WAMP and IIS

If both WAMP and IIS7 are installed, IIS7 will be displayed.

To solve this problem, do this:

WAMP to run on http://localhost:8080/
IIS7 to run on http://localhost/ (no change)

To change WAMP,
click on WAMP Server icon on taskbar and go to Apache > httpd.conf

Change ‘Listen 80’ to ‘Listen 8080’ (As shown in the screenshot). Save and restart WAMP.

Reference:
http://www.programmerfish.com/how-to-run-wamp-server-parallel-with-iis-7-on-windows/

Now WAMP Server is accessible on http://localhost:8080/

Added Note:

With above change only, I have to manually enter 8080 to "http://localhost/"
I am going to edit the same file, "httpd.conf" file.

Original:
#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName localhost:80

Changed:

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName localhost:8080

This did NOT do anything.
Put back the original setting.

Change it back to:Listen 80
(it was changed to "Listen 8080")
Then, DO this, instead!

Theory, you can have both, but IIS and Apache/Wamp are both web server and might conflict in some way, so you have to disable IIS in order for Wamp to work

Disable IIS in Vista:

Control Panel, Uninstall Programs, Turn Widows Features On or Off, uncheck Internet Information Services

In the I"Uninstall or Change Program" window, click "repair" icon, then uncheck "Internet Information Services".

visual studio 2010 C++ note

Problem: start without debugging missing in visual studio 2010 C++
When use ctrl-F5, it automatically closes console window.

To fix this, do the following:

right click the project name,
go to Properties page,
expand Configuration Properties -> Linker -> System,
select Console (/SUBSYSTEM:CONSOLE) in SubSystem dropdown.

There is no start without debugging icon, so only way to active it is ctrl-F5.

php - working with files (4)

It reads a text file.
Make the first line title, and print.
Remove the line.
Using nl1br(), converting text line breaker to the tag,
print the rest.

<body>
<?php

// read file
$data=file('C:\wamp\www\testFolder\tetsuro\tetsuroP04_php_file3\omelette.txt')
or die('Could not read file!');

/* first line is title. read it into variable */
$title=$data[0];

// remove first line from array
array_shift($data);
?>

<h2><?php echo $title; ?></h2>

<?php

//
// nl2br() function converts regular text linebreaks
// into the HTML equivalent, the tag.
//

/* iterate over content and print it */
foreach($data as $line){
echo nl2br($line);
