Microsoft Sidewinder 2 Precision joystick driver

Been trying out the X-Plane simulator and I must say it's much better then MS Flight Simulator X

I am using a 13 year old Microsoft Sidewinder 2 Precision joystick and realized it's so hard to find the windows driver for this thing. Microsoft even does not have it on their support pages which frankly does not surprise me.

Lucky I found mine in the shoe box covered in dust!

So for anyone that still has one of these gems, here is the driver in ISO format ready to burn to CD

Increase Username field for Silent Registration in Virtuemart. Allows for long email addresses to be used as a username

FOR Joomla 1.0.x & Virtuemart 1.10.x only

use phpMyAdmin to modify jos_users

Change Type/Length of username field from 25 to 255

Edit File:

administrator\components\com_virtuemart\classes\ps_shopper.php

Line: 174

Change Code:

$silent_username = substr( str_replace( '-', '_', $d['email'] ), 0, 25 );

To:

$silent_username = substr( str_replace( '-', '_', $d['email'] ), 0, 255 );

Editincludes/joomla.php file

find the lines

// check that username is not greater than 25 characters

$username = $this->username;

if ( strlen($username) > 25 ) {

$this->username = substr( $username, 0, 25 );

To:

$username = $this->username;

if ( strlen($username) > 25 ) {

$this->username = substr( $username, 0, 25 );

To Increase in com_registration

Lightbox Modal Effect

-in your scripts.js goes:

SqueezeBox.initialize({});

$$('a.lightbox').each(function(el) {

el.addEvent('click', function(e) {

new Event(e).stop();

SqueezeBox.fromElement(el);

});

});

OR if no domready

window.addEvent('domready', function() {

SqueezeBox.initialize({});

$$('a.lightbox').each(function(el) {

el.addEvent('click', function(e) {

new Event(e).stop();

SqueezeBox.fromElement(el);

});

});

});

-in template your index.php, to call Joomla's Mootool engine...before html goes:

JHTML::_('behavior.modal');

-In article ADD class="lightbox" example:

NOTE Replace [ ] with <>

[a class="lightbox" href="images/stories/image.jpg"][img class="noborder" src="images/stories/small_image.jpg" border="0" alt="Image" /][/a]

How to add and validate extra field in contact form (com_contact)

- component/com_contact/views/contact/tmpl/default_form.php

- component/com_contact/views/contact/controller.php

TO MAKE A FIELD VALIDATE ADD class="inputbox required" to input field thats reads as:

Repalce [] with <> below

[input type="text" name="name" id="contact_name" class="inputbox required" value=""]

===============================================

Example: to catch Form post PHONE FIELD

add

$phone = JRequest::getVar( 'phone', '', 'post' );

to line 116 in controller.php

add

.$phone.

to line 178 which reads

$body = $prefix."\n"."Name: ".$name."\n"."Phone: ".$phone.' <'.$email.'>'."\r\n\r\n".stripslashes($body);

To ADD into the default_form.php ADD (remember to replace [] with <> tags below)

[label for="contact_phone"] [?php echo JText::_( 'Phone' );?]:[/label]

[input type="text" name="phone" id="contact_phone" size="30" class="inputbox" value="" /]

Auto Expand Sections/Categories in Extended Menu Module for Joomla 1.5

The solution for this is altering some files from the module:

modules/mod_exmenu-j15/exmenu/loader/autoexpandedmenu.menuloader.class.php

Change lines 177 to 192 from:

Code:

switch($menuNode->type) {
case 'content_category':
case 'content_blog_category':
case 'content_archive_category':
if ($contentItemVisible) {
$this->categoryMenuNodeList[] =& $menuNode;
}
break;
case 'content_section':
case 'content_blog_section':
case 'content_archive_section':
if (($categoryVisible) || ($contentItemVisible)) {
$this->sectionMenuNodeList[] =& $menuNode;
}
break;
}

to:

Code:

$tipoMenu = $this->getRawUrlParameter($menuNode->link, 'view');
switch($tipoMenu) {
case 'category':
if ($contentItemVisible) {
$this->categoryMenuNodeList[] =& $menuNode;
}
break;
case 'section':
if (($categoryVisible) || ($contentItemVisible)) {
$this->sectionMenuNodeList[] =& $menuNode;
}
break;
}

This will do the work to generate the links, but Extended Menu won't give then the proper classes when they are active, so it's needed to change one more file:

modules/mod_exmenu-j15/exmenu/loader/menuloader.class.php

Change lines 297 to 303 from:

Code:

switch($task) {
case 'view':
case 'edit':
case 'cancel':
$result = $id;
break;
}

to:

Code:

$result = $id;
