PHP Mail Message - Line Break Problem

2010-10-23T10:33:00.000-07:00

I realized that PHP doesn’t parse neither \n nor \n\r to their corresponding ascii characters after several attempts.So use
char(10)
where you want to insert a line break.

caps:

problem:
$text_cfm = 'Hi '. $name. ' ,\nThanks for your interest';

output:
Hi Nuri ,\nThanks for your interest

solution:
$text_cfm = 'Hi '. $name. ' ,'.chr(10).'Thanks for your interest';

output:
Hi Nuri ,
Thanks for your interest

How to install your Red5 application on Red5 server

2010-07-15T09:43:00.000-07:00

I assume that you have already prepared your red5 application and application file structure, and also assume you are using eclipse, win xp, red5 0.9.1

1 - Create a new folder under C:\Program Files\Red5\webapps named yourapp, and copy your WEB-INF folder under C:\Program Files\Red5\webapps\yourapp, then create a new folder under C:\Program Files\Red5\webapps\yourapp\WEB-INF named lib.

2 - In Eclipse go to File->Export, expand Java and select JAR file. Hit Next. Under "select the resources...", expand your app and select WEB-INF. Also check "Export java source files and resources". Set export destination to C:\Program Files/Red5/webapps/yourapp/WEB-INF/lib/yourapp.jar, hit finish.(thanks sewerewes)

3 - Go to C:\Program Files\Red5\ right click red5.jar -> open with winrar and copy yourapp which is located in C:/Program Files/Red5/webapps/ into red5.jar. save and close.

4 - restart red5, if you still get net conncetion closed error, reboot your computer :)

How to insert multiple rows into a table in ORACLE

2010-03-17T02:14:00.000-07:00

To insert multiple rows into a table in Oracle, you can use the following syntax:


INSERT ALL
 INTO myTable(no, col1, col2, col3, col4, col5) VALUES (1,2,82,2008,29,9)
 INTO myTable(no, col1, col2, col3, col4, col5) VALUES (2,2,80,2008,34,8)
 INTO myTable(no, col1, col2, col3, col4, col5) VALUES (3,2,82,2008,21,6)
SELECT 1 FROM DUAL;

don't forget
SELECT 1 FROM DUAL;
it's important.

ActionScript3 error: '1119: Access of possibly undefined property through a reference with static type '

2010-02-08T13:17:00.000-08:00

When i implement a simple ActionScript3 MovieClip document class like this:


package {
 
 import flash.display.MovieClip;
 import flash.text.TextField;

 public class Main extends MovieClip {
  
  private var response_text:TextField;

  public function Main() { 
   
   this.respond_text = new TextField();   
   
   addChild(this.respond_text);
  }  
 }
}

I got that strange error.After a little googling i figured out that error(1119) is occured because of casting issues.But solution is simple, replace every occurance of

this.respond_text

with

(this as MovieClip).respond_text

that should solve the problem.

"Function eregi_replace() is deprecated" error in amfphp

2010-02-01T06:08:00.000-08:00

solution:

go to:
/amfphp/core/shared/utils/MethodTable.php

go to line 505:

Replace these lines:

$comment = eregi_replace("\n[ \t]+", "\n", trim($comment));
$comment = str_replace("\n", "\\n", trim($comment));
$comment = eregi_replace("[\t ]+", " ", trim($comment));

By these

$comment = preg_replace("`\n[ \t]+`U", "\n",trim($comment));
$comment = str_replace("\n", "\\n", trim($comment));
$comment = preg_replace("`[\t ]+`U", " ",trim($comment));
