Web Browser Disable Right Click

Hi All,

I'm sure this must have been asked a million times due to it's usefulness,
but are there any sensible solutions for disabling right click (and other
services such as Ctrl+P, Browser hotkeys etc) on a Web-Browser control in
VB.NET?

Despite Googling for ideas on and off for a week now, I only found one
solution and this was to implement IMessageFilter on the form and then trap
all the incoming messages. Unfortunately, this also prevents the user from
being able to move my application (something to do with trapping right
clicks), along with other useful things like being able to use the backspace
key!

Is there any other way of doing this? Or is there some way I can trap
messages that go into the Web-browser control BEFORE it processes them and
AFTER my Form has? Surely somebody must have come up with an efficient way
of hosting a customized browser in a .NET WinForm!

TIA

Don't know if this would be of any help, but in the VB world, the
WbCustomizer control that Microsoft made available could be used to
suppress any the context menu and/or speed keys (all or individual). The
WbCustomizer was provided with soource code (it was a c++ project). Given
that it came with source, perhaps that could be modified to work under the
DotNet environment.

one easy way to block the right click is to put this code into the html page

<body oncontextmenu=" Return false;">

there are more complicated ways of doing it from .NET, but this hasa always
worked fine for me.

well, this helps part of it...

make that R lowercase:

"return false;"

You can use this to block other events too, but only in the HTML.

Hi Alex

The interface you need to implement is IDocHostUIHandl er. It has a method
ShowContextMenu . If you return an HRESULT of S_OK in your implementation of
this method this will cancel the context menu on right-click. It also allows
you to implement your own context menu.

In your form that host the WebBrowser control, implement IDocHostUIHandl er.
Then, in the DocumentComplet e event, get the ICustomDoc interface from the
document object, and call SetUIHandler(Me ). Finally, wait for the readystate
to go to complete.

You could have a look at this complete thread:

What's the point of disabling the rightmousebutto n. I hate websites that
do that since I navigate by using the rightmousebutto n (rightclick and
choose back in mozilla). What is it that you want to prevent? Sourcecode
stealing? Image stealing? If so, just disabling the rightmousebutto n
isn't the way to go since that is just a wax nose. The user can still do
all those things from the menu (i.e. save page to disk).
