Rule number one: When you are writing web based applications, do not use Messagebox.Show
It shows on the server not the client. It seems to work in developement, but fails in a very big way in production, when the message box appears on a server on the other side of the planet where the user can't see it, much to the apoyance of:
1) The user, who doesn't get the message - in fact he gets nothing.
2) The web host administrator, who begins to hate you with a passion...

There are a few options:
1) Create a control on your page, and use that to report problems.
2) Create an error report page, and use that - you may annoy the user though if it causes his data to be lost.
3) Look at the Javascript Alert function - you can cause the client to execute it, displaying a box on the client.
