Hey,
You can add error handling at the application level, to trap unhandled errors, and show a more informative error. However, the best approach would be to figure out what the actual problem is. I am on my phone just now, but i will take a proper look at your code later.

well gep it is basically exception that should throw when i uplaod my applciation on server
but it gives me generalized kind of error
Server Error in '/' Application.

The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /ErrorPage.aspx
It looks to me that you are getting an unhandled error on the page and in your web.config you have set "/ErrorPage.aspx" as the default or other page to go to in this event. The problem is /ErrorPage.aspx does not exist... and so you are getting a second error (404 not found).
Check your web.config and that errorPage.aspx exists where you specify.
i have config like this
Code:<customErrors defaultRedirect="ErrorPage.aspx" mode="RemoteOnly">
<error statusCode="404" redirect="filenotfound.aspx" />
</customErrors>
Ok, so that is the first part of what brin was asking. Does that file exist on the server?
