DB connectivity test and page redirection if connection failed

ASP.Net:

Try
 'Create / Open a connection
 'execute a "Select getdate()" or some other super-light query
Catch ex as Exception
 'Redirect to error page
End Try

Classic ASP:

On error resume next
'create / open a connection
' 'execute a "Select getdate()" or some other super-light query
if err.number <> 0 then
  'Redirect to error page
end if

when test in classic asp i get this error page
Error Type:
Microsoft OLE DB Provider for SQL Server (0x80004005)
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
/WEBDEV/code/devwebscripts/devaccmgr/lwuapcsp.asp, line 15

i tested it with the sql server stopped.

haven't tested it yet in asp.net

Please show the actual classic ASP code you're using that gets this result.

Thanks.

On error resume next
            strQueryCheckDBConnection = "Select getdate()"
            oRsQueryCheckDBConnection = objConn.Execute(strQueryCheckDBConnection)
            if err.number <> 0 then
                  'login with no database connection page
                  Response.Redirect("lwndbcp.asp")
            end if

Which is line 15?  Might line 15 be something before the code you posted?

line 15 is when i try to open a connection:
strDataSourceName is part of an include file.
with the server started i dont get errors, but when not available i get the page error

dim objConn,  strDataSourceName      
Set objConn = Server.CreateObject("ADODB.Connection")

'create a database connection
objConn.connectionstring = strDataSourceName
objConn.Open'=====line 15


=======
objConn.Open
=======

so, i dont have to make check using below query code?

strQueryCheckDBConnection = "Select getdate()"
oRsQueryCheckDBConnection = objConn.Execute(strQueryCheckDBConnection)

Yeah, I guess not.
