Delete recent file automatically

Recent files Terminator

Windows Recent document is good for us, by this we can open recent document immediately. but in the case of privacy it is not good. because someone can open/see your Important document.
To prevent this you can clear the recent document list. But what will happen when someone immediately came to near you and try to use your system,in this case you have not sufficient time to clear recent document. There are many software are available that clear recent file but they clear the recent file on system start-up or shut down not immediately! The above problem is really interesting.
okay, so I have created this small and powerful utility.
it will remove the recent file immediately and intervals when you open it.
It will help you to protect to see your important document from Other user.

To run this utility you need to install dot net framework 3.5

This is the error which many PHP programmer face in coding.
The most important fixes are listed below:

Image resize without distortion and keeping proportions

Image resize without distortion and keeping proportions.

Image distortion is the normal problem with the image resize in
any programming language. You need to have good knowledge of math to
resizing the image.
I have implemented image resize code without distortion in PHP.
You can easily convert it in the any other programming language
for ex: ASP.Net, JSP etc:

Here is the listed below code:
====================================

img_resize.php

$filename = "https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQOT3CzejzFpMcWAqDQekKgdvDT8f4Ot1gFRIG3UDWN8N8y7kIMAagI85rho803ugEzu5IgQDK9k8FgDxsjKe8xgJ8zpaW8JaejckiKU3tnhYy48q0m2eavUhP9yn9x8cU-t7e4YPepPg/s1600/auto-resume-broken-uploader.jpg";
$nw = 170; // new width
$nh = 128; // new height
header('Content-type: image/jpeg');
list($width, $height) = getimagesize($filename);
if($width<= $nw) {
   $nw=$width;
}
$newHeight = $height*$nw/$width; // calculate new height here
if($newHeight > $nh) {
   $nw = $width*$nh/$height;
   $newHeight=$nh;
}
$image_s = imagecreatetruecolor($nw,$newHeight);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_s, $image, 0, 0, 0, 0, $nw,$newHeight,$width,$height);
imagejpeg($image_p, null, 100);

use it as listed below:
<img src="img_resize.php" />

Note that you can also make the parameter for height and width.
