Hello

I need to disable the text selection when I open a PDF File with WebBrowser Object.

current code:
Dim fileurl1 As New Uri(filelocation & "#toolbar=0&navpanes=0")
WebBrowser1.Navigate(fileurl1)

Any Ideas would be great
Thanks

It's not the WebBrowser control that would be handling this; it's the Adobe Reader plugin. I don't believe there are any options in the open parameters offered by the Reader plugin (see attached file) that would grant you this functionality.

use javascript
<script language="JavaScript1.2">

function disabletext(e){
return false
}

function reEnable(){
return true
}

//if the browser is IE4+
document.onselectstart=new Function ("return false")

//if the browser is NS6
if (window.sidebar){

document.onclick=reEnable
}

I've tried the first link and right clicking on the WebBrowser1 is now disallowed, but there is still a way to select text and ctrl+C copy it.


I'm not able to figure out how to implement your other 2 links
Could you try to create a small sample Program which is opening an pdf file under c:\
in webbrowser1? that would be great.

Thanks

That's because minhvc's code applies to HTML in the browser. As I said, the browser doesn't control the PDF; it only loads Adobe Reader. Adobe reader controls whether or not you can select text.
