Re: How to share VB code across multiple pages?

Hi, Juan,

Yes, I've set the PATH variable. But I am still getting that error
message.

That said, I have downloaded and installed the ASP.20 Visual Web
Developer kit and issued aspnet_regiis.exe -i.

Now, when I check out my web application, I get this error message:

******************************************
Server Error in '/' Application.
Validation of viewstate MAC failed. If this application is hosted by a
Web Farm or cluster, ensure that <machineKey> configuration specifies
the same validationKey and validation algorithm. AutoGenerate cannot be
used in a cluster.
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: Validation of viewstate

Source Error:

An unhandled exception was generated during the execution of the

the exception can be identified using the exception stack trace below.
