Validation of viewstate MAC failed

S

sck10

Hello,

I have a web project (VS 2008 c#). I have a page that opens, but when I try
to call an assembly (managed c++) on a submit event, I get the following
error on the web server, but not on my development machine. It seems that
this is the only dll in the Bin folder that has this problem. Any help with
this would be appreciated.
Thanks, sck10

This error may be related to submitting a page before it has fully loaded.
If you have a fast connection, it would explain why you can't repro on your
development machine.

The problem is related to information needed as part of the postback was not
loaded, and is therefore not included. So, if that's what you are seeing,
there's not a whole lot you can do about it.
