Make a aspx page and write a function which inserts a record in database. on click of button call this event. Once the record gets inserted - Press F5 button from browser and see what happens. You will see same button event gets triggered and inserts one more record.

So lets say now you are submitting a payment transaction to gateway and suddenly net got slow, then you again refreshed the page. This may lead to submission in gateway twice. : - ( bad practice.

This is a very old problem, and most of the users know it. So 99% of the users very carefull to click twice on the same button (if there is no any feedback that something happend).

Also if the users press F5 after a postback most modern browser warn the users that the form already posted back (this true only for regular postbacks)!

Anyway double postback sometime happens, but the solution for this is not disabling the reload button, instead we need some server side logic to prevent this.

Also you dont want user to copy text or images from site - Though possible :- )

Just wondering whether there is any 100% solution for preventing text or image copy from a regular html page?

(Maybe rendering the page's text from thousands of absolutely positioned 1x1 pix divs is a good starting point... [:D])

To be honest i never looked for any solution. What i generally do is redirect user to some other page post completion of event. So new page gets loaded. (if its a payment processing page then always redirect - dont take chance).

But i believe you can acheieve it from firing twice by using following -

1. Captcha - like a box which says to type characters by seeing image. This is generally seen in registration page. This prevents auto form submission.

2. Auto event wireup attribute in aspx page (top line). - You can study more on it.

Hi There,

As far as i know, you cannot disable the refresh button of the web browser.

However, you have optioon to hide the toolbars of the web browser.

Hope it helps!

Just copy paste the below inside html head tag

<script>

document.attachEvent("onkeydown", my_onkeydown_handler); 

function my_onkeydown_handler() 

{ 

switch (event.keyCode) 

{ 

 

case 116 : // 'F5' 

event.returnValue = false; 

event.keyCode = 0; 

window.status = "You can't refresh this page............."; 

break; 

} 

}



</script>

I think if you try to do this your page will be considered harmfull, and most of your first time visitors leave your page forever.

You cannot disable (ever) the refresh button, if you can do this it would be a huge security risk.

But you can use for example the window.onunload event do something, this event will be triggered whenever the user try to leave the current page (by navaigating away, by refreshing, by closing it etc.)

Disabling right click with JavaScript

<html>
<head>
<script language ="javascript">
function Disable() {
if (event.button == 2) 
{
alert("This action is not possible")
}
}
document.onmousedown=Disable;
</script>
</head>
<body>
</body>
</html>

Disabling right click with JavaScript <script language=javascript> function Disable() { if (event.button == 2) { alert("This action is not possible") } } document.onmousedown=Disable; </script>

Disabling right click with JavaScript

What is the point? The user just need to disable javascript for the page and get the right click, F5, etc. back [;)]

Good question try this

So lets say now you are submitting a payment transaction to gateway and suddenly net got slow, then you again refreshed the page. This may lead to submission in gateway twice. : - ( bad practice.

Also you dont want user to copy text or images from site - Though possible :- )

Dont forget to mark the answer - if its helpful and also let others know the correct one : -)

Just tested some commercial html text encryptor solution (just choose what get the most hit by google), using firefox + web developer + firebug.

It looks promising to the regular user at first (no right click, no text selection, select all and copy to notepad from the edit menu show encrypted text, saved page useless etc.)

But disabling all javascript by web developer turn off all protection, using firebug very easy to see and save the whole page as original. [666]

So trying to "encrypt"/"protect" the text is pointless (just wondering who pay for this?)

Also pointless "protecting" images.

Maybe obfuscating javascript files worth the effort (I don't know how effective against code stealing this technique.)

Hi WorldClassCoders,

Hey, I tried this what is the reason behind this.

Why the button call twice time events. Is it possible to avoid twice time calling event, if yes how?

thanks & regards

Priya.

Hey, I tried this what is the reason behind this.

Google for [postdata resend], to understand what is this.

Is it possible to avoid twice time calling event, if yes how?

This is not possible. But it is possible to add some logic in the event:

- detect that the record is already in the database?

- save a flag in the viewstate which set for only the first save and subsequent save can be discarded?, etc.

Unfortunately the ajax stuff multiply the problem because the refresh, back and forward buttons simply broken down with ajax. This is a big problem (ajax caching problem).

What do you want to do with this attribute (how it prevents double post)? Thanks.
