thread synchronised confused by lock(this)

thread synchronised confused by lock(this)

I hava a class:
public class LockTest
{
public void LockThis()
{
lock (this)
{
Console.WriteLine("lock this test");
System.Threading.Thread.Sleep(5000);
}
}
}
in Main:
static void Main(string[] args)
{
LockTest lockTest = new LockTest();
lock (lockTest)
{
//lockTest.LockThis();
System.Threading.Thread thread = new Thread(lockTest.LockThis);
thread.Start();
}
Console.Read();
}
I thought the invoking lockTest.LockThis() will cause a dead lock but it
didn't. I don't konw why.

Dynamic Div Content with just clicking one link/button

Dynamic Div Content with just clicking one link/button

I need help here please.
I want to show dynamic content to a div. I already have the code below:
<script type="text/javascript"><!--
function ReplaceContentInContainer(id,content) {
var container = document.getElementById(id);
container.innerHTML = content;
}
//--></script>
<div id="example1div" style="padding:10px; text-align:left;">
<p>Content 1</p>
</div>
<p align="center"><a
href="javascript:ReplaceContentInContainer('example1div','<p>Content
2</p>')">View another</a></p>
What it does is, when click the "View another" it replace the 'Content 1'
to 'Content 2' but what I want here is that, when 'Content 2' is already
shown, I want to click the "View another" link again and replace the div
content again with the new content like 'Content 3'.
Anyone please help me solve this.
Thanks in advance :)

Cakephp Upload plugin allows any file extension to be uploaded despite validation rules

Cakephp Upload plugin allows any file extension to be uploaded despite
validation rules

'model' => array(
'rule' => array('isValidExtension', array('xls')),
'message' => 'File does not have a stl extension'
),
Allows absolutely any file to be uploaded. I have this is as my first
validation rule. Other validation rules like notEmpty, and isUnique work
fine on the same form element.
Tried adding stl to the array found in the main behavior: 'extensions' =>
array('xls') - also did not work.
Any idea on what I'm doing wrong here?
Also: This appears to happen regardless of the file extension I pick. No
matter what, it doesn't call the file invalid. The same issue appears to
happen with Mime types as well.
The plugin URL is: https://github.com/josegonzalez/upload

Display Image on Mouseover

Display Image on Mouseover

How do I display an image on mouse over? I also need to underline the text
next to the image on mouse over? On mouseout I have to hide the image and
make the text normal again.
This is my html field
<img src="img.jpg"> Name
Now when I load the page I want not to display the image unless I have the
mouse over the place it should appear.
