determine the Operating System the user is using so that the script will run yum or apt-get on the right OS's.

how do I achieve the result but here is the story. I have a script which prompts for the IP Address and read that value and validate if reachable. If not then it should keep on prompting until the IP is reachable. I tried using until loop as well as while loop but dang..Here are the codes
#!/bin/bash
IP_Feed () {
echo -n "Give me IP : "

If I have a Query that returns columns where some of the values are NULL, is it possible to tell SQL to return all the NULL values as empty strings instead of the NULL datatype?
If the solution is vendor specific I am (unfortunately) using a Microsoft 2008 SQL server.
Example:
Code:
Select * from imaginary_table where id = 1
Might return:
Code:
Id: 1
Name:xyz

I am not sure if this is possible. I have IP's stored in a mysql database. When I query the database, it returns the IP. I would like to replace the IP with something else prior to displaying the results. Is it possible even though I have not stored it in the database?
I have the following in a while loop (mysql_fetch_array).
Code:
<td align="left">' . $row[IP] . '</td>
Instead of displaying $row[IP] from the database, I would like it to display something else which I define in the PHP code but based on the IP.
ie. aaa.bbb.ccc.ddd = hostnameABC

So I've got a rather vast database, one of the columns is date in the following format: DD/MM/YY HH:MM:SS. This is starting to cause problems with a php page I'm writing which asks the user for a 'start date'. Would it be better for me to split the date column into date and say time? Or is there a way of using distinct and masking the times.

I have an access database and I would like to build a website on the slackware 12.2 server running apache 2.11.14 to let users query data from the MS Access database. I am thinking that I could just do it in jscript and make a jdbc connection and that should be good. What do you guys think.

I have a very strange problem in a C++ RHEL4 app. Here is the code: socket(PF_INET, SOCK_STREAM, 0) returns errno 97 socket(PF_INET, SOCK_DGRAM, 0) returns successow that is strange or what?additional info:1. Extracting the above code into a test program, both return success.2. Placing the above code into the 1st line of my app, error as above.3. I ran app and test program in the same terminal window.4. My app links in many static libraries 5. My app runs fine when compiled and linked on RHEL56. My APP is a ss7 endpoint (SIP <==> SS7 message flow)7. I verified PF_INET, SOCK_STREAM, SOCK_SGRAM values are correct.

I want to simulate a serial protocol in user space program to test reception algorithm. The protocol is similar to UART protocol but frame format is different. The duration of 1 bit is 114,46 us. In my main function I'm creating two threads. Tx for simulating transmitting data and Rx for reception data. For measure time I use create_timer() function and signals. Each thread has its own timer and signal handler. Tx timer uses SIGUSR1 and Rx timer uses SIGUSR2. Tx thread sets the global variable and Rx reads it.
The timers are set to sample with 114,46 us period. When they reach this value signal handler should set the flag. Flag is check in thread and some operation are made. When I set the timers period for longer time (100 ms) everything works fine but when I change it to default value (114,46 us) the Rx thread doesn't receive the proper data. I am wondering if the 114,46 timer period is possible to simulate in user space? Whether the time will give me the proper resolution ? Theoretically it should provide 1 ns resolution.

when I run netstat -s I get a whole listing of different statistics on udp/tcp. what I would like is to be able to understand those terms e.g. TCPLossFailures and link them with the appropriate TCP/IP terminology. There must be some refernce guide somewhere that shows what these fields mean or what they are tracking.
