Some things that do work only when I am on connected to internet

[Eitan M]

Hello,

I have a .NET web application.
I have a *.mdb file,
the connectionString is something like :

conMain.ConnectionString = "provider = microsoft.jet.oledb.4.0; data source
= " _

& Server.MapPath("./db/mydb.mdb")


When I am doing update, or just even simple command :
cmd = new oleDB.oleDBCommand,
system throws me to the unload event,
after that, system run to the next command.

Also when I am doing something like :
retval = cmd.executeNoneQuery(),

system also throws me out.

When I am connected to internet, and run the web application again -
everythings is OK.
It seems that things don't work well to the *.mdb file (maybe some
configurations) when I am not running on the internet.

What may be the reason for the above problem ?

Thanks

Also,
when I running the application on the second time, I got the message :
Error while trying to run project : unable to start debugging on the web
server.
The system cannot find the file specified.

I didn't find out what file ???
