Using VB 6, sp6,
On sql server 2000 (sp4)

When I try to establish a connection to the database
from a VB 6 program using ADO, I get a similar message
if the UserID does not exist or if the UserID does exist
but does not have the permission to the database.

The NativeError number is different,

NativeError - 18456 The UserID does not exist
NativeError - 4060  The UserID exists, but does not have permission
                    to the database.

Can I hard code the NativeError number in my VB 6
program to determine exactly what happened,
(the UserID did not exist or the UserID does exist but
does not have the proper permission.)

I worry that the code number might change in a future
version of sql server.  

I hate to do this but there is no other way to determine
exactly what happened.

Thanks in Advance,

Laurencel

Since these are SQL Server errors and not ADO error numbers, they will remain the same for backward compatibility, at least in 2000 and 2005 :)

This is the current description in SQL Server 2000:
4060: Cannot open database requested in login '%.*ls'. Login fails.
18456: Login failed for user '%ls'.

And this in SQL Server 2005
4060:  Cannot open database "%.*ls" requested by the login. The login failed.
18456:  Login failed for user '%.*ls'.%.*ls
