Problems writing to database from ASP.NET

I've got a developer who is running into problems getting a web app to write
to a SQL database. I am posting his error message. Any ideas?

There was no way for you to know it (except maybe by browsing through
some of the previous questions before posting yours - always a
recommended practice), but this is a classic asp newsgroup. ASP.Net is
a different technology from classic ASP. While you may be lucky enough
to find a dotnet-savvy person here who can answer your question, you
can eliminate the luck factor by posting your question to a newsgroup
where the dotnet-savvy people hang out. I suggest
microsoft.public.dotnet.framework.aspnet.
There are also forums at www.asp.net where you can find a lot of people
to help you.

Even if we did deal with .Net stuff here, I doubt anyone could help
given the information you've provided. Some code would help, especially
if the code provided contained the line of code that causes the error.
