Hi,
I ahve a windown application which uses webbrowser control for displaying video coming from a CGI interface. It uses a activex component to display the video stream. This works fine in XP. but when I try to run this on 64 bit window I got error
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt. ". Though on some 64 bit system it works fine .

How to resolv this issue?

Here is my stack trace

System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

The ActiveX component is crashing. Contact the vendor of this control for support.

Hi nobugz,
Many thanks for your response.

Initially I also guessed so, but if I refer the same URL through IE it works fine....Only when I refer it by webbrowser control in my windows application it crashes.

On a 32 bit system also I am getting same error as I tested it on win 2008 32 bit.
